Motorsport’s governing body, the Fédération Internationale de l'Automobile (FIA), will roll out a revised engine testing process from June amid scrutiny over compression ratio restrictions. The move comes after paddock talk suggested Mercedes-AMG Petronas Formula One Team may have taken advantage of grey areas in the 2026 temperature measurement rules.
