As we near the end of winter, Formula One is gearing up for a brand new season with brand new regulations. The attention has now shifted from Lando Norris’ maiden World Title win to a crucial phase of preparation, that is the Barcelona Shakedown.

It is an event that takes place behind closed doors, away from cameras and the public, but plays a vital role in shaping a team’s early season fortunes.

What is the Barcelona Shakedown?

To explain in layman terms, it is the first chance for teams to test and properly run their brand-new cars on the track with no mileage limits, meaning the teams can drive their cars for as long as they want. While the promotional running is capped at 200 kilometers per day on specific tyres, teams go the extra mile and log significantly more mileage during the Barcelona Shakedown, which then allows them to enable and validate key components, systems and power units in race conditions and not in a garage.

The Shakedown is held at the Circuit de Barcelona-Catalunya from January 26 to January 30, spanning five days, each team is allowed to run on only three of those. The teams are free to choose their days according to their will, they can base it on weather forecasts, parts availability and other strategic timelines. Some teams opt to start early while others may have to wait for key components to arrive and start later.

The main aim here, contrary to popular belief, is not to get the highest speed. Teams focus more on functionality and reliability. Engineers check cooling systems, test electronics and software behaviour and also confirm whether simulator data is translated accurately from the track. Barcelona provides a stress-free atmosphere for teams to test their machines, and for many it marks the first time that the car operated in full race configuration. Which is why privacy is vital to the event.

2026 brings in major technical changes, the cars will have a shorter wheelbase which will make them narrower, lighter and shorter, increasing their agility. Active aero, the most significant change, will impact the cars ability to adjust the angle of their front and rear wings during races. Which also means a goodbye to what we know today as DRS (Drag Reduction System), drivers will now be able to use active aero when they are within one second of the car in front, giving them an opportunity to use extra electrical energy to overtake.

Which is why teams are keen to shield their innovations, design concepts and aerodynamic solutions. F1 makes sure that the teams can experiment and troubleshoot without broadcasting their secrets.

Williams is the only team to not participate in the Shakedown. The teams will then move to Bahrain for two official tests in February before the season begins at Albert Park in Melbourne in March.
