A claimed range of 300 miles sounds reassuring until a winter motorway journey, a headwind and a full passenger load reduce it considerably. Electric vehicle range is not a fixed property in the way that many buyers once assumed a petrol tank capacity to be. It is an estimate produced under specified conditions, then altered by weather, speed, road gradient, driving style and the demands made on the car’s heating or cooling systems.
This is not an argument against electric cars. Many owners find them quiet, economical and particularly well suited to ordinary daily use. But sensible decisions about transport are made by understanding limitations as well as advantages. The gap between laboratory figures and real journeys has long existed for conventional cars too. With electric vehicles, however, the consequences are more immediate because recharging takes longer than filling a tank and the available public network remains uneven in quality.
