FIA shutdown ANOTHER F1 loophole after Red Bull and Mercedes controversy
The FIA have closed off a potential loophole in the 2026 F1 rules that Red Bull and Mercedes were involved in.
The controversy surrounded a trick with the geometric compression ratio, set to change from 18:1 to 16:1 for power units in 2026.
Red Bull and Mercedes were accused of manipulating the ratio to gain an estimated 15bhp advantage during a lap.
Rival manufacturers Audi, Honda, and Ferrari called for the loophole to be addressed.
The FIA also discovered a loophole in the fuel-flow meter rules, prompting changes for 2026 to prevent teams from exploiting the rules.
The latest changes involve introducing a single standard fuel-flow meter in all cars to prevent any manipulation that could alter performance unfairly.
