The past project phase was marked by a change of electric motor supplier and the subsequent dealing with these complications that affected the design.

Unexpected modifications

During the tender for the electric motors, we were forced to change the supplier. This required additional design modifications to the sub frames and gearboxes. The frames had to be adapted to the new build as well as to marginal changes in wheel suspension.


Gear ratio optimisation (2nd version)

The drive ratio was modified synergistically. However, the e-Bullet project envisages interchangeable gears in several variants. The individual gears can be changed and thus the driveability of the entire car can be modified. Finally, the team is to be commended for the exemplary optimisation of the size and position of the gearbox. These modifications have a positive effect on the car’s moments of inertia, while achieving a better mass distribution.
