After completing 17 laps this morning in the hands of AT&T Williams' test driver, Nico Hulkenberg, the team was satisfied with initial progress. Technical Director, Sam Michael, said, "This morning has been full wet, but the weather hasn't really affected what we wanted to do, because our goal has been to get the car out on track, check all the systems work, be sure parts aren't touching each other, nothing is burning, and that's all proved to be okay. It would be good to get some dry running, and the weather should allow this later in the week. In terms of first impressions of the car, we of course haven't spent any time on set-up or performance work yet, that'll all come later, but so far the car is running fine."

The Williams-Toyota FW31 is the first major clean-sheet car design for perhaps 30 years, driven by a wholesale change in Sporting and Technical Regulations. The new Sporting Regulations are intended to increase car reliability and further reduce costs, while the changes to the Technical Regulations have three objectives - reducing the role of aerodynamics in the car's performance, making overtaking easier and keeping lap times in check. These changes have had significant implications both on the appearance of this season's race car and in shifting its performance baseline.

Sam Michael reflected, "The changes in the aerodynamic regulations are the most profound and will have the most impact on lap time. There are many immediate visual changes, but also many smaller reductions around the car through new regulation wording and exclusion zones. Starting at the front, the front wing end plate design has changed as the interaction with the front tyre is completely different, and important to control. There are no longer large barge boards - although we managed to squeeze a small one in. The engine cover no longer has the traditional chimneys and louvers on top for cooling, and that has forced a higher and wider exit at the rear in order to provide an effective exit for hot air. Of course the re-introduction of slick tyres is another significant change as it has an influence on the overall dynamics of the race car. Finally, of course, the introduction of KERS is another aspect to the technical picture for the year ahead."

Michael went on to explain how the changes in aerodynamic rules, which see a much reduced rear wing geometry and conversely, a considerably wider front wing profile, with the front wing flap angle adjustable by the driver in the cockpit, would be the competitive focus for all the teams for much of the year ahead. "Aerodynamics is likely to be the key to the first two thirds of the season ahead," he said, while rating the change to slick tyres as another significant rule change for 2009. "Finding the optimum weight distribution to optimise tyre performance will also be a high priority going into 2009 and KERS will be the next contributor to race performance. " Michael confirmed.
