You can drive it on the road. But the Aston Martin Vantage GT3 was built for the track. At its heart is a new version of the company's 6.0-litre V12 engine pumping out nearly 600 hp, which is more than enough to power the lower, wider body down the straightaway. Curb weight is down over 200 lbs thanks in part to the liberal use of carbon fiber, which can be found in the center stack, the seats, the bonnet, the door casings, the roof, the front splitter, the front wings, and the unmistakable rear wing. Limited to 100 examples.
