Background
Some car makers (Jaguar and Alfa Romeo for instance) think coupe versions of mid-sized SUVs are unnecessary. The German posh brands though, all think this kind of variant essential, a trend started in 2014 with the BMW X4, then followed in 2016 by the first generation Mercedes GLC Coupe (and subsequently by the Audi Q5 Sportback). In 2022, Mercedes launched the standard SUV version of its second generation GLC. So it was natural that we would then also get a second generation GLC Coupe. That model, codenamed 'C254', is what we look at here.
Like the ordinary GLC, it's entirely C-Class-based and is built alongside that model at Mercedes' German factory in Bremen. The brand says it's developed this GLC Coupe to be a little more dynamic than its partner model. Is that what's being served up here? Let's take a look.
Driving Experience
Mercedes says it's made the steering of this second generation GLC Coupe a little sharper than the SUV version to give this sporty-looking variant a small dynamic edge. But the difference is slight. The engine range is the same as that of the ordinary model, which means it's fully electrified. As before, the line-up will mainly sell in 2.0-litre petrol and diesel forms, both units now embellished with mild hybrid tech. The GLC 220 d diesel has 197hp; the GLC 300 diesel has 269hp; and the GLC 300 petrol has 258hp.
Over the last few years, this model line has been increasingly popular in Plug-in Hybrid form. The GLC 300 e model uses the 2.0-litre petrol engine and develops 308hp. Its 31.2kWh battery offers an EV range of up to 77 miles. The GLC 43 and GLC 63 AMG performance variants will also get 2.0-litre four cylinder powerplants - petrol ones of course; a mild hybrid for the 43 and a 671hp PHEV unit for the 63. As before, all models across the line-up feature 4MATIC all wheel drive and a 9-speed automatic gearbox. Optional is AIRMATIC air suspension and this MK2 model further adds the option of Rear-Axle Steering, the latter vastly improving the car's turning circle (by 90cm) and giving extra stability through the bends.
Design and Build
If you want a GLC, then it's probable that this is what you think it should look like. As with the previous model, this second generation GLC Coupe differs from the conventional GLC SUV with a sloping rear roof line flowing into a liftback-style tailgate. It's a slightly more upright thing now though, standing 55mm higher than the original. It's also 31mm longer (4,763mm long), with tauter surfacing, more pronounced feature lines and bigger wheel sizes. The contoured bonnet flows into a larger grille flanked by shapelier LED headlights. The tail lamps are redesigned too and there's a chromed lower valance with an integrated diffuser incorporating twin tailpipes.
Inside at the front, it's of course the same as the ordinary MK2 GLC, which means higher quality materials, a more up-market dashboard, re-styled vents, a smarter steering wheel, a 12.3-inch instrument display and an 11.9-inch portrait-orientated centre screen. The extra roof height and 15mm of extra wheelbase length help the rear cabin. The bench slides back and forth too, which aids cargo flexibility. And out back, the boot is 45-litres bigger at 545-litres with the conventional models (55-litres less than the GLC SUV); it's 390-litres for the GLC Coupe PHEV. Fold the rear bench and there's 1,490-litres with a conventionally-engined GLC Coupe - or 1,335-litres if it's a PHEV.
Market and Model
Expect a big premium over the standard SUV body shape - around £5,500. Which means that prices for this second generation GLC Coupe start at around £60,000 for the base GLC 220 d AMG Line, rising to just over £80,000 for the top mainstream variant, the plug-in hybrid GLC 300 e AMG Line Premium Plus. Across the range, expect the same 'AMG Line', 'AMG Line Premium' and 'AMG Line Premium Plus' trim levels. The top performance AMG models start from around £79,000 for the 43 mild hybrid version, with prices rising to a startinbg point of around £94,000 for the 63 S E Performance PHEV 671hp variant.
At least the standard equipment is generous, with things like smartphone integration, wireless charging and heated front seats standard across the range. Many GLC customers will want to look at the optional 'DIGITAL LIGHT' headlamps. These project in front of the car onto the road surface when driving at night, with things like guidance lines, symbols and animation, plus the system's intelligent technology highlights pedestrians that you might come across with a spotlight function. If you've extra to spend, you might also want to look at the 'Parking Package' with its 360-degree camera.
Quite a few owners will want to add on a tow bar - and will like the new 'Towing Route Planner' that's been added into the navigation system. Using this, routes can be planned in the central display that are suitable for driving with a trailer, taking into account things like passage width and passage heights. And there's an enhanced 'Trailer Manoeuvring Assistant' system that makes manoeuvring with a trailer easier, more comfortable and safer.
Cost of Ownership
Given the huge proportion of business sales accounted for by the GLC Coupe, Mercedes couldn't afford to return anything but a stellar set of efficiency figures with this MK2 model - and that's what we've got from the fully electrified engine range. Most customers will be choosing either the mild hybrid diesel GLC 220d, which returns up to 54.3mpg on the combined cycle: or the mild hybrid petrol GLC 300, which returns up to 38.7mpg on the combined cycle.
If you want to do better, you'll need the Plug-in Hybrid version. The single petrol PHEV variant, the GLC 300e, is rated at 470.8mpg. In reality, expect the kind of regular consumption figures you'd get from a decent diesel. The PHEV has a bigger 31.2kWh battery this time round, which gives this petrol version an EV driving range of up to 77 miles. There's also a four-cylinder PHEV powertrain for the GLC Coupe 63 S E Perfpormance AMG model - but with only a tiny EV range.
What else? Well you get a comprehensive three year warranty that has no mileage restriction (rival BMW and Audi warranties restrict you to 60,000 miles). And this package is built upon by Mercedes' Mobilo scheme which delivers breakdown cover for up to thirty years, as long as you continue to have your car serviced at a Mercedes main dealer. And it's worth knowing that your maintenance outlay can be kept a little in check by going for the optional Service Care package that takes care of routine maintenance, spreading the cost of regular servicing.
