2003 Arden A-Type Lightweight RS

Known for tuning British marques such as Jaguar and Land Rover, Arden have released their racing version of the A-Type Lightweight, and licensed it for the road. As first seen at the International Motor Show in Frankfurt, the Lightweight RS has successfully completed the end phase development for Arden’s A-Type.

Based on the Jaguar XKR, this extraordinary sports car is built by hand, without automation. The Lightweight RS distinguishes itself from other A-Types through its well-proportioned shape. This unique styling is discretely different through harmonic curves characterized by efficient aerodynamic parts. All the body parts Arden uses are high-quality, weight-reducing compound plastics. Despite the additional steel roll cage, the resulting weight is 3505 lbs (1590 kgs), which is a reduction of 320 lbs (145 kgs).

Specific to the Lightweight RS, a newly developed 4.5 litre V8 engine produces 500 horsepower (373 kW). Displacement and power are increased with the use of a special crankshaft in combination with lighter pistons and connecting rods. Mated to the engine is an Arden exhaust system which includes specially manufactured catalytic converters.

This car’s power is challenged by an equally efficient brake system. With six-piston fixed-calipers and inner-vented brake disks, this racing machine can effectively stop without fade.

The three-part wheels, which are produced by OZ Racing in Arden’s exclusive Sportline design, keep contact with the road surface. The Arden performance running gear, with additional stabilizer and axle friction bearings made of Teflon, were developed especially for the A-Type lightweight RS. The set-up is individually balanced for each customer.

The Lightweight’s interior has been remodeled. The cockpit is dominated by a safety cell which provides the body with additional rigidity. The installation instruments have been kept to the minimum, and the driver sits in Recaro race bucket seats. Nevertheless, Arden did not dispense the features that are so typical for finishing. The instrument panel and the door panels are leather-covered as dictated by tradition, and the steering wheel of this racing car, licensed for road traffic, is covered with Alcantara leather.

After the completion of the A-Type, customers are offered a three-year quality warranty based on the exclusive agreement between Jaguar Germany and Arden. Maintenance can then be performed by Jaguar contract dealers.
