The FIA has updated Formula 1's 2027 technical regulations to prohibit exhaust wings similar to the design Ferrari introduced this season.
Formula 1's governing body approved the changes after ratification by the World Motor Sport Council in Macau. The updated rules include an exclusion zone that blocks the aerodynamic device Ferrari developed using a loophole in the 2026 regulations.
Ferrari first ran the exhaust wing during pre-season testing in Bahrain. The design channels exhaust gas to a small winglet on the tailpipe to generate extra downforce. Rival teams, including Mercedes, later adopted smaller brackets on the tailpipe starting from the Miami Grand Prix.
The FIA published the revised regulations on Friday. Article C2.3.7 now prevents any car part except the tailpipe from occupying the defined cylindrical space. Additional restrictions cover floor body stays, sidepod bodywork, suspension design and damper behaviour.
During Friday's first practice session at the Austrian Grand Prix, Lewis Hamilton tested Ferrari's SF-26 with the exhaust wing fitted. Rookie driver Dino Beganovic used the device briefly before it was removed.
