The BYD Sealion 5 DM-i is a clear signal of how aggressively the brand intends to compete in the UK’s most hotly contested segment. By offering a well-equipped plug-in hybrid SUV from under £30,000, BYD has effectively removed the price premium that usually accompanies electrification. The headline electric-only range of up to 53 miles is particularly significant, as it allows many owners to complete day-to-day driving without engaging the petrol engine at all, while still retaining the flexibility of long-distance capability.
