MG IM6 vs MG S6 EV

The MG IM6 costs £10,000 more than the MG S6 EV. For that premium it adds 60 miles more WLTP range, 246 kW faster peak rapid charging and 120 kW more power. The MG S6 EV is not just cheaper - it also offers lower energy use, 166 versus 182 Wh/km. On EVcarsguide's combined category scores, the MG S6 EV comes out ahead overall.

The MG S6 EV is £10,000 cheaper to buy. Running costs are almost identical - about £184 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the MG S6 EV comes out roughly £10,080 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 275 miles for the MG IM6 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 IM6 goes roughly 43 miles further between charging stops. A rapid charge to 80% takes around 17 minutes in the MG IM6 and 38 in the MG S6 EV, so the MG IM6 loses less time at each stop. That makes the MG IM6 the stronger long-distance car.

The MG S6 EV is the easier car for tight UK car parks: it is 76 mm narrower than the MG IM6. In a standard 2,400 mm bay that leaves about 488 mm of total clearance for the MG S6 EV and about 412 mm of total clearance for the MG IM6. The MG IM6 also turns in a 0.9 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the MG IM6 and 84% for the MG S6 EV. That is close enough that capacity loss should not decide between them. 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.
