Frequently asked questions
Is the VW ID.4 worth the extra £2,280 over the MG S6 EV?
The VW ID.4 costs £2,280 more than the MG S6 EV. On the headline specs that premium buys little measurable advantage - the two are closely matched on range, charging and space.

The MG S6 EV is £2,280 cheaper to buy. Running costs are almost identical - about £160 a year either way, at 8,000 miles on an off-peak home tariff.

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 185 miles for the VW ID.4 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The MG S6 EV goes roughly 47 miles further between charging stops.
Which is easier to park and drive in town, the MG S6 EV or the VW ID.4?
The VW ID.4 is the easier car for tight UK car parks: it is 60 mm narrower than the MG S6 EV. In a standard 2,400 mm bay that leaves about 548 mm of total clearance for the VW ID.4 and about 488 mm of total clearance for the MG S6 EV. The VW ID.4 also turns in a 0.9 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the MG S6 EV or the VW ID.4?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the MG S6 EV and 87% for the VW ID.4. That gives the VW ID.4 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.
