First privately owned Corvette Stingray blitzes 1/4 mile in 12.23 at 114.88 mph

Chevrolet's latest road rocket, the Corvette Stingray, is a very quick car. If one needs further proof of that, we recommend they take a look at this video from Hennessey of what is claimed to be the first privately owned C7 Corvette to make a pass down the quarter mile. Not just any quarter mile, mind, this black C7 blitzed its way down the tuner's primary testing dragstrip. The Chevrolet ran the quarter in just 12.23 seconds at 114.88 miles per hour. That is a very quick time for a stock car.
Equipped with the Z51 package and a six-speed automatic transmission, not only does the C7 run a solid time, but it does so with little to no drama. That won't last though, as Hennessey will likely return it to its owner with far more power - we just hope they show a drag run of the completed product. Take a look below to watch the C7's 12.23-second run on video.

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.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
