EVcarsguide estimates a real-world motorway range of about 275 miles for the MG IM6 and 321 miles for the Polestar 4 Coupé - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Polestar 4 Coupé goes roughly 47 miles further between charging stops.

The two are within 20 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 412 mm of total clearance for the MG IM6 and about 392 mm of total clearance for the Polestar 4 Coupé. The MG IM6 also turns in a 1.5 m tighter circle, which helps with U-turns and multi-storey ramps.
