Aston Martin One-77 technical showcase

March 3, 2009 by George Skentzos  

After months of teasing and speculation, Aston Martin has finally unveiled its One-77 supercar at the Geneva Motor Show as a technical showcase.

Though not quite in production form just yet with the performance and durability phase of development soon to commence, chassis number one will be on display to showcase the brand’s latest technologies and hand-craftsmanship.

Aston Martin has confirmed that under the bonnet lies a 7.3-litre naturally aspirated V12 engine – an “extreme evolution” of the powerplant from the DBS – which should comfortably churn out more than 522kW.

By using a dry-sump oil system, engineers have been able to mount the engine 100mm lower than any previous V12 Aston Martin which helps keep the One-77’s centre-of-gravity as low as possible.

Similarly, this has also allowed the engine to be positioned 257mm behind the front wheel centreline – maintaining the front-midengined layout shared by all of Aston Martin’s current road car range.

“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.” Chris Porritt from Cosworth explains.

Power is transferred to the rear wheels through a new six-speed robotised sequential manual gearbox which has been developed specifically for the One-77, controlled via column-mounted paddles behind the steering wheel.

The transition of power from engine to tarmac is handled by Pirelli P Zero Corsa tyres (255/35 ZR20 front, 335/30 ZR20 rear) developed specifically for the One-77, while lightweight carbon ceramic brakes help to bring the car to a sudden stop.

Employing double wishbones at each corner, the One-77 features inboard suspension front and rear to reduce unsprung weight and package the components more effectively – a practice taken directly from racing car design.

The dampers are fully adjustable and feature advanced Dynamic Suspension Spool Valve (DSSV) technology which allows the damper settings to be changed without having to remove them from the car.

Under the assumption that this would mean very little to prospective One-77 buyers, Aston Martin engineers will precisely set-up the suspension for each individual owner to best suit their needs – from a comfortable GT, to a machine capable of conquering the Nürburgring Nordschleife.

At its structural core is a lightweight and immensely rigid carbon fibre monocoque, making a significant contribution to the final projected weight of just 1,500kg.

The top speed is anticipated to be well beyond 320km/h with a zero to 100km/h time of around 3.5 seconds.

      Ford is still a shareholder in Aston Martin and long time
      partner Cosworth. Well Done on achieving the amazing One-77

      This is definitely the best looking 4 door coupe.. As it still looks like a coupe and not a squashed sedan [CLS]

      My mistake; I got it mixed up with the equally beautiful Rapide.. You can have your Fezzas; Lambos; Maseratis or whatever.. give me an Aston Martin everty time.. They look and sound heaps better

      Better looking than the Veyron but a full second off the pace. But who cares, give me the Aston.

      Looks fantastic, a shame though this will be a limited edition vehicle. Would be great if they made this the replacement for Vanquish.

      Best thing to leave the motherland for a while. Aston keep on succeeding. If one company should make it out of the GFC alive it should be Aston martin

      They actually manage to make the ‘wings and all’ look work. Honestly the designers at Aston are brilliant.

      The performance does seem a bit low for the price range but the looks more than make up for it. Not to mention the exclusivity.

      actually, 0-100km/h is rather meaningless nowadays as it’s really a matter of good traction control and a fast gearbox. 3.5sec to 100km/h isn’t too bad considering the engine is ahead of the driver. A much indicator of performance nowadays is 0-200km/h. With that sort of power and weight, i would expect under 10s for 0-200km/h.

      “Wheelnut is only has 2 doors” Ha Ha that’s sooo funny…sorry Wheelnut.
      Yep is an awsome vehicle, no doubts about that. Not sure about those vented front wings but I can see the need.

      Agreed Alan – the standing quarter is also a fairer judge of performance.

      Yeah but it looks a million miles an hour better than the Veyron even when standing still

      I’d be too scare to drive one. For fear of being an adult wetting myself in public.
