Ford RS Cosworth Collection

Cosworth solidified its association with Ford on road cars by developing the YB series of engines. Starting with the Ford Sierra RS

Cosworth in 1986 with the famous in-line four producing 204 PS, this hugely successful engine destined for great things both on

and off the track. This collection includes three of those famous cars, all very successful for both Ford and Cosworth which made

Ford Cosworth a household name.

By 1980, ‘Ford Cosworth’ had become a household name. Their 3-litre V8 DFV engine had dominated F1, while the four-cylinder BDA had powered RS Escorts to global

rallying glory. They remained, however, two separate companies and Cosworth worked their powerful magic on engine projects for rival manufacturers. In 1983 Stuart

Turner returned to manage Ford’s competition Department and, aware the competition had overtaken Ford in motorsport, visited Cosworth with colleagues to discuss the

future. Cosworth’s design genius, Keith Duckworth, ‘accidently’ left a prototype twin-cam 16V version of Ford’s SOHC T88 2-litre engine in a place where Ford executives

couldn’t help but see it.

The T88 16V twin-cam project had originally been developed as an aftermarket product of which Cosworth hoped to sell around 200 examples a year to enthusiasts

to use in motorsport. Turner and his colleagues pounced on the idea though, and over a pub lunch formulated plans to add a turbocharger and take the 3-door Sierra

Group A saloon car racing. The resultant Cosworth YB engine debuted in the 1985 Sierra Cosworth and transformed the small specialist Northamptonshire-based firm

into major engine manufacturers. The company invested in a new bespoke factory in Wellingborough and by 1986 were producing over 5,000 engines a year

The Sierra Cosworth was successful on track and in the show room; the initial 5,000 examples being sold out after an avalanche of effusive road tests by journalists

smitten by its outrageous performance and styling. Ford then civilised it by building the Sapphire 4-door saloon, a leather-lined ‘executive express’, that gained four-wheeldrive in 1990 and became the most capable saloon car in the world. Stuart Turner then suggested the platform and running gear of the 4x4 be fitted under the smaller

Mk5 Escort bodyshell and created the last chapter of the YB legend, the Escort Cosworth, which took Ford back to rallying glory
