It's only been a year since Aston Martin launched its Vantage GT4 racing car, but the British maker has already prepared an updated model for the 2011 season. The revised Vantage GT4 is said to be inspired from the firm's V12 Vantage road car, giving it enhanced aerodynamics and increased downforce, while it also features a number of other improvements.

The 2011 GT4 is closely based on the V8 Vantage road car, with which it is shares the same aluminium chassis, base engine and suspension designs.

The aerodynamic changes up front that include a new splitter, help increase downforce and direct cooling air to the brakes and radiator. At the back, Aston Martin added the V12's larger boot 'flip'. The 2011 car also gets a new carbon fibre diffuser and rear underfloor, which according to Aston Martin, create an area of low pressure under the rear of the GT4, thus increasing downforce while also channeling more air through a new rear-mounted high capacity transmission oil cooler.

Along with the aero upgrades and engine tweaks, Aston Martin is also offering as a first the option of a race-developed Bosch ABS and traction control system that has been specifically calibrated by Bosch Motorsport for the Vantage GT4.

The company said that along with its own one-make series, the Aston Martin GT4 Challenge of Great Britain, the new Vantage GT4 will also be eligible for the European GT4 Cup and all other series with a GT4 class.
