Mercedes-Benz CLS53 vs Renault Scenic E-Tech

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 Scenic E-Tech is lining up against some heavy-hitting competitors, but Renault Australia admits it has one top of mind - the Kia EV5. The Kia’s a quality package and if you’re in the market for a mid-size electric SUV, you’ll no doubt have it on your shopping list. And you should have a look at this slightly smaller car, as well. It has the refinement, practicality and safety to stand up confidently in a rapidly expanding segment.

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?

There are some design tips of the hat to Scenics past in this latest electric version, including blacked-out door pillars and a recognisably angular C-pillar treatment.

But despite the fact it debuted at the Munich IAA Motor Show in late 2023, from its slimline headlights and jagged grille to its sculpted flanks and saw tooth rear end, this fifth-generation Scenic looks contemporary from every angle.

A highlight is the large Renault diamond logo sitting at the centre of a faux upper grille, surrounded by a multitude of the same elongated hexagon shape as a cool recurring graphic, the pattern merging neatly into the headlights.

Speaking of which, the LED beams can be set to produce an elaborate welcome sequence as you approach the car.

The interior feels slick and screen-rich but not at the expense of user-friendly physical controls for audio, ventilation and other commonly used functions.

Recycled fabric on the dashboard and headliner looks and feels good while doing its bit to suppress cabin noise.

Speaking of which, the Scenic is Renault’s poster child for the use of recycled materials in its construction and end of life recyclability.

Everything from ferrous components consisting of 37 per cent recycled materials to a bonnet and doors made of up to 80 per cent recycled aluminium.

The dashboard cowling is made from kenaf, a plant fibre similar to jute; the steering wheel cover is 51 per cent bio-sourced; the cockpit uses 26 per cent recycled plastic; the storage bins in the door panels are 45 per cent recycled fibre, the floor mats are 54 per cent recycled plastic bottles and the seat upholstery is 100 per cent recycled fabric. The list goes on and on, but you get the idea.

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.

In terms of how it all works in practice, at just under 4.5m long, close to 1.9m wide and less than 1.6m tall with a 2785mm wheelbase, the Scenic is more compact than the larger BYD Sealion 7 or Zeekr 7X, for example.

But there’s plenty of breathing room up front, with the centre screen angled towards the driver enhancing the cockpit feel for the one doing the steering.

There are large carpeted bins in the doors with room for bottles and a lidded storage box between the seats doubles as a centre armrest. That lid slides forward by 70mm to cover a small storage cubby under the front of it, which is a handy trick.

Locating the gear selector on the right-hand side of the steering column liberates extra space for a centre cupholder and large console storage bin. There’s a generous glove box and a wireless smartphone charger under the centre screen includes a rubberised base and two lugs to stop devices sliding around. Power and connectivity runs to two USB-C ports and a 12-volt socket.

Moving to the second row, sitting behind my 183cm driving position, while toe room is a little tight (with the driver’s seat set low down), there’s heaps of leg and headroom as well as enough shoulder room (and foot room thanks to a flat floor) for three adults on short to mid-length trips. A pair of adjustable centre air vents is also a welcome inclusion.  

Storage includes door bins (again with room for bottles), large and device-sized pockets on the front seat backs and the pièce de résistance is the evocatively named ‘Ingenious armrest’, which includes a storage area and two cupholders at the base of articulated horizontal arms that allow passengers to mount a phone or tablet at various angles in rubberised slots for joint or solo viewing.

It is, indeed, ingenious and four USB-C plugs (two in the armrest, two near the air vents) mean back-seaters won’t be short of power options.

Boot volume with the rear seats upright is useful at close to 545 litres (VDA), expanding to around 1670L with the 40/20/40 split-fold second row lowered. A power tailgate is standard across the range.

There are bag hooks, tie-down anchors, lighting and a 12-volt socket back there, although for V2L (vehicle to load) functionality you’ll need an accessory adapter to plug into the charge port.

Maximum braked trailer towing capacity is a handy 1100kg, but there’s no spare tyre, only a repair/inflator kit, which isn’t good enough.

The Scenic E-Tech starts from $55,990, before on-road costs, for the entry-grade Techno. Then there’s the Techno Long Range for $59,990, BOC, while the flagship Esprit Alpine comes in at $65,990.

That’s sharp relative to competitors and follows the brand getting a reality check with the Megane E-Tech after it launched here in late 2024, Renault shaving $10,000 off its price only a few months later.

Equipment highlights across the line-up include a 12-inch multimedia touchscreen, a 12.3-inch driver display, sat-nav, adaptive cruise control, a 360-degree surround-camera view, all LED exterior lights, wireless Android Auto and Apple CarPlay and six-speaker Arkamys audio.

There’s also dual-zone climate control, an electric tailgate, auto-folding side mirrors, cloth upholstery, heated front seats and steering wheel, 48-colour ambient interior lighting, keyless entry and start and 19-inch alloys (on the Techno models).

Then you can fold in over-the-air updates, access to remote services via the ‘MyRenault’ app and Google In-Built that enables voice-control for up to 70 car functions.

