McLaren I found interesting. Martin Brundle made the very good point in commentary that the car didn't actually look like a proper dog at all during the race — it seems to corner well and doesn't lack straight-line pace compared to the opposition, especially when you look at Hamilton's excellent use of KERS to overtake. Yet neither did it seem as if they were sandbagging, so it's all a bit of a puzzle.

That is an interesting conundrum isn't it. To be fair even during testing Hamilton was saying that the car felt fine to drive, it just wasn't getting the times that everyone else was.
I'd hazard a guess that some of the other cars that were getting faster times in the more controlled conditions of testing and qualifying, perhaps found it hard to consistently achieve that performance in the more changeable conditions of the race. Maybe the less aerodynamically optimised McLaren actually copes better with the changing fuel loads, tyre wear, the turbulent air following other cars, etc.
