225 kW system output. The ID. ROOMZZ is powered by two electric motors. The front coaxial drive generates 75 kW while the rear electric motor with multi-step transmission generates 150 kW. The combination of both motors results in a system output of 225 kW. The rear axle provides propulsion as standard. An “electric propshaft” distributes the power of the 4MOTION four-wheel drive between the front and rear axles within fractions of a second once this becomes necessary due to driving dynamics. In addition, the ID. ROOMZZ can be continuously driven in four-wheel drive mode. Both motors are supplied with energy by a lithium-ion battery in the vehicle floor. The battery has an energy content of 82 kWh. Power electronics on the front and rear axle control the flow of high-voltage energy between the motors and the battery. Power electronics convert direct current (DC) stored in the battery into alternating current (AC). The on-board electronics are supplied with 12 volts via a DC/DC converter. Ideal weight distribution (approaching 50:50) is achieved by placing the battery in the middle of the vehicle floor and the drive units at both the front and the rear. The result: extremely agile and safe handling. The fully redeveloped running gear also has a significant influence on this, featuring electronic damping control, a multi-link rear axle, and a McPherson front axle.
Driving performances and range. The ID. ROOMZZ can accelerate to 100 km/h in 6.6 seconds; the maximum speed is capped at 180 km/h. The range of the concept car in the NEFZ cycle (China) is up to 475 kilometres, while in the European WLTP cycle the maximum range is 450 kilometres. The battery is charged via an inductive interface. Conventional charging via a plug is also possible.
