"The folks over at CarWow might be a bit skeptical when it comes to stated range, especially when that range is estimated using the rather forgiving Worldwide Harmonized Light Vehicles Test Procedure (WLTP). That's why they've put a number of EVs through the ringer to figure out how much real-world range they actually get-and they've done it yet again with a fresh new batch."
"What CarWow found was interesting, at least to an EV nerd like me. Unsurprisingly, EV range was directly linked to the vehicle's overall battery size. However, the strange bit is that the real-world efficiency of every car in the test was nearly the same. But before we get into the specifics, let's talk about what the video actually tested. CarWow drove each car until it ran out of juice. It then recorded this number as the EV's real-world range."
"And using that number, it could calculate two very meaningful statistics: First is the vehicle's overall efficiency- this is pretty similar to judging a gas car's MPG rating. Essentially, it's a measurement of how many miles the EV can travel using a single kilowatt-hour of energy from its high-voltage battery. More miles equals more efficiency-it's a good read of how buttoned-up an EV platform really"
Five electric SUVs — Audi Q6 e-tron, BMW iX, Genesis GV, Kia EV9, and Polestar 3 — were driven until their batteries were depleted to record real-world range. The exercise measured miles-per-kilowatt-hour efficiency and total distance achieved before shutdown. Results showed that real-world efficiency figures for each vehicle were almost identical, while total range varied primarily with battery capacity. Measured ranges were often considerably lower than WLTP-rated estimates. The findings indicate that WLTP range figures can be optimistic and that real-world, end-of-charge testing reveals larger gaps between stated and achieved EV range.
