Ambient temperatures can majorly impact a car’s performance. Ideally, the temperatures of individual components should be just on the limit when drivers are pushing and getting the maximum out of the car. However, achieving that is no easy task.
The unproblematic way would be to simply maximize the car’s cooling and make its ducts as big as possible. That would reduce stresses on vehicle components, but at the same time, would also have a harmful effect on aerodynamic performance, since airflow is not only used for cooling, but also to generate downforce efficiently.
“It depends on the situation you find yourself in,” says George. “Sometimes, in a perfect scenario, everything is on the limit. There’s nothing to manage and you can drive at full throttle, but when you’ve got too big a cooling effect, then quite often, you’re not optimising aerodynamic performance. You just can’t have maximum cooling for the brakes and Power Unit, because that then means you need plenty of big, fat bodywork to really cool things down, which costs performance. You have to find the right balance.”
