Crash structure:

The main frame forms a survival cell due to the fact that the front wheel mounting provides a deformation distance of approx. 350 mm. In the event of a crash, the front wheel control arm mountings on both sides puncture a
strut and are deflected into a conically cut oval hole to dissipate the energy.

 

This process is supported by four deformation elements mounted on the frame structure, which also decelerate the movement of the control arm.

To prevent the relatively rigid front wheel penetrating the cell, the axle mounting has an asymmetrical design in the control arm. This means that in the event of a crash the front wheel will always perform a steering motion and will deform the control arm in a sideways direction. The pedals behind the control arm will thus remain in their position.

The deceleration in the event of a collision at a speed of 56 kph against a rigid wall is approx. 50g - a value at which the survival of the occupants can be assured in the event of a crash.

The roof frame will withstand a static load of 2 tonnes. Side impact forces are dissipated by a central node, whilst cross struts around the seats ensure a maximum intrusion of less than 125 mm with an ingress speed of less than 8 m/s.
