Mercedes-Benz C-Class VS Mercedes-Benz S-Class

I'm not going to lie – there are sedans out there that have an almost limo-like space inside but the C200 isn't one of them.

It's not small by any means and all occupants enjoy the comforts of decent legroom and headroom but it's not cavernous considering the specs (1437mm high/1820mm wide/4751mm long).

The optional panoramic sunroof does cut into the headroom for back seat passengers, which is something to consider if your family is very tall.

The storage is maybe a tad leaner-than-average for a car of this size. The glove box and middle console aren't massive but will suffice.

The cupholders up front can be removed if you need extra storage space for larger items and back seat passengers enjoy retractable cupholders in the armrest.

The way the front doors curve out creates a larger than normal storage bin and drink bottle holder – which help make up the difference. There is a dedicated phone pocket, to tuck it out of the way.

The boot space is 455 litres (VDA), which isn't as large as some others on the market but it was plenty big enough for my family's needs.

There's a handy under-floor storage pocket for smaller items, like the puncture repair kit, because you don't get a spare tyre in this.

When it comes to ease of use, my six-year-old loved not needing my help to get into his seat and he still enjoyed a decent view out of the wide back window.

The amenities in each row are good but not class-defining. Still, creature comforts have be well-thought through.

Front occupants enjoy heated seats and fantastic lumbar and under thigh support. Dual-zone climate control sorts out the temp, and the cool circular air vents that make loud audible 'clicks' when manoeuvred give the interior a jet cockpit vibe.

While I've never had an issue opening or closing a sedan boot, the powered lid was a nice feature to have this week.

The tech throughout is great and intuitive to use. The massive 11.9-inch touchscreen multimedia system is cool and is easy to use once you become acclimatised to Mercedes system.

The customisable digital instrument panel makes the driving experiences feel individualised.

The interior is a chilled out space with gentle scrolling touchpads taking the place of most 'push' buttons and dials.

Think of each surface as being a bit like a touchscreen tablet in how you operate it. I was a little worried the touchpads would be laggy but they're very responsive.

There's only one USB port in the whole car, which limits charging for other passengers but I did enjoy the easy connectivity of the wireless Apple CarPlay.

The electric heated front seats are a nice touch but I was amused by the 'kinetic' function on both. It's what you might call a 'massage' function on another car but here they don't really work. It's best to think of them as a way to do some (very) gentle stretching on a long trip.

The 360-degree camera view is super clear and crisp but the dynamic guidelines (which tilt the camera angle) are a bit too dynamic for my liking and I relied mostly on the bird's eye view to park.

As I've mentioned, the ambient lighting system creates a stellar atmosphere inside. I've often wondered why other car manufacturers haven't jumped on that bandwagon because it's a relatively cheap way of creating wow factor. And it generates massive wow factor in here.

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.
