When Audi introduced its all-new A3 generation in the U.S. in 2014, only the sedan was offered with the promise that the popular Sportback version would be coming. That follow-up is the A3 e-tron, the exclusive A3 Sportback choice here in the 2016 model year. This exclusivity makes this $37,900 A3 e-tron all the more special.

The A3 e-tron plug-in hybrid makes use of the same 150-horsepower, 1.4 liter TFSI gasoline engine and six-speed S tronic transmission as conventional Sportbacks available in offshore markets. The e-tron adds a liquid-cooled, 102 horsepower electric motor to deliver a satisfying 7.6 second 0 to 60 mph launch and the kind of spirited driving experience expected of an Audi.

The car’s lithium-ion battery pack is located beneath the rear bench seat, allowing fold-flat seats and the hatchback utility of a Sportback since there’s no battery intrusion in the cargo area. This battery allows up to 17 miles of all-electric driving to handle typical around-town driving chores.

Driving on battery and hybrid power delivers an overall driving range of just under 400 miles. Fuel economy is an EPA estimated combined 89 MPGe when running on battery power and 35 mpg in hybrid mode.

Audi likens its A3 Sportback as kind of a Swiss Army Knife of hybrids because of its four selectable driving modes. EV mode provides pure electric driving, the default mode at every start. Hybrid mode chooses the most efficient power and is ideal for long distances. Hold Battery mode preserves charge and saves EV power for later use. Charge Battery mode charges the battery during highway driving to ensure plenty of electric range when returning to an urban area.

With the A3 Sportback e-tron, Audi set out to prove that efficiency and performance can co-exist in a premium vehicle, without sacrifice. By all measures it has accomplished this goal.

Toyota’s all-new 2016 Prius promises to deliver the very attributes beloved by its legions of fans over the years with significant technology updates. Its recent reveal in Las Vegas and subsequent release of additional information shows that it clearly is an all-new generation, but one that doesn’t stray too far afield from the familiar design that’s recognizable at a glance. That’s probably a good thing for Toyota since over 3.5 million Prius models have been sold globally, with 1.8 million in the U.S. alone. So…why rock the boat?

Highlights to the 2016 Prius include a more refined exterior design, new double wishbone suspension attached to an all new vehicle platform for enhanced driving dynamics, and an expected 10 percent improvement in mpg. Conceivably, that could move the non-plug-in Prius close to the 60 mpg mark. The new design stretches the Prius 2.4 inches longer than the previous model with slight width and height expansions, all in the name of greater passenger comfort and cargo area.

The 2016 Prius is based on Toyota’s New Global Architecture, which allows models to share components and platforms for manufacturing efficiencies and cost savings. This new architecture brings tangible benefits like a lower center of gravity, increased body rigidity, and a more responsive suspension package to improve overall handling and safety.

CLOSER LOOK AT NEW PRIUS TECH

The new Prius retains its 1.8-liter engine but it’s been completely re-engineered for improved performance, better fuel economy, size and weight reductions, and a maximum thermal efficiency of 40 percent. Improvement comes partly through a large-volume exhaust gas recirculation (EGR) system and advancements in combustion efficiency.  A redesigned air intake port improves airflow inside the combustion chamber. Coolant passages have been redesigned to optimize internal engine temperature. Low-viscosity oil reduces friction between sliding engine components and friction created by the piston skirts, rotating parts and oil pump has been reduced.

Fuel efficiency gains also come from improvements to heating performance. An active grille shutter opens and closes the grille as necessary in response to outside temperatures. The exhaust heat recirculation system has also been improved and made more compact. In yet another nod to efficiency, this recycles exhaust heat from the engine to the coolant to be reused in heaters and warm the engine.

The transaxle and motor have been redesigned to reduce weight. The motor is considerably more compact with a better power-to-weight ratio and offers a 20 percent reduction in mechanical losses through friction.  The new-generation Prius will be available with either new lithium-ion or nickel-metal hydride battery packs with increased energy density. This allows the battery to be relocated beneath the rear seat, increasing cargo space.

There is also a new color head-up display that projects essential vehicle data and alerts on the lower section of the windscreen. A Smart-flow (S-FLOW) air conditioning system improves efficiency by detecting whether the front and rear passenger seats are occupied, adjusting ventilation and heating performance accordingly by minimizing air flow around empty seats.

An optional Toyota Safety Sense package, previously reserved for upscale Lexus products, is available in 2016 and may become standard equipment in 2017. The TSS package includes a Pre-Collision System with Pedestrian Detection that alerts a driver if a collision is imminent. It also brings the car to a halt if a pedestrian is detected ahead of the car while driving under 18 mph.  Full-speed Dynamic Radar Cruise Control will slow or stop the vehicle to avoid collisions as well. A Lane Departure Alert with Steering Assist signals a driver if it senses the car drifting from the lane and also assists with steering input when needed. Automatic High Beam control turns the high beams on and off depending on traffic to enhance nighttime driving.

Toyota’s all-new 2016 Prius is sleeker and more efficient than the current model despite the fact that a first glance delivers that familiar Prius look. For the market the Prius successfully brings into the fold, this is likely a good thing. It is clear that the new Prius, nine years in the making, will continue to be a highly recognizable signpost on the green car highway.

 

The Acura NSX supercar is taking a long time to reach the reality of showrooms, years after the automaker’s late-2011 announcement that it would be offering a successor to the original NSX. It’s now expected to begin manufacturing in Marysville, Ohio in spring 2016. When it goes on sale in a time frame that sees competitors introducing early 2017 models, NSX fans will have been waiting over four years to witness the model’s rebirth. By all indicators it will be worth the wait.

Acura has taken a rather innovative approach in creating the NSX successor that replaces the previous generation last seen in 2005. The new NSX is an all-wheel-drive hybrid with power supplied by a 3.5-liter, mid-ship V-6 and three permanent-magnet synchronous AC electric motors. It will produce an expected 500-plus horsepower.

The V-6 is all-new and shares nothing with other Honda/Acura engines. Its 75-degree 3.5-liter DOHC V-6 features dry sump lubrication, twin turbochargers, and intercooling. The engine is mated to a new, nine-speed dual-clutch transmission integrated with the rear electric motor. This motor, mounted at the front of the transaxle, can power the NSX up to 50 mph for only a few miles since the car’s lithium-ion battery is limited in capacity. The rear motor's primary purpose is to add torque when needed for maximum performance.

