Virage 6.3 litre coupe

(1992 - 1995)

Because 330 bhp is simply not enough, in January 1992, AML Customer Service Division (now known as Aston Martin Works) introduced the Virage 6.3 conversion, based on experience gained on the AMR1 Group C race cars. The work carried out on customers own cars was much more than just an enlargement of the engines capacity to 6347cc. The £50,000 conversion (at 1992 prices) also involved extensive changes to the suspension, brakes, wheels, tyres and bodywork to cope with the additional power and torque.

Initially peak power was quoted as 465 bhp but was revised in 1993 with the adoption of a high lift cam and solid tappets to 500 bhp @ 6000rpm and 480 lb of torque @ 5800rpm – that’s a 60% increase from the standard engine. The 14 inch ventilated and cross drilled disc brakes with four cylinder racing callipers, also derived from the AMR1, were at the time claimed to be the largest fitted to any production car in the world.

Many of the hand-crafted aluminium body modifications related to the 6.3 are well evident in the photographs; substantially flared wheel arches, deep front air dam, boot mounted spoiler, extended sills, extended rear valance and side air vents. The side air vents were a feature of the initial Virage design but were not used on production cars at least initially. They reappeared with the 6.3 and later Virages and also on the Volante and Vantage. Stylish split rim five spoke 10.5*18 inch OZ alloy wheels with 285/45 ZR Goodyear Eagle tyres ensure more than adequate grip and traction. A small number of cars were also modified to 6.3 cosmetic specification retaining the 5.3 engine in unmodified form. These are known as 6.3 Cosmetic or Virage wide body.

Driving through a five or six speed manual ZF gearbox, or three speed automatic transmission, the extra power is sufficient to power the Virage 6.3 to 175mph, with 0-60 and 0-100mph acceleration taking just 5.1 and 11.5 seconds respectively.

Among the photographs below is a 6.3 Virage, photographed at Stratton Motor Company during 1998. It features attractive Vantage style front and rear bodywork, modified at the long established Aston Martin Heritage dealership near Norwich. This is a later picture of the same car pictured at the top of this page.
