One-77

One-77 Description

Production from late 2010

Chassis numbers not yet known

In addition to the initial press release, what was also known was that the One-77 (as yet to be formally named) would feature a carbonfibre monocoque with hand formed aluminium body panels and a 7.3 litre 12 cylinder engine. The price was anticipated to be in excess of a million pounds and the absolute maximum production run would be 77. Potential buyers would need to place a deposit of £200,000 to secure this most exclusive Aston Martin of the New-Era.

By the Paris Motor Show in October the company gave a tantalising glimpse of a mock-up ofthe new car, three quarters covered by a grey pin stripe fabric cover, with an occasional glimpse of the front right side. At Geneva 2009, the world got to see the complete mock-up now painted metallic blue and complete with the correct headlights and wheels. Also on press days and the first two public days, AML displayed a rolling chassis complete with full powertrain showing the exceptional detail under the skin of One-77.

As knowledge grew, so did the anticipation and expectation. Then, at long last and unexpectedly, the One-77 world debut occurred in late April 2009, when the car was shown at the Concorso d’Eleganza Ville d’Este on the shores of Lake Como, Italy, winning the Design Award for Concept Cars and Prototypes. The Concorso d’Eleganza car has subsequently been seen at Pebble Beach Concours and events around the world but also appeared at the 2009 AMOC Autumn concours and Spring and Autumn concours in 2010.

By December 2009, AML had announced that the One-77 had undergone high speed testing at a secret proving ground in southern Europe. It had easily broken the 200mph barrier and gone on to a maximum of 220.007mph in the hands of Chris Porritt, the One-77 programme manager. In April 2010, a Morning Frost coloured One-77 made the model’s on-road debut as part of the Tourist Trophy race event where it led a parade of supercars taking the Trophy from London’s Pall Mall to the Silverstone circuit and subsequently completed some very fast laps. The development of the One-77 has been featured on a series of short films posted on-line on the AMLwebsite as well as YouTube.

The One-77constitutes a huge leap forward for the marque; no Aston Martin has ever pushed the envelope quite so much as this car. AML have looked for inspiration to the German DTM racecars which include the most technically advanced front engined, rear drive machines in existence today. The structure of the car is an immensely rigid lightweight carbon fibre monocoque, conceived and designed at Aston Martin’s Gaydon HQ but built in partnership with Multimatic (MTC), a world leader in carbonfibre technology. The seamless body is to be made up of classic hand-crafted rolled aluminium panels from a flat sheet last seen in production at Newport Pagnell. This process allows One-77 to have the minimal amount of individual body panels and joins between them, resulting in smooth, clean lines.

The V12 has been taken to its limit - 7.3 litres with a confirmed output of 750bhp making it the most powerful naturally aspirated road car engine in the world. Whilst based on the standard V12, virtually no components are shared with the 5.9 litre version. The engine, developed in partnership with Cosworth, is much modified with the weight reduced by 25%. The V12 is fitted 26cm behind the front wheel centreline and is the most extreme example of front-mid engined mounting on an Aston Martin. By using dry sump lubrication, the engine sits 100mm lower than in any other V12 Aston. Power is transmitted to the rear wheels by a new generation of Aston Martin’s familiar 6 speed robotised sequential manual gearbox mounted ahead of the rear axle. With an actual track 70mm wider than a DB9, the centre of gravity 80mm lower than a DB9 and 85% of the entire mass of the car being between the axles, the dynamic capability and high speed stability of the car are phenomenal. Brakes are lightweight Carbon Ceramic Matrix behind 20 inch wheels. Employing the racing car formula of double wishbones front and rear, the One-77 features inboard suspension which transfers vertical suspension movements to the horizontally mounted spring/damper units.

The One-77 is the fastest Aston Martin road car ever - tested to 220mph and 0-60 in 3.5 seconds. Most incredible is the projected kerb weight of just 1500kg, which compares to, the stripped out Vantage N24 at 1350kg and the Bugatti Veyron 1888kg.

The Registrar believes that a total of eight prototype and pre-production cars have been built, some of which are detailed below in the register. In late 2010, production is underway with the first car due to be finished in early 2011.
