Meet Formula 1

This figure is an illustrative circuit (not any real track), driven anticlockwise: start/finish is at the bottom, the parallel lane below it is the pit lane, Turn 1 is on the right, the long straight is along the top, and at top left is the hairpin (a bend so tight the cars turn almost straight back).

Formula 1 is racing single-seater cars with exposed wheels around a circuit. In each race 11 teams, 22 cars in all, start together and must complete a set number of laps (about 305 km).

The first driver to finish and take the black-and-white chequered flag wins. During the race cars come into the pit lane to change tyres (a pit stop), and how quickly that goes also affects the positions.

More than twenty Grands Prix are held around the world each year, and each one adds points for drivers and teams. The next four pages look, in order, at how a race weekend runs, points, flags and penalties.

How a Sprint differs from the Grand Prix:

DistanceAbout 100 km, roughly a third of a race.

PointsOnly the top eight score, from 8 points down to 1.

Pit stopNo pit stop is required.

All Categories

Term	Abbreviation	Description	Usage & Notes
Dirty Air		Turbulent airflow coming off the car ahead that reduces downforce for the following car.	Drivers struggle to follow closely in dirty air because the front wing loses effectiveness.
Parc Fermé		Secure area and regulation period when cars are under FIA custody and only limited setup changes are allowed.	After qualifying the cars enter parc fermé, so teams must commit to their chosen setups.
Slipstream		Reduced aerodynamic drag experienced by a following car when it sits in the wake of the car ahead.	Teams sometimes sacrifice a car to give their teammate a slipstream on the long straights.
Apex		The innermost point of a corner that drivers aim to clip for the fastest racing line.	Missing the apex costs mid-corner speed and compromises the exit.
Racing Line		The fastest path through a corner or sequence that balances entry, apex, and exit speed.	Rubber from earlier sessions defines the racing line by the end of the weekend.
Track Limits		Regulation boundary defined by the painted white lines that cars must keep within while racing.	Repeatedly exceeding track limits results in warnings and time penalties.
Blue Flag		Signal shown to slower cars instructing them to let faster traffic lap without obstruction.	Ignoring blue flags can lead to a penalty for impeding.
Yellow Flag		Warning signal indicating danger ahead; drivers must slow down and be prepared to change direction.	Double yellow flags require a significant reduction in speed with no overtaking.
Safety Car SC	SC	Official car that neutralises the race and leads the field at reduced speed during major incidents.	Teams often take a free pit stop when the safety car is deployed.
Virtual Safety Car VSC	VSC	Electronic race neutralisation that enforces a minimum sector time without bunching the field behind a safety car.	Drivers must keep their delta positive during a virtual safety car period.
Understeer		Handling trait where the front tyres lose grip first, causing the car to run wide through a corner.	Drivers combat understeer by adjusting front wing angle or brake balance.
Oversteer		Handling trait where the rear tyres lose grip first, rotating the car more than intended.	Drivers prefer a hint of oversteer for qualifying rotation but tame it for race stability.
Lock-Up		Moment when a tyre stops rotating under braking, causing a skid and often creating a flat spot.	Cold brakes increase the risk of a lock-up into the first corner.
Lap		One complete trip around the circuit from the finish line back to it; race length is set as a number of laps.	He pitted with 20 laps to go.
Pit Lane		The lane beside the main straight where teams service cars in front of their garages, with a speed limit usually set at 80 km/h.	He was penalised for speeding in the pit lane.
Chequered Flag		The black-and-white flag waved at the finish line to end a session; the first car to take it wins the race.	He held on to take the chequered flag.
Red Flag		Stops the session: all cars slow down and return to the pit lane, usually after a heavy crash or dangerous weather.	The race was red-flagged after the crash at Turn 1.
Podium		The top three finishers of a race, who receive trophies on the podium after the race.	It was his first podium of the season.
Drivers' Championship		The season-long title for drivers: the top ten in each race score 25, 18, 15, 12, 10, 8, 6, 4, 2 and 1 points, and sprints pay the top eight.	He leads the championship by 12 points.
Constructors' Championship		The season-long title for teams, adding up the points of both cars; final position also decides each team’s share of prize money.	Both cars in the points kept them second in the constructors’ standings.
Out Lap		Lap immediately after leaving the pits before starting a flying lap or race stint.	Manage brake and tyre temperatures on the out lap to maximise grip for the timed lap.
Flying Lap		High-speed timed lap set after a build-up lap, used in qualifying to record the fastest possible time.	Teams coordinate tow strategies so both drivers get clean air on their flying laps.
Cool-Down Lap		Lap run at reduced speed after a push lap or race finish to cool tyres, brakes, and power unit.	Drivers pick up rubber on the cool-down lap to add weight for scrutineering if needed.
Formation Lap		Lap before the race start where the field leaves the grid, warms tyres, and re-forms on the starting positions.	Drivers perform weaving and burnouts on the formation lap to build tyre temperature.
