Where does the new Mercedes-Benz GLC fit in?
This is the new, 2nd-gen Mercedes-Benz GLC that arrived in South Africa earlier this. The model does battle with the BMW X3, Audi Q5, Volvo XC60 and Range Rover Evoque, to name a few of its key rivals.
Sharing its underpinnings with the locally produced W206-series Mercedes-Benz C-Class, which went on sale in early 2022, the GLC SUV inherits much of the C’s interior technology and architecture while also sharing its 2.0-litre turbodiesel engine with 48V mild hybrid technology with the C220d derivative.
This is the entry-level engine in the GLC range. Buyers can also opt for the more powerful GLC 300d or the petrol-powered GLC300, all with mild-hybrid tech. Furthermore, derivatives are offered in 2 trim lines: Avantgarde (standard – on test here) or AMG Line (if you want to ramp up the GLC’s kerb appeal).

The Avantgarde trim of the test unit is distinguished by some chrome detailing (on the lower bumper, for example), a vertically slatted grille and aluminium roof rails. This example rides on optional 19-inch, 10-twin-spoke light alloy wheels (R15 525); 18-inch 5-twin-spoke alloy wheels are fitted as standard.

For this test, we’d drive the GLC up the West Coast to Citrusdal and surrounds to have a weekend away with friends and a 2-year-old toddler – it’d be the perfect opportunity to test the GLC’s family-car skills. Mother Nature, however, had other plans. We had no idea a huge rainstorm was bearing down on us…
How the Mercedes-Benz GLC fares in terms of…
Interior specification & practicality
When you first step into the new X254-series Mercedes-Benz GLC, it’s immediately apparent that the SUV’s cabin architecture is lifted straight from the now-familiar C-Class. Fortunately, that’s a good thing!
It looks ultra-modern. The interior of the Sindelfingen-based brand’s 2nd-gen executive SUV exhibits a noticeably tech-forward design approach, highlighted by the 11.9-inch portrait-orientated touchscreen equipped with Benz’s latest MBUX operating system. The large and attractive touchscreen interface is intuitive, but you may have to spend some time to fully familiarise yourself with the system’s functionality.
Furthermore, a 12-inch all-digital instrument cluster amplifies the cabin’s tech ambience appreciably. It can be easily configured to display themes to suit your mood (or taste) by using the mounted capacitive-touch controls on the multifunction ‘wheel. These controls, however, are very sensitive (overly so); you can easily activate an option or function inadvertently when you twirl the ‘wheel, which can become tiresome. Perhaps ‘Benz should revert to conventional button controls when it facelifts the model?
As for the GLC 220d 4Matic Avantgarde’s leather-trimmed front sports seats, we found them to be both cosseting and well-bolstered. Rear passenger space is adequate, with sufficient leg and headroom.
While the GLC’s interior fit-and-finish is generally good, which is to be expected from a contender in this segment, some of the trim elements (particularly in the centre console) are of questionable quality. Upon closer inspection, you’re likely to notice various insubstantial plasticky, albeit pretty-looking, bits of trim.
The driver and front passenger have access to a wireless charger and buyers can opt for the USB Package Plus (R6 210), which provides half a dozen USB-C fast-charging ports throughout the cabin.
This test unit was also fitted with a full-length panoramic sunroof (R29 394), which gave the cabin a spacious and airy feel.
In terms of practicality, we could install the toddler’s car seat at the back without any fuss. The load bay offers 620 litres of capacity, which expands to 1 680 litres with the seatback folded flat. Just note that the bay is quite shallow, so taller or bulkier items will have to be shifted around to achieve an ideal fit.
Ride quality and handling ability
When departing from Cape Town, we set course for the Leopard Valley Resort just north of the farming town of Citrusdal. Travelling on this stretch of tarmac gave us a good opportunity to test the Benz’s 48V mild-hybrid powertrain, which delivers total system outputs of 162 kW and 440 Nm of torque.
It’s a refined powertrain – engine noise is very well suppressed with precious little “diesel clatter” audible inside the cabin (especially when travelling on the open road). The refinement is further highlighted by the smooth-shifting 9-speed automatic transmission, which seems well-calibrated with the power unit.
As far as the test unit’s performance was concerned, the GLC 220d performed admirably, with punchy off-the-line acceleration allied with satisfactory overtaking ability on the freeway. Despite this being the entry point into the GLC range, the 220d 4Matic is anything but underpowered. As it rained during much of our journey, the Benz’s 4Matic all-wheel-drive system provided ample reassuring road-holding.
This test unit was also equipped with Mercedes-Benz’s Engineering Package (R57 753); apart from an absorbent (and driver-adjustable, of course) air-suspension setup, it incorporates rear-axle steering, which is said to improve manoeuvrability at low speeds while enhancing stability and agility at higher speeds. We found the GLC’s steering pleasingly sharp, which is a boon when you feel the need to drive enthusiastically on the odd occasion; the responsive tiller was an unexpected bonus of the package.
Fuel efficiency
Mercedes-Benz claims an average fuel consumption of 5.2 L/100 km for this derivative, which sounds ambitious. Yet, we saw indicated returns of 6-6.2 L/100 km, which is very good for a vehicle with a kerb weight of 2 000 kg, not least one that had a full complement of occupants and their luggage on board.
Overall, the Mercedes-Benz 220d 4Matic Avantgarde offers a satisfactory level of performance and economy, but should buyers want – or need – more power for towing, for example, perhaps the 300d 4Matic Avantgarde (with 215 kW and 550 Nm) will be a more attractive, albeit pricier, proposition.
Off-road ability
Is the 2nd-gen Mercedes-Benz GLC capable of venturing off-road? The short answer is yes, but within reason, of course. Like its rivals, the X254-series model is an executive SUV designed to serve in an urban environment, but it’s capable of doing light off-roading (or “soft-roading”) if needs must.
For those of you who will be traversing rougher terrain in your GLC, Mercedes-Benz does offer an Off-Road Engineering Package (R9 200), which includes underbody protection as well as a suspension lift with an additional 20 mm of clearance; the latter is useful when you are driving over very uneven terrain.
With the weather in the Citrusdal worsening by the hour, we had no choice but to engage in some “mild” offroading in the GLC 220d 4Matic Avantgarde… When we arrived at Leopards Valley, we discovered that the stormwater runoff from the surrounding mountains had flooded the entrance of the resort and, with daylight fading rapidly, we had no choice but to cross the torrent then and there.
While the initial flood crossing posed little challenge for the GLC, an overnight storm – accompanied by heavy rain – resulted in the whole road being washed away, effectively stranding us in Leopard Valley for the weekend.
With no way of getting the GLC 220d 4Matic Avantgarde out of the valley safely, we had to leave the ‘Benz behind until the road was rebuilt, which of course brought our test of the Benz to a swift end…
Pricing and Warranty
The Mercedes Benz GLC 220d 4Matic Avantgarde is priced from R1 227 271 and is sold with a 2-year/unlimited km warranty and a 5-year/100 000 km maintenance plan.
With a few optional extras fitted, our test unit’s price tag came to about R1 377 000.

