McLaren and Honda have formally agreed to part ways at the end of the 2017 season. The future of the deal has been cast in major doubt over the last couple of weeks, and it was expected that the announcement of the divorce would be made this week.
Honda re-entered the sport in 2015 to supply McLaren with power units, with the vision of achieving the success of the late 1980's, when McLaren-Honda dominated the sport. However, three seasons later, McLaren has not yet got close to claiming a podium finish.
It is also reported that McLaren has signed a three-year deal with Renault and will take up a supply from the French manufacturer until the end of 2020, right before the next set of engine regulations will come into the frame. With Fernando Alonso previously claiming he would not stay at McLaren if they continued with Honda, it is now suggested that the Spaniard will stay on with the Woking team.
F1's bosses have been meeting recently with the hope of securing Honda in F1 for the long-term. It is therefore likely that Toro Rosso will be given a deal with Honda and Carlos Sainz will depart the Red Bull junior squad to sign for the Renault team.
