Best EVs for highway range: only 30 cars exceed 300 km in real test

French outlet L’Argus has published a large-scale highway range test of over 80 electric vehicles. The results reveal that fewer than 30 models managed to exceed 300 km of real-world range at 130 km/h, far below the WLTP figures advertised by manufacturers.
The top performer was the Mercedes EQS 450+, covering 495 km in total and offering 347 km of usable range between 80% and 10% charge. Close behind were the Volkswagen ID.7 Tourer Pro S and the Audi A6 Avant e-tron. Tesla’s Model Y and Model 3 also made the top 10. Among French brands, the Renault Scénic E-Tech ranked best, in 18th place with its 87 kWh pack.
Crucially, testers highlight that in everyday driving only about 70% of the battery is actually usable, as drivers keep a safety margin and rarely charge beyond 80% to save time. This cuts the effective highway range of many EVs down to around 230–270 km.
The study also underlines how aerodynamics matter most at motorway speeds: sleek sedans and wagons perform best, while heavy SUVs consume more energy and fall behind.
