Some cars leave an impression that lasts a lifetime. The Ford Mustang is one of those cars for me. As a kid, I was blessed with a dad who always had something unique in the driveway, from a Morris Minor to a Triumph Herald. None were exotic or expensive, but they were fun and more than a little quirky.

So, when the first generation Mustang came out, Dad had to have one and in the summer of 1964 there was a 1964 1/2 Mustang convertible in our driveway. It was copper with a white interior and white top. Powered by a 289 V-8 and a ‘three-at-the-knee shifted manual transmission. Detroit was producing big iron at the time and this car seemed lean, efficient, and mean. Many happy hours were enjoyed in that first generation Mustang.

When Ford offered to let me drive a 2015 Mustang not long ago, I was understandably thrilled. Then I read the specs. The car would be a four-cylinder with an automatic transmission. No, really?

If you want to know how far the automotive industry has advanced in the last 50 years, go drive the new 2.3-liter EcoBoost four-cylinder Mustang. For those of us of a certain vintage let me clarify, this is not a Pinto engine. This 2.3 is a beast. The first time I pushed the start button, the raspy growl made it clear that the EcoBoost means business. This engine, produces 310 horsepower and 320 lb-ft torque. At just 137.5 cubic inches it’s less than half the displacement of Dad’s 289 V-8.

For perspective, consider that this new four-cylinder also makes more horsepower than the 2005 Mustang GT 4.6-liter V-8 of just 10 years ago. EcoBoost uses smaller, more efficient engine designs aided by turbocharging to do more with less. It’s not a new idea, but Ford has been refining it for years with impressive results. The 2.3 Mustang engine uses a twin-scroll turbo with split exhaust runners to feed immediate boost. It produces low-end power more like a V-6 or V-8 than a four, delivering a very satisfying driving experience.

I’ve always preferred manual transmissions, but the six-speed auto in the Mustang was quite nice. It can be manually shifted with paddle controls on the steering wheel for more control and fun.

The best part about this whole equation is that the EcoBoost engine is lighter than V-6 and V-8 counterparts. That makes all vehicle dynamics simply work better. Everything from acceleration to handling and braking are improved. The car literally feels lighter and is more nimble, which makes it a joy to drive.

Now for the ‘green’ part. The EcoBoost Mustang has an EPA highway fuel economy rating of 32 mpg. This car is quick and will spring from 0-60 mph is 5.6 seconds. But we also decided to push it in the other direction and see how it would do in economy cruise mode. At legal speeds, mid-to upper 30 mpg averages are easily obtainable. You can use this car as a daily commuter and not break the bank.

It’s an interesting and compelling contrast to look back 50 years to the first Mustang, and even 10 years to the last generation Mustang. But what I love most is that this iconic car still has swagger and will stir emotions. I’ll take that over an automotive appliance any day.

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.

 

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.

The Ram ProMaster City, a new model on U.S. highways made possible by the international depth of Fiat-Chrysler Automobiles, is distinguished in many ways. This was underscored at the 2015 San Antonio Auto Show with its win of Green Car Journal’s 2016 Commercial Green Car of the Year™ award. The model bested finalists that included the Chevrolet City Express, Ford Transit Connect, Mercedes-Benz Metris, and Nissan NV200.

Based on the successful and long-running Fiat Doblò model in Europe, the ProMaster City compact van is essentially the same vehicle but tailored for the American market with updates like a slightly higher ride height and heavier-duty suspension. It is available as a Tradesman Cargo Van or five-passenger Wagon to fit diverse needs, at starting MSRPs of $23,445 and $24,445, respectively.

 

Functionality and efficiency are what this vehicle is all about. Interior space is quite generous considering its compact exterior dimensions that aim at ease of operation in urban traffic. In fact, the ProMaster City features best-in-class payload and cargo capacity, allowing drivers to carry up to 1,883 pounds or 31 cubic feet of cargo.

Its floor area between the rear wheel wells is 48.4 inches wide. Driver convenience is enhanced with an available Uconnect 5.0 audio and multimedia system featuring a five-inch touchscreen, integrated voice command with Bluetooth, and steering wheel audio controls.

The ProMaster City’s class-exclusive front-wheel drive system utilizes a 2.4-liter Tigershark four-cylinder engine, an efficient Fiat-developed powerplant widely used in Chrysler models ranging from the Chrysler 200 and Dodge Dart to the Jeep Cherokee and Renegade. This rather sophisticated SOHC engine – at least by work truck standards – features variable valve timing, variable valve lift technology, and a 10.0:1 compression ratio, plus of course Fiat's efficiency-enhancing Multiair technology. The 178 horsepower engine is mated to a standard nine-speed automatic transmission.

This combination moves the ProMaster City from 0-30 mpg in about 3.7 seconds, more than adequate performance in city environs. The ProMaster City offers EPA estimated fuel economy of 21 mpg in the city and 29 mpg on the highway, very good numbers for a van of any kind.

