A
B
BlisteringBlistering of the tyre caused by overheating inside the carcass, creating pockets of air that burst through the surface and rip away chunks of tread.Blue flagA signal displayed to a lapped driver informing them that a faster lead-lap car is closing behind and must be allowed through promptly.Box, boxAn urgent radio instruction from race engineer to driver ordering them to enter the pit lane on that lap for an immediate stop.
C
Chequered flagThe iconic black-and-white patterned flag waved across the finish line marking the official conclusion of a session or Grand Prix.ChicaneA tight series of alternating, quick direction-change corners introduced to slow cars down on long straights or ahead of dangerous areas.Clean airUndisturbed airflow ahead of a car with no rival immediately in front, maximizing aerodynamic cooling, grip and tyre preservation.
D
Delta timeA target lap-time reference displayed on the steering wheel dash during Virtual Safety Car periods to force drivers to maintain a safe, controlled pace.DiffuserAn expanding section at the rear underside of the car that accelerates exiting underfloor air, producing low pressure that sucks the car to the road.Dirty airTurbulent wake left behind a racing car, reducing aerodynamic downforce and overheating tyres for any car following closely.DownforceVertical aerodynamic force generated by wings and the underfloor pushing the car onto the track surface, boosting cornering grip without adding weight.DRSDrag Reduction System: a flap in the rear wing that opens in marked zones when a car is within one second of the one ahead, to help it overtake. Introduced in 2011.
E
F
Fastest lapThe quickest lap of a race. Between 2019 and 2024 it earned an extra point if the driver finished in the top ten.FloorThe large underbody surface of the chassis channeling airflow into the rear diffuser, generating the majority of total downforce via ground effect.Formation lapA slow pre-race lap where cars circulate from the grid to warm tyres and brakes before coming to a standstill in their designated starting slots.
G
GrainingTyre wear phenomenon where small rubber fragments tear off the tread and stick back onto the hot surface, creating a bumpy layer that reduces grip.Grid penaltyPlaces a driver loses on the starting grid relative to their qualifying position, for example for exceeding the engine-part allocation or for an offence in a previous session.
H
M
MarblesSmall pieces of rubber shed by tyres at speed that accumulate off the racing line, making off-line asphalt slippery and unpredictable.MGU-H (Heat)A generator linked to the turbocharger converting waste exhaust heat into electricity and spinning the turbine to eliminate turbo lag.MGU-K (Kinetic)A generator attached to the crankshaft that converts kinetic braking energy into electricity and acts as an electric motor under acceleration.
O
P
PaddockThe restricted access area located directly behind the pit lane where teams set up hospitality motorhomes, offices and operational headquarters.Parc ferméThe regime that starts with qualifying: from then on teams can barely change the car’s set-up until the race. Changing it means starting from the pit lane.Pit laneA speed-restricted access lane running parallel to the main straight (typically 80 km/h) providing entry to team garages and pit boxes.Pit stopA trip into the pit lane to change tyres (and, until 2009, refuel). A top team’s stop now lasts two to three seconds stationary.Pole positionFirst place on the starting grid, for the fastest driver in qualifying (penalties aside).PorpoisingViolent high-speed bouncing motion seen in ground-effect cars, caused by aerodynamic suction stalling and recovering repeatedly under the floor.
R
S
Safety carThe car that comes out after an incident: drivers line up behind it without overtaking until it pulls in.SidepodsSculpted bodywork housings on either flank of the cockpit holding radiators to cool the power unit while conditioning airflow towards the rear.SlipstreamReduced aerodynamic drag experienced by a car trailing closely behind another on a straight, granting extra top speed before attempting a pass.SprintA short race of about 100 km held on Saturday at some weekends since 2021, with its own qualifying and points for the top finishers.StewardsAn independent panel of adjudicators appointed by the FIA to investigate racing incidents, technical breaches and enforce rule penalties.
T
TelemetryA wireless real-time data link broadcasting hundreds of onboard vehicle parameters to the pit wall, tracking throttle, braking, tyre pressures and temperatures.Track limitsThe perimeter of the racing surface demarcated by solid white lines: placing all four wheels beyond them results in lap invalidation or time penalties.
