Aston Martin GT2
Aston Martin Racing engineers designed the Vantage GT2 to compete toe-to-toe with Ferrari and Porsche, typically among the strongest competitors in the GT arena.
Under the bonnet, the engine is based on the standard Aston Martin V8 retaining the road car’s cylinder block, heads and crankshaft, but using competition components, including cylinder heads, connecting rods, valves, camshafts and a racing exhaust system. The engine uses a dry sump lubrication system allowing the engine to be positioned low in the chassis for an optimum centre of gravity.
Like in the road car, the transmission is mid rear mounted, but with a six-speed paddle-shift transmission with a ‘flat shift’ and competition clutch. The transmission also has a dedicated oil cooling system and air ventilation.
The bonded aluminium structure is taken directly from the V8 Vantage road car. Into this, Aston Martin Racing integrates an aerospace specification steel roll cage, built to FIA standards.
With the exception of the roof, the bodywork is manufactured from lightweight carbon fibre and features an advanced aerodynamic package with carbon fibre splitter, flat floor and diffuser, and a carbon rear wing designed using computational fluid dynamics. These and other weight reductions ensure the car meets its minimum weight of 1,150 kg (FIA regulations), 1,175 kg (ACO regulations).
The Vantage GT2 retains the road car’s double wishbone suspension layout at the front and rear, but with bespoke wishbones and coil springs over Koni adjustable aluminium bodied dampers. Brembo six-piston racing brakes are fitted front and rear.
