With the performance and durability phase of the One-77's intensive development programme soon to commence, the 79th Geneva Auto Salon provides the perfect stage on which to reveal the engineering, advanced technology and exotic materials that lie beneath the One-77's extraordinary exterior.

For Aston Martin's Chief Executive, Dr Ulrich Bez, revealing the One-77's secrets is a proud moment: "Right from the very beginning of the project the vision for One-77 was very simple: It had to combine high-technology with hand-built craftsmanship, and demonstrate the unique capabilities and passion of our designers, engineers and technical partners. Quite simply it had to be the ultimate expression of Aston Martin. As you can now see, we have achieved that goal in magnificent style".

Consequently the One-77's structural core is a lightweight and immensely rigid carbon fibre monocoque. Conceived and designed at Aston Martin's Gaydon HQ, the monocoque, or 'tub', has been built in partnership with Multimatic (MTC). As world leaders in carbon composite technology, advanced vehicle analysis and dynamic simulation, MTC brings specialist capabilities to the exacting challenge of the One-77 programme.

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.

The drive train is a 7.3-litre, naturally aspirated V12 engine. Thanks to the adoption of a dry-sump oil system the engine is mounted 100 mm 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. To further aid agility and endow the One-77 with progressive handling and stable, predictable on-limit behaviour, the engine is also mounted 257 mm aft relative to the front wheel centreline.

The One-77's power unit is an extreme evolution of the 6.0-litre V12 engines fitted to the DBS, DB9 and new V12 Vantage models. Like the collaboration with MTC for the build of the chassis, Aston Martin has chosen a partner with which to develop the motor: engine builders, Cosworth.

Wearing Pirelli P Zero Corsa tyres (255/35 ZR20 front, 335/30 ZR20 rear) developed specifically for the One-77, all 700+bhp is transmitted to the road through the rear wheels via a new six-speed gearbox. Controlled via column-mounted paddles behind the steering wheel, this robotised sequential manual is a new generation of Aston Martin's familiar transmission. Though it is made specifically for the One-77 and features specially strengthened internals to cope with the tremendous power and torque, the lessons learned in its development will ultimately find their way into the company's series production models.

With a projected weight of 1,500kg the One-77 will occupy the highest echelons of road car performance. Top speed is confidently predicted to be in excess of 200 mph, with a 0-60 mph time in approximately 3.5sec.
