RS 500

the Sierra RS500.
Based on 500 examples of the Sierra RS Cosworth the RS 500 had more spoilers and 224hp. The extra airintake above the numberplate and the extra tip on the rear spoiler are the easiest way of distinguishing the RS500 from a standard Sierra Cosworth. Only twenty more hp was produced from the following additions: Garrett T4 turbocharger, much larger intercooler, 8 injectors (only 4 were used on the road car), 9mm bigger intake manifold and thicker engine block walls. Probably Ford's most successful car to date it did win the only World touringcar championship that was ever held, and had 40 victories in a row in the BTCC.

Suspension and Chassis
Genuine RS500 shells were labelled GBBE GG 38600 to GBBE GG 39099 . These chassis labels are found under a small flap next to the drivers seat and also mounted in the engine bay. Both should display the same numbers.

Body Work and Interior
The RS500 had only minor external cosmetic differences to its parent the Sierra 3 door Cosworth:
· The rear tail gate also had a lower spolier in additional to the upper whale tail.
· This Cosworth had discrete RS500 badges on the rear tail gate and front wings.
· Re-designed front bumper and spoiler to aid cooling and air flow.
· The bonnet louvre air vents were also of a slightly different design.
