The car was first shown in concept guise at the 2003 North American International Auto Show in Detroit.
It will be built at Aston Martin's Headquarters at Gaydon, Warwickshire, UK, and completes the current Aston Martin line-up. This now comprises the flagship Vanquish S, the elegant DB9 and the agile V8 Vantage.
The long bonnet and two-seater cabin creates an instantly recognisable stance, while minimal front and rear overhangs, combined with a wide track, appear to push the rear wheels out and enhance the extremities of the bodywork.
At the rear a hatchback offers practicality not normally found in sports cars of this type.
The V8 Vantage is the second model to use Aston Martin's unique VH (Vertical Horizontal) architecture.
Constructed from lightweight aluminium extrusions, precision castings and pressings, the underframe is bonded with aerospace adhesives and mechanically fixed with self-piercing rivets.
The new engine is a 4.3 litre, low emissions all aluminium alloy V8, unique to Aston Martin.
The layout of the powertrain adopts a transaxle configuration, whereby the front mid-mounted engine is connected to the transmission - at the rear of the car - via a cast aluminium torque tube and carbon fibre prop-shaft. This configuration provides the car with a 49:51 weight distribution.
Maximum power is 280kW at 7 000 r/min.
The V8 Vantage will be initially offered with a 6-speed manual transmission and other alternatives will be announced at a later date.
