As with the current 4.7 litre Aston Martin Vantage GT4, which made its race debut in 2009, the Aston Martin Vantage GT4 2011 car is closely based on the V8 Vantage road car with key attributes being carried over including the aluminium chassis, base engine and suspension design. In addition to the engine and aero upgrades, competitors can, for the first time, choose a race-developed Bosch ABS and traction control system. This system has been specifically optimised by Bosch Motorsport for the Aston Martin Vantage GT4 to provide race-enhanced performance in both wet and dry conditions.
The Aston Martin Vantage GT4′s new splitter increases downforce at the front of the car, as well as channelling cooling air to the brakes and radiator. At the rear, the car gains the V12′s larger boot ‘flip’. This works together with a new carbon fibre diffuser and rear underfloor, which create an area of low pressure under the rear of the car, to increase downforce. The redesigned underfloor also channels more air through a new rear-mounted high capacity transmission oil cooler.
