BMW M3

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 M3

You could argue the BMW M1, a stunning wedge of late ‘70s Giorgetto Giugiaro design, first inserted the Bavarian maker’s 'M' performance brand into the public consciousness. 

But there’s a second, more enduring alpha-numeric BMW nameplate, that’s more likely to pass the person-in-the-street word-association test.

‘M3’ is synonymous with BMW performance, from touring car competition around the globe, to more than three decades’ worth of superbly engineered and entertainingly dynamic road cars.

The subject of this review is the current (G80) M3, launched globally last year. But more than that, it’s the even spicier M3 Competition, which adds six per cent more power, and 18 percent more torque, as well as $10K to the price tag.

Does the Competition’s extra bang justify those additional bucks? Time to find out.

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 M37.9/10

Is the M3 Competition worth $10K more than the ‘base’ M3? In percentage terms it’s a relatively small jump, and if you’re already in the $150K ballpark, why not take it?  Extra performance in a technically sophisticated package more than capable of handling it. Add top-shelf safety, a laundry list of standard features, with the practicality of a four-door sedan and it’s hard to resist. The way it looks? Well, that’s up to you?

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 M37/10

It feels like once in a generation, BMW feels the need to polarise automotive opinion with a controversial design direction.

Twenty years ago, then head of design for the brand, Chris Bangle, took a fearful hammering for his determined push towards more ‘adventurous’ shapes. Passionate BMW fans picketed the company’s famous ‘four-cylinder building’ HQ in Munich demanding his departure.

And who else but Bangle’s second-in-command from those days, Adrian van Hooydonk, has been leading the design department since his boss eventually left the building in 2009.

Van Hooydonk has created another firestorm of opinion in recent years by gradually increasing the size of BMW’s signature ‘kidney grille’ to what some see as comical proportions.

The latest variation on the oversize grille theme has been applied to various concept and production models, including the M3, and its M4 sibling.

As always, a purely subjective call, but the M3’s large, descending grille puts me in mind of a well known carrot-munching, cartoon rabbit’s upper incisors.

Time will tell whether such a bold treatment ages well or lives in infamy, but there’s no denying it dominates first visual impressions of the car.

Almost as much as our test example’s ‘Isle of Man Green metallic’ paint, a deep, lustrous shade that highlights the cars’s curves and angles, and regularly stopped passers by in their tracks.  

The bulging bonnet carries angular strakes back from the grille, and features a pair of faux vents, which along with darkened headlight interiors (BMW M Lights Shadow Line), accentuate the car’s tough expression.

A modern M3 wouldn’t be an M3 without pumped up guards, in this case filled by fat 19-inch forged alloy rims at the front, and 20s at the rear. 

The framing around the windows is ‘M high-gloss Shadow Line’ black, balancing the dark front splitter and side skirts. 

The tail is a multi-layered stack of horizontal lines and sections, including a thin ‘Gurney Flap’ style bootlid spoiler, and a protruding lower third housing a deep diffuser with quad, dark chrome tailpipes either side.

Sidle up closer to the car and the crowning glory is a gloss carbon-fibre roof. It’s flawless, and looks stunning.

Just as stunning is the first viewing of our test car’s full ‘Merino’ leather interior in ‘Kyalami Orange’ and black. In combination with the bold exterior colour it’s a bit rich for my blood, but the technical, athletic feel is strong.

The dash design is little changed from other 3 Series models, although the digital instrument cluster strengthens the high-performance flavour. Look up and the ‘M headliner’ is in ‘Anthracite.’  

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 M38/10

At just under 4.8m long, a fraction over 1.9m wide, and a little over 1.4m tall, the current M3 is right in the Audi A4 and Mercedes-Benz C-Class size bracket. 

There's plenty of room up front, and lots of storage, including a big box/armrest between the front seats, as well as two large cupholders and a wireless charging pad in a recessed section in front of the gear shift (which can be closed off with a roll-top style cover).

The glove box is large and there are sizable bins in the doors with separate sections for full-size bottles.

At 183cm (6’0”), sitting behind the driver’s seat set to my position, there’s lots of rear head, leg, and toe room. Which is surprising, because in other current 3 Series models, headroom’s been tighter for me.

One of three climate control zones is reserved for the rear, with adjustable vents and digital temperature control at the back of the front centre console.

Unlike other 3 Series models there’s no fold-down centre armrest (with cupholders) in the back, but there are pockets with big bottle holders in the doors.

Power and connectivity options run to a USB-A slot and 12V socket in the front console, a USB-C port in the centre console box, and two USB-C outlets in the rear.

Boot space is 480 litres (VDA), which is slightly above average for the class, with a 40/20/40 split-folding rear seat increasing cargo flexibility. 

