All-Wheel Drive cars have more traction (naturally) and can therefore attain higher speeds in a shorter space, but require very precise driving to extract the most from them. Rear-Wheel Drive is quite challenging, requiring a lot of throttle control and very smooth inputs. It’s incredibly fun and sideways, and the ability to successfully handle a Rear-Wheel Drive car through slippery rally conditions is quite rewarding. Both are incredibly fun, and will increase your driving ability and car control beyond what’s possible on a track.
As public interest grew, car companies started to introduce special models or variants for rallying, such as the British Motor Corporation's highly successful Mini Cooper, introduced in 1962, and its successor the Mini Cooper S (1963), developed by the Cooper Car Company. Shortly after, Ford of Britain first hired Lotus to create a high-performance version of their Cortina family car, then in 1968 launched the Escort Twin Cam, one of the most successful rally cars of its era. Similarly, Abarth developed high performance versions of Fiats 124 roadster and 131 saloon.
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.
