BYD ATTO 3
Hyundai IONIQ 5
The BYD ATTO 3 is £5 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 two land within £45 of each other - effectively the same to own. 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 213 miles for the BYD ATTO 3 and 199 miles for the Hyundai IONIQ 5 - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. A rapid charge to 80% takes around 35 minutes in the BYD ATTO 3 and 18 in the Hyundai IONIQ 5, so the Hyundai IONIQ 5 loses less time at each stop.
The two are within 15 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 525 mm of total clearance for the BYD ATTO 3 and about 510 mm of total clearance for the Hyundai IONIQ 5. The BYD ATTO 3 also turns in a 1.6 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 92% battery health for the BYD ATTO 3 and 89% for the Hyundai IONIQ 5. That gives the BYD ATTO 3 a modest edge in retained real-world range. The BYD ATTO 3's LFP-type pack tolerates daily 100% charging, while the Hyundai IONIQ 5's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
