Mercedes-Benz GLC 300 e on test: fully loaded PHEV

E-converters have been pretty spoiled by Mercedes-Benz lately. The glorious EQS, the equally refined but slightly cheaper EQE and practical EQB family SUV have delivered high-end all-electric motoring while keeping the company’s signature interior opulence intact. The same applies to the Mercedes-Benz GLC 300 e.

This “best of both worlds” model, tested here in the AMG Line Premium Plus version, lets you choose between a petrol engine and a battery/electric motor combination. Yes, it’s a plug-in or PHEV. Ideal for those who divide their time between strolling around town and longer trips on the motorway. And when you see that the UK’s public charging network is still a bummer, that’s definitely a good thing.

The styling

The third-gen GLC isn’t radically different from previous iterations, but Merc’s delivery and execution is hugely impressive. Powerful LED headlights are new, as are the seductive curves. Buyers can choose between the equipment lines AMG Line, AMG Line Premium and AMG Line Premium Plus; ours was one of the latter, with 20-inch AMG alloys that not only looked good but offered a decent ride when you hit the road.

Some splashes of relatively understated chrome, including the clean steps on each of the rocker panels and at the rear around the dual exhaust system, work well against the Spectral Blue metallic paint finish of our test example. There are many other extras as standard, including a panoramic sunroof and an automatic tailgate. Inside you’ll find 64-color ambient lighting, which we’ve yet to grow old.

The ride

The Mercedes-Benz GLC 300 e is an easy-to-drive car that needs to be bundled up on the road with minimal effort thanks to its 9-speed automatic transmission. The wheel and tire combo really contributes a lot to the ride quality, which is comfortable but confident. Some SUVs have a tendency to navigate less than sane roads, especially when cruising in the sticks, which is where we took the car. Not so the GLC 300 e, which responds well to unpredictable surfaces and the hilly nature of overland driving.

It’s also a lot of fun, with enough power to occasionally cause excitement when you’ve got a free stretch. What makes the GLC 300 e similarly appealing is the transition from petrol engine to electric vehicle and back again, with a seamless delivery of power making it hard to tell if you’re using one or the other.

The 2.0-litre petrol engine hums decently, but is helped by the 136 hp of the electric motor. It’s still a heavy car, so doesn’t feel amazingly quick when pushing, but there’s torque on tap when you need to squeeze out of an intersection or negotiate a roundabout sharply. Motorway miles, meanwhile, are uncomplicated, fast and wonderfully quiet.

The technology

If you like comfort, the GLC 300 e won’t disappoint with excellent fully automatic seats. However, there’s plenty of tech to enjoy on the central touchscreen that dominates the center of the cabin. At 11.9 inches, it’s large but not overwhelming, giving you a balance of tech options with finesse and crisp and clear playback. The screens in the current crop of Mercedes-Benz models are some of the best money can buy.

The overall user experience is great too. Even if you’re less than enthusiastic about the proliferation of touchscreen controls in cars, the GLC 300 e offers a reliable range of options without stumbling into the annoying zone. You also get a 12.3-inch digital instrument cluster that’s equally easy on the eyes and customizable to suit your personal preferences.

The voice control of “Hey Mercedes” also works impressively efficiently and is not a dud. It gets better the more you use it, and is undeniably handy when you’re getting jittery from disruptive offspring in the background. The augmented reality support for navigation is another boon when navigating unfamiliar territory in foggy or frosty conditions.

Mercedes Benz GLC 300 e verdict

A street price of £72,210 is a sizeable chunk of cash. You get a lot for your money, though, and a big part of the fun of owning a decent Mercedes is driving one with all the toys. You will find plenty of them in the AMG Line Premium Plus variant.

The look of this car is not too ostentatious either. It just rolls down the street without you having to yell anything. Thanks to the electric drive in the city, nobody will probably notice you. That might not be enough for some Mercedes-Benz lovers who want to be seen. There’s nothing wrong with that, of course, but if you’re looking for sensible driving combined with comfort and a practical edge that makes it ideal for family life, the Mercedes Benz GLC 300 e is great.

That plug-in hybrid convenience makes life a lot easier too, and if you’ve got a wall charger you can plug it in when you get home in the evening and that’s it. And until charging is as painless as a trip to the pump, the ICE aspect continues to be fun when you’re towing your offspring to a far-flung destination.
