Two years after it made its introduction, Aston Martin Racing has given its Vantage GT4 racecar an update. The firm has reworked the car by enhancing the aerodynamics and increasing the car’s downforce. The 4.7 litre V8 has also been remapped to offer increased levels of power and torque.

The car now features a new front splitter, which increases downforce at the front of the car and improves channelling of cool air to the brakes and radiator. At the rear, the GT4 gains the V12 Vantage’s larger boot ‘flip’. This works together with a new carbon fibre diffuser and rear underfloor, which creates 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. In addition to the engine and aero upgrades, competitors can now choose to include a race-developed Bosch ABS and traction control system from Bosch Motorsport to enhance performance in both wet and dry conditions.

More than 80 Vantage GT4s have been built and sold globally since 2009, and the car has certainly been successful plying its trade in its GT4 competition class – it won the European GT4 Cup this year, as well as the GT4 class at the Dubai 24 Hours, the Nürburgring 24 Hours and the Spa 24 hours.
