Mercedes-Benz S-Class vs Peugeot Partner

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.

It might not be the most modern looking or feeling small van, but amongst its competitors, the Partner stands out for its relative value and load-lugging capabilities.

It’s somewhat fun to drive but now feels a bit plain on the inside, and could benefit from a few extra options and features to make it more comfortable and maybe even a little more customisable.

Still, I think the Peugeot Partner will fit the needs of many primarily city-based small businesses or tradies who want to work out of a compact and easy-to-drive van instead of an unwieldy and often overkill dual-cab ute.

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 Partner’s recent update brings with it a new, more contemporary face, with the ‘claw’ style light fittings clasping a body-coloured panel in place of the usual grille fitting. It also updates all the badgework to match the French brand’s passenger car range.

Thanks to these upgrades, as well as the fetching colour and Premium body-matching highlights, it looks pretty schmick at a distance, but up close you can start to tell the Partner’s relative age.

It simply doesn’t look as contemporary or coherent in its design as the much newer ground-up fifth-generation Caddy or third-generation Renault Kangoo with which it competes.

A big part of this is due to the Partner being based on a much older platform which is shared across a lot of Stellantis brands. It started life as the third-generation Citroen Berlingo in 2018, and needs to warp its look overseas to fit the Fiat Doblo, Toyota Proace and Vauxhall Combo (although the Partner is the only version sold in Australia).

As a result, up close you can see its somewhat pieced together brand identity bits and boxy, upright bodywork.

There are some odd touches, like the plastic bumper at the front not matching the gloss black highlights or body coloured bumper at the rear, and the contemporary badgework finished in a matt grey adds yet another texture and colour to the mix.

The theme continues inside, with a huge plastic dash piece jutting into the cabin space. Here, the bits from Peugeot’s passenger car range have been integrated, including the cool 'squircle' steering wheel, digital dash elements and the multimedia screen.

In the centre, the electric shifter part from cars like the current 2008 small SUV has been embedded in the sea of plastic.

It technically matches the brand identity, but it doesn't stop the Partner’s interior from feeling a bit cobbled together, rather than the more unified corporate identity which is so well executed in the VW Caddy, which is almost hard to tell apart from a Golf.

The software is another area the Partner could use some work. It’s fairly simple and straightforward to use, but the layout isn’t very customizable, both for the multimedia suite and digital dash.

Again, the Caddy runs rings around Peugeot in this department, with its more impressively-featured and nicer-looking software it shares with other VW Group passenger cars.

There are also little areas which feel like they’re behind the pace for a top-spec variant. The steering wheel is hard plastic without even the option for a softer wrap, for example, and the Caddy offers an alternate optional synthetic leather seat trim for an operator willing to dish out a little extra cash.

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.

So design-wise the Partner might barely hit the brief when it comes to matching it up with Peugeot passenger car design, but one area where it manages to shine is in-cabin storage.

There’s lots on offer, massive bottle holders and pockets in the doors, storage areas galore in the big plastic dash, with trays in the centre and passenger side, as well as behind the multimedia screen and under the shifter.

There are a set of non-variable bottle holders cut out of the top of the dash, as well as hidden storage compartments under both front passenger seats.

I should mention at this point the Partner has a three-across front bench, although actually putting three people in there will be quite the squeeze, especially given the centre of the dash juts quite far into the cabin area, leaving the centre occupant with nowhere to put their knees.

Maybe it will suit a child in a pinch if you plan to have this as a small business vehicle which may need to be dual-purpose from time to time.

There’s also a fold-down rotating table thing in the backrest of the centre position, designed to be used with a laptop. Another feature of the Partner’s dash is physical toggles and buttons for the climate controls, which are increasingly rare in favour of touch-based menus.

In terms of load area dimensions, the Partner LWB offers 3.9 cubic metres (excluding the bulkhead) and dimensions come in at 2167mm long, 1527mm wide (1229 between the arches) and 1243mm tall. This should accommodate two Euro-sized palettes.

