BMW 2 Series vs Mercedes-Benz S-Class

What's the difference?

It may be expensive for a small coupe. And EVs have reframed performance standards to the detriment of most internal combustion engine sports cars like this – at least for acceleration times. But the M240i xDrive Coupe is far more than just about numbers, imbuing the soul and spirit of what makes this brand’s vehicles so enjoyable and memorable to drive.

A unique and most-welcome survivor today, the MY25 makeover takes all that, and improves the interior, to be at the heart of what BMW has traditionally done best (styling aside). We found parting with it at the end of our term very difficult.

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.

BMW has iconic form when it comes to coupe, err, form.

Consider the timeless E9 Coupe of 1968, its elegant E24 6 Series successor of 1976 and the chiselled E31 8 Series of 1990.

Even the sinewy E82 1 Series Coupe of 2007 still resonates.

But, despite boasting long-nose/short-tail proportions, today’s G42 looks awkward from some angles, like a Lego version of the preceding F22 of 2014, complete with cartoonishly aggressive detailing that don’t sit happily on the car.

Not Munich’s finest moment. Still, as one of the last surviving small coupes, we’re still very glad it exists. And, in a rare case of more being more, this M240i’s body kit disguises some of the heavy-handedness.

So, what’s new here? Barely earning the facelift tag outside, the MY25 2 Series Coupe gains extra colours, restyled alloys and revised exterior trim, with more body paint in the lower parts and rear apron, as well as high-gloss black for the M240i’s mirror caps.

Inside, the modifications are more profound, updating to BMW’s 'Operating System 8.5', offering improved functionality and all housed within a fetching, single-piece rectangular display screen that also takes in the instrumentation.

Along with a flat-bottomed steering wheel, redesigned air vent knobs, fewer buttons, revised trim and different ambient lighting, they refresh what was a dated-looking cabin.

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 could be forgiven for thinking you’ve stepped into a mid-sized rather than small coupe, with today’s G42 being larger in every area except wheelbase than an E46 3 Series Coupe of about 25 years ago.

Length, width, height and wheelbase dimensions are 4548mm, 1838mm, 1404mm and 2741mm, respectively, which make for a surprisingly easy-to-access and spacious cabin – at least for adults up front.

In fact, if nobody is sat behind, even a 200cm-plus individual can stretch out. German cars are great at accommodating the 99-percentile people. And head room’s not bad either, even with the standard sunroof.

BMW’s are about driving, so no shocks to learn that the M240i’s driving position is first class. Sat low and snug, this is a suitably sporty yet incredibly comfortable and high-quality environment, aided by nicely bolstered M Sport seats, a lovely steering wheel and a beautifully presented dashboard. Everything fits like a glove.

If the notion of reducing the number of buttons in the newly-extended electronic interface raises red flags (how many times have we moaned about this in most software-based Chinese vehicles?), rest assured: the M240i’s ergonomics are spot-on.

There are still plenty of switches alongside the iDrive controller and gearshifter for all major vehicle functions, Porsche-style, as well as big old physical buttons for the (soaring) audio, to back up the screen shortcuts for more-detailed functions. It only takes a few moments to learn how easy and intuitive the whole set-up is. BMW leads the way here.

Crisp, clear and colourful digital graphics almost make up for the fact that the gorgeous old analogue dials of old are extinct. Instead, the company serves up unremarkable angular instrument displays and electronic readouts. Very comprehensive and informative, they do the job, but are utterly bereft of character or style. It’s as if Munich’s designers have forgotten how to make things look pretty nowadays. Hang on, do we see a pattern emerging here?

More solid Teutonic sensibility – this time far-more artfully served up – can be found in the excellent ventilation system, ample console-sited storage and pleasingly deep door pockets, highlighting how easy the M240i is to live with.

Crash regulations demand central posts, so no pillarless sides unfortunately in this modern coupe, but frameless door glass is nice (and assists in entry/egress when retracted), enhancing that sporty sensation.

The flipside is poor side and rear vision for the driver, but – frankly – it is otherwise difficult to fault the M240i’s interior layout and presentation.

Even the back-seat area tries hard.

The seats whirr forward and back (slowly) to increase/decrease the narrow aperture as required (using a shoulder-height lever within easy reach), though you’ll need to be pretty flexible accessing the two-person buckets that await. Once ensconced there, there’s sufficient space, padding and support for most folk of up to about 180cm to travel in reasonable comfort, as long as the front-seat occupants aren’t in maximum chaise longue mode and journeys aren’t too long. The quite-upright backrest angle can’t be adjusted.

Just ensure the climate control is on. Things can become pretty stuffy, quickly. And be thankful for the air vents, extended glass area, middle armrest with cupholders and reading lights.

Further back, there is a large-ish, 390-litre boot with a low, wide and flat floor, that can be extended by tugging on a handle to drop the 40/20/40 split/fold backrests as required.

The usual tie-down hooks, lighting and power outlets are present, but you’ll search in vain for a space-saver wheel. Just the dreaded 'tyre mobility kit' that – once deployed – will likely ruin your tyre and cost hundreds to replace. No thanks.

