Background
The 4 wheel drive mid engined MG Metro 6R4 (6-cylinder, rally car, four-wheel-drive) was
developed and built by Williams Grand Prix Engineering on behalf of Rover.
The car was powered by a longitudinally mounted 3 ltr DOHC 24 valve normally aspirated V6 engine, which is rotated 180 degrees so the gearbox is in board of the rear mounted engine.
The four-wheel-drive was permanently engaged, and drove separate propshafts to the front and rear differentials. The rear differential was mounted on the side of the engine sump with one driveshaft running through the sump to the nearside rear wheel.
There is very little remaining of the original bodywork, with the doors and roof being the only metal parts of the bodyshell, as the wings, bonnet and tail gate are constructed of GRP.
The 6R4 originally appeared in two variants, the first of which was the Clubman spec which was the road going version developing in the region of 250 bhp, which cost £40,000, the second was the International spec which developed around 410 bhp.
The 6R4 never reached its full potential on the rally scene, as its only real season of competition was marred by teething trouble with the engine, and as Group B cars were outlawed by the FISA in 1986, its development was cut short. Despite its world rally championship appearances being cut short, the car did go on to substantial success in both the British and European Rallycross Championships.
This Car
Is a genuine ex-works car and is unique in the fact that it is the only works left hand drive car ever built.
The car made its debut in the hands of Malcolm Wilson on the 1986 Tour de Corse, before passing to Harri Toivonen who drove it on the 1986 1000 Lakes and RAC rallies.
Following the 1986 RAC Rally the car was loaded into a container and shipped across the Atlantic where it was exhibited in a museum in an untouched condition.
In 2011 the car was repatriated into the UK and reconditioned by INRacing. Instead of now residing in a museum it is used on a number of demonstration events.