Reconnaissance Lap		Lap or laps completed from the pit lane to the grid before the formation lap to check systems and track conditions.	Teams can complete multiple reconnaissance laps until the pit lane closes.
Free Practice 1 FP1	FP1	Opening practice session of the weekend, often used to gather baseline data and run rookie drivers.	Teams evaluate new aero packages during FP1 before committing to setups.
Free Practice 2 FP2	FP2	Second practice session, typically run in representative conditions for race simulations.	Long-run pace in FP2 gives the clearest picture of tyre behaviour.
Free Practice 3 FP3	FP3	Final practice session before qualifying, focused on short runs and setup fine-tuning.	FP3 is the final chance to test qualifying trim before parc fermé.
Qualifying		Timed session that determines the starting grid through a three-phase knockout format.	Qualifying pace often highlights which teams extract the most from new tyres.
Q1 Q1	Q1	Opening segment of qualifying where the slowest five cars are eliminated.	Traffic management in Q1 is crucial on tight street circuits.
Q2 Q2	Q2	Middle segment of qualifying that decides the top ten shootout and eliminates five more drivers.	Drivers may run two sets of tyres in Q2 to ensure progression.
Q3 Q3	Q3	Final qualifying shootout where the remaining ten cars fight for pole position.	A slipstream can decide pole in Q3 on high-speed circuits.
Sprint		Short race held on selected weekends that awards points and sets a separate result from the Grand Prix.	Teams balance risk in the sprint to avoid compromising the main race.
Sprint Qualifying		Short qualifying session held on sprint weekends to set the sprint starting order.	Under the 2026 rules, dry SQ1 and SQ2 use medium-specification tyres while SQ3 uses soft-specification tyres.
Grand Prix		One round of the championship: a race weekend at one circuit, ending with the Sunday race of about 305 km (Monaco is shorter).	The 2027 season has 24 Grands Prix.
Starting Grid		The painted slots behind the start line where cars line up in two staggered rows, in the order set by qualifying.	He starts from the third row of the grid.
Pole Position		First place on the starting grid, earned by the fastest lap in the final part of qualifying (Q3).	She took pole by a tenth of a second.
Lights Out		The standing start: five red lights come on one by one and the race begins the moment they all go out.	It’s lights out and away we go!
Undercut		Strategy where a driver pits earlier to use fresh tyres and gain time over a rival who stays out.	The undercut is powerful when tyre degradation is high and out-lap grip matters.
Overcut		Strategy of staying on track longer to benefit from clear air or tyre offset once rivals have pitted.	The overcut works when the leading driver has strong tyre life and open track ahead.
Box, Box		Radio instruction telling the driver to enter the pit lane at the end of the current lap.	Engineers repeat "box, box" to confirm the driver acknowledges the pit stop call.
Delta Time		Minimum lap time reference a driver must adhere to during Safety Car or Virtual Safety Car conditions.	Drivers monitor the steering wheel display to keep the delta in the green zone.
Pit Window		Planned lap range during which a team intends to pit based on tyre life, fuel load, and traffic.	A sudden safety car can close the pit window earlier than planned.
Offset Strategy		Plan to run a different tyre compound sequence from rivals to create pace or life advantages at alternate phases.	Teams will split cars onto offset strategies to cover multiple scenarios.
Split Strategy		Approach where a team runs its two cars on different race plans to hedge against uncertainty.	A split strategy lets one car gamble on a late safety car while the other plays safe.
One-Stop		Race plan involving a single pit stop, relying on tyre management to stretch each stint.	A one-stop can succeed on circuits with low degradation and long pit lanes.
Two-Stop		Race approach using two pit stops to keep tyres in a faster temperature and wear window.	High-degradation tracks like Barcelona often reward a committed two-stop.
Safety Car Pit Stop		Pit stop taken while the safety car is deployed, costing less time relative to rivals who stay out.	Teams save a set of tyres in case a late safety car creates a free stop.
Alternate Tyre Strategy		Using the mandatory second compound early to unlock strategic flexibility later in the race.	An alternate tyre strategy can help avoid getting stuck behind slower cars.
Pit Stop		Stopping in the pit box during a race so the crew can change tyres, usually in under three seconds; in a dry race each driver must use two different dry compounds.	A slow pit stop cost him two places.
C-Compound C1–C5	C1–C5	Pirelli designations for the five dry tyre constructions, from hardest C1 to softest C5.	FIA selects three C-compounds each weekend to become the hard, medium, and soft race tyres.
Hard Tyre H	H	White-marked slick tyre that is the most durable option but offers the least peak grip.	Teams rely on the hard tyre for long defensive stints in hot conditions.
Medium Tyre M	M	Yellow-marked slick that balances endurance with performance and is often the default race tyre.	Safety car restarts frequently see the field on medium tyres.
Soft Tyre S	S	Red-marked slick that offers the highest grip but degrades faster than the harder options.	Soft tyres are ideal for qualifying or late-race attacks.
Slick Tyres		Tyres without grooves designed for dry conditions to maximise the contact patch and grip.	Drivers switch back to slicks once a damp track has dried enough for a racing line.
