Mercedes-Benz S-Class vs Mercedes-Benz Sprinter

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.

Given the original Sprinter was released in 1995, it’s not surprising the current third-generation model feels like it’s benefitted greatly from decades of continuous refinement. Although the list price difference between our test vehicle and its closest Chinese rival is substantial, the 417 MWB Panel Van is hard to fault in terms of driver comfort, safety and all-round competence. It really is very good.

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 417 MWB Panel Van rides on a 3665mm wheelbase (the shortest of three Sprinter wheelbases) and is almost 6.0 metres long (5932mm), more than 2.0 metres wide (2020mm) and stands almost 2.4 metres tall (2378mm). Its 12.4 metres kerb-to-kerb turning circle is impressively tight for a vehicle of this length.

It rides on simple and rugged MacPherson strut front suspension, with a robust live axle/leaf-spring arrangement under the tail. Steering is via rack and pinion and it has disc brakes all around.

Look beyond the optional silver metallic paint on our example and there’s extensive use of unpainted dark grey plastic on all the external surfaces where hard-working vans are most prone to wear and tear, including the hubcaps, front/rear bumpers, grille, door-handles/mirror shells and along the sides.

Its work-focused exterior styling is nicely integrated, combined with an equally neat and functional interior design that offers a visually-pleasing combination of patterned fabric seat-facings and hard surfaces that blend different shades of grey with splashes of satin chrome and piano black.

We also like the feel and response of mechanical switches (rather than touchscreen prompts) for adjusting settings like cabin temperature, fan speed and media volume.

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.

With its 2215kg kerb weight and 4100kg GVM, our test vehicle has a sizeable 1885kg payload rating.

It’s also rated to tow up to 2000kg of braked trailer and with its 6100kg GCM (or how it can legally carry and tow at the same time), that means it can tow its maximum trailer weight while hauling its maximum payload to ensure optimum versatility.

The cargo bay, which offers a cave-like 9.0 cubic metres of load volume and internal lighting front and rear, has internal dimensions of 3316mm length (with bulkhead), 1732mm width and 1719mm height.

So, with 1350mm between the rear wheel-housings, it can comfortably fit two standard 1165mm-square Aussie pallets or up to four 1200 x 800mm Euro pallets, held in place by a choice of 10 floor-mounted load-anchorage points.

The cargo bay is accessed through a single kerbside sliding door with a wide 1260mm opening, or symmetrical rear barn-doors with large handles on each pillar to assist operator access.

The barn-doors also have internal storage bins and open to a full 180-degrees to assist forklift and loading dock access. Thoughtfully, their hinge design also holds the doors firmly open at 180 degrees, to minimise the chance of wind gusts slamming them shut with potential injury to the operator.

There’s also plenty of cabin storage starting with two tiers of bins in each door, with the highest being spacious enough to hold large bottles.

There's also a deep shelf on the passenger side lower dash, a large lidded compartment in the central dash-pad and overhead shelves with lockable storage on the passenger side. Plus, the dash offers a total of eight cup/small-bottle holders.

The base cushion of the two-passenger bench seat is also hinged at the front, which allows it to tilt forward and provide access to a large hidden storage area beneath.

A crew of three can travel in relative comfort (for a commercial van that is) thanks to a central seating position that provides a sturdy hoop-handle for support, sufficient knee clearance from the dash even for tall people, and a reasonably flat and spacious floor area.

The cabin also features the latest next-gen 'MBUX' multimedia system with 10.25-inch touchscreen, which for the first time offers wireless connectivity for Apple CarPlay and Android Auto.

There’s also digital radio and enhanced functionality including an optional navigation upgrade with seven years of map updates.

Our test vehicle is the 417CDI MWB (Medium Wheelbase) Panel Van with standard roof height, which comes equipped with a 2.0-litre, four-cylinder, turbo-diesel engine and nine-speed automatic transmission for a list price of $86,018.

Our example is fitted with a couple of factory options, including the 'Cargo Pack' ($2265) which comprises a two-passenger bench seat, solid cabin bulkhead with fixed window and side-entrance assist handle, wooden cargo bay load floor and floor-to-roof wall-trim using 5.0mm-thick wood panelling.

It also has optional 'High-Tech Silver' metallic paint ($2534) which combined with the Cargo Pack raises the total price to $90,817.

In addition to the latest model’s upgraded safety (see Safety) and comfort/convenience (see Design) features, our test vehicle comes standard with 16-inch steel wheels and 235/65 R16C tyres plus a full-size spare, keyless start, steering wheel paddles for manual shifting, multi-function leather steering wheel, three USB-C ports and two 12-volt sockets, side marker lights and heated exterior mirrors.

