The Aston Martin One-77 is the first hypercar built by Aston Martin with only 77 examples being produced, and each costing £1,150,000. It was officially revealed at the 2009 Geneva Auto Show with deliveries beginning in 2011. When the car was put into production, Aston Martin claimed that it would replace the McLaren F1 as the world's most powerful car to be powered by a naturally aspirated production engine. The engine itself is a highly modified version of the 5.9L V12 used by the DBS and the V12 Vantage.
