Jun.16 (GMM) Williams is still yet to set a date for the debut of its KERS system in 2009.
The Grove team said earlier this year that at least six or seven races would pass until it deployed the energy re-use technology."We're still pushing as hard as we can to get our KERS onto the FW31," technical director Sam Michael said this week, ahead of the British grand prix, round eight of the world championship.Williams took a novel approach to the KERS implementation, buying into a hybrid power company and designing a mechanical flywheel solution that is said to be safer and less expensive than the more popular battery-based systems."We're developing both the flywheel and the battery systems," Michael clarified, "but we've put more effort into the flywheel programme over the last 18 months and we're making progress on reliability every week."We want to race it as soon as possible, but we're not going to put it on the car until it's fully reliable," the Australian added.
