EVcarsguide estimates a real-world motorway range of about 178 miles for the BYD ATTO 2 and 161 miles for the Citroën ë-C4 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BYD ATTO 2 goes roughly 17 miles further between charging stops.

The Citroën ë-C4 is the easier car for tight UK car parks: it is 30 mm narrower than the BYD ATTO 2. In a standard 2,400 mm bay that leaves about 600 mm of total clearance for the Citroën ë-C4 and about 570 mm of total clearance for the BYD ATTO 2. The BYD ATTO 2 also turns in a 0.4 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 84% for the Citroën ë-C4.

The BYD ATTO 2's LFP-type pack tolerates daily 100% charging, while the Citroën ë-C4's NMC-type pack lasts longest kept to about 80% for everyday use.
