2005 Aston Martin DBR9

(source Aston Martin) With a very rigid chassis, lightweight materials, optimum weight distribution and a powerful Aston Martin 6.0 litre, normally aspirated V12 engine, the road going DB9 is an excellent starting point for the production of DBR9.

The name DBR9 is derived from the original Le Mans-winning DBR1 car which not only won the 24 Hour race in 1959 but the World Sportscar title too.

Aston Martin Racing will build 12 individually numbered DBR9 Works cars, which will be run by three Works teams in the major international GT series. A limited number of cars will also be built and made available for private individuals to race or keep in collections.

The DBR9 uses the DB9 road car’s aluminium chassis and uses the V12 engine’s cylinder block and heads to develop the race unit. After this the car is re-engineered for competition use.

The gearbox on the DBR9 is a 6-speed sequential unit. The double wishbone suspension is purpose-built and there are large diameter carbon brakes front and rear. The wheels have also been specially designed for the car by OZ Racing and are made from forged magnesium.

In the cockpit, a carbon composite dashboard, lightweight racing seat and the driver’s instrument panels, have replaced all the original car’s trim.

The aerodynamic package of the car has been developed using computational fluid dynamics (CFD). Combined with the desire to follow the same lines as the DB9 road car, this has helped define the overall body shape. All the panels have been specifically hand crafted to fit the DBR9, and, to save weight, are all manufactured in carbon fibre composite (except the roof). The large rear wing is also made from carbon fibre, while to complete the aero package, the under side of the car is flat from the front to the rear diffuser.

The result is a GT racing car with outstanding performance but with the beauty and integrity of an Aston Martin.
