BYD Dolphin
Kia EV3
The Kia EV3 costs £2,860 more than the BYD Dolphin. For that premium it adds 96 litres more boot space. On EVcarsguide's combined category scores, the BYD Dolphin comes out ahead overall.
The BYD Dolphin is £2,860 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 £2,900 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
EVcarsguide estimates a real-world motorway range of about 221 miles for the BYD Dolphin and 193 miles for the Kia EV3 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BYD Dolphin goes roughly 28 miles further between charging stops.
The BYD Dolphin is the easier car for tight UK car parks: it is 80 mm narrower than the Kia EV3. In a standard 2,400 mm bay that leaves about 630 mm of total clearance for the BYD Dolphin and about 550 mm of total clearance for the Kia EV3. The BYD Dolphin also turns in a 1.0 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD Dolphin and 89% for the Kia EV3. That is close enough that capacity loss should not decide between them. The BYD Dolphin's LFP-type pack tolerates daily 100% charging, while the Kia EV3's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
