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.
Unlike the requirements for the preceding Group A cars, manufacturers were no longer required to build "homologation specials" in order to meet approval. The base model did not need to have all the characteristics of the WRC car, as evidenced from cars such the Peugeot 206, 307, Citroën Xsara and Škoda Fabia, which during this period had no road car variant with a turbocharged petrol engine or four wheel drive. One of the requirements was a minimum length of 4000 mm; the standard Peugeot 206 had an overall length of 3835 mm and Peugeot had to produce at least 2500 units featuring extended bumpers to comply with the required dimensions.
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.
The First World War brought a lull to rallying. The Monte Carlo Rally was not resuscitated until 1924, but since then, apart from World War II and its aftermath, it has been an annual event and remains a regular round of the World Rally Championship. In the 1930s, helped by the tough winters, it became the premier European rally, attracting 300 or more participants.
The 959 was one of the most technically advanced road cars of its time, variable torque-split all-wheel drive, tire-pressure monitoring, and a twin-turbo flat-six making over 400 horsepower. Porsche decided to show off the car's capabilities not by taking it racing, but by taking it rallying at the Paris-Dakar. This Rothmans-liveried legend is what resulted.
Rallying is a very popular sport at the "grass roots" of motorsport—that is, motor clubs. Individuals interested in becoming involved in rallying are encouraged to join their local automotive clubs. Club rallies (e.g. road rallies or regularity rallies) are usually run on public roads with an emphasis on navigation and teamwork. These skills are important fundamentals required for anyone who wishes to progress to higher-level events. (See Categories of rallies.) Short special stage practice events on public roads are in some countries organized by the local clubs, with a permission of the local police, the community normally using the road, and the road authority. The public road is closed during these by the organisers or the police.
The funeral for Colin and Johnny took place on 26 September at Daldowie Crematorium near Glasgow, conducted by the Rev Tom Houston, who had married the McRaes, and the Rev Steven Reid, chaplain at Johnny's school. An address was given by Robbie Head, a former rally driver and commentator who was a close friend of McRae's, with the Rev Houston giving the benediction. McRae's niece and nephews performed the tune Highland Cathedral, a popular funeral song. The song "(Sittin' on) the Dock of the Bay" by Otis Redding, a favourite song of McRae's, was played when the family entered the chapel (coincidentally, Redding himself also died in an air crash). The Proclaimers' song "I'm on My Way" was played when they left. Colin and Johnny McRae were cremated in the same coffin. Among the attendees at the funeral were fellow Scottish racing drivers Jackie Stewart and Dario Franchitti.
