What's The Real World Highway Range Of Today's Electric Cars? We Test To Find Out

InsideEVs tests EVs at 70 miles per hour to find out their real-world highway range.

There are several variables that affect how far an electric car can travel on a single charge, including speed, temperature, topography, and other traffic conditions. 

This is why range ratings provided by the government, such as those used by the EPA and WLTP, 

are only predictions of what an EV user might anticipate from a combination of city and highway driving in largely favourable, but not ideal, ambient conditions.

But because the actual world is so very different, InsideEVs runs its own EV range testing at a constant speed of 70 mph.

About EV Range Tests Conducted By InsideEV

To be honest, our range testing aren't flawless. There are other factors, such as wind, traffic, and weather, that are just beyond our control. 

We nevertheless try to exert as much control as we can. 

We always charge up to 100 percent, adjust the tyres to the manufacturer's prescribed pressure, 

double-check the speedometer's accuracy with a GPS, and then either immediately or within a few miles get on the highway. 

We then go in lengthy circles at a steady speed of 70 mph to essentially return to our starting point.

Whenever possible, we repeat the test with a second member of the team on a different course.

When we do that, we average the results of the two tests.
