Mercedes-Benz S-Class vs Range Rover Sport

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.

Range Rover proudly calls it its “most dynamic” model ever, and based on our first experience that’s most definitely true. Its ability to be genuinely exciting to drive on a race track is nothing short of remarkable for a brand whose history is all about off-road prowess.

On the road it shines just as brightly, with its potent engine and state-of-the-art suspension system working in unison to make for a stunningly dynamic large and luxurious SUV. And then, if you need to cut across a field or scramble up a slippery hill, it will do that too.

Range Rover’s claims of ‘breadth of capability’ is apt but arguably an understatement. I’d stop short of calling the Sport SV the obvious class-leader in the high-end, high-performance SUV market because it’s up against some seriously impressive rivals, but the Range Rover offers a broader range of ability than any of its competitors.

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.

Range Rover is a brand synonymous with big, imposing and off-road capable SUVs, not dynamic and sporty vehicles. But in recent years the Evoque and Velar have added a new layer of style and a sleekness to the brand’s reputation.

The latest generation Sport is still a big and imposing two-tonne SUV, but it’s also definitely sportier to look at and the SV changes only add to that.

It only takes a moment looking at it and it’s clear this is an SUV that means business. The 23-inch wheels fill out the guards, the air-suspension can lower the body to the ground and the aerodynamic package, including the front splitter, make for a purposeful look.

The carbon-fibre bonnet can be finished with the centre section exposed, showing off the weave of the fibres, which is a nice touch, although fake vents on the bonnet and front fenders are a bit disappointing.

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.

There are two stand-out features in the cabin, beyond the standard high-level of luxury you expect from a Range Rover Sport. 

The first is the SV-specific steering wheel with illuminated paddles, which feels solid in your hands. But the second is by far the most interesting, the so-called Body and Soul Seats (BASS), which Range Rover has developed in conjunction with Coventry University.

Available with either genuine leather or ‘ultra fabric’ and a 3D-print knit trim, the seats look great on the outside but it’s what’s inside them that’s special.

There are four audio transducers integrated into the seat back which can vibrate to the beat of whatever audio track you’re listening to. The system uses AI to detect the lower frequencies and then work out which beats to transmit.

This is technology used by musicians, Coldplay’s Chris Martin reportedly wears transducers integrated into a vest when he performs, but Range Rover is confident it will add to the ownership experience.

It’s certainly an interesting technology and a demonstration across different music genres highlights the way the system adapts to individual songs, but it’s hard not to feel like this is more of a gimmick than something an owner will use every day. 

If you don’t like listening to music with it, the Body and Soul Seats also work with a ‘Wellness’ setting that features six audio pieces (designed by Coventry University musicians) - calm, soothe, serene, cool, tonic and invigorate.

It’s probably what you need to help settle your heart rate after you unleash the full performance potential of the Sport SV.

In the back seat there’s none of this technology but they do feature heating and ventilation as well as power recline functions. There’s also four-zone climate control, so every occupant can be comfortable.

To be blunt, the Range Rover Sport SV is one of those vehicles that if you have to ask, you can’t afford. Particularly in this case, as the model has launched in a single specification level, the Sport SV Edition One, which is priced from $360,800, plus on-road costs.

That puts it into the same financial category as the likes of the Aston Martin DBX ($356,512), Porsche Cayenne Turbo GT Coupe ($364,700) and Lamborghini Urus ($409,744) - especially when we discuss some of the pricier options.

For that price the Sport SV Edition One comes with exclusive branding on the front splitter, centre console, treadplates and puddle lamps as well as a raft of standard features likely to carry-over to the 2025 model year version.

These include carbon-fibre badges, forged 23-inch alloy wheels, digital LED headlights, a carbon-fibre bonnet, 16-way electronically adjustable front seats, Meridian 'Signature' sound system, 13.1-inch multimedia touchscreen, Apple CarPlay and Android Auto and newly developed ‘Body and Soul Seats’ (more on those later).

But if you’re feeling really sporty, you can upgrade your Sport SV with lightweight carbon fibre wheels and carbon ceramic brakes.

These will cost you a staggering $16,130 and $13,500, respectively, but the wheels measure 23-inches and are the largest fitted to a production car (and are also Australian-made by Carbon Revolution in Geelong).

Unfortunately, for now at least, this is all a moot point because Range Rover Australia has already invited and sold all examples of the Sport SV Edition One, so you'll need to be patient and wait until at least 2025 to have the option to buy one.

