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.

Motor Trend puts Chevy Camaro Z28 and Porsche 911 GT3 Head 2 Head

Motor Trend admits, "This is an unfair comparison." But that doesn't make it any less fun to watch when they pit a Camaro Z/28 against the Porsche 911 GT3. The former has a 7.0-liter V8 with 505 horsepower and 481 pound-feet of torque shifted through a six-speed manual. The latter has a 3.8-liter flat-six with 475 hp and 324 lb-ft shifted through a seven-speed dual-clutch transmission. Yet those are only the little disparities – the big disparities are mass and money: the Camaro weighs 3,882 pounds and costs $76,150 as-tested, the Porsche weighs 3,267 pounds and costs $145,785. But they're both about hardcore performance, so MT takes them out on the street, to the drag strip, to the parking lot for figure eights and a skidpad test, and finally to Big Willow for Randy Pobst to give his professional assessment. Remember when a lotta people spent a lotta time debating Pirates vs. Ninjas? This is like that, only it's the "haul-ass good-time car" vs. the "track surgeon." Enjoy the debate in the video.

Nissan Leaf sales double Chevy Volt to close out winning 2014

To close out the year, sales of the two most-popular plug-in vehicles in the US kept going in the direction that they had been all year. The Chevy Volt dropped and the Nissan Leaf had another record month. Sound familiar? The Volt sold 1,490 units in December, a year-to-year drop of 37.7 percent. For all of 2014, Volt sales were down 18.6 percent to just 18,805 (from 23,094 in 2013). On the Nissan side of the ledger, the Leaf sold 3,102 units, up 22.7 percent from the 2,529 sold in December 2013. For the year, Nissan sold 30,200 Leafs, up 33.6 percent from the 22,610 sold in 2013. A few other things to note: For every month in 2014, the Leaf sold more than it did for the same month in 2013. For the Volt, this was only true for three months (April, May and July). Funnily enough, the Volt sold exactly 1,478 units in both March 2013 and 2014. The Volt's 2014 total was lower than both 2013 and 2012, while the Leaf had its best year ever. There were three months in 2014 when people bought at least twice as many Leafs than bought a Volt (September, November, December). The Leaf outsold the Volt every month in 2014. The closest gap was 215 units, in February. The biggest was 1,612, in December. As you've most likely seen, GM is still busy teasing the new Volt, which will make its official debut at the Detroit Auto Show next week. We'll have a more in-depth green car sales post up soon. <iframe embedded="true" "="" scrolling="no" src="https://docs.google.com/spreadsheets/d/1oIuH75vaSHaaplD4x6gLsYjSsiN4oGmez1T63eaYdhY/pubhtml?widget=true&headers=false" height="430"> Nissan celebrates 30,000 leaf sales in 2014, best year ever for sales of any plug-in vehicle NASHVILLE, Tenn. (Jan. 5, 2015) – Nissan, the world leader in electric vehicle sales, shattered yet another sales record with 30,200 LEAF vehicles sold in 2014, which is the first time any plug-in has sold more than 30,000 units in a single year. "Now in its fifth model year, Nissan LEAF is more popular than ever and continues to bring new buyers to Nissan," said Brendan Jones, director, Nissan Electric Vehicle Sales and Infrastructure. "From the beginning our vision was to bring electric vehicles to the mass market in a practical and fun-to-drive package, which is what makes Nissan LEAF the best-selling electric car in the world." Last month, Nissan sold 3,102 all-electric LEAFs, up 22.7 percent from the prior year and a December record.
