The causes of rallies vary. Short-term rallies can result from news stories or events that create a short-term imbalance in supply and demand. Sizeable buying activity in a particular stock or sector by a large fund, or an introduction of a new product by a popular brand, can have a similar effect that results in a short-term rally. For example, almost every time Apple Inc. has launched a new iPhone, its stock has enjoyed a rally over the following months.
Pacenotes are a unique and major tool in modern rallying. Television spectators will occasionally notice the voice of a co-driver in mid-race reading the pacenotes over the car's internal intercom. These pacenotes provide a detailed description of the course and allow the driver to predict conditions ahead and prepare for various course conditions such as turns and jumps.
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.
Such was Porsche’s commitment to making the ultimate go-anywhere racing car that the 959, with its domesticated version of the 962’s racing engine, was years ahead of the game in terms of technological development. It was said that Nissan chief engineer Naganori Itoh took inspiration from the Porsche 959 when developing the hi-tech four-wheel-drive system of the R32 Skyline GT-R. And that’s some lineage indeed.
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.
These events were road races in all but name, but in Italy such races were still allowed, and the Mille Miglia continued until a serious accident in 1957 caused it to be banned. Meanwhile, in 1981, the Tour de France was revived by the Automobile-Club de Nice as a different kind of rally, based primarily on a series of races at circuits and hillclimbs around the country. It was successful for a while and continued until 1986. It spawned similar events in a few other countries, but none survive.
Between 1997 and 2010, the regulations mandated that World Rally Cars must have been built upon a production car with a minimum production run of 2500 units. A number of modifications could be made including increasing the engine displacement up to 2.0L, forced induction (including an anti-lag system), addition of four wheel drive, fitment of a sequential gearbox, modified suspension layout and attachment points, aerodynamic body modifications, weight reduction to a minimum of 1230 kg and chassis strengthening for greater rigidity. The maximum width was set at 1770 mm while front and rear tracks shouldn't exceed 1550 mm.
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.
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).
In the wake of the ever more advanced rally cars of the 21st century is a trend towards historic rallying (also known as classic rallying), in which older cars compete under older rules. This is a popular sport and even attracts some previous drivers back into the sport. Many who enter, however, have started their competition careers in historic rallying.
In many rallies, including those of the World Rally Championship (WRC), drivers are allowed to run on the stages of the course before competition and create their own pacenotes. This process is called reconnaissance or recce. During reconnaissance, the co-driver writes down shorthand notes (the pacenotes) on how to best drive the stage. Usually the drivers call out the turns and road conditions for the co-drivers to write down. These pacenotes are read aloud through an internal intercom system during the actual race, allowing the driver to anticipate the upcoming terrain and thus take the course as fast as possible.
Porsche 911s have appeared in rally competition since the beginning of their production, but rally 911s haven't been a common sight since the 1980s. Thankfully R-GT fixed that, allowing the 996 and 997 GT3 to be homologated for rally. UK dealer Tuthill Porsche campaigns a 997 GT3 Cup in the World Rally Championship and its's exactly as great as you think it is.
What do you do when you're Mercedes-Benz in the late 1970s and you want to go rallying, but your sportiest car is a luxury cruiser that isn't very sporty? You take the C107 SLC Coupe rallying anyways. In an era dominated by nimble cars like the Lancia Stratos and Ford Escort, the 450SLC must have been quite a sight, but Mercedes actually had some competition success. Mercedes won the 1978 South American rally and was able to get 4th place in a Manufacturers Championship.
His first WRC event was the 1987 Swedish Rally behind the wheel of his Nova, and again two years later, driving the Sierra and finishing 15th overall. Later that year, he finished 5th overall at Rally New Zealand in a rear wheel drive Sierra Cosworth. By 1990 McRae was driving a Sierra Cosworth 4x4 and achieved sixth place in that year's RAC Rally, despite several accidents. 1991 saw McRae turn professional as he was signed by Prodrive boss David Richards to his Subaru team in the British Rally Championship for an annual wage of approximately £10,000. McRae was British Rally Champion in both 1991 and 1992, soon graduating to the Subaru factory team at World Rally Championship level. 1992 also saw Colin McRae make his début in the British Touring Car Championship, with a one-off appearance for the Prodrive-run BMW factory team at the Knockhill round. In the second of the two races of the event, McRae collided with Matt Neal. Race officials found McRae to have caused an avoidable collision and subsequently disqualified him.
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.
Although there had been exceptions like the outlandish Ford V8 specials created by the Romanians for the 1936 Monte Carlo Rally, rallies before World War II had tended to be for standard or near-standard production cars, a rule supported by manufacturers because it created a relatively even playing field. After the war, most competing cars were production saloons or sports cars, with only minor modifications to improve performance, handling, braking and suspension. This kept costs down and allowed many more people to afford the sport using ordinary family cars, so entry lists grew into the hundreds.
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.
