2019 Chevrolet Silverado High Country
The all-new 2019 Chevrolet Silverado 1500 pickup is lighter, more tech-laden, and a bit more aggressively styled but doesn’t look radically different than the previous versions. There are four new grille designs depending on the model. It comes in eight trim levels that include the high value Work Truck, Custom, and Custom Trailboss; the high-volume LT, RST, and LT Trailboss; and high feature LTZ and High Country. There are Regular, Double, and Crew Cabs; short and long beds, and rear-, four- and all-wheel drive models, depending on trim levels. Interesting aerodynamic touches are included like air curtains that improve efficiency.

Silverado offers plenty of powertrain choices. There’s an all-new 2.7-liter, four-cylinder turbo that features cylinder deactivation and stop/start for efficiency, plus a twin-scroll turbocharger for improved low-end response.  It connects to an eight-speed automatic transmission and delivers an estimated 20 city/23 highway mpg. Rated at 310 horsepower and 348 lb-ft torque, this engine brings the Silverado a 2,280-pound payload rating and maximum tow rating of 7,200 pounds. A new 2.7-liter turbo engine replaces the naturally aspirated 4.3-liter V-6 in the Silverado LT and RST sport-truck. The 4.3-liter V-6 connected to a six-speed automatic transmission remains the base engine in other trim levels. A new 3.0-liter Duramax diesel paired with a 10-speed automatic and a stop-start system is coming in early 2019.

The all-new 2019 Silverado High Country interior features more pFurthering efficiency by an estimated 5 percent is the Silverado’s dynamic fuel management (DFM) technology that enables only those cylinders needed to deliver required power to come into play. DFM features 17 cylinder patterns that constantly determine how many cylinders are used to meet the torque demanded, making this determination 80 times per second to optimize efficiency and power delivery at all speeds. DFM is available on the optional 355-horsepower, 5.3-liter V-8 with an eight-speed automatic and 420-horsepower, 6.2-liter V-8 teamed with a 10-speed automatic. These V-8 engines also feature stop/start.

The Silverado's weight has been reduced by as much as 450 pounds, depending on the model, through the use of varying thicknesses of high-strength steel throughout and aluminum on some body panels. The Silverado offers the all-new Durabed cargo box that’s seven inches wider with greater volume for more hauling capacity. The crew cab’s wheelbase is four inches longer, overall length has increased by about 1.6 inches, and the truck is 1.2 inches wider. There’s also 2.5 inches greater rear-seat legroom. A two-inch suspension lift is a factory option. Pickups are often used for towing and Chevy makes this easier with the Silverado’s Advanced Trailering Package and Trailering Camera Package. A trailering app with theft alert and more is included.

PrintFor 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-i8-award-winner

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.

jeep-grand-cherokee-ecodiesel-winnerThe 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.

ford-f-150-award-winner

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.

2015-green-car-of-the-year-logoOver 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-13-action-rightBMW’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.

bmw-i3-cutawayOffering 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.

bmw-i3-dashAcceleration 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.

bmw-i3-chargingEfficiency 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.

bmw-i3-side-doorsThe 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.

alan-lloydThe 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.

audi-laserlightIlluminating the road ahead is a crucial element in driving. It’s also one that has long benefitted from technological innovation. To this end, Audi celebrates the evolution of automotive lighting with its Sport quattro laserlight concept car. The high performance, two-door, Plasma Red coupe harkens back to the iconic 1983 Sport quattro even as it’s abundant advanced technology and design cues point to the future.

The laserlight concept is named for its future lighting technologies. Two low-profile trapezoidal elements are visible within the headlights. An outer one generates low beam light using matrix LEDs and an aperture mask, while an inner element produces laser light for the high-beam.

audi-laserlight-detail

Laser diodes are significantly smaller than LED diodes, only a few microns in diameter. They can illuminate the road for a distance of nearly 1,640 feet, approximately twice the lighting range with three times the luminosity of LED high beam lights. This technology is finding use in the 2014 R18 e-tron quattro for track duty.

