F1 Glossary
45+ Formula 1 terms explained in plain English — from DRS and ERS to ground effect and parc fermé.
Aerodynamics
A movable rear wing flap that reduces aerodynamic drag on straights to aid overtaking.
Aerodynamic force pushing the car down onto the track, increasing grip and cornering speed.
Aerodynamic phenomenon where the underfloor of the car generates downforce by accelerating airflow beneath it.
A bouncing phenomenon experienced by ground-effect F1 cars at high speed, caused by the floor stalling.
The rearmost section of the car's floor that expands the airflow from under the car, generating downforce.
The aerodynamic element at the front of the car that generates downforce and directs airflow.
The aerodynamic element at the rear of the car that generates downforce and includes the DRS flap.
The turbulent wake created by an F1 car that disrupts the aerodynamics of the following car.
The low-pressure wake behind a car that allows a following car to travel faster with less drag.
The flat or shaped bottom of the car that generates downforce through ground effect.
Engine
A system that recovers kinetic energy under braking and stores it for use as a power boost.
The hybrid energy recovery system in modern F1 cars, comprising MGU-K and MGU-H units.
The complete propulsion system in modern F1 cars, comprising the internal combustion engine and hybrid components.
The delay between pressing the throttle and the turbocharger delivering full boost pressure.
Racing
A road car deployed on track to neutralise the race when conditions are dangerous.
The session(s) held before a race to determine the starting grid order.
The first position on the starting grid, awarded to the fastest qualifier.
The quickest single lap set by any driver during a race, worth 1 bonus point since 2019.
A signal to stop the race immediately, typically due to a serious accident or dangerous conditions.
A system requiring all drivers to maintain a minimum lap time, used for less serious incidents.
A warning signal indicating danger ahead — drivers must slow down and not overtake.
The optimal path through a corner that minimises lap time.
A shorter race held on Saturday at selected rounds, awarding points and determining the main race grid.
Strategy
A stop in the pit lane during a race to change tyres, refuel (pre-2010), or make repairs.
A strategy where a driver pits earlier than a rival to gain track position through faster lap times on fresh tyres.
A strategy where a driver stays out longer than a rival to gain track position through clear air lap times.
Tyres
The rubber formulation of a tyre, ranging from soft (fast but fragile) to hard (durable but slower).
The rate at which a tyre loses performance over the course of a stint.
Small pieces of rubber that accumulate off the racing line, reducing grip for cars that run over them.
Regulations
A controlled area where cars are held after qualifying, preventing teams from making setup changes before the race.
A financial limit on the amount teams can spend on car development and racing operations.
A regulation requiring the underfloor of F1 cars to be flat, banning ground effect tunnels (1983-2021).
The commercial agreement between the FIA, Formula One Group, and the F1 teams governing the sport.
The governing body of Formula 1 and other motorsport disciplines worldwide.
Officials who investigate incidents during a race and issue penalties where appropriate.
See Parc Fermé.
Engineering
A computer-controlled suspension system that automatically adjusts ride height and stiffness for optimal performance.
An electronic system that prevents wheelspin by automatically reducing engine power when the driven wheels lose traction.
A structural chassis design where the outer skin bears the load, rather than an internal frame.
A lightweight, extremely strong composite material used throughout modern F1 cars.
A facility used to test aerodynamic designs by blowing air over scale models of the car.
Computer simulation of airflow around the car, used alongside wind tunnel testing for aerodynamic development.
Technical
A handling condition where the rear of the car slides outward in a corner, requiring opposite lock.
A handling condition where the front of the car pushes wide in a corner, not following the steering input.
The configuration of a car's adjustable components to optimise performance for a specific circuit.
