Depending on the format, rallies may be organised on private or public roads, open or closed to traffic, or off-road in the form of cross country or rally-raid.
In most cases rallying distinguishes itself from other forms of motorsport by not running directly against other competitors over laps of a circuit, but instead in a point-to-point format in which participants leave at regular intervals from one or more start points.
The stages may vary from flat asphalt and mountain passes to rough forest tracks, from ice and snow to desert sand, each chosen to provide a challenge for the crew and a test of the car's performance and reliability.
[10][11] By the time of the invention of the motor car, it was in use as a noun to define the organised mass gathering of people, not to protest or demonstrate, but to promote or celebrate a social, political or religious cause.
A prize of $10 was awarded to the motorist "approximating the most ideal schedule" between two secret points along the route and who had "the most nearly correct idea of a pleasant and sensible pleasure tour" between the two cities.
[18] Competitors could start at various locations but with a speed limit of 25kph imposed, the competitive elements were partly based on cleanliness, condition and elegance of the cars and required a jury to choose a winner.
[21] From 24 September-3 October 1895, the Automobile Club de France sponsored the longest race to date, a 1,710 km (1,060 mi) event from Bordeaux to Agen and back.
Speeds had now exceeded the safe limits of dusty highways thronged with spectators and open to other traffic, people and animals and there were numerous crashes, many injuries and eight deaths.
This challenging five-day event attracted over 100 entrants to tackle its 1,000 km (620 mi) road section, a hillclimb and a speed trial, but it was marred by poor organisation and confusing regulations.
The Peking-Paris of 1907 was not officially a competition, but a "raid", the French term for an expedition or collective endeavour whose promoters, the newspaper "Le Matin", rather optimistically expected participants to help each other; it was 'won' by Prince Scipione Borghese, Luigi Barzini, and Ettore Guizzardi in an Itala.
Rather gentler (and more akin to modern rallying) was the Glidden Tour, run by the American Automobile Association between 1902 and 1913, which had timed legs between control points and a marking system to determine the winners.
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.
[47] In Italy, Benito Mussolini's government encouraged motorsport of all kinds and facilitated road racing, so the sport quickly restarted after World War I.
[50] The RAC Rally gained International status on its return in 1951, but for 10 years its emphasis on map-reading navigation and short manoeuvrability tests made it unpopular with foreign crews.
Initially, most of the major post-war rallies were fairly gentlemanly, but the organisers of the French Alpine and the Liège (which moved its turning point from Rome into Yugoslavia in 1956) straight away set difficult time schedules: the Automobile Club de Marseille et Provence laid on a long tough route over a succession of rugged passes, stated that cars would have to be driven flat out from start to finish, and gave a coveted Coupe des Alpes ("Alpine Cup") to anyone achieving an unpenalised run;[52] while Belgium's Royal Motor Union made clear no car was expected to finish the Liège unpenalised – when one did (1951 winner Johnny Claes in a Jaguar XK120) they tightened the timing to make sure it never happened again.
The Monte, because of its glamour, got the media coverage and the biggest entries (and in snowy years was also a genuine challenge); while the Acropolis took advantage of Greece's appalling roads to become a truly tough event.
[54] In 1956 came Corsica's Tour de Corse, 24 hours of virtually non-stop flat out driving on some of the narrowest and twistiest mountain roads on the planet – the first major rally to be won by a woman, Belgium's Gilberte Thirion, in a Renault Dauphine.
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.
[58] 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.
[59] 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.
[60] 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.
Disembarking in Rio de Janeiro the route travelled southward into Argentina before turning northwards along the western coast of South America before arriving in Mexico City.
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.
[citation needed] In 1967, a group of American off-roaders created the Mexican 1000 rally, a tough 1,000-mile race for cars and motorcycles which ran the length of the Baja California peninsula, much of it initially over roadless desert.
[76][77] Other examples of features of an itinerary include passage controls, which ensure competitors are following the correct route but have no due time window, the timecard may be stamped or the cars may be observed by officials.
As co-pilots in addition to the aforementioned Pons, the French Michèle Espinos "Biche" stood out, the Swedish Tina Thörner, the Venezuelan Ana Goñi or the Austrian Ilka Minor.
[citation needed] On special stages, the co-driver's role is to notate pace notes during reconnaissance and recite them at the correct point the driver demands when competing.
[citation needed] The co-driver often exercises an important role in strategy, monitoring the state of rivals and in many cases acting as a psychologist, since they also encourage and advise the driver.
Renault bankrolled the small volume sports-car maker Alpine to transform their little A110 Berlinette coupé into a world-beating rally car, and hired a skilled team of drivers to pilot it.
The low production requirement and loose restrictions of Group B led many manufacturers to develop cars much further removed from production models, and so was created a generation of rallying supercars, of which the most radical and successful were the Peugeot 205 T16, Renault 5 Turbo and the Lancia Delta S4, with lightweight fibreglass bodies roughly the shape of the standard car tacked onto spaceframe chassis, four-wheel drive, and power outputs higher than 500 hp (370 kW).
