A driver must set a qualifying time within 107% of the fastest Q1 time to be allowed to start the race. If not, they must request special permission from the stewards. Ensures all cars are competitive enough to race safely.
Shown to a lapped driver to warn them a faster car is approaching to lap them. The slower driver must let the faster car pass within three flag marshal posts, or face a penalty.
When the internal temperature of the tire gets too hot, causing bubbles (blisters) to form on the surface. Results in chunks of rubber coming away, severely hurting grip and performance.
An early qualifying lap set to guarantee a safe time before making riskier attempts for a faster time. Gives the driver something 'in the bank' in case their later laps are ruined by traffic or mistakes.
The black-and-white flag waved at the finish line to signal the end of a race or session. The race leader sees it first, then every car behind crosses the line to complete the race.
The type of rubber used in a tire. F1 has five dry-weather compounds (C1 hardest to C5 softest), but each race weekend uses three, labeled Soft (red), Medium (yellow), and Hard (white). Softer tires are faster but wear out quicker.
A budget limit on how much each team can spend per season (currently $135M). Introduced in 2021 to level the playing field. Excludes driver salaries, top three executives' pay, and marketing costs.
Drag Reduction System — a movable rear wing flap that opens on straights to reduce drag and aid overtaking. Drivers can only activate DRS when within one second of the car ahead at designated detection points.
A section of track (usually a straight) where DRS can be activated. Each circuit has one to three DRS zones, each preceded by a detection point that measures the gap between cars.
Turbulent, low-energy air left behind a car. While slipstream helps on straights, dirty air hurts in corners by reducing downforce on the following car, making it harder to stay close through turns.
Did Not Finish — when a driver retires from the race before the chequered flag, due to mechanical failure, crash damage, or other issues. A DNF scores zero points.
Did Not Start — when a driver qualifies for the race but cannot take the start, usually due to a technical problem or crash on the formation lap.
Disqualified — when a driver is excluded from the results after finishing. Common causes include technical infringements (illegal car parts, underweight) or unsportsmanlike conduct.
How much slower a tire gets per lap as the rubber wears down. High degradation means lap times get progressively slower, forcing earlier pit stops. Measured in seconds-per-lap or kph-per-lap loss.
Aerodynamic force that pushes the car toward the ground, increasing grip through corners. More downforce means faster cornering but more drag on straights — teams must find the right balance for each circuit.
Air resistance that slows the car down, especially on straights. More downforce creates more drag. Low-drag setups are used at circuits like Monza (long straights), while high-downforce setups suit circuits like Monaco (tight corners).
Releasing stored electrical energy from the battery to boost the car's power. In 2026, energy management and deployment strategy is crucial — drivers must balance harvesting and deploying energy across each lap.
Energy Recovery System — harvests energy from braking (MGU-K) and exhaust heat (MGU-H, removed for 2026) and stores it in a battery. The stored energy is deployed as an electric power boost, adding roughly 120kW to the car's output.
The lap before the race starts where all cars circulate behind the pole-sitter to warm up tires and brakes. Cars must maintain grid order and return to their grid slot for the standing start.
The quickest single lap set by any driver during the race. The driver who sets it (if they finish in the top 10) earns one bonus championship point. Shown as a purple time in timing displays.
A worn patch on the tire caused by locking up under braking. Creates vibrations at high speed and reduces grip. Severe flat spots force an unplanned pit stop for fresh tires.
A timed lap where the driver pushes for the fastest possible time, as opposed to an in-lap, out-lap, or cool-down lap. In qualifying, each flying lap attempt is a chance to improve grid position.
Lap times adjusted for fuel load. Cars start heavy (~110kg of fuel) and get lighter — and faster — as fuel burns off. Correcting for this shows true pace independent of fuel weight, roughly 0.03s per lap faster as fuel burns.
