Mercedes-Benz S-Class vs Renault Megane

What's the difference?

Mercedes-Benz set out to restore the S-Class' place amongst the greatest sedans in the world.

In the heavily-optioned, near-$250K-plus S450 as well as the extended S450L at $300K as tested (the sweet spot of the range for now), we reckon the Germans have succeeded, pushing safety, comfort and technology boundaries, in a package that is true to the heritage of the series.

Tax-fuelled sky-high prices will certainly keep the S-Class niche in Australia, but the car is more than good enough to dominate its tiny corner of the upper-large luxury car sphere.

The best new car in the world? We reckon it's highly likely. Mission accomplished, Mercedes.

If the Renault Megane RS Trophy is your dream car let me say this: there’s no overarching reason that I’d say you shouldn’t go ahead and buy it. 

But with so much amazing competition in this part of the market, it’s hard to put it ahead of its rivals. And it’s going to be even harder for it to stay high on the contenders list as more new metal arrives in the coming years.

Most Mercedes models have followed the Russian Doll-style cookie-cutter styling theme, and the heavy family look continues with the W223.

Still, the flush door handles do add a touch of Tesla-esque modernity, while the elegant silhouette and clean lines are in keeping with the luxury aspirations. Larger in every dimension compared to the old W222, the S450 is some 71mm-longer in wheelbase (3106mm) than before while the LWB's has stretched out by 51mm (3216mm), benefiting proportions as well as interior packaging.

AMG-branded wheels look sporty but – in the S450 at least – they're perhaps a tad too gangster. A set of flush alloys would give it a more-modern and techier appearance, in our opinion.

Overall, however, the S-Class ‘7' possesses the prerequisite richness of design. It isn't as bold and mould-breaking as models like the W116 were back in their day, but the styling is still a success.

By the way, the latest S-Class is the first Mercedes to employ the MRA2 longitudinal platform, which is rich in lightweight steels (50 per cent aluminium), is correspondingly stronger than before but also 60kg lighter.

With a drag co-efficiency rating as low as 0.22Cd on some overseas grades, the W223 is one of the most aerodynamic production vehicles in history.

The Megane RS Trophy’s dimensions don’t really communicate just how chunky it really is. At 4364mm long on a 2670mm wheelbase, 1875mm wide and 1435mm tall, it is pretty conventional in terms of size for the segment.

But it packs a lot of style into that size. I for one love those broad hipped wheel-arches, the signature LED headlights and chequered flag lighting signature at the bottom of the bumper, and the bright, eye-catching colours available really just ram the message home that this isn’t your average Megane.

I could happily leave behind the red flecks on the wheels, which look a bit too blingy and not quite ‘lightweight racing-spec’ to me. But they obviously appeal to a certain buyer - maybe someone who wants a bit more drive-by flair, as opposed to track-day talking points.

The Trophy model builds upon the Cup variant, using the same chassis and hardware under the skin, and therefore running the brand’s 4Control four-wheel steering and a mechanical Torsen limited slip diff. More on that in the driving section below.

Exterior design and styling are one thing - but you probably spend more time sitting inside your car than just admiring it from a distance. How does the interior of the RS Trophy stack up? Check out the interior images to make up your own mind.

For the beginning of our day with the S-Class, we were chauffeured from home to a mansion in Kew, a blue-chip Melbourne suburb. Our heavily-optioned S450L featured most of the aforementioned extras – including the Business Class Package and Rear Entertainment Package – and the experience was predictably, sumptuously memorable.

Reclining individual rear seats with easy-reach tablets, armrests offering access to all multimedia and available climatised and massaging cushions and backrests... we're no longer in our normal ride, Toto.

Yet, all these trinkets and gizmos are mere add-ons, that can turn a stretched Caprice into a flash hen's night carriage if enough money and glitz is thrown at it.

No, the new S-Class must impress in an altogether less tangible and more philosophical manner, involving all the senses, and not just what we see, hear and touch. It must appeal beyond the superficial. Otherwise, it is not a large Mercedes-Benz luxury sedan in the classic manner.

