In the 1920s, numerous variations on the Alpine theme sprang up in Austria, Italy, France, Switzerland and Germany. The most important of these were Austria's Alpenfahrt, which continued into its 44th edition in 1973, Italy's Coppa delle Alpi, and the Coupe Internationale des Alpes (International Alpine Trial), organised jointly by the automobile clubs of Italy, Germany, Austria, Switzerland and, latterly, France. This last event, run from 1928 to 1936, attracted strong international fields vying for an individual Glacier Cup or a team Alpine Cup, including successful Talbot, Riley, MG and Triumph teams from Britain and increasingly strong and well funded works representation from Adolf Hitler's Germany, keen to prove its engineering and sporting prowess with successful marques like Adler, Wanderer and Trumpf.
There are two main forms: stage rallies and road rallies. Since the 1960s, stage rallies have been the professional branch of the sport. They are based on straightforward speed over stretches of road closed to other traffic. These may vary from asphalt mountain passes to rough forest tracks, from ice and snow to desert sand, each chosen to provide an enjoyable challenge for the crew and a test of the car's performance and reliability.
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).
McRae died on 15 September 2007 when his helicopter, a Eurocopter AS350, crashed 1 mile (1.6 km) north of Lanark, Scotland, close to the McRae family home. McRae's five-year-old son Johnny, and two family friends, Graeme Duncan and Johnny's six-year-old friend Ben Porcelli, also died in the crash. McRae's previously active website, ColinMcRae.com, was later replaced with a memorial screen stating a few details about the crash, and then with a short statement released on behalf of McRae's father, Jimmy, and later a book of condolences.
1968 brought the first of a series of British-organised intercontinental rallies, the Daily Express London-Sydney Marathon, which attracted over 100 crews including a number of works teams and top drivers; it was won by the Hillman Hunter of Andrew Cowan/Brian Coyle/Colin Malkin. Not to be outdone, the rival Daily Mirror sponsored in 1970 the London-Mexico World Cup Rally, linking the stadia of two successive football World Cups, on a route that crossed Europe to Bulgaria and back before shipping out from Lisbon to Rio de Janeiro, after looping around South America, and a run through some of the most frightening sections of Peru's road race, the Caminos del Inca, they wrap it up being shipped to Panama and a final run up Central America. The Ford Escort of Hannu Mikkola and Gunnar Palm won. These were followed in 1974 by the London-Sahara-Munich World Cup Rally, and in 1977 by the Singapore Airlines London-Sydney Rally.
