The Aston Martin One-77 is a two-door coupé built by the British car manufacturer Aston Martin. It first appeared at the 2008 Paris Motor Show, although the car remained mostly covered by a "tailored skirt" throughout the show, before being fully revealed at the 2009 Geneva Motor Show, and deliveries from the beginning of 2011. There was a limited run of 77 cars, giving part of the name of the One-77, and sold for £1,150,000 ($1.5 million or €1.33 milion).
The One-77 features a full carbon fibre monocoque chassis, a handcrafted aluminium body, and a naturally aspirated 7.3 litre (7312 cc) V12 engine with 750 hp (560 kW). Aston Martin claimed it would be the most powerful naturally aspirated production engine in the world when the first car was delivered. The top speed was estimated to be 200 mph (320 km/h) but actual tests in December 2009 showed a figure of 220.007 mph (354.067 km/h), with a 0 to 60 mph (0 to 97 km/h) time of approximately 3.5 seconds.