A gashed tyre. No phone coverage. What a way to ruin a great drive day out on your favourite rural roads and in such an immensely enjoyable car. Australia demands a spare tyre.

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.

Right now, only two S-Class models are available – the S450 from $240,700 plus on-road costs and the 110mm extended-wheelbase S450L (LWB) for another $24,900 on top. Most buyers overwhelmingly opt for the latter.

Despite what the numbers may suggest, both are powered by a 3.0-litre in-line six-cylinder turbo petrol engine, delivering 270kW of power and 500Nm of torque to all four wheels via a nine-speed torque-converter automatic. Greater choices are coming later, including an all-electric version known as the EQS.

Almost every conceivable safety item is standard on the S-Class, including world-first rear-seat airbags located behind the front seats in the LWB model, taking the surround-airbag count to 10.

You'll also find route-based Speed Adaptation (adhering to the posted speed limits), Evasive Steering Assist (a sophisticated form of crash mitigation), adaptive cruise control with active stop/go, Active Lane Change Assist that automatically moves the car into the lane you indicate to), Mercedes' PreSafe crash-preparation tech that primes all the safety systems for impact, electronic stability program that encapsulates all the active driver-assist tech, Active Emergency Stop Assist, Autonomous Emergency Braking front and rear (including for cyclists and pedestrians), Traffic Sign Assist, Parking Package with Active Parking Assist and 360-degree camera and tyre pressure monitors.

On the equipment front there is the latest iteration of Mercedes' MBUX multimedia system with (another) world-first 3D display, complementing an OLED central display, powered closing doors, leather upholstery, air suspension, leather upholstery, velour floor mats, a multi-beam LED headlight system with adaptive high beams, heated and folding exterior mirrors, heat and noise-insulating acoustic glass for front side windows, dark privacy glass for rear windows, sunroof, roller sunblinds for rear windows, metallic paint and 20-inch AMG alloy wheels on runflat tyres.

Want cutting-edge multimedia? There's MBUX II's augmented reality for navigation and fingerprint scanner, as well as a more natural-speech Mercedes-Me Connect voice activation with global search.

Plus, predictive navigation with live traffic, parked vehicle locator, vehicle tracking, emergency call, maintenance management and tele-diagnostics, digital radio, Burmester 3D surround-sound system with 15 speakers and 710W amplifier, remote door locking/unlocking, geofencing, speed-fencing, valet parking, head-up display, Smart Phone integration with Apple CarPlay/Android Auto, wireless charging, ambient lighting, two-zone climate control, poplar wood trim, electric adjustment for front seats, steering column with memory function, climatised front seats, keyless entry/go with flush-fitting door handles offering hands-free access (including for the electric boot),

Besides the ‘forward facing' airbag for the rear-seat occupants, the S450L also scores electrically adjustable rear seats with memory and automatic rear climate control.

Key options – and the list is massive – include an $8700 Rear Entertainment Package, that brings rear-multimedia access, rear tablets with wireless headsets and rear-seat wireless smart phone charging, an AMG Line pack with a body kit, different alloys and larger front brakes ($6500), Business Class Package that includes aircraft-style reclining rear seating and tray tables ($14,500), Nappa leather ($5000), augmented-reality HUD ($2900), 21-inch wheels ($2000) and four-wheel steering ($2700). There's also a $14,500 Energising Package with contoured seating, heated-everything and massaging seats.

Please keep in mind our test cars featured many such extras. Tick all the boxes and you can add nearly $100,000 to the price of your S-Class.

So, is the S450 good value? Given some of the breakthrough safety and luxury features it offers, it is unique. Too bad the Federal Government's Luxury Car Tax makes them so much more expensive than they need to be.

As before, the M240i employs a 3.0-litre direct-injection turbo-charged in-line six-cylinder petrol engine, making a heady 285kW of power at 6500rpm and 500Nm of torque between 1900rpm and 5000rpm.

A ZF-supplied eight-speed torque-converter automatic transmission is fitted (and, sadly, no manual is available), driving all four wheels via an AWD system with an M Sport-tuned differential.

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.

Rated as a Euro 6d-compliant vehicle, the M240i’s average combined fuel consumption figure is 8.0 litres per 100km, for a carbon dioxide emissions average of 185 grams/km.

With a 52-litre tank brimmed with premium unleaded petrol (98 RON minimum is recommended), that should result in about 650km between refills on average.

Over a mix of urban and highway driving, we managed 8.9L/100km, which is better than the pre-facelift version’s 9.6L/100km. That’s impressive stuff for a performance-orientated sports coupe.

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 M240i xDrive’s specification reads like it’s straight out of BMW fan fiction.

Nestled within a shrunken 3 Series-derived 'CLAR' platform brandishing near-50:50 weight distribution, stuffed between beefed-up struts up front, is a strident in-line six, driving the rear or all four wheels via an M Sport differential and held up by a multi-link rear axle.

