The Vantage GTE has been specifically designed to compete in championships running to ACO GTE regulations and was the very first GT car to be designed at the outset in a bio-ethanol fuelled specification. The Vantage GTE competes in the premier GT Championships in the world including the American Le Mans Series, World Endurance Championship, the European Le Mans Series and the Le Mans 24 hour race.
Under the bonnet, the engine is based on the standard 4.3 litre 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 capacity is increased to 4.5 litres and uses a dry sump lubrication system allowing the engine to be positioned low in the chassis for an optimised centre of gravity. As in the road car, the transmission is mid rear mounted, but with a six-speed sequential 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 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 fibre rear wing designed using computational fluid dynamics. The Vantage GTE 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.
