DB7 GT

DB7 GT Description

In production: October 2002 – September 2003

Chassis numbers: Within the Vantage series 303564 – 304455

To some Aston Martin customers, sufficient just is not enough. That is probably why the already powerful Vantage was joined in the range at the 2002 British International Motor Show by the most powerful version of the DB7, the GT. The striking Vertigo Blue example (presumed to be a modified Vantage, chassis number unknown) was displayed prominently on the turntable. For just a small premium over the Vantage (up from £94,680 for the Vantage coupe to £104,500), the DB7 GT has just a little extra something. The V12 was developed to deliver 435bhp (+15) and torque of 410 lb/ft (+10). The suspension had been substantially modified and this stiffened the chassis by 20%. 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 boot lid spoiler. These changes were said to reduce lift by almost 50%. The car also featured twin bonnet vents not dissimilar to those seen on the Vanquish for better air-flow management and to help dissipate heat. Also fitted was distinctive wire mesh grille covering both the upper and lower air intakes.

New 5 spoke 18 inch alloy wheels were fitted with 245/35 front, 265/30 rear low profile Bridgestone tyres that provided optimum levels of performance and grip. The GT featured a free flowing exhaust with a by-pass valve to give an exhaust note just like the Vanquish. The revised Quickshift gear lever on the DB7 GT and racing twin-plate clutch enabled the driver to maximise the use of the increased power and torque and offered a faster gear change. Larger Brembo brake discs and upgraded pads improved braking performance.

The final drive was changed from 3.77 in the Vantage to 4.09 in the GT, so although quoted top speed remained at 185 mph, acceleration was much improved, reducing the time to 60 mph from 5.7 seconds, to a shade under 5 seconds.

Colour choice followed the Vantage with the addition of the GT launch colour, Vertigo Blue, the new metallic shade of Nero Black and Toro Red, a colour more often seen on the early Gaydon VH cars.

Production of the GT only lasted for a few months as it was, in effect, the run out model for the DB7. A small number of production Vantages were used in the development of the model, chassis 300009 and 302253 are the only two so far identified in the Register. Total production of the DB7 GT reached 190 cars, every single one is listed in the Register following extensive research. Of those, 87 were RHD; of the LHD cars, 66 were sold in the North American market.
