With the MG Metro 6R4, the Austin-Rover Group wanted to compete against Peugeot and Lancia and their Group B rally cars in the mid-1980s. In contrast to the competition, which relied on turbocharged four-cylinder engines, the Metro opted for a free-breathing naturally aspirated six-cylinder engine, but that was not the only difference to the prevailing opinion. Instead of 200 road-going versions to meet homologation volume requirements, slightly simpler versions were built for ambitious racers. This vehicle report describes the origins and technology of the MG Metro 6R4 and looks specifically at the "Clubman" version.
