Williams Grand Prix Engineering
Created for the short lived Group B rally category, the 4WD mid engined MG Metro 6R4 of 1984 (standing for 6-cylinder, Rear engine, 4-wheel-drive) was a world away from the best selling city car to which it bore only a superficial cosmetic resemblance. The competition car effectively only shared the name of the production Metro as it featured a mid-mounted engine with four wheel drive transmission enclosed within a semi-monocoque seam-welded tubular chassis. The development of this vehicle had been entrusted to Williams Grand Prix Engineering.
