Mad Genius

Mad Genius: The Untold Story of Britain's Wild Mid Engined Group B Challenger is an independent, unofficial work of motorsport history that tells the full story of the remarkable British rally car born from the MG Metro 6R4 project. From its origins inside Austin Rover and Williams Grand Prix Engineering to its dramatic RAC Rally debut, its brief Group B career, and its long afterlife in rallycross, hill climbs, and privateer competition, this book follows the machine, the engineers, and the drivers who turned an improbable idea into one of Britain's most unforgettable competition cars.

This is the story of a car that arrived in rallying's wildest age with its own voice, its own engineering logic, and its own personality. It traces the 6R4's development, the brilliance of the V64V engine, the influence of Tony Pond, the impact of Group B's collapse, and the car's lasting legacy in historic motorsport, collector culture, and British performance engineering. Rich in detail and written in a narrative style, this independent book celebrates a machine that defied expectations and became a legend.
