Mercedes-Benz EQB vs MG IM6

The Mercedes-Benz EQB costs £4,150 more than the MG IM6. For that premium it adds 2 more seats (7 versus 5). The MG IM6 is not just cheaper - it also offers 131 miles more WLTP range, 296 kW faster peak rapid charging and 170 litres more boot space. On EVcarsguide's combined category scores, the MG IM6 comes out ahead overall.

The MG IM6 is £4,150 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 IM6 comes out roughly £4,070 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 214 miles for the Mercedes-Benz EQB and 275 miles for the MG IM6 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The MG IM6 goes roughly 60 miles further between charging stops. A rapid charge to 80% takes around 32 minutes in the Mercedes-Benz EQB and 17 in the MG IM6, so the MG IM6 loses less time at each stop. That makes the MG IM6 the stronger long-distance car.

The Mercedes-Benz EQB is the easier car for tight UK car parks: it is 154 mm narrower than the MG IM6. In a standard 2,400 mm bay that leaves about 566 mm of total clearance for the Mercedes-Benz EQB and about 412 mm of total clearance for the MG IM6. The MG IM6 also turns in a 1.5 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 Mercedes-Benz EQB and 84% for the MG IM6. 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.
