Aston Martin Vantage GT3 and GT4
Aston Martin has unveiled their new customer racing Vantage GT3 and GT4. The competition machines will make their first public appearance at the top endurance race in the world; the 24 Hours of Le Mans.
The Aston Martin Vantage GT3 will make its racing debut this weekend in the Michelin Aston Martin Racing Le Mans Festival. Both costumer racing machines are the polar opposite of the British performance car maker’s road cars. Where those are luxurious GT cruisers, the GT3 and GT4 are stripped no-nonsense motorsport machines. Having said that, they are still gorgeous to behold.
Here are all the details we know at this time.
Aston Martin Vantage GT3
The Aston Martin Vantage GT3 gets a version of the same twin-turbocharged 4.0-liter V8 as the Vantage GTE. The power-plant produces a boost variable 535 horsepower and 516 ft-lb of torque. The race car uses a lightweight aluminum chassis based on the road going version of the Vantage. All of this helps the GT3 weigh just 2,739 lbs. That figure even includes the steel roll cage.
To help get all the power to the back wheels the Vantage GT3 uses an Xtrac six-speed sequential gearbox. It gets a competition ready Alcon motorsport multi-plate clutch. To aid handling the GT3 uses Öhlins four-way adjustable dampers. The Alcon brakes and Bosch Motorsport ABS help it stop on a dime.
The Vantage GT3 will remain in development until it is homologated on March 1st, 2019. At that time it will replace the current V12 Vantage GT3; the most successful customer race car for the racing arm of the British luxury sports car maker.
Aston Martin Vantage GT4
The Aston Martin Vantage GT4 will also get a version of the twin-turbocharged V8 used by the GTE. At this time, most details are still unavailable for the GT4. While Aston Martin Racing fans and customer teams will be able to see the Vantage GT4 this weekend, it will remain in development through 2018 and will be homologated for competition from March 1st, 2019.
“Driveability and a wide operating window remain key targets for us as we develop the new Vantage GT3 and GT4 racing cars,” says Aston Martin Racing Managing Director John Gaw. “The fact that our customers can still purchase the V12 Vantage GT3 and be competitive seven years after it was introduced is a fantastic legacy to build on, and the new cars will take this concept on in leaps and bounds. The current GT3 is very popular with customers, and there is a desire to spread our marketplace to more championships and at a high level, and from the expressions of interest that we have seen so far I believe we are on track to do that.”
Vice President and Chief Special Operations Officer David King said: “The Aston Martin Vantage GT3 is a worthy successor to the V12 Vantage GT3 and represents the core future of our customer racing programme. With the continued growth of GT racing in general and the GT3 category in particular, this new car and its Vantage GT4 brother will lead our expansion in the GT markets around the globe and particular target areas of the US and Asia. We’ve already seen a high level of interest from potential customers and we only expect that to grow as the car evolves closer to its homologation date.”
