Mercedes-Benz CLS-Class vs Kgm Rexton

What's the difference?

Comfortable when it needs to be and sporty when you want it to be, the CLS 53 is a bit like Mercedes’ Doctor Jekyll and Mr Hyde – or maybe Bruce Banner and the Hulk is a better frame of reference for some.

While it doesn’t excel in any one particular area, its breadth of useability is commendable, but ultimately it might be its all-too-familiar aesthetics that is the biggest letdown.

From the inside, it looks and feels like any other large Mercedes model (not necessarily a criticism), while the exterior – in my opinion – doesn’t go far enough to differentiate it from the CLA.

After all, if you wanted a stylish and sporty sedan, shouldn’t feel special too?

The KGM Rexton Advance is a large 4WD wagon packing an adequate amount of appeal.

It’s nice to drive on the open road, it’s comfortable and it signals continued incremental progress for KGM in terms of quality and functionality.

It’s fine for light off-roading but its 4WD efficacy is lacking. While it's not in the same class as something like the Ford Everest in terms of refinement, comfort, and general quality, ultimately, a lot of its rivals represent greater value for money and all-round driveability as family vehicles.

And even though it does offer owners a chance to take their urban-focussed SUV into the bush, its price is climbing, and other rival vehicles offer a more refined overall driving experience.

Mercedes’ homogenised design is a bit of a double-edged sword, and while the CLS does wear its styling confidently, it probably looks a little too much like the cheaper and much smaller CLA for our tastes.

Both are swoopy four-door coupes from Mercedes-Benz, so of course there will be some similarities, but keen-eyed car spotters will notice some differences.

While the proportions are similar, the longer wheelbase and bonnet line gives the CLS a more mature look, and the extra details found in the head- and tail-lights, and front bumper stand it apart.

The changes to the 2022 version also brings in AMG’s 'Panamericana' front grille, which adds a bit of welcome aggression to the front end.

From the side, the steeply raked roof flows seamlessly into the rear, while the 20-inch wheels fill out the arches well.

All four doors are also frameless, which is always cool to see.

From the rear, quad-exhaust tips hint at the CLS’s sporty intentions, while a prominent rear diffuser and subtle boot lid spoiler also feature.

Inside, the biggest change to the CLS is now the inclusion of the MBUX multimedia system, which keeps it in line with the E-Class, C-Class and other Mercedes models.

AMG sports seats are also fitted, wrapped in Nappa leather and 'Dinamica' fabric upholstery for all pews.

Our test car also came fitted with red contrast stitching and seat belts, adding a racy streak to the CLS cabin.

Have to point out the new steering wheel that comes with the 2022 CLS, though, which mirrors the tiller offered in the new E-Class, and is a step back in terms of functionality.

It looks premium enough thanks to its chunky leather-wrapped rim and gloss black dual-spoke design, but using the buttons, especially when on the move, is difficult and unergonomic.

This design is definitely function over form, and might need a few more revisions to get it right.

Overall, we’d say the CLS is a good-looking car, but does play it a bit too safe with its styling?

The Rexton remains essentially unchanged from the previous generation and so it stays pleasant enough but generically inoffensive as are most other SUVs on the market.

Even for a city-focussed SUV, the body-on-frame Rexton looks low and while its 203mm of ground clearance is okay for daily driving it’s less than ideal for off-roading.

The only change to this Rexton over the previous generation? Pull-up sun blinds on the rear doors. Not a design change per se, but worth mentioning.

Does it set itself apart enough from other similar SUVs? Not really, but does that even matter to you?

Measuring 4994mm long, 1896mm wide, 1425mm tall and with a 2939mm wheelbase, the CLS slots neatly between the E-Class and S-Class in size and positioning.

Up front, occupants are afforded ample room for head, legs and shoulders, while the electronically adjustable seats make it easy to find a comfortable position.

The steering wheel also features a telescoping function – an always appreciated feature – and the expansive glasshouse makes things feel open and airy.

Storage options include a deep door pocket, a cubby found under the armrest, two cupholders and a smartphone tray with wireless charging capabilities.

