McLaren and Honda agree to end partnership

McLaren has reached agreement with Honda to be released from their partnership and switch to Renault power from the 2018 Formula 1 season

Honda's return to F1 with McLaren has been disastrous since it came back to the grid in 2015, with a lack of performance and constant reliability problems holding the once-successful partnership back during its second iteration.

The relationship has become so fractious during 2017 that it became clear a split was likely, with Renault emerging as McLaren's only realistic alternative.

Sources close to the deal have confirmed that McLaren has agreed a three-year deal with Renault, taking it to the end of the current F1 engine regulations cycle in 2020.