Up front there’s a Twin Motor Unit consisting of two smaller electric motors, each powering a front wheel via a planetary gearset. When used with the rear brakes, this provide a torque-vectoring capability. The driver can select between quiet, sport, sport-plus, and track modes to tailor the driving experience.

Much has been done to keep weight down and the center of gravity low. For starters, there is a carbon-fiber floor panel and part of the rear subframe uses proprietary aluminum-casting technology for stiffness and low weight. The aluminum-intensive space-frame structure is joined together by self-piercing rivets, flow-drill screws, welding, and much adhesive. High-strength steel is used in the super-thin A-pillars. The hood and doors are aluminum while the fenders are SMC, a common form of fiberglass. An aluminum or carbon-fiber roof can be ordered.

Performance is expected to include a 0–60 mph time of 2.7 seconds, 0–100 mph in 6.4 seconds, and a 190 mph top speed. Plus, as if that kind of performance excitement isn’t enough, an even hotter version is planned. For those who can afford the price of entry, the coming Acura NSX will mean that gasoline-electric hybrid power has never looked so good.

 

Long-term tests provide a great way to learn what it's like to live with a vehicle on a daily basis. Our time with a fully-loaded,  2014 Accord Hybrid Touring proved enlightening over more than a year's worth of commuting, running errands, and road trips. This 50 mpg sedan, a high-profile offering within Honda’s Accord lineup that won Green Car Journal’s 2014 Green Car of the Year® award, is sleek, stylish, and sophisticated in an unassuming way. It’s also packed with desired technology. While we won't see a plug-in hybrid back in the Honda Accord line until the 2017 model year, here are our thoughts on its predecessor. No doubt, the new generation Accord plug-in will be even better.

Unique design features distinguish this Accord Hybrid from the already-pleasingly aggressive style of the standard Accord, which was introduced as an all-new model in 2014. These include LED daytime running lights and blue-accents on front light lenses, grille, and rear LED tail lamps, plus a decklid spoiler and unique wheels. Our tester is further distinguished with a dealer-installed Honda aero package with front, rear, and aide underbody spoilers. We were amused when we first drove our stealthy-black Accord Hybrid test car to a local restaurant and drew appreciative gazes from patrons, with one asking, ‘Is that a new Mercedes?” Nope, a Honda…a really, really cool one.

Power is supplied by Honda’s Two-Motor Hybrid Intelligent Multi-Mode Drive (i-MMD) system, a mouthful-of-a-name that earns its ‘intelligent’ designation. The 196 horsepower hybrid system achieves optimum efficiency through intelligent and seamless transitions between all-electric drive, internal combustion drive, and hybrid drive depending on driving circumstances.

We’ve found the hybrid sedan to be responsive and confident on the road during our drives through the twisty canyons along California’s Central Coast. There’s always ample power at the ready, delivered through a capable electric continuously variable transmission (E-CVT). Eco mode can be selected to tone down performance a bit to enhance fuel efficiency. The Accord Hybrid’s regenerative braking system feeds electricity back to the car’s lithium-ion batteries immediately upon lifting off the accelerator, rather than starting when braking is applied.

All this brings a very impressive 50 mpg city fuel economy rating and 45 mpg on the highway. With the Accord’s 12.2 gallon fuel tank, filling up always shows a whopping miles-to-empty read of well over 600 miles. This considerable driving range has come in handy many times during extended road trips, including a trek from our offices on the Central Coast to San Diego and back on a single tank.

These drives are often made with the Accord’s adaptive cruise control engaged, a feature that automatically keeps a safe driving distance from the car ahead. It works seamlessly in adapting to traffic speed and flow and is actually quite amazing. Drives are smooth and comfortable both on the open road and in traffic.

Time spent in the Accord Hybrid Touring’s accommodating cabin comes with an immersion of advanced electronics complemented by an 8-inch multi-information display and an audio touch screen compatible with smart phone features. Its electronics user interface is easy to use and driver assistive technologies invaluable, including Forward Collision Warning, Lane Departure Warning, and rear view camera with LaneWatch blind spot display.

So here’s the bottom line after 15,000 miles behind the wheel of the Accord Hybrid: Great styling, a bevy of advanced electronics, a quiet and accommodating cabin, and impressive efficiency – all wrapped in an aggressively handsome package – have made the award-winning Accord Hybrid a joy to drive and one of our favorites for quick jaunts and road trips alike.

Five exceptional ‘green’ cars have just been identified by Green Car Journal as its finalists for the coveted 2016 Green Car of the Year® award. These 2016 models include the Audi A3 e-tron, Chevrolet Volt, Honda Civic, Hyundai Sonata, and Toyota Prius.

GREEN CAR AWARD PROGRAM

Since 1992, Green Car Journal has been recognized as the leading authority on the intersection of automobiles, energy, and environment. The GCOY award is an important part of Green Car Journal’s mission to showcase environmental progress in the automotive field.

The auto industry’s expanding efforts in offering new vehicles with higher efficiency and improved environmental impact mean there is an increasing number of vehicle models to be considered for the Green Car of the Year® program. This is a significant departure from when just a limited number of new car models were considered for the inaugural Green Car of the Year® program, which Green Car Journal first presented at the LA Auto Show in 2005.

During the award’s vetting process, Green Car Journal editors consider all vehicles, fuels, and technologies as an expansive field of potential candidates is narrowed down to a final five. Finalists are selected for their achievements in raising the bar in environmental performance. Many factors are considered including efficiency, EPA and CARB emissions certification, performance characteristics, ‘newness,’ and affordability. Availability to the mass market is important to ensure honored models have the potential to make a real difference in environmental impact.

The Green Car of the Year® is selected through a majority vote by a jury that includes leaders of noted environmental and efficiency organizations including Jean-Michel Cousteau, president of Ocean Futures Society; Matt Petersen, board member of Global Green USA; Dr. Alan Lloyd, President Emeritus of the International Council on Clean Transportation; Mindy Lubber, President of CERES; and Kateri Callahan, President of the Alliance to Save Energy. Green Car Journal editors and celebrity auto enthusiast Jay Leno round out the award jury.

Green Car Journal will announced the winner of the 2016 Green Car of the Year award during press days at the L.A. Auto Show on November 19.