When small pieces of rubber tear off the tire surface and stick back on, creating a rough, grainy texture. Causes a sudden loss of grip. Often occurs early in a stint when tires are overworked before reaching optimal temperature.
Aerodynamic downforce generated by shaping the car's floor to accelerate air underneath, creating a low-pressure area that sucks the car toward the track. The primary source of downforce in the current regulations.
A penalty that drops a driver's starting position. Common causes: exceeding the allowed number of power unit components per season, gearbox changes, or penalties carried over from a previous race.
The starting positions of all cars, arranged in a staggered two-by-two formation. Grid positions are set by qualifying results but can be modified by penalties. Also known as the starting grid.
The process of certifying that a car or component meets FIA regulations. Once homologated, certain parts cannot be changed — this is why power unit development freezes exist.
The lap on which a driver enters the pit lane for a stop. Drivers often push hard on the in-lap to build a gap before pitting, maximizing the chance of emerging ahead of rivals.
Green-marked tires designed for a damp track — not fully wet, but too wet for slicks. They have shallow treads to disperse small amounts of standing water. The most commonly used wet-weather tire.
When a driver brakes too hard and a tire stops rotating while the car is still moving, causing a flat spot on the tire. Creates a visible puff of smoke and can ruin the tire, forcing an early pit stop.
The time taken to complete one full lap of the circuit. Shown in the format M:SS.mmm (e.g. 1:28.456). Comparing lap times across stints reveals tire degradation and strategic opportunities.
Motor Generator Unit – Kinetic. Converts braking energy into electrical energy (harvesting), and also acts as a motor to boost acceleration (deployment). Connected to the rear axle.
Passing another car for position during the race. Can happen on-track through braking or speed advantage, or off-track through pit stop strategy (undercuts and overcuts).
The opposite of an undercut — staying out longer on old tires while a rival pits first. Works when the track is evolving (more rubber laid down) or the rival's out-lap on cold tires is slow, letting you gain enough time to pit and rejoin ahead.
The first lap after exiting the pit lane. Tires are cold and not yet at peak grip, so out-lap times are usually slower. A quick out-lap is crucial for making an undercut work.
Refers to how many pit stops a driver makes during a race. A one-stop strategy is usually faster overall (less time lost in pit lane) but requires managing tire degradation over longer stints.
When a car enters the pit lane to change tires (and sometimes make repairs or adjustments). A fast F1 pit stop takes under 2.5 seconds for the tire change itself, plus pit lane entry and exit time.
The range of laps during which it makes strategic sense to pit. Pitting too early wastes good tires; too late risks losing time on degraded rubber. Teams calculate optimal windows based on tire wear, track position, and rivals' strategies.
The complete engine system in an F1 car. Includes the internal combustion engine (ICE), turbocharger, and hybrid energy recovery systems (MGU-K and MGU-H). In 2026, the electrical component produces significantly more power than before.
A bouncing motion caused by ground-effect aerodynamics. At high speed, the car gets sucked down, stalls the airflow under the floor, then pops back up — repeating rapidly. Was a major issue when ground-effect cars returned in 2022.
A sealed condition applied to cars after qualifying. Once in parc fermé, teams cannot make significant changes to the car's setup before the race. Breaking parc fermé results in a pit lane start.
Points applied to a driver's FIA super license for on-track infringements (dangerous driving, causing collisions, ignoring flags). Accumulating 12 penalty points within a 12-month rolling period results in a one-race ban.
First place on the starting grid, earned by setting the fastest time in Q3. Starting from pole gives a major advantage — the driver has clean air, the shortest racing line into Turn 1, and no traffic ahead.
The fastest sector time set by any driver in the session. Shown in purple on timing screens. A lap with all three sectors in purple is the theoretical fastest possible lap.
The difference between a driver's starting grid position and their finishing position. Positive = gained places, negative = lost places. A key measure of race day performance and strategy effectiveness.
