Mercedes-Benz S-Class vs Toyota HiAce

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.

When you consider its competitive pricing (particularly for fleets), resolute resale value, robust construction, rock-solid reliability, excellent load-hauling ability, five-star safety and all-round practicality, it’s not hard to understand why the HiAce is such a popular workhorse. It’s not perfect, like any van, but when performing its intended role it’s 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.

Toyota’s unwavering adherence to rear-wheel drive ensures the HiAce has an inherent traction advantage over its predominantly front-wheel-drive rivals, particularly when hauling heavy payloads on low-grip surfaces.

Rear-wheel drive also ensures the front wheels can be turned sharply enough for its 3210mm wheelbase to deliver an impressively tight 11.0-metre turning circle. And its 1990mm height also allows access to underground loading docks and multi-storey car parks.

The chassis design is simple and robust with MacPherson strut front suspension, a leaf-spring live rear axle, variable-ratio rack and pinion steering and (on automatic variants) four-wheel disc brakes.

There’s no mesh-type cargo barrier or solid bulkhead between the cargo bay and cabin (but both are also available as genuine accessories) and the black door-handles and unpainted black plastic front and rear bumpers are designed to best withstand the wear and tear often evident in these areas on hard-working vans.

The two-tone dash layout is neat and functional, with clear analogue instrumentation and dash controls (mostly physical dials and buttons) that are easy to reach and operate. And it sticks with a good old lever-type manual handbrake instead of an electric one. All are chosen for their rugged simplicity.

The only useful item missing is a fold-down inboard armrest for the driver’s seat, offered by numerous rivals to reduce neck and shoulder strain during long days behind the wheel.

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.

Our barn-door-equipped test vehicle has a hefty 2245kg kerb weight and 3300kg GVM, which results in a genuine one-tonne-plus payload rating of 1055kg. Up to 120kg of that weight can be carried on Toyota’s triple roof-rack set.

It’s also rated to tow up to 1500kg of braked trailer, which is less than some rivals but in reality should adequately cover most towing requirements of van operators.

And with its 4800kg GCM rating (or how much weight it can legally carry and tow at the same time), that means it can carry its maximum payload while towing its maximum trailer weight. So, that’s a combined total of more than 2.5 tonnes of cargo-carrying ability, which would comfortably meet or exceed most job requirements.

The generously-sized cargo bay, which offers an impressive 6.2 cubic metres of load volume, is accessed from either side through sliding doors with large 1010mm openings, or from the rear through the optional barn doors which can be opened to 180 degrees (with special lower hinges to hold them there) allowing easy access for forklifts.

The cargo bay is 2530mm long, 1760mm wide and 1340mm high and with 1268mm between the rear wheel housings it can swallow up to two standard Aussie pallets or up to three Euro pallets, held in place by a choice of six load-anchorage points.

There’s plenty of internal lighting, the walls and doors are lined to mid-height and the roof features a full-length internal lining, which is unusual for vans and we suspect contributes to suppression of tyre noise emanating from the rear wheel housings.

Cabin storage includes a large bottle holder and bin in the base of each front door, small-bottle/cupholders on either side of the dash and in the centre, plus a single glove box. The well-designed centre console offers another two bottle holders plus large internal storage, which is capped by a hinged lid that multi-tasks as a shallow storage tray and handy work desk.

Our test vehicle is equipped with Toyota’s ubiquitous 2.8-litre four-cylinder turbo-diesel shared by all models in the HiAce range. However, ours is equipped with the optional six-speed automatic and rear barn doors which raises the list price to $51,636.

Even so, that’s still within the ballpark of its closest rivals including the LDV G10+ Barn Door ($40,063), Hyundai Staria Load Barn Door ($46,740), and Ford’s new Transit Trend LWB Barn Door ($57,590).

Our example is also equipped with a solid-walled left-side sliding door (in preference to the standard offering with window), which HiAce buyers can specify at no extra cost when ordering.

The two-seater HiAce comes standard with 'French Vanilla' paint and 16-inch steel wheels with replaceable plastic covers, 215/70R16 tyres and a full-size spare, but there’s no protective load-floor liner for the cargo bay (a Toyota genuine accessory is available).

There’s also halogen headlights and DRLs (no fancy LEDs here, folks) and the neat two-tone cabin has a tilt/reach adjustable leather-accented steering wheel, power-adjustable lumbar support on the driver’s seat, one USB port and two 12-volt cabin sockets, plus a large centre console that offers numerous storage options.

