Aston Martin's Project Vantage concept car will not go into production, said Aston Chairman Bob Dover.
He said the vehicle, which made its world debut in Detroit, is a test bed for new technologies.
The $2.5 million project involved engineers and designers at Aston Martin, Ford Advanced Vehicle Technology, Borg Warner, Magneti Marelli, AP Racing, ITT and TRW.
The two-seater can run at more than 320kph, with a 0-96kph time of only four seconds. It can achieve 225kph at 400 meters.
But for all its performance, Aston's parent company Ford says the Project Vantage still consumes just 12 liters per 100km.
The engine is an aluminum, 48-valve, 6.0-liter V-12. It uses the architecture from Ford's modular V-6 program.
Project Vantage has a twin-skinned carbon fiber roof, and a combination of extruded aluminum and aluminum honeycomb body.
It is half the weight and double the rigidity of a conventional Aston sports car.
Racing technology is used on the suspension and in the driver's seat. The Project Vantage uses steering wheel mounted shift paddles to change gears.
