Mercedes-Benz GLC (2023) Launch Review
A new Mercedes-Benz GLC has landed in South Africa to renew the Three-pointed Star’s quest for supremacy in the Executive SUV segment. Is it premium enough to justify its hefty price tag? We drove the new model at its local launch in Cape Town.
What’s new with the GLC?
If you ever needed more proof that SUVs are the vehicles of choice in the premium sector, here it is: the GLC recently superseded the long-serving C-Class as Mercedes-Benz’s best-selling model globally.
This is the 2nd-generation GLC, replete with a new chassis, a fresh design as well as a tech upgrade. It’s based on the underpinnings of the W206-generation C-Class and features a very similar interior to the sedan, but has some interesting off-road tech for an SUV that’s likely to spend little time on gravel roads.
Most of the new techy additions to the GLC are assigned to the options list though. Features such as the air suspension and rear-wheel steering are available as part of the Engineering Package, for example.
Speaking of packages, ‘Benz has made it easier for buyers to sift through the options list by bundling features that are often selected together. While that means you can’t spec your GLC to your exact preference, it takes a lot of the hassle out of selecting from hundreds of items on the configurator.
All the powertrains in the range make use of mild-hybrid tech (including a 48V electrical architecture) in order to minimise fuel consumption and support the internal combustion engine (ICE) when required.
What’s the interior of the GLC like?
Effectively a clone of the C-Class’ interior, the front of the GLC’s cabin is decked out in hi-resolution screens. The centre touchscreen houses all vehicle controls, plus media, navigation and system settings in its menu. There’s a lot to work through – it’s initially overwhelming – but if you get stuck, you can always use the voice prompt “Hey Mercedes” and ask the MBUX to access functions on your behalf.
The instrument cluster has multiple themes and designs to choose from and is easily navigable through the multifunction steering wheel’s capacitive-touch controls (of which there are many… don’t be too surprised if you find your palms pressing something randomly when you’re twirling the ‘wheel).
All GLC derivatives come with the Avant Garde pack and full MBUX system as standard, so the basic specification is higher than usual.
I do like that the wireless charging pad is situated under the centre console ahead of the cupholders. It makes it a little harder to get to your phone and, therefore, your device is less likely to distract you when you’re driving. You are more likely to forget your ‘phone when you step out of the vehicle, however.
Meanwhile, Android Auto and Apple Carplay look incredible on the big central screen and can be accessed wirelessly or through the USB-C port.
Thanks to its 2 888-mm wheelbase, the new GLC is 60 mm longer than its predecessor and the longest model in its class, which endows it with the most rear occupant space and the largest load-bay capacity.
What are the engines like?
At launch (May 2023), there are 3 derivatives to choose from (2 diesel and 1 petrol), all with 4Matic all-wheel-drive. We spent the day driving the entry-level 220d; its 2.0-litre turbodiesel engine produces 145 kW and 440 Nm of torque. The mild-hybrid system makes 17 kW and 200 Nm of boost available when required, and mostly at low speeds, in order to save as much fuel as possible when accelerating.
If you seek a good balance between performance and economy, this engine feels like the best option. We have extensive experience with this drivetrain in the GLB and know that it can easily return 5.5 L/100 km in mixed driving conditions. I’ve always found that this engine and gearbox (9-speed auto) combination provides adequate acceleration from all speeds – it doesn’t feel noticeably deficient in any department.
Those who want a bit more shove from their turbodiesel-engined GLC can opt for the 300d. It also uses a 2.0-litre mill, with significant outputs of 198 kW and 550 Nm of torque. This powertrain (also with the 9-speed auto) will perform excellently on the open road while returning reasonable fuel economy.
The petrol engine available in the range powers the GLC 300 – it’s a turbocharged 2.0 litre, but with 190 kW and 400 Nm of torque on tap. SUVs and diesel usually go better together, but if you happen to have a sponsored fuel card and an unlimited budget, the revvy petrol motor may provide the most excitement!
What’s the GLC like to drive?
Each new generation of Executive SUV feels a little more planted when cornering briskly and, therefore, seems nicer to drive than its predecessor. Our GLC rode on standard coil springs and its ride quality was notably less bouncy and crashy than that of the previous-gen model. The cabin is particularly quiet and well-insulated – it’s an area in which ‘Benz is keen to show its refinement and justify its premium billing.
Throttle and steering responses liven up markedly when you switch the drive mode from Comfort to Sport. The steering weighs up noticeably but isn’t so hefty that it feels exaggerated. The GLC wasn’t designed to be sporty, but it’s dynamic enough that you can have a bit of fun when the road gets twisty.
I would like to test a GLC equipped with the Engineering Package (with the air suspension setup and the rear-wheel steering), as the option should further improve the ride and dynamism at low speed. The air suspension also allows for an increase in ride height when required (in off-road scenarios, for example).
While the GLC is an asphalt-road-biased vehicle, Mercedes-Benz has fitted the model with useful off-road kit (if you ever find yourself in a tricky situation on your way to that well-off-the-beaten-path guest house). The camera system can project an image of the Benz’s lower extremities and what is just in front of the bumper via a transparent bonnet image between 0 and 8 kph (Land Rover has a similar system). Between 8 and 20 kph, the image is projected slightly forward so you can see upcoming obstacles.

Summary
The new Mercedes-Benz GLC introduces a higher standard specification to the Executive SUV segment; the bundling of options does make it much easier for buyers to spec the derivative of their choice, but bear in mind that when you add to the standard Avant Garde spec, it will drive the price up substantially.
The engine range available at launch covers all the bases and there are Mercedes-AMG versions on the way (either late in 2023 or early in 2024). The turbodiesel and turbopetrol engines in Mercedes-Benz’s arsenal are top-tier – the brand’s engine and drivetrain tech puts the GLC ahead of the competition.
The interior, which features the full MBUX system and comprehensive phone connectivity as standard, looks impressive in any specification; the cabin materials feel premium and, hopefully, the build quality will stand the test of time, because it’s not been Mercedes-Benz’s strongest trait of late.
The new Mercedes-GLC’s prices do appear to be on the high side considering the newcomer is around 10% more expensive than the equivalent BMW X3 and even pricier compared with the long-serving Audi Q5. On the face of it, the 2nd-generation GLC does seem to have better standard spec than its direct rivals, but be sure to do a side-by-side comparison if you really want to dig into the minutia.
