Abstract: An electrical passenger car, the electrical passenger car including: at least two electrically driven motors; motor control electronics; sensors; and wheels, where the wheels include a first front wheel and a first back wheel, where the first back wheel has a radius at least 20% greater than a radius of the first front wheel, and where during acceleration of the electrical passenger car, the motor control electronics receive signals from the sensors and provide traction control delivering more power to one of the at least two electrically driven motors accordingly.

Abstract: An electrical family car, including: an electrically driven motor; and wheels with a radius larger than 90 cm. In such cars one of the dominating energy losses is directly related to the car axial to wheel friction. The car efficiency could therefore be increased by increasing the car wheel diameter which could yield a larger traveling distance for the same axial to wheel friction related energy loss.
