The MG S6 EV costs £1,000 more than the VW ID.4. For that premium it adds 141 litres more boot space. The VW ID.4 is not just cheaper - it also offers 30 kW more power and a 2.5s quicker 0-62mph time. On EVcarsguide's combined category scores, the VW ID.4 comes out ahead overall.
The VW ID.4 is £1,000 cheaper to buy. The VW ID.4 is cheaper to charge, roughly £152 a year versus £184 for the MG S6 EV, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the VW ID.4 comes out roughly £1,160 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 293 miles for the VW ID.4 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The VW ID.4 goes roughly 62 miles further between charging stops. A rapid charge to 80% takes around 38 minutes in the MG S6 EV and 29 in the VW ID.4, so the VW ID.4 loses less time at each stop. That makes the VW ID.4 the stronger long-distance car.
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.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the MG S6 EV and 84% for the VW ID.4. 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.
