I agree with Vasco: The MP4-21 has been the most reliable machine to date.
I agree with Tom: Kimi and Juan Pablo have said the team is tuning the engine down so it lasts, even the new specification (we have to remember the failure of the first design of the Mercedes V8 engines in the pre season).
But I think McLaren's problem is suspension. No-keel front suspension is VERY tricky... last year the team was able to master it, this year they are not able to control it.
I want to fuel the fire in my very first post, Team McLaren Mercedes problem there are more chiefs in the team. I like Ron, but it must be a pain in the head

to work with him, Haug, Withmarsh and Mansour Ojjeh.