There’s also daytime running lights, a parking package with reversing camera and front/rear parking sensors, traffic sign assist, tyre pressure monitoring and lots more.

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.

The (OM654) 2.0-litre, four-cylinder, turbo-diesel, which meets Euro 6 emissions standards using AdBlue, produces 125kW of power at 3800rpm with peak torque of 400Nm served between 1700-2400rpm. The nine-speed torque converter automatic offers the choice of sequential manual-shifting using the steering wheel-mounted paddles.

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 dash display was claiming average combined consumption of 9.5L/100km when we stopped to refuel at the completion of our 281km test, of which about one third of that distance was hauling a heavy payload (see Driving).

Our own figure of 11.7 (based on actual fuel bowser and tripmeter figures) was higher but still reasonable economy for a vehicle in this GVM class in mostly urban use.

So, based on our own figures, you could expect a ‘real world’ driving range of around 800km from its 93-litre tank, which has been enlarged from 71 litres as part of the latest upgrades.

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.

Large handles on the doors and overhead shelves assist climbing aboard and there’s enough adjustment in the well-bolstered seat and leather-rimmed steering wheel to find a comfortable position.

Driver views from all angles are excellent thanks to well-designed mirrors along with cameras supported by active aids like blind-spot monitoring etc.

The cabin, with its high roof relative to seat height, has a spacious and airy feel and all controls are reasonably intuitive and easy to reach.

Unladen ride quality is surprisingly supple for a vehicle with a 6.0-tonne-plus GCM rating, combined with excellent steering feel that strikes a fine balance between minimal turning effort at low speeds (for loading etc) and firm handling response at higher speeds.

The drivetrain is also energetic, pulling strongly and cleanly from 1000rpm even though its maximum torque is tapped higher in the 1700-2400rpm zone. The automatic transmission has admirable refinement, with near-seamless shifting between its nine ratios.

The Sprinter is also impressively quiet at speeds up to 80km/h. Tyre and wind noise (the latter mainly around the large door mirrors) naturally increase at highway speeds, but remain far from intrusive. And with the engine requiring less than 2000rpm to maintain 110km/h, it’s well-suited to highway work.

To test its load-carrying ability, we forklifted 1.3 tonnes into the cargo bay which with driver equalled a payload of 1.4 tonnes. That's still almost half a tonne less than its limit.

Not surprisingly, it handled this load with ease, as handling and braking were largely unaffected and the ride quality became smoother thanks to such a big increase in sprung weight. Even so, the rear springs only compressed about 30mm.

It easily conquered our 13 per cent gradient, 2.0km-long set climb at 60km/h with this load onboard, as the auto downshifted to fourth gear to tap maximum torque when hauling this load to the summit.

Engine-braking on the way down, in a manually-selected second gear, wasn’t as robust but not unexpected given a 2.0-litre engine trying to restrain 1.4 tonnes of payload on a steep descent. Even so, the quartet of disc brakes efficiently kept speeds in check.

Overall, it was an impressive performance. However, we did note that the speed sign recognition function was not working for the duration of our test. And some welcome enhancements would be a driver’s left footrest and a fold-down inboard armrest for the driver’s seat, as fitted to its smaller Vito sibling.

ANCAP ratings do not apply to Heavy Commercial vehicles. Even so, in addition to the Sprinter’s existing long menu of passive and active safety features, the latest range adds significant enhancements as standard equipment including thorax-protecting airbags for driver and passenger, lane-keeping assist, traffic sign assist, rain-sensing wipers, tyre pressure monitoring and a parking package with reversing camera and front/rear sensors.

Also new is ‘Moving Off Information Assist’ which utilises a camera mounted in the grille plus six ultrasonic sensors to monitor an area 3.7 metres in front of the steered direction of the vehicle and 0.5 metres to the side.

This automatically activates at start-up and remains active up to 10km/h. So, if a road user is detected in the monitored area, the driver is alerted by audible and visual signals.

The latest range also introduces ‘Sideguard Assist’ which provides extended detection in the blind-spot on the passenger side. It activates when the vehicle is stationary and at low speeds, providing an extra set of eyes during parking, low-speed manoeuvring and traffic congestion.

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.

Warranty is five years/250,000km whichever occurs first and includes a roadside assist support package.

Scheduled servicing is every 12 months/40,000km. Pay-as-you-go capped-pricing for the first five scheduled services totals $5905, or a pricey average of $1181 per year. Service plans are also available.
