Because 330 bhp is simply not enough, in January 1992, AML Customer Service Division (now known as Works Service) 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 is much more than just an enlargement of the engines capacity to 6347cc. The £50,000 conversion (1992 price) also involves changes to the suspension, brakes, wheels, tyres and bodywork to cope with the additional power. Initially power was quoted as 465bhp but was revised in 1993 with the adoption of a high lift cam and solid tappets to 500bhp @ 6000rpm and 480lb 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, are still 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 above picture; 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, five spoke 10.5*18 inch OZ alloy wheels with 285/45 ZR Goodyear Eagle tyres ensure more than adequate grip and traction.

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 5.5 and 11.5 seconds respectively.