The Esprit Alpine ups the ante with 20-inch rims, nine-speaker Harman Kardon audio, synthetic leather and cloth seat trim, six-way power adjustment (with memory settings) for driver and front passenger seats, a massaging driver’s seat, brushed metal pedal covers and facial recognition for seat and mirror settings.

In short, the Scenic is well-equipped relative to its competitive set and cost of entry, with Renault confirming there are mainly demonstrator cars in dealers at the moment, with the majority of stock landing in late May or early June this year.

There are three optional paint choices - metallic ($800), two-tone ($1000) and matt ($1200), the latter exclusive to the Esprit Alpine.

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.

Like its Megane E-Tech sibling, the Scenic E-Tech uses an excited synchronous motor which Renault says is more efficient than the more commonly used permanent magnet type, with the bonus that it uses no rare earth materials.

The entry-level Scenic E-Tech Techno's fitted with a 60kWh NMC battery. Its electric motor transfers 125kW and 280Nm to the front wheels and Renault claims a 0-100km/h time of 8.6 seconds.

The Techno Long Range and top-spec Esprit Alpine pack an 87kWh battery and a more powerful motor, raising outputs to 160kW/300Nm and lowering the 0-100kmh sprint time to 7.9 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 energy consumption numbers for the combined (urban/extra-urban) cycle are close between the two powertrains at 16.3kWh/100km for the Techno and 16.8kWh/100km for the Techno Long Range and Esprit Alpine, which are bang on average for the class.

Range for the standard Techno is 430km, which is at the lower end of expectations for a medium electric SUV but adding the bigger battery pushes that number out to 625km, which is much healthier and useful day-to-day.

On the launch drive program, which took in some urban but mostly rural B-road running, we saw an average consumption figure of 17.1kWh/100km in the Esprit Alpine, which is pretty good in those conditions.

The car’s 400V electrical architecture allows for DC charging at up to 130kW for the entry model and 150kW for the bigger-battery variants.

At that speed, claimed 15-80 per cent charge times are 32 and 37 minutes, respectively. Not the best, not the worst. AC charge capability is 11kW on all models and a Mode 3 charging cable is included.

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.

Renault says the entry-grade Scenic Techno will accelerate from 0-100km/h in 8.6 seconds with the more powerful Techno Long Range and Esprit Alpine lowering that number to 7.9sec. So, it’s quick without being scary fast.

It’s certainly nippy in traffic and at the risk of stating the bleeding obvious, quiet. Even in the context of premium EVs the Scenic is quiet and refined.

Suspension is strut front, multi-link rear and the car feels super planted. The launch drive took in some reasonably rapid twisting corners and there’s no hint of lateral movement in the car. Body roll is minimal, too.

Tyres are energy-efficient Michelin e.Primacy (Techno - 205/55x19 / Esprit Alpine - 235/45x20) and the steering is quick with a relatively low number of turns lock-to-lock. It’s never jerky or too sharp. Rather, it means the car starts to turn into a corner the instant you apply steering lock.

That said, the feel between your hands on the wheel and the front tyres on the road is less than intimate.

There are four drive modes - ‘Comfort, ‘Eco’, ‘Sport’ and ‘Custom’. None of them adjust the suspension tune, it’s more about accelerator response and we found Comfort delivers the best blend of right-foot urgency and overall composure.

Most of the braking you’re going to do will be courtesy of the regenerative system and there are five levels, adjustable via steering wheel paddles, including the most aggressive single-pedal mode.

The one-pedal setting pulls the car up nice and progressively and if you do need to use the physical brakes, they’re ventilated discs all around. Some bite on initial application, but even on downhill corner sections, leaning on them quite hard, they perform well without drama.

Under the heading of miscellaneous observations, you can sense the ADAS (Advanced Driver Assistance Systems) including functions like lane-keeping assist doing their thing occasionally, but it’s all quite subtle, which is a good thing.

The Esprit Alpine’s sports front seats remained grippy and comfortable after a couple of hours behind the wheel. And it’s worth noting the Scenic’s relatively compact 10.9-metre turning circle helps in slow-speed manoeuvring.

Speaking of which, some of the modes in the audio system and external warning sounds for pedestrian safety have been designed by French composer and performer Jean-Michel Jarre, noted for his electronic, ambient-style music. Hats off to Renault for commissioning him.

The Scenic E-Tech has a maximum five-star ANCAP rating from assessment in 2022 with active crash-avoidance tech including AEB (with pedestrian and cyclist detection and junction assist), adaptive cruise control, lane departure warning and lane-keep assist, blind-spot detection, traffic sign recognition, a 360-degree camera view, rear cross-traffic alert, driver fatigue monitoring and tyre pressure monitoring as well as front, side and rear parking sensors.

If a crash is unavoidable, there are seven airbags onboard including a front centre bag and for child seats there three top-tether points across the second row with ISOFIX anchor in the outer positions.

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.

Warranty is five years/100,000km, which is well off the market pace with many competitors at seven, eight and up to 10 years conditional. The battery warranty at eight-year/160,000km matches the market.

Roadside assistance is included for five years, service is recommended every 12 months/30,000km and fixed price servicing is available at a reasonably sharp average of $325 per workshop visit for the first five years.

Renault has 52 dealers across the country covering major cities and key rural areas.
