Mercedes-Benz CLS-Class vs Renault Megane 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 design for the Renault Megane E-Tech is top-notch and the eco-conscious footprint is even better. It’s an easy and comfortable car to be in but the price is a smidge too high in my opinion when you consider there’s currently only one choice for us Aussies and it’s a mid-spec variant at that. It also misses out on some items its rivals have but is a solid EV to consider for urban dwellers.

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 E-Tech’s plump body panelling gives me some cute marshmallow vibes from certain angles but there are enough features to keep it looking slick, like the fun LED headlights, massive 20-inch alloys and optional two-tone paintwork.

I’m also a fan of the door handles on the E-Tech as they add some nice focal points, because the front has auto-flush handles that pop out on approach and the back door handles are positioned on the C-pillar.

If you're eco-conscious the E-Tech ticks the box because Renault has designed it to be 90 per cent recyclable.

The body is made of aluminium and can be reformed and shaped into new products at the end of its life. The interior materials are made from recycled fabrics and trims; even the lithium-ion battery is free from any rare earth minerals.

Head inside the cabin and the grey knit trims and upholstery on the seats, doors and dashboard creates a cabin space that feels warm and inviting. It's a similar feel to the Polestar 2 - simple but refined.

Although, with my kid around I have higher anxiety about dirtying them!

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 E-Tech’s cabin is fairly roomy up front with plenty of head- and legroom. The front seats are super comfortable with powered lumbar support and I wouldn’t mind them not being powered if the price point was a bit lower. 

The rear seat is comfortable enough once you get seated but the top of the door apertures are low, and I have to duck my head to get in and out.

Your head also brushes against the roof lining in the back which isn't terribly comfortable, especially considering there is no fold-down armrest to lean on.

The front row benefits the most with individual storage and you get a lot of options to choose from but the centre console is one of the most practical I’ve seen for the class. Lots of pockets and nooks that feature adjustable 'walls'.

You get a single permanent cupholder but with the removable walls, accommodation for a second cup or bottle, can be catered for.

Underneath the multimedia screen you get a dedicated phone shelf, which I love using.

In the rear, you get two map pockets and shallow bin storage in each door.

The charging options are good with two USB-C ports in each row as well as a 12-volt outlet and a wireless charging pad up front but you miss out on V2L (Vehicle to Load) functionality in this model.

The 9.0-inch touchscreen multimedia system looks great headlining the dash and is easy to access and use. The system rebooted once on me while driving but other than that everything is responsive.

You get wireless Apple CarPlay and Android Auto and the CarPlay is easy to get started.

The steering wheel has numerous stalks, controls, regen paddle shifters and even the gearshifter on the column, too. It takes a beat to get used to it but I like how driver orientated it is.

The boot offers great storage at 440L but it’s a deep well, which might be annoying if you’re unloading heavier gear. There is underfloor storage for the cables, too, and like I said, you miss out on a powered tailgate.

For the moment, the Megane E-Tech is being offered in only one grade for the Australian market and that’s the Techno EV60, which is the mid-level version of Renault’s brand new EV.

The EV60 is priced from $64,990, before on-road costs, and that positions it right in the middle of its rivals. The nearest competitor is the Hyundai Kona Extended Range at $60,500 MSRP, newcomer Toyota bZ4X 2WD slides in at $66,000 MSRP and the Volvo C40 Plus sits at $78,990 MSRP.

The E-Tech comes with a decent array of features for a mid-spec variant and premium items include heated front seats, a heated steering wheel, a digital rear view mirror and wireless functionality for Apple CarPlay and Android Auto but you do miss out on items like a powered tailgate and electric front seats which most of its rivals sport.

Technology looks good with a 9.0-inch touchscreen multimedia system, 12.3-inch digital instrument cluster, dual-zone climate control, faster USB-C ports (four total) and a wireless charging pad.

Sound is covered by the Arkamys Auditorium sound system with six speakers and the mood can be set with the 48-way configurable ambient lighting system.

