2026 F1 car analysis: innovations and (gross) errors in latest FIA renderings

2026 F1 car analysis: innovations and (gross) errors in latest FIA renderings. The FIA has released new renderings of the 2026 cars, featuring some big errors.

We are approaching the debut of the new 2026 cars in the wind tunnel. These cars are expected to bring more on-track excitement with many more overtakes and battles on the asphalt strip where they will race. After several weeks since “Issue 9,” the FIA has released the latest renderings of the 2026 cars, which include some innovations but also errors.

When comparing the latest official renderings to those previously shared on social media, there aren’t many differences. However, by analyzing the crucial areas of the cars in detail, we can spot some refinements. Specifically, these can be found on the two front and rear wing surfaces. Here, as expected, we will have two configurations, X and Z Mode, for high and low aerodynamic downforce.

Compared to the unofficial renderings, those released by the FIA show some small changes in the profiles. Specifically, the horizontal element on the outer side of the endplate is smaller and has a more complex geometry. Additionally, the vertical panel has been reduced in height, cut to reduce vortex generation.

At the rear, there are also some differences. One of the most notable is the shaping of the flaps, which are now more “angular” and less rounded. However, this new geometry may not be final and could undergo small variations based on the teams’ interpretations. The movement of the rear flaps has also been clarified, with the mainplane remaining fixed while the two upper flaps are free to rotate.

Gross error in the rendering production
While observing the rendering of the car presented by the FIA, we were able to spot some of the external differences. These shapes are of course subject to variation, as teams will be able to work on the volumes of the different working areas.

However, in analyzing the shapes, a keen eye noticed an error in the rendering production. Observing the front suspension of the new cars, we can see a pull-rod setup. This does not indicate that it will be the most effective on the upcoming cars. However, it is precisely on this system that we find an error made by the FIA. Specifically, there is a missing suspension link, particularly on the left side of the car.
