McLaren has highlighted how an all-new engine cooling system for its 2025 Formula 1 car is playing an important part in its hot weather advantage
McLaren has introduced a new engine cooling system for its 2025 Formula 1 car, providing a competitive advantage in hot weather conditions, alongside rear tyre temperature management.
Efficiency in cooling the Mercedes power units allows McLaren to optimize its bodywork configuration for enhanced aerodynamics, reducing drag and minimizing disruptions to the rear wing and diffuser.
This enables McLaren to potentially achieve better lap times and tire wear by adjusting the level of downforce based on the reduced drag from the efficient cooling system.
The unique cooling setup of McLaren has been particularly noted at the Monaco Grand Prix, where maintaining appropriate engine temperatures becomes crucial due to the circuit layout.
Team principal Andrea Stella emphasized the complete overhaul of McLaren’s cooling design, attributing their impressive performance in hot conditions to the increased efficiency of the new system.
Considering the challenges of running closely behind other cars, McLaren must carefully balance their cooling levels to ensure optimal performance and adaptability on race day.