 

There are many outspoken and polarizing proponents of the various fuels and technologies at play today. This has been the case for several decades now and isn’t likely to disappear anytime soon. Many electric car enthusiasts do not see a future for internal combustion or even hydrogen fuel cell vehicles. Hydrogen proponents point out that fuel cell vehicles make more sense than battery electrics since hydrogen generally offers greater driving range and fuel cell vehicles can be refueled in under five minutes, while battery electrics cannot. Biodiesel enthusiasts point out the obvious benefits of this biofuel and even as this fuel gains momentum, wonder why support isn’t stronger. Natural gas advocates see huge and stable supplies of this clean-burning fuel now and in our future, without the truly significant commitment to natural gas vehicles this should bring. And those behind internal combustion vehicles achieving ever-higher efficiency simply wonder what the fuss is all about when conventional answers are here today.

So in the midst of all this, where are we headed? Simple. In the right direction, of course.

As I was writing about these very fuels and technologies some 25 years ago, it wasn’t lost on me that the competition for dominance in the ‘green’ automotive world of the future would be hard-fought and long, with many twists and turns. As our decades-long focus on the ‘green car’ field has shown us, the state-of-the-art of advanced vehicles in any time frame is ever-changing, which simply means that what may seem to make the most sense now is likely to shift, and at times, shift suddenly. This is a field in flux today, as it was back then.

When Nissan powered its Altra EV back in 1998 as an answer to California’s Zero Emission Vehicle mandate, it turned heads with the first use of a lithium-ion battery in a limited production vehicle, rather than the advanced lead-acid and nickel-metal-hydride batteries used by others. Lithium-ion is now the battery of choice, but will it remain so as breakthrough battery technologies and chemistries are being explored?

Gasoline-electric hybrids currently sell in ever-greater numbers, with plug-in hybrids increasingly joining their ranks. Conventionally-powered vehicles are also evolving with new technologies and strategies eking levels of fuel efficiency that were only thought possible with hybrid powerplants just a few years ago.

What drives efficiency – and by extension determines our future path to the high efficiency, low emission, and more sustainable vehicles desired by consumers and government alike – is textbook evolution. Cars are adapting to meet the changing needs of future mobility and the imperative of improved environmental performance. Some of these evolutionary changes are predictable like lightweighting, improved aerodynamics, friction reduction, and enhanced powertrain efficiencies. Other answers, including the fuels that will ultimately power a new generation of vehicles, will be revealed over time.

So here’s to the cheerleaders who tell us quite vocally that their fuel, technology, or strategy is the answer to our driving future. One of them may be right. But the fact is, the evolutionary winner has yet to be determined.

Chevrolet introduced the Cruze Turbo Diesel in 2014, the first diesel sedan from an American nameplate since the less-than-stellar diesel cars Detroit offered in the late 1970s and early 1980s. It’s a world of difference. Actually, GM brought the European Cruze 2.0-liter turbodiesel to the Cruze powertrain lineup here, a well-proved engine that accounts for about 40 percent of all Cruze models sold in Europe. The Chevrolet Cruze Diesel returns for 2015 with only minor cosmetic changes.

The 2015 model we test drove is easily recognized from the 2014 version by its revised grille and front fascia, influences that came from the Chevy Impala and Malibu. Inside, minor changes include revised cup holders, relocating the trunk-release button to the center console, and door lock buttons now on the door. Features include everything offered on Cruze LS and 1LT models, plus a sport-tuned suspension, 17 inch alloy wheels, four-wheel disc brakes, leather-appointed seats, heated front seats, 6-way power-adjustable driver seat, remote vehicle starter system, and LED running lights.

Likewise, there is no change to the 2.0-liter ECOTEC turbodiesel four-cylinder from last year, an engine that produces 151 horsepower and 264 pound-feet of torque with at least 250 pound-feet of torque between a low 1,750 and 3,000 rpm. The dual overhead camshaft (DOHC), 16-valve engine has an overboost capability that increases torque to an estimated 280 pound-feet during short bursts of stronger acceleration for about 10 seconds. The Cruze Diesel can accelerate from 0-60 mph in about 8.6 seconds and you can feel this diesel’s expected low-end torque coming on strong within a few seconds of hard acceleration from a stop.  An Aisin AF-40 six-speed automatic transmission handles the car’s higher torque.

As expected, fuel economy is the Cruze Diesel's strong suit.  With an EPA-estimated 46 highway mpg, this means the thrifty Cruze can travel 717 miles on its 15.6 gallon fuel tank. City efficiency is an EPA estimated 27 mpg and 33 mpg combined. An aero performance package that integrates a lower front grille air shutter, mid-body aero panels, and front air dam help achieve its higher fuel efficiency.

The version sold here in the States was adapted to meet more stringent Tier 2 Bin 5 emission standards as well as a wider range of driving conditions, including higher altitudes and colder weather. For example, ceramic glow plugs are used rather than conventional metal glow plugs to provide better cold starts. An engine oil heater is optional for cold climates.

Importantly, this diesel engine emits at least 90 percent less nitrogen oxide (NOx) and particulate emissions compared to previous-generation diesels. A diesel particulate filter (DPF) and urea injection are used.  The exhaust after-treatment system uses technology similar to that found in GM's Duramax diesel engines for heavy-duty trucks and vans. Those seeking an additional level of environmental performance will appreciate that the engine is B20 biodiesel compatible.

Connectivity is enhanced with features like text message alerts for smartphone users with incoming texts through the car’s speakers, plus Siri Eyes Free for iPhone iOS 6 and iOS 7. Voice -controlled connectivity aims to mitigate distracted driving by helping keep phones in pockets and hands on the wheel. Popular available options include a seven-inch color touch screen and navigation. Expanding MyLink capability is OnStar with 4G LTE and a standard Wi-Fi hotspot to provide a mobile hub for staying connected. A three-month/three gigabyte data trial is provided.

The 2015 Cruze received a 5-star Overall Vehicle Score for Safety from the National Highway Transportation Administration. Standard safety features include 10 standard airbags. A rear vision camera, Rear Cross Traffic Alert, and Side Blind Zone Alert are available. Chevy’s best-selling model worldwide with more than three million sold since its 2010 launch, the Cruze is offered in LS, LT, RS, LTZ, and Eco models. Its base MSRP starts at $16,995 with the diesel model available at $26,485.

