Formula 1 does not accept walk-ins. Every driver on the 2026 grid earned their seat by climbing a ladder that starts in karting and passes through a series of junior championships, each one faster, harder, and more expensive than the last.
If you have ever watched an F1 race weekend and wondered what the F2 and F3 races running alongside it actually are, or how a teenager from Bologna ends up replacing Lewis Hamilton, this is how it works.
## How karting leads to single-seater racing
Almost every professional racing driver starts in karts, usually between the ages of six and ten. Karting teaches the basics: racecraft, reflexes, how to fight for position wheel to wheel. Max Verstappen, Lando Norris, Charles Leclerc and Lewis Hamilton were all karting champions before they ever sat in a racing car.
The jump from karts to cars typically happens around age 15. That first step is Formula 4.
## What Formula 4 is and why it matters
Formula 4 is the entry point to single-seater racing. The cars produce around 160 horsepower, reach roughly 240 km/h, and run on circuits rather than karting tracks. Several national F4 championships exist around the world, including series in Italy, Germany, Britain, and the United States.
The cars are identical within each championship. That is deliberate. When every driver has the same machinery, results reflect talent and racecraft rather than engineering budgets. The same principle applies all the way up to F2.
Kimi Antonelli, who now [leads the 2026 F1 championship with Mercedes](https://tarmactimes.com/en/f1/articles/kimi-antonelli-claims-maiden-f1-win-in-china-to-become-second-youngest-winner-in-history/psxmc5), won both the Italian and German F4 titles in 2022 at the age of 16. Oliver Bearman, who races for Haas in 2026, won the same Italian F4 championship a year earlier.
## Formula Regional: the step between F4 and F3
Between F4 and F3 sits Formula Regional, a level that did not exist a decade ago. The most prominent series is FRECA, the Formula Regional European Championship, which races at many of the same European circuits that F1 visits.
The cars are faster than F4 but slower than F3, with around 270 horsepower. For drivers coming out of national F4 championships, it serves as a bridge to international competition and more demanding machinery.
Antonelli won the Formula Regional European and Middle East titles in 2023. That was the last step before Mercedes made the unusual decision to skip him past F3 entirely and put him straight into F2.
## What is Formula 3 and how does it differ from F1
Formula 3 is the first rung of the FIA's international single-seater ladder that races directly alongside Formula 1 at grand prix weekends. The cars are built by Dallara, produce around 380 horsepower, and reach top speeds of about 270 km/h.
Every team runs the same chassis and engine. Pirelli supplies the tyres. The differences between cars come down to setup choices and driver input, nothing else.
F3 seasons typically feature around 24 races across a calendar year, split between sprint races and feature races. Grids are large, usually 30 cars, which makes the racing dense and teaches young drivers how to survive in traffic, manage restarts, and fight for position in tight packs.
The current FIA F3 championship was formed in 2019 by merging two predecessor series, GP3 and European Formula 3. Before that merger, Leclerc won the GP3 title in 2016, Russell won it in 2017, and Norris won the European F3 championship in 2017. All three were on the same level of the ladder. For most drivers, F3 is where F1 teams start paying serious attention.
## What is Formula 2 and how drivers reach F1 from it
Formula 2 is the final step before F1. The cars are significantly faster than F3, with around 620 horsepower from a turbocharged V6 engine, and top speeds above 320 km/h. Like F3, it is a spec series built around identical Dallara chassis.
F2 also races on the same weekends as F1, on the same circuits, which means team bosses and scouts are watching from the paddock. Each weekend features a sprint race and a feature race, and the feature race includes a mandatory pit stop, introducing the tyre strategy element that is central to F1.
A season in F2 costs several million euros. Some drivers are funded by F1 team academies, such as the Ferrari Driver Academy or Red Bull's junior programme. Others bring personal sponsorship. The financial barrier is real, and it does shape the grid.
