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.

Watch this week's Top Gear America used-car challenge

Top Gear America is back for the penultimate episode of the first season. Used car challenges were some of the highlights of the original UK edition. In our exclusive clip, Tom Ford, Antron Brown and William Fichtner run their $7,000 sports cars in a drag race. As expected, the trio chose very different cars for the challenge. Watch the video to see if a Subaru WRX's all-wheel drive can overcome a power deficit to beat a Ford Mustang and a Chevy Corvette. Brown and Fichtner also spend some time relaxing with an old Jeep Wagoneer. Like them, we're really hoping Jeep will bring back the Wagoneer nameplate. Brown also drives a Maserati Levante, proving that not all family cars need be boring. This week's guest star is actor, rapper and former host of Pimp My Ride, Xzibit. Top Gear America airs Sundays at 8 p.m. Eastern on BBC America. Related Video: Celebrities TV/Movies Chevrolet Ford Subaru Top Gear exclusive top gear america

It seems General Motors can't go more than a few weeks without issuing a major recall. Since the initial ignition lock recall on February 10, over 25 million vehicles have been recalled for defects. We used the National Highway Traffic Safety Administration recall list to compile a snapshot of all the GM vehicles recalled in the last two months. NHTSA also provides a search engine that allows owners to search for recalls on their vehicle. An automotive company must do everything in their power to notify its customers when a recall is issued on a vehicle. If you own any of the following vehicles and you have questions regarding your car, you can contact Chevrolet at 1-866-694-6546, GMC at 1-866-996-9463, Buick at 1-800-521-7300 and Cadillac at 1-866-982-2339. Or check out General Motor's recall site. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153) or go to www.safercar.gov. Here's a brief summery of the other vehicles currently under recall: July 26 – 414,333 cars affected NHTSA Campaign Number: 14V447000 Models under recall: Certain model year 2011-2012 Buick LaCrosse, Regal and Chevrolet Camaro, as well as certain 2010-2012 Cadillac SRX, Chevrolet Equinox and GMC Terrain vehicles, equipped with power height adjustable driver and passenger seats. Problem: In the affected vehicles, the bolt that secures the driver's and passenger's power front seat height adjuster may fall out causing the seat to drop suddenly to the lowest vertical position. Consequence: If the driver's seat unexpectedly drops, the distraction and altered seat position may affect the drivers' control of the vehicle, increasing the risk of a crash. Solution: Dealers will replace the height adjuster shoulder bolts, free of charge. July 14 – 16,939 cars affected NHTSA Campaign Number: 14V341000 Models under recall: Certain model year 2011 Cadillac CTS vehicles manufactured October 18, 2010, to June 2, 2011. Problem: In the affected vehicles, vibrations from the drive shaft may cause the vehicle's roll over sensor to command the roof rail air bags to deploy. Consequence: If the roof rail air bags deploy unexpectedly, there is an increased risk of crash and injury to the occupants.
