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

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
If you have about five minutes and you can't get enough information about the new 'Vette, then check out the videos posted below.

The Volt Dance had precedent; meet the Chevy Footlockers

Marketing in the auto industry can get weird sometimes – really quite bizarre, in fact. For example, remember the Chevy Volt dance from the 2009 Los Angles Auto Show? If not, a group boogied to a song about the electric car, and it was every bit as awkward (and hilarious) as that sounds. In fact, that innocent bit of promotion lives in infamy, as some pundits grabbed hold of it during General Motors' bailout and asked why America's tax dollars were going to such things. The Chicago Auto Show has been digging through its vault of vintage videos, and it has come up with something that might actually be worse than that Volt-themed routine. They're called the Chevy Footlockers, and they're a dance troupe somehow promoting the Cavalier at the 1988 Chicago show. The connection between the car and their routine is unclear, but it's gloriously cheesy in a Chippendales-meets-AC Slater sort of way. Also, there are props towards the end, but we aren't going to spoil them for you, because you just have to watch for yourself. As a bonus, there's another (brief) clip below showing a female dance group with the Geo Tracker at the '91 Chicago show, and they sing, too. Scroll down to watch both of these oddities.
