F1 2026 Pre-Season: Dates, Testing, and Round 1 Guide

The build-up to the 2026 Formula 1 season starts with a rush of car launches from January 15, 2026, followed by an intense testing program. This year’s pre-season includes a private five-day test window at the Circuit de Barcelona-Catalunya from January 26-30, and then two official three-day public tests at the Bahrain International Circuit (February 11-13 and February 18-20).
Racing finally begins with Round 1 at the Australian Grand Prix in Melbourne, set for March 6-8, 2026.
The 2026 season marks one of the biggest rule changes in F1 history. Lando Norris arrives as the defending World Champion after taking his first title in 2025, so expectations are sky-high.
Teams are doing more than just updating last year’s cars; they are building completely new machines under fresh rules that could totally change the running order we have seen in recent seasons.
F1 2026 Pre-Season Timeline and Key Dates
F1 2026 Team and Car Launch Dates
The "launch season" is when fans first see the new designs and shapes each team has chosen. The 2026 schedule starts with a large joint event in Detroit, Michigan, on January 15.
In a historic moment, Red Bull and Racing Bulls will appear alongside Ford to show off their liveries and celebrate the launch of Red Bull Ford Powertrains as an engine supplier. This is a big homecoming for Ford as they return to the top level of motorsport.
The weeks that follow are packed with more reveals. Haas will show its livery online on January 19, followed by a busy January 20 where Audi holds a major launch in Berlin for its official F1 entry, and Honda streams the reveal of its exclusive Aston Martin power unit from Tokyo.
Other key dates include Ferrari and Alpine both launching on January 23. A standout moment comes on February 8, when new entrant Cadillac will use a Super Bowl commercial to show its first-ever F1 livery to millions of viewers worldwide.
Official Pre-Season Test Session Dates
Testing in 2026 is split into three main blocks so teams have more time to work with the new rules. The first test is a private session at the Circuit de Barcelona-Catalunya from January 26-30. Over those five days, each team can choose any three days to run. With no TV cameras and no public timing, this session mainly acts as a shakedown for the radical 2026 cars.
After Spain, the focus moves to Bahrain for two official public tests at the Bahrain International Circuit. The first test runs from February 11-13, giving fans their first live look at the new cars on track.
Teams then get a short break to study the data before returning for the final pre-season test from February 18-20. These six days in Bahrain are the only chance for fans to see the full field in action before the first race of the season.
Round 1 F1 2026 Grand Prix Date
Racing gets underway on the weekend of March 6-8 at the Australian Grand Prix. Albert Park in Melbourne resumes its role as the season opener, providing a fast and scenic street circuit for the debut of the new 11-team grid.
With 22 drivers on the entry list, the atmosphere is expected to be intense as fans watch the first true battle of this new rules era.
Right after Australia, the paddock travels straight to Shanghai for the Chinese Grand Prix (March 13-15), which will host the first Sprint weekend of the year. This back-to-back start means teams must sort out reliability issues during pre-season, as there is very little time to fix major problems once the freight begins moving around the world.
F1 2026 Car and Team Changes To Watch
Major Technical Regulation Updates for 2026
The 2026 season is a full reset: every car is new, built under fresh chassis and engine rules. The biggest change is the power units, which now depend far more on electric power and run on 100% sustainable fuels. These changes have helped bring in new manufacturers like Audi and Red Bull Ford, and have led Honda to form an exclusive deal with Aston Martin.
On the chassis side, the cars are built to be smaller and more agile, with active aerodynamics being a key feature. These systems help reduce drag on straights and keep grip in the corners. The goal is to improve close racing and cut down on the "dirty air" problem that has made following other cars difficult in the past.
Engineers now face the tough task of managing complex energy systems in the new engines while also meeting the demands of the lighter, more compact chassis.
Notable Team Changes and Livery Reveals
The grid grows to 11 teams in 2026 thanks to the entry of Cadillac. The American brand joins with a driver lineup of Valtteri Bottas and Sergio Perez, giving the new squad strong, experienced drivers from day one.
