The Mercedes GLC electric arrives wearing a £60,000 starting price and a 393-mile WLTP range claim. On carwow's 40-minute test route, it averaged 331 watt-hours per mile and returned a real-world range figure of 282 miles from the 94 kWh battery. That gap of 111 miles is not evidence of a broken car. It is evidence of a test cycle that does not represent the road. The Range Topper version tested here sits at £73,000 before options, and buyers at that level are entitled to expect the headline figure to land within reasonable reach of reality. Two electric motors, four-wheel drive, and 490 horsepower are harder to argue with: the 0 to 60 mph run came in at 4.06 seconds, quicker than Mercedes' own stated 4.3-second claim.
The GLC competes directly with the BMW iX3 and the Audi Q6 e-tron, both of which carry similar gaps between their official range figures and typical real-world results. The BMW iX3, with a 77 kWh net battery and a WLTP claim around 375 miles, generally tests in the 250 to 270 mile range on mixed routes, making the GLC's 282-mile result representative of the premium electric SUV segment rather than exceptional to it. Where the GLC has a genuine advantage is in storage: the boot measures 570 litres, larger than the iX3's 510 litres, and the front compartment under the bonnet adds over 100 litres more, which the reviewer notes exceeds the Tesla Model Y's equivalent storage. For buyers making long-distance plans around an official range figure, the adjustment downward by roughly a quarter is a conversation worth having before collection day.
The interior tells two stories. The 39-inch hyperscreen that spans nearly the full dashboard is genuinely striking, and the ambient lighting system around the panoramic roof changes colour on demand and reads as an expensive touch rather than a gimmick. The surround-view camera system detects parking spaces ahead of the vehicle before the driver reaches them, which worked cleanly during testing. But the climate control system runs entirely through the touchscreen with no physical shortcuts, a frustration in a car at this price point, and the air vents near the centre console use plastic that feels inconsistent with the rest of the cabin. The stalks and handle area around the door cards earned similar criticism. These are not catastrophic faults, but they register more sharply when the sticker reads £73,000. On the road, the optional Refinement Package at £2,500 adds active air suspension and rear-axle steering, transforming a 2.7-tonne SUV into something that corners with composure and handles tighter gaps with a turning circle the reviewer compared to a compact saloon. The brake pedal is notably linear, with none of the grabby initial bite common in large electric SUVs. In town and on country roads, the GLC is easy to trust and genuinely pleasant to drive.
Bottom line: The GLC electric earns its position as a premium SUV through driving dynamics, build quality, and engineering. It does not earn the 393-mile range claim. Plan around 280 miles and the car becomes straightforward to recommend. Plan around the brochure figure and you will spend a lot of time at public chargers you did not expect. The cheap plastic around the air vents and the absence of physical climate controls are the kind of details Mercedes should have caught before sign-off on a car this expensive.
