What engine modes are
Engine modes are pre-programmed settings that control how a Formula 1 power unit delivers its power. Each mode adjusts the engine's RPM limits, fuel flow rate, energy deployment, and turbo boost to optimize performance for different situations — qualifying, race starts, overtaking, and fuel saving.
Drivers select engine modes using buttons and dials on their steering wheel. A typical F1 steering wheel has over 25 buttons and 10 rotary dials, each controlling a different aspect of the car's performance.
The most common engine modes
Qualifying mode (often called "Party Mode" or "Hotlap"): This is the most aggressive setting, maximizing power output from both the internal combustion engine and the electrical system. It is used for qualifying laps and the occasional fast lap during a race.
Race mode: A balanced setting that optimizes power delivery while managing fuel consumption and energy deployment. This is the mode drivers use for most of the race.
Overtake mode: A temporary boost in electrical power deployment, used when a driver is attempting to pass another car. In 2026, this is integrated with the Active Aero system, creating a combined overtaking package.
Fuel save mode: A conservative setting that reduces fuel flow and electrical deployment to stretch the remaining fuel. Drivers use this mode when they are running low on fuel or when the team wants to conserve energy for a later push.
Why teams keep engine modes secret
Engine modes are one of the most closely guarded secrets in F1. The exact settings and the amount of power they produce are never disclosed publicly. This is because engine modes represent a significant competitive advantage — a team with a more powerful qualifying mode can gain several tenths of a second per lap in qualifying.
The FIA monitors engine modes to ensure they comply with the fuel flow and energy deployment limits, but teams are free to program their modes however they want within those constraints.
How 2026 changes engine mode management
The 2026 power unit changes make engine mode management more complex. With the internal combustion engine producing less power and the electrical component providing more, drivers must manage two energy sources simultaneously. The new Manual Override system adds another layer, giving drivers direct control over additional electrical deployment when they are within one second of the car ahead.
In 2026, the best drivers will not just be the fastest on track. They will be the ones who can manage their engine modes, energy deployment, and Active Aero configuration simultaneously — all while driving at 200 mph.
