The Haas F1 Team introduced a unique adaptation of Ferrari’s “Flick Tail Mode” (FTM) during the Chinese Grand Prix, an aerodynamic solution leveraging exhaust heat. This move underscores the close technical relationship between the two teams and highlights Haas’s ability to rapidly implement innovations pioneered by Ferrari.
The system, mounted on the deformable rear structure ahead of the central exhaust, was developed by engineers under the leadership of Andrea De Zordo. Haas was able to quickly adopt this solution because the American team utilizes the power unit, gearbox, and rear suspension from Ferrari. This reliance on Ferrari components provides a clear pathway for technology transfer, allowing Haas to capitalize on advancements made by the Italian outfit.
The implementation of FTM comes as teams continue to explore every avenue for performance gains within the current Formula 1 regulations. The 2026 regulations permit an aerodynamic element on the deformable rear structure, provided the overhang relative to the rear axle does not exceed 60 millimeters. Ferrari strategically designed the rear of their SF-26 specifically to exploit this space, repositioning the differential and driveshaft further back within the gearbox. This design choice enables the FTM system to operate within the regulatory limits.

Haas unveiled its own version of the concept in Shanghai. The upper section of the rear structure around the exhaust is fitted with a metal cladding featuring a semi-rim and two small wing profiles designed to direct the hot exhaust gases upwards. Here’s intended to improve the efficiency of both the rear wing and the diffuser. Andrea De Zordo, now Technical Director at Haas, spearheaded this rapid implementation.
According to reports, the version implemented on the VF-26 is an initial iteration, but positive results have already been observed in Maranello. Both Ferrari and Haas are hoping to maintain a performance advantage with this innovation, one that other teams may discover difficult to replicate quickly. The close collaboration between the two teams, facilitated by the supply of key components, has clearly accelerated this development process.
However, not all Ferrari-powered teams can immediately benefit from this technology. Cadillac, similarly utilizing the Ferrari 067/6 power unit, is unable to implement the FTM system due to not having the specific Ferrari gearbox designed to accommodate it. This highlights the importance of the complete technical package – not just the engine – in maximizing aerodynamic performance.
Andrea De Zordo’s promotion to Technical Director in March 2024, after previously serving as Chief Designer, underscores Haas’s commitment to strengthening its technical capabilities. De Zordo’s experience at McLaren and Ferrari, combined with his current leadership role, positions him as a key figure in the team’s pursuit of improved performance. His appointment came after a period where personnel were seconded from Ferrari to Haas, a move driven by Formula 1’s cost cap regulations.
The success of this aerodynamic adaptation will be closely monitored in the coming races. The Chinese Grand Prix provided a valuable testing ground, and further refinements are expected as Haas continues to optimize the system. The team’s ability to quickly translate Ferrari’s innovations into on-track gains demonstrates the effectiveness of their technical partnership.
The next race on the Formula 1 calendar is the Miami Grand Prix, scheduled for May 5th. Teams will be looking to build on the developments made in China and further refine their aerodynamic packages. Haas will be aiming to continue its momentum and demonstrate the effectiveness of its Ferrari-inspired innovation.
