Mercedes-Benz EQB vs MG S5 EV

The Mercedes-Benz EQB costs £20,650 more than the MG S5 EV. On the headline specs that premium buys little measurable advantage - the two are closely matched on range, charging and space. The MG S5 EV is not just cheaper - it also offers 41 miles more WLTP range, 39 kW faster peak rapid charging and a 1.7s quicker 0-62mph time. On EVcarsguide's combined category scores, the MG S5 EV comes out ahead overall.

The MG S5 EV is £20,650 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 MG S5 EV comes out roughly £20,730 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 208 miles for the MG S5 EV - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. Both rapid-charge to 80% in a similar time, around 28-32 minutes.

The two are within 15 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 566 mm of total clearance for the Mercedes-Benz EQB and about 551 mm of total clearance for the MG S5 EV. The MG S5 EV also turns in a 1.2 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 S5 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.
