F1 2026: How teams may use floor flexibility to reach weight targets. FIA and the F1 teams are discussing more flexible 2026 floor regulations to help reduce car weight.

Weight will be one of the most difficult targets for the agile 2026 cars. After many years, the FIA has decided to reduce car mass, whereas until now we have seen a gradual increase, leading to F1 cars weighing around 800 kg including an 82 kg driver.

The 2026 regulations lower the minimum weight to 768 kg, a nominal reduction of 30 kg. In reality, teams will need to shed 60 kg to reach the limit, as power units and accessories are expected to grow from 120 kg to 150 kg next season.

It’s clear that achieving this weight reduction will be challenging. According to paddock sources, it is likely that, at least initially, many cars will exceed the limit.

Given this concern for chief designers, the upcoming TAC will discuss increasing floor flexibility. The intention is not to gain aerodynamic advantages, but rather to reduce the number of carbon layers to save weight.

Even though 2026 cars are already in an advanced stage of design and construction, with testing scheduled in Barcelona from January 26 to 30, it is highly likely that the TAC will produce a proposal supported by all eleven teams, as it would make reaching the weight target easier.

However, this remains conditional. If even one team that feels ahead in reaching the 768 kg limit opposes the proposal, it could be blocked at the next F1 Commission meeting.

Indirectly, the idea of a more flexible floor could also help reduce costs under the Budget Cap, giving hope that the proposal passes the first technical hurdle. Whether the same confidence will carry through to the F1 Commission, where experienced team principals will debate, remains to be seen.
