Ginetta's new 370bhp G55

Ginetta will reveal its fastest, most-powerful GT race car yet with the launch of this new G55 at the Autosport International in January.

Pictured here in these official renderings, the G55 will offer GT3-levels of performance and will be a sister car to the successful GT4-spec G50. Both will compete alongside each other in 2011 in the new Ginetta GT Supercup, a support race series to the revitalised BTCC.

Based on the G50, G55’s boasts over that car include a 370bhp 3.7-litre Ford engine, a Hewland gearbox, a cool air induction kit, up-rated front and rear brakes, a new exhaust system and more muscular bodywork offering improved aerodynamic efficiency.

The Ginetta G55 will cost £75,000, while G50 owners can upgrade their cars for £25,000 or take advantage of the British sports car maker’s part-exchange programme.

The 2011 Ginetta GT Supercup, that costs £9750 plus VAT for a G50 and £11,750 plus VAT for a G55, has been set up to offer a class structure that will bring the series in line with most other GT championships across the world.

Ginetta boss Lawrence Tomlinson said the G55 highlighted “a real route into GT3 to all drivers while still providing an affordable way to enjoy top-level racing”.

Its debut at Birmingham’s Autosport International will be on 13 January.
