Formula 1 is the world championship for single-seaters: around two dozen Grands Prix a year, on permanent and street circuits across five continents. Every race awards points, and at the end of the season two champions are crowned: the driver with the most points and the team with the most points.
It is not a knockout cup: consistency is what counts. A title can be won without winning the final race, and lost despite winning more Grands Prix than anyone else.
The FIA (the international automobile federation) writes the technical and sporting rules and sends the race director and the stewards to every event. Formula One Group, which holds the commercial rights, sets the calendar, sells the TV rights and runs the show. The teams design and build their own cars: that is what makes F1 a constructors’ championship, not only a drivers’ one.
The “formula” is the set of rules every car must meet: dimensions, minimum weight, engine type, fuel and energy limits. Every few years the formula changes deeply: 2026 is one of those years, with entirely new engines and aerodynamics.
Six weekends a year add an extra race, the sprint: about 100 km, no mandatory stop, on Saturday. It has its own qualifying (Sprint Qualifying) and pays points to the top eight, from 8 down to 1. Sunday’s grid is still set by the normal qualifying.
Chassis, power unit, aerodynamics and tyres: what is inside a 2026 Formula 1 car.
The heart of the car is the carbon-fibre monocoque: an extremely stiff cell that protects the driver and carries the engine, suspension and bodywork. Above the driver’s head sits the halo, a titanium hoop that can hold the weight of a bus and has already saved more than one driver. From 2026 the cars are shorter, narrower and around 30 kg lighter than the year before.
It is not called an engine but a power unit: a 1.6-litre turbo V6 paired with an electric motor (MGU-K) that recovers energy under braking and gives it back on acceleration, plus a battery and a control unit. From 2026 the electric side delivers almost half of the total power, the MGU-H (which recovered energy from the turbo) is gone and the fuel is fully sustainable.
Each driver may use only a limited number of power unit elements in a season: fitting one more means starting further back on the grid. We count them for every driver on the Power unit page.
The gearbox has eight gears, shifted with paddles behind the steering wheel: a gear change takes a few thousandths of a second. The brakes are carbon discs that run above 1000 °C; at the rear, part of the braking is done by the electric motor while it charges the battery. The suspension keeps the car at the right ride height, which matters as much as the engine for the aerodynamics.
Wings and floor push the car down (downforce) so it can corner faster. From 2026 both the front and the rear wing move: on the straights they open to cut drag, in the corners they close to add downforce. The old DRS is gone: to overtake, a car within one second of the one ahead can use extra electrical energy.
At every weekend Pirelli brings three dry compounds chosen from six (from C1, the hardest, to C6, the softest): hard with white markings, medium yellow, soft red. For the rain there are intermediates (green) and full wets (blue). In a dry race every driver must use at least two different compounds: that is why there is at least one pit stop.
How a team is built, why the cars are not the same and what numbers and codes mean.
Behind two cars on track work more than a thousand people: designers, aerodynamicists, race engineers, mechanics, strategists, logistics staff. On the pit wall sit the team principal, the race engineers (who talk to the drivers on the radio) and the strategists; back at the factory more engineers follow the session in real time.
In 2026 there are eleven teams, with Cadillac’s arrival and Audi’s debut: 22 cars on the grid. You will find them all, with cars and liveries, under Constructors.
Every team builds its own car within the same rules, so performance varies a lot. To stop the biggest spender from always winning there is an annual cost cap, and the teams lower down get more wind-tunnel time than those at the front. Some teams buy their power unit from a manufacturer (they are called “customers”).
The fairest comparison is between teammates, who drive the same car: that is what we show in Head to head.
Each driver picks a race number to keep for their whole career; the reigning champion may use number 1. On TV and on the timing screens drivers are shown by three letters (ANT, VER, LEC…). The radio between driver and pit wall is open: the FIA and TV can listen, which is why coded messages are sometimes heard.
Telemetry, timing and who judges what happens on track.
An F1 car carries hundreds of sensors: speed, revs, gear, throttle, brake, temperatures, tyre pressures, track position. The data reaches the garage and the factory in real time, but only one way: engineers cannot change the car’s settings remotely, they can only ask the driver to do it.
Part of this data is public: with our Telemetry you can overlay two drivers’ laps and see where one brakes earlier or exits a corner faster.
Every lap is split into three sectors and dozens of mini-sectors, timed to the thousandth. The colours are always the same: purple for the session’s best, green for a personal best, yellow for a slower time. It is the language of our Live Timing.
The race director runs the session: flags, safety car, stoppages. Infringements are judged by the stewards, a panel of three plus a former driver, who review footage and data and decide penalties. Every decision is a public document: we collect them on the FIA documents page.
From practice to the starting grid, session by session.
