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.
We take rally cars based off front-wheel-drive subcompacts for granted now, but the Mini Cooper was the first of the breed. The humble Mini was originally designed to be an affordable city car, but others saw different possibilities. Race car engineer John Cooper took a 997cc engine out of one of his Formula Junior racers and fitted disc brakes to the Mini to create the Mini Cooper. In hotter Cooper S form, the Mini won the Monte Carlo Rally in 1964, 1965 and 1967, setting the template for so many rally cars to come.
Anyone who has ever played Sega Rally 2 will instantly be familiar with this car. Mäkinen won his fourth consecutive WRC title in a red Evo VI, and this car was commissioned as a road-going replica to celebrate that fact. The Tommi special was fitted with a faster-responding titanium turbo, lower suspension, a front strut brace, and quicker steering. The car made 280hp and hit 60mph in 4.5 seconds.
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?]
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.
