The new Aston Martin V12 Vantage GT3 Exposed

Taking over where the DBRS9 left off.

The newest addition to the large Aston Martin racing lineup and younger sibling to the Vantage Zagato is the V12 Vantage GT3. The new racecar looks to build upon the success of the Aston Martin racing program and offer the latest racing technology to customers.

Underneath the ventilated hood of the GT3 racecar sits a modified and upgraded version of the 6.0-liter engine found in the road going Aston Martin V12 Vantage. However, the upgraded engine boasts significantly more power than the production model. The goal Aston Martin set out to achieve was 600 bhp and a hefty 516 lb-ft. of torque. The engine also sits lower in the chassis thanks to a new dry-sump oil system, allowing for proper lubrication at under intense lateral forces and better handling. Power is transferred to each of the rear wheels via carbon fiber propshaft and an Xtrac six-speed sequential semi-automatic transmission with paddle shifters.

Much of the new V12 Vantage GT3 improves upon the successful aspects of the DBRS9. The chassis is made of aluminum and composite bonded together using aerospace techniques for added stiffness. The aerodynamics has also been updated and can generate even greater amounts of downforce if needed. The wheelbase has shrunk, the engine is located at a lower point, and new racing developed ABS and traction control systems now come standard on the new racecar.

The addition of the new V12 Vantage GT3 allows Aston Martin to remain the only automotive manufacturer to have a race car available for every GT classification. The new Aston Martin V12 Vantage GT3 will undergo testing in October that includes a 10,000 km driving program. Each car will be available to customers for £298,000 (+/- 492,000 USD) with deliveries starting at the beginning of 2012.