Chevy’s 2015 Trax subcompact SUV offers a new choice for those who want the functionality of an urban-friendly crossover with higher fuel efficiency. With an overall length of 168.4 inches and a smaller physical footprint than many crossovers, it also features a tight 36.7-foot turning diameter that makes for great maneuverability in city traffic

The Trax is based on the subcompact Chevrolet Sonic hatchback but is actually quite a bit larger, allowing it to carry 48.4 cubic feet of cargo and up to five people. It’s built in Korea like the Sonic, and while new to the U.S. market the Trax is already available in over 60 global markets. Along with the Sonic, its platform, mechanics, and cabin layout are shared with the Buick Encore.

Power comes from a 1.4-liter, turbocharged four-cylinder Ecotec engine featuring dual overhead cams and variable valve timing. The engine, also made in Korea, produces 138 horsepower at 4900 rpm and 148 pound-feet of torque at 1850 rpm. Around-town driving is spirited with good acceleration and snappy shifts courtesy of a Hydra-Matic 6T40 six speed automatic transmission and front-wheel drive. All-wheel drive is a $1500 option.

Like many downsized crossover SUVs in recent years, the Trax aims at highway fuel efficiency in the 30-plus mpg range, a goal met with its EPA-estimated 34 mpg highway fuel economy and 26 mpg in the city.  The AWD version is rated at 31 highway and 24 city mpg. The fuel tank holds 14 gallons.

Though on the smallish side, the Trax offers an interior that’s quite versatile. The 60/40 folding rear seats and a fold-flat front passenger seat allow carrying items up to 8 foot long as needed. The Trax is quite narrow so accommodating three in the rear is a bit tight, although we found rear seat headroom and legroom to be just fine.

The Trax comes with full power equipment including electric power steering, air-conditioning, and a rearview camera. Front wheel drive variants get front disc and rear drum brakes with the AWD featuring four wheel discs. An LT Plus package adds a six-way power driver’s seat, leather-wrap steering wheel, and rear parking sensors. The uplevel LTZ comes with leather upholstery, 18 inch wheels, heated front seats, an auto-dimming mirror, and a Bose sound system. Other versions use cloth seat materials and 16 inch wheels.

Safety is a notable feature of the Trax, which received five stars from the National Highway Transportation Safety Administration for overall, frontal, and side crash protection and a Top Safety Pick award from the Insurance Institute for Highway Safety. There are 10 airbags including front and rear side airbags, full-length side curtains, and front knee airbags.

Buyers will appreciate this crossover’s approachable $20,995 base price and two year/24,000 miles of free scheduled maintenance. Also appealing is the model’s high level of electronics technology that comes as standard or optional equipment. This includes a 7-inch MyLink touchscreen, On-Star 4G LTE with built-in WiFi hotspot, Siri Eyes Free for iPhone, a USB port, an iPod interface, OnStar emergency telematics, and a BringGo navigation app.

 

For a decade, Green Car Journal has been recognizing vehicles that significantly raise the bar in environmental performance. With automakers stepping up to offer ever-more efficient and ‘greener’ vehicles in all classes, the magazine’s awards program has naturally expanded to include a greater number of awards for recognizing deserving vehicles.

This prompted the recent suite of Green Car Awards presented during Policy Day at the Washington Auto Show in the nation’s capital – the 2015 Green SUV of the Year™, 2015 Green Car Technology Award™, and 2015 Luxury Green Car of the Year™.

BMW’s gull-wing i8 earned the distinction as the 2015 Luxury Green Car of the Year, outshining competitors Audi A8 L TDI, Cadillac ELR, Porsche Panamera S E-Hybrid, and Tesla Model S. Aimed at aspirational buyers who value superb styling and exceptional performance combined with the efficiency of plug-in hybrid drive, the i8 is unique among its peers with an advanced carbon fiber passenger body shell. It also features a lightweight aluminum drive module with a gasoline engine, lithium-ion batteries, and electric motor. The i8 can drive on battery power for 22 miles and up to 310 miles on hybrid power.

The Jeep Grand Cherokee EcoDiesel rose to the top as the magazine’s 2015 Green SUV of the Year, besting finalists Honda CR-V, Hyundai Tucson Fuel Cell, Lexus NX 300h, and Mazda CX-5. Offering excellent fuel efficiency for an SUV of its size, the Grand Cherokee EcoDiesel’s 3.0-liter EcoDiesel V-6 offers up to 30 highway mpg and is approved for B20 biodiesel use. An Eco Mode optimizes the 8-speed transmission’s shift schedule, cuts fuel feed while coasting, and directs the air suspension system to lower the vehicle at speed for aerodynamic efficiency.

The Ford F-150 was honored with the 2015 Green Car Technology Award for its milestone use of an all-aluminum body. Competing for the award were advanced powertrains in the BMW i3, BMW i8, Chevrolet Impala Bi-Fuel, Ford F-150, Honda Fit, Kia Soul EV, Tesla Model S, VW e-Golf, and Volvo Drive-E models. The F-150’s aluminum body enables the all-new 2015 pickup model to shed up to 700 pounds for greater efficiency and performance.

While the Green Car Technology Award has a history at the Washington Auto Show, the first-time Green SUV of the Year and Luxury Green Car of the Year awards could not have existed just a short time ago. Simply, SUVs and luxury vehicles were seldom considered ‘green,’ and for good reason. An SUV/crossover’s mission was to provide family transport and recreational capabilities, while aspirational/luxury vehicles were expected to deliver the finest driving experience combined with high-end appointments and exceptional design. Both categories held few environmental champions and ‘green’ was hardly an afterthought.

The evolving nature of ‘green’ cars has brought about a fundamental shift in which environmental performance is now important in SUVs and luxury vehicles. Even so, not all models in these classes are created equal. The challenge has been finding the right balance – the ‘sweet spot’ – that finds SUVs and luxury vehicles delivering the efficiency and environmental qualities desired without sacrificing the conventional touchstones – quality, safety, luxury, value, performance and functionality – that consumers demand. This year’s winners of the 2015 Green Car Awards clearly achieve this balance.

Presenting these important awards at the Washington Auto Show is compelling considering its reputation as the ‘Policy Show,’ a result of the show’s proximity to Capitol Hill and the influence that Washington DC has in driving a more efficient generation of vehicles to market. The 2015 Washington Auto Show has also expanded in recent years, receiving accreditation from the Organisation Internationale des Constructeurs d'Automobiles (OICA) as one of the five top tier auto shows in America. This year’s Washington Auto Show featured more than 700 vehicles from over 42 domestic and import auto manufacturers, plus a Green Car Awards exhibit showcasing 15 finalist vehicles within the show’s Advanced Technology Superhighway exhibit area.

