GM natural gas-powered vans recalled due to possible leak

General Motors is recalling almost 3,200 of its compressed-natural-gas powered utility vans because of possible leaks. GM and the National Highway Traffic Safety Administration (NHTSA) released a notice last week saying that 3,196 Chevrolet Express and GMC Savana CNG vans are on recall, though no accidents have been reported due to the possible issue. The recall is specifically for vans for model years ranging from 2011 to 2014. The recall stems from a potential leak from the compressed natural gas high-pressure regulator, and such a leak could cause a fire or explosion. GM will replace the vehicles' high-pressure regulator in order to fix the problem, will do it free of charge and is instructing owners to contact Chevrolet or GMC customer service to arrange for the parts replacement. Utility vehicle makers like General Motors have pushed for fleet sales of CNG-powered vans and trucks for the past few years and have touted them for their cheaper refueling costs relative to standard gasoline, not to mention the fact that natural gas can be readily sourced from throughout North America (thanks, fracking). According to CNGPrices.com, compressed natural gas sells for about $2.22 a gallon, on average, while the AAA is pegging the average price of gas at $3.34 a gallon. NHTSA has posted information on the recall here. Featured Gallery News Source: NHTSA via Reuters Green Chevrolet GM GMC Natural Gas Vehicles CNG gmc savana

EcoCar2 is on the hunt for a better, cleaner Chevy Malibu [w/video]

The students spent three years transforming an ordinary Chevy Malibu into a revolutionary vehicle. Not far from the building where General Motors once invented the Chevy Volt, a dozen or so college students are standing on the blacktop alongside a test track, watching a professional driver push the limits of a plug-in hybrid car they've built that's far more radical. These students, from Colorado State University, have spent the past three years transforming an ordinary Chevy Malibu into a revolutionary vehicle. At first glance, it still looks like a regular sedan. But under the hood, they've installed a hybrid powertrain that contains both hydrogen and electric power sources. Even by the standards of the Department of Energy competition they're participating in, it's an outlier. That's exactly what they had in mind. "We didn't want to come here and tell them how to build a better Volt," said Tom Bradley, faculty adviser for the Colorado State team. "They already know how to do that. We can tell them how to think about these possibilities in a whole new way." After three years of work, it all comes down to this. The Colorado State team was one of 15 that came to GM's Milford Proving Grounds last week for the final stretch of the EcoCar2 competition, which challenges regular college students who have no automotive experience to do nothing less than reinvent the American car. The teams have come from across North America, and include schools like Ohio State and Virginia Tech that have a long history of participating in similar competitions, and schools like the University of Washington and Embry-Riddle Aeronautical University that are here for the first time. After three years of work, it all comes down to this. The teams have operated 24 hours a day for almost two weeks here at the Proving Grounds, running a gamut of tests that include a 310-point safety inspection, emissions and energy-consumption tests and road tests, in which professional GM drivers ensure they're road worthy. The winning team will be announced tonight in Washington D.C. Revolutionary cars, ordinary package While other green-car competitions encourage extreme designs, this one comes with a somewhat constraining twist: Yes, students must improve fuel economy and reduce emissions, but in the end, they still have to have a car that would appeal to mainstream customers. In practical terms, that means they must keep conveniences like air conditioning and trunk space.

Chevy up to old EVs-equal-range-anxiety tricks in new Volt Olympics ad

General Motors is at it again with a new Chevrolet Volt TV commercial. Viewers of the Winter Olymics (at least in some markets) recently saw a TV ad in between the skating and the skiing that made no mention of the environmental benefits or freedom from the power of Big Oil that electric vehicles provide. No, this one was based on pure survival instinct. In the video, a father is driving down a highway, perhaps through the Mojave Desert. His young son is sitting in the Volt's backseat and asks what happens when the EV's battery runs out. "We'll have to cross that burning desert with snakes and cactus until we make it back to civilization," the dad tells his son as they pass the skeleton of a fallen bull. The fine print makes it clear that the actual maximum range is 342 miles. But there is hope. The father tells his son, with a beaming smile on his face, that the gas generator has kicked in and they're going to make it through the desert. As they wend their way to the horizon, a voice over says that Volt drivers who charge up regularly are making it 900 miles between fill ups. The fine print makes it clear that the actual official maximum range before you need to either plug in or fill up is 342 miles. This theme that emphasized range anxiety has been utilized by GM since the extended range Volt was launched in late 2010, despite the fact that Chevrolet now offers an all-electric vehicle in the Spark EV. Volt fans are praising the commercial, called The New Freedom, on the GM-Volt forum and you can see for yourself below. This content is hosted by a third party.
