Sauber has a problem on colder tracks

Sauber will be hoping that it will remain sunny for the rest of the year, as the C37 doesn't appear to function correctly in cooler environments.

"If it's cold, we have a problem," Marcus Ericsson told Formel1.de.

This problem was apparent ever since pre-season testing in Barcelona, where the icy track became a big liability.

Case in point: Shanghai last weekend where the track was twelve degrees. Sauber's finishes? P19 and P20.

Ericsson scored Sauber's only points of the season so far in sunny Bahrain, where the temperature was 27 degrees. The Swede does think that it shouldn't be an issue for much longer, as by the time the next cold Grand Prix comes around, the team will have collected enough data to have figured the problem out.
