I guess the speed was restricted so that an over-enthusiastic driver doesn’t loose the roof when exploring the the extremes of the performance envelope. The Vantage Volante shares all the exterior features of it’s closed brother. The V12 engine (in stage 1 tune) needed more cooling air than the 6 cylinder and so the trademark Aston grille was enlarged. This meant the creation of new indicators and driving lights which were moved to a new position. These units are reminiscent of features on both the Project cars (DP212, DP214 and DP215) and the DBR1 race car.
DB7 V12 Vantage Volante
(1999 - 2003)
2000MY, 2001MY, 2002MY, 2003MY
When introduced, the DB7 Vantage Volante was one of the fastest open top Aston Martin ever made. Launched simultaneously with the coupe version at the 1999 Geneva Motor Show, the Volante shares the body, chassis and engine modifications of the closed version. Maximum speed with both the 6 speed manual or 5 speed auto transmissions is limited to 165 mph; the sprint from 60 mph takes just 5.1 seconds.