Motivating the laserlight concept is a 4.0-liter, bi-turbo V-8 TSFI (turbo stratified fuel injection) engine and a disc-shaped electric motor located between the engine and transmission. The V-8 produces 560 horsepower and 516 pound-feet torque, with the electric motor contributing an additional 148 horsepower and 295 pound-feet torque. A modified eight-speed Tiptronic transmission is mated to the quattro drivetrain with a sport differential at the rear axle.

 audi-laserlight-instruments

Electrical energy is stored in a 14.1 kilowatt-hour lithium-ion battery, sufficient for 31 miles of all-electric driving. When the V-8 and electric motor are working together, the Audi Sport quattro laserlight concept can accelerates from 0 to 62 mph in 3.7 seconds. Top speed is 189 mph. This impressive performance comes with an equally impressive 94 US mpg fuel economy. This is achieved in part through its electric plug-in operation in addition to a cylinder on demand system that deactivates four cylinders of the V-8 under partial load. Also helping is a start-stop system and several levels of regen braking to enhance driving dynamics.

Drivers can switch between three different modes. In EV mode, just the electric motor operates with sufficient high torque power, even outside the city. The active accelerator pedal indicates the transition by a change in pedal resistance so a driver can intentionally influence the mode selection. The Hybrid mode provides optimal interplay between the V-8 and the electric motor for best fuel-savings, and additionally incorporates environmental and route data. A driver can choose the Hold and Charge modes to ensure sufficient electrical energy is available for electric-only driving at their destination. There are different levels of regenerative braking to enhance the driving experience.

audi-laserlight-console

The laserlight’s multifunction sport steering wheel has buttons to control the hybrid drive, start-stop function, vehicle handling system, and the car’s virtual cockpit. Key information is shown on the large Audi TFT display in high-resolution 3D graphics. A cutting-edge Nvidia Tegra 30 processor handles the graphics.

Nearly all functions can be controlled from the further-developed MMI mounted on the center console. Its large rotary pushbutton, which also serves as a touchpad, can be pushed in four directions. It’s surrounded on three sides by four buttons that control the main menu, submenus, options, and a back function. The intuitive layout is similar to a smart phone with all frequently used functions accessed lightning fast.

Lightweight design plays a major role in the Audi laserlight concept’s dynamic performance. A combination of ultra high-strength steel sheet and structural elements of cast aluminum is used in the occupant cell. The doors and fenders are made of aluminum, with the roof, engine hood, and rear hatch and other components made of carbon fiber reinforced plastic (CFRP). Thus, the concept weighs 4,079 pounds including the weight of the large battery pack.

 

audi-a6-tdi-sideIt’s hard not to wear a broad grin while driving Audi’s 2014 A6 TDI. One of a growing array of upscale TDI models in the Audi stable, the $57,500 A6 TDI presents a compelling case for premium mid-size sedan buyers to go clean diesel. Time behind the wheel illustrates the well-balanced nature of the A6 TDI, which artfully blends luxury, comfort, performance, and efficiency in a very desirable package. Plus, it’s just fun to drive.

The A6 TDI’s 3.0-liter turbocharged direct injection V-6 is surprisingly quiet and smooth, dispensing with the two inherent challenges that diesel as a whole has faced in attracting U.S. buyers in the past. Ride quality, handling, and overall driving characteristics are excellent. The A6 TDI is powerful, with strong low-end torque pressing you back in the seat with ease while delivering 240 hp and an impressive 428 lb-ft torque. All this power is channeled to the highway via an 8-speed tiptronic transmission and quattro all-wheel drive. Acceleration from 0-60 mph is achieved in a quick 5.5 seconds.

audi-a6-tdi

This level of power-at-the-ready does not sacrifice efficiency as one might expect, particularly in highway driving as the model achieves a rather impressive 38 mpg. Total driving range of over 700 miles is possible. The TDI clean diesel’s inherent efficiency is bolstered with other efficiency measures including a relatively lightweight chassis and aluminum body panels, plus a start-stop efficiency system that shuts the engine down under specific conditions such as extended idling or at stoplights. The engine restarts instantly when a driver releases the brake pedal.

Driving performance and efficiency are just part of the story with the Audi A6. This model makes a point of enveloping driver and passengers in a luxurious and accommodating interior, paying great attention to detail throughout the cabin with a curved wraparound dash, fine leather, and high-end materials. Instrumentation and controls are well placed and intuitive.

audi-a6-tdi-cabin

Infotainment and connectivity features are extensive with MMI Navigation plus and Audi connect, which offers Google Earth mapping and in-vehicle Wi-Fi connectivity for up to eight wireless devices. Available are an array of sophisticated features including night vision assistant, heads-up display, and Audi pre sense plus, the latter system helping to detect imminent collisions and initiate protective measures.

