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.
