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.

Was the C7 Corvette cut from Beyonce's Super Bowl halftime show?

Someone was bound to receive a free 2014 Chevrolet Corvette Stingray during the Super Bowl XLVII festivities; it just wasn't who we thought it was going to be. Despite a report back in December that superstar Beyoncé Knowles would be getting an all-new Corvette during her halftime performance, that turned out not to be the case. Joe Flacco, starting quarterback for the Baltimore Ravens, did in fact win a Corvette for his MVP performance.
So what transpired that prevented Beyoncé from rolling on stage in the new Chevrolet? Anyone who knows isn't telling, but according to Yahoo! Autos, General Motors said that for one reason or another a deal "did not work out," and it appears to have been an eleventh-hour change. Regardless of who's to blame or what prevented this from happening, we're sure Chevy has had no problems getting attention for the C7 Corvette since it was introduced last month.

2014 Chevy Silverado High Country spied wearing trappings of new luxury trim

Spy photographers have spotted the new Chevrolet Silverado High Country and GMC Sierra Denali out on public streets for a little testing. From the looks of things, the Silverado will receive a much-differentiated front fascia along with special badges and those honking 20-inch chrome wheels. Expect to find a more posh interior as well. Likewise, the Sierra Denali will wear a tweaked nose with the familiar Denali bling. The one of the GMC trucks spotted here rolls on 21-inch gunmetal wheels instead of the 20-inch chrome pieces of the High Country.
Word has it both trucks will go on sale after the Texas State Fair this summer. While General Motors hasn't said for certain what we can expect to find under the hood, we'd be surprised to see anything outside of the range of engines found in the standard Silverado and Sierra models. That means buyers should be able to get their hands on the efficient, 23-miles per gallon 5.3-liter V8.
