Aston Martin reveals spectacular One-77 technical showcase

The One-77 is Aston Martin’s definitive sports car, one that epitomizes everything Aston Martin from technology, the hand-craftsmanship of the hand rolled aluminum panels to the attention to detail.
With the performance and durability phase of the One-77’s intensive development program soon to commence, the recent 79th Geneva Auto Salon provided the perfect stage on which to reveal the remarkable engineering, advanced technology and exotic materials that lie beneath the One-77’s extraordinary exterior.
The One-77’s structural core is a lightweight and immensely rigid carbon fibre monocoque.
Employing the classic formula of double wishbones at each corner, the One-77 features inboard suspension front and rear, with pushrods employed to transfer vertical suspension movements to the horizontally mounted spring/damper units.
A practice taken directly from racing car design, the main advantages of inboard suspension are a reduction in unsprung weight and the ability to package the suspension components more effectively.
The dampers are fully adjustable and feature advanced Dynamic Suspension Spool Valve (DSSV) technology; a world-first for a road car application.
These special valves are state-of-the-art even at the highest levels of motorsport, and use high-precision machined components to enable the shock-absorbing characteristics of the damper to be changed without having to remove them from the car, as is the norm.
Naturally, such a spectacular chassis demands, and gets, an equally exceptional drivetrain. It comes in the form of an immensely potent 7.3-litre, naturally aspirated V12 engine. Thanks to the adoption of dry-sump oil system the engine is mounted 100mm lower than in any previous V12-engined Aston Martin road car, which helps keep the One-77’s centre-of-gravity as low as possible.
Wearing Pirelli P Zero Corsa tires (255/35 ZR20 front, 335/30 ZR20 rear) developed specifically for the One-77, all 700 hp plus is transmitted to the road through the rear wheels via a new six-speed gearbox.
Top speed is confidently predicted to be in excess of 200 mph, with a 0-60 mph time in approximately 3.5 seconds.
Perhaps more importantly, thanks to the purity of a front-engined, rear-drive layout, the responsiveness and immense tractability of a naturally aspirated V12 and the low mass, high-rigidity properties of a carbon fibre chassis, the One-77 promises a driving experience of unrivalled intensity and excitement while representing the world’s most desirable automotive art form.
