Cupra Raval
firefly
EVcarsguide estimates a real-world motorway range of about 139 miles for the Cupra Raval and 171 miles for the firefly firefly - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The firefly firefly goes roughly 32 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 23-25 minutes.
The two are within 3 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 619 mm of total clearance for the firefly firefly and about 616 mm of total clearance for the Cupra Raval. The firefly firefly also turns in a 1.5 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 Cupra Raval and 84% for the firefly firefly. That gives the Cupra Raval a modest edge in retained real-world range. The Cupra Raval'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.
