The battery pack is a structural element of the vehicle and houses not just the cells but also all switch components and the battery management system. We’ve seen this skateboard design with the battery being a structural element before, and it typically performs well in crash testing.
In the GT XX, the power is sent from the battery pack to three motors packaged as two high-performance drive units. The front unit has a single motor, while the one in the rear has two. Math! Unlike pedestrian radial flux motors, the AMG.EA setup in the GT XX uses axial flux motors.
What are they? They are motors designed for the electromagnetic flux to run parallel to the motor’s axis of rotation. The large components in the motor are shaped like slim discs, and the stator is positioned between the two rotors.
The motor and gearsets are packaged together, with the rear combined drive unit doing most of the forward momentum. The front drive unit…
