Williams launch their new FW31
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 tire 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 tires 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 tires as another significant rule change for 2009. “Finding the optimum weight distribution to optimize tire performance will also be a high priority going into 2009 and KERS will be the next contributor to race performance. “ Michael confirmed.
The introduction of Kinetic Energy Recovery Systems (KERS) in 2009 is not an obligatory element of the regulations, but may provide an opportunity for teams to gain competitive advantage. The amount of energy that can be recovered and used may increase in future regulations, but the level set for the technology’s introductory year, set against considerations of weight and reliability, make the initial advantages less than gains to be achieved through aerodynamics and mechanical dynamics. Sam Michael contextualized this view, saying, “KERS in 2009 could be worth between 2/10ths and 3/10ths of a second per lap. However, once aero performance converges, KERS could start to become a greater performance differentiator and if the regulations give more scope to the technology, it could be worth anything up to a second a lap and it will be needed to win Grands Prix. The key decision for us with our system is to carefully balance the potential performance advantage with our ambition to improve an already strong reliability record from last season.”
Nico Hülkenberg, the first of the AT&T Williams team drivers to experience the FW31 felt confident in the car’s abilities, but naturally reflected on the difference from its predecessors. “Straight away the new car feels okay, I feel comfortable in it and for a new car, we have also had a trouble-free morning technically, which is important. Of course everyone will want to know how it compares to the 2008 car and what the impact of the rule changes are from a driver’s point of view. In truth, I cannot say too much after a few laps, because the track is 100% new to me, I have never run here and also it is pretty wet, so I have no baseline for comparison – if we were at Jerez or Barcelona in the dry, I could be a little more specific. But the important thing for today is simply to make sure we run through all the checks of the basic systems on the car and confirm everything is working as it should. So far that is the case and we can be happy.”
The front wing becomes lower (75mm from 150mm) and wider (up from 1400 to 1800mm - the same width as the car) with driver-adjust able flaps. Drivers will be allowed to make two wing adjustments per lap, altering the wing angle over a six-degree range.
The rear wing becomes taller (up 150mm to bring it level with the top of the engine cover) and narrower (750mm from 1000mm).Also at the back of the car, the diffuser has been moved rearwards, its leading edge now level with (rather than ahead of) the rear-wheel axle line. In addition, the diffuser has been made longer and higher, all changes that will reduce its ability to generate downforce.

Dominic Reilly, the team’s Head of Marketing, commented, “Philips has demonstrated, through its excellent track record of sponsorship execution, that their Formula One engagement has made a real difference to the bottom line. As a consequence, Philips have upgraded from the Shaving Division to the whole of its Consumer Lifestyle group. In consideration of this, Philips will have substantially increased livery on the 2009 race car.”
Since announcing this new agreement in late 2008, a further nine agreements with existing partners have been signed, including Allianz, PPG, Oris, MAN and the recent announcement of another upgraded and extended agreement with Randstad, who now become one of the team’s senior partners as confirmed last week.
Adam Parr, Williams Chief Executive said, “We are very grateful for the loyalty and steadiness of purpose of our partners. We never take anything for granted, but our 2009 and 2010 budgets are in place thanks to the support of our partners as well as the increased revenues from FOM and the work being done by FOTA and the FIA to reduce costs. It is now our responsibility to make sure that our partners and the many other people who support the team enjoy a return on that investment.”
Turning to the prospects for 2009, Frank Williams said, “It will be a very interesting year ahead. The new aero rules mean a different approach to the cars in a number of areas. However, by the time we get to Melbourne, I would expect the usual suspects to still be dominating the top two positions. More importantly, I hope Williams will have made a significantly large step forward with the FW31.”
