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.

Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

2014 Chevy Cruze Diesel arrives with 42 mpg for $25,695*

The last time General Motors had a diesel passenger car in the US, it was the 1.8-liter 1986 Chevette. At the 2013 Chicago Auto Show today, GM is unveiling the much-anticipated 2014 Chevrolet Cruze Diesel. The compact bows with a 2.0-liter turbo-diesel four-cylinder engine that boasts 148 horsepower and 258 pound-feet of torque, with full twist coming on at just 2,000 rpm. What's more, the common-rail, direct-injection diesel features an overboost function that allows the engine to deliver up to 280 lb-ft of torque for 10 seconds at a time. Even with 10 more horsepower and 110 more pound-feet of torque than the available turbocharged 1.4-liter four-cylinder in the Cruze, the 2.0-liter diesel engine can return up to 42 mpg (highway) bolted to its six-speed automatic transmission.
If you're counting, that figure meets the less powerful Cruze Eco with a six-speed manual transmission. More importantly, the auto transmission Cruze Diesel matches its main competition, the Volkswagen Jetta TDI, in highway fuel economy. The Cruze 2.0 TD (as it will be badged) can also handle up to 20 percent biodiesel (B20), whereas the Jetta is rated only for B5. General Motors has not released city fuel economy for its newest diesel, but we do know how much it will cost you to jump behind the driver's seat.
GM will kindly ask for $25,695, plus an $810 destination fee. That marks a $2,115 premium over a loaded Cruze LTZ Auto and $2,640 more than the Jetta TDI, though the MSRP will net you a leather interior, 17-inch alloy wheels and an Aero Performance Package, as well as a two-year maintenance plan and five-year, 100,000-mile powertrain warranty. Compared to the gas-powered Cruze, you also lose a couple cubic feet of rear cargo space thanks to a 17-liter diesel emission fluid tank. That urea fluid, which helps put the clean in clean diesel, will need to be refilled at least every 10,000 miles.
