FIA’s 2027 aero crackdown: Why Ferrari stands to lose the most. Ferrari could become the team most affected by the FIA’s proposed 2027 F1 regulation changes.

Ferrari could suffer most from FIA’s proposed 2027 Formula 1 regulation changes

The FIA is currently evaluating several areas of Formula 1’s next-generation cars that could undergo major rule modifications ahead of the 2027 season, particularly regarding aerodynamic downforce reduction. And according to growing paddock analysis, Ferrari could once again emerge as the team most heavily damaged by these changes.

The Scuderia has built a car that appears extremely strong from both an aerodynamic and chassis perspective, even if it still suffers from a significant horsepower deficit compared to Mercedes. However, the FIA is now considering regulation changes that could directly impact the technical concepts Ferrari has invested heavily in, potentially eliminating one of the team’s biggest competitive advantages.

The current generation of Formula 1 cars is already receiving extremely aggressive development, with the first major upgrade packages introduced in Miami reportedly delivering gains of around four tenths of a second per lap.

Aerodynamic load levels are now exceeding initial expectations, and the FIA is therefore studying ways to reduce downforce in specific areas of the car while also increasing the amount of usable energy available to drivers.

One of the governing body’s concerns involves tyre stress potentially becoming excessive as aerodynamic performance continues to rise, although Formula 1 is not yet considered close to that critical threshold.

The bigger issue is that nobody currently knows exactly how much downforce teams will ultimately generate by 2027 because constructors are naturally unwilling to provide the FIA with completely accurate performance data. According to reports from AutoRacer.it, the FIA has already requested preliminary CFD studies from several teams focused on specific aerodynamic areas. And this is exactly where Ferrari could face serious problems.

FIA evaluating diffuser changes and possible FTM ban

According to the same source, the FIA is considering reducing aerodynamic load through significant modifications to the floor design, making it simpler and reducing the number of aerodynamic winglets, while also redesigning the diffuser.

Among the solutions currently being evaluated are changes to the rear wing dimensions and height, together with a possible ban on aerodynamic elements positioned near the exhaust area. Such a severe restriction on the so-called Flick Tail Mode system would create enormous problems for Ferrari, which was reportedly the first team to present the concept to the FIA and has since developed a substantial technical advantage in that specific area.

Although some rival teams have already partially introduced similar concepts, Ferrari is still believed to maintain a clear edge regarding this technology. That area of the car currently generates a very significant amount of downforce, with lap time benefits estimated at roughly four tenths of a second.

Ferrari’s rear-end aerodynamic platform is also the section where Diego Tondi’s engineering group has concentrated most of its efforts.

Ferrari’s complex aerodynamic concept now under threat

The system itself represents an extremely sophisticated design that required countless hours of simulation work and wind tunnel testing. The Flick Tail Mode device uses exhaust gases even at low engine speeds to recover energy and optimise aerodynamic efficiency. Ferrari’s engineers and technicians reportedly pushed the concept to its absolute limit by exploiting the benefits of an extended diffuser, both by increasing its effective operating length and by cleaning airflow through turbulence displacement around the exhaust region.

The Maranello team effectively extended the diffuser upward to the maximum height allowed under the regulations, partially covering the exhaust area itself.

However, the FIA has been trying to limit or eliminate the aerodynamic use of exhaust gases since as far back as 2011.

For that reason, there is now a realistic possibility that the concept could either be heavily revised or removed entirely under the future 2027 regulations. If that happens, Ferrari’s entire 2027 project could require major redesign work in order to recover the lost downforce through alternative aerodynamic solutions. And considering how central this concept appears to Ferrari’s current philosophy, the consequences for the Scuderia could be extremely significant.
