MG4 EV
The MG MG4 EV is £855 cheaper to buy. The BYD ATTO 2 is cheaper to charge, roughly £160 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 £695 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 178 miles for the BYD ATTO 2 and 181 miles for the MG MG4 EV - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV.
The two are within 6 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 570 mm of total clearance for the BYD ATTO 2 and about 564 mm of total clearance for the MG MG4 EV.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD ATTO 2 and 90% for the MG MG4 EV. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day. Both batteries carry a 8-year manufacturer warranty.