There are small, netted bays on both sides of the load space, tie down anchors to secure loose loads, and the boot lid has an auto function.

The M3 is a no-tow zone and don’t bother looking for a spare of any description, a repair/inflator kit is your only option.

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 M38/10

With an entry-price of $154,900, before on-road costs, the M3 Competition lines up directly with Audi’s RS 5 Sportback ($150,900), while an outlier at the edge of the M3’s orbit is the Maserati Ghibli S GranSport ($175K).

But its most obvious, long-time sparring partner, the Mercedes-AMG C 63 S has temporarily stepped out of the ring. 

An all new Mercedes-Benz C-Class is set to emerge in September this year, and the hero AMG variant will adopt F1-derived hybrid tech in a 2.0-litre, four-cylinder, powertrain. 

Expect huge performance, with a price tag exceeding the outgoing model’s circa $170K ask.

And that AMG hot rod better be loaded because as well as a bunch of performance and safety tech (covered later in the review), this M3 boasts an impressively long standard equipment list.

Included are, ‘BMW Live Cockpit Professional’ with a 12.3-inch digital instrument cluster and 10.25-inch high-res multimedia display (managed via touch, voice, or the ‘iDrive’ controller), sat nav, three-zone climate control, customisable ambient lighting, ‘Laserlight’ headlights (including ‘Selective Beam’), ‘Comfort Access’ keyless entry and start, and 16-speaker harman/kardon surround sound audio (with 464-watt, seven-channel digital amp and digital radio).

Then you can add, a full leather interior (including the steering wheel and gearshift), electrically-adjustable heated ‘M Sport’ front seats (with memory for the driver), ‘Parking Assistant Plus’ (including ‘3D Surround View & Reversing Assistant’), an auto tailgate, a head-up display, adaptive cruise control, rain-sensing wipers, wireless smartphone integration (and charging) including Apple CarPlay and Android Auto connectivity, anti-dazzle (interior and exterior) mirrors, and dual-spoke forged alloy wheels (19-inch fr / 20-inch rr).

As visual icing on the cake, carbon-fibre is sprinkled over and inside the car like shiny, lightweight confetti. The entire roof is made of the stuff, with more on the front centre console, dash, steering wheel and manual shift paddles.  

That’s a solid features list (and we haven’t bored you with all the details), substantiating a strong value equation in this small, but mega-competitive market niche.  

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 M39/10

The M3 Competition is powered by BMW’s (S58B) 3.0-litre in-line, six-cylinder engine, an all-alloy, closed deck unit featuring direct-injection, ‘Valvetronic’ variable valve timing (on the intake side), ‘Double-VANOS’ variable camshaft timing (intake and exhaust side) and twin mono-scroll turbos to produce 375kW (503hp) at 6250rpm and 650Nm from 2750rpm, all the way to 5500rpm. A solid jump from the ‘standard’ M3’s already substantial 353kW/550Nm.

Not known for sitting on their hands, BMW M’s engine techs in Munich have used 3D printing to manufacture the core of the cylinder head, incorporating internal forms not possible with conventional casting. 

This tech has not only reduced the head’s weight, but allowed its coolant ducts to be re-routed for optimal temp management.

Drive goes to the rear wheels via an eight-speed ‘M Steptronic’ (torque converter) paddle-shift automatic transmission, with ‘Drivelogic’ (adjustable shift modes) and a standard ‘Active M’ variable locking differential.

An all-wheel drive ‘M xDrive’ version is scheduled for Australian launch before the end of 2021.

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 M37/10

BMW’s official fuel economy figure for the M3 Competition, on the ADR 81/02 - urban, extra-urban cycle, is 9.6L/100km, the 3.0-litre twin-turbo six emitting 221g/km of C02 in the process.

To help get to that impressive number, BMW has deployed numerous cunning devices including, an ‘Optimum Shift Indicator’ (in manual shift mode), on-demand operation of ancillary units, and ‘Brake Energy Regeneration’ which tops up a relatively small lithium-Ion battery to power an auto stop-start system, 

Despite this tricky tech, we averaged 12.0L/100km (at the bowser), over a range of driving conditions, which is still pretty good for such a powerful and focused performance sedan.

Recommended fuel is 98 RON premium unleaded although, amazingly, 91 RON standard fuel is acceptable at a pinch. 

Either way, you’ll need 59 litres of it to fill the tank, which is enough for a range of over 600km using the factory economy figure, and close to 500km based on our real-world number.

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 M39/10

Any production-based performance sedan claimed to accelerate from 0-100km/h in less than four seconds is straight-up fast. 

