2003 Aston Martin DB AR1 Concept Pictures, Specifications, Information

Aston Martin showcased a lightweight concept Roadster at the 2003 Los Angeles Motor Show that was designed specifically to appeal to its US customers.

The DB American Roadster 1 (DB AR1) is derived from the DB7 - the most successful Aston Martin of all time. It is based on the DB7 Vantage Volante (convertible) and boasts revised bodystyle with coachwork by Zagato of Italy and incorporates a number of dynamic elements, which have been finely engineered to offer a new dimension to the Aston Martin driving experience.

Available only as a two-seater, the DB AR1 is not a convertible Zagato version of the Coupe - launched in the summer of 2002 - but a possible addition to Aston Martin's exclusive product range.

The DB AR1 has a large distinctive radiator grille and accentuating rear wheel arches, which are also new, while the carefully detailed features such as the reverse/fog light combination provide graphic evidence of intricate hand craftsmanship and quality that has become an Aston Martin trademark.

Aston Martin has yet to conduct performance testing however, it is expected that recent developments of Aston Martin's low emission, all alloy, 6.0-litre V12 engine, means that DB AR1 will benefit from a performance increase, and offer 435bhp - compared with 420bhp of the DB7 Vantage. This increased power together with a revised final drive ratio and active sports exhaust system will not only provide noticeable improvement in mid-range power, but also additional torque - up from 400 lb/ft (DB7 Vantage) to 410 lb/ft, providing a sharper accelerating drive.

An AP twin plate racing clutch, which replaces the single plate clutch found on the DB7 Vantage, combined with the revised quick-shift gear lever - also fitted to the DB7 GT - will enable the driver to maximise use of the increase in power and torque and enjoy a faster gear change.

Aside from a revised body design, the DB AR1 has special multispoke 19" alloy wheels - with revised offset to give a wider track (8x19" front, 9�x19" rear) - equipped with SO2 245/35 ZR19 front and 265/30 rear, low profile Yokohoma tyres.

The active sports exhaust system with rear muffler by-pass valves - as used on the V12 Vanquish - provide the DB AR1 with a very distinctive exhaust note.

A combination of racing-style grooved 355mm (front) and 330mm (rear) Brembo disc brakes and uprated Pagid RS 42-1 front pads provide the DB AR1 with better-sustained performance, with improved resistance to judder and fade, particularly at high speed. An uprated brake booster unit - as used on the V12 Vanquish - assists in providing the driver with progressive braking and a firmer and more consistent pedal feel.
