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.
But this wasn’t enough. By 1984 rallying was all but deregulated, and Audi Sport introduced the Sport Quattro: a shortened, more powerful version of the original coupe, and regulations insisted that 214 were built for the road. With its wheelbase shortened a meaningful 12.6 inches between the B- and C-pillars, the Sport Quattro was more nimble and the bodywork featured numerous GRP and carbon-Kevlar panels. A massive KKK-K27 turbocharger helped increase power to 302hp on the road, while Stig Blomqvist had access to over 450hp in the rally Group B version.
For 2003, McRae signed for Citroën, a team of winning pedigree due to its successes of the previous year with young Frenchman Sébastien Loeb but otherwise undertaking its first complete campaign at World Rally Championship level. McRae's second-place finish on his début in Monte Carlo alongside Loeb and Carlos Sainz whom, aboard the Xsara WRC, helped complete a 1–2–3 finish, transpired to be the finest result he would achieve for the team, for the season was to end with seventh in the drivers' championship, with no victories. Rule changes that were to be brought in for the 2004 season changed the previous practice of having three nominated points-scorers within a team to two. With Loeb partway through a multiple year contract, this meant the Citroën factory team, under Guy Frequelin's leadership, were forced to choose between dropping McRae or Sainz. With Sainz being the more successful of the two during the 2003 season, it was McRae who had to look elsewhere for 2004. David Richards, McRae's former boss at Subaru, who had by now taken over WRC's commercial rights holders ISC and worried that the loss of a character like McRae would damage his ability to market the sport, set about trying to help McRae find a drive for 2004. McRae was unable to find a team, and for the first time in over ten years he would not be competing in the World Rally Championship.
To whom Mrs Veneering incoherently communicates, how that Veneering has been offered Pocket-Breaches; how that it is the time for rallying round; how that Veneering has said 'We must work'; how that she is here, as a wife and mother, to entreat Lady Tippins to work; how that the carriage is at Lady Tippins's disposal for purposes of work; how that she, proprietress of said bran new elegant equipage, will return home on foot--on bleeding feet if need be--to work (not specifying how), until she drops by the side of baby's crib.
This particular era was not to last. On the 1986 Rallye de Portugal, four spectators were killed; then in May, on the Tour de Corse, Henri Toivonen went over the edge of a mountain road and was incinerated in the fireball that followed. FISA immediately changed the rules again: rallying after 1987 would be in Group A cars, closer to the production model. One notably successful car during this period was the Lancia Delta Integrale, dominating world rallying during 1987, 1988, 1989, 1990, 1991 and 1992 – winning six consecutive world rally championships, a feat yet unbeaten.
Other rallies provide organizer-created "route notes" also referred to as "stage notes" and disallow reconnaissance and use of other pacenotes. These notes are usually created using a predetermined pacenote format, from which a co-driver can optionally add comments or transpose into other pacenote notations. Many North American rallies do not conduct reconnaissance but provide stage notes through the use of the Jemba Inertia Notes System, due to time and budget constraints.
Following inspiration from the Colin McRae games, Dirt Rally has come to PC in 2015 as an "early access" title available via the Steam distribution service. Unlike the previous titles, this installment focuses on a realistic simulation of rallying. DiRT Rally has been released in December 2015 and includes some famous Colin McRae cars like his championship winning Subaru and his 2001 Ford Focus.
In November 2008, Codemasters unveiled a sequel to the successful Colin McRae: Dirt; it was released in September 2009. The game is available on PlayStation 3, PlayStation Portable, Wii, Xbox 360 Nintendo DS, and Microsoft Windows. The game is built upon an improved version of the EGO game engine that powered the previous game, as well as a comprehensive online mode. The game was a dedication to Colin McRae featuring videos and a special tournament in his honor.
A typical rally course consists of a sequence of relatively short (up to about 50 km (31 mi)), timed "special stages" where the actual competition takes place, and untimed "transport stages" where the rally cars must be driven under their own power to the next competitive stage within a generous time limit. Rally cars are thus unlike virtually any other top-line racing cars in that they retain the ability to run at normal driving speeds, and indeed are registered for street travel. Some events contain "super special stages" where two competing cars set off on two parallel tracks (often small enough to fit in a football stadium), giving the illusion they are circuit racing head to head. Run over a day, a weekend, or more, the winner of the event has the lowest combined special and super special stage times. Given the short distances of super special stages compared to the regular special stages and consequent near-identical times for the frontrunning cars, it is very rare for these spectator-oriented stages to decide rally results, though it is a well-known axiom that a team cannot win the rally at the super special, but they can certainly lose it.
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.
