Kia EV6 vs MG IM6

The MG IM6 costs £2,360 more than the Kia EV6. For that premium it adds 27 miles more WLTP range, 138 kW faster peak rapid charging and 175 litres more boot space. On EVcarsguide's combined category scores, the Kia EV6 comes out ahead overall.

The Kia EV6 is £2,360 cheaper to buy. The Kia EV6 is cheaper to charge, roughly £160 a year versus £200 for the MG IM6, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Kia EV6 comes out roughly £2,560 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 301 miles for the Kia EV6 and 275 miles for the MG IM6 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV6 goes roughly 26 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 17-18 minutes.

The Kia EV6 is the easier car for tight UK car parks: it is 98 mm narrower than the MG IM6. In a standard 2,400 mm bay that leaves about 510 mm of total clearance for the Kia EV6 and about 412 mm of total clearance for the MG IM6. The MG IM6 also turns in a 1.4 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 EV6 and 84% for the MG IM6. That gives the Kia EV6 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.
