Summary
- Formula 1's 2026 season brings its biggest regulation overhaul in years, with new power units that draw about half their energy from electric power and half from a 1.6-litre V6 combustion engine.
- The MGU-H is gone, the MGU-K is nearly three times more powerful (350kW), and all teams now run advanced sustainable fuels.
- The grid features five power-unit makers — Mercedes, Ferrari, Red Bull-Ford, Honda (with Aston Martin) and newcomer Audi — with Cadillac joining as a new team.
The question
