Ferrari's problems are related to the rear suspension design

      Lewis Hamilton won Saturday's sprint in Shanghai, but he did not have enough speed to fight for victory in Sunday's race, and after the finish he was disqualified for increased wear on the control bar under the bottom. The Italian publication Autoracer managed to find out the details of what causes led to the problems of Ferrari.

      According to them, the problem with Hamilton's car in the race is not related to either the new front suspension design or the aerodynamics. The increased wear of the bar is not the reason, but the consequence of the fact that the design of the rear axle does not provide sufficient rigidity, so the team has to adjust the height of the ground clearance when 100 kg of fuel is filled into the car for the race.

      It is believed that such problems were caused by the design of the rear suspension, approved back in July last year, along with a new gearbox.

      Similar mechanical suspension elements and gearbox are used in Haas, but since their car does not have as complex aerodynamics as Ferrari, and generates less downforce, in the case of Haas, the suspension design features do not affect the speed of the car.

      On the Ferrari SF-25, the combination of suspension design and aerodynamics causes the car to become too "soft" and lose efficiency. Something similar happened with last year's Mercedes car.

      When the SF-25 is in optimal conditions, as it was in the sprint with 35 kg of fuel in the tank, the car is fast and generates much more downforce than its predecessor. However, when leaving the optimal operating range, the downforce decreases and there is a strong instability of the rear of the car in turns.

      Maranello is busy looking for a solution, but at the moment it is too early to talk about specific dates, as the problem is quite serious. At the moment, engineers are working on updates in some areas – new parts should appear on the car during the fourth stage of the season in Bahrain.
