Fernando Alonso utilizes decades of technical experience to manage power delivery and reliability challenges. His ability to extract pace from power-deficient cars, such as his 2014 Ferrari, remains a vital component of his tactical approach to qualifying.
Mercedes engineers revolutionized Formula 1 power units by separating the compressor and turbine with a long shaft and MGU-H. This layout provided thermal and aerodynamic advantages that helped the team win 16 out of 19 races in 2014.
The 2026 Formula 1 technical regulations cause significant top speed drops at Monza, where peak race speeds fell to 351 km/h. New power unit rules mandate a 50/50 split between combustion and electrical energy, creating unpredictable closing speeds between drivers.
The 2026 power unit shift to a 50/50 power split increases thermal loads from the 350kW MGU-K. This forces teams to redesign sidepod inlets and undercuts to manage mass flow spillage and maintain diffuser pressure.
The removal of the MGU-H in 2026 forces engineers to use the 350 kW MGU-K to create artificial engine load to spool the turbocharger. This mechanism helps compensate for turbo lag, though battery capacity limits on street circuits like Monaco create significant management challenges.
Haas will maintain its Ferrari engine partnership through 2028, providing stability ahead of new power unit regulations. Meanwhile, Ayao Komatsu opposes Audi's request for special financial exemptions due to high operating costs in Switzerland.
An F1 power unit is a hybrid system of six elements. We explain each part and how they work together.
Each driver has a limited pool of engine components. Exceed it and grid drops follow. We explain the allocation and the tactics.
