Aston Martin One-77 edges closer to production

According to Chris Porritt, the One-77's project manager, Aston Martin are hoping to fine tune the car before it enters production next year. Performance is expected to rival the likes of the Chevrolet Corvette ZR1 and the Nissan GT-R, both of which can tackle the 'Ring in around 7 minutes and 26 seconds.

The prototype One-77 uses a highly modified version of the 6.0 litre V12 engines that are found in the DBS, DB9 and V12 Vantage models. Engineers were tasked to take the engine as far as it could go, both in terms of output and weight reduction. Incredibly, the Aston Martin and Cosworth engineers who worked on the powertrain achieved a mass reduction of some 25% while increasing displacement to 7.3L, achieving a power output of no less than 700bhp.

With a projected weight of 1,500kg the prototype One-77 is said to be capable of a top speed of more than 320km/h, while accelerating from 0-100km/h in 3.5 seconds.
