The drive components (motor, two-stage 1-speed transmission) of the HyMotion are in the engine compartment of the car as are the hydrogen fuel cell stack; the cooling system; a tri-port converter that regulates the voltage between the electric motor, the fuel cell and the lithium-ion battery; and the turbo compressor.

Meanwhile, outside the stack the electrons supply the electrical power. The entire fuel cell operates in the voltage range of 230 to 360 volts. Under many operating conditions, it equalizes the voltage, enabling the electric motors to operate at their maximum efficiency of 95 percent.

Two more 120 kW electric motors are at the front axle. The fully electrically driven front axle allows individual acceleration and braking of each front wheel, and therefore selective torque distribution (torque vectoring) for particularly high levels of vehicle dynamics. Each is connected to a front wheel via a reduction gear.
