Summary

The BYD Dolphin is a compact family-sized hatchback and the second model from Chinese all-electric brand BYD set to arrive in UK showrooms.

The Dolphin is around the same length as the mid-sized Volkswagen ID.3, though its width is more comparable to supermini-size hatchbacks like the Peugeot e-208. This added length makes the BYD’s cabin more spacious than many of its similarly-priced rivals.

“The spacious interior is a huge highlight”, argues Parker‘s Tom Wiltshire, who also praises the Dolphin for its “interesting” cabin design and its ride quality, which is reportedly “more comfortable than many rivals.” Car adds that the BYD “comes packed full of equipment”, while Pete Tullin of Business Car asserts that the hatchback’s biggest draw will be its low price point.

That said, the Top Gear team found the car “intensely frustrating” to drive, citing slow acceleration and understeer, while other reviewers pointed out that alternatives offer better driving dynamics, more user-friendly infotainment, and higher-quality cabin materials.

As of February 2026, the BYD Dolphin holds aNew Car Expert Rating of A, with a score of 76%. It scores top marks for its excellent safety rating, low running costs and zero tailpipe emissions. However, its media reviews have been poor.

The BYD Dolphin should be a fairly cheap car to own and run, according to the limited data we currently have available.

Electrical efficiency (the EV equivalent of fuel economy on a petrol or diesel car) is good, which helps the Dolphin to achieve a decent driving range despite a relatively small battery.
