NOVELTY - The vehicle has an electric drive system (128) and another drive system independently driving two wheels of the vehicle, where the former drive system comprises a battery powering an electric motor (126) and the latter drive system is powered by a non-battery power source. The latter drive system comprises a motorcycle petrol engine provided with two cylinders. A controller automatically switches from the former drive system to the latter drive system when the battery of the former drive system reaches setting level. A solar panel powers a support system of the vehicle.    USE - Four-wheeled two axle front-wheel or rear-wheel drive electric vehicle e.g. passenger automobile, sports utility vehicle (SUV), bus and lorry. Can also be used as a three-wheel vehicle or vehicle with three axles.    ADVANTAGE - The vehicle allows the latter drive system powered by a non-battery power source to be an independent electric drive, so that a non-electrical portion is not intimately integrated with the electric drive, thus upgrading the electric drive by replacing appropriate components and the electric motor with power and better efficiency models and a battery assembly with higher capacity models, and hence realizing non-maturity of the vehicle to easily upgrade the vehicle. The vehicle allows the latter drive system to be operated at maximum power less than maximum power of the former drive system, thus allowing the drive systems to use electrical power such as solar power, wind power, hydraulic power, compressed air and bio-energy sources, to charge the battery.    DETAILED DESCRIPTION - The engine is powered by petrol, diesel and compressed air or natural gas. The support system comprise a vehicle fan, vehicle lightning e.g. head light, tail light and emergency light, vehicle heater and an electronic component e.g. radio, global positioning system (GPS), compact disk, telephone support and air-conditioner.
