1968 brought the first of a series of British-organised intercontinental rallies, the Daily Express London-Sydney Marathon, which attracted over 100 crews including a number of works teams and top drivers; it was won by the Hillman Hunter of Andrew Cowan/Brian Coyle/Colin Malkin. Not to be outdone, the rival Daily Mirror sponsored in 1970 the London-Mexico World Cup Rally, linking the stadia of two successive football World Cups, on a route that crossed Europe to Bulgaria and back before shipping out from Lisbon to Rio de Janeiro, after looping around South America, and a run through some of the most frightening sections of Peru's road race, the Caminos del Inca, they wrap it up being shipped to Panama and a final run up Central America. The Ford Escort of Hannu Mikkola and Gunnar Palm won. These were followed in 1974 by the London-Sahara-Munich World Cup Rally, and in 1977 by the Singapore Airlines London-Sydney Rally.
In Germany, the Herkomer Trophy was first held in 1905, and again in 1906. This challenging five-day event attracted over 100 entrants to tackle its 1,000 km (620 mi) road section, a hillclimb and a speed trial, but sadly it was marred by poor organisation and confusing regulations. One participant had been Prince Henry of Austria, who was inspired to do better, so he enlisted the aid of the Imperial Automobile Club of Germany to create the first Prinz Heinrich Fahrt (Prince Henry Trial) in 1908. Another trial was held in 1910. These were very successful, attracting top drivers and works cars from major teams – several manufacturers added "Prince Henry" models to their ranges. The first Alpine Trial was held in 1909, in Austria; by 1914, this was the toughest event of its kind, producing a star performance from Britain's James Radley in his Rolls-Royce Alpine Eagle.
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.
The funeral for Colin and Johnny took place on 26 September at Daldowie Crematorium near Glasgow, conducted by the Rev Tom Houston, who had married the McRaes, and the Rev Steven Reid, chaplain at Johnny's school. An address was given by Robbie Head, a former rally driver and commentator who was a close friend of McRae's, with the Rev Houston giving the benediction. McRae's niece and nephews performed the tune Highland Cathedral, a popular funeral song. The song "(Sittin' on) the Dock of the Bay" by Otis Redding, a favourite song of McRae's, was played when the family entered the chapel (coincidentally, Redding himself also died in an air crash). The Proclaimers' song "I'm on My Way" was played when they left. Colin and Johnny McRae were cremated in the same coffin. Among the attendees at the funeral were fellow Scottish racing drivers Jackie Stewart and Dario Franchitti.
