GM puts 3 million miles on hydrogen fuel cell test fleet

Have General Motors' hydrogen fuel-cell vehicles emitted enough water vapor over the past six-plus years to equal the steam coming out of Old Faithful? Not exactly, but GM has released a few figures related to the Project Driveway initiative it began in 2007. The numbers are impressive, if not quite of the geyser-spouting variety. In all, the General converted 119 Chevrolet Equinox SUVs to run on hydrogen, and those vehicles have just collectively surpassed the 3 million mile mark. And if you were waiting for us to tell you that the distance equals a half-dozen round trips between the earth and the moon, well, there you go. The better news is that the SUVs have combined to save almost 158,000 gallons worth of gas, and some of the vehicles have more than 120,000 miles on them. More than 5,000 drivers have participated in the project. GM reached that landmark about 10 months after it announced that it was working with Honda to accelerate the development of hydrogen fuel-cell powertrain technology. The two companies estimated last summer that it may have something to sell to the public as soon as 2020. For now, you can check out General Motors' press release below. GM Fuel Cell Fleet Tops 3 Million Miles Chevrolet Equinox fuel cell vehicles driven in real world reach milestone DETROIT – General Motors' fleet of fuel cell vehicles recently passed 3 million miles of hydrogen-powered, real-world driving. Some individual vehicles have accumulated more than 120,000 miles. By GM's estimate, using hydrogen to power these vehicles, the fleet has avoided 157,894 gallons of gasoline consumption. This specially equipped fleet of Chevrolet Equinox Fuel Cell vehicles are part of GM's 119-vehicle Project Driveway program, which launched in 2007. Since then, more than 5,000 drivers have provided feedback on the functionality and drivability of fuel cell technology. "Hydrogen fuel cell technology is an important part of GM's advanced propulsion portfolio and we continue to make substantial progress in furthering this technology," said Charlie Freese, executive director of GM's global fuel cell engineering activities. "These vehicles have operated through seven full winters and a wide range of environmental conditions, proving that fuel cells can meet the demands of real-world drivers." Last year, GM announced two fuel cell-related collaborations.

Chevrolet Colorado ZR2 concept suggests a diesel off-road future

"It takes the Colorado to a whole new place." – Mark Reuss The Chevrolet Colorado looks set to gain a more capable off-road version, with the company previewing a potential design direction with a ruggedized concept Wednesday at the Los Angeles Auto Show. Called the Colorado ZR2, the concept brings back the name used on off-road-tuned S-10 and Blazer models in the 1990s and 2000s. The ZR2 has a track that's four inches wider than the Colorado Z71, which is currently the line's most capable off-roader. The ZR2 is fitted with a new grille, power-dome hood, custom wheel flares and off-road-style fascia that reduces overhang and has flip-out aluminum tow hooks. It's all slathered in an outdoorsy hue dubbed Cyprus Green. The are electronic locking front and rear differentials, skid plates and mono-tube coilover shock absorbers. It all rolls (or crawls) on 275/65R18 off-road tires wrapped around custom 18-inch aluminum wheels. There's also a spare tire assembly mounted in the bed, which has a spray-in liner and 48-inch lift jack should things go afoul on the trail. "It takes the Colorado to a whole new place," Mark Reuss, General Motors executive vice president of global product development, said at the reveal. Power comes from the 2.8-liter Duramax diesel engine making 181 horsepower and 369 pound-feet of torque. This engine will arrive later in the year in the production Colorado. While the ZR2 remains only a concept, it suggests a new path for the Colorado – one we hope Chevy decides to take. Chevrolet Introduces Colorado ZR2 Concept Aggressively styled, more capable and driven by new 2.8L Duramax diesel engine LOS ANGELES – Chevrolet today introduced the Colorado ZR2 concept – a vision of how Chevrolet could take the all-new midsize truck's off-road capability to the next level. It also showcases the new 2.8L Duramax diesel engine that will arrive in the Colorado lineup later next year. The aggressively styled concept builds on the capabilities of the production Colorado Z71 and advances the legacy of Chevrolet's previous ZR2 production models. "From the bold stance to the trail-ready special equipment, the Colorado ZR2 is all about the fun of driving where the pavement ends – and doing it in characteristic Chevy style," said Tony Johnson, Colorado marketing manager.

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.