Verstappen is the exception that proves how unusual his path was. He skipped F2 entirely, moving from a single season in the European Formula 3 Championship directly to F1 with Toro Rosso in 2015 at the age of 17. He finished third in that F3 season. That route would be nearly impossible today.
Most recent F1 graduates came through F2 in the conventional way. Bearman finished sixth in the 2023 F2 championship and spent a second season in the series before stepping up to Haas. Isack Hadjar, who races for Racing Bulls in 2026, came through the Red Bull junior programme via F3 and then F2.
## How the FIA Super Licence controls who can race in F1
Even winning every junior championship does not automatically open the door to F1. A driver needs an FIA Super Licence, which requires accumulating a set number of points based on finishing positions in recognised championships.
Winning the F2 title earns enough points on its own. Strong results in F3 or other FIA-sanctioned series can also add up. The system is designed to ensure that no driver reaches F1 without enough competitive experience, regardless of funding.
Drivers must also be at least 18 years old, a rule introduced after Verstappen's debut at 17 prompted a rethink. Antonelli received a waiver to earn his Super Licence at 17, though he did not race in F1 until he was 18.
## How much does it cost to go from karting to F1
The financial side is rarely discussed in the same breath as the sporting side, but it shapes the ladder as much as talent does.
A competitive season in karting costs upwards of 50,000 euros. F4 can reach 200,000 euros. Formula Regional and F3 are in the range of 500,000 to over a million. A seat in F2 costs between two and three million euros per season, sometimes more.
By the time a driver reaches F1, their family, backers, or academy sponsor may have invested several million euros across a decade of junior racing. Lewis Hamilton's father famously held multiple jobs to fund his son's karting career, and Hamilton was signed to the McLaren junior programme at age 13. That combination of talent and early backing is more the rule than the exception.
## What F1 team academies do and why they matter
Most F1 teams run junior driver programmes that identify talented teenagers and support them through the ladder. Ferrari, Red Bull, Mercedes, McLaren, Alpine, Williams, and Sauber (now Audi) all operate academies.
These programmes cover some or all of the costs of junior racing in exchange for the option on a driver's services if they reach F1. They also provide simulator time, fitness coaching, and media training.
The academy system has produced the majority of the current F1 grid. Leclerc came through the Ferrari Driver Academy. Norris through McLaren's programme. Antonelli through Mercedes. Hadjar and Lawson through Red Bull. The independent route, arriving in F1 without any factory backing, still exists but has become rarer.
## How F1, F2 and F3 compare on speed and technology
The gap between the three series is large.
F1 cars produce around 1,000 horsepower from hybrid power units and can exceed 360 km/h. They generate enormous downforce and subject drivers to forces above 5G in high-speed corners. Each team designs and builds its own car, spending hundreds of millions per season under the cost cap.
F2 cars are roughly 15 to 20 seconds slower per lap than F1 on a comparable circuit. F3 cars are slower again. That gap reflects the difference in power, aerodynamics, and tyre performance, but also the fact that F2 and F3 are spec series where development is frozen. The cars are tools for measuring drivers, not engineering competitions.
One way to see the gap: at Spa-Francorchamps, an F1 car laps in around 1 minute 43 seconds. An F2 car takes roughly 1 minute 57 seconds. An F3 car is closer to 2 minutes 12 seconds.
## Why F2 and F3 race on the same weekends as F1
This is not a coincidence. The FIA structures the calendar so that F2 and F3 serve as support races at grand prix weekends. It gives junior drivers exposure to the circuits, the teams, and the atmosphere of an F1 event.
It also means fans at the track or watching broadcasts can follow the careers of future F1 drivers before they arrive on the main grid. Antonelli's breakthrough F2 wins at Silverstone and the Hungaroring in 2024 happened in front of the same crowds and cameras that would watch him race in F1 a year later.
For F1 team bosses, having the junior series on the same weekend is practical. They can watch qualifying, assess racecraft, and talk to drivers in person. Many F1 contracts have been influenced by what a team principal saw from the F2 paddock.
