Williams-Toyota FW21

This is the Williams-Toyota FW31, the AT&T Williams contender for the 2009 Formula One season. The team says this new car is the first major clean-sheet design in the past 30 years, mainly thanks to the massive changes in the sport’s technical and sporting regulations. The technical regulation changes mainly focus on reducing the role of aerodynamics and making overtaking easier, while the sporting regulations changes mainly focus on increasing racecar reliability and reducing competition costs.

According to Technical Director Sam Michael, the new aerodynamic regulations will have the most impact on lap times this year, especially in the first two thirds of the season. Teams will have to find the optimum weight distribution to maximize the performance of the new slick tyres. He also added that KERS could be worth between 2/10ths and 3/10s of a second per lap. KERS would not have such a big effect at first but later once aero performance between the teams converge, KERS will become more important as a differentiator.
