Each car was charged, stored and then tested in the same mild weather conditions, with the weight of an average driver and passenger on board. The climate control was set to 21deg C in every car and the headlights were left on throughout the test drive.
Where applicable, the cars were driven in ‘Normal’ mode, with minimum interference from regenerative braking, at What Car?’s 19.4-mile test track. A Racelogic Route Profiler ensured consistent driving styles along the route, which comprised simulations of stop-start traffic, rural roads and motorways.
Cars with batteries that accepted more than 60kWh in the initial phase of testing were driven along the route twice, while those with batteries that took more than 100kWh conducted three passes. After the driving phase, the testers measured the amount of energy required to refill the batteries, and were able to calculate each car’s 'Real Range' from the overall results.
The Kona EV had a Real Range of 259 miles, six more than the Jaguar I-Pace in second place.
See below for a rundown of the results, from the cars with the lowest 'Real Range' to those with the highest. For a more detailed breakdown of the test results, click on the link.