Graining		Surface wear pattern where rubber rolls into small pellets, reducing grip until the tyre cleans up.	Cold track temperatures or sliding in corners often trigger graining on the front tyres.
Blistering		Damage where the tyre surface overheats and bubbles, tearing away chunks of rubber.	Excess camber or aggressive setups can cause blistering on hot days.
Flat Spot		Patch worn flat on a tyre after a lock-up, creating vibration and reducing performance.	Severe flat spots can force an extra pit stop to change tyres.
Marbles		Bits of rubber torn from tyres that accumulate off the racing line and reduce grip if collected.	Drivers avoid overtaking off-line late in the race because marbles make the surface slippery.
Heat Cycle		Process of bringing a tyre up to temperature and letting it cool, which can change its characteristics for later use.	Scrubbed tyres have already been through a heat cycle to stabilise pressure.
Scrubbed Tyres		Tyres that have been lightly used to remove the release agent and stabilise pressures before serious running.	Teams often scrub tyres in practice so they are ready for the race start.
Tyre Blankets		Electric heating covers that pre-warm tyres to the mandated temperature before fitting on the car.	Teams manage blanket timing carefully to keep tyres in the working range without overheating.
MGU-K MGU-K	MGU-K	Motor generator unit - kinetic; harvests energy under braking and deploys electric power to the drivetrain.	Teams fine-tune MGU-K deployment maps to balance lap time and energy saving.
MGU-H MGU-H	MGU-H	Former motor generator unit - heat used in the 2014-2025 hybrid era; it recovered exhaust energy from the turbocharger and controlled turbo speed.	MGU-H still appears in older power-unit explanations, but the current 2026 PU element list no longer includes it.
ERS ERS	ERS	Collective term for the hybrid components that harvest and deploy electrical energy on an F1 car.	Drivers switch ERS modes to defend on straights or recharge during calmer laps.
Energy Store ES	ES	High-voltage battery pack that stores harvested electrical energy for later deployment.	Energy store temperature management is critical on hot street circuits.
Internal Combustion Engine ICE	ICE	Six-cylinder 1.6-litre turbocharged engine that forms the combustion core of the power unit.	Teams monitor ICE mileage to schedule component changes before reliability drops.
Turbocharger TC	TC	Device driven by exhaust gases that compresses intake air to increase engine power.	Turbocharger temperatures are carefully managed to avoid power fade late in stints.
Control Electronics CE	CE	Standardised electronic hardware that manages the hybrid systems, engine settings, and data logging.	Any issue with the control electronics can force a retirement despite a healthy engine.
Brake-By-Wire BBW	BBW	Electronic control system that manages rear brake pressure and energy recovery balance instead of a direct hydraulic link.	Drivers tune brake-by-wire maps to keep pedal feel consistent as the hybrid system harvests energy.
Front Wing		Primary aerodynamic structure at the nose that generates downforce and directs airflow around the car.	Adjusting front wing flap angle is a quick way to change balance between sessions.
Rear Wing		Large aerodynamic wing mounted above the gearbox that provides the majority of rear downforce.	Teams swap rear wing levels to suit tracks with different straight-line demands.
Beam Wing		Secondary rear wing element mounted low between the endplates to seal the diffuser and add stability.	Teams trim the beam wing to cut drag on circuits with many straights.
Diffuser		Upswept section of the floor that accelerates airflow to create low pressure and rear downforce.	Damage to the diffuser can dramatically cut grip even if the wings remain intact.
Floor		Large aerodynamic surface under the car that generates ground-effect downforce through venturi tunnels.	Teams run ride-height sensors to prevent the floor from stalling over bumps.
Sidepod		Bodywork on either side of the cockpit housing radiators, cooling ducting, and aerodynamic surfaces.	Different sidepod shapes influence cooling efficiency and airflow to the rear.
Halo		Titanium structure surrounding the cockpit opening that deflects debris and protects the driver's head.	Several major crashes have proven the halo's lifesaving capability.
Survival Cell		Central carbon-fibre monocoque that houses the driver and fuel tank, designed to withstand extreme impacts.	The survival cell is tested with rigorous static and dynamic crash procedures each season.
Pushrod Suspension		Suspension design where a rod connected to the wheel hub pushes inboard springs and dampers mounted high in the chassis.	Many teams use pushrod front suspension to simplify packaging of steering components.
Pullrod Suspension		Suspension layout where the rod pulls downward on inboard elements mounted low in the chassis for a lower centre of gravity.	Several teams favour pullrod rear suspension to streamline airflow over the diffuser.
Brake Duct		Aerodynamic intake around the wheel that channels air to cool the brakes and condition airflow to the tyres.	Teams swap brake duct sizes depending on expected temperatures and stopping demands.
Overtake Mode		From 2026 a driver within one second of the car ahead at the detection point gets extra electrical energy to attack on the next lap; it replaces DRS, which was used until 2025.	He used overtake mode to pass on the back straight.
