Learn Formula 1
F1 explained for the 2026 era.
Start with the answer, then understand the system. Every regulation-sensitive guide is written for active aero, electrical deployment and the current sporting rules.
2026 terminology: Corner Mode and Straight Mode are the current public names. Early FIA material called them Z-Mode and X-Mode; DRS is no longer the active system.

2026 rules
Active aerodynamics
Movable front and rear wing elements now switch between cornering and low-drag configurations.
Corner Mode
The high-downforce active-aero configuration used away from designated straight-line sections.
Straight Mode
The low-drag active-aero configuration available in approved high-speed sections.
Overtake Mode
The 2026 close-following aid that gives an eligible chasing driver extra electrical deployment.
Boost Mode
The driver-operated maximum-deployment tool that is distinct from Overtake Mode.
Recharge

2026 power units
A simpler turbo-hybrid formula with much more electrical power and no MGU-H.
Sustainable fuel
The drop-in fuel requirement introduced with Formula 1's new power-unit generation.
Why DRS is gone
DRS ended because the new cars need active wings for energy efficiency, with Overtake Mode handling close-racing assistance.
