Frequently asked questions
Is the Audi Q4 e-tron worth the extra £14,765 over the MG S5 EV?
The Audi Q4 e-tron costs £14,765 more than the MG S5 EV. For that premium it adds 67 litres more boot space. The MG S5 EV is not just cheaper - it also offers a 1.8s quicker 0-62mph time. On EVcarsguide's combined category scores, the Audi Q4 e-tron comes out ahead overall.
Which is cheaper to own over 5 years, the Audi Q4 e-tron or the MG S5 EV?
The MG S5 EV is £14,765 cheaper to buy. Running costs are almost identical - about £160 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 £14,725 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Audi Q4 e-tron and MG S5 EV like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 229 miles for the Audi Q4 e-tron and 208 miles for the MG S5 EV - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi Q4 e-tron goes roughly 21 miles further between charging stops.
Which is easier to park and drive in town, the Audi Q4 e-tron or the MG S5 EV?
The two are within 16 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 535 mm of total clearance for the Audi Q4 e-tron. The Audi Q4 e-tron also turns in a 0.3 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the Audi Q4 e-tron or the MG S5 EV?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q4 e-tron and 84% for the MG S5 EV. 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.
