New racers are based on the latest Vantage which debuted last year.
Aston Martin Racing has revealed its new Vantage GT3 and Vantage GT4 customer racing cars to the public at the 86th 24 Hours of Le Mans, with the Vantage GT3 making its racing debut in the Michelin Aston Martin Racing Le Mans Festival.
The new Vantage GT3 and GT4 are derived from the new Aston Martin Vantage GTE. All three modern Vantage race cars are based on the latest-gen Vantage road car and powered by the same 4.0-litre turbocharged V8 engine, optimised by Aston Martin Racing.
Weighing in dry at 1245kg, the Vantage GT3 produces a boost-variable 535bhp of power and 700Nm of torque. Built from a lightweight aluminium chassis, again based on the road car, it features a steel roll-cage, an Xtrac 6-speed sequential gearbox, an Alcon motorsport multi-plate clutch, Ohlins four-way adjustable dampers, Alcon brakes and Bosch Motorsport ABS. Full details of the GT4 have not yet been revealed.
The Vantage GT3 remains in development until homologated on 1 March, 2019 and replaces Aston Martin's V12 Vantage GT3, which most recently won the Blancpain GT Series Endurance Cup and British GT series.
"Driveability and a wide operating window remain key targets for us as we develop the new Vantage GT3 and GT4 racing cars," says Aston Martin Racing Managing Director John Gaw. "The fact that our customers can still purchase the V12 Vantage GT3 and be competitive seven years after it was introduced is a fantastic legacy to build on, and the new cars will take this concept on in leaps and bounds. The current GT3 is very popular with customers, and there is a desire to spread our marketplace to more championships and at a high level, and from the expressions of interest that we have seen so far I believe we are on track to do that."
