Frequently asked questions
What are the BYD Dolphin and Leapmotor B05 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 221 miles for the BYD Dolphin and 197 miles for the Leapmotor B05 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BYD Dolphin goes roughly 24 miles further between charging stops.
Which is easier to park and drive in town, the BYD Dolphin or the Leapmotor B05?
The BYD Dolphin is the easier car for tight UK car parks: it is 40 mm narrower than the Leapmotor B05. In a standard 2,400 mm bay that leaves about 630 mm of total clearance for the BYD Dolphin and about 590 mm of total clearance for the Leapmotor B05. The BYD Dolphin also turns in a 0.9 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the BYD Dolphin or the Leapmotor B05?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD Dolphin and 90% for the Leapmotor B05. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day.
