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.
To limit power, all forced induction cars were fitted with a 34 mm diameter air restrictor before the turbocharger inlet, limiting the air flow to about 10 cubic meters per minute. The restriction was intended to limit power output to 300 hp although some WRC engines were believed to produce around 330–340 hp. Engine development did not focus on peak power output but towards producing a very wide powerband (or power curve). Typically, power output in excess of 300 hp was available from 3000 rpm to the 7500 rpm maximum, with a peak of 330–340 hp at around 5500 rpm. At 2000 rpm (the engine idle speed in "stage" mode) power output was slightly above 200 hp.
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.
The term "rally", as a branch of motorsport, probably dates from the first Monte Carlo Rally of January 1911. Until the late 1920s, few if any other events used the term. Rallying itself can be traced back to the 1894 Paris–Rouen Horseless Carriage Competition (Concours des Voitures sans Chevaux), sponsored by a Paris newspaper, Le Petit Journal, which attracted considerable public interest and entries from leading manufacturers. Prizes were awarded to the vehicles by a jury based on the reports of the observers who rode in each car; the official winner was Albert Lemaître driving a 3 hp Peugeot, although the Comte de Dion had finished first but his steam powered vehicle was ineligible for the official competition. This event led directly to a period of city-to-city road races in France and other European countries, which introduced many of the features found in later rallies: individual start times with cars running against the clock rather than head to head; time controls at the entry and exit points of towns along the way; road books and route notes; and driving over long distances on ordinary, mainly gravel, roads, facing hazards such as dust, traffic, pedestrians and farm animals.
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.
