Sauber Formula 1 CEO Monisha Kaltenborn has parted company with the team with immediate effect ahead of this weekend’s Azerbaijan Grand Prix.
Kaltenborn has worked with Sauber since 1998 and was appointed the CEO of its motorsport interests in 2010, before becoming F1’s first female team principal two years later.
Kaltenborn played an instrumental role in keeping Sauber afloat amid years of financial uncertainty, with its long-term future being secured following a takeover by Longbow Finance last summer.
The new investors kept Kaltenborn on in her role as CEO and team principal, with Sauber going on a significant recruitment drive in the closing stages of last year. Sauber also recently announced a new engine tie-up with Honda from 2018.
However, news of Kaltenborn’s departure from Sauber emerged on Wednesday morning, just days before the next grand prix in Azerbaijan.
The team is yet to issue an official statement regarding Kaltenborn’s exit, but an announcement is expected later on Wednesday.
According to a report from Autosport‘s Dieter Rencken, Kaltenborn could be replaced as team boss at Sauber by Colin Kolles, who has previously been involved with the Caterham, HRT and Force India projects in the past among others.
Kolles’ most active involvement in motorsport currently is his ByKolles LMP1 team in the FIA World Endurance Championship, but this is set to withdraw from the remainder of the season after the July 16 round at the Nürburgring.
Sauber currently sits ninth in the F1 constructors’ championship with four points from the opening seven races of the season, all scored by Mercedes junior Pascal Wehrlein.
Defending MotoGP series champion Marc Marquez underwent a second surgery Monday after a titanium plate inserted in his fractured right arm sustained damage. The Repsol Honda Team said in a statement that it’ll be two days before the recovery period is determined.
Marquez was injured during a crash in the July 19 season opener. He underwent an initial surgery July 21 in Barcelona, and doctors said there was no nerve damage.
The eight-time champion was cleared to race in the season’s second event Jerez. But Marquez decided to skip the July 26 race after experiencing discomfort while riding the No. 93 bike in a July 25 practice.

He had planned to race in Sunday’s grand prix at the Automotodrom Brno in the Czech Republic in hopes of returning to defend his title. His status for Sunday apparently will be unclear until at least Wednesday.
In a statement Monday, the team said the titanium plate in Marquez’s right arm successfully was replaced after stress accumulation. Marquez will stay in the hospital for two days recovering.
Dr Xavier Mir, who performed the surgery at the Hospital Universitari Dexeus, said in the release that “Marc Marquez underwent surgery 13 days ago and today he returned to the operating room. The first operation was successful, what was not expected was that the plate was insufficient. An accumulation of stress in the operated area has caused the plate to suffer some damage, so today the titanium plate has been removed and replaced by a new fixation.
“The rider has not felt pain during this period. He has always followed the medical advice given and the feeling from his body. Unfortunately, an overstress has caused this issue. Now we have to wait 48 hours to understand the recovery time.”