The A6 TDI presents a very upscale exterior with sharp lines and unmistakable Audi design cues, among these Audi’s signature LED lighting technology. Add in efficient and responsive TDI power and the package gets even more compelling.

 

carbon-fiberCan cost-efficient carbon fiber be created from renewable, non-food-based feedstocks like agricultural residues and woody biomass? The Department of Energy believes so and is now putting up $12 million in funding to help make it happen. The agency says that carbon fiber created from biomass offers greater environmental benefits than traditional carbon fiber produced from natural gas or petroleum, and also believes it may be less costly to manufacture.

Lightweighting is a growing trend in auto manufacturing as one of many strategies to help create more efficient vehicles. Advanced materials like carbon fiber may play an important role if this material can be created more sustainably and, importantly, more affordably. DOE points out that reducing vehicle weight just 10% can improve fuel economy by 6% to 8%. More information is available at DOE’s Funding Opportunity Exchange website.

About a year ago, I gathered all our employees for a meeting and proceeded to make one bold statement, and an even bolder prediction. I shared my deep conviction that we were at the forefront of a historic opportunity within the automotive, trucking, and transportation industry. My prediction: We were on the verge of experiencing near vertical technological innovations within our industry and the next 10 years would usher in dramatic change. So far, so good!

brian-olsonChange and the rapidity of change are hard to predict, but not so when we can turn to the evidence around us and identify well-defined trends and plausible technological pathways. Never before has society experienced such spectacular innovations within the transportation industry. Just in the past five years, the industry has spiritually ushered in battery powered roadsters, plug-in-hybrids, natural gas powered vehicles, fuel-sipping new engine technologies, and never-before seen intelligent electronics andeighting materials. It is hard to believe companies are actually testing vehicles that will drive by themselves. Unreal! And here is the best part – technological breakthroughs and industry advancements will become even more pronounced. The transportation industry is poised to experience Moore's law of near vertical change. The foundation has been set. Everything can and will be challenged.

Traditional drivetrain technologies and fuels have quickly been put on notice. The internal combustion engine is being re-invented. Gasoline and diesel are no longer the only games in town. New powertrain technologies are multi-faceted and incorporate multiple energy sources. Transcending it all are alternative fuels such as natural gas, which is emerging as the smart choice to an environmentally conscious society, economically driven consumer, and job-creation minded country.

Natural gas vehicles will become as permanent as they will be fashionable. This is very predictable and exciting. Every macro-trend and technological advancement points to accelerated adoption of this cheaper, cleaner, and home-grown fuel to run our vehicles. A new generation of technology advancements enables radical growth and broad-scale adoption of natural gas vehicles - innovative direct-injection and engine technologies, ultra light-weight composite materials and advanced processes, unique adsorbent storage materials, and refueling methodologies never before seen or used. These innovations are setting the foundation for real change – a vertical change.

We can all let our imaginations run wild and dream about the future of automotive technology – but that future is now. We are in the midst of a historic transformation within this industry.

My company, Quantum Technologies, has been a leader in advancing alternative fuel storage technologies over the past two decades, hard at work innovating solutions to store compressed hydrogen at 10,000 psi for fuel cell vehicles or deploying high strength carbon composites for natural gas storage tanks. Case in point, we recently introduced the next generation fuel tanks (Q-Lite™) using ultra-lightweight and lower-cost materials. These advancements are impressive and enabling. While gaseous fuel storage technology has progressed steadily over the past 10 years, advancements over the next five years will be more remarkable. Dramatic change in any industry opens up an abundance of opportunities to shape the future.

The next generation compressed gas fuel storage systems will be defined by advances in materials, high precision manufacturing processes, and optimized topology with built-in diagnostics. Future compressed fuel tanks will be dematerialized, lighter in weight, and volumetrically efficient, storing gases in ways and pressures that were not possible five years ago.

My meeting with the employees was not overly long, but rather direct and pointed. Although they were keenly aware of our company's contribution to these emerging technologies and took pride in reflecting on their own pioneering accomplishments, I finished with one last thought: Companies that are merely reactionary to the technological changes may not survive. Successful companies will need to anticipate the future of change, shape it, and lead it!

Brian Olson is CEO of Quantum Fuel Systems Technologies Worldwide, a company specializing in the development and production of natural gas storage systems and the integration of advanced vehicle control systems and drivetrains.