BMW says the M3 Competition will hit triple figures in just 3.5sec, which is properly rapid, and a full-bore, launch-control assisted start in this car is... impressive.

Aural accompaniment is suitably raucous, but beware, at its loudest it’s mostly fake news, with synthetic engine/exhaust noise able to be dialled down or turned off altogether.

That said, with maximum torque (650Nm!) available from 2750rpm all the way to 5500rpm, mid-range pulling power is prodigious, and despite the twin turbos this engine loves to rev (thanks in no small part to a forged, lightweight crankshaft). 

Power delivery is beautifully linear, and a surge from 80-120km/h takes 2.6sec in fourth, and 3.4sec in fifth. With peak power (375kW/503hp) arriving at 6250rpm, you can thunder on to a maximum velocity of 290km/h. 

That’s if the electronically-controlled limit of 250km/h isn’t enough for you, and you’ve ticked the optional ‘M Driver’s Package’ box. Enjoy the big house!

Suspension is basically strut front, five-link rear, all in aluminium, and working in concert with ‘Adaptive M’ dampers. They are brilliant, and the transition from ‘Comfort’ to ‘Sport’ and back is amazing. 

The ride quality this car delivers in Comfort mode is nuts given it’s riding on huge rims shod with licorice thin tyres. 

The sports front seats also offer an amazing blend of comfort and extra lateral support (with the touch of a button).

In fact, fine-tuning the car’s set-up across suspension, brakes, steering, engine, and transmission calibrations through the ‘M Setup’ menu is easy and adds extra involvement. Blaringly red M1 and M2 pre-set buttons on the steering wheel allow storage of preferred settings.

The electrically-assisted steering points nicely, and road feel is excellent. 

The car remains flat and stable in enthusiastic B-road corners, the active ‘M Differential’ and ‘M Traction Control’ putting all that power down from a steady state mid-corner, through to a scorchingly fast and balanced exit. 

No surprise, front to rear weight distribution for this 1.7-tonne machine is 50:50. 

Rubber is ultra-high-performance Michelin Pilot Sport 4 S (275/35x19 fr / 285/30x20 rr) which deliver confidence-inspiring grip in the dry, as well as a couple of torrentially wet days during the latter part of our week with the car. 

And washing off speed is a fuss-free experience thanks to standard ‘M Compound’ brakes’ consisting of big ventilated and cross-drilled rotors (380mm fr / 370mm rr) clamped by six-piston fixed calipers at the front and single-piston floating units at the rear.

On top of that the integrated braking system offers Comfort and Sport pedal feel settings, altering the amount of pedal pressure required to slow the car. Stopping power is immense, and even in Sport mode brake feel is progressive.

One technical niggle is the wireless CarPlay connectivity, which I found frustratingly patchy. Didn’t test the Android equivalent this time around, though.

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 M38/10

The M3 Competition hasn’t been assessed by ANCAP, but 2.0-litre 3 Series models received a maximum five-star rating in 2019.

Standard active crash-avoidance tech includes ‘Emergency Brake Assist’ (BMW-speak for AEB) with pedestrian and cyclist detection, ‘Dynamic Brake Control’ (helps apply maximum braking power in an emergency), ‘Cornering Brake Control’, a ‘Dry Braking’ function that periodically skims the rotors (with the pads) in wet conditions, ‘integrated wheel slip limitation’, lane change warning, lane departure warning, and rear cross-traffic alert. 

There’s also ‘Park Distance Control’ (with sensors front and rear), Parking Assistant Plus (including ‘3D Surround View & Reversing Assistant’), an ‘Attentiveness Assistant’ function, and tyre pressure monitoring. 

But if an impact is unavoidable there are front, side, and knee airbags for the driver and front passenger, as well as side curtain bags covering both rows of seats. 

On sensing a crash the car will make an ‘Automatic Emergency Call’, and there’s even a warning triangle and first aid kit on board.

There are three top tether points across the rear seat with ISOFIX anchors on the two outer positions for securing baby capsules/child seats.

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 M37/10

BMW offers a three year/unlimited km warranty, which is off the pace given the majority of mainstream brands have stepped up to five-year cover, with some at seven, or even 10.

And the luxury tide is turning with premium players, Genesis, Jaguar, and Mercedes-Benz now at five years/unlimited km.

On the upside, bodywork is covered for 12 years, the paint for three, and 24-hour roadside assistance is complimentary for three years.

The ‘Concierge Service’ is another three year, complimentary deal, providing  24/7/365 access to a personalised service through a dedicated ‘BMW Customer Information Centre.’

Servicing is condition based, so the car tells you when maintenance is required, and BMW offers a range of ‘Service Inclusive’ capped price servicing plans, starting from three years/40,000km.
