BMW M5

Summary

Mercedes-Benz S-Class

It's only in the running for the title of world's best luxury car. No biggie here, then.

Like Rolex and Concorde, S-Class has become a byword for ultimate, and deserved or not, the Mercedes-Benz defines its segment despite the best efforts of the BMW 7 Series, Audi A8, Lexus LS and (sadly now-defunct) Jaguar XJ, as well as pointing the way forward with new technologies that eventually trickle down to more proletarian models.

Replacing the half-million selling W222 unveiled in 2013, the W223 is the latest in a long line since the first W187 Ponton debuted in 1951, and includes the famous ‘Finnies' and Stroke-8 models that followed immediately afterwards, but it is the 1972 W116 that really set the template.

Now, seven generations in, the 2021 S-Class is all-new again, with progressive safety and interior features that should help keep it Australia's bestselling full-sized upper-luxury sedan.

BMW M5

Remember back when people were saying the BMW M5 would lose a little something by shifting from its traditional rear-wheel drive set-up to all-wheel drive?

It would drain a little sparkle, maybe. Or some excitement. It would become more predictable, more placid - hell, even boring.

But hindsight is always 20/20, and we know now that switching to AWD has done nothing but allow BMW to funnel even more power into the tarmac, with the German brand upping power outputs and dropping lap times in one fell swoop. 

Consider the M5 Competition, then, BMW’s way of delivering the ultimate 'I told you so'. Because it’s not just the most fun, most potent AWD M5 ever - it’s the best M5 period.

Verdict

Mercedes-Benz S-Class8.5/10

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 M57.8/10

The term bigger is better doesn't often apply to performance cars, but it fits the M5 Competition perfectly. Big inside, but small outside when it matters, BMW's new performance flagship might be expensive, but there's no shortage of bang for those bucks.

Design

Mercedes-Benz S-Class7/10

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.


BMW M58/10

Let’s start with the new stuff, shall we? The BMW M5 Competition gets a new colour ('Frozen Dark Silver'), as well as new 20-inch (and lightweight) alloy wheel designs, and the grille, aero-designed wing mirrors and boot lip are finished in high-gloss black. The quad exhaust pipes are a black, too, as is the rear diffuser. Elsewhere outside, though, it’s the more muscular 5 Series of old.

Parked next to the much smaller M2, you quickly realise just how much bulk the M5 is carrying. It stretches 4966mm in length and 1903mm in width, and it looks every centimetre of those dimensions in the metal.

Climb inside, and you’re greeted with the familiar BMW interior design, with a huge centre screen, digital driver’s binnacle and a spaceship-level number of buttons surrounding the shift lever. The M5 Competition also arrives with full leather (seats and dash) trim, with carbon-effect dash inserts and aluminium pedal and foot rest trims.

Is it the most adventurous design treatment, inside or out, that we’ve ever seen? Well, no. But it looks polished and premium outside, and feels plenty comfortable inside.

Practicality

Mercedes-Benz S-Class10/10

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.


BMW M57/10

As far as performance cars go, the M5 Competition is a rolling Swiss Army Knife. For one, it’s bloody massive, which pays considerable dividends for passengers. 

Up-front, the seats are far enough apart to ensure you’ll be rubbing shoulders with exactly nobody. The centre console Is super wide (all the better for fitting all those buttons), allowing for a sizeable centre storage bin, joined by two cupholders and a second storage bin in front of the shifter which is also home to your USB, power and 'aux-in' connections.

In the back, there’s business-class levels of leg and headroom, and you can even fit another whole adult in the centre seat if you’re so inclined. The pull-down seat divider is home to two extra cupholders, sitting in front of a thick armrest, and the rear air vents get their own temperature controls. There’s an ISOFIX attachment point in each window seat, too. Pop the capacious boot and you’ll find 530 litres of storage space.

Price and features

Mercedes-Benz S-Class8/10

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.


BMW M57/10

Parking the M5 Competition on your driveway will require a $229,000 investment. That's not chump change, and a considerable jump over the regular M5, which arrived (in launch-edition guise) wearing a $199,529 price tag.

Outside, that money buys you new and lightweight 20-inch alloys, LED headlights with auto-dipping and active cornering, keyless entry and a four-tipped sports exhaust. Inside, expect a 'full leather' interior (seats, dash and door inserts),a nav-equipped screen which pairs with a 16-speaker stereo (but Apple CarPlay is a cost option) and dual-zone climate control.

