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.
Longer term rallies are typically the outcome of events with a longer-term impact such as changes in government tax or fiscal policy, business regulation or interest rates. Economic data announcements that signal positive changes in business and economic cycles also have a longer lasting impact that may cause shifts in investment capital from one sector to another. For example, a significant lowering of interest rates may cause investors to shift from fixed income instruments to equities. This would create a rally in the equities markets.
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).
Rallying is also unique in its choice of where and when to race. Rallies take place on all surfaces and in all conditions: asphalt (tarmac), gravel, or snow and ice, sometimes more than one in a single rally, depending on the course and event. Rallies are also run every month of the year, in every climate from bitter cold to monsoonal rain. As a result of the drivers not knowing exactly what lies ahead, the lower traction available on dirt roads, and the driving characteristics of small cars, the drivers are much less visibly smooth than circuit racers, regularly sending the car literally flying over bumps, and sliding the cars out of corners.
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.
