The World Rally Championship now visits nearly all continents, taking its stylish sideways driving style and specialized cars to a vast global market, estimated by some to be second only to the Formula One juggernaut. This has produced unprecedented levels of visibility in recent years, but in many ways removed the motorsport from its grassroots past. For better or worse, rally has become a lucrative business.
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 became very popular in Sweden and Finland in the 1950s, thanks in part to the invention there of the specialsträcka (Swedish) or erikoiskoe (Finnish), or special stage: shorter sections of route, usually on minor or private roads—predominantly gravel in these countries—away from habitation and traffic, which were separately timed. These at long last provided the solution to the conflict inherent in the notion of driving as fast as possible on ordinary roads. The idea spread to other countries, albeit more slowly to the most demanding events.
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.
In Britain, the legal maximum speed of 12 mph (19 km/h) precluded road racing, but in April and May 1900, the Automobile Club of Great Britain (the forerunner of the Royal Automobile Club) organised the Thousand Mile Trial, a 15-day event linking Britain's major cities, in order to promote this novel form of transport. Seventy vehicles took part, the majority of them trade entries. They had to complete thirteen stages of route varying in length from 43 to 123 miles (69 to 198 km) at average speeds of up to the legal limit of 12 mph (19 km/h), and tackle six hillclimb or speed tests. On rest days and at lunch halts, the cars were shown to the public in exhibition halls.[unreliable source?] This was followed in 1901 by a five-day trial based in Glasgow The Scottish Automobile Club organised an annual Glasgow–London non-stop trial from 1902 to 1904, then the Scottish Reliability Trial from 1905. The Motor Cycling Club allowed cars to enter its trials and runs from 1904 (London–Edinburgh, London–Land's End, London–Exeter—all still in being as mud-plugging classic trials). In 1908 the Royal Automobile Club held its 2,000 mi (3,200 km) International Touring Car Trial, and 1914 the important Light Car Trial for manufacturers of cars up to 1400 cc, to test comparative performances and improve the breed. In 1924, the exercise was repeated as the Small Car Trials.
These events were road races in all but name, but in Italy such races were still allowed, and the Mille Miglia continued until a serious accident in 1957 caused it to be banned. Meanwhile, in 1981, the Tour de France was revived by the Automobile-Club de Nice as a different kind of rally, based primarily on a series of races at circuits and hillclimbs around the country. It was successful for a while and continued until 1986. It spawned similar events in a few other countries, but none survive.
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.
