F1: updated suspension of Ferrari Mira Extra Stability

The Maranello team has developed a suspension solution that can improve the performance of Hamilton and Leclerc’s SF25 performance.

Last week, Scuderia Ferrari performed tests with a new suspension in Mugello, in Italy, with the drivers Lewis Hamilton and Charles Leclerc. Taking advantage of the break in the Formula 1 calendar, the team tries to recover the lost time to improve their performance and guarantee their first victory for the season.

THE Formula 1 He released a summary with everything that was discovered during these test days.

Ferrari aims to launch the rear suspensions already updated to the Grand Prix of Belgium, which takes place this weekend, after having tested Mugello.

The most evident change is on the front leg of the upper oscillating arm, now positioned a few centimeters lower than the previous model. This change follows a trend that began at the beginning of the season with Mercedes and was subsequently adopted by McLaren.

This change, together with the anti-Merge geometry of the front suspension, aims to reduce the variations of the car corner during braking and accelerations. This translates into a more stable aerodynamic base and, consequently, more uniform aerodynamic forces acting on the vehicle.

With a reduction in the difference in the rear height between low and high speeds, the anti-Merge system allows you to adjust the static height of the car (when arrested) to a lower value.

This change contributes to increasing the strength of inactivity throughout the speed range, in particular at low speeds, when the diffuser is further away from the ground and the air flow is slower. Keeping the car closest to the floor helps to preserve the air flow under the car adhered to the surfaces that generate this aerodynamic force.

The front leg of the upper oscillating arm of the rear suspension has been relegated (the new component is highlighted in yellow below the original), which increases the anti-reading effect.

However, any change in a racing car has benefits and challenges. A possible negative effect is that the pilot can perceive the car as less sensitive, since a reduction in diving movements and pitch can reduce the important signals used to understand the behavior of the car in certain situations.

Another problem relating to the lowest static height is that the floor can be excessively close to the soil at high speed, causing excessive contact and greater wear wear (the plate located under the car), overcoming the allowed limits. Therefore, the new suspension is likely to also include adjustments in the shock absorbitor – changes that are not visible externally.
