Most EV owners have experienced the dashboard predicting plenty of range, only for a steady motorway climb to chew through the battery twice as fast as promised. We’ve got used to doing mental math on the fly, subtracting twenty percent from whatever number the brochure promised just to stay out of trouble. When an automaker claims its flagship luxo-barge can cross a small country without touching a plug, the natural reaction is to doubt and wait for independent road testers to run the battery flat.
That’s why the latest evaluation from the testing team at Edmunds is worth paying attention to. They took a 2027 Mercedes-Benz EQS 450+ out on their standard range loop and drove it until it covered 867 km on a single charge.