Performance wise, M-designed variable dampers, a lightweight carbon-composite roof and a M sports exhaust all join the standard features list. Still, $30,000 is fair jump over the standard (and well equipped) M5. But if money is no object, you'll be buying plenty of fun. 

Engine & trans

Mercedes-Benz S-Class9/10

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.


BMW M59/10

Yes, our all-electric future feels inevitable. And yes, there’s much fun and performance to be had from battery-powered EVs. But you can’t help but hope that future is a Star Wars style far, far away when you get acquainted with the BMW M5 Competition’s monstrous twin-turbo V8.

It’s good for a wondrous 460kW (up 19kW on the regular M5) and 750Nm. Both of which are big numbers, which are fed to all four wheels via an eight-speed 'M Steptronic' automatic. Happily, you can, at the push of some buttons, make the M5 a rear-driver again. It’s slower, but damn if it ain’t much more fun.

As a result, the performance numbers need to be seen (or better yet; felt) to be believed. The near-two-tonne M5 Competition will blaze from 0-100km/h in 3.3secs, 0-200km/h in 10.8secs, and push on to a limited top speed of 250km/h (or 305km/h, provided you do some BMW driver training).

Fuel consumption

Mercedes-Benz S-Class7/10

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.


BMW M57/10

Well, BMW tells us you’ll return 10.7-10.8 litres per hundred kilometres on the combined cycle. But we would suggest that’s unlikely, unless you have Miss Daisy lounging in the back seat. Drive it like you definitely will drive it, and you can expect to pay for that privilege at the pump. 

Emissions are a claimed 243-246g/km of CO2, and the M5 Competition’s 68-litre tank will demand a premium unleaded petrol.

Driving

Mercedes-Benz S-Class10/10

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.


BMW M59/10

Things this large simply shouldn’t be this potent. Like John Goodman suddenly toppling Usain Bolt at the Olympics, the BMW M5 Competition is bulk-defyingly good at the fast stuff.

The secret is its ability to hide those sprawling dimensions on a race circuit or twisting road. BMW’s engineers have poured plenty of work into stiffening the chassis of the M5 Competition, from new anti-roll mounts to additional under-bonnet bracing, to make the brand’s biggest performance sedan feel more lithe and responsive when pushed. 

And while its size never vanishes completely - and you find yourself praying you don’t encounter oncoming traffic on skinnier roads - engaging the Competition’s sportiest settings unlocks a Copperfield-level vanishing act.

The engine helps too, of course, pushing the M5 along with staggering ease, even when you’re pottering at suburban speeds. But really flatten your foot and the big V8 will force you to reassess your knowledge of physics. It’s really very fast, the Competition, the power flowing uninterrupted to the tyres, the engine still very willing to deliver more oomph long after your courage has jumped ship. 

The steering, direct though it is, lacks some natural feel, but you are always left with the impression that the Competition is going to go where you point it.

More fun stuff? Well, you can switch the traction control to a half-off setting, allowing for some smoking, drifting heroics before it drags you back into line. BMW calls it M mode, and it’s designed to make a hero of even the most ham-fisted of pilots, myself included. The braver still can deactivate traction control all together which, combined with rear-wheel-drive mode, turns the M5 Competition into the biggest and possibly most expensive drift car of all time .

Away from the track, though, the Competition version of the M5 is almost as good as transforming into a comfortable everyday commuter as its less hairy siblings. The adaptive suspension can be softened, and the steering lightened, to make toppling traffic a doddle. 

The keen-eyed among you might well have noticed we’re yet to touch on any major downsides of the drive experience. And you'd be correct. 

Safety

Mercedes-Benz S-Class10/10

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 M58/10

BMW is yet to confirm full specifications for the M5 Competition, but you can expect the safety offering to largely mirror that of the regular M5. And while the performance variant has not been crash tested, the regular 5 Series was awarded the maximum five-star safety rating.

Expect dual front, side and curtain airbags, as well as a knee bag for the driver, and a parking camera. You'll also find AEB, active cruise (which allows for brief spells of autonomy), thanks to its lane-keep assist

Ownership

Mercedes-Benz S-Class7/10

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.


BMW M57/10

The ownership package is yet to be confirmed, the M5 Competition will be covered by BMW’s three-year/unlimited kilometre warranty. 

Service intervals are condition, rather than time or distance, based, so the car will tell you when servicing is required.
