In the first three races we witnessed three different pole-sitters: Lewis Hamilton, Felipe Massa and Robert Kubica. If there will be a fourth different pole-sitter in Spain, it will be the first time since 1983 that the first four races have produced four different drivers on pole. At the time these were Keke Rosberg, Patrick Tambay, Alain Prost and Rene Arnoux.
The count of consecutive wins for these two teams, which started at the 2006 Brazilian Grand Prix, needs an update. It reached 21 races in Bahrain, and to find a longer sequence of wins by only two teams we have to go back to 1991-1992, when Williams and McLaren were the only winners between the 1991 Mexican Grand Prix and the 1992 Hungarian Grand Prix - a total of 22 races.
The last non-McLaren/Ferrari win was the one scored by Honda in Hungary 2006 with Jenson Button.
