In 1984, British journalists watched a rally car charge toward them on a cinema screen.
Then a real MG Metro 6R4 burst straight through it.
Behind the driver sat a Rover V8 with two cylinders literally cut off — because the real engine still didn’t exist.
Austin Rover had decided to turn one of Britain’s most ordinary hatchbacks into a Group B monster capable of fighting Audi, Peugeot and Lancia.
Williams designed the chassis. A former Cosworth engineer created a purpose-built naturally aspirated V6. And after more than four years of development, the 6R4 made its WRC debut in 1985 and finished third.
That would be its best result.
But the engine’s story was only beginning.
It later became a twin-turbo rallycross champion — and eventually evolved into the engine used in the Jaguar XJ220, briefly the fastest production car in the world.
