While nowadays we are used to rally cars being visually close relatives to hot hatchbacks and saloons, it wasn’t always this way. The Lancia Stratos was the first car purpose built for the World Rally Championship; however, its rakish supercar looks and Ferrari-sourced V6 suggested it was better suited to the car park outside Monte Carlo’s casino than the world’s toughest rally stages.
Not much is known about the BMW M1 rally car other than the fact that it exists, but that alone warrants inclusion. BMW intended its mid-engined supercar for competition, but not Group B competition. That didn't stop this straight-six masterpiece from entering rallies in the early 80s. Set aside some time to watch some videos of the M1 rally car in action, and thank us later.
Between 1997 and 2010, the regulations mandated that World Rally Cars must have been built upon a production car with a minimum production run of 2500 units. A number of modifications could be made including increasing the engine displacement up to 2.0L, forced induction (including an anti-lag system), addition of four wheel drive, fitment of a sequential gearbox, modified suspension layout and attachment points, aerodynamic body modifications, weight reduction to a minimum of 1230 kg and chassis strengthening for greater rigidity. The maximum width was set at 1770 mm while front and rear tracks shouldn't exceed 1550 mm.
Most of the works drivers of the 1950s were amateurs, paid little or nothing, reimbursed their expenses and given bonuses for winning (although there were certainly exceptions, such as the Grand Prix drivers who were brought in for some events). Then in 1960 came arguably the first rallying superstar (and one of the first to be paid to rally full-time), Sweden's Erik Carlsson, driving for Saab.
