550hp, 4x4, 0-100 kph in less than 2’’5, five cars line-abreast at the start for intense races of 4 to 6 laps on mixed circuits of around 1km, alternating between asphalt and gravel: these are the “explosive” ingredients of Rallycross, a discipline that first saw the light of day in 1967, and whose flagship competition has (since its creation in 1976) always been, and remains so to this day, the FIA European Rallycross Championship.
