MG S6 EV
The MG S6 EV costs £1,000 more than the Hyundai IONIQ 5. For that premium it adds 90 miles more WLTP range, 147 litres more boot space and 55 kW more power. On EVcarsguide's combined category scores, the Hyundai IONIQ 5 comes out ahead overall.
The Hyundai IONIQ 5 is £1,000 cheaper to buy. Running costs are almost identical - about £168 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Hyundai IONIQ 5 comes out roughly £1,080 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 199 miles for the Hyundai IONIQ 5 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 33 miles further between charging stops. A rapid charge to 80% takes around 18 minutes in the Hyundai IONIQ 5 and 38 in the MG S6 EV, so the Hyundai IONIQ 5 loses less time at each stop. So the MG S6 EV stops less often while the Hyundai IONIQ 5 stops for less time - pick on which you would rather do.
The two are within 22 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 510 mm of total clearance for the Hyundai IONIQ 5 and about 488 mm of total clearance for the MG S6 EV. The MG S6 EV 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 89% battery health for the Hyundai IONIQ 5 and 84% for the MG S6 EV. That gives the Hyundai IONIQ 5 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.
