*Iconic sporting Ford
*Highly sought after
*Engine rebuilt in 2004


The sight of rival manufacturers reaping the rewards of successful circuit racing programmes prompted Ford to renew its alliance with engine builder Cosworth to create the eponymous Sierra. Assembly of the minimum 5,000 required for Group A homologation commenced in June 1986 at the company's Genk plant in Belgium. Based on the three-door Sierra bodyshell, the RS Cosworth combined the standard 1,993cc Pinto engine's cylinder block with a forged steel crankshaft and connecting rods, the first time this combination had been seen in a production Ford engine. Topping it off was a Cosworth-developed, twin-camshaft, 16-valve cylinder head fed by a Garrett AiResearch turbocharger, the latter being deemed necessary to achieve a competitive power output for racing, which in time would amount to over 500bhp! Even in standard road trim the Sierra RS Cosworth produced a staggering 204bhp, its Weber-Marelli engine management system ensuring that the resulting stupendous performance was delivered with minimal turbo lag. Needless to say, the standard Sierra underpinnings were comprehensively up-rated to cope.
Delivered new to Bristol Street Motors in Birmingham, this Sierra RS Cosworth has been owned by the vendor since 1996 (bill of sale on file). Notable features include up-rated Koni dampers; centre-lock alloy wheels; Scorpion exhaust system; cold air induction system; dump valve; and a Stage 1 engine chip tune, while the engine was rebuilt (in 2004) using an RS Cosworth 4x4 cylinder block. The engine rebuild invoice is on file and the car also comes with its original service booklet (stamps from 1986 through 1995); sundry invoices; a quantity of old MoTs; and a current V5C document.
