Aston Martin DB7 GT
- Production Dates: January 2003 - September 2004
Aston Martin launched the most powerful Aston Martin DB7 model ever made at the 2002 International Birmingham Motor Show.
Based on the DB7 Vantage Coupe, the DB7 GT received a number of dynamic elements which were finely engineered to offer a new dimension to the Aston Martin DB7 driving experience. There were two versions
available; a six-speed manual Coupe (DB7 GT) and a five-speed automatic (GTA).
Exterior Changes:
Recognised as one of the world's most beautiful cars, the DB7 GT received subtle but effective changes to complement the elegant, yet classic body design that since 1993 had epitomised the pedigree, heritage and
tradition of Aston Martin.
Special attention was paid to the aerodynamic balance for high speed stability with the adoption of additional
sweeps for the undertray, wheel arch liner extensions and a revised bootlid emphasised the new look. These additions helped to reduce lift by almost 50%.
Under bonnet air-flow management was assisted by the addition of two distinctive bonnet vents, which also helped dissipate heat. Instantly visible from the exterior were new 5-spoke 18" alloy wheels equipped with
245/40 front, 265/35 rear low profile Bridgestone tyres that provided optimum levels of performance and grip.
Dynamic Changes:
Further development of Aston Martin's low emissions, all alloy, twin-overhead camshaft, 48 valve, 6.0-litre V12 engine generated an increase in power from 420 bhp (DB7 Vantage) to 435 bhp.
This increased power together with a revised final drive ratio and active sports exhaust system – both unique
to the DB7 GT - not only provided noticeable improvement in mid-range power, but also additional torque - up from 400 lb/ft (DB7 Vantage) to 410 lb/ft, giving a faster accelerating, more responsive drive.
The revised quick-shift gear lever on the DB7 GT version and racing twin-plate clutch enabled the driver to maximise use of the increase in power and torque and offers a faster gear change.
