An electrically-powered vehicle having a combination automobile frame and trailer, which are driven by a pair of electric motors located on the automobile frame. A battery is also located on the automobile frame, and a generator, along with a gas turbine for driving the generator, are located on the trailer. The vehicle can be operated with the trailer attached and the electric motors powered by a parallel combination of the battery and generator, or with the trailer removed and the motors powered by the battery alone. A controller turns on the gas turbine when the charge level in the battery drops below a first predetermined level and turns off the turbine when the charge level rises above a second predetermined level. Additionally, when the gas turbine is operating, its speed is maintained at a constant level, thereby maximizing its operating efficiency and yielding a minimum level of exhaust pollution.