Verdict
The 2nd-gen Mercedes-Benz GLC demonstrates that the Three-pointed Star has made notable improvements on the 1st model, particularly in terms of interior execution, onboard technology and overall performance, refinement and efficiency. Even in its base form, the mild-hybrid GLC offers pleasing performance; Mercedes-Benz has done phenomenal work to deliver mild-hybrid powertrains that can – and do – perform, but not at the expense of fuel economy. The GLC 220d is a frugal runner!
While it’s not short on performance, we think that some buyers might want the additional power offered by the GLC300d, but then again, that derivative’s price starts at R1 342 430. Just bear in mind that you will likely have to budget for a few of Benz’s nice-to-have options, which will hike the price even further.
As far as its rivals are concerned, the new-gen GLC is the newest offering in its segment and it’s duly the most modern and desirable executive SUV available from new. The new GLC is considerably more expensive than its direct Audi Q5 and BMW X3 equivalents, for example; however, it is competitively equipped with standard features, which might well convince buyers to fork out the additional moolah.
If your heart is set on the X254-series Mercedes-Benz GLC – provided that you’re able to afford one – you’re unlikely to be disappointed by what the Three-pointed Star’s latest executive SUV has to offer.
It’s also important to highlight that the Mercedes-Benz GLC 220d Avantgarde is a finalist in the Executive SUV category of the 2023/24 Cars.co.za Consumer Awards.
