The real world range of popular EVs put to the test
and on Freeview 262 or Freely 565
Not a week goes by without one surveys declaring that EV buyers are no longer bothered by range anxiety while another is insisting they are still put off electric cars because they’re scared they’ll run out of charge.

However, there’s still a rightful amount of scepticism around the official ranges of these cars and questions over how far they can travel on one charge in real-world conditions.
To answer these questions car buying platform carwow decided to put six EVs with some of the longest claimed ranges to the test to see which would travel furthest and which got closest to its official figures.

Mainstream versus luxury
The test took six cars from mainstream and luxury brands - the Nissan Leaf, Kia e-Niro, Audi e-tron, Jaguar I-Pace, Mercedes-Benz EQC and Tesla Model 3 - and, after charging them to 100 per cent and leaving them overnight, headed north from London.
Each car’s air con was set at 20 degrees, a mobile phone connected to the infotainment system and the cruise control set to the motorway speed limit.

In terms of pure distance travelled, the Tesla came out on top, covering 270 miles before running out of charge. That’s not necessarily surprising given that it had the largest battery and longest official range.
However, it was Kia’s e-Niro which came closest to matching its official figures, its 255 miles was 90 per cent of the claimed 282. In contrast, the Tesla, with a claimed range of 348, covered just 78 per cent of the official distance.
The Nissan Leaf was the best performing after the Kia, managing 208 miles or 87 per cent of its claimed 239 miles.

Make and model | WLTP claimed range (miles | Range on test | % of claimed range achieved |
Kia e-Niro | 282 | 255 | 90 |
Nissan Leaf | 239 | 208 | 87 |
Audi e-tron | 255 | 206 | 81 |
Tesla Model 3 | 348 | 270 | 78 |
Jaguar I-Pace | 292 | 223 | 76 |
Mercedes EQC | 259 | 194 | 75 |
Running flat
To see what happens when the charge read-out hits zero, the testers drove each car on the motorway until they neared zero per cent charge then left and drove close to a charging point until the car stopped and could go no further. Five of the six vehicles were able to keep going for a significant amount of time despite showing a completely empty battery. However, when they did completely stop, most of the vehicles ‘locked up’ and proved difficult to move.
Mat Watson said: “We know that ‘range anxiety’ is a big concern for people thinking about switching from petrol to electric – no one wants to get stranded. But our test showed you could drive an average of 226 miles and all of the cars were able to keep going after their systems claimed their batteries were totally flat.

But that’s a similar figure to the percentage of potential range you’d get in a petrol or diesel car. Plus, in the real-world, these cars’ sat-nav systems would direct you to a nearby charging station long before you ground to a halt.”
