Jul.19 (GMM) BMW-Sauber's first track test of a KERS system for 2009 went off without a hitch, the German magazine Auto Motor und Sport reports.

The event, on July 15, took place at the German carmaker's own Miramas test circuit, with Marko Asmer at the wheel over 48 kilometres.

It is now well known that Red Bull's KERS testing resulted in a visit to its Milton-Keynes factory of the local fire department, while Honda had some teething trouble when its initial track testing - with an old car - took place on an airfield runway and subsequently at Silverstone.

BMW-Sauber's KERS track testing will step up a notch next week when Christian Klien takes to the wheel of a modified F1.08 chassis.

"It will be obvious that we are running the systems," technical director Willy Rampf said. "But the car will have nothing to do with the car for next year."
