Components 1’s governing physique the FIA has formally tightened up 2027’s technical rules to outlaw Ferrari’s exhaust wings.
pioneered the exhaust wing throughout pre-season testing in Bahrain, having apparently discovered a loophole within the 2026 technical rules to extract extra downforce from the rear of the automobile, utilizing exhaust gasoline to provide air to a tiny winglet perched atop the tailpipe.

This 12 months, groups had been allowed to put an aerodynamic system in that space of the automobile so long as it doesn’t exceed 60mm from the axle and, usually, that constraint wouldn’t permit the system to increase past the tip of the exhaust.
Nonetheless, as revealed by Motorsport.com in pre-season testing, Ferrari engineers managed to get round the issue by shifting the differential way back to doable, making the most of the house below the deformable construction. As a result of that space of the automobile was designed by Ferrari with that particular system in thoughts, which was internally dubbed FTM, that meant it was powerful for rivals to repeat it simply.
The exhaust wing is authorized proper now, however following talks with the FIA, the governing physique has now determined to tidy up the rules to dam Ferrari’s answer in 2027, avoiding designs getting uncontrolled.

Within the newest model of the F1 2027 technical rules, which was printed on Friday after being ratified by the FIA’s World Motor Sport Council in Macau, the FIA has applied an exclusion zone.
Article C2.3.7 reads: “Apart from tailpipe, no a part of the automobile could lie inside a proper round cylinder which intersects the planes XR = 385 and XDIF = 800, and whose axis is similar to, and diameter 20mm higher than, that of the precise round cylinder outlined in C3.9.2(g).”
Mercedes has been operating with a small bracket atop the tailpipe since Miami.

From Miami onwards rival groups, together with , discovered a unique loophole to make use of an exhaust tailpipe bracket and have it act as a winglet, even when it is much less highly effective than Ferrari’s baked-in answer. However that loophole now additionally seems closed after the FIA closely revamped the related article within the rules, C3.9, which locations additional restrictions on the location and form of the tailpipe and any adjoining bodywork.

Austria trials
Throughout Friday’s first free apply session, was seen driving his SF-26 with the exhaust wing hooked up, whereas photos present rookie driver was initially utilizing the system earlier than having it eliminated for the rest of the session.
It’s understood to be a comparative check between the 2 configurations for later occasions this 12 months. Having a rookie driver within the automobile anyway, as an alternative of standard driver , meant Austria FP1 was a chance to trial the set-up with little draw back.

Relying on the outcomes, the wingless set-up could possibly be deployed later this 12 months at decrease downforce circuits, similar to Monza, the place the advantage of the additional downforce may not outweigh the corresponding drag penalty.
Different 2027 clampdowns accredited by the FIA WMSC embody the place of the ground physique stays and their interplay with the sidepod bodywork, and additional restrictions on the suspension design and the behaviour of the dampers.
