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).
The First World War brought a lull to rallying. The Monte Carlo Rally was not resuscitated until 1924, but since then, apart from World War II and its aftermath, it has been an annual event and remains a regular round of the World Rally Championship. In the 1930s, helped by the tough winters, it became the premier European rally, attracting 300 or more participants.

In Africa, 1950 saw the first French-run Méditerranée-le Cap, a 10,000-mile (16,000 km) rally from the Mediterranean to South Africa; it was run on and off until 1961, when the new political situation hastened its demise. In 1953 East Africa saw the demanding Coronation Safari, which went on to become the Safari Rally and a World Championship round, to be followed in due course by the Rallye du Maroc and the Rallye Côte d'Ivoire. Australia's Redex Round Australia Trial also dates from 1953, although this remained isolated from the rest of the rallying world.
Then in 1911 came the first Monte Carlo Rally (later known colloquially as "the Monte"), organised by a group of wealthy locals who formed the "Sport Automobile Vélocipédique Monégasque" and bankrolled by the "Société des Bains de Mer" (the "sea bathing company"), the operators of the famous casino who were keen to attract wealthy sporting motorists. The competitive elements were slight, but getting to Monaco in winter was a challenge in itself. A second event was held in 1912.
McRae's outstanding performance with the Subaru World Rally Team enabled the team to win the World Rally Championship Constructors' title three times in succession in 1995, 1996 and 1997. After a four-year spell with the Ford Motor Co. team, which saw McRae win nine events, he moved to Citroën World Rally Team in 2003 where, despite not winning an event, he helped them win the first of their three consecutive manufacturers' titles. He was appointed a Member of the Order of the British Empire for services to motorsport in 1996.
Although there had been exceptions like the outlandish Ford V8 specials created by the Romanians for the 1936 Monte Carlo Rally, rallies before World War II had tended to be for standard or near-standard production cars, a rule supported by manufacturers because it created a relatively even playing field. After the war, most competing cars were production saloons or sports cars, with only minor modifications to improve performance, handling, braking and suspension. This kept costs down and allowed many more people to afford the sport using ordinary family cars, so entry lists grew into the hundreds.
The causes and characteristics of rallies vary, but most financial theorists agree that economic cycles and investor sentiment both play a role in the creation and momentum of rallies. In general, information about a strong or strengthening economy, indicated by high employment, high disposable income, low inflation and high business profits usually ushers in a rally. The existence of several new trading highs for well-known companies also indicates a rally is occurring. It is important to note that government involvement affects rallies: Changing the federal funds rate or tax rates indirectly encourages economic expansion or contraction.