Boost Mode		A driver-pressed button that releases the maximum power of engine and battery at any point on the lap, used to attack or defend while energy lasts.	He saved his boost to defend into the last corner.
Active Aero		From 2026 the front and rear wings move: Straight Mode flattens them on marked straights to cut drag, and Corner Mode restores downforce for the bends.	Every driver can use Straight Mode on the main straight, not just the one following.
Purple Sector		Sector time coloured purple on timing screens to indicate the fastest split of the entire field.	Commentary will note when a driver goes purple in sector two during a qualifying run.
Green Sector		Timing colour indicating a driver's personal-best sector that is not the overall fastest.	Seeing a string of green sectors shows a driver is building pace lap by lap.
Yellow Sector		Timing colour that shows a sector slower than the driver's best, often due to traffic or mistakes.	Engineers investigate yellow sectors to pinpoint where pace was lost.
Lift and Coast		Technique where the driver releases the throttle earlier and coasts before braking to save fuel or manage temperatures.	Engineers call for lift and coast to avoid critical brake temperatures on street circuits.
Brake Magic		Mercedes term for an extreme brake bias and energy harvest mode used to warm front brakes and tyres on formation laps.	Accidentally leaving brake magic enabled on a restart can cause massive front brake lock-ups.
Telemetry Stream		Continuous transmission of sensor data from the car to the pit wall for monitoring in real time.	Teams flag anomalies in the telemetry stream to prevent failures before they occur.
Throttle Trace		Graph showing throttle pedal position over time, used to analyse driving style and car response.	Comparing throttle traces between teammates highlights who is earlier on power.
Brake Trace		Plot of brake pressure applied through a lap to study modulation, trail braking, and balance.	Brake traces help identify confidence issues when a driver lifts early into heavy braking zones.
Strat Mode		Preset engine and hybrid deployment maps selected from the steering wheel to adjust power output and efficiency.	Drivers switch strat modes between attack laps and energy-saving phases.
Drive-Through Penalty		Penalty requiring the driver to enter pit lane without stopping, losing significant time relative to rivals.	A drive-through is typically issued for jump starts or repeated track limits violations.
Stop-Go Penalty		Penalty where the driver stops at their pit box for a timed hold before rejoining the race.	A 10-second stop-go is one of the harshest in-race penalties short of disqualification.
Grid Penalty		Pre-race sanction that moves a driver back a set number of grid places, often for power unit component usage.	Teams may take a full power unit change and start from the back when multiple grid penalties accumulate.
Time Penalty		Fixed number of seconds added to a driver's race time or served at the next pit stop.	Five-second penalties are common for track limits or unsafe releases.
Reprimand		Formal warning issued by the stewards that can contribute to further penalties if accumulated.	Three reprimands in a season, with at least two driving offences, trigger a ten-place grid drop.
Penalty Points		Points added to a driver's FIA Super Licence for incidents; reaching twelve within twelve months triggers a race ban.	Drivers monitor penalty points closely to avoid missing a Grand Prix.
Black and White Flag		Flag shown as a final warning for unsportsmanlike behaviour before further penalties are applied.	The stewards may wave the black and white flag for repeated weaving or track limits abuse.
Black Flag		Signal that disqualifies a driver from the race and orders immediate return to the pits.	Ignoring a black flag can lead to further disciplinary action from the FIA.
Track Evolution		Progressive build-up of rubber and temperature on the racing line that increases grip over a session or weekend.	Teams plan qualifying runs late to exploit peak track evolution and faster lap times.
Intermediate Tyres INT	INT	Green-marked wet-weather tyre designed for light rain and drying conditions with shallow grooves.	Intermediates overheat quickly on a fully dry track, forcing drivers to pit for slicks.
Full Wet Tyres WET	WET	Blue-marked wet tyre with deep grooves that can disperse large amounts of standing water.	Full wets are reserved for heavy standing water and reduced visibility conditions.
Crossover Point		Moment when a drying track becomes quicker on slick tyres than on intermediates or wets.	Teams watch sector deltas to judge the crossover point for slick tyres.
Aquaplaning		Loss of contact between tyre and track when a layer of water lifts the car, causing loss of control.	Drivers radio aquaplaning when full wets can no longer clear the standing water.
Damp Patch		Lingering wet area on the circuit that dries slower than the racing line and can catch drivers out.	Qualifying laps on slicks can be ruined by a single damp patch off-line.
Track Temperature		Temperature of the asphalt surface, crucial for tyre performance and degradation.	Teams monitor track temperature to choose starting tyre pressures.
Ambient Temperature		Temperature of the surrounding air, affecting engine cooling and tyre warm-up.	Cool ambient conditions make it harder to keep tyres in their operating window.
Wind Direction		Orientation of the wind across the circuit, influencing braking points and cornering balance.	A sudden headwind can allow drivers to brake later into turn one.

