Aston Martin One-77
The One-77 is Aston Martin’s definitive sports car, one that epitomises everything Aston Martin from technology, the hand-craftsmanship of the hand rolled aluminium panels to the attention to detail. A culmination of all the marque’s know-how, the One-77 delivers effortless beauty guaranteed to stir the senses with performance potential eclipsing any previous Aston Martin.
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.
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.
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 a 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. To further aid agility and endow the One-77 with progressive handling and stable, predictable on-limit behaviour, the engine is also mounted 257mm aft relative to the front wheel centreline. In so doing the front-mid-engined layout shared by all of Aston Martin’s current road car range has been taken to a new level.
Wearing Pirelli P Zero Corsa tires (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.