This is a Herculean task for the Stuttgart designers and engineers. By and large, though, the Three-Pointed Star has succeeded in achieving something special.

In its perception of peerless quality and engineering, the W223 is striving to move forward and look back simultaneously to the glory days of the seminal W126 (1980-1991). This is through meshing traditional virtues like solidity and quality materials while dazzling its passengers with technology that is still friendly enough to want to enhance your experience.

You can sink into the soft lounge seats, watch the world pass by silently outside and never be aware of the road underneath or the engine ahead. Double glazing, exquisite and aromatic fabrics and materials and lush tactile surfaces work their magic inside the car, while an airtight and aero body, solid platform, air suspension and a muted yet muscular powertrain all do their thing underneath. The atmosphere is special and rarefied. That's what an S-Class needs to be and that's what is happening in our $299,000 (as tested) S450L.

The same more-or-less applies up front, as the same trim, leather, wood and technology surrounds the driver and passenger. The spectre of the car that is surely The Car of the Last Decade – Tesla's Model S – is evident in the portrait touchscreen and sparse, almost wallflower dashboard design and layout. No big imposing architectures here.

Yet, while the American upstart actually takes stuff away, the S-Class packs the cabin with subtle features that – like when the planes stopped flying last year and the birdsong subsequently returned – only become obvious once the cabin's design simplicity clears all the white noise for you to be in a better frame of mind to enjoy them.   

Take the haptic interface, for example, as it is perhaps the best we've experienced; the sense of well-being garnered from the cumulative effects of profound seat comfort (the massaging function was never switched off), cocooning micro climate environmental control, orchestral levels of audio entertainment and the theatre of light and vision performed by the two available screens; it is an automotive experience like no other. And the eye-tracking 3D-effect navigation set within the electronic instrumentation. No need for cinematic glasses to get the effect. The driving position itself, by the way, is also first class.

Room to stretch and grow for sure, and in every direction. But room for improvement? You betcha.

Your tester had a headache after a little while staring at that woozy 3D map. The central vents – four at the front, two in the rear – look and feel cheap, leaving us mentally redesigning them; they are frightfully out of place here; the carryover column-stalk auto lever should have been binned in 2005. And, even though the digital instruments have a number of options, none are elegant enough for the S-Class. That's an especially subjective criticism, clearly, but one that – in the context of classic Mercedes luxury sedan contenders – is justified given how timeless the Bruno Sacco era of Daimler design was. Look him up, kids.

Still, after a couple of hours behind the wheel, with our senses reset to calm, it is obvious that the S-Class cabin is a unique and wonderful place – as it should be at a cool quarter-of-a-million dollars.

Job done.

PS At 550 litres (20L more than before), the boot is massive and luxurious enough to sleep in.

The Megane RS Trophy’s cabin carries over some of the design cues from the exterior. It looks and feels like a hot hatch should.

There’s a lovely part-Nappa leather, part-Alcantara steering wheel with paddle shifters and a ‘centre line’ marker - but some may lament the lack of a flat-bottom to the wheel, which is a current trend in the “trust me I’m actually very sporty” breed of cars.

The manually adjustable seats are very supportive though they are a bit firm, so those wishing for ultimate comfort over long distance trips might be left wanting. But there is good adjustment to the seats, and they’re heated, too.

There are some nice elements to the cabin including soft plastics on the dashboard, but the lower plastics - below the eye-line - are quite hard and not very pleasant. However, the inclusion of ambient lighting does distract from that, and add a bit of flair to the cabin.

The portrait-style media screen is fine most of the time, though it does take some learning. The menus aren’t as intuitive as you might hope, with a mix of on-screen buttons and off-screen touchpad-style controls that can be difficult to hit when you’re driving. We also had a couple of instances of glitching while using Apple CarPlay and Android Auto smartphone mirroring.

Storage is okay. There are shallow cupholders between the seats, a covered centre console bin, as well as a storage section in front of the gear selector that’s big enough for a wallet and phone, and bottle holders in the doors. 

In the rear seat there’s enough space for someone my size (182cm) to sit behind their own driving position, albeit with limited knee room and toe room. Headroom is good, and there are dual ISOFIX child-seat anchor points and three top-tethers for baby seats.

