In 2011, Aston Martin unveiled the V12 Vantage GT3 as a replacement for the DBRS9 in the GT3 class segment.. The V12 Vantage GT3 has a power output of 600 bhp (447 kW; 608 PS) and 700 N⋅m (516 lb⋅ft) of torque, with a kerb weight of 1, 250 kg (2, 756 lb). The Vantage GT3 has been designed from the ground up to offer customers the latest in race-car technology and embraces all the experience Aston Martin Racing has learnt from years of engineering and competing in international sports car racing with the DBR9, DBRS9 and the latest VANTAGE GTE. Designed to be the current Aston Martin GT3 car for the next five years, the Vantage GT3 is developed so there are no expensive yearly upgrades with the power of the V12 engine being unlocked when required through Balance of Performance. Like all Aston Martin racing cars, the Vantage GT3 uses the Vantage road car’s bonded aluminium chassis to create a light and stiff structure. This combined with a shorter wheelbase and lower engine position contribute to enhanced handling and performance. Driveability is enhanced further with the latest race-developed ABS and traction control systems, which are fitted as standard. As such, the gap between pro and am drivers is substantially reduced. The Vantage GT3 has a modified version of Aston Martin’s production 6.0 litre V12 engine. The dry-sumped engine produces more than 600 bhp with 700 Nm of torque and its position has been optimised further to improve weight balance. Thanks to this built-in level of performance and the performance balancing in this class, the Vantage GT3 does not require expensive yearly upgrades to maintain its competitiveness. A carbon fibre propshaft mates the engine to an Xtrac six-speed sequential transmission with semi-automatic paddle shift gear change.