Championship points awarded for finishing positions: 25-18-15-12-10-8-6-4-2-1 for the top 10, plus 1 bonus point for fastest lap (if in the top 10). Sprint races award 8-7-6-5-4-3-2-1 for the top 8.
The session that determines the starting grid for the race. Uses a knockout format: Q1 (all drivers, bottom 5 eliminated), Q2 (15 drivers, bottom 5 eliminated), Q3 (top 10 shootout for pole position).
The three phases of qualifying. Q1: all drivers compete, slowest 5 are eliminated. Q2: remaining 15, slowest 5 eliminated. Q3: final top-10 shootout for pole. Each phase has a time limit (18/15/12 minutes).
Stops the session entirely. All cars must return to pit lane (or the grid). Used for serious incidents, extreme weather, or when the track is blocked. The race can be restarted once conditions improve.
A driver's average speed over a race stint, excluding outlier laps (pit laps, safety car periods, first lap). The best indicator of true performance — often more revealing than qualifying pace.
The low-pressure area of reduced air resistance directly behind a car. Following in the slipstream (also called tow) lets a trailing car use less engine power to maintain the same speed, building up momentum for an overtake.
A Mercedes-AMG GT that leads the field at reduced speed when track conditions are dangerous (debris, crashes, weather). No overtaking is allowed under the safety car, and the field bunches up, erasing gaps.
A continuous period of racing on one set of tires between pit stops. A typical race has 2–3 stints. Stint length depends on tire degradation, strategy, and race circumstances.
The time a car spends stationary in its pit box during a stop (tire change only). The fastest F1 pit crews achieve sub-2-second stationary times. Does not include the time spent driving through pit lane.
The configuration of a car's adjustable components — wing angles, ride height, suspension stiffness, brake balance, and more. Teams spend practice sessions finding the optimal setup for each circuit.
A shorter race (roughly 100km / ~17 laps) held on Saturday at selected Grand Prix weekends. Has its own qualifying session (Sprint Shootout) and awards points to the top 8 finishers, with the winner getting 8 points.
The officials who enforce the rules during a race weekend. They investigate incidents, hand out penalties, and rule on protests. Each event has a panel that includes an experienced ex-driver.
Each lap is divided into three sectors. Sector times show performance in each portion. Color-coded: purple = overall fastest, green = personal best, yellow = slower than personal best.
A point on the circuit where car speeds are officially measured, typically at the end of the longest straight. Speed trap data reveals power unit performance and downforce levels. Higher speed = lower drag setup.
A driver's actual position on the circuit. In F1, being ahead on track is extremely valuable because overtaking is difficult. Many strategy decisions revolve around maintaining or gaining track position.
Instructions from the team to a driver, often asking them to let their teammate pass or hold position. Used when one driver has a better championship chance, or to maximize team points.
The point where tire performance drops off dramatically rather than gradually. A driver might lose 1–2 seconds per lap suddenly. Falling off the cliff usually forces an immediate pit stop.
Electric heating wraps placed on tires before they're fitted to keep them at optimal temperature. Pre-heated tires give better grip on the out-lap. F1 is phasing these out — the 2026 regulations ban them entirely.
An official clarification or instruction from the FIA regarding how technical regulations should be interpreted. Can effectively ban certain design solutions mid-season if the FIA deems them against the spirit of the rules.
Real-time data transmitted from the car to the team's engineers. Includes hundreds of channels: speed, throttle position, brake pressure, tire temperatures, engine data, and more. Used to optimize strategy and diagnose issues.
Virtual Safety Car — a speed-limited phase where all cars must stay below a target delta time. Unlike a physical safety car, the field doesn't bunch up. Used for minor incidents where a full safety car isn't needed.
Blue-marked, fully treaded tires for heavy rain conditions. Can disperse up to 85 liters of water per second at full speed. Much slower than slicks on a dry track but essential in heavy rain.
World Drivers' Championship — the individual title awarded to the driver who accumulates the most points over a season. The most prestigious award in F1.
