BMW, Renault and Williams launch 2009 F1 cars

Perpetual front-runners Ferrari and McLaren-Mercedes have already revealed their contenders for the 2009 Formula 1 World Championship, and as the weeks remaining until the kickoff of the new season in Melbourne tick away, more and more teams follow suit. This week the new debuts include the BMW, Renault and Williams teams. The cars, bearing the simple code names that mark them as true race cars, are dubbed the BMW F1.09, Renault R29, and Williams FW31. Together with Toyota, which revealed its TF109 car last week, these comprise the 'best of the rest', or the teams most likely to contend for whatever remaining points are left after Ferrari and McLaren-Mercedes do their best to take the championship - or at least that's how things are expected to shake out at this point.