It’s a different story in the second row, though, as the sloping roofline does noticeably eat away at headroom.

Don’t get me wrong, a six-foot-tall (183cm) adult can still slide in there fine, but the roof is dangerously close to the touching the top of the head.

Leg- and shoulder-room is pretty good in the outboard seats though, while the middle position is compromised by the intrusive transmission tunnel.

In the second row, passengers have access to a bottle holder in the door, a fold-down armrest with cupholders, backseat map pockets and two air vents.

Opening the boot reveals a cavity offering 490 litres of volume, with an aperture wide enough to fit golf clubs or luggage for a weekend getaway for four adults.

The rear seats also fold in a 40/20/40 split fashion, but Mercedes-Benz is yet to detail how much volume is on offer with the rear seats down. And as a traditional sedan, the CLS is less practical than the liftback Audi S7.

This Korean SUV has a nice but unspectacular interior, although it does have a low-key premium look and feel about it and the cabin is comfortable.

It has a familiar ease of functionality and there’s a family-friendly mix of durable plastic and soft-touch surfaces throughout the cabin.

The 2026 KGM Rexton range is a seven-seat 4WD wagon in a two-, three- (second row) and two-seat (third row) 50/50 configuration.

The leather-look seats are comfortable enough and the front seats are heated, ventilated and power-adjustable; the second-row outer seats are also heated.

The multimedia system with its 12.3-inch screen is okay to use, but I had no luck getting Apple CarPlay paired to my not-so-smart phone. And, believe it or not, that hasn’t happened to me for a long time. Note: other people were able to pair their phones to this Rexton with no problems during my week of testing.

Otherwise, functionality, storage and charge points around the cabin are satisfactory, including two USB-C ports up front (centre console) and a 12V power outlet.

The second-row seats – a 60/40 configuration, which folds, reclines and tumbles – are supportive without being overly so.

In the second row, as mentioned earlier, the only changes evident to this Rexton over the previous generation are the pull-up sun blinds on the rear doors.

There’s actually a decent amount of space for passengers in the third row here, but an adult still wouldn’t love to spend too much time back there.

The rear cargo area space of the 2026 KGM Rexton range is listed as 236 litres (with all three rows of seats in use), 641 litres (with third row stowed away), and 1806 litres (with second and third row stowed away).

There’s a 12V power outlet in the cargo area.

This new Rexton offers reasonable practicality but rivals such as the Mahindra Scorpio and LDV D90 offer just as much, sometimes more, all-round family suitability but for $5000-$10,000 less, depending on the variant.

The KGM Rexton is available in four variants: ELX, Advance, Ultimate – and the Ultimate with the optional Rexton Sport Pack.

The Advance as standard has recommended drive-away pricing of $58,200 (correct at the time of writing and includes $700 Marble Grey metallic paint). But our test vehicle also has a $1842 tow bar fitted, and a $665 electronic brake controller fitted, pushing its as-tested price to $60,707.

Standard features in the Advance include C-type design LED daytime running lights, a 12.3-inch touchscreen multimedia system (with Apple CarPlay and Android Auto), a 12.3-inch digital LCD instrument cluster, leather-accented heated and ventilated, power-adjustable front seats, ambient interior mood lighting, walk-away automatic door locking, a power tailgate, 18-inch 'diamond cut' alloy wheels and a suite of driver-assist tech including a tyre pressure monitoring system, but it misses out on the higher grades’ 360-degree surround view monitor.

The only change to this Rexton over the previous version? Pull-up sun blinds on the rear doors.

This new Rexton has plenty going for it, in terms of standard features, but rivals such as the GWM Tank 300, Mahindra Scorpio and LDV D90 offer just as much onboard but for $5000-$10,000 less, depending on the variant.

Exterior paint choices include Grand White, Marble Grey (metallic paint), Pearl White (metallic paint), and Space Black (metallic paint). Metallic paint is available for $700 on all grades, but is included in the price of the Sport Pack.

