FIA Confirms Ban on Ferrari’s Innovative FTM Exhaust WingÂ
By Hugo Harvey
The FIA has officially confirmed that Ferrari’s innovative FTM (Flick Tail Mode) exhaust wing concept will be outlawed from the 2027 Formula 1 season, bringing an end to one of the most talked-about aerodynamic developments of the 2026 campaign. The decision was approved by the FIA World Motor Sport Council as part of the governing body’s latest technical regulations, marking a significant shift ahead of Formula 1’s next generation of cars.
Ferrari introduced the concept during pre-season testing, quickly attracting attention throughout the paddock. The device, positioned around the exhaust outlet, was designed to manipulate the flow of hot exhaust gases to generate additional aerodynamic performance at the rear of the car. The concept proved to be one of the Scuderia’s boldest technical innovations under the current regulations.
Initially, Ferrari enjoyed a unique advantage, with customer team Haas later adopting a similar arrangement thanks to its shared rear-end architecture. Before long, however, rival teams found alternative ways to exploit the same regulatory grey area, triggering a rapid development race across the grid.
Teams including Mercedes, McLaren, Red Bull, Williams, Alpine and Cadillac all introduced their own interpretations after identifying a loophole within the technical regulations governing exhaust supports. While the individual designs differed, the FIA became increasingly concerned that the area could evolve into an expensive aerodynamic arms race that was never intended by the rules.
Rather than banning the concept immediately, the FIA chose to allow teams to continue using the exhaust wing throughout the current regulations while planning a permanent solution for the next rules cycle. The updated 2027 regulations introduce an exclusion zone around the exhaust tailpipe that effectively makes such aerodynamic devices illegal.
The timing of the announcement was particularly interesting, as Ferrari reportedly experimented during Friday practice at the Austrian Grand Prix with an SF-26 configuration that removed the exhaust wing entirely. Although the change was believed to be an evaluation exercise rather than a permanent switch, it highlighted that the team was already preparing for life without the system.
For Ferrari, the ban represents a setback after investing considerable engineering resources into developing the FTM concept. The solution required significant design compromises during the construction of the SF-26, including changes to the gearbox and rear-end packaging to ensure the aerodynamic element remained within the legal dimensions specified by the FIA.
Reports throughout the season suggested the concept delivered meaningful aerodynamic gains by improving rear stability and driver confidence, particularly through medium- and high-speed corners. While the exact performance advantage has never been officially confirmed, rival teams moved quickly to develop comparable systems once the benefits became clear.
The FIA’s decision reflects its desire to prevent increasingly complex aerodynamic interpretations from appearing around the exhaust area as Formula 1 prepares for another major regulatory reset in 2027. Officials believe restricting the development path now will help reduce unnecessary spending while keeping the focus on broader vehicle performance rather than niche aerodynamic loopholes.
Although Ferrari loses one of its most distinctive innovations, the Scuderia retains valuable technical knowledge gained from pioneering the concept throughout the 2026 season. That expertise could still prove beneficial as engineers search for alternative methods of generating rear downforce within the new regulations.
The decision is also expected to influence development strategies across the paddock. Teams that had only recently invested in their own exhaust wing solutions will now redirect resources toward concepts that remain legal under the incoming rules. With development of 2027 machinery already underway at most factories, the regulation change arrives early enough to allow designers to revise their aerodynamic philosophies.
For Ferrari team principal Fred Vasseur and technical leadership, the challenge now becomes ensuring the team’s competitive momentum is maintained despite losing a feature that had become central to the SF-26’s aerodynamic identity.
As Formula 1 continues to balance innovation with cost control and competitive fairness, the FTM exhaust wing will be remembered as one of the cleverest technical ideas of the current era. While its lifespan has been relatively short, its impact has been significant enough to prompt a direct intervention from the FIA something reserved only for concepts considered capable of reshaping the competitive landscape.
With the 2027 regulations now officially confirmed, attention will turn to what fresh innovations engineers can uncover within the next generation of Formula 1’s technical rulebook, as the relentless pursuit of performance continues.
