Ford Sierra Cosworth – Road-legal

To Be Auctioned


Ford Sierra Cosworth – Road-legal Cosworth Rally/Circuit car professionally built and less than 500 miles since.

At its introduction in 1982, the Sierra’s revolutionary new shape proved a touch more divisive than Ford had anticipated and some serious marketing became a priority, so it was the obvious choice to become the platform for Ford’s new competition aspirations in conjunction with Cosworth. It fitted the brief well as it was rear-wheel drive, had good aerodynamics, albeit being prone to lift at high speeds, and was available as a three-door. The new body kit and rear spoiler would sort out the lift issues but, more importantly, Ford still needed to build 5,000 units for homologation, somewhat worrying when the company’s initial approach to the dealer network came back with an estimate that suggested they could sell around 1,500 units! The eventual sales record is, of course, history. Ford went on to sell 5,545 three-door cars including the RS500, of which only 500 were built, and the Cosworth engine also found its way into nearly 30,000 Ford Sierra Saloons (Cosworth three door, Sapphire two-wheel drive and four wheel-drive).

This 1986 Sierra Cosworth was rebuilt in 2016 to a race-prepared standard (although technically road-legal) by marque specialists including Graham Hathaway of GHR. Originally white, the 909 light-weight shell was stripped back to bare metal and re-sprayed in the Ford Motorsport colours, with genuine Ford decal livery. It sits on white O.Z ‘Group A’ alloys wrapped in new road-legal Michelin tyres with AP Racing 330 brakes. The inside has been stripped, with just bucket seats and a welded-in, multi-point roll-cage in along with lightweight side windows.

The ‘Group A’ YB engine, including the T5 Turbo with restrictor and air injectors, was rebuilt by Dave Brooks, Ford Specialists in Kent and has covered less than 500 miles since the rebuild as displayed on the new speedo which was fitted during the build. It’s coupled to a T5 Cosworth gearbox and AP Racing clutch.

The car is supplied with full documentation relating to the rebuild along with some history prior.