Jeep's impressive Grand Cherokee EcoDiesel, the model that just drove away with Green Car Journal's 2015 Green SUV of the Year award at the 2015 Washington Auto Show, is one SUV that's sure easy to like. At least that's what we kept thinking during a recent 500 mile trip in a Grand Cherokee Limited test vehicle.

While not a small vehicle by any means, the Grand Cherokee is easy to maneuver and, for a 4x4, offers a surprisingly accommodating ride. Plus, the EcoDiesel variant is very efficient as far as full-size SUVs go, delivering fuel economy that tracked well with its 22 mpg city/30 mpg highway EPA ratings. Long-time SUV drivers will surely share that this is amazingly efficient for a full-size, full capability Sport Utility Vehicle.

Those considering a Jeep Grand Cherokee have a mind-boggling number of choices in models, powertrains, and option packages, with the base model starting at $30,000 and uplevel trim packages ranging up to $64,500. Our Grand Cherokee EcoDiesel test vehicle offered a base price of $36,395 but landed closer to $50,000 with the added Luxury Group, Adventure Group, and Unconnect packages, the latter offering desired electronics like premium navigation, HD radio, and SiriusXM Traffic.

On-board electronics is a big deal in most models these days and the Grand Cherokee is no exception. Electronics is well-looked-after with standard fare like remote start, 7-inch multi-view display, rear back-up camera and back-up assist, ready alert braking, tire pressure monitoring, and integrated voice command with Bluetooth.

The Luxury Group package in our test vehicle upgrades the display to an 8.4-inch touch screen and also adds features like self-leveling Bi-Xenon HID headlamps and automatic high-beam headlight control, rain-sensitive windshield wipers, and Napa leather ventilated seats.

While buyers have other V-6 and V-8 gasoline engine choices, those wanting the best fuel economy combined with maximum towing capacity will naturally opt for the 3.0-liter EcoDiesel V-6. Rated at 240 horsepower and 420 lb-ft torque, this powerhouse-of-an-engine is sufficient to tow 7,400 pounds and delivers welcome performance.

In addition to the Grand Cherokee Limited we drove, the 50-state diesel is also available in Overland and Summit versions. With full-time four-wheel-drive like our test vehicle, the model’s EPA numbers are 22 mpg city/30 mpg highway/25 mpg combined fuel economy – high numbers for a large vehicle with this level of functionality. Another positive is the EcoDiesel’s range of up to 730 miles between fill-ups. We completed our considerable road trip without fueling up, a welcome experience.

The Jeep Grand Cherokee’s diesel engine is supplied by Italy's VM Motori and was developed in collaboration with Fiat Powertrain Technologies. While VM Motori has had many owners – Detroit Diesel, DaimlerChrysler, Penske, etc. – it is now a 50-50 joint venture between GM and Fiat. Over the years, virtually every auto manufacturer has used VM Motori diesel engines at one time or another.

Fiat's MultiJet II common-rail injection, water-cooled exhaust-gas recirculation Selective Catalyst Reduction (SCR), and 16.5:1 compression ratio enable the 24-valve, dual-overhead-cam engine to meet stringent Tier II, Bin 5 and ULEV II emissions rules. It is designed to use Ultra Low Sulfur Diesel (ULSD) and is approved for B20 (20 percent biodiesel/80 percent petrodiesel). Other features include a water-cooled, variable-geometry turbocharger, 60-degree cylinder banks, chain-driven camshafts, and low-voltage ceramic glow plugs for quicker cold-weather starts.

There is an Eco Mode to maximize economy by controlling items like transmission shift schedule, idle speed, and interactive deceleration fuel shut off, the latter cutting fuel feed when coasting. Eco Mode is automatically engaged at startup. A button on the center stack can be used to disengage Eco Model when more sporty performance is desired. While engaged, Eco Mode directs the Jeep’s Quadra-Lift air suspension system to lower the vehicle at speeds above 55 mph, providing for better aerodynamic efficiency. On 4WD models in 4H, Eco Mode also alters the front-to-rear torque split to increase fuel economy.

The model’s Selec-SpeedControl feature, which includes both Hill Ascent Control and Hill Descent Control, assists when ascending steep grades. Hill Descent Control helps monitor throttle, speed, and braking when traveling down a hill, while Hill Start Assist keeps brakes applied after removing your foot from the brake, allowing time to accelerate without rollback.

The 4x4 version gets Quadra-Trac II that offers all-speed traction control. An electronic limited-slip differential transfers up to 100 percent torque to the wheels when needed to lend year-round traction on wet or dry surfaces. As is the case with 4WD vehicles, shifting into low-range provides rock-crawling prowess.

We returned from our journey impressed not only with this vehicle’s functionality in carrying people and cargo, but its ability to do so in comfort and style. Plus, of course, there’s the Grand Cherokee’s all-important efficiency and impressively long driving range between fill-ups.

Those who need a full-size SUV that can handle any mission with complete confidence, while doing so in ways that require far less fuel than one would reasonably expect, should consider placing the Grand Cherokee EcoDiesel on their short list. Its efficiency, capabilities, and general do-everything attitude earned it Green Car Journal's 2015 Green SUV of the Year for these, and many other, very good reasons.

Well, this should be no surprise. Reuters reports what we’ve suspected all along because there’s a long history of this happening: Low gasoline prices are negatively impacting the sale of alternative fuel vehicles including those running on natural gas and electricity.

Not surprisingly, with lower gasoline prices comes a decided uptick in purchases of larger and lower efficiency vehicles, especially SUVs. Beyond personal transportation, the commercial sector is also being hit hard because the cost differential involved in buying large natural gas trucks presently fails to pencil out well compared to conventionally powered models.

Is this a trend? Only short term, really. Green Car Journal editors have noted such occurrences over the past two decades and the trend has always ebbed and flowed with varying fuel prices, incentives, and other factors. While the long-term prospects for battery electric vehicles hinge on lower cost batteries in the future, hybrids and high efficiency conventional vehicles are here to stay.

