F1 glossary: understand the language of racing

Front and rear wing angles change in permitted sections, adjusting the balance between air resistance and aerodynamic load.

The part of a cornering line nearest the inside edge. Its position influences the exit from the turn.

A command for maximum available engine and battery output, subject to energy and operating limits. It can support attacking or defending.

Performance loss as a tyre is used. Lap pace can deteriorate before the tyre appears completely worn.

Air disturbed by the leading car can weaken the following car’s aerodynamic performance and make close cornering harder.

Short for Did Not Finish. A retired driver’s classification can still depend on the distance completed.

Aerodynamic force pressing the car towards the road. It supports cornering grip, while setup choices also account for air resistance.

The previous rear-wing drag reduction system. From 2026, Active Aero and Overtake Mode perform distinct roles under the new rules.

The hybrid system recovers energy, stores it electrically and makes it available for propulsion. Battery management shapes power deployment.

The quickest lap recorded during a race. The championship’s additional fastest-lap point was removed from the 2025 season.

A time difference to another car. Check whether the timing display uses the leader or the preceding driver as its reference.

Detached rubber builds up on the tyre surface and reduces grip. The tyre can sometimes recover after this phase.

Tyres for damp or wet conditions that do not require full wets. Green sidewall markings identify them.

A wheel stops rotating under braking and slides across the road. This can create smoke and a flat area on the tyre.

An attempt to gain position by pitting after a rival. It depends on the remaining pace and conditions providing enough advantage.

The car rotates more than the steering input asks, as rear grip falls away. It is the opposite of understeer.

An electrical overtaking aid gated by a sub-second gap at the detection point. It is not simply a wing opening.

A controlled regime restricting work on the car. Some operations remain permitted under the rules, rather than every intervention being forbidden.

A stop at the team’s pit box for tyres or other work. Total time loss also includes travelling along the pit lane.

The first starting-grid position. Read qualifying results alongside any penalties when interpreting the final grid.

Recovering energy for the battery, including under braking or when lifting the throttle. Timing that recovery is part of performance management.

The safety vehicle leads the field during a neutralised period. Drivers slow down and form a queue behind it.

The circuit boundaries, normally marked by white lines. Crossing them can cause lap deletion or penalties, depending on the circumstances.

Pitting before a rival to use fresh-tyre pace and emerge ahead after the stops. A position gain is not guaranteed.

The car turns less than requested and the front tends to slide towards the outside of the corner. The opposite of oversteer.

A component or change developed to improve the car. Bringing an upgrade to a circuit does not itself prove a performance gain.

Neutralisation without a physical lead vehicle. Drivers follow reference times to reduce speed; the procedure differs from a Safety Car deployment.
