Martin Whitmarsh says McLaren will continue to use Mercedes engines for the foreseeable future -despite becoming a customer team for the first time in over two decades.
Mercedes sold their stake in McLaren after purchasing Brawn GP in 2010 and from next season the Woking-based team will have to pay for their engines.
That led to speculation the team could seek an alternative engine supplier with rumours of a link up with Honda - whose engines McLaren last used in 1992 - when the new 1.6 turbo regulations are introduced in 2014.
Whitmarsh, though, says the team have no intention of switching and want to continue their relationship with the German-marque.
"It is going to be McLaren Mercedes for quite a few years to come," he told the Daily Mail.
"It is a good partnership and it works well. We've been together for 18 years and it is going to continue for quite a few years to come.
"I think we have got a very good deal with them, but I think more importantly than that is we have got a good partnership.
"Obviously I've been involved with Mercedes personally. I ran the engine side so we know the people, and we are proud to be part of the Mercedes-Benz family."
