摘要

The car (10) has electrical machines (17-20) designed differently on a front axle (11) and a rear axle (14), where each electrical machine is designed for given power on the front axle and designed for given torque on the rear axle. Small rotor diameter of the electrical machine at the front axle is smaller than that of the rear axle of the electrical machine. The electrical machine comprises a smaller maximum rotational torque at the front axle than at the rear axle of the electrical machine.
