Sauber introduced a new design concept this year by introducing very slim sidepods. The new concept is likely to provide more aerodynamic gains as the drag due to bulky sidepods will be reduced but there had been questions of whether the slim sidepods could house radiators that would be adequate for cooling.

But, despite all the speculation Peter Sauber has revealed that everything on C32 worked fine during the Jerez test and even said that they didn't have any problem with engine and KERS cooling.
