2004 Aston MartinEngine
The engine is developed from the V12 used in the Vanquish. The advanced quad-cam 48-valve engine has been designed by Aston Martin engineers in partnership with Ford's RVT (Research and Vehicle Technology), and is unique to Aston Martin.
The crankshaft is new, as are the camshafts, inlet and exhaust manifolds, the lubrication system and engine management. The result is more low-down torque and a more seamless power delivery. Maximum power is 450bhp and maximum torque 420lb ft. Even more impressive, 80 percent of that maximum torque is available at only 1500rpm.
Comparing the Vanquish's engine to that of the DB9, Fitzsimons comments: The Vanquish offers more ultimate performance, the DB9 has more torque over a wider rev range, says Fitzsimons.
In the new DB9, the V12 - which is a significant 11.8kgs (26lb) lighter than the Vanquish V12 - has been fitted as far back and as low as possible, to assist agility and handling. This helps the DB9 achieve its perfect 50:50 weight distribution.
