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.
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).
Most of the works drivers of the 1950s were amateurs, paid little or nothing, reimbursed their expenses and given bonuses for winning (although there were certainly exceptions, such as the Grand Prix drivers who were brought in for some events). Then in 1960 came arguably the first rallying superstar (and one of the first to be paid to rally full-time), Sweden's Erik Carlsson, driving for Saab.
Driving rules and regulations in the real world sadly prevent us from racing everywhere at breakneck speeds and performing hell-raising stunts and turns. Only professional rally and racing drivers can play out their wildest fantasy’s and satiate their lust for speed on the track or rally course. We watch them with envy as they dangerously accelerate around corners, fly over road bumps and career through all kinds of terrain in their finely tuned rally cars. From the tantalizing dessert races in Dakar, to the high-adrenaline rally championships, there is something inherently cool and exciting about this sport.
Following inspiration from the Colin McRae games, Dirt Rally has come to PC in 2015 as an "early access" title available via the Steam distribution service. Unlike the previous titles, this installment focuses on a realistic simulation of rallying. DiRT Rally has been released in December 2015 and includes some famous Colin McRae cars like his championship winning Subaru and his 2001 Ford Focus.
The Liège continued as uncompromisingly an open road event run to an impossible time schedule, and remained Europe's toughest rally until 1964, by which time it had turned to the wilds of Yugoslavia and Bulgaria to find traffic-free roads; but in the end the pressures were irresistible. The Coupe des Alpes struggled on until 1973 until it too succumbed, its demise no doubt hastened by the decision of the French motor sporting authorities to select the Tour de Corse as its representative event in international rally championships.
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.
The RAC Rally had formally become an International event in 1951, but Britain's laws precluded the closure of public highways for special stages. This meant it had to rely on short manoeuvrability tests, regularity sections and night map-reading navigation to find a winner, which made it unattractive to foreign crews. In 1961, Jack Kemsley was able to persuade the Forestry Commission to open their many hundreds of miles of well surfaced and sinuous gravel roads, and the event was transformed into one of the most demanding and popular in the calendar, by 1983 having over 600 miles (970 km) of stage. It is now called Rally GB.
Analysts spend thousands of hours trying to mathematically determine what will trigger the next rally and how long it will last. Technical analysis is especially prevalent in this effort, although less sophisticated indicators such as hemline fashions or the NFL division of the latest Super Bowl winner also provide fodder for such predictions. This in turn can sometimes lead to speculation that a rally is just around the corner, which can then become a self-fulfilling prophecy.
Between 1997 and 2010, the regulations mandated that World Rally Cars must have been built upon a production car with a minimum production run of 2500 units. A number of modifications could be made including increasing the engine displacement up to 2.0L, forced induction (including an anti-lag system), addition of four wheel drive, fitment of a sequential gearbox, modified suspension layout and attachment points, aerodynamic body modifications, weight reduction to a minimum of 1230 kg and chassis strengthening for greater rigidity. The maximum width was set at 1770 mm while front and rear tracks shouldn't exceed 1550 mm.
