A
Active Aerodynamics
Active aerodynamics is a system introduced in 2026 that uses movable front and rear wing elements to automatically switch between two configurations. In Corner Mode the wings close to generate maximum downforce, and in Straight Mode the wings open to reduce drag and increase top speed on designated straights.
Apex
The apex is the innermost point of a corner on the circuit. Drivers aim to clip the apex because it allows them to carry the most speed through a turn while staying on the ideal racing line.
B
Boost Mode
Boost Mode is a driver-activated setting introduced in 2026 that deploys maximum power from both the internal combustion engine and the electric battery at the same time. Any driver can use it at any point during a lap, but the speed advantage begins to taper off above 290 km/h.
Box, Box
This is a radio message from the team telling the driver to come into the pit lane for a pit stop. The term comes from the German word for the pit lane area where the team's garage is located.
Braking Zone
The braking zone is the area on the track where a driver applies the brakes before entering a corner. It is one of the most common locations for overtaking because drivers can brake later than their rivals to gain a positional advantage.
C
Checkered Flag
The checkered flag is a black-and-white flag that is waved when the race leader crosses the finish line. It signals that the race or session has officially ended.
Clean Air
Clean air refers to the undisturbed airflow that a car receives when there is no other car running directly ahead of it. Cars running in clean air generally produce better downforce and experience less tire degradation compared to cars following closely behind others.
Constructors' Championship
The Constructors' Championship is the team-based title awarded each season. It is determined by adding together the championship points scored by both drivers on the same team across all Grand Prix and Sprint races throughout the year.
Corner Mode
Corner Mode is one of the two active aerodynamic configurations used in 2026. In this mode, the movable wing flaps are closed to generate the maximum amount of downforce, giving the car more grip through corners.
D
Delta Time
Delta time is the time difference between two laps or between two drivers on track. A positive delta means the driver is going slower than the reference time, while a negative delta means they are going faster. During Virtual Safety Car periods, drivers must follow a specific delta time displayed on their steering wheel.
Dirty Air
Dirty air is the turbulent, disrupted airflow that trails behind a moving car. When a following car drives through this turbulence, its aerodynamic surfaces become less effective, which reduces downforce and makes it harder to stay close through corners.
Downforce
Downforce is the aerodynamic force that pushes a car down onto the track surface. More downforce increases the grip available to the tires, allowing the car to corner at higher speeds. However, generating more downforce also increases drag, which reduces top speed on straights.
Drag
Drag is the air resistance that acts against a car as it moves forward. A car with less drag can achieve higher top speeds on straights, but typically has less downforce available for cornering.
DRS (Drag Reduction System)
DRS was a system used in Formula 1 from 2011 through 2025 that allowed a driver to open a flap on the rear wing to reduce drag and gain a speed boost on designated straights. It was only available when a driver was within one second of the car ahead. DRS has been replaced by Active Aerodynamics and Overtake Mode starting in 2026.
F
FIA
The FIA stands for Fédération Internationale de l'Automobile and is the international governing body of Formula 1 and many other motorsport series around the world. The FIA is responsible for creating, updating, and enforcing the technical and sporting regulations that all teams and drivers must follow.
Flat Spot
A flat spot is a worn, flattened patch on the surface of a tire that is caused by locking up the brakes. When a tire locks and stops spinning while the car is still moving, the rubber scrapes against the track in one place, creating the flat spot. This results in vibrations and reduced tire performance for the rest of the stint.
Flying Lap
A flying lap is a timed lap during qualifying or practice where the driver pushes to set the fastest possible time. It is preceded by an out lap to warm up the tires and followed by an in lap to return to the pits.
Formation Lap
The formation lap is the slow lap completed by all drivers immediately before the race starts. Drivers use this lap to warm up their tires and brakes, and then return to their assigned grid positions for the standing start.
G
Grand Prix
Grand Prix is a French term meaning "Grand Prize" and is the name given to each individual race on the Formula 1 calendar. Each Grand Prix is typically named after the country or city in which it takes place, such as the British Grand Prix or the Monaco Grand Prix.
Gravel Trap
A gravel trap is an area of loose gravel located on the outside of certain corners on a circuit. It is designed as a safety feature to slow down and stop cars that run off the track before they reach the barriers.
Grid
The grid is the starting formation where all cars line up before a race begins. Each driver's position on the grid is determined by their performance during the qualifying session held the day before the race.
M
MGU-K (Motor Generator Unit, Kinetic)
The MGU-K is a component of the hybrid power unit that converts the kinetic energy generated during braking into electrical energy, which is then stored in the battery. It can also work in reverse, deploying that stored electrical energy to boost the car's acceleration. In 2026, the MGU-K has been tripled in power output to 350 kW and now provides roughly 50% of the car's total power.
