Summary
The Mercedes-Benz GLC is a medium-sized premium SUV/crossover, which sits between the smaller GLA and larger GLE in the Mercedes-Benz SUV family. This is the second-generation model, which went on sale in the final months of 2022.
Fitted with the latest infotainment tech and combustion-powered drivetrains that Mercedes-Benz has to offer, the latest GLC is described by several reviewers as an evolution of the outgoing model.
Carbuyer‘s Tom Jervis claims that it has “one of the most high-tech cabins in the class”, while concluding that “the already-spacious GLC is even more practical than before”.
The Top Gear team praises the SUV for its “more elegant and sophisticated” exterior styling, while What Car? is more impressed by the GLC’s range of engines – particularly the plug-in hybrid variants that offer a very competitive electric driving range.
While the GLC is certainly efficient, on-the-road excitement is another matter. “Flat-out acceleration is hardly exciting”, says What Car?, and while the SUV is an accomplished motorway cruiser, “it doesn’t feel all that settled at slow speeds.”
Focused on the build quality, Honest John adds that the interior, while classy, does feature some cheap materials in places, despite its rather expensive price tag.
As of October 2023, the second-generation Mercedes-Benz GLC holds an Expert Rating of 70%, based on 21 reviews published by the UK motoring media. This is still a new model, so this rating may still fluctuate up or down by a few points in coming months.

Auto Express
Model reviewed: Coupe 300 (2023)
Score: 6 / 10
“A little practicality is lost but otherwise, the Mercedes-Benz GLC Coupe has all of the impressive attributes seen on the new GLC with a premium interior, refinement and a comfy ride. It’s extremely difficult to recommend the Coupe over the SUV model based on these qualities, however, and that’s before you get to the price tag.” (Alastair Crooks)

Model reviewed: 2.0-litre diesel automatic GLC 200d 4Matic
Score: 8 / 10
“The new Mercedes-Benz GLC appears to have improved in every area over the old model, but unfortunately you’re likely to incur a hefty price increase for this newfound ability. The GLC has class-leading technology on board and feels more premium, but perhaps most surprisingly, it drives as well as any of its rivals.”

Model reviewed: 2.0-litre diesel automatic GLC 300 de 4Matic
Score: 9 / 10
“The most expensive version of the Mercedes-Benz GLC could be the best. The plug-in hybrid system is one of the best around, however it’s a shame the impressive technology, refinement and efficiency has caused the weight to shoot up. It’s an improvement on the old car in all key areas, so the GLC’s global success looks set to continue.” (Alastair Crooks)

Model reviewed: 2.0-litre petrol-electric plug-in hybrid 300 e AMG Line
Score: 9 / 10
“With this 300 e model, Mercedes has shown it’s capable of developing class-leading technology in the plug-in hybrid sector, while retaining that all-important focus on refinement. Plenty of rivals are more fun to drive, however, and with the firm pushing more towards the premium end of the market, the GLC’s pricing could be a tough pill to swallow.” (Alastair Crooks)

Model reviewed: 2.0-litre petrol automatic GLE Coupe 300 AMG Line
Score: 7 / 10
“As is often the case when SUVs become coupés, the Mercedes-Benz GLC Coupé demands a premium over the standard car, adding almost £7,000 to the price. When you factor in the ride and the gearbox, that makes it quite hard to justify spending the extra over the standard car.” (Dan Jones)

Model reviewed: 2.0-litre diesel automatic GLC 220d 4Matic
Score: 9 / 10
“The Mercedes-Benz GLC costs from around £50,000. Pricey? Yes. But if you can afford it, it offers a broad range of qualities that few if any rivals can match, particularly in 220d guise.”

