Mercedes-Benz S-Class vs Maserati MC20

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.

With a 320km/h-plus top speed and the ability to get from rest to 100km/h in under three seconds, there’s no doubting the MC20 meets or exceeds its performance brief. But when you’re paying these prices, there must be more than just the measurable stuff going on.

And there is. The MC20 brings a big dollop of purity to the ranks of current supercars, doing away with all-wheel drive and hybrid tech and relying instead on and old-school approach in terms of handling and overall feel.

Anybody who wants to argue that call has plenty of alternatives to the MC20 from other manufacturers, and for some of us, that less-is-more thing will ring true.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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.

Perhaps the most striking thing about the MC20’s design is that it’s so restrained. You won’t find wings, vents, fins and diffusers all over the car, but rather an overall shape that creates downforce, rather than that job falling to tacked on additions.

And, like any modern supercar worth its salt, the MC20 is based around a carbon-fibre tub for rigidity and low weight. From that tub structure are hung aluminium front and rear subframes which, in turn, mount the suspension and other mechanical bits.

The wind tunnel still got a huge workout in the car’s development, of course, but the aim was to integrate the downforce-inducing elements rather than having them demanding your optical attention.

As a result, the whole car is an upside-down wing, if you want to simplify it. But a very pretty upside-down wing.

This gives the MC20 a smooth, sleek look that stands it apart from the rent-a-racer crowd and supports the theory that sometimes, less is, indeed, more.

Some of the detailing is lovely, too. The vents cut into the Perspex rear windscreen form Maserati’s trademark trident shape, there’s lots of visible carbon-fibre inside the door jambs, there’s lashings of Alcantara inside and the two-tone body kit breaks up the shape perfectly.

Elements we’re not so sure about include the 'Park' button mounted way down low under the dashboard, and the swing-up, scissor-type doors, which, if your more than about 180cm tall, still require you to duck under them.

On the upside, the carbon-and-leather steering wheel with its integrated controls is gorgeous to hold and gaze at.

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.

Although the MC20 has a front and rear luggage compartment, they’re both small enough to be pretty much useless. This is a shame, because as a long-weekend getaway car, the Maserati otherwise makes a strong case for itself.

The other area that suffers for the car’s art is the interior practicality. While the driving position is great and the pedals and wheel relationship is spot on, when it comes to storing anything, you’re on your own. Best the MC20 can offer is a single cupholder at the rear of the central tunnel.

The mid-engined layout also means there’s precious little vision through the back window. To counter that, Maserati has fitted the MC20 with an interior rear-view mirror that can act as a conventional mirror (you can still see only the engine) or as a screen for the rear-mounted camera.

The catch is the image projected to the 'mirror' lacks depth of field and forces the driver to refocus on the image rather than simply glance at it.

Maserati has followed the lead of many a high-end carmaker by using the options list to ramp up the profitability of the MC20. Of course, that’s after the MSRP of $438,000 has been dealt with by your accountant.

The point is that you kind of need to suspend disbelief when it comes to supercars and their value-for-money credentials. By any sane, conventional measure, they’re seriously over-priced, but within its peer group, the Maserati is neither the cheapest nor the most expensive way to go this fast.

But back to those options: Again, it’s all a case of throwing away what you think you know, because there are several options for the Maserati that cost more than a good, brand-new hatchback.

The carbon-fibre engine cover alone will cost you a staggering $13,164, and according to Maserati management, it’s a popular option.

Then, there are the carbon-fibre brakes which not only cost $28,961, but if you want the yellow-painted calipers, that’ll be another $2962.

The hydraulic front-lifter which allows you to deal with driveways and speed humps is a monstrous $8721, but at least there’s some engineering in that. Unlike the black-roof option which is, er, a black roof at $10,202. And the external carbon-fibre kit? A cool $92,806!

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.

Previous generations of Maseratis borrowed Ferrari (both brands were once part of the extended Fiat Chrysler family) technology for their drivelines in a deal that allowed both brands to share the cost of development.

And since having a Ferrari-built engine in your car was never seen as a sale hindrance, it was a sweet deal for Maserati. But when Ferrari was spun off and became a publicly-owned company in 2016, Maserati’s supply of engines dried up.

The solution was to take engine design in-house and the twin-turbocharged 3.0-litre V6 in the MC20 is one of the first fruits of that.

While it’s undoubtedly a high-tech powerplant, in other respects it’s fairly conventional. Maserati, for instance, has a long history with the V6 layout, and there’s no hybrid element to the driveline. Nor is there a hybrid option.

Maserati claims the V6 is the world’s most powerful six-cylinder production-car engine and, with no less than 463kW at 7500rpm and 730Nm between 3000 and 5500rpm, that’s a credible statement.

