An automotive vehicle includes a vehicle body, a power transmission system, an energy storage device, a continuously variable transmission, and an electronic control device. The power transmission system includes a power source for driving the automotive vehicle. The energy storage device includes a flywheel. The continuously variable transmission interconnects the power transmission system and the energy storage device. When the automotive vehicle decelerates, the electronic control device connects the flywheel to the power transmission system through the continuously variable transmission, and transfers energy of the power transmission system to the flywheel. When the automotive vehicle accelerates and the electronic control device connects the flywheel to the power transmission system through the continuously variable transmission, energy of the flywheel is transferred to the power transmission system.
