Frequently asked questions
Which is cheaper to own over 5 years, the MG S6 EV or the Vauxhall Grandland?
The Vauxhall Grandland is £640 cheaper to buy. Running costs are almost identical - about £184 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Vauxhall Grandland comes out roughly £600 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the MG S6 EV and Vauxhall Grandland like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 232 miles for the MG S6 EV and 220 miles for the Vauxhall Grandland - 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 30 in the Vauxhall Grandland, so the Vauxhall Grandland loses less time at each stop.
Which is easier to park and drive in town, the MG S6 EV or the Vauxhall Grandland?
The MG S6 EV is the easier car for tight UK car parks: it is 196 mm narrower than the Vauxhall Grandland. In a standard 2,400 mm bay that leaves about 488 mm of total clearance for the MG S6 EV and about 292 mm of total clearance for the Vauxhall Grandland.
Which battery will hold up better as a used buy, the MG S6 EV or the Vauxhall Grandland?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the MG S6 EV and 84% for the Vauxhall Grandland. 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.
