Mercedes-Benz S-Class vs Mini Cooper

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.

The new petrol Cooper range very gently evolves the upmarket Cool Britannia cliché BMW invented with the R50 back in 2001 and fostered with every iteration since.

More of the same, only slightly updated and just improved enough to justify trading the old one in. If this appeals to you, then go for it. This is the best petrol version yet. Probably.

But the Cooper’s real spark literally and metaphorically lies within the EV version.

Two very different Minis indeed.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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.

You’ve got to hand it to BMW.

The new nose and triangular tail-light treatment on the 2013-vintage midsection look as if they were designed to all go together back in the day.

You could even mistake it for the previous Cooper EV, though side-by-side that’s less likely, since the latter ditches the upright windscreen for a more raked item, clamshell bonnet opening, horizontal bumper shutlines for shorter and more-angled ones, plastic wheel arch surrounds and pull-out door handles for flush units.

The wheels are further apart, the overhangs shorter and the lower-side surfacing broken up by an artful sheetmetal crease.

The overall length at 3876mm, width at 1744mm and height at 1432mm have increased by 55mm, 17mm and 18mm respectively over the old model, but the 2495mm wheelbase stays the same.

And that’s not all.

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.

The previous Mini 3DR featured a messy and quite overbearing dashboard design from 2013 that’s aged about as well as Robin Thicke’s videos from that year.

In contrast, the new model's is far simpler and less protruding, dramatically boosting the sense of space and light.

That said, all four occupants still sit low, with an upright windscreen ahead and beside high window sills. There’s an oversized, circular screen in the middle of a pared-back dash and a neat row of toggle switches below. It’s still pure Mini in theme.

As before, there’s enough space for even the tallest people up front, reflecting the British icon’s German packaging, with plenty of head and legroom, as well as ample width. It’s only when you jump from the EV to the petrol Cooper that you realise this feels noticeably narrower.

All Coopers regardless of fuel share the 240mm (9.4-inch) central OLED display. It might seem like visual overload at first glance, with so much going on, but after a brief period of familiarisation, the touchscreen becomes a cinch to decipher and navigate. The colour-coded driving modes, pleasingly slick screen swipe action and ultra-crisp graphics are especially noteworthy.

Revel, too, in the twist engine starter and toggle gear selector actions, that also save space and are super natural to operate. This is button-lite dashboard de-cluttering done right.

As with the previous model, the Mini’s driving position has you sitting upright, but it’s comfortable enough on the S’ sports seats we sampled this on, and everything is within reach. There’s sufficient storage. The ambient mood lighting is fun. And kudos for the deployment of animal-free materials. In fact, the Cooper’s fresh textures are quite remarkable.

We’re less fond of the glass roof with no sunlight block; there are blind spots due to the thick side pillars; and some of the lower-placed plastics do not seem $60K’s worth in a supermini this expensive.

Rear-seat access isn’t graceful, with a narrow aperture to squeeze past and a slow-moving electric seat to wait for, but that should surprise nobody given this car’s size. There’s enough space for two adults and not much else really. It’s pretty basic back there.

And even further back, Mini quotes just 210 litres VDA of luggage capacity, rising to 725L with the twin backrests dropped.

Don’t forget, though, that no spare wheel exists. Just an ever-fiddly tyre repair kit.

Meanwhile, at the other end of the Cooper…

For the duration of the original BMC/BLMC/Leyland/Austin/Rover era, the Mini was often the cheapest new car around. We’re talking bare bones motoring here, for the people.

Obviously, BMW bothers with no such democratic notion today.

The new Cooper comes in two models differentiated by engine size – the C with a 115kW 1.5-litre three-cylinder turbo and S with a 150kW 2.0-litre four-cylinder turbo. Both are carryover units, and automatic only, sadly. 

Which helps explain why the base C Core starts from a steep $41,990 (all prices are before on-road costs). Much the same car cost $10K less just five years ago.

The Core includes climate control air-conditioning, an OLED circular touchscreen, a head-up display, a reverse camera, parking sensors, wireless Apple CarPlay/Android Auto, DAB+ digital radio, a smartphone charger, ambient lighting, a heated steering wheel, 17-inch alloy wheels and a basic cruise control set-up.

You’ll need to step up to the $44,990 Cooper C Classic for adaptive cruise control, a surround-view monitor, interior camera, 'augmented reality' satellite navigation, front seat warmers, seven rather than four colour choices, 18-inch alloys, a glass roof and more.

'Sun Protection Glazing' for the latter, along with a Harmon/Kardon premium audio system, John Cooper Works (JCW) sports seats with electric adjustment and memory, fancier interior materials and a broader palette of options are part of the Cooper C Flavoured package from $47,990. 

Meanwhile, the more-powerful Cooper S auto bypasses Core and kicks off with the Classic from $49,990, Favoured from $52,990 and the JCW Sport from $54,990.

The latter includes a JCW body/interior styling, steering wheel and stripes, along with adaptive suspension, paddle shifters and uprated brakes.

Going for the 5DR Cooper equivalents adds $2000 to the price.

