Mercedes-Benz S-Class vs Volkswagen Arteon

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.

The value, driving dynamics and appearance are on point for a premium play here. If you can forgo the badge snobbery attached to the German big three, then you'll find lots to like about Volkswagen's Arteon.

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.

It's really all about the looks here, and while the Shooting Brake is particularly handsome, the regular Arteon looks premium and polished, too.

VW tells us injecting a bit of sportiness was a key aim here, both inside and outside, and that's particularly true of the R-Line model, which rides on bigger 20-inch alloys, compared to the 19s on the Elegance, with their own bespoke design.

The body styling is more aggressive, too, but both trims get lashings of chrome along the body work, and a sleek, swept-back style that looks more premium than overtly sporty.

In the cabin, though, you can see that this is an important car to VW. The touchpoints are almost all soft to the touch, and it's both understated and tech-saturated at the same time, including the swipe-to-adjust function for the stereo and climate, with new touch-sensitive sections added to the centre console and steering wheel.

It feels, dare we say it, premium. Which is likely exactly what VW was going for...

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.

Interestingly, both body styles share near identical dimensions, with the Arteon stretching 4866mm in length, 1871 in width, and 1442mm in height (or 1447mm for the Shooting Brake).

Those numbers translate to a seriously spacious and practical cabin space, with an acreage of room for backseat riders. Sitting behind my own 175cm driving position, I had heaps of space between my knees and the seat in front, and even with the sloping roofline, plenty of headroom, too.

You'll find two cupholders in a pull-down divider that separates the back seat, and a bottle holder in each the four doors. Backseat riders also get their own air vents with temp controls, as well as USB connections, and phone or tablet pockets on the rear of each front seat.

Up front, the theme of space continues, with storage and cubbies sprinkled throughout the cabin, as well as USB-C connections for your phone or devices.

All that space means a sizeable boot area, too, with the Arteon serving up 563L with the rear seats in place, and 1557L with the back pews folded. The Shooting Brake ups those numbers - thought not any as much as you might think - to 565L and 1632L.

The Arteon carries an unsurprisingly premium price tag in the VW family, but it can still be cheaper than an entry-level equivalent from some of the German premium brands.

Or, in the words of VW, the Arteon "challenges the luxury car makers without becoming one ourselves."

And you do get a lot of stuff. In fact, a panoramic sunroof, and some metallic paints, are the only cost options here.

The range is offered in 140TSI Elegance ($61,740 Liftback, $63,740 Shooting Brake) and 206TSI R-Line trims ($68,740/$70,740), and the former is offered with VW's Virtual Cockpit digital instrument cluster, along with a head-up display and a central 9.2-inch touchscreen that pairs wirelessly with your mobile phone.

Outside, you get 19-inch alloy wheels and full LED headlights and tail-lights. Inside, you'll find ambient interior lighting, multi-zone climate control, keyless entry and push-start ignition, as well as full leather interior trim with heated and ventilated front seats.

Also worth calling our here are the digital buttons on the dash or steering that control everything from the stereo to the climate, and work a bit like a mobile might, you can swipe left or right to control the volume or switch tracks, or change the temperature.

The R-Line model is the sportier-feeling option, and adds 'carbon' leather interior trim with bespoke bucket-style sports seats, 20-inch alloy wheels, and a more aggressive set of R-Line bodywork.

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.

There are two drivetrains on offer here — the 140TSI with front-wheel drive in the Elegance, or the 206TSI with all-wheel drive in the R-Line.

The former's 2.0-litre turbo-petrol produces 140kW and 320Nm, which is enough for a sprint to 100km/h in around 7.9 seconds.

But the lust-worthy engine tune is definitely the R-Line, in which the 2.0-litre turbo-petrol ups the grunt to 206kW and 400Nm, and drops the sprint time to a brisk 5.5 seconds.

Both pair with VW's seven-speed DSG automatic.

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.

Volkswagen says the Arteon Elegance will need 6.2L per hundred kilometres on the combined cycle, and will emit 142g/km of C02. The R-Line needs 7.7L/100km on the same cycle, with emissions pegged at 177g/km.

The Arteon is fitted with a 66-litre tank, and a PPF or petrol particulate filter, which strips some of the nasties out of the vehicle's emissions. But, VW says, it's “very important" that you only fill your Arteon with premium feel (95RON for the Elegance, 98RON for the R-Line) or you risk shortening the life of the PPF.

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.

Full disclosure: we only spent time behind the wheel off the R-Line variant for this test, but even still, I feel pretty comfortable suggesting that it's the punchy powertrain you want.

Surely the very first hurdle any company hoping to play with the premium-brand big boys must clear is that of easy, effortless momentum? It's difficult to feel like you've made the premium choice when you're engine is straining and striving under acceleration, right?

And on this, the Arteon R-Line shines, with plenty of power underfoot whenever you need it, and a delivery style which means you rarely, if ever, fall into a hole waiting for the power to arrive.

For mine, the suspension might be a touch too firm for those seeking a truly wafting drive experience. For the record, it doesn't bother me — I always prefer to know what's happening underneath the tyres than be entirely removed from the experience — but a result of this sporty-feeling ride is the occasional registering of bigger bumps and road imperfections in the cabin.

The flip side of the firm(ish) ride is the ability for the Arteon - in R-Line guise - to swap personalities when you engage its sportier settings. Suddenly there's a snarl to the exhaust that's absent in its comfortable drive modes, and you're left with a vehicle that tempts you to head for a twisting back road to see what it's about.

But in the interests of science we instead headed for the freeway to put the Arteon's autonomous systems through their paces, with the brand promising Level 2 Autonomy on the highway.

While the technology still isn't perfect — some braking can occur when the vehicle's not entirely sure what's happening ahead of it — it's also pretty impressive, taking care of the steering, accelerating and braking for you, at least until you're reminded its time to put your hands back on the wheel.

It's also bloody big, the Arteon, with more space in the cabin - and especially the backseat - than you might be thinking. If you have kids, they'll be positively lost back there. But if you cart adults on the regular, then you'll hear no complaints.

Essentially, if VW makes it, the Arteon gets it. Think front, side, full-length curtain and driver's knee airbags, as well as VW's complete IQ.Drive safety suite, which includes a Fatigue Detection system, AEB with pedestrian detection, Park Assist, parking sensors, rear traffic assist, lane change assist, adaptive cruise control with lane guidance - which is essentially a level 2 autonomous system for highways - and an around view monitor.

The new model is yet to be crash-tested, but the last model scored a five-star rating in 2017.

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 Arteon is covered by VW's five-year, unlimited-kilometre warranty, and will require servicing every 12 months or 15,000kms. It will also get VW's capped price servicing offer.
