What do you do when you're Mercedes-Benz in the late 1970s and you want to go rallying, but your sportiest car is a luxury cruiser that isn't very sporty? You take the C107 SLC Coupe rallying anyways. In an era dominated by nimble cars like the Lancia Stratos and Ford Escort, the 450SLC must have been quite a sight, but Mercedes actually had some competition success. Mercedes won the 1978 South American rally and was able to get 4th place in a Manufacturers Championship.
Starting in 2011, rules for WRC cars changed to be more restrictive. Now regulations were derived from Super 2000 cars with a different aerodynamic kit. The cars were smaller models (there was no longer a minimum 4m length), with a 1600 cm3 direct injection turbo-charged engine with a 33 mm diameter air restrictor and a maximum pressure of 2.5 bar absolute (this will limit torque to about 400 N.m or less[6]).
In the wake of the ever more advanced rally cars of the 21st century is a trend towards historic rallying (also known as classic rallying), in which older cars compete under older rules.[64][65] This is a popular sport and even attracts some previous drivers back into the sport. Many who enter, however, have started their competition careers in historic rallying.
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.
