Nissan Micra
EVcarsguide estimates a real-world motorway range of about 171 miles for the firefly firefly and 137 miles for the Nissan Micra - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The firefly firefly goes roughly 34 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 25-30 minutes.
The two are within 1 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 620 mm of total clearance for the Nissan Micra and about 619 mm of total clearance for the firefly firefly. The firefly firefly also turns in a 0.8 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the firefly firefly and 90% for the Nissan Micra. That gives the Nissan Micra a modest edge in retained real-world range. The Nissan Micra's LFP-type pack tolerates daily 100% charging, while the firefly firefly's NMC-type pack lasts longest kept to about 80% for everyday use.
