Aston One-77: 60 of 77 sold

Aston Martin has sold 60 of its £1.2 million One-77 hypercars, out of the 77 units it will produce.

More than half of the buyers have also ordered one of the firm's Toyota iQ-based Cygnet city cars, usually in matching colours, to go with their One-77, insiders have revealed.

To help sell the remaining units, Aston is taking the car on a tour of Asia, visiting Japan, Singapore, Hong Kong, Taipei and China.

The One-77 will be powered by the world's most powerful normally aspirated production engine, a 7.3-litre V12 producing 740bhp and 553lb ft.

It has already become the fastest production Aston ever, eclipsing the Vanquish by recording more than 220mph in testing; 0-60mph is expected to take around 3.5sec. Power is transferred to the road using a beefed-up paddle shift-only Graziano gearbox from the DBS.

Features include a carbonfibre monocoque chassis that helps to keep the One-77’s weight down to around 1500kg; active aerodynamics also feature. The One-77 rides on 20-inch forged alloy wheels wearing Pirelli P Zero Corsa tyres.

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.
