Later today in Geneva, Aston Martin will officially unveil the One-77, which represents all the brand has to offer in terms of craftsmanship and engineering. The front-engine, rear-wheel-drive supercar features a very special version of Aston Martin's 6.0L V12 engine that's been tuned by the legendary motor mavens at Cosworth. Enlarged to a full 7.3 liters of displacement, the One-77's V12 is a full 25% lighter than the engine on which it's based while producing in excess of 700 bhp. The One-77 also features a monocoque tub comprised entirely of carbon fiber, which helps keep its curb weight around 3,300 lbs. A unique inboard suspension system, six-speed sequential manual gearbox and carbon ceramic brakes at all four corners are just a few of the top shelf standard features that One-77 customers will be getting. Add it all up and Aston Martin expects a 0-60mph time of just 3.5 seconds and top speed over 200 mph. The One-77 will be the most powerful and fastest Aston Martin ever made and represent the brand's zenith. It'll be tough to top this one, that's for sure. Stay tuned for live pics of the Aston Martin One-77 later today from the floor of the Geneva Motor Show.