Powering the Mercedes-AMG CLS 53 is a 3.0-litre turbocharged inline six-cylinder engine, punching out 320kW/520Nm to all four wheels via a nine-speed automatic transmission and Merc's '4Matic+' AWD system.

A 48-volt mild-hybrid system, known as 'EQ Boost', is also fitted that serves up to 16kW/250Nm from take-off.

The result is a 0-100km/h acceleration time of 4.5 seconds, keeping it on pace with the likes of the 331kW/600Nm Audi S7 (4.6s) and 390kW/750Nm 250kW/500Nm BMW 840i Gran Coupe (5.2s).

While not as brutish as AMG’s eight-cylinder engine, the straight six strikes a great balance between pace and poise that perfectly suits a model like the CLS 53.

The entire KGM Rexton line-up has a 2.2-litre four-cylinder turbo-diesel engine producing 148kW of power and 441Nm of torque.

It has an eight-speed automatic transmission, part-time 4x4 with high and low range, and an auto-locking rear differential.

This is a sluggish combination and not a particularly efficient powertrain, but it does the job, albeit in a lacklustre fashion.

Drive modes include Normal, Sport and Winter modes.

Official fuel consumption numbers for the CLS 53 are pegged at 9.2 litres per 100km, while we managed an average of 12.0L/100km in our launch drive.

All of our driving was relegated to country back roads and high-trafficked urban areas however, with no consistent freeway driving.

We’ll reserve judgement on how accurate the fuel economy figures are until after we’ve had the car for longer, but the EQ Boost system is designed to help keep consumption down by being able to coast the engine in particular situations.

Official fuel consumption for the Rexton is listed as 8.7L/100km.

On this test, I recorded 10.6L/100km, but I have done a chunk of high and low-range, four-wheel driving.

The Rexton has a 70-litre fuel tank. So going by that on-test fuel figure from a full tank, you could reasonably expect a driving range of about 660km.

But remember, I'm travelling with just me and some vehicle recovery gear. You'll be traveling with your kids, your mates, your pets, your camping gear, your sporting gear, all that sort of stuff. And that extra weight will have an impact on the vehicle's fuel consumption, so just keep that in mind.

There are certain expectations on a vehicle when it wears a Mercedes badge, namely it should be comfortable to drive while also dripping with the latest tech. And here the large four-door coupe delivers in spades.

Driving the car is smooth, easy and comfortable when in its default drive setting, you can really sink into the CLS and just eat up the miles in comfort.

There are small niggles, like the 20-inch wheels and low-profile tyres (245/35 front and 275/30 rear) throw up a bit too much road noise into the cabin, but for the most part, around town, the CLS is serene, supple and supremely soothing.

However, switch it over to Sport or Sport+ and the steering gets a bit heavier, the throttle response a bit sharper, and the suspension a bit stiffer.

Does it transform the CLS into a sports car? Not quite, but it certainly dials up driving engagement to a level where you can really have some fun.

Though this isn’t a full-fat AMG in the same vein as an E63 S and doesn’t feature the ubiquitous 4.0-litre twin-turbo V8, the CLS 53’s 3.0-litre six-cylinder engine is still plenty potent.

Coming away off the line feels particularly brisk, likely due to the EQ Boost system adding a bit of poke, and even flat-footing it mid-corner delivers a noticeable surge of urgency from the creamy straight six.

However, the best of the CLS 53 experience, in my opinion, is actually the sound, with the exhaust letting off the right sort of pops and crackles in Sport+ mode on overrun.

It’s rude and obnoxious, but also completely surprising coming from the motoring equivalent of a three-piece dress suit – and I love it!

The brakes are also up to task for scrubbing speed, but our relatively brief time with the car was in extremely wet conditions, so the 4Matic+ AWD system was hugely appreciated.

The Rexton is 4850mm long (with a 2865mm wheelbase), 1960mm wide and 1825mm high with a listed kerb weight of 2136kg.

With a turning circle of 11m, the Rexton is quite nimble around town.