The Consumer Electronics Show is a big deal in the consumer electronics industry. With the expanding integration of advanced electronics into cars it has become a high-profile venue for auto manufacturers as well, with automaker CEOs giving keynote addresses and auto press conferences growing in volume. Most of these involve connectivity, autonomous driving, and other advanced on-board systems. But the scope is expanding significantly as CES is growing ever-brighter on the automakers’ radar.

A case in point is Chevy’s move to provide a sneak peek of its all-new 2016 Chevy Volt extended range electric car at 2015 CES. This preempts the official debut of the new Volt at the coming North American International Auto Show (NAIAS) in Detroit, one of the auto industry’s premier events.

The ‘peek’ was just that – a teaser showing the new Volt’s front end and a bit of the driver’s side, with the rest blocked with purposeful positioning and a strategically placed speaker tower. Still the front end view showed a handsome evolutionary design with the partial profile that could be seen indicating a somewhat smaller model with a redefined roofline and window design. It has been previously disclosed that the 2016 Volt will use a new 1.5-liter engine-generator, a bigger battery pack, and offer additional range.

Chevrolet’s all-new 2015 Colorado midsize pickup seeks to fill a potentially hot market replete with buyers interested in the functionality of a truck but requiring a bit smaller package for better maneuverability in urban areas. Starting at an MSRP of $20,120, the Colorado is available in four-door extended cab or crew cab models to fit varying needs, offering a standard six-foot pickup bed with a short five-foot bed also available on a short bed crew cab versions. Rear seat room is very tight in the extended cab and reasonably comfortable in the crew cab.

Power choices include two fuel efficient engines, a 2.5 liter four-cylinder and a 3.6 liter V-6.  The four-cylinder is rated at 200 horsepower and 191 lb-ft of torque, with approximately 90 percent of the peak torque available from 2,000 rpm to 6,200 rpm. The V-6 engine is rated at 305 horsepower and 269 lb-ft of torque. Fuel economy is estimated at 18 city/26 highway mpg with the V-6 and bumps up to 20 city/27 highway mpg with the four-cylinder. A new clean diesel option is coming with the 2016 Colorado, which will be offering a new 2.8-liter Duramax engine featuring an expected 181 horsepower and a sizeable 369 lb-ft of torque coming on at a low 2,000 rpm. Fuel efficiency promises to be outstanding for a pickup.

Aluminum blocks and forged-steel crankshafts, along with dual-overhead camshafts with variable valve timing, direct injection, and jet-spray piston cooling are shared by both of the current gasoline engines. The Colorado's trailering rating is up to 7,000 pounds with the V-6 engine and heavy-duty towing package. All models come with a standard six-speed automatic transmission with auto grade braking and a tow/haul mode. Extended cab 2WD WT models equipped with the 2.5-liter engine are available with a six-speed manual transmission.

The Colorado features triple-sealed doors inlaid in the body sides for improved aerodynamic performance and a quieter interior. To help keep overall mass down, lightweight materials such as an aluminum hood are used. It also has active aero grille shutters, designed to enhance aerodynamics when closed. Electric power steering improves efficiency by eliminating the energy used by an engine-driven hydraulic pump.

With nearly the capacity and features of the full-size Chevrolet Silverado pickup, this mid-sized pickup offers not only better fuel economy, but enhanced maneuverability including  a short turning radius of 41.3 feet, great on city streets or backing a trailer into a camping spot.

The Colorado may be a pickup, but it offers the advanced electronics so desired by consumers today. Safety is also top-of-mind with forward collision alert and lane departure warning plus a standard rear-vision camera.

The road to higher efficiency is an appealing one these days and driving a small car is one way to get there. While it’s true that not everyone is in the market for a small car, the appeal grows if small means efficient and highly functional but not constrained or boring.

This is the theme with Honda’s third-generation 2015 Honda Fit, which offers a more aerodynamic look and additional interior space while retaining the previous version's overall physical footprint. Honda designers have clearly gone the extra mile in not only offering a thoroughly modern small car, but innovating ways to bring greater interior functionality than should be expected in this size package.

Helping achieve this is the Fit's ‘Magic Seat’ rear seat setup that offers four modes for carrying passengers, cargo, or both. In the Utility Mode, it can carry 52 cubic feet of cargo. Fold down the right sides of the rear and front passenger seat in the Long Mode and you can carry items up to 7 feet, 9 inches in length. In the Tall Mode there’s nearly 4 feet of room available top to bottom. Remove the front head restraints, fold back the front seats, and you can relax, or even sleep, in the Refresh Mode.

Beyond this refreshing small car functionality, perhaps the Fit’s most important change is a new and more fuel-efficient powertrain. Its new direct-injected, 1.5-liter, four-cylinder Earth Dreams engine produces 130 horsepower, 13 more than the engine it replaces.

A six-speed manual transmission is standard, but most will be fitted with a continuously-variable transmission (CVT) that has shift paddles and a Sport mode that provides seven selectable ‘gears’ to increase the fun factor. This CVT comes with Eco Assist and an ECON button for more fuel efficient operation. All models also feature Honda's Eco Coaching function that prompts drivers to achieve maximum fuel economy.

With the 6-speed, the Fit achieves EPA estimated numbers of up to 33 mpg in the city and an impressive 41 mpg on the highway, achieving desirable efficiency with a gasoline engine that only comes with a hybrid in some other models. Not only do drivers save on gas, but also on purchase price since the 2015 Fit offers a base MSRP of just $15,525 that makes this model approachable for most new car buyers.

I was changed by the 1990 introduction of the GM Impact electric car prototype at the Los Angeles Auto Show, then again by the amazing array of electric, hydrogen, and ‘green’ vehicles I witnessed at the 1991 Tokyo Motor Show. I knew that 'green' cars would be important. So, for 25 years now, this has been my focus at Green Car Journal and also at GreenCarJournal.com, plus an additional six years while feature editor at Motor Trend.

Covering this field for 25 years lends an invaluable perspective that’s important to understanding not only where we’ve been, but where we’re headed. There’s plenty of ‘green’ car news to share these days so it’s important to place it in context…and yes, that comes again with perspective and having been there while this all unfolded.

It has been enlightening to document the early research and development of the vehicles we take for granted today. While there is no crystal ball for predicting the automobile’s future, I’ve long been fascinated by researching patents for advanced and alternative fuel vehicle technologies because this does reveal what automakers and their technology suppliers have in mind for the years ahead.

