Just 150 examples of the GT8 will be built.

Aston Martin has unveiled a limited-edition version of the V8 Vantage developed with track use in mind.Called GT8, the more hardcore Vantage is powered by a naturally-aspirated 4.7-liter V8 engine that makes 446 horsepower, about 25 more than the regular Vantage it's based on. A six-speed manual transmission comes standard, and a seven-speed automated-manual unit controlled by shift paddles is offered at an extra cost. Aston hasn't published performance specifications yet.

The GT8 is up to 220 pounds lighter than the regular Vantage thanks to a lithium-ion battery and the widespread use of carbon fiber. Buyers who want an even lighter car can pay extra for polycarbonate rear windows, a titanium exhaust system, and a roof panel crafted out of carbon fiber. Visually, Aston's newest limited-edition model receives a full body kit that includes a splitter up front, fender flares, and a rear air diffuser. The trunk-mounted wing shown in Aston's press shot is part of the optional Aero Pack.

The cabin is fitted with carbon fiber door panels and bucket seats, but it's not as stripped-out as you might expect. It retains creature comforts such as A/C, a 160-watt sound system, and the latest generation of Aston's AMi III infotainment system.

The Aston Martin Vantage GT8 is on sale now with a base price of £165,000, a sum that converts to roughly $235,000. Production is limited to just 150 examples, and not a single one will be shipped to the United States.
