To measure the electric driving range the end of the test criteria is reached when the vehicle is not able to meet the target curve, up to 50 km/h, or the maximum speed in pure electric mode, as declared by manufacturer, or when an indication from the standard on-board instrumentation is given to the driver to stop the vehicle or when the electrical energy storage device has reached its minimum level of charge. Then the vehicle shall be slowed down to 5 km/h by releasing the accelerator handle, without touching the brake and then stopped by braking. 4.2.1.4.
