    Abstract: The present disclosure provides a battery electric vehicle enables the driver to recognize whether the vehicle is driven in a motor driving mode or in a variable speed driving mode. The controller is programmed to control the display apparatus to display simulated rotation speed as rotation speed of the engine in the engine vehicle with simulated torque behavior when the variable speed driving mode is selected by the mode selector, and not to display the simulated rotation speed when the motor driving mode is selected by the mode selector. This enables the driver to recognize whether the vehicle is driven in the motor driving mode or in the variable speed driving mode.
