WHY ARE 2026 FORMULA 1 ENGINES GOING TO LOSE SO MUCH POWER?

EV Channels Review

The 2026 Formula 1 engine regulations signal a significant shift, primarily driven by a move from mass flow to energy flow limits for fuel. This change will drastically reduce the combustion engine's power output, from approximately 830 horsepower to 560 horsepower. Concurrently, the electric motor's power will surge from 120 kW to 350 kW, nearly tripling its contribution. Despite the combustion engine's reduction, the overall power output is expected to remain around 1,000 horsepower. Key changes include the elimination of the MGU-H, which is anticipated to reintroduce turbo lag, though its impact may be mitigated by the powerful electric motor. The MGU-K's regenerative capacity will also increase significantly. A notable constraint is the fixed battery capacity, which, combined with the more powerful electric motor, could lead to energy depletion on long straights. The video also delves into new fuel regulations, mandating sustainable fuels with higher ethanol content (E20) and stricter octane limits, alongside new intake air temperature and pressure regulations that appear to create an extremely lean air-fuel ratio, the purpose of which remains unclear to the reviewer.
