McLaren’s executive director Zak Brown says the team is nearing its limit with engine supplier Honda, as its troubled partnership continues.
Since rejoining forces in 2015, McLaren has failed to score a podium finish and is currently last in the 2017 constructors’ standings – the only team yet to score a point.
Over the last three seasons, poor reliability and a lack of power with Honda’s power units have severely hampered McLaren’s results.
With Honda’s planned Canadian GP upgrade being delayed, Brown says the team has “serious concerns” about its chances of winning titles with the Japanese manufacturer.
“The executive committee have now given us our marching orders,” he told Reuters. “We’re not going to go into another year like this, in hope.
“I don’t want to get into what our options are. Our preference is to win the world championship with Honda.
“But at some point you need to make a decision as to whether that’s achievable. And we have serious concerns.
“Missing upgrades, and upgrades not delivering to the level we were told they were going to, you can only take that so long. And we’re near our limit.”
Brown admitted Honda seems “a bit lost” with its current V6 Turbo power unit, adding McLaren is now entering a “fork in the road” when it comes to considering its future engine supplier.
