Why Barcelona and Sakhir were chosen as the circuits for the 2026 tests
The 2026 season is already just around the corner, and Formula 1 is preparing for one of the deepest technical revolutions in its history. With completely redesigned cars and brand-new regulations, Barcelona and Sakhir are back at the centre of attention as essential testing grounds to truly understand what the new era of F1 will look like.
But why were these circuits chosen for the tests of Formula 1’s new era?
Even though the year has only just begun, the 2026 season is approaching with unusual speed. The new regulations have shortened the winter break, and the FIA, fully aware of the scale of the changes, has decided to grant teams three separate test sessions, moving away from the single three-day format that had defined the past decade.
The first appointment will take place in Barcelona, which returns to hosting pre-season testing for the first time since 2022, when the introduction of ground-effect cars required an extended testing programme. In the past, Jerez was also a regular venue — especially in 2014, the debut year of the hybrid era — but in recent years Barcelona and Sakhir have taken on a dominant role.
Not because of tradition, but because of their technical characteristics.
Barcelona has long been considered a universal benchmark. A single lap includes slow, medium and fast corners, allowing teams to simultaneously evaluate aerodynamics, traction, balance and mechanical behaviour. Corners such as the famous Turn 3, a long and high-load curve, are crucial for verifying aerodynamic stability and comparing on-track data with CFD simulations and wind tunnel results. Slower sections, on the other hand, highlight traction and responsiveness.
If a car performs well in Barcelona, the common belief is that it can be competitive everywhere — a principle that was even more valid when the final-sector chicane was part of the original layout.
Sakhir, the ideal laboratory for traction, power and degradation
Bahrain perfectly completes the picture. The Sakhir circuit places a strong emphasis on traction, braking and acceleration zones, offering an ideal environment to analyse rear-end behaviour and power delivery on corner exit. This is where potential weaknesses in rear stability and power unit response tend to emerge.
From a tyre perspective, the two tracks present complementary challenges:
- Barcelona mainly stresses lateral wear, with long corners that test the car’s ability to manage energy over extended stints.
- Sakhir is a severe test for thermal degradation, thanks to high temperatures, repeated heavy braking and constant traction demands.
The climatic factor also plays a key role.
Barcelona alternates between cold mornings and warmer afternoons, ideal conditions for exploring tyre operating windows. Bahrain, by contrast, offers more stable and generally higher temperatures, perfect for cooling tests, power unit evaluations and long-run reliability checks.
Barcelona and Sakhir are not simply stops on the calendar. They are two complementary laboratories that allow teams to tackle every aspect of the new generation of single-seaters. From aerodynamics to traction, from tyre degradation to thermal management, the 2026 tests will be decisive in understanding who has interpreted the new regulations best and who will be forced to play catch-up.
The new era of Formula 1 begins here, between the kerbs of two circuits that, once again, will set the rhythm for the season.
