EPA (United States) and WLTP (Europe, the UK and many other markets) are both official range tests, but they use different driving cycles and rules, so the same car gets two different numbers. This table puts the published figures for the same versions side by side. None of it is our own testing; every figure links to its source.
How to read the table
The EPA / WLTP range column is the EPA range converted to kilometres, divided by the WLTP range. For every model listed here the EPA figure is the lower of the two. The gap differs from car to car, so it is not a conversion factor: you cannot turn a WLTP number into an EPA one by multiplying.
The efficiency columns compare the EPA figure in kWh/100 mi, converted to Wh/km, with the WLTP figure in Wh/km. Converting the unit does not convert the test: both cells stay the result of their own cycle.
Which figure should you use?
The one published for your market, for every car you compare. A US buyer should compare EPA with EPA; a European or UK buyer, WLTP with WLTP. Comparing one car’s WLTP range with another car’s EPA range is the most common way to pick the wrong car. Neither figure is a promise for fast motorway driving in winter.
To switch between Wh/km, kWh/100 mi and mi/kWh, use the converter in Wh/km explained.
What is left out
Only versions with both a published EPA and a published WLTP range are listed. Cars sold in only one market are left out rather than estimated.
