Recording-breaking BTCC Sierra Cosworth for sale

A British Touring Car Championship-winning Sierra Cosworth is heading to auction. The 1990 Cosworth RS500 was driven by Robb Gravett, Mike Smith and Stig Blomqvist to victory in the same year. The fast Ford will go under the hammer at Race Retro at Stoneleigh Park in Warwickshire on 23 February. It could fetch as much as £175,000 to £220,000.

This record-breaking Cosworth RS500 dominated the Group A 1990 BTCC season with lead driver Robb Gravett behind the wheel. For the long distance two-driver races Robb was supported by Stig Blomqvist at Donnington and the late and Mike Smith at Brands Hatch. Now it is being publicly offered for sale for the very first time after being in storage for 20 years.

Chassis number MTRS01 competed under the team Trackstar banner, formed by Mike Smith in 1989 together with ex-Prodive team manager Malcolm Swetnam and Robb Gravett, with the sole ambition of winning the BTCC championship.

The Cosworth was fitted with a new shell and used the running gear from the previous year's Dick Johnson car, together with all the ‘trick bits’ including Eggenberger suspension, a Getrag five-speed 'dog-leg' gearbox and a top-spec Mountune RS500 engine, producing... you guest it, 500bhp. The result was a record-breaking season with nine wins, eight pole positions and eight fastest laps.

With its impressive 1990 livery, this awesome machine is eligible to race in the HSCC ‘Supertourers’, the Grand Prix Legends Touring Car Challenge, as well as numerous other prestigious events.