Several decades ago, many of these vehicles and technologies were but ideas to potentially pursue, the subject of technology deep dives I attended, or opportunities that allowed driving advanced technology test mules on the track at automakers’ proving grounds.

Two of these experiences in the 1990s come readily to mind – driving a Japanese-market Toyota Crown sedan outfitted with an early gasoline-electric hybrid drive and a Geo Storm equipped with a prototype battery electric powertrain. These powerplants evolved to become the Hybrid Synergy Drive powering Toyota’s Prius and the electric drivetrain powering the GM EV1. The production versions were worlds better than the early prototype powertrains, lending the perspective to see just how far the technology had come.

Early developmental electric drive vehicles were often quirky and unexpectedly noisy in myriad ways, with high-pitched motor controller frequency noise and gear whine very apparent against a near-silent background devoid of internal combustion. The first natural gas vehicle prototypes often suffered from an annoying high-volume gaseous fuel injector clatter. Developmental hydrogen fuel cell vehicles sacrificed loads of space for large and cumbersome fuel cells and hydrogen storage. High efficiency diesel vehicles of decades past were unacceptably loud and emitted soot. Gasoline cars with high fuel economy were small, often lacking the creature comforts consumers expect and an illustration that sacrifice was required to achieve efficiency. Accomplishing extremely low tailpipe emissions often came at the expense of performance.

Drive an electric, natural gas, hydrogen fuel cell, high mpg gasoline, or high efficiency diesel personal-use vehicle today and they are quiet, usually quick, and ‘normal’ in all respects. A great many conventional internal combustion vehicles are now near-zero emission…not that you’d know it because they achieve this so seamlessly. We have great ‘green’ vehicles today because a lot has transpired over the past 25 years. Perspective.

I am confident that all of these vehicles, technologies, and fuels will play an important part in our motoring future. If the past 25 years are any indication, the vehicles we’ll be driving in the years ahead will be just amazing.

Over the 10 year history of Green Car Journal’s Green Car of the Year award program, there has never been a battery electric car that has been compelling enough to be recognized as the best-of-the-best in an ever-expanding field of ‘green’ cars. That has changed with the groundbreaking BMW i3, Green Car Journal’s 2015 Green Car of the Year^®.

The BMW i3 came out on top of a field of finalists that included the Audi A3 TDI, Chevrolet Impala Bi-Fuel, Honda Fit, and VW Golf. The array of technologies and fuels represented included high efficiency gasoline, electric drive, clean diesel, and natural gas.

BMW’s i3 stands out as one of the most innovative vehicles ever to be introduced by any major automaker. It breaks the mold – literally – with a strong and lightweight body using materials and technology at home on the race track, and now used for the first time to construct a mainstream production car. It is a milestone, forward-thinking approach.

Meeting both near-term and far-reaching goals is no easy thing. The challenge is to design and build cars that offer meaningful environmental achievement while delivering the traditional touchstones desired by new car buyers, among them comfort, safety, convenience, connectivity, performance, and value. Also important in the world of advanced vehicles like battery electric cars is a significant commitment to the manufacturing and sale of these vehicles that goes beyond a few thousand units sold in select geographical areas. BMW’s commitment with the i3 is focused not only nationally in the U.S., but globally as well.

Offering a lightweight carbon fiber reinforced plastic (CFRP) body on an aluminum space frame, BMW’s innovative i3 brings environment-conscious drivers all-electric drive with an optional internal combustion range extender. The most unique aspect of the i3 is the car’s body structure, which incorporates the first-ever use of carbon fiber reinforced plastic (CFRP) to form the body and passenger cabin of a mass-production vehicle. CFRP is as strong as steel and 50 percent lighter. It is also 30 percent lighter than aluminum.

This BMW’s drive module includes an electric drivetrain, 5-link rear suspension, and an aluminum structure. Its lithium-ion battery pack is mounted mid-ship beneath the floor. Strategic placement of the 450 pound battery pack and drive components provides a very balanced 50-50 weight distribution to enhance handling and performance.

Acceleration is crisp, with a 0-60 elapsed time of 7.2 seconds provided by an electric motor producing 170 horsepower and 184 lb-ft torque. With a curb weight of just 2,700 pounds, the i3 has is sprightly even at highway speeds. Strong regenerative braking characteristics often allow the i3 to be driven with just the accelerator pedal in city driving. When a driver lets off the accelerator, regen slows the car quickly and allows it to come to a complete stop without touching the brake pedal.

Charging at home with an available 220 volt charger delivers a full charge in about three hours. Where available, public DC fast charging can bring an i3 to 80 percent state-of-charge in 20 minutes and a full charge in 30 minutes. The i3 BEV features an 81 mile EPA estimated range on batteries. The i3 REx, equipped with an internal combustion range extender that creates on-board electricity as needed to help keep batteries charged, features a 72 mile battery driving range and 150 miles total with the range extender.

Efficiency is a given. EPA rates the i3’s city fuel economy at 137 MPGe (miles per gallon equivalent) and 111 MPGe on the highway, with a combined 124 MPGe. For the REx-equipped model, EPA rates mileage at 117 MPGe combined.

The 2015 Green Car of the Year^® is selected by a majority vote of an award jury comprised of Green Car Journal staff and invited jurors, including TV personality and car aficionado Jay Leno plus leaders of the nation’s most high-profile environmental and efficiency organizations. These jurors include Jean-Michel Cousteau, president of Ocean Futures Society; Matt Petersen, board member of Global Green USA; Mindy Lubber, President of CERES; Kateri Callahan, President of the Alliance to Save Energy; and Dr. Alan Lloyd, President emeritus of the International Council on Clean Transportation.

The diversity of new car models at showrooms today reflects an evolving and sophisticated market in which a growing number of new car buyers have decided that environmental performance must meet their needs and expectations, on their terms. As it happens, 2015 Green Car of the Year jurors have clearly decided that this year, the electric BMW i3 does it best.

 

It is an exciting time to be involved with the auto industry, or to be in the market for a new car. The auto industry has responded splendidly to the challenge of new emission, fuel economy, and safety standards. The public is offered a greater than ever selection of vehicles with different powertrains, lightweight materials, hybrids, and electric drive vehicles across many platforms. We see increasing numbers of clean diesel vehicles and natural gas is making a resurgence, especially in the heavy-duty sector.