Despite missing out on a powered tailgate, the EV60 has some features that still offer convenience like keyless entry, heated and auto-folding side mirrors and auto-folding flush door handles that pop out on approach (front only).

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 Techno EV60 has a single electric motor. It produces a power output of 160kW and 300Nm of torque, and Renault says it will sprint from 0-100km/h in 7.4-seconds.

That's perfectly adequate for keeping up with traffic or getting  around town. You only notice a sluggishness with power when you have a full load of gear. Flipping it to 'Sport' mode make it feel peppier, if you ever need it.

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.

The official energy consumption figure is 15.6kWh/100km and I averaged 13.9kWh after a fair mix between urban and open-road driving.

That’s outstanding consumption but the official driving range for this E-Tech’s 60kWh lithium-ion battery is up to 454km, which is similar to the Hyundai Kona Electric but I still had an eye on the range during longer trips.

The E-Tech has a Type 2 CCS charging port which means you can benefit from faster DC charging speeds, however, it can only accept a top speed of 7.4kW on AC power.

On a 7.4kW AC charger, you can go from 0-100 per cent in a little over nine hours but on a standard 2.3kW house plug, that jumps up to over 30-hours. 

On a 130kW DC charger expect to go from 15-80 per cent in as little as 30 minutes, which is pretty convenient if you have access to one.

Sadly, the E-Tech doesn’t have vehicle-to-load capability, so you can’t power or charge bigger items.

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.

I have mostly loved driving the E-Tech. It's easy to cruise around in and the power is adequate for open-road driving but it prefers an urban environment.

The power can feel a bit lacklustre when you are carrying lots of people or gear but you mostly feel that when you're on a steep incline and trying to keep up your speed.

The steering is crisp and that makes the E-Tech very responsive to drive. The power is delivered smoothly and it feels well-balanced when you put your foot down.

There is more roll in corners than I was expecting but the car still feels firmly planted. 

The ride comfort is great. The suspension is more firm than soft which means you feel the road but it's not a major bother. There is a bit of wind noise at higher speeds, as if the door isn’t properly sealed by a millimetre but it doesn't annoy me. 

The regenerative braking is controlled by paddles on the steering wheel and you have three levels plus a one-pedal function to choose from.

The single pedal set-up is pretty smooth, even in stop/start traffic, but it’s great to be able to quickly change modes on the go.

The smaller size of the E-Tech makes it an easy car to manoeuvre in a small car park. You get front, rear and side parking sensors which is great because the reversing camera isn’t as clear as it should be for this price level. 

The E-Tech has a maximum five-star ANCAP safety rating from testing in 2022 and has seven airbags, including a front centre airbag.

The EV60 comes with lots of passive safety features including dusk sensing auto LED headlights, LED DRLs, a rear fog light, child safety locks, tyre pressure monitoring, traffic sign recognition tech, an intelligent seatbelt warning, a reversing camera plus front, rear and side parking sensors.

Active safety equipment includes items like blind-spot monitoring, driver attention alert, rear collision warning, forward collision warning, rear cross-traffic alert, lane departure alert, lane keeping aid, and adaptive cruise control (with stop and go).

You also get a digital rear view mirror which is essential as the back window is narrow and the camera feed provides a clearer view than you’d have without it.

The rear row also features ISOFIX child seat mounts on the outboard seats and three top tethers but two seats will fit best. The front passenger seat also has ISOFIX child seat mounts and a top tether.

AEB with car, pedestrian, cyclist and junction turning assist function is operational from 8.0-80km/h (160km/h for cars) but it is common to see that starting figure sit closer to 5.0km/h.

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 E-Tech comes with a five-year/100,000km warranty, but it’s usual to see an unlimited km term for the class. The battery is covered by an eight-year or up to 160,000km warranty term.

Service intervals are reasonable at every 12 months or 30,000km and you also get five-years roadside assistance included.

Pricing over the first five years ranges from a low of $230.04 to a high of $519.62, averaging out at pretty competitive $317.72 per service. No capped-price deal is available.
