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.

eBay Find of the Day: 1990 Chevy 1500 454 SS with just 7 miles

When trawling the classifieds either on a buying mission or merely a time-wasting mission, we spend a lot of time poring over photographs comparing the seller's idea of "Like New!" with our idea of it. It's hard to argue with seven original miles on the odometer, though, which is what this 1990 Chevrolet 1500 454 SS has. It's being sold by Country Chevrolet on eBay, the same dealer who sold the truck to its one and only owner 25 years ago. The purchaser bought two of them and left this one in a garage under a car cover, said garage being less than seven miles away from the showroom floor. Better yet, you can buy with confidence because the seller "has collected all records," which we expect would be the slimmest manilla folder in the history of receipt-keeping. For those unfamiliar, the 454 SS was a half-ton, regular cab, 2WD pickup powered by a 454 cubic inch (7.4-liter) V8 with 230 horsepower and 385 pound-feet of torque shifting through a three-speed transmission. This was at the same time the Chevrolet Corvette used a 5.7-liter V8 producing 250 hp and 350 lb-ft. The pickup rode on exclusive wheels and only came in black with red cloth inside. The only extra-cost option on this example is an $18 locking fuel filler cap, which, according to the 454ss forum, means it should have cost about $18,460 out the door, the equivalent of about $34,000 today. At the time of writing there are zero bids, but proceedings open at $45,000 and Country Chevrolet wants $49,000 if you have to have your time capsule right now.

1983 Motorweek showdown pits Porsche 928S vs. Chevy Camaro Z28

Last month, Motor Trend threw the Camaro Z/28 and Porsche 911 GT3 into the bear pit and let them fight it out. Way back in 1983, MotorWeek had the same idea, comparing the Camaro Z/28 to the Porsche 928S. At the time, the Camaro was America's best selling sports coupe, the 928S was Porsche's top-of-the-line model that also had the highest top speed of any car sold here. And the price differential was even more stark then: $13,600 for the Camaro, $45,000 for the Porsche. That put the Z/28's cast-iron, 5.0-liter V8 with 190 horsepower and 240 pound-feet of torque against the all-aluminum 4.7-liter V8 with 234 hp and 263 lb-ft in the 928S. Even with that and the Camaro being 14 inches longer than the Porsche, the American was a surprising 40 pounds lighter than the German. The show took them to Summit Point Raceway in West Virginia to see how close a relative performance bargain could hang with a the German GT. Both had five-speed manual transmissions, but the high-speed corners and tight sections of Summit Point would test other handling variables, including the "bone-rattling" Camaro's solid rear axle and disc and drum brake setup vis-a-vis the four-wheel disc brakes and independent suspension on the "firm-but-smooth" Porsche. Paradoxically, the larger disparity 22 years ago resulted in a closer result. Check out the video to see how the Summit was won.
