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.

GMC Envoy could be returning as GM files for 'Envoy' trademark

The GMC Envoy could be on its way back, if a recent GM trademark filing is any indication of the future. To be exact, GM's trademark filing is for the name "Envoy," and is applicable to "motor vehicles, namely, sport utility vehicles, engines therefor and structural parts thereof." A victim of the recession and high gas prices, the original Envoy – related to the Blazer, and more recently the TrailBlazer and similar GM SUVs – was discontinued after the 2009 model year. In today's SUV-happy market of low gas prices, unearthing the somewhat familiar Envoy name makes a certain amount of sense. As soon as gas prices start trending in the other direction, we'll all be saying the opposite, though. What this SUV will take shape as is the big question now. With the Chevrolet Blazer well and truly on its way, there's every reason for a GMC version of Chevy's stylish new crossover sporting the Envoy name. Another, less likely, possibility is a Traverse-sized vehicle to slot between the shorter Acadia (10 inches shorter than the Chevy Traverse) and the body-on-frame Yukon. GM could come out of left field and make the Envoy a Buick too. It fits the bill with the "En" beginning, and Buick undoubtedly has crossovers in the works. We think that's even more unlikely, but it's important to remember that we're still in the speculation phase. Soon we'll drive Chevy's new Blazer, and perhaps have more news then. Check in next week for that. Related video:
