Honda has confirmed that it will return to Formula 1 in 2015 as engine supplier to McLaren.
The Japanese manufacturer has not competed in F1 since shutting its works team at the end of 2008, but has decided to return as a result of the change to 1.6-litre turbocharged V6 engines.
It has been known to have been in talks with McLaren for some time and has already made significant progress with design work on its new engine.
Honda previously supplied McLaren with engines from 1988-1992, winning both the drivers' and constructors' championship four times.
