Formula One team McLaren is to end its partnership with its Honda at the end of the 2017 season, the British team confirmed Friday.

McLaren and the Japanese manufacturer joined forces in 2015, renewing a partnership that had yielded four consecutive constructors’ titles in the late 1980s and early 1990s, but the team has struggled to compete with an engine that has lacked power and reliability.

Star driver Fernando Alonso has suffered eight retirements this season to date, and the team currently lies second to last in the 2017 constructors’ championship.

“For a combination of reasons our partnership has not flourished as any of us would have wished,” McLaren’s executive director Zak Brown said in a statement on the McLaren website.

“It is certainly not for the want of effort on the part of either Honda or McLaren, but the time has come to move ahead in different directions.

“As fellow racers, we hope to see the great name of Honda get back to the top – our sport is better for their involvement. I know this view is shared by everyone in the sport.”
