What you're looking at is the new Aston Martin Vantage GT3 Special Edition. As you might have guessed, it's based on the Vantage that first arrived a decade ago, but has come a long way by now: where the original packed a 4.3-liter V8 with just 380 horsepower, the GT3 goes with Aston's long-serving 6.0-liter V12 tuned to 592 horsepower. That's more powerful than anything this side of the One-77.
Of course Aston didn't just toy with the engine and then head to the pub. It also replaced many of the body panels with carbon fiber and junked anything extraneous to cut the curb weight by 220 pounds (compared to the V12 Vantage S), fitted it with a more aggressive aero package and mounted semi-slick tires on a wider track.
Only 100 examples will be offered, so if you're not on the list, the closest you're likely to get is in the slideshow of live images from the floor of the Geneva Palexpo.
