Originally available with a 6 cylinder supercharged engine, the Aston Martin DB7 received significant engineering enhancements in 1999 with the introduction of the Aston Martin DB7 Vantage - the first Aston Martin to use a V12 engine. The introduction of the Aston Martin DB7 Vantage was the direct result of a concentrated 24 months design and development program, which included a complete appraisal of all aspects of the design and the dynamics of the Aston Martin DB7. Customer reaction was phenomenal. In 2001, annual worldwide sales of the DB7 totaled 1339, an increase of nearly 50% from 1999.
