Revealed: The FIA’s plans for "nimble" 2026 F1 cars and moveable aero
The changes in Formula 1 for 2026 include new regulations for the power units, with a switch to fully sustainable fuel and modified turbo-hybrids. The move has convinced Audi to join and led Honda to reverse their decision to leave. Not only the engines, but the cars themselves will undergo major revisions to improve the racing experience. The FIA has provided some details regarding the chassis changes, with plans for smaller, lighter, and more nimble cars. Car dimensions will be reduced, including a shorter wheelbase and narrower width. The aim is to reduce the weight limit by 40 to 50 kilograms and enhance the agility of the cars. Another important aspect of the changes is a reduction in downforce, which will alleviate the load on components and further contribute to weight reduction. The FIA also intends to introduce 16-inch wheel rims instead of the current 18-inch ones. Overall, the focus is on creating more robust racing with less reliance on downforce, while ensuring that cars can follow each other closely.
