2010 Aston Martin DBS

(continued from above)

The need for high-performance stability, handling ability and low kerb weight defined the DBS's form and construction. Accordingly, the DBS becomes the first production Aston Martin to make extensive use of ultra-light carbon-fiber body panels. High levels of performance and control are 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, together with new carbon ceramic brakes and an adaptive damper controlled suspension system.

At the heart of the DBS is a 6.0-liter V12 engine. The DBR9 and DBRS9 race cars are powered by an enhanced version of this same V12, tuned to produce in excess of 600 hp. The shared powerplant continues the strong link between Aston Martin's road and race cars, just as the six-cylinder engine used in the DBR1 inspired a generation of engines in the DB4, DB5 and DB6 in the 1950s and 60s.

As with all current Aston Martins, the engine is hand-assembled at Aston Martin's dedicated engine facility in Cologne, Germany. The classic 6.0-liter 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 510 hp at 6500 rpm. The 3.71:1 final-drive ratio ensures that the additional power is usable, enhancing in-gear acceleration in particular.

A lightweight, rigid structure is the design engineer's ultimate goal, and achieving the right balance between strength and mass is crucial. Like the DB9 and its sibling DBR9 and DBRS9 race cars, the DBS uses Aston Martin's class-leading all-alloy VH (Vertical Horizontal) architecture, a lightweight bonded aluminum structure that provides outstanding strength and rigidity. Aston Martin's engineers have also employed advanced materials and processes to further reduce weight and increase the DBS's performance and dynamics.
