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.

Cadillac XT4 crossover to be built in Kansas City

Cadillac's upcoming XT4, a crossover we've previously known as the XT3 in a long series of spy shots of heavily camouflaged mules, will be built at General Motors' assembly plant in Kansas City on the same platform as the Chevrolet Malibu, Bloomberg reports, citing people familiar with the plan. That will give Cadillac another entry in the red-hot luxury crossover segment and, GM hopes, help to reverse a sales slump in the U.S. It'll also breath life into the Kansas City plant that makes the slow-selling Malibu, where GM cut a third shift last year, by sharing the assembly line between the crossover and sedan and defraying costs for each vehicle. The XT4 was known most recently as the XT3, with styling cues based on the Escala concept sedan from 2016. It's slightly smaller than the XT5, Cadillac's top-selling vehicle, and will also augment the full-size Escalade in Cadillac's stable of SUVs when it makes its expected debut later this year. Cadillac last week reported its second-highest-ever sales mark with 356,467 vehicles, an increase of 15.5 percent over 2016. But that mark papers over an 8 percent sales decline in the U.S. to 156,440 vehicles. The luxury brand is on a hot streak in China, where sales jumped 50.8 percent last year to 175,489 units.Related Video: Image Credit: Brian Williams Plants/Manufacturing Cadillac Chevrolet GM Crossover sales cadillac xt5 cadillac xt4 cadillac xt3

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