A normal weekend has three practice sessions (one hour each), qualifying on Saturday and the race on Sunday. Sprint weekends have a single practice session, then Sprint Qualifying and the sprint, plus qualifying for the race. The times in your time zone are in the Calendar.
They are for finding the set-up, trying the tyres and preparing the race: so the times must be read with care. One driver may run heavy on fuel to simulate the race, another light for qualifying. The pace over long runs often says more than the best lap.
Qualifying is a knockout. In Q1 (18 minutes) everyone runs and the slowest six are out; in Q2 (15 minutes) six more go; in Q3 (12 minutes) the remaining ten fight for pole position. A driver slower than 107% of the best Q1 time risks not being allowed to race.
The grid does not always match the qualifying order: penalties for power unit changes, infringements or changes to the car move drivers back, and anyone who modifies the car under parc fermé starts from the pit lane. The “From qualifying to the race” chart in Results shows these moves.
Start, pit stops, safety car and flags: what happens between the start and the chequered flag.
After a formation lap the cars stop in their grid slots. Five red lights come on, one per second; when they all go out, the race is on. Moving early is a jump start and costs a penalty. A race covers at least 305 km (Monaco is the exception) and lasts at most two hours of racing.
Around twenty mechanics change all four tyres in just over two seconds. The time that really counts, though, is the time lost through the whole pit lane, usually 18 to 25 seconds depending on the track. There is a speed limit in the pit lane, and an unsafe release costs a penalty. The season’s fastest stops are on Pit stops.
If there is danger on track the safety car comes out: the cars line up behind it without overtaking and the gaps disappear. The virtual safety car (VSC) instead forces everyone to a minimum time per sector, without a queue. Under a red flag the race stops and the cars return to the pits; it can restart, even from a standing start.
A stop made under safety car or VSC costs less time: that is why the pit lane fills up as soon as it comes out.
Green: track clear. Yellow: danger, slow down and no overtaking (double yellow: be ready to stop). Red: session stopped. Blue: you are about to be lapped, let them through. White: slow vehicle on track. Black and white split diagonally: warning for unsporting behaviour. Black with an orange circle: mechanical problem, return to the pits. Black: disqualification. Yellow and red stripes: slippery surface. Chequered: end of the session.
After the chequered flag the cars go to parc fermé, where the FIA weighs and checks them. A technical irregularity, such as being underweight or an over-worn floor, leads to disqualification even hours after the race. The result is only final once the checks are done.
When to stop, which tyres to fit and how to overtake without overtaking.
Every tyre loses performance lap after lap. The “window” is the group of laps in which stopping pays off: too early and the new tyre will not last to the end, too late and time is lost on a worn tyre. Every driver’s lap-by-lap pace, with their tyres, is in Race pace.
Undercut: stop before your rival and use the fresher, faster tyre to be ahead when they stop too. Overcut: the opposite, stay out longer because the old tyre is still good or the track ahead is clear. Which one works depends on how fast the tyres wear on that track and how much a stop costs.
Teammates are rivals for the drivers’ title but allies for the constructors’ one. Sometimes the pit wall asks one to let the other through, or to hold up a rival: it is allowed, as long as it does not openly fix the result.
Sanctions, the most common infringements, power unit parts and parc fermé.
From lightest to heaviest: reprimand, 5- or 10-second penalty (served at the pit stop or added to the final time), drive-through (passing through the pit lane without stopping), 10-second stop-go, grid drop at the next race, disqualification. Drivers also collect penalty points on their licence: 12 points in twelve months mean a one-race ban.
Exceeding track limits (a penalty comes after three warnings), causing a collision, gaining an advantage by leaving the track, speeding in the pit lane, impeding a driver in qualifying, not slowing under yellow flags, starting before the lights go out.
Each driver has a maximum number of power unit elements per season (engine, turbo, MGU-K, battery, control electronics) and of gearbox parts. The first extra element costs ten grid places, each one after that five; with too many places the driver starts from the back. That is how a fast driver can start last.
From the start of qualifying until the race the cars are under parc fermé: teams may only do routine work, without changing the set-up. Anyone who modifies the car loses their grid slot and starts from the pit lane.
How many points each position is worth and how to tell when the title is decided.
In the race the top ten score: 25, 18, 15, 12, 10, 8, 6, 4, 2 and 1. In the sprint the top eight: from 8 down to 1. The fastest-lap point has been gone since 2025. In a tie the driver with more wins comes first, then more second places, and so on.
The title is mathematically decided when the leader’s margin is bigger than the points still available to the second-placed driver. On our Standings page we work out the best and worst position still possible for every driver.
The points total tells only part of the story: look at retirements too (points lost to failures), the teammate comparison and the form over the last races. A driver with fewer points but more consistency may be stronger than the table suggests.
