Sauber's Kaltenborn rubbishes Wehrlein insinuations

Sauber boss Monisha Kaltenborn has lashed out against stories alleging that reasons beyond fitness issues are keeping Pascal Wehrlein from driving.

The German pulled out of the Australian Grand Prix after judging that his fitness level was not up to driving a new-spec F1 car around Albert Park for 56 laps.

Wehrlein's carsh at the ROC in Miami earlier this set was a set-back to his preparation and led to limited mileage with Sauber's new C36 in pre-season testing at Barcelona.

Kaltenborn insists the only issue affecting her driver is one centered around his fitness, with all other speculation just fantasy.

"I have to disappoint you there, the story is actually very straightforward and it might just not be good enough for some people to sell it better," Kaltenborn told Autosport when questioned about the skepticism expressed by pundits over Wehrlein's inability to race.

"The facts are - and it's really the way it is - he had this accident in America, and most of us saw the pictures.

"You see it's quite an impact, particularly his back suffered there. There was a lot of load on the back. These kinds of things you have to take seriously.

"Since that accident he got very clear medical instructions, under which he could not do very much training.

"It surprised us he actually got medical approval to be able to be in the car again that quickly, and the doctors also told us it's the result of having such a fit condition.

"We put him in the car step-by-step, never a whole day [of testing] but half-days. But we all know there's something he's missed out, which he has to catch up."

Wehrlein has stayed back in Europe in order to focus on his training. A decision about racing in Bahrain next week will be made in the coming days, with Ferrari reserve driver Antonio Giovinazzi remaining at Sauber's disposal.

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
