The Aston Martin DB7 is a grand tourer which was produced by Aston Martin from September 1994 to December 2004. The grand tourer was available either as a coupé or a convertible. The prototype was complete by November 1992, and debuted at the Geneva Motor Show in March, 1993, the car was styled by Ian Callum and Keith Helfet. The six-cylinder DB7 (based on the Jaguar non-supercharged engine AJ6) was positioned as an "entry-level" model below the hand-built V8 Virage introduced a few years earlier. This model was the highest production Aston Martin vehicle ever, with more than 7,000 built before it was replaced by the DB9.

Overview

The DB7, known internally as the NPX project, was made mostly with resources from Jaguar and had the financial backing of the Ford Motor Company, owner of Aston Martin from 1988 to 2007. The DB7's platform is an evolution of the Jaguar XJS's, though with many changes. The styling started life as the still-born Jaguar F type (XJ41 – coupe / XJ42 – convertible) designed by Keith Helfet. Ford cancelled this car and the general design was grafted onto an XJS platform. The styling received modest changes by Ian Callum so that it looked like an Aston Martin. The first generation Jaguar XK-8 also uses an evolution of the XJ-S/DB7 platform and the cars share a family resemblance, though the Aston Martin was significantly more expensive and rare.

The DB7 was engineered in Kidlington, Oxfordshire, by Tom Walkinshaw Racing on behalf of Aston Martin. The engines continued to be built in Kidlington during the production run of the vehicle.

With production of the Virage (soon rechristened "V8" following Vantage styling revisions) continuing at Newport Pagnell, a new factory was acquired at Bloxham, Oxfordshire that had previously been used to produce the Jaguar XJ220, where every DB7 would be built throughout its production run. The DB7 and its relatives were the only Aston Martins produced in Bloxham and the only ones with a steel unit construction inherited from Jaguar (Aston Martin had traditionally used aluminium for the bodies of their cars, and models introduced after the DB7 use aluminium for the chassis as well as for many major body parts).

The convertible Volante version was unveiled at the North American International Auto Show in Detroit in 1996.[1] Both versions have a supercharged straight-six engine that produced 335 bhp (250 kW; 340 PS) and 361 lb·ft (489 N·m) of torque. In the United States, the Coupé sold for $140,000, and the Volante for $150,000. Works Service provided a special Driving Dynamics package, which greatly enhanced performance and handling for drivers who wanted more than what the standard configuration offered.

V12 Vantage

In 1999, the more powerful DB7 V12 Vantage was introduced at the Geneva Motor Show. Its 5.9 litre, 48-valve, V12 engine produced 420 bhp (313 kW; 426 PS) and 400 lb·ft (540 N·m) of torque. It has a compression ratio of 10.3:1. Transmissions were available with either a TREMEC T-56 six speed manual or a ZF 5HP30 five speed automatic gearbox. Aston Martin claimed it had a top speed of either 186 mph (299 km/h) with the manual gearbox or 165 mph (266 km/h) with the automatic gearbox, and would accelerate from 0–60 mph (97 km/h) in 4.9 seconds.[2] It is 4,692 mm long, 1,830 mm (72.0 in) wide, 1,243 mm (48.9 in) high, with a weight of 1,800 kg (3,968.3 lb).

After the launch of the Vantage, sales of the supercharged straight-6 engine DB7 had reduced considerably and so production was ended by mid-1999.

V12 GT and GTA

In 2002, a new variant was launched, named V12 GT or V12 GTA when equipped with an automatic transmission. It was essentially an improved version of the Vantage, its V12 engine producing 435 bhp (324 kW; 441 PS) and 410 lb·ft (560 N·m) of torque for the manual GT, although the automatic GTA retained the 420 bhp (313 kW; 426 PS) and 400 lb·ft (540 N·m) of torque of the standard DB7 Vantage.[3] Additionally, the GT and GTA chassis had substantially updated suspension from the DB7 Vantage models. Aesthetically, compared to the Vantage it has a mesh front grille, vents in the bonnet (hood), a boot (trunk) spoiler, an aluminium gear lever, optional carbon fibre trim and new wheels. It also has 355 mm (14.0 in) front and 330 mm (13.0 in) rear vented disc brakes made by Brembo. When being tested by Jeremy Clarkson on Top Gear in 2003, he demonstrated the car's ability to pull away in fourth gear and continue until it hit the rev limiter: the speedometer indicated 135 mph (217 km/h). Production of the GT and GTA was extremely limited, as only 190 GT's and 112 GTA's were produced worldwide and only 17 were shipped to the US market, for a total of 302 cars.[3]