 

 

Even the best fuel saving technology can be negated by poor driving habits. Thus, many of the latest vehicles come with features that help you drive ‘smarter’ to save fuel. The simplest provide feedback through computer displays showing instantaneous and average mpg, range to empty, and more. More sophisticated displays may also graphically indicate efficient driving, like leafs turning greener.

Some vehicles have more active features that coach drivers so they can drive more efficiently. By staying in the green within the blue and green ‘coaching bars’ in Honda's Eco Assist display, drivers can see in real-time how they can achieve higher mpg. Pressing the system’s green ECON button also causes the engine and other energy-consuming systems to automatically operate more efficiently.

Similarly, BMW Driving Dynamics Control allows choosing between Eco Pro, Comfort, Sport, and Sport+ driving modes. Along with shutting down unnecessary systems that consume power, Eco Pro includes a coasting function that decouples the engine from the drivetrain when the accelerator is released between 30 and 100 mph.

Fiat's eco:Drive provides efficiency feedback after a trip, not during it. While driving, eco:Drive records data that can be transferred to a memory stick plugged into its USB port. This data can then be accessed on a PC or laptop to enable a driver to review how well they did. An ecoIndex scores driving skills on a 100 point scale. Tutorials provide tips on how to score better and scores can be compared to tell if driving skills are improving.

With Nissan's Eco Pedal, the accelerator pedal pushes back against a driver’s foot to encourage accelerating in a fuel-efficient manner. More aggressive acceleration is available if the driver pushes harder. Additionally, an instrument panel provides four levels of indication depending on acceleration – no light when the vehicle is stopped, green with appropriate pedal pressure, flashing green with almost-unfavorable pressure, and amber for unfavorable pressure.

 

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.

The BMW i8, the second milestone model to emerge as part of BMW’s innovative ‘i’ sub-brand, earned the distinction as Green Car Journal’s 2015 Luxury Green Car of the Year™ at the recent Washington Auto Show in the nation’s capital. There are compelling reasons for this.

BMW’s flagship i8 not only breaks new ground in defining how a high performance vehicle can achieve environmental goals, but it does so in ways that do not impose limitations on the driving experience. Importantly, this car fits BMW's ‘Ultimate Driving Machine’ image while providing levels of environmental performance increasingly appealing to those buying aspirational vehicles.

BMW i8 LIFEDRIVE ARCHITECTURE

Beneath its stunning, gull-winged body is BMW’s innovative LifeDrive modular architecture. The Life module is essentially the i8's 2+2 passenger compartment constructed primarily of strong and lightweight carbon fiber-reinforced plastic (CFRP), created with carbon fiber manufactured at a dedicated SGL Automotive Carbon Fibers LLC facility in the State of Washington. The result of a joint venture between SGL Group and BMW Group, this manufacturing plant strengthens the i8’s environmental credentials further by producing carbon fiber using renewable hydroelectric energy.

The i8’s aluminum Drive module contains the gasoline engine, lithium-ion battery pack, electric motor, and associated electronic components. It uses a 228 horsepower, 1.5-liter turbocharged three-cylinder engine to power the rear wheels through a six-speed direct shift transmission. Front wheels are driven by a 129 horsepower electric motor and two-stage automatic gearbox. Energy is supplied by a 7.1-kilowatt-hour lithium-ion battery pack located within a tunnel between the two front seats. It can be fully charged in just an hour and a half.

Power can be provided solely by the electric motor for about 22 miles of zero-emission driving at speeds up to 75 mph. Together, the rear-mounted engine and front electric motor deliver all-wheel drive performance with a combined maximum power of 357 horsepower and 420 lb-ft of torque. Drivers are afforded the latest in advanced on-board electronics and safety systems expected in this class of vehicle.

Driving the i8 at speed provides a clear understanding of just what BMW has accomplished with its lightweight, high-tech luxury sports coupe. Green Car Journal editors found the i8’s handling superb and performance exhilarating. BMW’s Driving Dynamics Control allows choices of eDRIVE, ECO PRO, SPORT, and COMFORT drive settings. In Sport mode, the i8 can accelerate from zero to 60 mph in 4.4 seconds and deliver a top speed of 155 mph. Driving range is 310 miles under normal driving conditions. Engine overrun and regenerative braking are used to charge the battery pack and a start-stop feature helps conserve energy.

The BMW i8 blends thrilling performance, innovative design, and environmental achievement in an exceptional luxury sports coupe, while offering a combined EPA city/highway battery electric efficiency rating of 76 MPGe (miles-per-gallon equivalent). Its DNA is 'green' by nature and design, making it a natural selection for 2015 Luxury Green Car of the Year™.

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.

 

It’s well understood that Ford’s EcoBoost engines combine direct injection, variable valve timing, and turbocharging to achieve impressive power and high efficiency. While these advanced engines deliver the acceleration and high fuel economy desired in mainstream models, EcoBoost engines also power the automaker’s performance-oriented models like the Mustang and Fiesta ST. As die-hard enthusiasts always wonder…is there a way to eke even more performance from my car?

