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.

What car should James Robertson buy to drive his famous 21-mile commute?

The Internet has been abuzz this week with the story of Detroit resident James Robertson, the 56-year-old factory worker who has walked some 21 miles to work for the last 10 years. The Detroit Free Press brought Robertson's story to the fore, helping an online fundraising campaign to generate more than $275,000 (as of this writing). The original goal was just $5,000, or about enough to replace the used Honda that died on Robertson back in 2005, and left him walking. So, newly flush with funds, what's the perfect car for Robertson to buy? Let's look at the specifics of his situation, and try to pick out the best options. Here's what we know: Robertson's commute is (famously) 21 miles; he lives in downtown Detroit (for now) and seems pretty humble, so something very flashy is probably out; former Honda aside, his ties to the city (and statements about being a Ford fan) seem to indicate a Detroit Three company product is best; he's a single guy with a girlfriend; he's got to deal with Michigan weather, and the sometimes fickle snow removal processes in The D. Here are some choices: Ford F-150 Robertson is on record as being a Taurus fan, and after a decade of walking I've no doubt that the big sedan would offer a cozy respite. Still, as a car guy and a student of the industry, I'd have a hard time recommending a sedan so clearly in need of replacement. Especially when The Blue Oval has such great stuff within the rest of its roster. The 2015 F-150 seems almost perfect for Robertson. Opting for either of the new EcoBoost V6 engines should help keep fuel bills in reasonable check, while healthy ride height and four-wheel drive will get him to work on time even during the snowiest of snow days. Better still, with a fat options sheet and car-like ride quality, Robertson can have just about every amenity he might want, in a package that won't disrespect his blue-collar roots. Chevrolet Colorado You guys saw this one coming, right? The smaller footprint of the midsize Chevy pickup, relative to some of the other options here, should be an advantage for urban parking and driving. And again, 4x4 is an option for the nasty weather, the running costs should stay pretty low and there aren't many tech/luxury features that can't be had in-cabin. I'd go ahead and splash out on the Crew Cab bodystyle, too, just in case Robertson feels like starting a carpool.
