MG IM5 vs Polestar 2 (2020-2023)

EVcarsguide estimates a real-world motorway range of about 217 miles for the MG IM5 and 253 miles for the Polestar 2 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Polestar 2 goes roughly 35 miles further between charging stops. A rapid charge to 80% takes around 65 minutes in the MG IM5 and 28 in the Polestar 2, so the Polestar 2 loses less time at each stop. That makes the Polestar 2 the stronger long-distance car.

The Polestar 2 is the easier car for tight UK car parks: it is 101 mm narrower than the MG IM5. In a standard 2,400 mm bay that leaves about 541 mm of total clearance for the Polestar 2 and about 440 mm of total clearance for the MG IM5. The MG IM5 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 MG IM5 and 84% for the Polestar 2. That gives the MG IM5 a modest edge in retained real-world range. The MG IM5's LFP-type pack tolerates daily 100% charging, while the Polestar 2's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
