DBS Performance
The DBS was developed as the ultimate expression of Aston Martin’s engineering and technical ability. The need for high-performance stability, handling ability and low kerb weight defined the car’s form and construction. The DBS is the first production Aston Martin to make extensive use of ultra-light carbon-fibre body panels. Its high level of performance is delivered by the combination of inherent light weight, near-perfect weight distribution, a supremely powerful and flexible V12 engine, and a performance-honed six speed transmission.
The 6.0-litre V12 engine is the heart of the DBS. The DBR9 and DBRS9 race cars are powered by an enhanced version of this same V12, tuned to produce in excess of 600 bhp. The shared powerplant continues the strong link between Aston Martin’s road and race cars, just as the six-cylinder powerplant used in the DBR1 also powered the DB4, DB5 and DB6 in the 1950s and 60s.
Like all current Aston Martin powerplants, the engine is hand-assembled at Aston Martin’s dedicated engine facility in Cologne, Germany. The classic 6.0-litre V12 features a number of power-increasing enhancements. These include a ‘by-pass’ engine air intake port that opens above 5500 rpm to allow more air into the engine, and re-profiled air inlet ports that further improve airflow into the combustion chamber. Combined with a compression ratio of 10.9:1, the result of these enhancements is prodigious power and torque: the DBS delivers 380 kW (510 bhp/517 PS) at 6500 rpm.
The 3.71:1 final-drive ratio ensures that the additional power is usable, enhancing in-gear acceleration in particular.
