Wednesday 25 March at 16:29 : Mar.25 (GMM) BMW-Sauber may wait until the day of qualifying to decide if it will use new KERS technology in the Australian grand prix, its test driver said on Wednesday

Christian Klien, also reserve driver for the Swiss based squad in Melbourne and elsewhere on the 2009 calendar, confirmed to the Austrian newspaper Kleine Zeitung that the team will make decisions about KERS on a race-by-race basis this season

While team boss Mario Theissen is a staunch supporter of the newly allowed braking energy re-use technology, the power boost advantage is at some circuits offset by the extra weight and the impact on tyre wear

Austrian Klien, 26, said: "For Australia we will decide only on Friday, or perhaps even Saturday."n
