Caterham CT01 – cooling ( up to Bahrain)

       Car cooling is crucial not only for reliability but for overall efficient aerodynamic performance . Teams have to compromise between the previous two having in mind both weather conditions and the nature of track where the race takes place .

        Usually larger hot air outlets are present at high temperatures and relative slow tracks featuring many slow turns and hairpins . On the other hand tracks having long straights favor less extreme cooling configurations because the car manages to catch large volumes of fresh cooling air while crossing the stretches .

       Pre season testing is a good opportunity to test various cooling options, both conventional and  extreme which are more suitable for Malaysia and Bahrain for instance. However the pre season tests takes place during chilly European Winter time and are not representative 100% to real weather conditions the teams are about to cope with ,thus improvements are likely to be made .

      Caterham tested/raced  from car launch up to Bahrain, overall four cooling configurations as shown and analyzed below



middle sized triangular outlet at the back of the engine cover (also called funnel) , gills at exhaust zone and openings at sidepods tail .


Barcelona test on March

Huge oval outlet at the back of the engine cover, appropriate for extreme hot conditions. However it was never brought to race till now



Large circular outlet at the back of the engine cover , raced at Melbourne and Sepang


China -new concept

 Tiny triangular outlet at the back of the engine cover, double openings at sidepods tail. accompanied with diffuser revisions .Raced at Sinopec and Sakhir .This configuration leaves a cleaner airflow over the rear beam wing but as counter side it widens the coca cola bottle silhouette of the car
