Unveiled at the 1985 Geneva Salon, Bentley's Turbo R was based on the chassis of the Mulsanne and powered by a modified version of the engine from the Mulsanne Turbo. The chassis changes were especially key to the model's success, as this was to be an unashamedly sporting motorcar, requiring tauter suspension than the Mulsanne. The front anti-roll bar rate was therefore increased by a whopping 60 per cent and that on the rear by no less than 80 per cent. Tuned dampers replaced the standard units of the Mulsanne and a Panhard rod was fitted to limit lateral movement of the axle. A front air dam was added for improved aerodynamics.

The 6,750cc engine with Garrett AiResearch turbo was retuned with Bosch MK-Motronic fuel injection for increased torque. The result was a stump-pulling 487 lb ft - sufficient to launch the leviathan to 60mph in under six seconds and on to a top speed of around 150mph. Braking was by discs all round, ventilated at the front. In order to optimise traction and road holding, the Turbo R was equipped with wider tyres than the Mulsanne, which were mounted on alloy wheels - a first for the marque. The R became one of the Rolls-Royce Group's best-selling models between 1985 and 1995.

The immaculate example on offer is a May 1990 model finished in Cobalt Blue and trimmed in Blue-piped Cream-coloured hide. Though on its fifth keeper it has covered a mere 18,162 miles from new, so is barely run in. This handsome and exceedingly fast motorcar is now on offer complete with: its original wallet of handbooks and stamped service book; collection of invoices; and print-out of the car's MOT history, as well as an advisory-free certificate valid into October next year. An awful lot of Bentley for the money.