And the answer is ‘yes,’ with new hand-held programmers from Ford that adjust a multitude of engine parameters. Tuners often go the traditional route of replacing original equipment with aftermarket parts like performance camshafts, exhaust and intake manifolds, high-flow fueling systems, and even superchargers, sometimes with unwanted trade-offs in efficiency, durability, or comfort.

Ford points out that in an age of computer-controlled engines, a better answer is performance mods using Ford Racing’s programming handset. The $595 ProCal programmer for the Focus ST 2.0-liter EcoBoost engine and Fiesta ST 1.6-liter EcoBoost plugs into the car’s diagnostic link connector port, enabling performance tweaks to everything from throttle response characteristics and idle speed to turbo wastegate control, fuel curves, and spark timing.

In the hands of engine tuning experts, tweaking with the ProCal can bring impressive gains in horsepower and torque output. The Focus ST can gain up to a 90 lb-ft torque increase while maintaining the Ford-backed limited warranty. Custom engine calibrations for the all-new Mustang 2.3-liter EcoBoost are being developed by Ford Racing with a product expected by the end of 2015.

 

 

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.

A steady stream of advanced powertrains, new fuel-efficient systems like stop/start, and more alternative fuels have helped raise fuel economy to new heights in recent years, but the latest breakthrough in energy-efficient cars may surprise you: safety technology. 

You got it. Safety equals green. New safety systems are fuel economy game-changers, because fewer crashes mean less congestion, less fuel use, and fewer carbon emissions.

Recently in a white paper on autonomous vehicles, the National Highway Traffic Safety Administration (NHTSA) noted that “Vehicle control systems that automatically accelerate and brake with the flow of traffic can conserve fuel more efficiently than the average driver. By eliminating a large number of vehicle crashes, highly effective crash avoidance technologies can reduce fuel consumption by also eliminating the traffic congestion that crashes cause every day on our roads.”

NHTSA is referring to a new generation of energy-saving, life-saving technologies on our roads – and often these systems are money-saving and time-saving, too.

Real-time navigation in cars helps drivers keep their eyes on the road while diverting them around traffic. The Texas Transportation Institute estimates that, in 2011, congestion in 498 metropolitan areas caused Americans to travel 5.5 billion hours more and buy an extra 2.9 billion gallons of fuel, for a congestion cost of $121 billion.

Adaptive cruise control is a new driver assist that automatically keeps a safe distance from the car ahead, keeping traffic running smoothly. A report by MIT estimates that a 20 percent reduction in accelerations and decelerations should lead to a 5 percent reduction in fuel consumption and carbon emissions.

The Federal Highway Administration estimates that 25 percent of congestion is attributable to traffic incidents, around half of which are crashes. Sophisticated automatic braking technology helps drivers avoid crashes, and fewer fender benders improve fuel economy since drivers spend less time idling in traffic.

In the future, autonomous cars may enhance road safety while giving us a leg up on fuel efficiency. After analyzing government data, Morgan Stanley observed, “To be conservative, we assume an autonomous car can be 30 percent more efficient than an equivalent non-autonomous car. Empirical tests have demonstrated that level of fuel savings from cruise control use/smooth driving styles alone. If we were to reduce the nation’s $535 billion gasoline bill by 30 percent that would save us $158 billion.”

With all these benefits, clearly the traditional definition of ‘fuel economy’ is restrictive and counter-productive. We can achieve much more with a broader view. Here’s how.

The federal government established a national fuel economy/greenhouse gas program with the ambitious goal to nearly double fuel economy by 2025. Our compliance is based on the fuel efficiency of what we sell, not what we offer for sale. While consumers have more choices than ever in energy-efficient automobiles, if they don’t buy them in large volumes, we fall short. So we will need every technology available to make this steep climb.

We can still squeeze more fuel savings from safety and congestion-mitigation technologies, but these systems reduce fuel use in ways not apparent in government mileage tests so the government doesn’t consider them towards meeting federal standards.

The federal government should recognize the real-world fuel economy improvements from these safety technologies. In fact, the government can encourage their deployment by allowing automakers to count the demonstrated fuel economy benefits of these safety technologies towards meeting their compliance with the federal fuel economy program.

While automakers don’t advocate speeding, we are urging regulators to put the pedal to the metal on this priority. More rapid adoption of these new technologies will help keep drivers safer, avoid traffic congestion, save time, save money, and reduce fuel use.

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.

The Ram 1500 EcoDiesel, a model already leading the pickup pack in fuel efficiency, just keeps getting better. The pickup’s new HFE (High Fuel Efficiency) version now bumps up the clean diesel model’s highway fuel economy by another mile per gallon, delivering the highest fuel economy of all current full-size pickups.

Like the standard EcoDiesel model, the HFE’s efficiency is achieved in part by an eight-speed automatic transmission, stop-start system, thermal management system, pulse-width modulation, and active aerodynamics that includes grille shutters and air suspension that lowers the truck at speed for better aerodynamics. The new HFE variant gets a unique trim package and is available with a body-colored fascia adopted from the Ram Express model for a sporty appearance, plus distinguishing HFE badging, of course.

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.

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.