About F1 Racing Terminology Reference Table

Car systems, sessions, tyres, and race language

The table organizes F1 terms across car systems, sessions, strategy, tyre compounds, telemetry, penalties, weather, and track conditions. It is designed for decoding broadcasts, articles, race-weekend notes, and sim-racing discussions without turning the page into live timing.

Filter technical terms by race context

Search matches localized terms, English labels, abbreviations, aliases, and keywords. Category filters separate sessions, tyres, car systems, telemetry, penalties, weather, and strategy so a radio call or race analysis can be narrowed quickly.

Not live timing or race engineering advice

FIA regulations, sprint-session wording, technical rules, and sporting procedures can change by season. Use this as a glossary, then confirm FIA documents, official race control notices, team material, or simulator setup guides when a decision affects rules, safety, competition, or equipment.

FAQ

Common questions and answers about this topic.

How do I find common F1 abbreviations and team radio calls?

Search a localized term, English label, abbreviation, alias, or keyword. You can also filter the 95 entries by sessions, tyres, strategy, car systems, telemetry and radio, penalties, weather, or general concepts.

What is the difference between an undercut and an overcut in F1?

An undercut means pitting earlier to use fresh tyres and gain time on a rival who stays out. An overcut means staying out longer to use clear track or a tyre-life advantage after the rival pits. Tyre degradation, traffic, and open track affect which strategy works.

What is the difference between the Safety Car and Virtual Safety Car?

The Safety Car is a physical official car that leads the field at reduced speed and gathers the cars together. The Virtual Safety Car electronically imposes a minimum sector-time delta without forming the field behind a physical car.

Do F1 terms change when the regulations change?

Yes. Session names, technical terms, and procedures can change by season. This table is checked against the 2026 FIA regulations, marks MGU-H as a 2014-2025 legacy term, and keeps Sprint Shootout as an alias for the current Sprint Qualifying label. Confirm current FIA documents when a decision depends on the rules.

