The car will be known as the Vantage GT2, and is based on the V8-engined road car.
Aston Martin says the new addition means it is now the only manufacturer to offer cars in every GT racing category: GT1 – DBR9; GT2 – Vantage GT2; GT3 – DBRS9; GT4 – Vantage N24.
The company also wants to show off its green credentials with the car, designing it to run on either standard race fuel or E85 bio-ethanol (where regulations allow).
In 2007, Aston Martin Racing successfully converted a standard DBRS9 to run on E85.
Robin Brundle, Aston Martin Racing’s new managing director, said: ‘The new Vantage GT2 completes our product portfolio for 2008 with competitive cars now available in every category.
‘Thanks to our experience with the DBRS9, we have been able to develop a bio-ethanol fuelled version, which will be eligible to compete in an increasing number of series now accommodating this greener fuel, including the American Le Mans Series.’
