VW ID.3 vs MG4 EV

The MG MG4 EV is £865 cheaper to buy. The VW ID.3 is cheaper to charge, roughly £144 a year versus £192 for the MG MG4 EV, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the MG MG4 EV comes out roughly £625 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 201 miles for the VW ID.3 and 181 miles for the MG MG4 EV - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The VW ID.3 goes roughly 19 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 25-25 minutes.

The two are within 27 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 591 mm of total clearance for the VW ID.3 and about 564 mm of total clearance for the MG MG4 EV. The VW ID.3 also turns in a 0.3 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 87% battery health for the VW ID.3 and 90% for the MG MG4 EV. That gives the MG MG4 EV a modest edge in retained real-world range. The MG MG4 EV's LFP-type pack tolerates daily 100% charging, while the VW ID.3's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