The positive response by the auto industry to the ever-tightening pollutant emission and fuel economy standards includes tactics such as the use of aluminum in the Ford F-150 and the increased use of carbon fiber by BMW, among many innovations introduced across many models and drivetrains. These evolutionary changes are a major tribute to the automobile engineers who are wringing out the most they can in efficiency and reduced emissions from gasoline and diesel engines. I view this evolutionary change as necessary, but not sufficient to meet our greenhouse gas goals by 2050.

New car ownership is currently down in Europe and is leveling off in the U.S. For global automotive manufacturers, however, this trend is offset by the dramatic growth in places like China and India. The potential for dramatic growth in the developing world is clearly evident: In the U.S., there are about 500 cars per thousand people, compared to about 60 and 20 in China and India, respectively.

How can these trends be reconciled with the environmental and health concerns due to climate change and adverse air quality in the developing world? The evidence for climate change accumulates by the day. Hazardous air quality in many major cities in China has drawn global attention, providing a visual reminder of how far the developed world has come and how much environmental protection needs to be accelerated in the developing world. Damaging air pollution is increasingly seen as a regional and even worldwide challenge. Dramatic economic growth in many developing countries is generating pollution that knows no boundaries. Air pollution from China, for example, fumigates Korea and Japan and is even transported across the Pacific to impact air quality in California and other Western states.

It will take a revolutionary change to provide personal mobility without unacceptable energy and environmental consequences. As a recent National Academy of Sciences (NAS) document states, it is likely that a major shift to electric drive vehicles would be required in the next 20 to 30 years. Electric drive vehicles, coupled with renewable energy, can achieve essentially zero carbon and conventional pollutant emissions. The NAS report also predicted that the costs of both battery and fuel-cell electric vehicles would be less than advanced conventional vehicles in the 2035-2040 timeframe.

This transition will not occur overnight and we will be driving advanced conventional vehicles for many years to come. In a study for the International Council on Clean Transportation, Dr. David Greene calculated that the transition could take 10 to 15 years, requiring sustained investment in infrastructure and incentives in order to achieve sustained penetration. While this investment is not inexpensive, it is projected that the benefits of this investment will be 10 times greater than the costs.

So where do we stand today on electric vehicles? We are seeing an unprecedented number of hybrid, plug-in hybrid, and battery electric vehicles across many drivetrains and models. There were about 96,000 plug-in electric vehicles sold or leased in the U.S. last year and more than 10 new PEV models are expected this year. While the sales fall short of some optimistic projections, it is an encouraging start after many years of more hope than delivery. The FC EV is expected to see significant growth after the initial limited introduction of fuel cells in the 2015-2017 timeframe by five major automobile companies.

It will take many years of sustained increasing penetration into new car sales to make this revolution a success. It is indeed a marathon and not a sprint. The challenge is how to ensure sustained sales of electric drive vehicles in the face of the many attributes of advanced technology conventional vehicles.  Electric drive vehicle drivetrains have an affinity with the increasing amount of electronics on board the vehicle, which might ultimately yield very interesting, capable, and competitive vehicles.

I have little doubt that if we are serious about our energy, environmental, and greenhouse gas goals the revolution in technology will occur. All the major automobile companies seem to recognize this in their technology roadmap, which includes advanced conventional vehicles, plug-in hybrid vehicles, battery and fuel cell electric vehicles.

In conclusion, the next 20 years promise to be equally as challenging and exciting as the last 20 years. I have little doubt that the automobile engineers are up to the task ahead, but whether we have the political fortitude to stay the course to achieve the necessary air pollution and GHG reductions is far less certain.

The Ram 1500 EcoDiesel, a powerhouse pickup that offers the only advanced, fuel-efficient diesel engine in the light-duty truck segment, has earned the distinction as Green Car Journal’s 2015 Green Truck of the Year™.  The award was presented at the San Antonio Auto & Truck Show in San Antonio, Texas, in the state that justifiably lays claim to being ‘truck country.’

Green Truck of the Year™ honors a truck that best exemplifies what can be achieved when environmental performance is viewed as important as traditional core values like functionality, payload, towing capability, and versatility. Blending environmental achievement with these traditional characteristics is not easy, and in many cases it’s also not cheap. But it is needed. Auto manufacturers are now placing significant new emphasis on trucks that achieve improved fuel efficiency, feature better overall environmental performance, and in some cases run on alternative fuels.

In addition to the Ram 1500 EcoDiesel, this year’s award finalists included the all-new Ford F-150, Chevrolet Colorado, and GMC Canyon pickups, plus the efficient gasoline Ram 1500 HFE. Each of these pickups brings its own brand of efficiency and improved environmental performance to bear in the truck market.

The Ram 1500 EcoDiesel distinguishes itself with a powerful and highly efficient powerplant that breaks new ground in the light-truck segment, accomplishing its mission of improved environmental performance without sacrificing the core values important to truck buyers. The engine produces 240 horsepower and a substantial 420 pound-feet of torque while offering rather impressive fuel economy, at least by pickup truck standards, with official EPA estimates of 20 mpg in the city and 28 mpg on the highway. This exceptional fuel efficiency provides a driving range of over 700 miles between fill-ups. The pickup is available in Regular Cab, Quad Cab, and Crew Cab versions with either two- or four-wheel drive.

Some of the key features of the 60-degree V-6 EcoDiesel engine include a dual overhead camshaft with 24 valves, cast iron block with aluminum heads, and a 15.5:1 compression ratio. A 29,000 psi common rail fuel injection system with solenoid injectors is used. The engine is equipped with a diesel oxidation catalyst, diesel particulate filter, and selective catalyst reduction to make it emissions-compliant in all 50 states. It can also use B20 biodiesel fuel.

Along with its considerable towing, hauling, and people-handling capabilities, the Ram 1500 EcoDiesel intelligently focuses on efficiencies with active aerodynamics including grill shutters that close for less drag at highway speeds. Other efficiency measures like an eight-speed automatic transmission and an air suspension system that lowers the truck at higher speeds are used to optimize fuel economy and achieve lower greenhouse gas emissions.

When Chrysler introduced the first clean diesel engine in the light-duty pickup segment, there was no way to know just how many pickup buyers would be won over and drive one away from the showroom. Today, production of this truck model has doubled beyond expectations and continues to gain momentum. It was clearly a breakthrough move for the Ram brand and a deserving winner of the 2015 Green Truck of the Year™ award.
