The BYD ATTO 2 is £8,145 cheaper to buy. Running costs are almost identical - about £152 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the BYD ATTO 2 comes out roughly £8,105 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 290 miles for the Mazda 6e - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mazda 6e goes roughly 112 miles further between charging stops.

The BYD ATTO 2 is the easier car for tight UK car parks: it is 60 mm narrower than the Mazda 6e. In a standard 2,400 mm bay that leaves about 570 mm of total clearance for the BYD ATTO 2 and about 510 mm of total clearance for the Mazda 6e. The BYD ATTO 2 also turns in a 1.1 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD ATTO 2 and 90% for the Mazda 6e. 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.
