The previous N24 has proven to be one of the most successful cars in its class, winning the Nurburgring 24 Hours this year, as well as several FIA GT4 races. The latest version of the car is an evolution of the N24 with the larger capacity engine being more responsive with increased torque throughout the rev range.
The 4.7L V8 has an engine management system recalibrated for race use. It also has a free flow exhaust system and air filters, and the standard V8 dry sump lubrication system is retained, helping to prevent oil surge during cornering.
At 1,330kg the Vantage GT4 is 300kg 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 molding, which is re-trimmed in Alcantara, and the console and door casings are replaced by new lightweight moldings.
The chassis has been fitted with a high-strength steel roll-cage 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 six-point safety harness with a push-button release and Lifeline Zero 360 gas extinguisher system.
The suspension has also been re-tuned to enhance the handling, including modified front uprights to give increased camber. The 2009 Vantage GT4 also has larger front brake discs with revised cooling. Cast magnesium front and rear wheels are standard fit with high performance Yokohama A048-R tires.
Customers will be able to pick either a manual or sportshift automatic transmission with paddle-shifters, and both gearboxes have a Valeo twin-plate cerametallic racing clutch and lightweight flywheel to complete the powertrain specification.
Pricing will be set at £96,645 (approximately $142,694) when the vehicle goes on sale in January, with Aston Martin targeting both professional and semi-professional race drivers, as well as enthusiasts who wish to use it for track days and club racing.
