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.

2015 Chevy Volt gets larger battery, though range remains the same

The Chevrolet Volt isn't changing much for the 2015 model year. According to specifications uncovered by Inside EVs, though, the new Volt's battery does have a slightly larger capacity. According to the spec sheet, this doesn't translate to increased range. Real world driving, though, might tell a different story. The 2015 Volt's battery storage is slightly higher than the outgoing model's, up from 16.5 kilowatt-hours to 17.1 kWh. According to GM's manager of electrification technology communications, Kevin Kelly, speaking to Green Car Reports, the increased capacity is "a late change done in the cell... just another continuous improvement to surprise and delight our customers." The stated electric range, however, stays at 38 miles. Inside EVs followed up on its original report, and found that drivers could see some advantage to the battery tweak. When they spoke to Kelly, he told them, "As a result of this change, we would expect that some customers may see a slight improvement in overall EV range." It's worth noting that when battery capacity increased from 16 kWh to 16.5 kWh for the 2013 Volt, electric range increased by three miles to the current 38, while MPGe went from 94 to 98. The price of the 2015 Chevrolet Volt remains steady, at $34,995. The actual cost to the customer is considerably less with the $7,500 federal tax credit, as well as any local incentives.
