McLaren are to use Honda engines as the Japanese company returns to Formula 1 for the first time since 2008.
Honda pulled out of F1 after years of poor results with its own team, which subsequently won the championship as Brawn in 2009 and is now Mercedes.
But the engine manufacturer has decided to return because of next year's introduction of turbo engines featuring energy recovery technology.
McLaren are first expected to race with Honda engines in 2015.
McLaren has a contract with Mercedes with options for the team to renew for 2014 and 2015. McLaren are expected to take up only the first of those options.
McLaren, with Honda as an engine supplier, dominated F1 in the late 1980s and early 1990s, winning four consecutive world drivers' championships with Ayrton Senna and Alain Prost, as well as the corresponding years' constructors' titles.
In 1988, McLaren with Senna and Prost enjoyed the most successful season in F1 history, winning 15 of the 16 races.
Honda also dominated the mid-1980s with Williams, winning the 1987 drivers' title with Nelson Piquet and the 1986 and 1987 constructors' championships.
Honda would become the fourth road-car manufacturer supplying engines in F1, alongside Mercedes, Renault and Ferrari (Fiat).
