In the 1920s, numerous variations on the Alpine theme sprang up in Austria, Italy, France, Switzerland and Germany. The most important of these were Austria's Alpenfahrt, which continued into its 44th edition in 1973, Italy's Coppa delle Alpi, and the Coupe Internationale des Alpes (International Alpine Trial), organised jointly by the automobile clubs of Italy, Germany, Austria, Switzerland and, latterly, France. This last event, run from 1928 to 1936, attracted strong international fields vying for an individual Glacier Cup or a team Alpine Cup, including successful Talbot, Riley, MG and Triumph teams from Britain and increasingly strong and well funded works representation from Adolf Hitler's Germany, keen to prove its engineering and sporting prowess with successful marques like Adler, Wanderer and Trumpf.
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.
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.
In an attempt to cut costs, since 2006 new regulations required mechanical front and rear differentials, while the central differential remained active. Active suspension and water injections were also prohibited. Cars entered by a manufacturer had to be equipped with the same engine for two rallies; further limitations were imposed on the changing of some parts, including suspension, steering, turbochargers and gearboxes.
McRae's death was met by much grief from former colleagues, rivals and fans alike. The announcement of his death took place during qualifying for the 2007 Belgian Grand Prix with ITV commentator James Allen informing viewers of his death. Formula One driver David Coulthard, a good friend of McRae, who was due to represent Scotland along with him in the Race of Champions at Wembley Stadium on 16 December, described him as "an understated yet fantastically talented individual", he also announced that he would race the 2007 Japanese Grand Prix with a helmet livery similar to that of McRae's as a tribute. During the finale of the 2007 Scottish Rally Championship, the "Colin McRae Forest Stages" held in Perth in September 2007, there was no number 1 car as McRae had been due to drive the course car on the event. Instead, his car was parked at the starting point of the rally, where fans were able to sign a book of condolences.
In the Paris–Madrid race of May 1903, the Mors of Fernand Gabriel [fr] took just under five and a quarter hours for the 550 km (340 mi) to Bordeaux, an average of 105 km/h (65.3 mph). Speeds had now far outstripped the safe limits of dusty highways thronged with spectators and open to other traffic, people and animals; there were numerous crashes, many injuries and eight deaths. The French government stopped the race and banned this style of event. From then on, racing in Europe (apart from Italy) would be on closed circuits, initially on long loops of public highway and then, in 1907, on the first purpose-built track, England's Brooklands. Racing was going its own separate way.
In countries where there was no shortage of demanding roads across remote terrain, other events sprang up. In South America, the biggest of these took the form of long distance city to city races, each of around 5,000 to 6,000 miles (8,000–9,500 km), divided into daily legs. The first was the Gran Premio del Norte of 1940, run from Buenos Aires to Lima and back; it was won by Juan Manuel Fangio in a much modified Chevrolet coupé. This event was repeated in 1947, and in 1948 an even more ambitious one was held, the Gran Premio de la América del Sur from Buenos Aires to Caracas, Venezuela—Fangio had an accident in which his co-driver was killed. Then in 1950 came the fast and dangerous Carrera Panamericana, a 1,911-mile (3,075 km) road race in stages across Mexico to celebrate the opening of the asphalt highway between the Guatemala and United States borders, which ran until 1954. All these events fell victim to the cost – financial, social and environmental – of putting them on in an increasingly complex and developed world, although smaller road races continued long after, and a few still do in countries like Bolivia.
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.