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.

Sadly the wonderfully evocative supercharged V8 engine from the previous generation Range Rover Sport SVR is gone.

But, thankfully, in its place is a more powerful engine that’s exclusive to the Sport SV in the Jaguar Land Rover family.

It’s a 4.4-litre twin-turbo V8 petrol engine with mild-hybrid assistance, which is actually built by BMW and based on the same powertrain as you’ll find in the M5, albeit with some specific Range Rover elements for more off-road capability.

It’s also more powerful than the old supercharged V8, making an impressive 467kW of power and 750Nm of torque, which is a 44kW and 50Nm improvement over the old engine.

It’s paired to an eight-speed automatic transmission, again with a specific SV calibration for improved performance. 

And, of course, being a Land Rover, it’s also got a four-wheel drive system with full off-road systems as well as an active locking differential.

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.

Despite all the extra power, thanks to the mild-hybrid system it’s more fuel efficient and produces less emissions than the old 5.0-litre V8.

Still, it’s all relative, and as you’d expect from a twin-turbo V8 SUV it’s still thirsty and uses 11.7-12.5-litres per 100km, based on European specifications.

The mild hybrid system uses a crank-integrated starter generator instead of a conventional alternator, providing a boost of up to 20kW and 175Nm of electrical power when needed, with the energy captured during braking and stored in a 48-volt lithium-ion battery.

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.

Before driving the Sport SV you need to understand its highly complex suspension system that allows it to be so dynamically capable. Range Rover calls it a '6D Dynamic' system, because it can control the car left and right, up and down and corner to corner. 

To achieve this the system uses a combination of hydraulic interlinked dampers, height-adjustable air springs and pitch control, which makes it a semi-active suspension set-up similar to the set-up Formula 1 race cars used to boast. 

This allows the Sport SV to sit between 10-25mm lower than the other Sport models and with its clever suspension can actually sit flatter in the corner with less pitch and roll - which is the traditional enemy of high-riding SUVs when it comes to handling.

But the suspension is only part of the story, with the intelligent all-wheel drive, rear-wheel steering, torque vectoring and the active locking rear diff all combining to produce an SUV with incredibly impressive dynamic capability.

Put simply, there’s never been a Range Rover that deserved to be driven on a racetrack. The Sport SV changes that, and thankfully the company let us loose on the challenging Portimao circuit in Portugal to put the SV through its paces.

Range Rover management was quick to stress it doesn’t expect the Sport SV to be a race track regular for its owners, but driving it on track did highlight the extreme potential it offers. 

With such a powerful engine it should come as no surprise that the Sport SV hauled down the straight, hitting 233km/h at the end of the long front straight, but with speed still rising which suggests its 290km/h claimed top speed is accurate.

Even from those speeds and with 2560kg of SUV to slow down, with the carbon ceramic brakes it was no trouble whatsoever. Instead the braking was strong and consistent across multiple laps. 

The steering is the particular highlight, with the rear-wheel steering helping to turn the Sport SV sharper and more quickly than a big SUV like this should. 

But while it impressed on the circuit, we also experienced it on some great winding rural roads across Portugal and this is where it shone even more brightly.

This is an SUV that you’ll genuinely enjoy driving with its ability to carve through corners and blast down anything resembling straight road.

But to ensure it lives up to the Land Rover badge on the front, we also drove it off-road. Nothing too serious at first, just muddy ruts, across some water and over some rocks.

But then we were guided through a course that showed off its articulation potential, which is far greater than the average owner will ever need. 

However, to achieve this Range Rover removed the carbon-fibre front splitter, so it’s not the most off-road friendly model the brand offers.

The Sport SV comes generously equipped with safety gear, as you’d expect at this price point. There’s all the usual passive safety, including airbag coverage for all occupants, and plenty of active safety including adaptive cruise control with steering assist, remote park assist and 3D surround cameras - which are used for off-roading as well as parking.

As with the rest of the Range Rover Sport range, it has been awarded a maximum five-star rating from safety agency, ANCAP.

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.

If you’re worrying about servicing costs, you’re probably shopping at the wrong end of the market, but as with the range-topping Range Rover model the price of the car is expected to include servicing for the first five years and roadside assistance for the same period.

It’s also covered by a five-year, unlimited kilometre warranty.

As with all Range Rovers the car will tell you when it needs a service depending on driving conditions. For example, if you hit the track or go off-roading it will likely need a visit quicker than if you're just commuting to and from work.
