Kia EV3 vs MG S6 EV

The MG S6 EV costs £4,940 more than the Kia EV3. For that premium it adds 58 miles more WLTP range, 214 litres more boot space and 30 kW more power. The Kia EV3 is not just cheaper - it also offers a 1.7s quicker 0-62mph time and lower energy use, 149 versus 166 Wh/km. On EVcarsguide's combined category scores, the Kia EV3 comes out ahead overall.

The Kia EV3 is £4,940 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 Kia EV3 comes out roughly £5,060 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 232 miles for the MG S6 EV - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The MG S6 EV goes roughly 39 miles further between charging stops. A rapid charge to 80% takes around 29 minutes in the Kia EV3 and 38 in the MG S6 EV, so the Kia EV3 loses less time at each stop. So the MG S6 EV stops less often while the Kia EV3 stops for less time - pick on which you would rather do.

The Kia EV3 is the easier car for tight UK car parks: it is 62 mm narrower than the MG S6 EV. In a standard 2,400 mm bay that leaves about 550 mm of total clearance for the Kia EV3 and about 488 mm of total clearance for the MG S6 EV. The Kia EV3 also turns in a 0.7 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 S6 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. Both batteries carry a 8-year manufacturer warranty.
