Moveable Trumpets prohibition

In Simple Terms

F1 engines cannot have moveable trumpets or flexible air intake systems. All the piping that carries air from the turbo compressor to the engine cylinders must be permanently fixed in place, with only the throttle and pressure relief valves allowed to move.

• Moveable trumpets are completely prohibited in F1 engine design
• All air intake geometry from compressor outlet to cylinder inlet must be rigidly fixed
• Only throttles and pop-off valves are permitted to have moving parts in this system
• This rule ensures standardized and fair engine performance across all teams
