Sauber C31 – cooling options tested during Winter testing


     Winter testing gives the opportunity to teams not only to understand the new car but also to check reliability and to improve performance as much as they can . Part of the program is also to evaluate the cooling efficiency of the car, having in mind  a wide range of possible weather conditions , for instance from cold  to very hot conditions( Bahrain , Malaysia , summer races etc ) . A significant handicap is that 2012 winter tests  took place in Spain under the cold winter time , which forces teams only to figured out which are the  most appropriate cooling options at very hot races .

    C31 at its launch version had large outlets at the back end of the sidepod tunnels , through which hot air from radiators escaped .Additionally a series of gills at both cockpit sides contributed to cool down the car internal components .

At the very first test at Jerez Sauber featured an extra outlet for the hot air located at the end of engine cover .

Jerez test and Barcelona test on February , additional outlet at engine cover’s end , gills at cockpit sides were retained

The later concept seemed to be insufficient for even hotter conditions and thus Sauber moved a step forward and tested a Red Bull style engine cover funnel in Barcelona test on March . Of course the large funnel harms overall aerodynamic efficiency of the car and it is expected as an option only for few races ( such as Bahrain , Monaco , Malaysia , Hungary , Singapore , Abu Dhabi ) where high temperatures and low average speed will be a threat to reliability .
