1987 Ford Sierra RS 500 Cosworth

The RS500 Cosworth edition was developed for the purpose of making the Ford Sierra unbeatable on race tracks.  In March 1987, Aston Martin Tickford was commissioned to convert 500 Sierra Cosworth’s for this purpose.

The Cosworth RS500 was announced in July 1987, and was homologated in August 1987.

The main difference to the Sierra three-door Cosworth was the uprated Cosworth's competition engine. Its new features were:

  • The Inline-four engine had a thicker walled cylinder block to cope with the rigours of the track

  • Bore X Stroke of 90.8 mm (3.57 in) X 77 mm (3.03 in)

  • Displacement of 1,993 cc (2.0 L; 121.6 cu in)

  • A larger Garrett AiResearch T04 turbocharger

  • A larger air-air intercooler

  • A second set of four Weber IW025 "yellow" fuel injectors and a second fuel rail (not activated in the roadgoing version)

  • An uprated fuel pump

  • A reworked induction system to allow higher power outputs to be realised

  • An uprated oil and cooling system

  • The rear semi-trailing arm beam had extended but unused mounting points

  • Engine output increased to 227 PS (224 hp; 167 kW) at 6000 rpm

  • Max. torque of 277 N⋅m (204 lb⋅ft) at 4500 rpm.

The RS500 also had minor external cosmetic differences to its parent the Sierra three-door Cosworth:

  • The rear tail gate had a lower spoiler in addition to the upper "whale tail", which had an added lip

  • Discreet RS500 badges on the rear tail gate and front wings

  • A redesigned front bumper and spoiler to aid cooling and air flow, including the removal of the fog lamps and their replacement with intake grilles to supplement brake cooling

Exactly 500 RS500s were produced, all of them RHD for sale in the UK only - the biggest market for this kind of Ford car. It was originally intended that all 500 would be black, but in actuality 56 white and 52 moonstone blue cars were produced.
