Bentley Continental GT3 revealed at Goodwood Although it shares many elements with the road car, the Continental GT3 is a bespoke model designed solely for motorsport and, at less than 1300kg, it weighs about 1000kg less. Power comes from a twin-turbo 4.0-litre V8 petrol engine that develops 600bhp. Power is transmitted to the rear wheels via a carbon fibre propshaft to six-speed sequential gearbox with a limited slip differential, mounted as a transaxle for optimised weight distribution. Gearshifts are via a pneumatic shift system. As well as wider bodywork than the GT, the GT3 gains a carbon-fibre rear wing, carbon-fibre front splitter and extra vents to aid engine cooling. Despite its motorsport specification and stripped-out interior Bentley says the GT3 remains a hand-crafted car, with the steering wheel, door pulls and seat all hand-trimmed and stitched by its staff at Crewe. The Continental GT3 is expected to start full competition in the FIA Blancpain Series in 2014. It made its dynamic debut at the Goodwood Festival of Speed, driven by 2003 Le Mans champion Guy Smith.
