Electric vehicles improve every year, and the range is higher in new models by a significant amount (on average) from 2011 to the 2017 model year.

The US DOE’s Office of Energy Efficiency & Renewable Energy discovers that in 2011 all-electric cars were rated by the EPA between 63 and 94 miles, and the median range was 73 miles.

The median is the value separating the higher half of a data sample, from the lower half.

Now for 2017, EPA ratings varied between 58 miles (smart fortwo Electric Drive Coupe) and 335 miles (Tesla Model S 100D), with median jumping up to 114 miles.

Ranges (median) increased by 41 miles, or 56% over the 6-year period.

Note: Median is based on the models listed in the supporting data spreadsheet; some of these AEV models are available with different battery capacities/body styles, which have shorter ranges.
