In 1980, a German car maker, Audi, at that time not noted for their interest in rallying, introduced a rather large and heavy coupé version of their family saloon, installed a turbocharged 2.1 litre five-cylinder engine, and fitted it with four-wheel drive. Thus the Audi Quattro was born. International regulations had prohibited four-wheel drive; but FISA accepted that this was a genuine production car, and changed the rules. The Quattro quickly became the car to beat on snow, ice or gravel; and in 1983 took Hannu Mikkola to the World Rally Championship title. Other manufacturers had no production four-wheel drive car on which to base their response, so FISA was persuaded to change the rules, and open the Championship to cars in Group B. This allowed cars to be much further removed from production models, and so was created a generation of rallying supercars, of which the most radical and impressive were the Peugeot 205 T16, Renault 5 Turbo and the Lancia Delta S4, with flimsy fibreglass bodies roughly the shape of the standard car tacked onto lightweight spaceframe chassis, four-wheel drive, and power outputs reportedly as high as 600 hp (450 kW). Further Group B cars were developed by Ford (the RS200), British Leyland (the Metro 6R4) and many others, but these were less successful.
Longer term rallies are typically the outcome of events with a longer-term impact such as changes in government tax or fiscal policy, business regulation or interest rates. Economic data announcements that signal positive changes in business and economic cycles also have a longer lasting impact that may cause shifts in investment capital from one sector to another. For example, a significant lowering of interest rates may cause investors to shift from fixed income instruments to equities. This would create a rally in the equities markets.
Pacenotes are a unique and major tool in modern rallying. Television spectators will occasionally notice the voice of a co-driver in mid-race reading the pacenotes over the car's internal intercom. These pacenotes provide a detailed description of the course and allow the driver to predict conditions ahead and prepare for various course conditions such as turns and jumps.
In Germany, the Herkomer Trophy was first held in 1905, and again in 1906. 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 sadly it was marred by poor organisation and confusing regulations. One participant had been Prince Henry of Austria, who was inspired to do better, so he enlisted the aid of the Imperial Automobile Club of Germany to create the first Prinz Heinrich Fahrt (Prince Henry Trial) in 1908. Another trial was held in 1910. These were very successful, attracting top drivers and works cars from major teams – several manufacturers added "Prince Henry" models to their ranges. The first Alpine Trial was held in 1909, in Austria; by 1914, this was the toughest event of its kind, producing a star performance from Britain's James Radley in his Rolls-Royce Alpine Eagle.
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.
Rallying is also unique in its choice of where and when to race. Rallies take place on all surfaces and in all conditions: asphalt (tarmac), gravel, or snow and ice, sometimes more than one in a single rally, depending on the course and event. Rallies are also run every month of the year, in every climate from bitter cold to monsoonal rain. As a result of the drivers not knowing exactly what lies ahead, the lower traction available on dirt roads, and the driving characteristics of small cars, the drivers are much less visibly smooth than circuit racers, regularly sending the car literally flying over bumps, and sliding the cars out of corners.
Two ultra long distance challenges took place at this time. 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. The New York–Paris of the following year, which went via Japan and Siberia, was won by George Schuster and others in a Thomas Flyer. Each event attracted only a handful of adventurous souls, but in both cases the successful drivers exhibited characteristics modern rally drivers would recognise: meticulous preparation, mechanical skill, resourcefulness, perseverance and a certain single-minded ruthlessness. The New York–Seattle race of 1909, if shorter, was no easier. 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.
Road rallies are the original form, held on highways open to normal traffic, where the emphasis is not on outright speed but on accurate timekeeping and navigation and on vehicle reliability, often on difficult roads and over long distances. They are now primarily amateur events. There are several types of road rallies testing accuracy, navigation or problem solving. Some common types are: Regularity rally or a Time-Speed-Distance rally (also TSD rally, testing ability to stay on track and on time), others are Monte-Carlo styles (Monte Carlo, Pan Am, Pan Carlo, Continental) rally (testing navigation and timing), and various Gimmick rally types (testing logic and observation).
The causes of rallies vary. Short-term rallies can result from news stories or events that create a short-term imbalance in supply and demand. Sizeable buying activity in a particular stock or sector by a large fund, or an introduction of a new product by a popular brand, can have a similar effect that results in a short-term rally. For example, almost every time Apple Inc. has launched a new iPhone, its stock has enjoyed a rally over the following months.
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.
McRae rejoined Prodrive for the 2004 24 Hours of Le Mans where he took third place in the GTS class, and ninth position overall in a Ferrari 550-GTS Maranello partnering Darren Turner and Rickard Rydell. Fellow countryman, and Le Mans winner Allan McNish commented that "Colin has adapted far better than people expected" to endurance sportscar racing.
While nowadays we are used to rally cars being visually close relatives to hot hatchbacks and saloons, it wasn’t always this way. The Lancia Stratos was the first car purpose built for the World Rally Championship; however, its rakish supercar looks and Ferrari-sourced V6 suggested it was better suited to the car park outside Monte Carlo’s casino than the world’s toughest rally stages.
