Electric vehicles (EVs) have become increasingly popular in recent years due to their environmental friendliness and low operating costs. One of the key factors that potential EV buyers consider is range, which refers to the distance an EV can travel on a single charge.

This article aims to provide a detailed comparison of the EPA and WLTP range ratings, highlighting their differences and similarities.