Technical details that you won’t see on most road cars include a dry-sump lubrication system (where the engine oil lives in a remote tank rather than the hot sump of the engine itself) and a sophisticated fuel injection system with two injectors per cylinder.

The real trick, however, is an ignition system with two spark plugs per cylinder. There are also effectively two combustion chambers, the first ensuring multiple flame fronts to achieve a more complete burn of the fuel in the main combustion chamber.

The rest of the driveline is similarly aimed at the purists out there; the transmission is an eight-speed dual-clutch, driving not all four wheels, but only the rears through a mechanical limited-slip differential.

Selectable drive modes from GT (the default setting) through to 'Wet', 'Sport', 'Corsa' (Track) and 'ESC Off' tailor the shift points, throttle sensitivity and suspension behaviour, but still allow for full engine power.

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.

Fuel economy is probably not going to be top of mind for most MC20 buyers, but the official combined figure of 11.6 litres per 100km is still pretty greedy by 2022 standards.

Balanced against the available performance, however, and an engine making more than 600 old-fashioned horsepower with that combined fuel-economy number is still cause to reflect on modern technology and efficiency.

The MC20 has a 60-litre fuel tank, making it a handy cross-country car for weekends away.

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.

Here’s where your half-a-million bucks has gone.

The MC20’s acceleration is absolutely shattering and is all the more amazing for the fact the car uses neither all-wheel drive grip nor hybrid torque to achieve its sprinting abilities.

While the V6 is not the most sonorous of powerplants, it does manage to sound high-end and pretty sophisticated and it’s never as shouty as some of its opposition which seem to confuse decibels with kiloWatts.

While the sheer thrust confirms the existence of two turbochargers, the lack of lag (or throttle delay) and the ability to charge into the rev limiter in the lower gears does not.

Even though power peaks at 6500rpm (as with many a modern turbo motor) the MC20 will happily smash on to the redline at 8000rpm; sometimes too happily if you don’t have your finger over the upshift paddle. As with other good modern turbocharged units, this one doesn’t actually feel overtly turbocharged.

The transmission shifts relatively smoothly in GT mode, but as you crank up the mode selector to Sport, the shifts become very fast with an accompanying jolt through the backrest as each gear clicks home. The shifting process is fairly foolproof, although you do get full over-ride, so you need to pay attention.

Both the cars we were able to sample at Philip Island were sporting the optional carbon-ceramic braking package, and one was also fitted with the optional 'birdcage' alloy wheels which are lighter.

Each of them needed a firm shove on the pedal to slow things down, but it’s true the lighter wheels seem to be worth their almost-$3000 ask as that car required less leg-pressure for the same result.

The lack of a hybrid element to the driveline, as well as the rear-drive layout, suggests a degree of purity of purpose in the car’s design. And that’s backed up by its behaviour in the first corner.

Fundamentally, instead of just hurling it at an apex and allowing the electronics to sort it all out for you, the Maserati requires a more 'classical' technique if it’s to really shine.

It doesn’t, for instance, reward trail-braking (where you continue to brake once you’ve turned into a corner) and would much prefer you get your braking over and done with before applying any meaningful steering lock.

Ignore this, and the rear weight bias of the mid-engined layout can see the car try to yaw, with the rear end becoming light and the vehicle over-rotating (which is a spin, to you and I).

Similarly, getting on the power before you’ve actually got the MC20 turned, can unload the front end and send the front wheels ploughing (ploughing is an exaggeration, but at the speeds we’re dealing with here, even a small degree is a big deal) towards the outside of the turn.

Ultimately, then, the technique becomes a text-book case of brake, turn and then power out, at which point the MC20 reveals itself to be huge fun and incredibly fast. The only thing to deal with then is the knowledge that whatever happens next is going to happen extremely quickly.

Neither ANCAP nor Euro NCAP have tested the MC20 for crash safety, so we can’t give it a star rating.

But the lack of standard safety gear such as rear-cross traffic alert and blind-spot monitoring (it’s optional at $2797) can’t go unmentioned. That’s especially concerning when you consider the mid-engined layout makes for very poor rear visibility.

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.

High-end cars often disappoint on the details, and the Maserati is no different here, offering just a three-year factory warranty (albeit with unlimited kilometres).

That trails even the most humble commuter cars these days, and suggests there’s still a degree of indifference from some carmakers. And, possibly, their customers.

There is, however, the option of fixed-price servicing for the MC20 with the first three years’ worth of servicing costing $4000.

Scheduled services are every 15,000km or 12 months, whichever comes first.
