The
DBRS9 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 DBRS9 and provides both with a lightweight rigid chassis.
The race engine uses the same aluminium cylinder block and head
as the DB9's 450 bhp 6-litre V12 unit, but with racing modification
it produces around 550 horsepower.
The DBRS9 was styled by Aston Martin Racings 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.