Scrubbed Tyres		Tyres that have been lightly used to remove the release agent and stabilise pressures before serious running.	Teams often scrub tyres in practice so they are ready for the race start.
Tyre Blankets		Electric heating covers that pre-warm tyres to the mandated temperature before fitting on the car.	Teams manage blanket timing carefully to keep tyres in the working range without overheating.
MGU-K MGU-K	MGU-K	Motor generator unit - kinetic; harvests energy under braking and deploys electric power to the drivetrain.	Teams fine-tune MGU-K deployment maps to balance lap time and energy saving.
MGU-H MGU-H	MGU-H	Former motor generator unit - heat used in the 2014-2025 hybrid era; it recovered exhaust energy from the turbocharger and controlled turbo speed.	MGU-H still appears in older power-unit explanations, but the current 2026 PU element list no longer includes it.
ERS ERS	ERS	Collective term for the hybrid components that harvest and deploy electrical energy on an F1 car.	Drivers switch ERS modes to defend on straights or recharge during calmer laps.
Energy Store ES	ES	High-voltage battery pack that stores harvested electrical energy for later deployment.	Energy store temperature management is critical on hot street circuits.
Internal Combustion Engine ICE	ICE	Six-cylinder 1.6-litre turbocharged engine that forms the combustion core of the power unit.	Teams monitor ICE mileage to schedule component changes before reliability drops.
Turbocharger TC	TC	Device driven by exhaust gases that compresses intake air to increase engine power.	Turbocharger temperatures are carefully managed to avoid power fade late in stints.
Control Electronics CE	CE	Standardised electronic hardware that manages the hybrid systems, engine settings, and data logging.	Any issue with the control electronics can force a retirement despite a healthy engine.
Brake-By-Wire BBW	BBW	Electronic control system that manages rear brake pressure and energy recovery balance instead of a direct hydraulic link.	Drivers tune brake-by-wire maps to keep pedal feel consistent as the hybrid system harvests energy.
Front Wing		Primary aerodynamic structure at the nose that generates downforce and directs airflow around the car.	Adjusting front wing flap angle is a quick way to change balance between sessions.
Rear Wing		Large aerodynamic wing mounted above the gearbox that provides the majority of rear downforce.	Teams swap rear wing levels to suit tracks with different straight-line demands.
Beam Wing		Secondary rear wing element mounted low between the endplates to seal the diffuser and add stability.	Teams trim the beam wing to cut drag on circuits with many straights.
Diffuser		Upswept section of the floor that accelerates airflow to create low pressure and rear downforce.	Damage to the diffuser can dramatically cut grip even if the wings remain intact.
Floor		Large aerodynamic surface under the car that generates ground-effect downforce through venturi tunnels.	Teams run ride-height sensors to prevent the floor from stalling over bumps.
Sidepod		Bodywork on either side of the cockpit housing radiators, cooling ducting, and aerodynamic surfaces.	Different sidepod shapes influence cooling efficiency and airflow to the rear.
Halo		Titanium structure surrounding the cockpit opening that deflects debris and protects the driver's head.	Several major crashes have proven the halo's lifesaving capability.
Survival Cell		Central carbon-fibre monocoque that houses the driver and fuel tank, designed to withstand extreme impacts.	The survival cell is tested with rigorous static and dynamic crash procedures each season.
Pushrod Suspension		Suspension design where a rod connected to the wheel hub pushes inboard springs and dampers mounted high in the chassis.	Many teams use pushrod front suspension to simplify packaging of steering components.
Pullrod Suspension		Suspension layout where the rod pulls downward on inboard elements mounted low in the chassis for a lower centre of gravity.	Several teams favour pullrod rear suspension to streamline airflow over the diffuser.
Brake Duct		Aerodynamic intake around the wheel that channels air to cool the brakes and condition airflow to the tyres.	Teams swap brake duct sizes depending on expected temperatures and stopping demands.
Overtake Mode		From 2026 a driver within one second of the car ahead at the detection point gets extra electrical energy to attack on the next lap; it replaces DRS, which was used until 2025.	He used overtake mode to pass on the back straight.
Boost Mode		A driver-pressed button that releases the maximum power of engine and battery at any point on the lap, used to attack or defend while energy lasts.	He saved his boost to defend into the last corner.
Active Aero		From 2026 the front and rear wings move: Straight Mode flattens them on marked straights to cut drag, and Corner Mode restores downforce for the bends.	Every driver can use Straight Mode on the main straight, not just the one following.
