New Vanquish S V12: the fastest ever production Aston Martin

Aston Martin has issued the following press release:

The fastest production model ever to be built by Aston Martin is making its world debut at the Paris Motor Show on September 23, 2004.

With a maximum speed in excess of 200mph (321km/h) and a 6.0 litre V12 engine developing 520 horsepower, the Vanquish S has been designed to deliver even greater performance, complemented by subtle suspension and steering changes and a number of interior and external style revisions.

"The Vanquish is our flagship model and the standard 460bhp will continue to be built," said Aston Martin CEO, Dr Ulrich Bez. "However, this derivative makes the car even more exceptional. The latest Vanquish S is not only the fastest Aston Martin ever, but it is the best handling too. It is the ultimate high-performance Aston Martin."

The Vanquish S has received subtle but effective changes to complement its elegant muscular body. The famous Aston Martin grille has a new rounded and more open appearance for better cooling, and an aerodynamic splitter improves high-speed stability.

At the rear, a redesigned boot lid featuring a new high mounted stop lamp reduces lift and improves balance and stability, helping to achieve an impressive Cd figure of 0.32.

These differences on the Vanquish S not only improve the appearance but also enhance performance. All the exterior body panels are constructed from aluminium with each individual panel hand tailored to the central structure to ensure a perfect panel fit. Every carefully detailed feature provides graphic evidence of the painstaking craftsmanship and quality, which is invested in its construction at Aston Martin’s Newport Pagnell site in Buckinghamshire.

Revised steering geometry provides a 20% quicker response, allowing the driver to apply a reduced input for required steering response. This enables the driver to be more precise with inputs - especially on winding roads - and more accurate feedback from the chassis.

The Sports Dynamics suspension, steering and braking package is now standard on the Vanquish S. This includes stiffer springs and dampers and shorter steering arms.

The brakes have been upgraded to incorporate larger six piston calipers and larger grooved and ventilated front discs. The rear discs are 2mm wider for improved heat dissipation. The use of floating discs ensures the driver has consistent pedal feel under heavy braking whilst a new brake pedal assembly reduces travel and enhances pedal feel.

Further development of Aston Martin’s low emissions, all alloy, quad-overhead camshaft, 48 valve, 6.0-litre V12 engine has generated an increase in power from 460bhp to 520bhp (388kW) @ 7000rpm and torque is boosted to 425lb ft (577Nm) @ 5800rpm.

Engine enhancements include new cylinder heads with fully machined inlet ports and combustion chambers to improve airflow, revised engine mapping and new fuel injectors.

The overall interior design is a subtle blend of traditional, classic and modern materials with Bridge of Weir leather upholstery matched to contemporary metal interior fittings and finishes. A number of detailed improvements have been made to the interior of the Vanquish S to enhance the overall appeal.

The luxurious but purposeful two seat or optional 2+2 cabin now features supportive all leather trimmed sports seats with many additional and exquisite detail touches which amply demonstrate the truly special nature of this unique hand crafted sports car.

"The Vanquish S V12 is a combination of state-of-the-art aerospace technology and hand craftsmanship," said Dr Bez. "It is the flagship model of a confident and growing company that is proud to display its heritage but is also determined to make the most technologically modern and inspirational sports cars in the world."

Illustrating Aston Martin’s continuing commitment to customer care Vanquish S customers will be eligible for a complimentary Performance Driving Course. This comprehensive one-to-one driving experience can be taken at one of three proving grounds – Millbrook in the UK, Lommel in Belgium, or Romeo, Michigan, in North America.

With the capacity to continue to turn heads, the design of the Vanquish is already established as a modern classic. Since its launch in 2001, the Vanquish has proved to be a huge success for Aston Martin with over 1500 cars built.

VANQUISH S V12 - Summary
New larger diameter front discs – 378mm in place of 355mm - providing increased swept area and delivering improved cooling with a 33% increase in thermal capacity giving enhanced resistance to fade.
New rear discs – Diameter unchanged at 330mm but 2mm thicker giving a 21% increase in thermal capacity providing enhanced resistance to fade
Floating discs – Maintain consistent pedal feel under heavy braking.
New front caliper – 6 piston in place of 4 piston caliper with 21% larger pad area contributing to improved braking efficiency. Repositioned to the front of the brake disc for optimised location of this larger caliper.
New brake pads – High performance friction material tuned to the disc/caliper to provide enhanced performance and stability under repeated high loads.

Engine Changes
Engine changes include a new cylinder head casting with machined inlet ports and combustion chambers with revised profiles to improve airflow.

A remapped engine management system, together with new fuel injectors and spark plugs takes advantage of the improved air flow and increases power and torque outputs significantly.

New hot forged connecting rods have been designed to handle the increased cylinder pressures.

Performance Difference
Peak power is increased by 60bhp to 520bhp (388kW), which is achieved at 7000rpm. Peak torque increases by 25lb.ft to 425lb.ft (577Nm) which is now delivered at 5800rpm.

Combined with revised final drive gearing (shortened from 3.69:1 to 4.3:1), mid-range performance ‘feel’ is significantly improved; 50-70mph acceleration time (in top gear) is improved by almost two seconds to 6.5 seconds.

Chassis Changes
Vanquish S has the Sports Dynamic suspension, steering and braking package as standard equipment. A recap of the key changes and benefits are:

Revised springs – shortened, reducing ride height by 5mm, and with a change in the spring rate biased to handling.
Revised dampers – increased damping providing improved body control, especially at higher speeds.
Revised steering – shorter ‘steering arms’ providing 20% quicker steering response.
A new front suspension knuckle assembly and new wheel bearing hub assembly which, together with revisions to the steering geometry, provide enhanced steering response, feel and precision.
