Depending on the load point, the stack operates in the range of 220 to 280 volts. The storage battery operates over the range of 220 to 460 volts—a 3-way DC/DC converter in the engine compartment equalizes the difference compared with the fuel cell’s voltage level. 3-way power DC/DC converter. Hydrogen storage.

The outer skin of the show car is made of carbon fiber-reinforced polymer (CFRP); the occupant cell is a mix of CFRP monocoque and an aluminum structure. The battery recharges completely in about 20 minutes with 400 volt three-phase current, and in approximately one hour with 230 volt household current.