The promise here is an athletic driving machine on one hand and a cosseting grand tourer on the other, but whether the M240i can walk that fickle red line as effortlessly four years on… well, that’s what we’re here to find out. As we said earlier, sub-3.5s Teslas and the like have really messed with the bang-for-your-buck playbook since 2021.

Luckily, the reality only reiterates the 2 Series Coupe’s place in the sun. Rather than the anodyne (or artificial) whine of an electric motor, here instead is one of the greatest modern engines in the world, mated to arguably the best auto transmission ever in existence.

That’s a terrific start. And, once the button is pressed, the M240i’s performance bandwidth is deeply moving and immensely satisfying.

With a kerb weight of 1690kg, the M240i’s power to weight ratio is an impressive 168.6kW/tonne, helping it to scoot from standstill to 100km/h in 4.3 seconds, on the way to an electronically-limited top speed of 250km/h. Note that the M2 flagship is just 0.3s quicker to 100.

Pottering about town in its most benign ('Eco Pro') setting, the B58-hearted Bimmer slinks about gingerly, purring like a content tabby while skimming along over all sorts of urban roads like a luxury car costing a lot more should, taking everything in its stride. Given this is what driving is like for most people most of the time, the BMW nails it.

More throttle unleashes a surging snarl as the BMW’s speed steps up, with varying degrees of urgency according to the driver’s will and desire. Racing up through the gears, the German straight six feels like it has barely stirred; like things are just warming up.

In conjunction with Sport mode, here is where the M240i really starts to take off, leaping into action, engine roaring as speeds soar as if every road is a stretch of derestricted autobahn. The pace of this coupe is quite remarkable. Planted yet precise, the steering firms up as the chassis hunkers down, and you’re left in awe of how calm and composed the car constantly feels. Even in pouring rain.

As the roads start to snake and twist, the BMW glides through the chosen line with startling grip and confidence, without ever feeling nervous or twitchy in standard traction settings, regardless of surface or weather conditions. That’s the AWD doing its thing.

The M240i is all about nuance and control, whether you’re talking steering, handling, roadholding, braking or electronic intervention. It is refreshing to feel so connected to the driving experience so intimately.

As we said back in 2022, plonking for Sport Plus mode, with the stability and traction nannies neutered, is an easy street to big old oversteer spills and thrills, if so desired.

And then, you’re back in Eco Pro, crawling along in cocooned comfort and relying on the ADAS tech to waft you along, before being back in 'Individual' mode as the road ahead clears, with powertrain in 'Sport' but the suspension in 'Comfort'; just right for times when you just want to streak ahead of slower traffic without pummelling your spine. It’s all there for you. The M240i can do it all.

Inevitably, in Sport mode the ride’s firmness can be fatiguing on bad urban roads. Likewise, the tyre noise over coarse bitumen is tiring over longer drives. And it is all too easy to exceed the speed limit.

Earlier, we said we prefer this over the extroverted, track-focused M2, despite the latter’s astounding speed, thunderous soundtrack and tremendous dynamic capabilities, and that’s because of the M240i’s ability to deliver pleasure with everyday user-friendliness. Plus, the performance flagship is only 0.3s quicker to 100.

Maybe the latest base manual M2 might change our minds.

As it stands, on the move, the M240i is BMW in full flight, staying true to brand values but without frying your nerves or depleting your bank account too much. We love it and you should too.

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.

The W223 S-Class has not been crash-tested yet by ANCAP or European affiliate EuroNCAP, so does not have a star rating. However, Mercedes-Benz claims it has striven to create one of the safety vehicles on the planet. Who are we to argue?

Almost every conceivable safety item is standard on the S-Class, including world-first rear-seat airbags located behind the front seats in the LWB model, taking the surround-airbag count to 10.

You'll also find route-based Speed Adaptation (adhering to the posted speed limits), Evasive Steering Assist (a sophisticated form of crash mitigation), adaptive cruise control with active stop/go, Active Lane Change Assist that automatically moves the car into the lane you indicate to), Mercedes' PreSafe crash-preparation tech that primes all the safety systems for impact, electronic stability program that encapsulates all the active driver-assist tech, Active Emergency Stop Assist, Autonomous Emergency Braking front and rear (including for cyclists and pedestrians, at speeds from 7km/h to over 200km/h), Traffic Sign Assist, Parking Package with Active Parking Assist and 360-degree camera and tyre pressure monitors.

The Active Lane Keeping Assist works in a speed range of between 60km/h and 250km/h while Active Steer Assist helps the driver follow the lane at speeds of up to 210km/h.

BMW offers a five-year/unlimited kilometre warranty, matching all of its German rivals, as well as three years of roadside assistance.

As always, servicing frequency is condition-based, depending on how they’re driven, amongst other factors, with an indicator on the instrument panel to alert the driver/owner. That said, our advice is to always visit your BMW dealer annually or at every 10,000km, just to be certain.

Capped-price servicing is not offered.

However, the ‘BMW Service Inclusive Basic package’ is available at extra cost, covering scheduled servicing for five years/80,000km, as long as the scheme is subscribed to before the end of the first 12 months of first registration. A 2 Series should cost from $2380.

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.
