Williams Team drivers Nico Rosberg and Kazuki Nakajima reported earlier in the week that the unique KERS system for the Williams FW-31 would not be available for use in the cars for at least the first 6 races of the season.
A spokesman for the team confirmed the report, saying "we're not going to be using it in Australia but not clear when we will use it."
Unlike the other teams on the grid for this year, Williams decided to go with a mechanical flywheel technology for their KERS device.
Williams purchased a large stake in a hybrid company, using previous work and outside sources to build their KERS device. Every other team has been testing with an electrical KERS setup, to some mixed success.
Not having KERS may not be a major blow to the team though. Nakajima was quoted that he "never pressed the button" during testing of the Toyota-powered FW-31 for the 2009 season.
Nico Rosberg had no comment pertaining to usage of the temporary boost, but also did not express any concern for racing without the system.
The team spokesman went on to say the main focus of the team right now is optimizing performance "weight distribution, balance and setup for the slick tyres."
