Aston Martin unveiled the most eagerly anticipated car of the year the new Aston Martin DBS at the Pebble Beach Concours d'Elegance on August 16th 2007, where the company took a starring role as the featured marque.
Aston Martin Chief Executive Officer, Dr Ulrich Bez, said: "The Aston Martin DBS is the ultimate expression of Aston Martin's engineering and technical ability. It offers pure performance without compromise. The Aston Martin DBS delivers the complete driving experience and bridges the gap between our road and track cars - the Aston Martin DB9 and Aston Martin DBR9."
Equally at home on a twisting mountain circuit as on the open road, the DBS is a true thoroughbred. The Aston Martin DBS is a 6.0-litre V12 powered, race-bred, two-seater shaped by the aerodynamic demands of high performance, with an exquisite interior that marries beautifully hand-finished materials with the very latest in performance technology.A combination of elegant design, innovative manufacturing processes, race-derived materials and components and Aston Martin's unrivalled hand-build expertise makes the Aston Martin DBS a luxury sports car without equal. Every line, crease and curve conveys the enormous potential of the Aston Martin DBS, a seductive blend of refinement and raw power, provided by the hand-built V12 producing 380kW (510bhp/517PS), a top speed of 191mph (302km/h) and a 0-62mph (0-100km/h) time of 4.3 seconds.
The Aston Martin DBS will be built at Aston Martin's global headquarters at Gaydon, near Warwickshire in the UK, joining the current Aston Martin line-up. This now comprises the elegant DB9, the agile Aston Martin V8 Vantage Coupe and the critically acclaimed Aston Martin V8 Vantage Roadster.
Aston Martin DBS: Performance
The need for high-performance stability, handling ability and low kerb weight defined the DBS's form and construction. Accordingly, the Aston Martin DBS becomes the first production Aston Martin to make extensive use of ultra-light carbon-fibre body panels. High levels of performance and control are delivered by the combination of inherent light weight, near-perfect weight distribution, a supremely powerful and flexible V12 engine, and a performance-honed six-speed transmission, together with new carbon ceramic brakes and an adaptive damper controlled suspension system.
At the heart of the Aston Martin DBS is a 6.0-litre V12 engine. The DBR9 and DBRS9 race cars are powered by an enhanced version of this same V12, tuned to produce in excess of 600bhp. The shared powerplant continues the strong link between Aston Martin's road and race cars, just as the six-cylinder engine used in the DBR1 also powered the Aston Martin DB4, DB5 and DB6 in the 1950s and 60s.
As with all current Aston Martins, the engine is hand-assembled at Aston Martin's dedicated engine facility in Cologne, Germany. The classic 6.0-litre V12 features a number of power-increasing enhancements. These include a 'by-pass' engine air intake port that opens above 5500rpm to allow more air into the engine, and re-profiled air inlet ports that further improve airflow into the combustion chamber. Combined with a compression ratio of 10.9:1, the result of these enhancements is prodigious power and torque: the Aston Martin DBS delivers 380 kW (510 bhp/517 PS) at 6500 rpm. The 3.71:1 final-drive ratio ensures that the additional power is usable, enhancing in-gear acceleration in particular.
A lightweight, rigid structure is the design engineer's ultimate goal, and achieving the right balance between strength and mass is crucial. Like the DB9 and its sibling DBR9 and DBRS9 race cars, the DBS uses Aston Martin's class-leading all-alloy VH (Vertical Horizontal) architecture, a lightweight bonded aluminium structure that provides outstanding strength and rigidity. Aston Martin's engineers have also employed advanced materials and processes to further reduce weight and increase the Aston Martin DBS's performance and dynamics.
Carbon-fibre panels are used for the boot enclosure, boot lid, door opening surrounds, front wings and bonnet, giving a saving of some 30kg over more conventional materials without any reduction in strength. "There are no restrictions on form or shape in using carbon-fibre," says Marek Reichman, Aston Martin's Design Director, "and the material allowed us to wrap bodywork around the 20" wheels and maintain the precise relationship between the wheel and the bodywork."
Each panel has been carefully sculpted to direct the airflow around the car, into the engine and to help cool the braking system. The carbon-fibre elements are produced using advanced manufacturing techniques developed from the aerospace and motorsport industries.
The new panel-making procedure also delivers an industry-best surface finish, thanks to a patented 'Surface Veil' process. The application of a 200 micron layer of epoxy and glass to the panel delivers a class-A surface that is in line with Aston Martin's tradition of high-quality finishes. Inside the car, the weave patterns on the exposed carbon-fibre elements have been carefully selected to present the most harmonious surfaces.
Aston Martin DBS: Control
As with the DB9 and DBR race cars, the Aston Martin DBS benefits from the inherent characteristics of the VH architecture. The VH underframe consists of pressed, extruded and cast aluminium components, bonded together to create an immensely strong underlying structure.
This structure means that weight is kept to a minimum, with the front-mid mounted engine and rear-mid mounted transaxle ensuring a near perfect weight distribution: 85% of the car's weight is positioned within its wheelbase. The Aston Martin DBS's polar moment of inertia is therefore very low, producing a car with natural agility, a strong, stable platform for the V12's high power output and an exhilarating driving experience.
To take full advantage of its extremely precise and rigid platform, the Aston Martin DBS employs a new and sophisticated Adaptive Damping System (ADS) which uses two separate valves to set the dampers to five different positions, allowing instant adjustment of the car's ride and handling characteristics. The ADS automatically alters the suspension settings to ensure the driver has high levels of control at all times, with the ability to respond instantly to different driving conditions. The dampers can be 'softer', with a corresponding improvement in ride quality, or 'firm', providing improved body control for more spirited driving.
The damper settings are determined by an electronic control unit which takes sensor readings from the car's systems, including throttle position, brake position, steering wheel rotation and vehicle speed. This data establishes the prevailing driving conditions and the demands the driver is making on the car.
The Aston Martin DBS's Adaptive Damping System perfectly captures the car's sporting character, ensuring that stiffer dampers are available for better handling and control when the car is being driven enthusiastically, without compromising ride comfort during 'normal' driving conditions. A designated 'Track' mode automatically sets all dampers to their firmest positions, making it ideal for circuit driving. The Aston Martin DBS is fitted with Pirelli P-Zero tyres that have been developed especially for the car, along with new 20" lightweight alloy wheels.
The DBS also has a revised Dynamic Stability Control (DSC) system, designed to help maintain maximum traction in challenging driving conditions. In default operation, the DSC is automatically on. Select and press the button for two seconds and DSC 'Track' mode is engaged, raising the threshold at which the system intervenes to allow the experienced driver to explore the car's limits. Hold the button for four seconds and DSC is disengaged entirely.
The car's braking system features another innovation, the first time Carbon Ceramic Matrix (CCM) brakes have been used on a road-going Aston Martin. The end result is shorter stopping distances with excellent resistance to fade in even the most demanding driving conditions. CCM brakes are also some 12.5kg lighter than a conventional system, reducing the weight of the car overall and, in particular, the unsprung weight and rotational masses, further enhancing the performance of the suspension.