The driver also gets a 4.2-inch driver’s info display and there’s an 8.0-inch touchscreen (plus steering wheel switches) to control the two-speaker infotainment system, which offers multiple connectivity including Apple CarPlay/Android Auto, Bluetooth, digital radio and 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.

Toyota’s well-proven 1GD-FTV 2.8 litre four-cylinder turbo-diesel, which also powers Toyota’s HiLux, Fortuna and Prado model lines, produces 130kW at 3400rpm and (in auto models like ours) 450Nm of torque between 1600-2400rpm. Its Euro 5 emissions compliance doesn’t require AdBlue, which minimises maintenance and running costs.

The refined and smooth-shifting six-speed torque converter automatic offers the choice of sequential manual shifting if required. Fuel efficiency is also optimised with full torque converter lock-up on fourth, fifth and sixth gears, along with overdrive on fifth and sixth being ideal for highway driving. The inherent traction advantage of rear-wheel drive is enhanced by an electronically controlled automatic limited-slip diff.

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.

Toyota claims combined average consumption of 7.9L/100km for our test vehicle, but the dash readout was showing 11.0L/100km when we stopped to refuel after 270km of testing.

This was conducted with the engine’s auto start/stop function switched off and comprised a mix of city, suburban and highway driving, of which about one third was hauling a near-maximum payload.

Our own figure, calculated from actual fuel bowser and tripmeter readings, was higher again at 11.8, which still isn’t bad for a vehicle with a kerb weight exceeding 2.2 tonnes driven mostly in busy urban traffic and hauling almost one tonne during our test. So, based on our ‘real-world’ consumption figures, you could expect a driving range of around 600km from its 70-litre tank.

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.

It’s easy for drivers of most shapes and sizes to find a comfortable driving position in the spacious cabin, given its height/reach adjustable steering wheel, large left footrest and supportive seating with power-adjustable lumbar support.

Although there’s a huge blind spot over the driver’s left shoulder created by the solid walls of the cargo bay, active driver aids including blind-spot monitoring, rear cross-traffic alert and rear-view camera minimise the potential hazards of changing lanes and reversing out of driveways into busy traffic.

Braking is reassuringly strong and the steering is responsive, with easy manoeuvrability thanks to the conspicuously tight turning circle and lightness of the variable-ratio steering at parking speeds.

The ride quality is reasonably supple when unladen or lightly loaded and, for a van without a bulkhead between the cabin and cargo bay, has comparatively low internal noise levels at speeds up to 80km/h.

The 2.8-litre turbo-diesel, with its sizeable 450Nm of torque, has strong low-rpm response and displays good flexibility in city and suburban driving.

Its performance is optimised by the smooth-shifting six-speed auto, which also delivers fuel-efficient highway travel that requires less than 2000rpm to maintain 110km/h. The sequential manual-shifting function can be handy in certain situations, like carrying/towing heavy loads in hilly terrain.

To test its GVM rating we forklifted 890kg into the cargo bay, which combined with the driver equalled a total payload of 990kg that was only 65kg shy of its 1055kg limit.

The stout rear leaf-springs only compressed about 30mm under this loading, which left more than 60mm of static bump-stop clearance that was more than enough to ensure there was no bottoming-out on our test route.

The turbo-diesel’s ample torque made light work of hauling this payload in city, suburban and highway driving. It was also particularly strong in the hills, where it easily conquered our 13 per cent gradient, 2.0km-long set climb in third gear.

Engine braking on the way down, in a manually selected second gear, wasn’t as strong but far from disgraced given the near one-tonne payload it was trying to restrain. Even so, its four-wheel disc brakes were more than capable of keeping speeds in check.

Our only criticism is the high internal noise levels at highway speeds, when tyre roar through the rear wheel housings can become intolerable over long distances, particularly on coarse bitumen surfaces with an empty cargo bay amplifying the noise.

In our experience, this is a problem shared by all vans at these speeds if they’re not equipped with a sealed cabin bulkhead. So, if your work involves a lot of highway travel, we would recommend fitting one that's available in Toyota’s genuine accessories range. Or buying some earplugs.

The HiAce has a five-star ANCAP rating awarded in 2019 which will expire in December 2025. It comes with seven airbags plus benchmark active safety features including AEB with pedestrian and daytime cyclist detection, lane departure alert with braking assist, speed sign recognition, blind-spot monitoring, rear cross-traffic alert, front and rear parking sensors, reversing camera and more.

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.

It is covered by a five-year/unlimited km warranty. Scheduled servicing is a relatively short six months/10,000km intervals, whichever occurs first. Capped-price of $290 per service covers the first six scheduled services over three years or 60,000km.
