Kia EV3 vs MG4 EV (2022-2025)

The Kia EV3 costs £7,060 more than the MG MG4 EV. For that premium it adds 53 miles more WLTP range, 97 litres more boot space and lower energy use, 149 versus 170 Wh/km. On EVcarsguide's combined category scores, the Kia EV3 comes out ahead overall.

The MG MG4 EV is £7,060 cheaper to buy. Running costs are almost identical - about £160 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the MG MG4 EV comes out roughly £6,940 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 193 miles for the Kia EV3 and 155 miles for the MG MG4 EV - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV3 goes roughly 38 miles further between charging stops. A rapid charge to 80% takes around 29 minutes in the Kia EV3 and 39 in the MG MG4 EV, so the Kia EV3 loses less time at each stop. That makes the Kia EV3 the stronger long-distance car.

The two are within 14 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 564 mm of total clearance for the MG MG4 EV and about 550 mm of total clearance for the Kia EV3.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Kia EV3 and 90% for the MG MG4 EV. That is close enough that capacity loss should not decide between them. The MG MG4 EV'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. The Kia EV3 has the longer battery warranty at 8 years, versus 7 for the MG MG4 EV.
