Why F1 is eliminating the MGU-H, tripling MGU-K output, and creating the first genuine 50/50 split between combustion and electrical power — and what it means for who can compete.

A 1.6-litre, single-turbocharged V6 producing approximately 550-600bhp at up to 15,000rpm. One of the most thermally efficient combustion engines ever built — exceeding 50% thermal efficiency.

The electric motor that harvests energy under braking and deploys it as extra power. Post-2026, output triples from 120kW to 350kW — nearly matching the combustion engine for instantaneous power delivery.

A generator connected to the turbocharger shaft that harvests wasted heat energy from exhaust gases. The most technically demanding component in F1 history — and eliminated from 2026 to reduce cost and complexity.

The high-voltage battery pack at the core of the hybrid system. Stores harvested electrical energy for deployment via MGU-K, and must survive extreme temperatures, vibration, and the unique charge/discharge cycles of a Grand Prix.
