Which is easier to park and drive in town, the BYD ATTO 3 or the BYD Dolphin?
The BYD Dolphin is the easier car for tight UK car parks: it is 105 mm narrower than the BYD ATTO 3.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD ATTO 3 and 90% for the BYD Dolphin.
