Frequently asked questions
Which is cheaper to own over 5 years, the BYD ATTO 2 or the BYD Dolphin?
The BYD Dolphin is £655 cheaper to buy. Running costs are almost identical - about £152 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the BYD Dolphin comes out roughly £695 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the BYD ATTO 2 and BYD Dolphin like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 178 miles for the BYD ATTO 2 and 221 miles for the BYD Dolphin - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BYD Dolphin goes roughly 42 miles further between charging stops.
Which is easier to park and drive in town, the BYD ATTO 2 or the BYD Dolphin?
The BYD Dolphin is the easier car for tight UK car parks: it is 60 mm narrower than the BYD ATTO 2. In a standard 2,400 mm bay that leaves about 630 mm of total clearance for the BYD Dolphin and about 570 mm of total clearance for the BYD ATTO 2. The BYD Dolphin also turns in a 1.1 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the BYD ATTO 2 or the BYD Dolphin?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD ATTO 2 and 90% for the BYD Dolphin. 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. Both batteries carry a 8-year manufacturer warranty.