Purple Sector		Sector time coloured purple on timing screens to indicate the fastest split of the entire field.	Commentary will note when a driver goes purple in sector two during a qualifying run.
Green Sector		Timing colour indicating a driver's personal-best sector that is not the overall fastest.	Seeing a string of green sectors shows a driver is building pace lap by lap.
Yellow Sector		Timing colour that shows a sector slower than the driver's best, often due to traffic or mistakes.	Engineers investigate yellow sectors to pinpoint where pace was lost.
Lift and Coast		Technique where the driver releases the throttle earlier and coasts before braking to save fuel or manage temperatures.	Engineers call for lift and coast to avoid critical brake temperatures on street circuits.
Brake Magic		Mercedes term for an extreme brake bias and energy harvest mode used to warm front brakes and tyres on formation laps.	Accidentally leaving brake magic enabled on a restart can cause massive front brake lock-ups.
Telemetry Stream		Continuous transmission of sensor data from the car to the pit wall for monitoring in real time.	Teams flag anomalies in the telemetry stream to prevent failures before they occur.
Throttle Trace		Graph showing throttle pedal position over time, used to analyse driving style and car response.	Comparing throttle traces between teammates highlights who is earlier on power.
Brake Trace		Plot of brake pressure applied through a lap to study modulation, trail braking, and balance.	Brake traces help identify confidence issues when a driver lifts early into heavy braking zones.
Strat Mode		Preset engine and hybrid deployment maps selected from the steering wheel to adjust power output and efficiency.	Drivers switch strat modes between attack laps and energy-saving phases.
Drive-Through Penalty		Penalty requiring the driver to enter pit lane without stopping, losing significant time relative to rivals.	A drive-through is typically issued for jump starts or repeated track limits violations.
Stop-Go Penalty		Penalty where the driver stops at their pit box for a timed hold before rejoining the race.	A 10-second stop-go is one of the harshest in-race penalties short of disqualification.
Grid Penalty		Pre-race sanction that moves a driver back a set number of grid places, often for power unit component usage.	Teams may take a full power unit change and start from the back when multiple grid penalties accumulate.
Time Penalty		Fixed number of seconds added to a driver's race time or served at the next pit stop.	Five-second penalties are common for track limits or unsafe releases.
Reprimand		Formal warning issued by the stewards that can contribute to further penalties if accumulated.	Three reprimands in a season, with at least two driving offences, trigger a ten-place grid drop.
Penalty Points		Points added to a driver's FIA Super Licence for incidents; reaching twelve within twelve months triggers a race ban.	Drivers monitor penalty points closely to avoid missing a Grand Prix.
Black and White Flag		Flag shown as a final warning for unsportsmanlike behaviour before further penalties are applied.	The stewards may wave the black and white flag for repeated weaving or track limits abuse.
Black Flag		Signal that disqualifies a driver from the race and orders immediate return to the pits.	Ignoring a black flag can lead to further disciplinary action from the FIA.
Track Evolution		Progressive build-up of rubber and temperature on the racing line that increases grip over a session or weekend.	Teams plan qualifying runs late to exploit peak track evolution and faster lap times.
Intermediate Tyres INT	INT	Green-marked wet-weather tyre designed for light rain and drying conditions with shallow grooves.	Intermediates overheat quickly on a fully dry track, forcing drivers to pit for slicks.
Full Wet Tyres WET	WET	Blue-marked wet tyre with deep grooves that can disperse large amounts of standing water.	Full wets are reserved for heavy standing water and reduced visibility conditions.
Crossover Point		Moment when a drying track becomes quicker on slick tyres than on intermediates or wets.	Teams watch sector deltas to judge the crossover point for slick tyres.
Aquaplaning		Loss of contact between tyre and track when a layer of water lifts the car, causing loss of control.	Drivers radio aquaplaning when full wets can no longer clear the standing water.
Damp Patch		Lingering wet area on the circuit that dries slower than the racing line and can catch drivers out.	Qualifying laps on slicks can be ruined by a single damp patch off-line.
Track Temperature		Temperature of the asphalt surface, crucial for tyre performance and degradation.	Teams monitor track temperature to choose starting tyre pressures.
Ambient Temperature		Temperature of the surrounding air, affecting engine cooling and tyre warm-up.	Cool ambient conditions make it harder to keep tyres in their operating window.
Wind Direction		Orientation of the wind across the circuit, influencing braking points and cornering balance.	A sudden headwind can allow drivers to brake later into turn one.
