McLaren boss Zak Brown has dismissed rumours that the team will ditch Honda in favour of a return to Mercedes next season.
The Woking team are yet to secure their first World Championship point after a disastrous start to the 2017 campaign which has been blighted by multiple breakdowns and retirements from both McLaren drivers.
As a result, there have been strong calls from McLaren to end their damaging relationship with engine supplier Honda, but Brown has denied that they will seek a reunion with former partners Mercedes.
"No Mercedes in the back of our car," Brown said.
"Obviously the Formula 1 results right now are frustrating but the culture’s great, the people are great and the things that we’re doing, we’re being brave and taking some big decisions.
"It’s great working with the executive committee, they’re providing some great leadership for the whole organisation. So we’re happy here.
"We’re frustrated we’re not winning Formula 1 races – that’s not going to change overnight – but we’re working hard and it’s going to be sweeter when we do win."
