McRae rejoined Prodrive for the 2004 24 Hours of Le Mans where he took third place in the GTS class, and ninth position overall in a Ferrari 550-GTS Maranello partnering Darren Turner and Rickard Rydell. Fellow countryman, and Le Mans winner Allan McNish commented that "Colin has adapted far better than people expected" to endurance sportscar racing.
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 February 2015, The National Film & Television School in England premiered one of their graduating films called "Group B" directed by ex-rally driver Nick Rowland. The film, set during the last year of the Group B class of rally tells the story of a young driver having to face a difficult comeback after a 'long and troubled absence'. The young driver is played by Scottish actor Richard Madden, and his co-driver played by Northern Irish actor Michael Smiley.
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.
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.
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.
"bring together," c.1600, from French rallier, from Old French ralier "reassemble, unite again," from re- "again" (see re-) + alier "unite" (see ally (v.)). Intransitive meaning "pull together hastily, recover order, revive, rouse" is from 1660s. Related: Rallied; rallying. Rally round the flag (1862) is a line from popular American Civil War song "Battle Cry of Freedom."