Marbles
Marbles are small pieces of rubber that shed from the tires during a race and accumulate off the main racing line. Driving over these marbles significantly reduces grip, which is why drivers try to stay on the clean, rubbered-in part of the track.
O
Out Lap
An out lap is the lap a driver completes immediately after leaving the pit lane. It is used to bring the tires and brakes up to their optimal operating temperature before beginning a timed flying lap during qualifying or a race stint.
Overtake Mode
Overtake Mode is a system introduced in 2026 that serves as the direct replacement for DRS as an overtaking aid. When a driver is within one second of the car ahead at a designated detection point, they are granted an extra 0.5 MJ of electrical energy on the following lap. The driver can choose to use this energy all at once for a single burst of speed or spread it across the entire lap for a more strategic approach.
Overcut
An overcut is a pit stop strategy where a driver deliberately stays out on track longer than a rival before making their pit stop. The goal is to take advantage of a clear track and set faster lap times while the rival deals with traffic or cold tires after their stop, ultimately gaining track position.
P
Parc Fermé
Parc fermé is a French term meaning "closed park" that refers to the strict set of rules limiting what changes teams can make to their cars after qualifying has concluded. Once a car enters parc fermé conditions, only minor adjustments are allowed before the race.
Pit Wall
The pit wall is the area along the pit lane where the team principal, race strategists, and senior engineers sit during a session. From the pit wall, the team monitors live data, communicates with the driver over the radio, and makes real-time strategic decisions.
Pole Position
Pole position is the first place on the starting grid, awarded to the driver who sets the fastest lap time during the final round of qualifying (Q3). Starting on pole is considered a significant advantage because the driver has a clear track ahead of them at the start of the race.
Podium
The podium refers to the top three finishing positions in a Grand Prix. After the race, the drivers who finish first, second, and third stand on a raised platform for the trophy ceremony, where the winner's national anthem is played.
Power Unit (PU)
The power unit is the complete engine and energy recovery package used in a modern Formula 1 car. In 2026, it consists of a 1.6-liter turbocharged V6 internal combustion engine, an MGU-K, an energy store (battery), a turbocharger, and control electronics. The MGU-H, which was used in previous seasons, has been removed from the 2026 regulations.
S
Safety Car (SC)
The Safety Car is a high-performance Mercedes-AMG road car that is deployed onto the track when a serious incident occurs during a race. All drivers must slow down and form a single-file line behind the Safety Car while marshals clear debris, recover damaged cars, or repair barriers. Overtaking is not allowed while the Safety Car is on track.
Slipstream
A slipstream is the area of reduced air resistance directly behind a moving car. A following driver can tuck into this zone on a straight to gain a speed advantage, as their car encounters less drag. This technique is often used to set up an overtaking move into the next braking zone.
Sprint
A Sprint is a shorter race of approximately 100 kilometers that takes place on Saturday at six selected weekends during the season. Championship points are awarded to the top eight finishers, and there are no mandatory pit stops required during a Sprint.
Straight Mode
Straight Mode is one of the two active aerodynamic configurations introduced in 2026. When activated in designated zones on the track, the front and rear wing flaps open simultaneously to reduce drag and increase the car's top speed. Unlike the old DRS system, Straight Mode is available to every driver on every lap regardless of the gap to the car ahead.
Sustainable Fuel
Starting in 2026, all Formula 1 cars are required to run on 100% advanced sustainable fuel. This fuel is produced from sources such as carbon capture technology, municipal waste, and non-food biomass, replacing the previous blend of fossil-based and biofuel that was used in earlier seasons.
T
Tire Compound
A tire compound refers to the specific type of rubber mixture used in the construction of a racing tire. Pirelli, the official tire supplier of Formula 1, provides five dry-weather compounds ranging from C1 (the hardest and most durable) to C5 (the softest and fastest but least durable), as well as intermediate and full wet tires for rainy conditions.
Track Limits
Track limits are the boundaries of the racing circuit, defined by the white lines painted on the edges of the track surface. Drivers must keep at least part of their car in contact with the track at all times. Repeated violations result in escalating penalties starting with a warning and progressing to time penalties.
U
Undercut
An undercut is a pit stop strategy where a driver pits earlier than a nearby rival in order to put on a fresh set of tires. The idea is that the fresh tires allow the driver to set significantly faster lap times, so that by the time the rival makes their own stop, the undercutting driver has gained enough time to emerge ahead on track.
V
Virtual Safety Car (VSC)
The Virtual Safety Car is a procedure used during races when an incident requires caution but is not serious enough to warrant the deployment of the physical Safety Car. When the VSC is activated, all drivers must reduce their speed by approximately 30% and follow a delta time displayed on their steering wheel. Unlike a full Safety Car period, the VSC mostly preserves the existing gaps between cars on track.
