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.
Initially, most of the major postwar 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; 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. These two events became the ones for "the men" to do. 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. 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.[unreliable source?]
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.
In the past, most rally courses were not allowed to be scanned prior to the race, and the co-drivers used only maps supplied by the organization. The exact route of the rally often remained secret until race day. Modern rallies have mostly converted to using organizer-supplied notes or allowing full reconnaissance, as opposed to racing the stages blindly. This change has been brought on in large part due to competitor demand.
Built by the freshly created Advanced Vehicle Operations at the Ford Aveley plant in Essex, the Mexico went on sale between 1970 and 1974 with a 1600cc pushrod ohv engine. It cashed in on Ford’s success in the London-Mexico Rally of 1970. With a shade over 90hp, the Mexico could reach a heady 99mph, but this was enough to light up the rubber around the 13” steel wheels mid corner, giving you easily controllable drifts at relatively safe speeds and almost perfect balance.
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).
