Aston Martin DB7 Coupe & Volante

It was Victor Gauntlett who first suggested that a new, smaller Aston Martin should be built alongside the big V8 Astons, a car that would, in terms, be a volume seller.

The advent of the Ford Motor Company and the appointment of the late Walter Hayes as Chief Executive of Aston Martin not only provided new funding, but a renewed vigour in the person of Rod Mansfield who, as Engineering Director in 1990, was charged with the development of the 'smaller' Aston Martin, code names DP1999.

The new design, code named NPX, was subjected to far more development and testing than the majority of models to date, with the use of some 30 prototypes which were exposed to extreme conditions and temperatures across the World.

The engine proved to be a light alloy, twin camshaft, supercharged straight six of 3,228cc based on a design that had originated at Jaguar. The cylinder head used 4 valves per cylinder with Zytec electronic multi-point Fuel Injection while the air needed to combust the fuel was delivered by a water cooled Eaton, 'roots' 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 soft-top version. In 1996, the Volante made its debut at the Los Angeles and Detroit motor show.

In 1999, the DB7 received significant engineering enhancements with the introduction of the DB7 Vantage - the first Aston Martin to use a V12 engine.

Aston Martin DB7 Vantage Coupe & Volante

Launched on the 1999 London Motorshow, the DB7 Vantage replaced the six cylinder DB7. The DB7 Vantage, available in both Coupe and Volante body styles, was the first ever Aston Martin to be powered by a 12 cylinder engine.

Incorporating the latest in Formula I technology, it has been designed and developed in close cooperation with the Ford Research and Vehicle Technology Group and Cosworth Technology as part of a long-term and continuing programme to research and develop new designs, materials and manufacturing techniques for implementation by Aston Martin. Features include an engine oil/water heat exchanger to improve cooling efficiency and an ionised gas misfire detection system.

INTRODUCTION

If it hadn’t been for the DB7, Aston Martin would almost certainly be nothing more than a footnote in the motoring hall of fame by now. With just a handful of cars trickling out of the Newport Pagnell gates by the early 1990s, Aston Martin was a basket ca...

Aston Martin DB AR1

With the introduction of the DB7 in 1993, Aston Martin moved out of the speciality niche in the direction of mass-production. In 1999 the six cylinder base model was phased out and replaced by the V12 engined DB7 Vantage. Finally a more powerful GT version was introduced in 2002. At the end of production in 2003, one third of all Aston Martins constructed was a DB7. It wasn't until the final DB7s ...

Aston Martin DB7 Vantage Zagato

While coachbuilders such as Touring, Ghia, Bertone, Allemano and Pininfarina have all made Aston Martins, none has the resonance, or is as closely linked as Aston Martin as Zagato. Put the two together, and any aficionado knows you have something special-a machine that is sportier, more exclusive and faster than its production counterparts. Adding to the allure of the Aston Zagatos is each has bee...
