The Aston Martin DBR9 is a GT1 racecar based on the DB9 grand tourer.
Debuting in 2005 and racing actively in international sportscar racing until the end of GT1 category in 2011. The name DBR9 is derived from the original 24 Hours of Le Mans-winning DBR1 car, named for then-owner David Brown, which not only won the 24 Hour race in 1959 but also the World Sportscar title. The car is most famous for taking two LMGT1 class wins at Le Mans 24 Hours (2007 and 2008) by the Aston Martin Racing factory team.
Based on the Aston Martin DB9 road car, the DBR9 retains the chassis, engine block, and cylinder heads of the road car's V12 engine. The rest of the car is re-engineered for high performance competition use. The DBR9's bodywork is a blend of optimum aerodynamic performance and the styling of the DB9 road car. All the body panels are constructed from carbon fibre composite (except the roof) to minimize the weight of the car. To complete the aerodynamic body, the bottom of the car is flat all the way from the front to the rear diffuser. To optimise rear downforce a carbon fibre wing has been added. The engine develops 625 bhp (466 kW; 634 PS) and 746 N⋅m (550 lb⋅ft). The DBR9 goes from 0 to 60 mph (97 km/h) in 3.4 seconds, and 0 to 100 mph (161 km/h) in 6.4 seconds.
