The BYD Sealion 5 comes powered by a 1.5L four-cylinder engine that serves as a high-efficiency generator that recharges a 12.96 kWh lithium-iron phosphate battery pack. On a full charge, BYD claims the Sealion 5 can travel up to 71 km based on the NEDC cycle on battery power alone. But thanks to the 1.5L engine, the crossover is rated to have a total system range of over 1,000 km.
