The Kia EV4 goes roughly 44 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 25-31 minutes.

The two are within 24 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 540 mm of total clearance for the Kia EV4. The MG MG4 EV also turns in a 0.4 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Kia EV4 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 EV4's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
