McLaren became the second team to unveil its 2010 car last week, when the covers came off the striking-looking MP4-25.
Team principal Martin Whitmarsh looked ahead to the new season and talked about the new rule changes, especially in relation to tyres.
He said: “One of the big important issues is we have new front tyres and we have heavy cars with heavy fuel loads.
“It sounds minor but the performance of those tyres and the rate of degradation of those tyres will have a massive impact on how those races unfold and what is the best strategy.
“Frankly we don’t have that information at that moment. So on the one hand, we all want clear regulations and we want to tell people how we are going to go motor racing.
“But we will be in much better shape to make those decisions if we had good experience with the tyres and we could then gauge how these races typically play out given the tyres we have.”