All up, then, with drive-away pricing, the Cooper before options is priced between $47,000 and $63,000.

Obvious rivals are the Audi A1, Fiat/Abarth 500, Citroen C3 and even Suzuki Swift Sport, though alternatives with a retro bent and driver focus might also be in BMW’s crosshairs, including the Toyota GR86, Subaru BRZ, Mazda MX-5, Ford Mustang and Nissan Z.

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.

Compared to the previous model, the new one brings more performance to the table.

The Cooper C uses BMW’s 1.5-litre three-cylinder turbo petrol engine, and pumps out 115kW of power at 6500rpm and 230Nm of torque from 1500rpm to 4600rpm. Previously it was 100kW and 220kW.

With a power-to-weight ratio of 91.3kW per tonne, it’s enough for a zero to 100km/h time of 7.7 seconds (previously 8.1s), on the way to a 225km/h top speed.

Mounted transversely, it drives the front wheels via a seven-speed dual-clutch transmission (DCT).

It’s still difficult to imagine Mini buyers not outraged by the manual’s disappearance. But don’t worry. There’s always the Suzuki Swift.

Stepping up to the Cooper S, you’ll find a 2.0-litre four-cylinder turbo-petrol unit delivering a useful 150kW at 6500rpm and 300Nm between 1450rpm and 4500rpm. It was 141kW/280Nm in the old version.

Boasting 117kW/tonne, this one needs just 6.6s to 100km/h and can achieve a 242km/h V-max.

Now known as the FAAR platform, it is an evolution of BMW’s UKL (Untere Klasse, German for ‘lower class’) modular architecture that debuted in the previous model.

Suspension is via MacPherson-style struts up front and a multi-link independent rear end.

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 new Coopers enjoy a drink more than before. By almost half a litre per 100km more, in fact.

Rated at Euro6 and running on 95 RON premium unleaded petrol, the Cooper C averages 6.0L/100km (F56: 5.6), while the more-powerful Cooper S ups that to 6.3L/100km (F56: 5.8).

In terms of carbon dioxide emissions averages, this translates to 137 and 145 grams per kilometre, respectively. With a 44L fuel tank, the potential range-average is up to around 730km.

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.

So far, similarities in design, packaging, dashboard presentation and suspension layout suggest that the electric Cooper and petrol Cooper would be like fraternal twins from behind the wheel.

But in reality, the petrol-powered Mini feels much the same as the previous model, whilst the EV is more akin to what we secretly wish the fantasy Tesla Model 1 would be like. From the future.

Now, we never had a chance to drive the Cooper C, but the closely-related (though larger and heavier) Countryman C sibling – complete with the same powertrain – proved to be a willing and feisty performer once on the go, after what seemed like protracted turbo and DCT lag.

Why the hell can’t Mini just offer manuals again?

The Cooper S, meanwhile, completely lived up to brand expectations, with the familiar, revvy snarl of BMW’s sophisticated 2.0-litre four-pot turbo providing punchy of throttle response and effortless cruising capability, though there’s still some initial acceleration hesitation.

Thankfully, the Mini’s steering is always alert, offering precision and agility by the bucketful, backed up a chassis that seems permanently glued to the road – even in the wet and wintry conditions we had to endure.

Yet, other than a ride quality that seemed better than any previous-gen Mini we’ve ever encountered and so genuinely surprised us, the Cooper S seemed a little… stale compared to the glorious SE EV we had just (reluctantly) surrendered.

A bit like having a favourite dish as leftovers for two nights in a row, it felt a bit passé in 2024, even when surrounded by that dazzling OLED dash and glitzy ambient lighting.

In every important metric – performance, handling, roadholding, ride quality, packaging and (particularly) refinement – the battery-powered Cooper is the more vibrant and alive option. And truer to the vision of the original’s creator, Alec Issigonis, as a result.

There are no crash-test ratings for the 2024 Cooper at the time of publishing.

The previous F56 managed four out of five stars with ANCAP. 

On the driver-assist tech front are AEB, lane departure warning, lane keep assist, blind-spot monitoring, rear cross-traffic alert with braking, rear-collision prevention, driver-attention monitor, tyre-pressure monitor, auto high beams and an exit warning.

However, at the time of publishing, no AEB operating parameter data was available.

Other safety features include adaptive cruise control with automatic speed-limit assistance from Classic-grade and up, anti-lock brakes, electronic stability and traction controls and nine airbags (front/side/head and interaction centre-front airbags).

A pair of child seat tether latches and twin ISOFIX latches are fitted within the rear seats.

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.

Like all Minis, the Cooper comes with a five-year/unlimited kilometre warranty and five years of roadside assistance.

There are no set service intervals, as the car’s onboard computer will alert the driver based on condition and wear/tear. That said, we recommend going every 12 months or 10,000km, just to be on the safe side.

Mini also promotes several prepaid service plans on its Australian website. According to BMW, “… both new and used Mini owners can upgrade to a MINI Service Inclusive plan for 5-years/80,000km (whichever comes first).”