Car
Model reviewed: GLC Coupé range
Score: 6 / 10
“We’d recommend you avoid the Mercedes GLC Coupe. It doesn’t drive any better than the standard car, which means it’s of little interest to petrolheads, and the practicality sacrifices it makes dampen its appeal for family buyers. If you want a mid-sized Mercedes SUV, just stick with the standard GLC SUV. But if you’re hell-bent on owning a mid-sized coupe SUV, you’d be better served by the BMW X4 or Audi Q5 Sportback.” (Luke Wilkinson)

“It weighs a tonne or two, costs an arm and a leg, and is only partly electrified. But the new Mercedes-Benz GLC is roomy and nicely appointed, its ride is best in class and the driving pleasure is more C-class inspiring than SUV-like ponderous. And it is a *proper* Mercedes – evolutionary rather than ground-breaking, yet competent through and through.” (Georg Kacher)

“The Mercedes-Benz GLC Coupe is a stylish alternative to the standard GLC that’s just as nice to travel in, but alternatives have more spacious cabins, bigger boots and better infotainment.”

Score: 8 / 10
“The Mercedes-Benz GLC sits slap bang in the middle of the brand’s SUV lineup, and the new second-generation car should be a popular one. Classy, clever and with some impressive hybrid options, it’s only a shame that progress doesn’t come cheap.”

Model reviewed: Range overview
Score: 8 / 10
“The new Mercedes-Benz GLC will no doubt continue the model’s success. Majoring on space, technology and refinement, it also offers supreme efficiency from its long-range plug-in hybrid options. It doesn’t stand head-and-shoulders above rivals on the road, though, and there’s been quite a price jump over the old model.”

“There’s certainly plenty to recommend the Mercedes-Benz GLC, with the impressive electric-only range of the 300e beating rivals comfortably. We suspect plenty will love the techno-flash interior design and space for passengers is decent, too. However, while it’s comfortable on the motorway, there are better-driving SUVs in the class and bigger ones, too.” (Alan Taylor-Jones)

“Image is everything when it comes to premium mid-sized SUVs and on that basis, this second-generation Mercedes-Benz GLC is a very desirable package. As an all-rounder, the GLC remains a tempting package. A segment benchmark? You’d have to say so.” (Jonathan Crouch)

Score: 6 / 10
“For the company-car driver with off-street parking and a home wallbox, the favourable tax treatment of the Mercedes-Benz GLC 300 e and its potential fuel savings should offset the high price, though not by much. I quite like the GLC but, despite the technical virtuosity shown in this plug-in model, I’d prefer a diesel-engined version.” (Andrew English)

“From the outside, this expensive family SUV looks just another affectation of the wealthy, but underneath it’s quite a piece of work, with (in PHEV form) a long range in electric mode, decent economy, tidy ride and handling (at least in the cars we drove) and a comfortable and well-finished interior.” (Andrew English)

“The GLC is a great all-rounder that will slot painlessly into the lives of its buyers and provides a useful entry point into electric motoring. Of course, we’ll always say you’d be better off getting a nice C-Class estate,”

“As premium SUVs go, the GLC offers a good range of engines and a pleasant interior with plenty of space for occupants. It’s the plug-in hybrid versions with their huge electric range that make it stand out above rivals, though, especially for company car drivers.”

The Mercedes-Benz GLC is an expensive car to run, according to numbers provided exclusively to The Car Expert by our data partner, Clear Vehicle Data.
Fuel consumption is disappointingly poor for petrol models, and only average for diesels. The plug-in hybrid stats look good on paper, but this is largely a function of misleading EU/UK government lab tests that make every plug-in hybrid look amazing. There are no real-world situations where you’re going to get 381 miles out of a single gallon (4.5 litres) of fuel and a bit of electricity.
Battery range on the plug-in hybrid is quite good, with an official range of 56 miles – although this depends on which model you choose. If you are able to charge the GLC every day, you may well be able to do all of your day-to-day driving purely on electrical power. On longer trips, you’ll still probably run out of charge fairly quickly.
Insurance and scheduled servicing costs for the GLC are likely to be high, especially compared to similarly-sized cars from other brands.
