The Woking-based outfit has been reunited with the Japanese manufacturer with which enjoyed its more successful era at the end of the 1980s and the start of the 90s.

But the partnership has endured a difficult start and McLaren is yet to score a point in four races and has been plagued by reliability issues.

Mark my words! We'll win together and, when we do so we'll do so dominantly. Ron Dennis

Dennis admitted McLaren has a "mountain to climb", but remains convinced the team will return to winning ways.

"McLaren-Honda will see the fruits of all that effort," Dennis told the official Formula 1 website in an interview.

"Mark my words! We'll win together and, when we do so we'll do so dominantly.

"I don't want to put a timeframe on that prediction, because that would be foolhardy.

"But whenever I walk around the McLaren Technology Centre, speaking as I do to our people at the sharp end what I encounter is fierce determination, burning ambition, unshakable confidence and unbreakable esprit.

"That makes me very proud. We're pulling together, all of us, and we know we'll get there."

Dennis reckons Honda's innovative approach to engine manufacturing will eventually be something that rivals will see as reason for concern.

"When it comes to power unit design and manufacture, Honda leads the way - globally," he said.

"Their managers and engineers know their Formula 1 power unit isn't yet the best, but it will be. They know that and so do we. So do our drivers - that's why they want to drive for us.

"And that's why a lot of other drivers want to drive for us too, as it happens. So, in answer to your question, no, I'm not at all concerned that Honda may be taking an innovative path when it comes to the design of our Formula 1 power unit.

"In the long run, ultimately, in fact, I think that fact is likely to be more of a concern for our competitors."
