McLaren released the MP4-26 today in Berlin.
One of the interesting things is that they started with a somewhat unassembled car, and then put it together in front of everyone. Though, Marvin Whitmarsh has said some of the internal pieces were deliberately obscured or replaced so as to not give away all their secrets.
