The new design, code named NPX, was styled by Ian Callum and engineered in conjunction with Tom Walkinshaws TWR group. Aston Martin revealed the DB7 at the Geneva Motorshow in 1993, with production starting in 1994 at a new factory in Bloxham, near Banbury in Oxfordshire.
The new TWR built engine was a light alloy, twin overhead camshaft, supercharged straight six of 3,228cc . Featuring 32 valves, Zytec electronic multi-point fuel injection and a water cooled Eaton, 'Rootes' type, supercharger which was driven by a toothed belt from the camshaft.
Although it didn’t appear for almost 3 years after the DB7’s unveiling, Aston Martin had every intention of creating a convertible version. In 1996, the Volante made its debut at the Los Angeles and Detroit motor show and the two models sold alongside each other until being replaced by the DB7 Vantage in 1999.
