ViperBaz UK commented about the DB9R. Based on the following data, what is your point? The DB9R is a very limited production model that bears little INTERNAL and weight resemblance to the street car. I believe that only about twelve were made.
"The DBR9 GT racing car is based on the latest Aston Martin production sports car - the DB9 - but is significantly modified for competition use. The DB9’s bonded-aluminium body architecture is shared with the DBR9 and provides both with a lightweight rigid chassis. The race engine uses the same aluminium cylinder block and head as the DB9’s 450bhp 6-litre V12 unit, but with racing modification it is expected to produce in the region of 600bhp.
The DB9’s double wishbone suspension configuration is retained on the DBR9, but features up-rated components and a revised geometry for racing purposes. Formula One style carbon brakes are fitted front and rear and a competition, six-speed sequential gearbox is mounted at the rear axle.
The DBR9 was styled by Aston Martin Racing’s own design team who made extensive use of Computational Fluid Dynamics to optimise the aerodynamics before producing the final body surface. The panels are HAND MADE from carbon-fibre composite, helping the car to meet its 1,100kg minimum weight and giving it a power to weight ratio of 550bhp per tonne - more than double that of the road car
