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.

Nissan sells 3,117 Leaf EVs in May, climbs over 3,000 for first time ever

Chalk up a big win for the Nissan Leaf. In May, the world's most popular electric vehicle sold a record 3,117 units, the first time any pure electric vehicle has sold over 3,000 units in a month in the US (unless Tesla managed that feat but rolled the number into a quarterly report). This marks the 15th month in a row of record Leaf sales and the seventh where the Leaf was the top EV seller in the US. The challenge bar is set for someone to step up to compete with this all-electric wunderkind. Chevrolet did sell over 3,000 Volts once, in August 2013. The Leaf's one long-standing competitor, of a sort, is the Chevy Volt, which used to regularly outsell the Leaf but moved only 1,684 units in May. That's still an increase of 4.8 percent over 2013 but is part of a 4.5 percent decline in year-to-date Volt sales for 2014 compared to last year. The last time the Volt outsold the Leaf was October 2013. Chevrolet did sell over 3,000 Volts once, when it moved 3,351 in August 2013. Let's take another look at those 3,117 Leafs sold last month. They represent a 45.8 percent increase over May 2013, when 2,138 Leaf EVs were sold, so someone is doing something right in Japan and Tennessee. So far, Leaf sales in the US are up 36.4 percent year-to-date, to 10,389 EVs. That's just under half of the 2013 total, and it was accomplished in five months. In 2013, Nissan sold a total of 22,610 Leafs. Anyone want to hazard a guess where the total will be at the end of the year? As always, we'll have our detailed monthly sales write-up including other plug-in vehicles as well as hybrids and diesel car, up soon. For now, though, the big news is big Leaf sales. Read Nissan's press release below. Nissan Group reports May 2014 U.S. sales May 2014 May 2013 % Change Nissan Group Total sales (units) 135,934 114,457 +18.8 Nissan Division May sales 125,558 106,558 +17.8 Infiniti May sales* 10,376 7,899 +31.4 NASHVILLE, Tenn. – Nissan Group today announced total U.S. sales for May 2014 of 135,934 units, an increase of 18.8 percent over the prior year and a May record. Nissan highlights: Nissan Division set a May record at 125,558 sales in the month, an increase of 17.8 percent. This marks a monthly record for Nissan division in 14 of the last 15 months. May was the best-ever month for Nissan LEAF with 3,117 sales, an increase of 45.8 percent over the prior year. In May, LEAF passed 50,000 total U.S. sales since launch, further establishing it as the leader among electric vehicles.

Chevy Spark EV could be coming to Midwest later this year

Ohio is not known as a hotbed of EV sales – if anything, the state is a bit anti-EV, thanks to a legislative fight against Tesla's direct sales model – but it might be on Chevrolet's short list to expand the market for the Spark EV in the near future. The latest official GM press release on the battery-powered Spark still says the car is "available exclusively in California and Oregon," but Hybrid Cars found four Ohio dealerships that list a Spark EV on their websites, with hints the the car will be coming to the Midwest state by the end of the summer. See, for example, here, here, here and here. But that's probably not going to happen, according to Randy Fox, GM communication's manager for passenger cars. Fox told AutoblogGreen that, "At this point in time, we don't have any official plans to expand the Spark EV beyond California and Oregon." The reason is that California and Oregon have the infrastructure to support EVs, Fox said, and GM wants to be able to support its EV customers. "We are continuing to look at other options," he said. "The selling point for electric cars today is not advertising, it's eyeballs, it's peer exposure" – John O'Dell John O'Dell, a senior editor at Edmunds.com, told AutoblogGreen that, "It makes sense for [GM] to expand sales and it makes sense to do it in a quiet manner, to get these vehicles on the road. The selling point for electric cars today is not advertising, it's eyeballs, it's peer exposure. If someone in my neighborhood has one and he likes it, then maybe I can trust him. So it's important to get these vehicles on the road." Chevy sold 182 Spark EVs last month, a significant increase over the 98 sold in April. That's still small potatoes compared to the 3,000+ Nissan Leaf EVs sold last month, but making the electric Spark available in Ohio, say, or GM's home state of Michigan could boost those numbers. AutoblogGreen called a few dealerships in Michigan to see what they had heard. One salesman said he didn't think GM had started production yet but the inventory manager for another dealership said the Spark EV is scheduled to arrive in the Midwest in "roughly the fourth quarter." What would GM's incentive be to offer the car in markets outside of California where it can gain ZEV credits with each sale?
