Mercedes-Benz CLS-Class vs Renault Duster

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 Renault Duster 4x4 Evolution (manual) is a driver’s car. Lots of fun for day-to-day duties and a real visceral experience if you like to have a few laughs on loose-dirt and gravel tracks. And it’s adequately capable for off-roading adventures. It also has more than its fair share of cheeky charm.

Obviously it’s not anywhere near the most capable off-road vehicle available. That’s not what it’s intended to be. But it’s one of the most fun to drive on- and off-road.

And for $36,490 (excluding on-road costs), you’ll still have cash enough for a set of all-terrain tyres and some accessories.

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?

From the outside, the Duster 4x4 Evolution has that special ‘something’ that draws your eye. It’s unassuming, yet somehow eye-catching.

It’s a chunky little AWD with ‘Renault’ across the front grille and its raised stance gives the Duster a rugged presence.

Hard angles and nifty touches, such as the concealed rear door handles on the C-pillar, add to its funky exterior.

The Duster’s interior continues the minimalist theme with hard plastic surfaces everywhere – including the dash and door armrests – and black and grey cloth upholstery, all amid a neat but uncluttered layout.

The 10.1-inch multimedia touchscreen , angled slightly towards the driver, dominates up front and caps off what is an unpretentious, functional cabin.

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.

The interior in Evolution trim matches the Duster’s no-nonsense adventure-focussed approach. It’s spartan but user-friendly.

The front seats are manually adjustable and the cloth upholstery looks like it’s hard-wearing and likely able to cope with the utter messiness of life.

I had trouble getting my phone to work via the 10.1-inch multimedia unit, but otherwise I have few complaints about the system as it’s easy enough to operate. There’s a wireless-charging pad below the screen. There are also two USB-C charging ports up front and two for rear-seat passengers, as well as two 12-volt sockets one in the front and another in the rear cargo area.

There is a mix of physical buttons and on-screen controls to operate various in-cabin functions, such as air-con.

For storage there is a glove box, a deep centre console, two cupholders, and a small shelf for your pocket clutter.

The second-row seats are roomy enough for two adults or three teens across the row and while passengers there have access to two USB-C charging ports and air vents, there’s no fold-down centre armrest.

The rear cargo area is accessed via a manual tailgate and is claimed to offer 358 litres of cargo volume when the rear seat is in use and 1424 litres when the second-row seat is stowed away.

Payload in the Duster Evolution 4x4 is listed as 503kg. The cargo area has a light, cargo hooks and a 12V socket. This Duster has a 215/70 R16 spare stored underfloor.

The 2026 Renault Duster is available as a 4x2 (automatic) or 4x4 (with a six-speed manual) in two trim levels – the Evolution and the Techno – with a choice of a turbocharged 1.3-litre four-cylinder engine (for the 4x2) or a turbocharged 1.2-litre mild-hybrid three-cylinder engine (for the 4x4).

Our test vehicle, the 4x4 Evolution, has a manufacturer suggested retail price of $36,490, excluding on-road costs.

Standard features include a 10.1-inch multimedia touchscreen (with wireless Apple CarPlay and Android Auto), a wireless smartphone charger, 7.0-inch digital instrument cluster, six-speaker Arkamys sound system, dual-zone climate control, 17-inch alloy wheels, Continental Cross Contact 215/65 R17 tyres and a 215/70 R16 spare.

There’s also a range of accessories available including Rhino Rack and Thule storage platforms and racks.

Exterior paint choices include the no extra cost 'Solid White' as well as 'Khaki Green', 'Pearlescent Black', 'Terracotta', 'Cedar Green', 'Sandstone' and 'Shadow Grey'. All metallic or premium paint adds $750 to the Duster’s price.

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 Duster 4x4 Evolution has a 1.2-litre three-cylinder turbo-petrol engine with a 48V mild-hybrid system (producing 96kW at 4500rpm and 230Nm at 2250rpm) matched to a six-speed manual gearbox.

As I said earlier, a new small 4x4 SUV with off-road capability and a manual gearbox is refreshing.

This Duster has an all-wheel drive system and the little 1422kg SUV can do the 0-100km/h sprint in a claimed 11.94 seconds.

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 combined cycle (urban/extra-urban) fuel consumption is 5.7L/100km.

On test, we recorded 6.7L/100km but we did do a half-day of light off-roading.

This Duster 4x4 has a 55-litre fuel tank so, going by that on-test fuel figure, you could reasonably expect a driving range of about 820km out of a full tank.

The turbocharged 1.2-litre mild-hybrid three-cylinder engine requires 95 RON premium unleaded petrol.

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.

My kids are learning to drive in a manual because I reckon being able to drive a manual vehicle remains an important skill to have. I only own manual cars at this point in time and it’s nice to see new cars with manual gearboxes haven’t been done away with just yet.

