The Norwegian Automobile Federation has published the results of an experiment in which two dozen modern electric cars took part. The goal was to check the power reserve declared by the automakers. It turned out that most of the test participants are able to drive more on one charge than promised, although there were some exceptions: three models could not reach the passport indicators. The outsiders were Polestar 2, Citroen e-C4 and Xpeng G3.
In addition to the mentioned Polestar 2, Citroen e-C4 and Xpeng G3, two Ford Mustang Mach-E and two Tesla Model 3 in different versions, as well as Volkswagen ID.3 and ID.4, Skoda Enyaq, Audi e-tron GT, Ioniq 5, BMW iX3, Mercedes-Benz EQA, Volvo XC40 Recharge, Citroen e-C4, Opel Mokka-E, Fiat 500, Honda e, Hyundai Kona and Mazda MX-30. All of them were on equal terms: with a 100 percent charged battery, electric cars drove along a given route until the charge ran out, while the pilots were not allowed to accelerate more than 110 kilometers per hour. The road combined city streets, countryside and mountain pass.
BMW iX3 showed itself better than others, which covered 556.2 kilometers without recharging, which is 106 kilometers or 20 percent more than the declared power reserve. Tesla Model 3 covered a greater distance – 654.9 kilometers, although the difference with the passport data is not so great (614 kilometers in the WLTP cycle). The leaders were also the rear-wheel drive modification of the Mustang Mach-E, on which the pilot drove 617.9 kilometers against the declared 610 kilometers. On average, most of the participants in the experiment had a power reserve six percent higher than promised.
As for the Polestar 2, Citroen e-C4 and Xpeng G3, they fell short of the declared figures of three, five and 12 kilometers, respectively.
In early 2021, Edmunds.com experts conducted similar range tests for electric vehicles sold in the United States. As with the Norwegians’ experiment, most of the subjects exceeded the stated range, but the Tesla Model S, Model 3, Model X and Model Y failed.
