Electric Vehicles are classified into converted EVs which are converted from internal combustion engine (ICE) cars and original EVs which are designed as electric vehicles totally. Energy efficiency of a converted EV and an ICE car are about 21% and 14%, respectively. The problem to prohibit for spreading of converted EVs widely is that the driving performances such as range per charge, maximum velocity and acceleration are poor. If the following concepts are adopted in an EV, the performance of an EV could be increased amazingly: 1) choose new technologies to be able to minimize the energy consumption of an EV; 2) choose a drive system suitable for an EV; and 3) the whole vehicle of an EV is designed originally as an EV. The new EV including all these concepts is named "Original EV". As original EVs IMPACT, IZA and FEV are introduced. The range per charge at 40 km/h constant speed is 548 km and the maximum velocity is 176 km/h in IZA. The 0 to 400 m acceleration time of IMPACT is 16.7 sec. The most important feature of original EVs is that the energy consumption rate is much lower than that of the ICE car. In IZA it is about 1/2.8 times lower than that of same class ICE car when crude oil is used as the primary energy. In the future the EV should be developed as an original EV and the cost of the development should be shared by automobile companies, power companies and governments.
