Red Bull’s second significant bodywork upgrade of the season appeared at the Hungaroring and it was based around a new radiator inlet shape which rearranged the aerodynamics around the whole upper bodywork. The update was reported to be worth around 0.2s in simulation but this was the first time since Baku that a Red Bull had not sat on pole – though Verstappen missed it by only 0.003s
The new inlet is lower and wider, just as the previous one was lower and wider than the original. The sidepod panel around it is accordingly wider too. The new aspect ratio of the inlet has increased the air pressure into the radiator inlet and this has enabled an increase in cooling efficiency and more downforce creation as a result.
Through speeding up the cooling air flow (increasing the total volume of air passing over the radiators) the cooling capacity is increased as the heat in the radiators is absorbed by the passing air. If the radiator size has also been increased within that wider bodywork top, it would increase the cooling capacity further.
Although for years teams have been minimising radiator sizes and the bodywork width around them, this generation of ground effect cars has seen the evolution of that aerodynamic philosophy. It is becoming clear now that there is an aerodynamic advantage in having the upper bodywork above the undercut wider than before.
