A July ~~31,~~ 31 2026 Geotab analysis of more than three million trips in Germany found that driving speed is the primary cause of electric‑vehicle range loss in summer, with aerodynamic drag cutting range by up to 40 % at 128 km/h. The study highlighted that doubling speed roughly quadruples drag, dramatically shortening the distance a 65‑kWh van can travel. Later the same day, ADAC’s test of a Kia EV6 in Poland showed that mounting two bicycles on the roof adds significant aerodynamic resistance. At speeds around 120–130 km/h, energy consumption rose 25‑34 %, reducing practical range by 20‑25 %. The results illustrate how external accessories further exacerbate the speed‑related drag effect, underscoring the importance of aerodynamics for real‑world EV mileage. Together, the findings emphasize that both high cruising speeds and added drag from roof‑mounted loads can substantially diminish electric‑car range, prompting drivers to consider speed management and accessory choices to preserve battery endurance.
