It was first seen with Daniel Craig behind the wheel in the James Bond movie Casino Royale.
Aston Martin Chief Executive Officer, Dr Ulrich Bez, said: "The DBS is the ultimate expression of Aston Martin's engineering and technical ability. It offers pure performance without compromise.
"The DBS delivers the complete driving experience and bridges the gap between our road and track cars - the DB9 and DBR9."
The Aston Martin DBS is a 6.0-litre V12 powered, race-bred, two-seater.
It is a super car which is a combination of elegant design, innovative manufacturing processes, race-derived materials and components and Aston Martin's hand-build expertise.
The hand-built V12 produces 380 kW at 6 500 r/min, a top speed of 302 km/h and a 0-100 km/h time of 4.3 seconds.
Aston Martin has made extensive use of lightweight carbonfibre body panels in order to save over 30kg on standard materials. The car weighs 1695kg.
It is also the first road-going Aston Martin to have carbon-ceramic brakes, which are 12.5kg lighter than conventional steel brakes and far more effective at slowing the car down.
The DBS will be built at Aston Martin's global headquarters at Gaydon, near Warwickshire in the UK, joining the current Aston Martin line-up.
This now comprises the DB9, the V8 Vantage Coupe and the Vantage Roadster - launched earlier this year.
Deliveries of the DBS are expected to commence during the first quarter of 2008.
