The Vantage GT4 is based on the new European specification V8 Vantage, with modifications to prepare the car for racing. The V8 Vantage was originally launched in 2005, having undergone the most extensive test programme of any Aston Martin, in total over 1.5 million kilometres.
In 2008, Aston Martin announced the new technically enhanced Vantage V8. In production form, the V8 Vantage’s 4.7 litre engine produces 313 kW (420 bhp), giving the car a maximum speed of 290 kph (180 mph) and a 0-100 kph time of 4.8 sec (0-60 mph in 4.7 sec).
Aston Martin’s unique aluminium bonded architecture gives class-leading strength and rigidity, with a front midmounted V8 engine creating optimum front to rear weight distribution and a low centre of gravity – the perfect foundation for a successful race car.
The Vantage GT4’s foundation, is the V8 Vantage. Under the bonnet, the engine is modified to enhance throttle response and outright performance. The engine management system is recalibrated for race use. The Vantage GT4 also has a free flow exhaust system and air filters. The standard V8 dry sump lubrication system is retained, helping to prevent oil surge during extreme cornering. The Vantage GT4 can be supplied with either a six speed manual, or a Sportshift transmission with paddle controls.
At 1,330 kg (2,930 lb), the Vantage GT4 is 300 kg (660 lb) lighter than the standard car. This has been achieved through a range of weight reduction measures. The interior trim is removed with the exception of the facia moulding which is re-trimmed in Alcantara. The console and door casings are replaced by new lightweight mouldings. The chassis has been fitted with a high-strength steel rollcage and Recaro competition seats. A suede-trimmed steering wheel with a quick release mechanism is also fitted as standard. The Vantage GT4’s safety features are completed with a Sabelt sixpoint safety harness with a push-button release and Lifeline Zero 360 gas extinguisher system.