Loading and securing should also be relatively breezy thanks to sliding doors on both sides, a barn door rear which hinges out of the way for forklift loading, and no less than 10 tie down rings.

It also scores decent LED lighting in the roof, so you can see what you’re doing in a poorly lit warehouse, or when using the load area at night.

As for capacities, the Partner LWB has a payload of 898kg. It claims a 950kg braked towing capacity (not much more than the unbraked of 740kg) although in reality 740 seems to be closer to the limit thanks to the 74kg towball download rating.

How does this compare to the Caddy? I was surprised to find the Caddy 5 in equivalent LWB form has a smaller load area (3.7 cubic metres) and a significantly lower payload of 695kg.

However, it can tow slightly more (up to a claimed 1500kg - however has a 75kg max towball download). Additionally, the Partner isn’t able to be fitted with a tailgate to replace the barn doors (an option which some buyers may prefer on the Caddy).

A full size spare wheel is present on all variants to keep you on the road.

Given the uniquely European nature of a van like this, it makes sense the remaining options offered to us are only from French and German makers.

In fact, this Peugeot Partner is one of just three left for you to choose from. Starting from $39,990, before on-roads (for a Pro SWB), the Partner goes into battle against its Gallic nemesis, the Renault Kangoo, and the defending small van champion in the form of VW’s popular fifth-generation Caddy.

Unlike its rivals, though, the Partner range is automatic only and exclusively powered by a three-cylinder, turbo-petrol engine (if you exclude the electric ePartner).

This immediately gives it a leg up, as in its most affordable form, it already undercuts the base manual Caddy (TSI220 SWB - $40,990) and most affordable automatic Kangoo (SWB auto - $41,990) although the Renault holds onto the most affordable price-tag in the segment if you’re happy shifting yourself, at $38,990 for its SWB manual.

The specific version we’re looking at for this review is the Premium LWB, which wears a price-tag of $45,990 and adds an additional 350mm to its length over the SWB.

Standard kit on Premium versions includes items otherwise missing on the Pro, like 16-inch alloy wheels instead of steel wheels, LED headlights instead of halogen, push-start ignition instead of turn-key, dual-zone climate instead of single-zone as well as body-coloured highlights, rails and door handles in place of plain plastic fittings.

Standard items across the range include a 10-inch central touchscreen with wireless Apple CarPlay and Android Auto, a digital instrument cluster, cloth seat trim, a 180-degree reversing camera, a digital rear vision mirror to make up for the standard windowless barn doors, a glaze-finish bulkhead to separate the cabin and load area, as well as an array of active safety items we’ll explore later.

The fetching blue scheme our car was painted in comes at an additional $690, and from there you can modify further with an array of factory options.

Key among them are a choice of windows for each sliding door ($486 each) or the barn door ($503), a metal cargo barrier to protect the bulkhead ($1146), an LED cargo light kit ($350), roof racks ($536) or a more comprehensive roof kit ($2610).

Additionally, long-wheelbase versions can be equipped with a cargo bay floor kit ($894), wall protection kit ($960) or the rubber floor mat which our van had ($600).

A complete towing set-up will set you back $1045 for the towbar and $510 for the wiring harness.

From a base of nearly $50K then, you can easily add a few thousand to the price once you start ticking boxes, but it is important to note not every commercial van, even ones a size up, offer this level of factory customisation.

This gives the Partner deeper (and warranty-covered) customisation for various trade purposes straight from the factory.

For what it’s worth, I matched our test car in the configurator and ended up with a final price of $52,429 with drive-away pricing set to Sydney.

Out of curiosity, I also priced up a VW Caddy Cargo LWB petrol auto with as close as I could get to the same equipment as this Partner Premium, and was surprised to find I had to tick a lot more option boxes to get LED headlights, alloy wheels (although the Caddy alloys are larger at 17-inches), premium paint, colour matching body panels, keyless entry with push-start and a rubber floor mat.

