MG Metro 6R4

The MG Metro 6R4 is a snarling, mid-engined beast born from the feverish dreams of British motorsport engineers during the wild Group B rally era of the 1980s. Developed by Austin Rover in collaboration with Williams Grand Prix Engineering, this compact hatchback was transformed into a rally monster, complete with a bespoke 3.0-liter naturally aspirated V6 engine—an unusual choice in an era dominated by turbocharged rivals.

Unlike its contemporaries, the 6R4 eschewed forced induction, relying instead on raw displacement and a ferocious, high-revving character that delivered instant throttle response and an unforgettable soundtrack. Its aggressive, boxy bodywork—wider arches, towering spoilers, and gaping intakes—wasn't just for show; every vent and wing served a clear aerodynamic or cooling purpose, embodying the brutal functionality that defined Group B rallying.

Though its competitive career was short-lived, the Metro 6R4 left an indelible mark on motorsport history. It clinched podium finishes in the 1985 RAC Rally, showcasing its potential amidst fierce competition. Today, the 6R4 enjoys cult status, revered by enthusiasts for its uncompromising design, visceral driving experience, and its role in one of motorsport's most thrilling—and controversial—chapters.
