Ammermuller could lose F1 test seat

(GMM) Michael Ammermuller is not guaranteed a seat within Red Bull's Formula One family in 2007.

The German rookie moved into the Friday role amid the Christian Klien reshuffle late last season, but the publication 'Eurosport MotorMagazin' suggested that a test ride next year has not yet been sealed.

Meanwhile, Ammermuller is expected to contest at least a couple of races for 'Team Germany' in the current winter-based A1 GP series.
