MG S5 EV vs Peugeot e-408

The Peugeot e-408 costs £2,770 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 a 1.3s quicker 0-62mph time. On EVcarsguide's combined category scores, the MG S5 EV comes out ahead overall.

The MG S5 EV is £2,770 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 £2,810 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 208 miles for the MG S5 EV and 177 miles for the Peugeot e-408 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The MG S5 EV goes roughly 30 miles further between charging stops.

The two are within 10 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 551 mm of total clearance for the MG S5 EV and about 541 mm of total clearance for the Peugeot e-408. The MG S5 EV also turns in a 0.7 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 S5 EV and 84% for the Peugeot e-408. 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.