You’ll find a pair of small door pockets, two map pockets, and rear-seat directional air vents, which is nice. There’s a flip-down arm-rest with cupholders, too, and unlike some other high-price hatches with ambient lighting up front, the Megane gets LED light strips on its rear doors, too. 

The boot space is good in the Megane RS Trophy, with luggage capacity claimed at a healthy 434 litres. On test, the car fit all three CarsGuide suitcases (124L, 95L and 36L) with room to spare. Speaking of spare (ahem), there isn’t one: it comes with a repair kit and tyre pressure monitoring, but no spare wheel of any kind. 

The Renault Megane RS Trophy has a list price of $52,990 for the six-speed manual, or $55,900 for the six-speed dual-clutch auto model, as tested here. Those costs are RRP/MSRP, and don't include on-roads. 

Standard equipment for this range-topping ‘regular’ RS model includes 19-inch ‘Jerez’ alloy wheels with Bridgestone Potenza S001 tyres, an active valve exhaust system, Brembo brakes, LED headlights with LED daytime running lights, rear fog lights, front/rear/side parking sensors, semi-autonomous parking system, reversing camera, auto locking, smart key card and push-button start, and steering column-mounted paddle shifters.

There’s also auto headlights, auto wipers, dual zone climate control, an auto dimming rearview mirror, heated front seats with manual adjustment, a nine-speaker Bose sound system with subwoofer and amplifier, an 8.7-inch touchscreen media system with aux port, 2x USB ports, Bluetooth phone and audio, Apple CarPlay and Android Auto, sat nav, the brand’s RS Monitor track timing software, and a 7.0-inch TFT colour screen for the driver with configurable modes and digital speedo.

You can find a run down of the safety tech and equipment fitted in the safety section below.

Options available include an electric sunroof ($1990), and there is also the choice of a few metallic paint colours: Diamond Black and Pearl White metallic are both $800, while the Signature Metallic Paint colours - Liquid Yellow and Orange Tonic as you see here - are $1000. Only Glacier White will cost you no extra. 

Wondering where it sits among its closest rivals? If you’re thinking about a Ford Focus ST (from $44,690 - manual or auto), Hyundai i30 N (from $41,400 - manual only), the outgoing VW Golf GTI (from $46,690 - auto only), or the mighty Honda Civic Type R (from $51,990 - manual only) the Megane RS Trophy is expensive. Only the VW Golf R Final Edition ($57,990 - auto only) is dearer… unless you’re thinking of comparing to the likes of a Mercedes-AMG A35 ($69,300).

Where are the V8s?

Right now, the only W223 you can buy is powered by an all-new 2999cc 3.0-litre in-line direct-injection six-cylinder turbo petrol engine dubbed the M256, complete with double overhead cams, an electric compressor intercooler and assistance from a 48-volt mild hybrid system and integrated starter-generator, adding 16kW and 250Nm to the 270kW of power at 6100rpm and 500Nm of torque from 1600-4500rpm.

The 9G-Tronic torque-converter automatic transmission and 4Matic all-wheel drive system combination is a first for the S-Class in Australia.

Top speed is limited to 250km/h, while the 0-100km/h sprint-time takes just 5.1 seconds in both models. Impressive for a two-tonne-plus luxury limo.

Engine specs matter if you’re talking about performance hatchbacks, and the Megane RS Trophy is no exception.

It has a 1.8-litre four-cylinder turbo-petrol engine that punches hard for its size, with 221kW of power (at 6000rpm) and 420Nm of torque (at 3200rpm). That’s for the six-speed dual-clutch automatic transmission, as was fitted to our test car. If you buy the six-speed manual, you miss out on a bit of grunt - it has 400Nm (at 3200rpm) and the same peak power.

In auto spec the RS Trophy “300” offers higher figure vs the Sport and Cup “280” models (205kW/390Nm), and more engine performance per litre of capacity than the Focus ST (2.3-litre: 206kW/420Nm), Golf GTI (2.0-litre: 180kW/370Nm; TCR 2.0-litre: 213kW/400Nm), and even the Golf R (2.0-litre: 213kW/380Nm). 

