Kia EV3 vs MG ZS EV (2019-2021)

EVcarsguide estimates a real-world motorway range of about 193 miles for the Kia EV3 and 136 miles for the MG ZS EV - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV3 goes roughly 57 miles further between charging stops. A rapid charge to 80% takes around 29 minutes in the Kia EV3 and 40 in the MG ZS EV, so the Kia EV3 loses less time at each stop. That makes the Kia EV3 the stronger long-distance car.

The MG ZS EV is the easier car for tight UK car parks: it is 41 mm narrower than the Kia EV3. In a standard 2,400 mm bay that leaves about 591 mm of total clearance for the MG ZS EV and about 550 mm of total clearance for the Kia EV3. The Kia EV3 also turns in a 0.8 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 EV3 and 84% for the MG ZS EV. That gives the Kia EV3 a modest edge in retained real-world range. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation. The Kia EV3 has the longer battery warranty at 8 years, versus 7 for the MG ZS EV.
