The quest for longer and tougher events saw the re-establishment of the intercontinental rallies beginning with the London–Sydney Marathon held in 1968. The rally trekked across Europe, the Middle-East and the sub-continent before boarding a ship in Bombay to arrive in Fremantle eight days later before the final push across Australia to Sydney. The huge success of this event saw the creation of the World Cup Rallies, linked to Association Football's FIFA World Cup. The first was the 1970 London to Mexico World Cup Rally which saw competitors travel from London eastwards across to Bulgaria before turning westwards on a more southerly route before boarding a ship in Lisbon. Disembarking in Rio de Janeiro the route travelled southward into Argentina before turning northwards along the western coast of South America before arriving in Mexico City.
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.
McRae died on 15 September 2007 when his helicopter, a Eurocopter AS350, crashed 1 mile (1.6 km) north of Lanark, Scotland, close to the McRae family home. McRae's five-year-old son Johnny, and two family friends, Graeme Duncan and Johnny's six-year-old friend Ben Porcelli, also died in the crash. McRae's previously active website, ColinMcRae.com, was later replaced with a memorial screen stating a few details about the crash, and then with a short statement released on behalf of McRae's father, Jimmy, and later a book of condolences.
Rallies usually present a multitude of moneymaking opportunities for investors because prices are generally rising across the board. But rallies don’t last forever, and they don’t always give advance notice of their arrival, so the investor must know when to buy and when to sell to maximize his or her profits. This means the investor must attempt to "time the market" or gauge when a rally has begun and when it is ending.
Colin McRae began his competitive career in motorsport riding trial bikes at an early age, despite being more interested in four wheeled machines rather than two wheel bikes. At the age of sixteen, through the Coltness Car Club, McRae discovered autotesting, he soon traded his bike for a Mini Cooper and started competing. A year later, he began to negotiate with another club member to use his Hillman Avenger for the Kames Stages, a single-staged rally venue not far from McRae's home. McRae finished the event fourteenth; first in his class although he had run most of the event in a higher position.
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 gear changes must be made with a mechanical system, so the paddle shifters were not allowed. However the system was re-allowed in 2015. There was no center differential (earlier it used to be 3 differentials, with a center/3rd differential included), but the new regulation allows only front and rear axle differential (eliminating the center differential to reduce cost), and they must be mechanical, without electronic control or hydraulic or viscous systems (from 2006 to 2010 the center differential and previously all three could be active). Minimum weight is 1200 kg empty and 1350 kg with driver and co-driver (in both cases with only one spare wheel).
