One of the hottest topics when it comes to electric vehicles is electric vehicle range. Official range figures are provided by manufacturers, but real world performance can be vastly different depending on driving conditions, the climate and how the individual drives. Claimed range numbers for the BYD Sealion 7 are impressive, but in daily use, users are reporting mixed results. Actual range is dependent on factors such as highway speed, temperature and terrain. In ideal conditions some owners are reporting exceeding the official range, while in colder weather or at higher speeds the range has been decreased significantly. The question of whether the Sealion 7 is efficient enough to warrant use over competitors like the Tesla Model Y or Hyundai Ioniq 5 on public streets has not been settled, with various conditions determining factors that shape individual experiences.
