BMW iX3 vs Mercedes GLC Electric: Range Wins, But Does the Better Car?

The BMW iX3 and the Mercedes GLC Electric are two of the most closely matched electric SUVs in the premium midsize segment, and Electrifying has become the first channel to test them head-to-head. Both cars are dual-motor all-wheel drive, both arrive in M Sport or AMG Line trim with around seven thousand pounds of options each, and both sit at nearly the same PCP payment when you run the numbers properly. But they are built on fundamentally different philosophies. The iX3 uses a 108 kWh battery and claims up to 500 miles of WLTP range, a figure so large it reshapes how you think about daily EV ownership. The GLC Electric runs a 94 kWh usable pack and tops out at around 406 miles. On paper, that twenty percent range gap is the story. In practice, it is only the start of the disagreement.

Range is where these two diverge most sharply, and the gap matters more than the headline figures suggest. The iX3 also supports 400 kW DC charging across the entire range, which is among the fastest charging rates available in any production car currently on sale. The GLC tops out at 330 kW DC, still rapid but trailing the BMW by a meaningful margin. For buyers who prioritise long-distance capability, that combination of larger battery and faster peak charging gives the iX3 a structural advantage that no amount of interior quality can fully offset. The GLC does counter with one significant standard-fit benefit the BMW cannot match at base price: leather-style upholstery with massage seats and a panoramic glass roof are included on every GLC Electric, regardless of trim. On the BMW, the panoramic roof alone costs an extra 1,250 pounds as an option.

Inside the iX3, the story is driver-focused. The panoramic iDrive screen runs across the dashboard in a distinctive angular shape, and a large head-up display handles navigation and media without requiring the driver to look down. The steering wheel is smaller than usual, with a gap at the top that divides opinion but earns praise from those who find it comfortable. The software is entirely BMW-developed, which means it behaves consistently and connects reliably with Apple CarPlay. The main complaint from extended use: the steering wheel controls cannot skip tracks when Apple CarPlay is active, a frustration made worse by how the left-side arrows actually only change the driver display layout rather than media playback. The Mercedes interior leans differently. Its 39.1-inch curved display stretches across the dashboard and includes a passenger screen for entertainment, plus a standalone centre section capable of running ambient modes ranging from a campfire to a full aquarium animation. It is demonstrably more theatrical. The air suspension on the test car introduced a soft, rolling character in comfort mode that both testers found unsettling on country roads, though switching to sport mode firms things up at the cost of efficiency.

Bottom line: The iX3 is the more satisfying car to drive and the more capable long-distance tool. The GLC is the more opulent place to sit and, at entry level, arguably better value given what comes as standard. If range and driver engagement matter most, the BMW is the answer. If you spend more time parked in luxury than pushing country roads, the Mercedes makes a compelling case. The verdict here goes to the iX3, but only just, and the GLC that arrives without the optional air suspension might close the gap considerably.
