After the closed-door tests in Barcelona, the world of Formula 1 is preparing for a promising 2026 season. The teams, although under the weight of a well-kept secret, are gradually revealing their strategies and innovations. With radical technical changes, this season could be a significant turning point for motorsport.
Secret but Revealing Tests
The winter tests in Barcelona have raised many questions. Was it really necessary to be so secretive? Certainly, the real “official” tests will take place in Bahrain, but this closed event has restricted the dissemination of images, leaving fans wanting more. However, despite some incidents and the absence of the Williams team, these initial sessions were anything but catastrophic. In fact, they revealed a surprising productivity, showcasing the hard work done over the winter. This year marks the largest technical revision in decades, and the teams seem ready to face the challenge.
It is crucial to note that the cars we have seen are only preliminary versions. With such strict rules, the pace of development is expected to be frantic. This first glimpse represents only a fraction of what we will discover in the coming months.
Constantly Evolving Aerodynamics
Among the notable innovations, the front wing particularly catches the eye. The FIA has emphasised limiting the effects of airflow, but teams maintain design freedom that translates into bold choices regarding active aerodynamics. Aston Martin and Mercedes, for example, have opted for a configuration where the nose supports are fixed to the second element of the wing, allowing the top part to move more.
This choice may seem restrictive, but it offers advantages in terms of design and functionality. The front wing of the Mercedes W17 perfectly illustrates this approach, with a configuration that optimises both performance and stability. Moreover, some teams, like Ferrari, seem to have set aside these adjustments, opting for more traditional designs. The diversity of solutions is fascinating, and it will be interesting to see how each team adapts its choices based on the circuits.

Redesigned Suspensions
The return of push-rod suspensions is another highlight of the innovations for 2026. Most teams have chosen this solution, abandoning the traction rods. This choice is not trivial: push-rod suspensions offer a lightness and accessibility that attract engineers. James Key, technical director of Audi, emphasises that this option can help reduce the overall weight of the car, a crucial aspect under the new regulations.
The trend towards anti-dive is also highlighted. McLaren already demonstrated boldness in this area last year, and this year is no exception. Changes in the mounting height of the suspension arms directly influence the car’s behaviour on the road. The new Aston Martin seems to take this concept to the limit with a bold design.

Redesigned Sidepods for Aerodynamics
The sidepods, often overlooked, acquire crucial importance here. Teams compete in ingenuity with designs reminiscent of old bargeboards, but with a completely different function. While the FIA seeks to minimise turbulence, some teams still aim to exploit the airflow effect to their advantage.
The first appearance of the Aston Martin AMR26 has particularly caught attention, with very aggressive sidepods and an innovative cut to optimise airflow. Newey, a master in the field, has once again demonstrated his talent with a design that could revolutionise the car’s performance on track.

Evolution in Engine Cover and Diffuser
The engine cover and airbox are also distinctive elements among the different teams. Aston Martin presents features inspired by recent Ferraris, particularly with its triangular airbox. This highlights the growing influence of personnel transfers between teams, allowing for interesting technical synergies.
Regarding the diffuser, it has been the subject of particular attention during the tests. With revised regulations limiting ground effect, teams seek to maximise diffuser performance to generate maximum aerodynamic load. Mercedes has introduced an opening in its diffuser, allowing for better airflow. Other teams, including Ferrari and Red Bull, have followed this trend, demonstrating that competition is fiercer than ever.

On the Way to Bahrain: A Promising Future
With only weeks until the start of the season, teams continue to refine their designs. The strategic game between teams intensifies, and everyone is examining each other’s work. As Neil Houldey at McLaren pointed out: “We have many, many photos of the other cars.” These exchanges of ideas could shape the future of F1 for years to come.
As we head towards Bahrain, expectations are enormous. The first impressions from the tests have only scratched the surface of a season that promises to be captivating and full of twists. Who will stand out in this new era? The answers will arrive soon on our screens!
