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

Chevy Silverado edges Ram 1500 in Consumer Reports two-truck shootout

Forget Corvette versus Viper. When it comes to important head-to-head comparisons, fullsize trucks are where domestic automakers really care. And until the redesigned Ford F-150 makes its debut, the Chevrolet Silverado is going to have plenty to brag about thanks to a new Consumer Reports shootout against the Ram 1500.
It was a tight race among these V8-powered titans, but the all-new 2014 Silverado (and its GMC Sierra twin) barely edged out Ram's updated pickup with a score of 81 points - enough to make it the institute's top-rated fullsize truck on the market. Its narrow victory over the Ram, which finished just three points back, was due to its superior fuel economy, better towing and payload capacity and conveniences like a lower step-in height, easy-to-use tailgate and rear bumper steps that make loading and unloading less of a chore.
Importantly, CR notes that buyers with less heavy-duty truck needs might actually prefer the Ram over the Chevrolet, since its high points include a smoother ride thanks to its coil spring rear suspension, dominant infotainment system with Uconnect, and a big thumbs up for the available Hemi engine and eight-speed automatic transmission.

2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.
