The 2026 cars will be smaller, nimbler and more environmentally friendly than this year

Formula 1 has revealed the terminology the sport will use to refer to the technical complexities of the new 2026 rules.

F1 is introducing arguably the biggest regulation change in its history next season, with new chassis and engine rules, and the mandating of sustainable fuels.

The new engines, which remain 1.6-litre V6 turbo hybrids, have significantly increased electrical capacity, which has required innovations in the cars' aerodynamics.

Drivers will manage electrical energy throughout races - sometimes even on qualifying laps - to secure the best performance.