All Megane RS models are front-wheel drive (FWD/2WD) and no Megane RS is all-wheel drive (AWD). The Trophy and Cup models both get 4Control four-wheel steering, which is an interesting aspect of the drive experience. More on that below. 

There are multiple drive modes to choose from, including Comfort, Neutral, Sport, Race and the configurable Perso mode. These can alter engine, transmission, throttle, traction control, exhaust noise, fake engine sound and steering sharpness - but not suspension, because the dampers aren’t adaptive units. 

With the aid of the mild-hybrid system, the S450 returned a combined average of an impressive 8.2 litres per 100km, which translates to 187 grams of carbon dioxide emissions per kilometre. 95 RON premium unleaded (or higher) is recommended. In the urban run it consumes 11.3L/100km (11.5 for S450L), and just 6.4L/100km (6.5 for S450L) in the extra-urban result.

At 76 litres, the fuel tank will allow a combined average range of about 927km between refills.

The claimed official combined fuel consumption for the Megane RS Trophy is 8.0 litres per 100 kilometres. That’s for the EDC auto model as tested. The manual is said to use 8.3L/100km.

You might achieve that if you drive gently, though over my testing - which incorporated hundreds of kilometres of highway and country road driving, as well as a few spirited stints and some urban snarls - I saw a return of 10.8L/100km at the pump.

The Megane RS requires 98RON premium unleaded, and the fuel tank capacity is 50 litres. 

In former times, as the Germans say, a ‘450' on the boot indicated V8 power. In the W116 S-Class era it was one of the world's most evocative badges when ‘SEL' was also attached.

As mentioned earlier, though, it's the M256 3.0-litre turbo-petrol with a 48-volt ‘mild hybrid' electrical system that's doing the driving, to all four wheels. The real V8 W223 will probably surface later this year or in early 2022 with the S580L flagship. Bring it on.

This is not to say that S450 isn't good enough. With that electrified assistance, the blown straight six is smooth and swift off the line and rapid as the auto seamlessly steps up through all nine gears. Because it's so hushed and refined, it doesn't feel 5.1s to 100 clicks quick, but watching the speedo says otherwise – acceleration is assertive and strong right up way past the legal speed limit.

All that's missing is the burbling soundtrack of a classic Benz bent-eight. Oh well. Outstanding economy is a price we're literally willing to pay in lieu.

Even more impressive is the S450's ability to hustle along mountain roads like an overgrown sports sedan.

Now, for Australia, all S-Classes are fitted standard with an adaptive ‘Airmatic' air-suspension set-up, including air springs and self-levelling tech. In Comfort up to 60km/h, the ride height can be raised by 30mm, or lowered by 10mm under the standard 130mm baseline in Sport at any velocity, while in Sport+ it falls another 17mm.

With that in mind, yes, the standard air suspension performs a magnificent job smothering out most surface imperfections around town. Yet its real other party trick is to tighten up the chassis when corners get interesting and Sport mode is selected. Aided by progressively weighted and reassuringly responsive steering, the Mercedes tips into turns with precision and poise, slicing through with virtually no discernible body lean or understeer.

Now, we're not talking a leisurely drive on rural highways here, but Healesville's famous Chum Creek Road, where even a Porsche Cayman would feel like it's had a strenuous dynamic workout. The S-Class can be hurried along with confidence and finesse, displaying outstanding handling and roadholding for a 5.2-metre long limo. And the fact that the ride quality only suffers marginally when the red horns are out is all the more remarkable.

Back in the cut-and-thrust of inner-city peak-hour traffic, the Benz in Comfort mode continued to reveal its driver-orientated yet passenger-focused twin-personalities, zipping in and out of gaps while remaining comfy and composed inside.

Only when parking in tight spots are you truly aware that the W223 is longer than a Mazda CX-9. The optional four-wheel-steering system is claimed to slash the turning circle to A-Class hatchback levels. 10.9 metres is the claim.

The 2021 S-Class never ceases to amaze and delight.

The Megane RS Trophy has the ingredients to be an all-time legendary hot hatch, but they don’t work together well enough for it to be a truly great car to drive.

