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.
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 remarkable
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."
Chris
Porritt, 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 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 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; 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 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 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 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
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 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.
The
One-77's magnificent 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 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 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.
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 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
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 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 One-77 promises a driving experience of
unrivalled intensity and excitement while representing the world's most
desirable automotive art form
