Kia EV6 vs MG IM5

The Kia EV6 costs £6,185 more than the MG IM5. For that premium it adds 57 miles more WLTP range and 105 kW faster peak rapid charging. The MG IM5 is not just cheaper - it also offers 49 kW more power and a 0.9s quicker 0-62mph time. On EVcarsguide's combined category scores, the Kia EV6 comes out ahead overall.

The MG IM5 is £6,185 cheaper to buy. The Kia EV6 is cheaper to charge, roughly £160 a year versus £192 for the MG IM5, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the MG IM5 comes out roughly £6,025 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 217 miles for the MG IM5 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV6 goes roughly 83 miles further between charging stops. A rapid charge to 80% takes around 18 minutes in the Kia EV6 and 65 in the MG IM5, so the Kia EV6 loses less time at each stop. That makes the Kia EV6 the stronger long-distance car.

The Kia EV6 is the easier car for tight UK car parks: it is 70 mm narrower than the MG IM5. In a standard 2,400 mm bay that leaves about 510 mm of total clearance for the Kia EV6 and about 440 mm of total clearance for the MG IM5. The MG IM5 also turns in a 1.6 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 90% for the MG IM5. That is close enough that capacity loss should not decide between them. The MG IM5's LFP-type pack tolerates daily 100% charging, while the Kia EV6's NMC-type pack lasts longest kept to about 80% for everyday use.
