ELECTRIC CARS - MOTORWAY SPEEDS (RANGE DIFFERENCES)

EV Channels Review

This video investigates the real-world range differences experienced when driving an electric vehicle at economical "truck speeds" (around 60 mph) versus typical UK motorway speeds (around 70 mph). The reviewer, driving a Tesla Model 3 Standard Range Plus, found that driving at 60-62 mph yielded approximately 5.1 miles per kilowatt-hour. In contrast, driving at 70 mph resulted in a significantly lower efficiency of about 3.8 miles per kilowatt-hour. This translates to an estimated range loss of 23-27% when opting for faster motorway speeds. The reviewer highlights that while driving slower may not always result in arriving later due to the need for charging stops when driving faster, the advent of high-power charging can shift this balance. The video concludes that the choice between economical and faster driving depends on factors like charging infrastructure availability and personal preference, with faster charging potentially favouring quicker journeys despite the range penalty.
