While McLaren have an option in their contract to renew their engine deal with Mercedes for 2014 and 2015, the talk around the paddock is that the team is only expected to take up the option for 2014. But I fail to understand why a team would go with one engine supplier in the first year of a major rule overhaul and then switch after one year when the rules would not have changed that much or not at all to another engine.
Honda's re-entry into the sport will certainly make the sport stronger and their return to the sport has vindicated the change of engine formula to the smaller, more efficient turbo charged units with new and improved Energy Recovery Systems which have more real world application.
They returned to the sport in 1983 as an engine supplier for teams like McLaren, Williams, Tyrell and Spirit. Honda powered five consecutive drivers world championships from 1987 to 1991, out of which four on the trot were won with McLaren. All of Ayrton Senna's world championships were in at the wheel of a McLaren Honda, while arch rival and team mate Alain Prost took the title in 1989. The only other driver to taste success with Honda in that period was Nelson Piquet in the Williams Honda in 1987.
1988 was the last year of the turbo charged engines and the championship winning combination was a McLaren Honda. Fast forward to 2015 and it seems like we might just get to see the same Red and White colours of the McLaren Honda return to the grid, actually maybe not the Marlboro colours, but something close.
