One 77

2008 - 2012

August 2008 - most of Europe and the US are taking their Summer Holidays, including myself yet AM release one advertisement and a tiny amount of information about a future halo car to be called the One-77. The press release was extremely brief

''One-77 fuses advanced technology with stunning Aston Martin design to create possibly the world’s most desirable automotive art form. Based on a sophisticated carbon fibre chassis with a handcrafted aluminium body, this 7.3 litre V12 super car will deliver exhilarating performance for a strictly limited number of discerning customers.''

Only two other pieces of info were released – the price – £1,000,000 plus taxes – and a limited production run of 77 examples. Potential customers were invited to make a non-refundable £200,000 deposit.

Following a tantalising view of the car three quarters hidden under a cover at Paris, the naked chassis of car number 1 and a mock-up One-77 were shown at Geneva in 2009. The un-bodied chassis didn’t last beyond the press days, but the mock-up took pride of place on the turntable until the show ended.

Then, at long last  and unexpectidly, the One-77 world debut in late April 2009, where the car was shown at the Concorso d’Eleganza on the shores of Lake Como, Italy. winning  the Design Award for Concept Cars and Prototypes.

One-77 Concept

At the Paris Motor Show early in September 2008, the One-77 made a surprise appearance - well sort of. What was shown was a full scale mock-up mostly covered by a 'pin-stripe suit' sewn onto the car to prevent anyone seeing too much. At the same time, AM released a couple more photos but this is still nothing like seeing the car car in the metal which finally broke cover at the Geneva Salon, 2009. Actually this is only a rolling mock-up with no interior, but certainly does show the styling and stance of the real thing.

The measured unveiling of the One-77 stretched over a few months. The low key announcement, the mock up covered with suit fabric, the slowly updated web site and then the full mock up at Geneva. As the knowledge grew, so did the anticipation and expectation. Then, at long last and unexpectidly, the One-77 world debut occured in late April 2009, where the car was shown at the Concorso d’Eleganza on the shores of Lake Como, Italy, winning the Design Award for Concept Cars and Prototypes.

One-77 (Production)

(2011 - 2012)

The One-77 has been a huge leap forward for the marque, no Aston has ever pushed the envelope quite so much as this car has. AML have looked for inspiration to the German DTM racecars in order to see to 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 as we were used to seeing back in the day at Newport Pagnell. The V12 has been taken to it’s limit – 7.3 litres with 750 bhp. Whilst based on the standard V12, virtually no components are shared with the 5.9 litre example. The engine, developed in partnership with Cosworth, is much modified, the weight has been reduced by an almost unbelievable 25%. The V12 is fitted almost 26cm behind the front wheel centreline, the most extreme example of front-mid engined mounting on an Aston ever. All that power is transmitted to the rear wheels by a new generation of Aston Martin’s familiar 6 speed robotised sequential manual. Brakes are lightweight Carbon Ceramic Matrix of course behind 20 inch forged alloy wheels. Employing the classic formula of double wishbones front and rear, the One-77 features inboard suspension front and rear which transfers vertical suspension movements to the horizontally mounted spring/damper units as seen in racecars. The performance of the One-77 has made it the fastest roadgoing AM ever – tested to 220mph and 0-60 in 3.5 seconds. Most incredible is the kerb weight of just 1630kg, for comparison, the stripped out V8 Vantage N24 weighs 1350kg, a new Vanquish, 1739kg

 

Aston Martin One-77

Aston Martin One-77 technical showcase made its debut the Geneva Auto Salon on 3 March 2009. Chassis no.1 was on display as an exposé throughout the show detailing the quintessence of Aston Martin engineering and design expertise.

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 Aston Martin One-77 delivers effortless beauty guaranteed to stir the senses with performance potential eclipsing any previous Aston Martin.

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

For Aston Martin's Chief Executive, Dr Ulrich Bez, revealing the Aston Martin One-77's secrets is a proud moment: "Right from the very beginning of the project the vision for Aston Martin 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."

