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.
When rallying really took off in the ’80s and ’90s it spawned a new type of performance car. These cars were built for tarmac and mud stages, so their road-going cousins were naturally well-suited to real world conditions. What’s more, they often had four doors, plenty of legroom and a boot (trunk) in the back. And the best bit? Pretty much anyone could buy one and, depending on how deep your pockets were, become Blomqvist, McRae, or Mäkinen.
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.
The gear changes must be made with a mechanical system, so the paddle shifters were not allowed. However the system was re-allowed in 2015. There was no center differential (earlier it used to be 3 differentials, with a center/3rd differential included), but the new regulation allows only front and rear axle differential (eliminating the center differential to reduce cost), and they must be mechanical, without electronic control or hydraulic or viscous systems (from 2006 to 2010 the center differential and previously all three could be active). Minimum weight is 1200 kg empty and 1350 kg with driver and co-driver (in both cases with only one spare wheel).
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.
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.
With victory in the Safari Rally in 2002, McRae made the record books as the driver with most event wins in the World Rally Championship. His record has since been broken by Carlos Sainz, Sébastien Loeb and Marcus Grönholm. McRae's contract with Ford came to an end following the 2002 season, and after reportedly asking for wages of five million pounds a year, Ford decided against renewing the contract, reluctant to commit such a high amount of their budget to a driver's salary. The two parties split on amicable terms, with Ford's European director of motorsport Martin Whitaker stating "On behalf of all of us at Ford Motor Company I would like to publicly thank Colin and Nicky for their efforts during the past four years with the Ford team. I wish them both well in the future." McRae said of his time with Ford "It's been a very successful four years, we've achieved a lot of very good results and I'm quite happy that myself and Ford have had a very successful partnership."
Rising investor confidence also indicates a rally, and it is perhaps more powerful than any economic indicator because when investors believe something is going to happen (a rally, for example), they tend to take action (purchasing shares in order to profit from expected price increases) that actually turn expectations into reality. Although it is an objective concept, investor sentiment shows through in mathematical measurements such as the put/call ratio, the advance/decline line, IPO activity, and the amount of outstanding margin debt.