At the same time, the Sauber name disappears as the outfit fully becomes the Audi works team, expected to run a striking livery in titanium, carbon black, and red, based on early previews.
The driver market continues to bring big stories. Lewis Hamilton heads into his second year with Ferrari, still chasing his first victory for the Scuderia. Over at Williams, Alex Albon and Carlos Sainz aim to build on the team’s impressive fifth-place finish in the 2025 championship.
With Adrian Newey set to take over as Team Principal at Aston Martin, the AMR26 launch on February 9 is one of the most anticipated events of the winter.

What Is F1 Pre-Season Testing?
Why Do F1 Teams Conduct Pre-Season Tests?
Pre-season testing links computer work to real track running. Teams spend countless hours in wind tunnels and running CFD (Computational Fluid Dynamics) simulations, but real-world laps are still the final proof.
The main aim is correlation-checking that what happens on track matches what the models and simulations predicted back at the factory.
Testing is also about reliability. A quick car is useless if it breaks down. Teams use test days to push every part to its limits, from the complex cooling systems of the 2026 power units to the strength of the gearbox.
It is also an important period for drivers to build "muscle memory" with their new cars, getting used to braking points, steering response, and balance with the 2026 chassis.
What Happens During F1 Winter Testing?
A normal test day follows a very detailed plan. You will often see cars running with "aero rakes"-large frame-like structures covered in sensors-to measure airflow around the car. Teams also apply "flow-vis" paint, a bright liquid that spreads over the bodywork as the car moves, letting engineers literally see how air travels over wings, sidepods, and other surfaces.
Running is usually divided into morning and afternoon sessions. In the morning, teams may focus on short "installation laps" and system checks. In the afternoon, they are more likely to carry out long race-style runs to study tire wear and fuel effects on the car’s handling.
It is also a key time for pit crews to regain their rhythm, often practicing dozens or even hundreds of pit stops to get back down to sub-two-second changeovers for Melbourne.
Where Will F1 2026 Pre-Season Testing Take Place?
Circuits Hosting F1 2026 Pre-Season Tests
The Circuit de Barcelona-Catalunya remains the go-to venue for the first private test thanks to its mix of different types of corners. It has fast bends and slow, technical sections, acting like a test lab where teams can see how their cars react under a wide range of conditions.
The late January slot also brings cooler weather, which is helpful for early checks on cooling systems before the teams head to hotter climates.
The Bahrain International Circuit hosts the two public test sessions. This track provides a very different challenge: rough tarmac, higher track temperatures, and strong winds. Features like the tricky downhill Turn 10 are famous for exposing problems with braking stability and front grip.
Since the Bahrain Grand Prix takes place later in the year (Round 4), the data from testing there is useful both for the start of the season and for the later Middle Eastern races.
How Does Pre-Season Testing Impact Round 1 Preparation?
What Teams Learn From Testing Data
By the final day in Bahrain, teams have a clear picture of where their car is strong and where it is weak. They learn how the car reacts when they change setup-if they add more front wing, does the car turn better or become nervous? They also gather key information about tire wear, which shapes race strategies for the first few rounds.
At the same time, testing is known for "sandbagging." Teams often hide their true speed by running with heavy fuel or low engine modes so rivals cannot easily judge their form. The smartest analysts focus less on single lap times and more on long-run pace, which gives a much better idea of who is really in contention for podiums in Australia.
Common Challenges Between Testing and the First Race
The two-week gap between the last day of testing in Bahrain and the Australian Grand Prix is extremely intense. If a team finds a serious issue with, for example, the floor or cooling during testing, they have less than 14 days to design, build, and ship updated parts to Melbourne. This is often when we see a "B-spec" or heavily updated version of a car appear, with major changes that were not ready in time for the tests.
Logistics are another major hurdle. Moving 11 teams, their cars, and tons of equipment from Bahrain to Australia is a huge operation. Any delays or problems during testing can affect the whole build-up, leaving mechanics and engineers working through the night in the Albert Park garages as they reassemble and prepare the cars.
The teams that can turn their testing findings into a strong "Race 1" setup most quickly are usually the ones leaving Melbourne with the strongest results.