On road, it’s okay. It's reasonably quiet and comfortable, and though it’s not particularly dynamic – the engine and auto make for a sluggish pairing – the Rexton is sufficiently driveable all round.

Its suspension – double wishbones and coil springs at the front, independent multi-link and coil springs at the rear – is firm, mostly controlled, but ride becomes jittery on irregular sealed surfaces and that characteristic is only amplified on even mildly corrugated dirt tracks.

And it’s in the dirt where the Rexton’s limitations are quickly exposed.

The Rexton is best considered a light-duty four-wheel drive: it is quite low; its stock tyres – Nexen NPriz RH7 (255/60R18 108H) – though marketed as “all season” aren't well suited for four-wheel driving. And the Rexton’s 4WD mechanicals and off-road traction control feel dated in operation, they just don't feel as effective as they should in a very competitive SUV market.

It doesn't have a lot of ground clearance or wheel travel and its shallow off-road angles – approach (20.5 degrees), departure (20.5) and ramp over (20) – are best suited to light-duty off-roading (i.e. well-maintained tracks in national parks in dry weather).

There's a decent spread of revs here, but there's not a lot to work with in terms of how effective the Rexton is as an off-road package so if you are here for a hardcore 4WD review with tyres-ripping-the-dirt action you're in the wrong place, because the Rexton just isn't up to that. And that's perfectly fine because people won't be using it for that purpose.

Having said that, the Rexton does reasonably well with what it has on board: there’s a decent amount of torque across a spread of revs; steering has a direct feel and nice liveliness to it; throttle response is quite sharp; and there is plenty of visibility forward over the bonnet.

Its auto rear diff lock is clunky in operation, disengaging abruptly, sometimes when you’re not even up, over or through the particular off-road challenge you’re tackling. I’ve noted similar issues with the Mahindra Scorpio in the past.

But driven with careful consideration the Rexton may do – at a stretch – the type of terrain you might not think it would be capable of.

And a decent set of all-terrain tyres would also help the Rexton, but it is what it is: a light-duty, four-wheel drive.

If you're thinking of using your family go-mobile as a touring vehicle, it’s worth noting the payload is 824kg, gross vehicle mass is 2960kg and gross combined mass is 6460kg.

Towing capacity is 750kg (unbraked) and 3500kg (braked).

The GWM Tank 300, Mahindra Scorpio and LDV D90 have similarly old-school type powertrains and 4WD set-ups, but the Tank is more comfortably capable off-road and yields a better general driveability than the Rexton and those others.

The Rexton does not have an ANCAP rating because it has not been officially tested.

As standard, it has nine airbags, auto emergency braking (AEB), adaptive cruise control, forward collision warning, lane keeping assist, blind spot warning, lane change-collision warning, rear cross-traffic warning, trailer sway control, driver attention alert, front vehicle start alert and more.

Though it doesn’t have an ANCAP rating, the Rexton holds its own in terms of driver-assist tech against rivals such as GWM Tank 300, Mahindra Scorpio and LDV D90.

Like all new Mercedes-Benz models sold in 2021, the CLS 53 comes with a five-year/unlimited kilometre warranty with roadside assist over that period.

This outclasses the assurance period offered by BMW, Porsche and Audi (three-year/unlimited kilometre), and matches that available from Jaguar, Genesis and Lexus, who recently upgraded their offering.

Scheduled service intervals are every 12 months or 25,000km, whichever occurs first.

The first three planned services will set buyers back $3150, broken down as $700, $1100 and $1350 apiece.

The MY26 Rexton range is covered by a seven-year/unlimited kilometre new-vehicle warranty, and five years of roadside assistance.

A service is required every 12 months or 15,000km, whichever occurs soonest with cost per service either $418 or $522.

KGM Australia has more than 50 dealerships across the country with a decent spread across metro and regional areas. Rextons can be serviced at those dealers or at approved workshops.

The Rexton offers a competitive warranty when pitched against the likes of the GWM Tank 300 (seven-year/unlimited kilometre), Mahindra Scorpio (seven-year/150,000 km) and LDV D90 (seven-year/200,000km warranty).
