Mercedes briefly tested a new interpretation of Ferrari’s FTM (flick tail mode) system during the Madrid Grand Prix, according to official Formula 1 sources.
This technology, present on Ferrari’s car since pre-season testing, partially blocks the exhaust gas outlet to increase their force and direct them upwards. This improves the airflow exiting the diffuser and energizes the airflow under the rear wing, providing an aerodynamic advantage.
However, Mercedes removed this modification after a short trial and used the same setup as in the previous race at Monza for the remainder of the weekend.