This all-wheel drive adventure machine is light at 1422kg and punchy, working through a turbocharged 1.2-litre mild-hybrid three-cylinder engine (producing 96kW at 4500rpm and 230Nm at 2250rpm) and a six-speed manual gearbox.

It’s sporty, with precise steering, crisp throttle response and nicely controlled ride and handling. And it’s a whole lot of fun to drive on sealed surfaces.

Throwing it around corners at (legal) speed is a barrel of laughs and driving on fast loose-dirt tracks is damn good for rally-style hilarity, all with the gruff backing track of this little AWD’s tractable petrol engine. Driving the 4345mm long, 2069mm wide and 1650mm high Duster feels like you’re punching a go-kart around a track, in a good way.

The Duster’s suspension deserves a mention here because this package, including an independent multi-link set-up at the rear, yields a firm but well-balanced overall feel.

Its tight turning circle makes it supremely easy to accomplish quick manoeuvres without fuss and it’s also a cinch to park.

Visibility from the driver’s seat is somewhat reduced through different angles to the rear and back along the vehicle’s side, but you get used to that. It doesn’t help that the camera view is muddy looking on the screen.

Those niggles aside, did I mention it’s fun to drive?

It’s not too shabby in low-speed off-road scenarios, either. The Duster is similar to Subaru’s Crosstrek and XV or the Jimny, in that this Renault’s intended use is not as a hardcore rock-crawling beast, it’s not engineered for that sort of thing.

The Duster's all-wheel drive system is well calibrated and quietly effective at detecting wheel-slip and delivering a smooth response. Driven with care, this AWD SUV is capable of off-roading at a level that will surprise some.

It has a 4x4 terrain control system with five modes – 'Auto', 'Eco', 'Mud & sand', 'Snow' and 'Off-road' – as well as a hill descent control system. None of these are engineered to turn the Duster into an off-highway mongrel but they ensure it's able to cope with mild to less-mild off-roading.

The Duster’s ground clearance (212mm) and off-road angles (31-degree approach and 36-degree departure) make it better suited to tackling off-road terrain of the light-to-moderate variety rather than door-sill deep mud holes and the like.

For reference, the Suzuki Jimny has 210mm of ground clearance and approach and departure angles of 37 and 49 degrees. The Crosstrek has 220mm of ground clearance, and approach and departure angles in the off-road-focussed Wilderness of 23.5 and 25.5 degrees.

But it’s still very capable if driven with consideration and well within the limits of its physical dimensions and off-road traction control.

Light off-roading (well-maintained gravel roads and dirt tracks in dry conditions) is fine because that’s well within the Duster’s capabilities and it results in little to no wear and tear on the vehicle.

While the Duster can handle short bursts on firm-packed sand (which I test here), sand-driving puts extra stress on any vehicle, and AWDs don’t have a lot of ground clearance, so they’re prone to bellying out on tall crests in between deeper wheel ruts on a beach.

My advice? Avoid anything beyond a well-maintained dirt track in dry weather and don’t take on any ‘4WD/ high ground clearance only' tracks, prolonged sand-driving or rock-crawling. Anything more rigorous than that and you risk damage to the vehicle’s underbody at a minimum, and mechanical damage and personal injury at worst. You’ve been warned.

The Duster’s off-road capabilities could easily be further enhanced with a set of decent light truck all-terrain tyres but, be aware, even aggressive rubber won’t turn it into a gung-ho off-roader.

For the record, it has unbraked trailer towing capacity of 750kg and braked towing capacity of 1500kg. Maximum towball download is listed as 75kg.

A bonus for Duster owners is that it can be kitted out for adventure via either Renault’s range of accessories – including all-weather floor mats, roof box, roof racks etc – or through Australia’s aftermarket industry.

The Renault Duster 4x4 Evolution (manual) does not have an ANCAP safety rating because it has not been tested.

Standard safety gear includes six airbags, AEB, driver attention alert, lane-keep assist, lane departure warning, traffic sign recognition, rear parking sensors and a reversing camera.

The Duster range does not have adaptive cruise control (only regular ol’ cruise control) or rear cross-traffic alert.

The rear seat has two ISOFIX points and three top-tether child-seat anchorage points.

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.

A five-year/unlimited-kilometre warranty with five years of roadside assistance applies to the Duster. That's average for the mainstream market.

Servicing appointments are set at 12 months/30,000km intervals, whichever occurs soonest.

Capped price servicing applies to the first five services with a total cost calculated at $2475 for the all-wheel Duster, with an average per-service cost of $495, which is getting up there for a car in this price bracket.

Renault has more than 70 dealerships across Australia.
