McLaren will usher in a new era this week by announcing that Fernando Alonso will re-sign and their cars will be powered by Renault next season.
After months of negotiations, the landmark news will be confirmed in Singapore, ahead of this weekend's night race around the city-state's illuminated streets.
Sportsmail understands that subject to any unexpected late hitch, the new bosses of Britain's most successful Formula One team have pulled off the double success by agreeing to ditch their current partners Honda, whose engines were woefully underpowered and grossly unreliable.
Changing engine suppliers is everything that Alonso hoped for. He had made being able to drive a competitive car next season the key factor in deciding whether to carry on at McLaren, and possibly even Formula One itself.
Retaining the double world champion Spaniard is a major boost for the sport, as well as for Alonso's bank balance. The terms of his new contract are believed to be similar to his existing package, just north of £20million annually.