The total price for the spec-matching Caddy came in at $57,952 drive-away in Sydney.

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 is just one combustion engine option in the Partner range, a three-cylinder 1.2-litre turbocharged petrol unit producing 96kW/230Nm which drives the front wheels via an eight-speed automatic transmission.

The only alternative to this is the E-Partner which sports a 100kW/260Nm electric motor instead.

The three-cylinder petrol is a perky unit sourced from Peugeot’s passenger car line-up, although the Partner range doesn’t quite offer the VW Caddy’s breadth of options; the choice of a 1.5-litre four-cylinder petrol or a 2.0-litre diesel in two states of tune.

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.

One of the key downsides of the Peugeot’s Euro-compliant turbo-petrol engine is it requires mid-shelf 95RON fuel, which could be a blow to those who want to drill down on running costs.

Claimed fuel consumption on the official combined (urban/extra-urban) cycle is decent, at 6.3L/100km. Ours spent the week mainly urban commuting and landed closer to the official urban number of 7.3L/100km with a total of 7.2L/100km over a few hundred kilometres.

The 60-litre fuel tank should allow for roughly 950km of driving range at the official consumption. More like 830km using our test figure.

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.

One thing which I always like about these little European vans for trades is they’re usually very humane and easy to drive compared to a dual-cab or a van in a larger market segment.

They tend to offer closer to the feel of a passenger car, with some of the little luxuries which are missing in big hollow diesel units like some form of refinement and less noise.

The Partner is no different, and shone in some ways I did not expect.

The brand has done a good job of making it feel like a Peugeot passenger car from a touch-point perspective with the dash elements and the small chuckable steering wheel.

It also has a swift steering ratio, making even this LWB version feel nimble and agile for darting around corners and down tight laneways just as I’m sure its French creators envisaged.

The peppy three-cylinder engine helps the hatch-like feel. It offers a punchy turbo surge and a satisfyingly gruff soundtrack, which makes this little commercial offering quite fun to drive.

The ride is also remarkably smooth for a commercial vehicle, even completely unladen. Car-like suspension handles the bumps and potholes of the city environment well, which could make this a good choice for delivery drivers who will spend a lot of time in urban environments, and maybe are less concerned about getting so close to the GCM rating.

However, it’s not quite as polished as the Caddy, which won me over big time when the fifth generation version arrived in 2022.

The Peugeot can suffer from significant bouts of turbo lag, and its eight-speed transmission can be occasionally jerky from a stand-still, making for the odd awkward moment at T-junctions and roundabouts where this van takes a second to get going again. 

Additionally, some of the fun, refined feeling wears away over time as you constantly come into contact with the hard plastic trims of the interior, and the scratchy urethane steering wheel.

This can get a bit jarring over a full day of driving. It’s for this reason VW puts a leather-bound steering wheel in even basic versions of the Caddy these days.

The software also leaves a lot to be desired, with minimal customisation and laggy interfaces.

Sure, the reality is you’ll spend most of your time working with Apple CarPlay or Android Auto which worked perfectly in my time with the car, but it would be nice to have more customisation for the dash and a few nicer menus for the multimedia screen.

All in all, then, it’s a nice little van to drive, and is excellent at urban duties, but it has a slightly industrial character which will eventually catch up with you after a long day behind the wheel.

The Caddy is better in pretty much every way behind the wheel, but then it also costs over $5000 more in equivalent spec and can't carry as much stuff.

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 Partner is covered by a par-for-the-course five year and 200,000km warranty which applies to the rest of its light commercial range, paired with five years of roadside assistance. 

The Partner requires servicing once every 12 months or 15,000km.

When it comes to pricing, you can package the car up with either a two- or four-year service plan (priced at $400 or $1000, respectively) which Peugeot claims can save you up to $437 compared to a-la-carte servicing.
