Mario Theissen is leaving Formula One because he will remain BMW's motor
sport director in 2010 and beyond.
The 57-year-old German, who entered the sport with BMW in 2000 and became
Sauber's team boss in 2006, had hinted he might stay with the Hinwil based
squad in the wake of BMW's F1 withdrawal.
But he told Switzerland's Blick daily: "I will also be responsible for
the motor sport activities of BMW in the future."
It is reported that BMW will on Saturday announce its motor sport programme
for 2010, amid rumours a Le Mans foray is possible.
Theissen said in other German reports: "Peter Sauber now takes control and
will lead the (F1) team.
"For me it is an end and a new era (for Sauber) begins."
