Where does the Mercedes-Benz GLS facelift fit in?
We get to hear some exceptionally exaggerated marketing statements in this line of work, but “the S-Class of SUVs” has to be one of the boldest. How can a three-row SUV ever compare to an icon of the luxury world?
The GLS has been facelifted for 2024 and the updated model gains a new bumper, new radiator grille and new-look tail lights. Inside, the GLS now features some trim enhancements, an updated MBUX infotainment system, and a new-look steering wheel.
When it comes to high-end 7-seater rivals at this price-point, your options are few. The BMW X7 is the GLS’ closest rival, while the updated Audi Q7 will be offered in a three-row configuration when it arrives in SA in early 2025.

What are your other options? The Jeep Grand Cherokee L in Summit Reserve trim offers a tremendous amount of features and space, and is definitely worth a look. The Land Rover Discovery may have been overshadowed by its Defender (also available in three-row) sibling and represents a great-blend of comfort, space and offroad capability. The Toyota Land Cruiser 300 , Volvo XC90 and GWM Tank 500 are also worth consideration.

How the Mercedes-Benz GLS facelift fares in terms of…
Performance and Efficiency
At 2.6 tons and over 5 metres long, the GLS is one of the biggest vehicles offered for sale in South Africa and to get this massive three-row luxury family SUV about is a 3.0-litre turbocharged diesel 6-cylinder engine. Outputs of 270 kW and 750 Nm drive all four wheels via a 9-speed automatic transmission, but it’s worth mentioning there’s a mild-hybrid system that adds an extra 15 kW and 200 Nm for brief periods.
The average consumer still cannot put the terms ‘diesel’ and ‘performance’ together, but we let our test data do the heavy lifting. With its sportiest mode activated, the GLS 450d ran to 100 kph in 5.95 seconds, a two tenths quicker than claimed. For context, the benchmark boy racer Volkswagen Golf GTI does the same dash in just over 6 seconds and that’s over a ton lighter with two fewer seats.
A deep dive into the engine and performance analytics shows an engine that starts to deliver train-pulling power almost from the get go, with peak torque available from 1350-2800 rpm with the hybrid e-boost motor supplying 200 Nm for a few seconds. Overtakes? Crushed with minimal hesitation. We say minimal as the car does have 9 gears to shuffle through to find that sweet spot and the slight pause is the calm before all 750 Newtons reach the tarmac.
Of course, a large family-orientated SUV needs to be able to go the distance and the GLS features a 90-litre fuel tank and if you’re driving conservatively, you should get over 1000 km on a single tank. Mercedes-Benz claims 7.5 L/100 km but in reality, you’re going to be seeing double figures and the best we could get was around 11 L/100 km with the majority of our driving in built-up areas.
Features and Practicality
The cabin of the GLS looks as premium as they come and there are two large screens featuring an updated version of the MBUX software. There are customisable themes for the instrument cluster, like this offroad mode which highlights some cool data. Of course, if you’re serious about off-roading, then read on.
In terms of fit and finish, there’s an abundance of high-quality materials (although some of the switchgear feels a bit cheap in places) and the seats are sublime. The supportive and ultra-comfy front two seats gain a basic massage functionality on top of heating and cooling.
Although there are plenty of high-quality materials to be found, one disappointing aspect is that there are some scratchy plastics lower down in the cabin. We also found some of the switches quite cheap and flimsy, which you don’t expect from such a posh car. The standard Burmester audio system is excellent, but if you take your car audio serious, then look at the uprated 3D system with 29 speakers for an additional R120 400.
We’ll touch on the drive below, but if you’ve made it this far, you’re undoubtedly interested in the GLS’ passenger-carrying abilities. The second row of seats are able to recline, there’s climate control as well as USB power sockets.
If you want further comfort, Merc will sell you ventilated and cooled rear seats that also offer massage functionality. Space? Yes, plenty and this 1.91 metre tall author was able to sit behind himself with plenty of knee- and headroom.
What about that third row? The last two seats are surprisingly spacious and offer cupholders and USB ports for additional convenience, on top of the ability to recline slightly. With the final row deployed, boot space drops, but you still have enough room for things like small carry-on luggage.
If it’s space you’re after, you can use the electronic panel in the boot to stow all the seats and Merc says 2 400 litres of cargo space becomes available so we reckon that’s multiple sets of golf clubs, plus a mountain bike and probably a flat-screen TV. We think there’s enough space here for an inflatable mattress too…
Ride and Handling
We were hopeful of all-encompassing comfort, as the GLS features air suspension but the ride quality is a mixed bag. On perfect roads, yes the GLS glides along like a 5-star yacht through the Mediterranean but we got the sensation that it was set up on the firmer side. Imperfections like under-tar tree roots and those small nasty speedbumps did tend to unsettle the ride a bit, something that we don’t think is appropriate given the positioning of a vehicle like this. To be fair, it’s not just the GLS which tended to crash over the firmer stuff, here’s looking at you Volvo XC90…
We suspect the ride quality hinges on wheel selection. Our test unit was fitted with 21-inch wheels wrapped in 275/45 rubber and we can only wince at the thought of customers speccing their cars with the 23-inch units! They’ll look great, sure, but a brittle ride is almost a guarantee.
Something worth noting if you’re interested in the GLS, there’s no spare wheel. Instead, you get tyre sealant and a compressor, and during the photo shoot, the back left wheel picked up a little rusty nail which started a slow deflation. Fortunately, we weren’t too far out and the excellent Mercedes-Benz fleet management team promptly sorted us out.
There is a positive to a firmer ride setup and that means the GLS doesn’t roll around the corners. The GLS manages to hide its mass well and body control for a vehicle of this size is impressive.
The steering setup is surprisingly precise and direct, with ample feel. This is a good thing as something as large as the GLS requires accuracy when driving in the city. Interestingly, the GLS doesn’t feature all-wheel steering, which would be useful when it comes to parking and confined spaces. Yes, the 360-degree camera is of excellent quality, but it’s still stressful to manoeuvre such a large vehicle.
What about the off-road capabilities? The vehicle is equipped with all-wheel drive and air suspension, which depending on the mode/setting, the GLS features from 175 mm to 260 mm of ground clearance. Tick the Off-road Engineering Package for R41 000 and you get a further 30 mm of clearance, armour to protect the vulnerable underbelly as well as a specific offroad mode which includes even more details and graphics. The jury’s out on whether you’d risk taking this 7-seater premium SUV through the roughest terrain, but it’s reassuring to know there’s provision for such.

Verdict
With the world’s consumers still obsessed with the high-riding SUV, sedans have fallen out of favour. Pity, as the driving dynamics are more involving, but when you want ultimate luxury and capability, dynamics is low priority. Don’t believe us? Take a look at your favourite manufacturers and count the number of sedans in comparison to the array of SUVs…
Right now, the 450d is the pick of the GLS range and while there’s considerable desirability for either the AMG-sourced 580 and full-fat 63 AMG, the diesel engine is the most logical powertrain for the market. Granted, it’s not as quick as its petrol siblings, but we feel its economy and range between fill-ups makes it far more sensible. So, is it worthy of the S-Class association? No, it’s simply superior to the iconic sedan thanks to a bigger array of talents like genuine 7-seater space and off-road capability.
