Motor racing's governing body is currently hard at work putting in place outline chassis regulations for the next rules era that will kick off in 2026.
As well as a planned shift towards active aero to help reduce drag on the straights, the FIA has offered some more details about what else could be changing.
Speaking in an exclusive interview with Autosport's Italian language sister site it.Motorsport.com, the FIA's head of single seaters Nikolas Tombazis has said that the main shift will be in the size of the car.
"With the dimensions of the wheels, which will be narrower, plus with the rear wing and the car in general, we aim to reduce the weight of the cars by around 50kg," he said.
"So, it will be possible to see smaller single-seater cars: shorter and narrower. But we are talking about solutions that still need to be discussed.
"With the car on a diet, we will be able to reduce the cornering speeds a bit. Being lighter, they will go faster in a straight line, but will generate less aerodynamic load. So, we will need to increase the hybrid's energy recovery to ensure adequate lap performance."
The changes planned for 2026 have not been without controversy, as Red Bull earlier this year warned of the potential for 'Frankenstein cars' that would be impossible to race each other.
There were even concerns about drivers needing to change down gear halfway down straights to try to boost their hybrid systems.
