The F399, fitted with a modified rear wing, completed today 57 laps of the Fiorano track (almost 200 km.) with a best laptime in 1.02.299. Michael Schumacher drove the car just to learn its behavior. He didn't face mechanical problems. Luca Badoer completed 33 laps with an F300 to test some components. Best laptime: 1.03.547. Tomorrow Schumacher will test the F399 again in Fiorano.
