Mercedes-Benz S450 vs Volvo V40

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.

I’m going to miss this V40 like I do my old phone, and for many people this hatch really could really be close to perfect: excellent safety equipment, enjoyable to drive, cool prestige styling and some lo-fi buttons and dials that are far easier to use than swiping a screen. This is your last chance to own an old, new V40.

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 V40 has been around forever (well, since 2012) but somehow it still looks great – it’s the Nicole Kidman/Rob Lowe of cars.

The thing is Volvo’s new-generation vehicles now have a different look, which will be worn by the next V40, and that seriously dates the current car.

Sure, in 2016 this V40 was updated and given 'Thor’s Hammer' LED running lights like the new-gen cars, but it’s clear the V40 has the old look.

The question is: are you the type of person who would be annoyed if this time next year somebody in the latest ‘new-look’ V40 pulled up beside you at the lights. If yes, then stop reading now… we’ll just wait a moment for you to leave.

Okay, it’s just us now. We don’t need those shallow people anyway, right? They don’t know what they’re missing out on – like an interior with lots of buttons. I’m serious the centre console actually has a numerical key pad for making phone calls. There are also lots of dials for the climate control and seat warmers and for the auto parking system.

All of these buttons will be replaced by a sexy, large touchscreen in the new V40, which will make the screen in the current one look like the slot in Ned Kelly’s helmet. Wait, don’t leave. See, I’ve road tested the new X60 and I missed just flinging a dial to make the cabin’s temperature cooler, instead I had to go into the screen’s menu, find the climate functions, and then slide my finger down a little digital ladder until I found 21 degrees. It’s a frustrating design and potentially distracting in that it takes your eyes off the road longer than twisting a dial does.

I’ll stop the rant. So, yes, the interior of the new V40 will look so sleek and minimalist, decluttered of its buttons and sporting a large vertical screen, but there are functional advantages to keeping it simple.

That said the current V40’s cabin is still special and elegant. The Inscription grade brings milled aluminium trim to the centre console and that leather steering wheel. Volvo owners would be aware of that solid, well-built feeling with a high-quality fit and finish.

What are the V40’s dimensions? Compared to the Audi A3 Sportback the V40 is 59mm longer at 4369mm end-to-end, 72mm wider at 1857mm across, and 5mm shorter in height at 1420mm.

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.

Umm, next question. Okay, the V40 is not very practical. Those small rear doors don’t open wide, making entry and exit potentially difficult for older or less limber folks.

Legroom in the back is limited – although at 191cm I can just sit behind my driving position and headroom is getting tight, too – but still there’s just enough room for me.

The V40’s cargo capacity is 335 litres and that’s smaller than the A3 Sportback’s boot space (380 litres) and the BMW 1 Series’s luggage capacity (360 litres). The aperture of the boot itself is also small.

There’s even a practicality issue with the driver’s doorway – that windscreen is so slanted that the A-pillars either side of it are hard to dodge for taller people when trying to get in, but especially when climbing out.

The Volvo V40 in the mid-range Inscription grade with the T4 engine lists for $43,990. When I road tested it for the first time five years ago (in 2013) it was $45,990, and it’s a better car now than it was then, with more standard features.

The list includes a 7.0-inch touchscreen with reversing camera, sat nav, eight-speaker sound system with CD/DVD player, digital radio, and internet connectivity – but no Apple CarPlay or Android Auto. 

Also standard are front and rear parking sensors, an auto parking system, plus power adjustable driver and front passenger seats. There’s also leather upholstery, leather-trimmed steering wheel, dual-zone climate control, 17-inch 'Sarpas' alloy wheels and proximity key entry.

The safety equipment list is impressive, too – you can read all about what’s looking after you in the safety section below.

If you wanted a model comparison, then also look at the BMW 1 Series 18i M-Sport for $43,890 or the Audi A3 Sportback 2.0TFSI for $46,400 or Mercedes-Benz A200 for $44,300.

Also, don’t forget that because the current V40 is due to be replaced, dealers will be keen to move their stock to make way for the new one and that means you should be able to get yourself a bargain.

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 V40 line-up has three petrol engines to pick from and the T4 sits right in the middle between the most powerful T5 and the least grunty T3. A 2.0-litre four-cylinder turbo-petrol engine the T4 makes 140kW/300Nm and delivers it through a smooth six-speed automatic.

That engine is up there with my favourite things about the V40 Inscription. The power figure isn’t huge but 300Nm of torque provides decent shove. A 0-100km/h time of 6.9 seconds isn’t at all slow.

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.

Volvo says the V40 should use 5.6L/100km of premium unleaded fuel over a combination of open and urban roads.

If you’re only going to stick to urban areas you’ll see higher usage – our trip computer was reporting an average of 14.9L/100km on a regular peak hour commute, but motorways drop the figure to about 8.0L/100km.

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.

That grunty 2.0-litre engine teamed with that smooth six-speed transmission goes a long way to making the V40 Inscription T4 an enjoyable car to drive.

Good handling and a fairly comfortable ride complete a prestige and easy-to-drive package that’s only really let down by heavy steering and slightly noisy suspension. That heavily sloped windscreen does present some visibility issues, but it’s not a deal breaker.

First tested in 2012, the V40 the achieved one of the highest-ever scores awarded by EuroNCAP and saw ANCAP give it the maximum five-star rating in Australia. Back then the V40 came standard with advanced safety equipment only making it onto cars these days such as AEB, it also had the world’s first pedestrian airbag, which inflates to protect people from hitting the A-pillars and windscreen.

The 2017 update added blind-spot warning as standard on the Inscription grade. A $1300 option package brings Lane Departure Warning, Lane Keeping Aid, Active High Beam Control, Forward Collision Warning and Road Sign Information. A $3000 package brings adaptive cruise control, collision warning with full auto braking, plus pedestrian and cyclist detection.

ABS, EBD, traction and stability control are of course there to step in should you need it, too. You’ll find three top tether and two ISOFIX points in the second row for child seats. A space-saver spare is under the boot floor.

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 V40 Inscription is covered by Volvo’s three-year/unlimited kilometre warranty. Volvo has two capped-price servicing programs – the $1600 Smartcare for three years and the $2950 Smartcare Plus for five years.