That is, they don’t work together on public roads. I didn’t get a chance to sample the RS Trophy at the track, and I’m sure that may well alter some of my opinions. But this was a review focused around everyday driving first and foremost, because - unless you’ve got quite a fleet of cars - you’ll be spending a lot of time in mundane motoring in your Megane RS, too.

Other hot hatches in the segment manage to combine big power and torque with immense traction and steering prowess. The Megane RS used to, as well.

But this new version seemingly has some issues harnessing the grunt, and the 4Control four-wheel steering system simply isn’t as rewarding as it should be.

I had several instances where the traction on slippery surfaces was lacking, while even in the dry I noticed distinct torque steer and the Bridgestone tyres struggled to cope under hard acceleration. That’s despite the fact the Trophy gets a mechanical LSD.  

Further, that four-wheel steering actually makes it pretty hard to judge the behaviour of the car at times, with an artificial feel to it that just doesn’t do it justice. There will be some who say that the four-wheel steering - which can angle in the rear tyres to help you pivot in corners more adeptly - is excellent. But I’m not one of them. I really found it hard to predict this car’s behaviour. I never really gelled with it.

At the very least there’s a non-interventional lane keeping assist system, which emits a pulsing sound through the speakers rather than actively vibrating or adjusting the steering. 

The ride is unapologetic in its firmness – although, if you’re across the history of RS Megane models, that is to be expected for a Trophy chassis. It can be tiring on longer road trips especially if the surface isn’t great.

While it is extremely fast in a straight line - 0-100km/h is claimed at just 5.7 seconds - it wasn’t as quick through corners as I was expecting it might be, and that comes down to its four-wheel steering mostly, along with a lack of usable traction at times. It simply isn’t as connected to the road as the previous RSs have been. 

It was also a bit laggy then lurchy at lower speeds when taking off from a standstill, such is the nature of the dual-clutch in stop-start situations. 

To put it bluntly, I didn’t enjoy this car anywhere near as much as I thought I might. It just isn’t as pure a driving machine as I’ve come to expect from the RS brand. Perhaps I should aim to try it on a track!

The Renault Megane has not been awarded an ANCAP crash test rating, but the regular (non-RS) model scored five stars against EuroNCAP criteria back in 2015.

The RS Trophy (manual or automatic) comes fitted with adaptive cruise control with speed limiter, auto emergency braking (AEB) at speeds between 30km/h and 140km/h, blind spot monitoring, lane departure warning with audio alert, reversing camera, surround parking sensors and semi-autonomous parking.

Missing is rear cross-traffic alert, front cross-traffic alert, rear AEB, pedestrian detection and cyclist detection. 

Unlike many luxury brands that persist with a sub-par three-year warranty, Mercedes-Benz offers a five-year/unlimited kilometre warranty.

Intervals are every year or 25,000km, with a capped price service plan starting at $800 for the first year, $1200 for the second year and $1400 for the third year, totalling $3400. Alternatively, there is a Service Plan starting at $2700 for the first three years (saving $700 from the normal capped-price service plan), $3600 for four years and $5400 for five years.

The Renault Megane RS range is covered by a five-year/unlimited kilometre warranty, which adds some peace of mind for owners.

Further, the service intervals are generous, at 12 months/20,000km - though the brand states the Megane RS is actually “subject to adaptive servicing requirements” as the oil condition sensor may trigger a service check requirement prior to the standard intervals.

Unlike other Renault models with a five-year capped price servicing plan, the Megane RS is only covered for three years/60,000km. The service costs for the EDC dual-clutch auto models are higher than the manual versions, due to replacement transmission oil being needed (adding $400 to the first service). 

The costs for the first three services are: $799 (12 months/20,000km); $299 (24 months/40,000km); $399 (36 months/60,000km). Consumables beyond those service intervals include: every 24 months or 20,000km - air filter replacement ($49) and pollen filter replacement ($63); every 48 months or 60,000km - accessory belt replacement ($306). Spark plugs are included at no cost, due every 36 months/60,000km.

The car is backed for up to four years of roadside assistance when serviced within the Renault dealership/service network.
