FSE.11

When developing the 11th generation, the team bet on the evolution of last year’s single-seater, which showed its potential and took 2nd place at last year’s races in Spain and Croatia.

Thanks to advanced Fluent Adjoint simulation technology, the team improved the vehicle’s aerodynamic properties while reducing the weight of the aero package.

Lightening was also achieved in the carbon chassis, axles and gearboxes.

The electronics have also been optimized. The new temperature measurement units with a decentralized system saved more than 100 meters of wires, which corresponds to a third of the length of the original cabling.

The new steering wheel unit offers the possibility of adjusting the display and setting parameters for individual pilots.
