AI generated from our expert reviews

Both electric SUVs have brakes that are easy to control and judge at lower speeds, and in both cars the rear seats recline for added comfort on longer drives. When it comes to the drive, the BMW iX3 provides a driving position that is spot on, whereas finding an ideal position in the BYD Sealion 7 can be tricky because you sit very high. On country roads, the iX3 feels nimble and agile, while uneven roads unsettle the Sealion 7. At motorway speeds, the BMW remains very quiet, but the BYD suffers from wind noise around the front pillars and tyre roar in the rear. In everyday practicality, the iX3 can travel further on a charge, uses its energy more efficiently, charges faster, and can tow a heavier trailer than the Sealion 7.