Chris Porritt, Aston Martin One-77 Programme Manager continued: "We wanted to create something that wows you as much when you see what's under the skin as the exterior styling itself. We started by identifying the most technologically exciting front-engined, rear-wheel drive cars in the world: those from the DTM race series. We then applied the principles and technology that feature heavily in their design and translated it to a road car application."

Consequently the Aston Martin 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 unrivalled specialist capabilities to the exacting challenge of the Aston Martin One-77 programme.

Employing the classic formula of double wishbones at each corner, the Aston Martin 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.

Underlining the truly bespoke nature of the Aston Martin One-77, once delivered to its owner, the car's suspension characteristics will be precisely set-up by Aston Martin engineers to suit their exact requirements, from settings suitable for the ultimate long-distance GT, to a machine capable of conquering the Nürburgring Nordschleife.

While functionality and efficiency are paramount in the design and construction of the Aston Martin One-77, so too is aesthetic beauty. To this end every single component has been crafted from the finest materials with absolute attention to detail. From the mesmerising weave of the glossy carbon fibre tub and the abstract, sculptural beauty of the dry sump's oil reservoir, to the unerring precision of the billet machined aluminium suspension mounts, the Aston Martin One-77's rolling chassis is an automotive masterpiece.

Of course the irony is that the vast majority of these exquisite components will be hidden from view in the finished car, yet each and every piece is a work of art in its own right. It's this extraordinary workmanship and money-no-object commitment to quality that makes the Aston Martin One-77 unique.

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 Aston Martin One-77's centre-of-gravity as low as possible. To further aid agility and endow the Aston Martin 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.

The Aston Martin One-77's magnificent power unit is an extreme evolution of the 6.0-litre V12 engines fitted to the Aston Martin DBSDB9and new V12 Vantage models. Like the collaboration with MTC for the build of the chassis, Aston Martin has chosen a world-leading partner with which to develop the motor: legendary engine builders, Cosworth. It has proved to be the perfect collaboration, as Chris Porritt explains.

"Our brief to the engine team was for them to take the 6.0-litre V12 as far as it could go, both in terms of output and weight reduction. The targets were a power output of no less than 700bhp with a 10 per cent reduction in engine mass. Incredibly, the Aston Martin and Cosworth engineers achieved a mass reduction of some 25 per cent, and although we've yet to complete the final engine calibration work, I'm confident we'll see in excess of 700bhp. It's an awesome accomplishment, but one that's typical of the One-77 project, for it has consistently brought out the very best in everyone involved."

Wearing Pirelli P Zero Corsa tyres (255/35 ZR20 front, 335/30 ZR20 rear) developed specifically for the Aston Martin 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 Aston Martin 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.

It's a mark of the inherent capabilities of Aston Martin's acclaimed lightweight Carbon Ceramic Matrix brake technology that it has been used as the basis for the Aston Martin One-77's braking system. The internals of the callipers have been re-engineered to transmit less heat from the brake pads into the brake fluid, while the discs themselves have been developed to ensure the maximum possible contact area between the face of the disc and the brake pads for improved stopping power. Due to the Aston Martin One-77's increased performance, special attention has also been paid to brake cooling, as the brakes have less time to cool between bursts of acceleration.

With a projected weight of 1,500kg the Aston Martin One-77 will occupy the very highest echelons of road car performance. Top speed is confidently predicted to be in excess of 200mph, with a 0-60mph time in approximately 3.5sec. 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 Aston Martin One-77 promises a driving experience of unrivalled intensity and excitement while representing the world's most desirable automotive art form.

Aston Martin One-77 buying guide (2009-2012)

 

The One-77 is the sort of car around which legends are spun. One customer, so the story went, bought a second example just so he could have it stripped down to its naked carbonfibre tub, with the sole intention of displaying it in his home as a piece of art. Another bought not one, not two, but ten cars. More than one buyer insisted that their One-77s forgo the usual pre-delivery test drive s...
