MG S6 EV vs Subaru Solterra

The Subaru Solterra costs £14,510 more than the MG S6 EV. For that premium it adds a 2.3s quicker 0-62mph time. The MG S6 EV is not just cheaper - it also offers 40 miles more WLTP range and 222 litres more boot space. On EVcarsguide's combined category scores, the Subaru Solterra comes out ahead overall.

The MG S6 EV is £14,510 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 S6 EV comes out roughly £14,430 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 232 miles for the MG S6 EV and 241 miles for the Subaru Solterra - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. A rapid charge to 80% takes around 38 minutes in the MG S6 EV and 20 in the Subaru Solterra, so the Subaru Solterra loses less time at each stop.

The Subaru Solterra is the easier car for tight UK car parks: it is 52 mm narrower than the MG S6 EV. In a standard 2,400 mm bay that leaves about 540 mm of total clearance for the Subaru Solterra and about 488 mm of total clearance for the MG S6 EV.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the MG S6 EV and 84% for the Subaru Solterra. 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.
