Ferrari has chosen to continue using a pull-rod rear suspension design and has explained why it decided not to follow Mercedes and adopt the push-rod system that Red Bull has used successfully. Red Bull’s push-rod system has allowed their cars to perform well at various ride heights under the current ground effect aero regulations. In contrast, Ferrari has struggled to manage their cars, particularly the SF-23 from last year. In an effort to catch up with Red Bull, Ferrari has made significant changes to their car concept for 2024, but they have not switched to a different rear suspension system. Ferrari Technical Director Enrico Cardile stated that they tested a pushrod suspension for a couple of years, but ultimately decided to stick with their current pull-rod system. Cardile also mentioned that they have made revisions to the suspension configuration, particularly in the rear where the inboard suspension is located differently inside the gearbox. The front suspension, however, remains similar to last year’s concept.
Ferrari’s focus in developing the SF-24 has been on drivability, aiming to create a car that allows drivers to comfortably achieve high performance. The team considered alternative suspension layouts during the development phase but ultimately decided to stick with a pull-rod setup for the third consecutive year. This choice sets Ferrari apart from Red Bull and Mercedes, who have switched to a push-rod system. Aston Martin, as a Mercedes customer, has also adopted the push-rod route due to inheriting various components. McLaren, a strong rival to Ferrari in 2024, also utilizes a push-rod layout at the rear. This divergence from their competitors gives Ferrari the opportunity to gain an advantage or potentially fall behind, depending on which concept proves superior throughout the season. Despite the risks, Ferrari’s investigations have led them to believe that they have made the right choice, and they will continue to assess the performance of the SF-24 as they further develop it on the track. According to Cardlie, the team found a satisfactory compromise with the current suspension layout, taking into account factors such as aerodynamic performance, weight, and suspension compliance. For the upcoming season, Ferrari does not plan to make any changes to the suspension layout and will evaluate their progress during the development process. So far, they are content with the current configuration.
