The hand-built Vantage GT4 was unveiled in Dubai this week after six months of development by Aston Martin Racing, and tested extensively at the Dubai Autodrome.
The 4.7-litre V8 engine has been recalibrated for race use, featuring a free flowing exhaust system and air filters, with the standard V8 dry sump lubrication system maintained to help prevent oil surge during cornering.
An evolution of the previous 4.3 litre Vantage N24, the more responsive larger capacity engine provides increased torque throughout the rev range.
“We have built on this success to develop the Vantage GT4, a competitive racing car for professional and semi-professional drivers, but also a forgiving car which will appeal to enthusiasts who wish to use it for track days and club racing.”
The Vantage GT4 can be supplied with either a six speed manual, or a Sportshift transmission with paddle controls, although both versions feature a Valeo twin-plate cerametallic racing clutch and lightweight flywheel to complete the powertrain specification.
Inside, the car has been fitted with a high-strength steel rollcage and Recaro competition seats, suede-trimmed steering wheel with quick release mechanism, Sabelt sixpoint safety harness with a push-button release and Lifeline Zero 360 gas extinguisher system.
The suspension has only been slightly retuned for competition; this includes larger diameter front and rear anti-roll bars and adjustable ride height aluminium dampers, as well as single rate, flat ground springs with separate helper springs and a modified front subframe to dial in some extra camber.
Active safety systems are directly carried over to the Vantage GT4, including dynamic stability control, traction control, ABS and electronic brakeforce distribution, providing reassurance and enhanced control in slippery conditions.
Aston Martin Racing is now the only manufacturer to produce cars in each of the GT classes: GT1, GT2, GT3 and GT4.
