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.

Watch NASCAR racer Jeff Gordon put one over on a used car dealer... sorta

Full Disclosure: in my younger days, I loved nothing more than tormenting passengers with my behind-the-wheel hijinks. Once, after a particularly artful handbrake turn on a two-lane at around 50 miles per hour, I left one backseat occupant crying in their own lap. This isn't necessarily something to be proud of, but it gives you a glimpse into why it is that I find this ad from Pepsi so damn disappointing. The premise is beautiful. Take NASCAR legend Jeff Gordon, give him a disguise and set him loose upon some unsuspecting used car dealer. Hilarity ensues.
Except that this Pepsi Max commercial is so obviously staged, it can't help but feel like some ham-fisted marketing fail. From the strategically placed aftermarket cupholder mounted mid-dash for the hidden camera to the fact that the supposed dealer Camaro is displayed as a 2009 model (Hint: Chevrolet didn't make any), this clip is about as organic as a Twinkie. Still, we would never turn down a chance to watch Gordon thrash on a rental-spec coupe - only problem is, he probably didn't even do the driving himself. Check it out below.

GM 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.
