Highway Range for Electric Cars

How far an electric vehicle goes on a single charge depends on many factors, including speed, temperature, topography, and other traffic conditions. This is why government-backed range ratings like the EPA and WLTP estimate what an EV owner can expect in a combination of city and highway driving in mostly favorable, albeit not ideal, ambient temperatures.

The real world is entirely different, which is why some third party EV market watchers conduct their EV range tests at a constant speed of 70 miles per hour.

A change in temperature as little as 10° F (5.5° C) can have a meaningful effect on an electric car's range. However, these 70 mph range tests are helpful because they provide another data point for potential customers looking for as much information on driving range as possible.
