The MG Metro 6R4 (ie: 6-cyclinder, Rear engine, 4-wheel-drive) made its first public appearance at the end of February 1984 in a hastily prepared press launch at the Excelsior Hotel, London Airport. The reason for this was that press speculation was mounting – and in order to undergo a full development programme, Austin Rover could do without the added hassle of playing hide and seek with scoop photographers.

Engine Capacity: 2991cc, Bore: 92mm, Stroke: 75mm
Valve Gear: DOHC, 4 valves per cylinder, toothed belt camshaft drive
Compression ratio: 12:1, Lucas mapped electronic fuel injection
