Ferrari could be facing a major setback ahead of Formula 1’s new engine regulations, with rival manufacturers reportedly prepared to support an FIA proposal to outlaw blown exhaust technology from 2027.
The controversial system, known internally as Ferrari’s FTM concept, first appeared during the second pre-season test in Bahrain earlier this year. The Italian team later introduced an upgraded version at the Miami Grand Prix, where paddock rivals quickly began questioning its legality and long-term impact under the sport’s incoming rules package.
According to reports from Motorsport.com, the FIA is now planning a formal vote involving all current F1 power unit manufacturers to determine whether the blown exhaust concept should remain legal beyond 2026. Ferrari are said to be the only manufacturer opposing the proposed ban.
Meanwhile, rival engine suppliers including Mercedes-Benz, Red Bull, Audi and Honda are reportedly ready to vote in favour of removing the design from the next generation of power units.
Ferrari’s system centres around a metal plate positioned over the lower section of the exhaust exit, redirecting airflow in a way that creates additional aerodynamic benefits. While the concept reportedly sacrifices between seven and 13 horsepower due to restricted exhaust flow, insiders believe the aerodynamic gains more than compensate for the loss.
Some estimates suggest the innovation could be worth as much as half a second per lap under the right conditions, making it one of the most influential technical developments seen so far under preparations for the 2027 rules era.
That potential performance advantage has understandably alarmed Ferrari’s competitors, especially as teams continue working on entirely new chassis and engine concepts for the future regulations. Concerns have also reportedly been raised about escalating development costs if rival manufacturers are forced to pursue similar systems to remain competitive.
The FIA has not yet officially confirmed when the vote will take place, but discussions are believed to be ongoing between technical delegates and manufacturers behind closed doors. If the proposal passes, Ferrari may be forced to abandon a concept that many believe could have provided a significant edge in the next generation of Formula 1.
The situation has already sparked intense debate across the paddock, with some teams arguing the system represents clever engineering innovation, while others believe it goes against the FIA’s intention of simplifying future power unit designs and reducing aerodynamic dependency.
