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.
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.
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.
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.
