Lexus LS VS Mercedes-Benz S-Class
- Sumptuous luxury for the price
- Impressive efficiency/performance balance
- Excellent comfort and refinement
- Styling looking a little dated
- Multimedia system too downmarket and also looking dated
- A bit more driver involvement would be terrific
- S-Class' return to splendour
- Stunning high-tech cabin presentation
- Outstanding ride and handling capabilities
- Price of entry prohibitive for most
- 3D instrumentation can make you woozy
- A tad conservative in design
Lexus is returning to its roots and playing to traditional strengths with the 2021 LS update, as the Japanese luxury brand braces itself for the imminent release of an all-new Mercedes-Benz S-Class.
On sale now from $195,953 before on-road costs, the facelift ushers in a raft of comfort, refinement, driveability and technological upgrades, striving to deliver the quietest and most luxurious experience in the upper luxury sedan segment.
The blink-and-you'll-miss-it makeover runs to redesigned headlights, wheels, bumpers and tail-light lenses, as well as the inevitable multimedia screen update, improved seating revised trim and better safety.
Along with an all-in equipment list and unparalleled levels of ownership benefits, the goal is to emulate the dramatic differences that existed between the LS and its mostly German competition more than 30 years ago, which helped make Lexus a disruptor, decades before the term was even coined.
The MY21 range will continue offering two grades – the racier F Sport and opulent Sports Luxury – in either V6 twin-turbo petrol LS 500 or V6 petrol-electric hybrid LS 500h powertrain choices, as per the XF50-generation's Australian debut back in late 2017.
The question is: has Lexus gone far enough with its limousine flagship?
|Fuel Type||Hybrid with Premium Unleaded|
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.
|Engine Type||3.0L turbo|
|Fuel Type||Premium Unleaded Petrol|
One might be surprised to learn that, without having driven the latest S-Class, rival large luxury sedans have struggled to juggle comfort and refinement with agility and speed. Even in this modern age of adaptive dampers and air suspension. The Germans, in particular, seem to struggle at times.
The latest Lexus LS, however, walks the line with impressive confidence and poise, prioritising the former yet without dropping the ball with the latter. Just keep in mind that the 500h Sports Luxury manages the balance best.
The bar may just about be raised with the bestselling Stuttgart's arrival from March, but even then, with its extensive and complete specification, outstanding hybrid efficiency/performance combination and remarkable build quality and presentation, Japan's master luxury sedan deserves to find more buyers in this country.
Well done, Lexus.
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 XF50 series is a long and imposing machine, but is also arguably the most Toyota-looking LS in history, sharing design cues with most larger sedans the company builds – and yes, even the Camry. This is a departure from the Mercedes aping ‘90s and '00 generations. If the latest S-Class can look like a 200 per cent enlarged CLA, why not?
The most obvious – and pleasing – changes are realised when the headlights are switched on, revealing the BladeScan tech. In the F Sport, the redesigned bumpers' air intakes are noticeably larger and have jazzier pattern inserts, as part of a broader exercise in differentiating the grades with what's perceived as ‘sportier' elements throughout the car. The divisive ‘Spindle' grille theme remains.
Out back – arguably the most Toyota-esque part of the LS – are piano black tail-light inserts to differentiate new from old.
If Lexus is about presenting nuanced styling evolution as to not spook the demographic, then the MY21 flagship sedan succeeds brilliantly.
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.
This is more like it.
While nowhere near the apex of striking interior design, with a dashboard that – again – is quite clearly from the contemporary Toyota way of thinking, the LS is massive inside, heaving with standard luxury and obsessively crafted in a few key touchpoint areas.
The brand makes a big noise about the floating door-sited armrests and their very obviously expensive craftspersonship, but it is eye-catching and satisfying to drink in the detailing, extending in and around into the dash seamlessly, carrying on the flowing, salubrious themes of sculptured multi-dimensional shapes. In 1989 journos were handing out similar platitudes in the original LS.
If the techno-overload of a Mercedes MBUX or Tesla's OTT tablet leave you cold, this enhances the luxury experience by adding a rich, cosy, warm ambience – though the instrumentation binnacle is familiar; all we can see is the first IS 250 of 1999, complete with its single, watch-face inspired analogue dial.
Here, of course, it's digitised and multi-configurable to accommodate sat-nav, multimedia and other vehicle-related needs, but it is a oddly nostalgic, given the brand's first BMW 3 Series rival is now almost forgotten. Still, it's interesting and isn't that what eccentric rich people who don't want to drive the cliché luxury behemoths desire?
With endless adjustability, the seats are sumptuous to the point of subsuming, in the way you'd imagine a limousine to be, but because of their bolstered support, they also can be manipulated into gently cupping you enough to stop you sliding about when throwing the Lexus about with gay abandon – more on that later on.
It doesn't need mentioning that the fit and finish is fabulous, with the enveloping luxury continuing out in the back seat. The Sport Luxury's airline-style recliners are enough to turn doubters into doe-eyed believers, with their restful, relaxing, relieving, refreshing and revitalising ways – well, to an extent that an airport massage-chair minus the coin box and dodgy stains can, in any case. But the fact remains: ensconced deep into that leather-lined luxury, slumber beckons. Namaste!
And that's the point of LS. It creates a sanctuary from the outside elements at least as effectively as Audi A8s, BMW 7s and Merc S' have costing upwards of 50 per cent more. The cabin is spacious, soothing and secure. On our extended drive of both 500 models, this was made abundantly clear with two stints behind the wheel of the visually similar ES 300h.
Quiet and refined, that car felt loud and coarse compared to the smooth silence of its supersized sibling. Mission accomplished, Lexus.
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.
PS At 550 litres (20L more than before), the boot is massive and luxurious enough to sleep in.
Price and features
Value, refinement and customer care are Lexus' traditional brand pillars.
Lexus broke through with recession-ravaged consumers at the dawn of the 1990s by firstly presenting an attractively conservative S-Class sized sedan at smaller E-Class prices, and then adding an uncannily hushed cabin of exquisite build quality, silky V8 performance, the entire kitchen sink of gadgetry and unheard-of ownership privileges, like tickets to events, free parking at selected venues and home/work vehicle pick-up at service time.
If such a strategy worked then, why not an expanded version now? After all, while sales started off slowly in Australia three decades ago, in the vital US market its impact was immense. Lexus eventually gained traction locally, but nowadays the LS lags significantly behind the leading S-Class; in 2020, it managed a three per cent share compared to Mercedes' 25.5 per cent – or just 18 registrations versus 163.
Sadly, the V8s haven't returned, but the facelift does bring a richer interior with high-quality materials to elevate comfort levels, backed up by redesigned seating and overhauled adaptive suspension dampers that also promote a cushier ride while not compromising steering/handling performance.
Meanwhile, new ambient lighting and (at last) touch-display capability for the 12.3-inch central screen and Apple CarPlay/Android Auto connectivity do at least play catch up with the rest of the industry, let alone its direct rivals.
The same applies with the fresh safety gains for the series that include a digital rear-view mirror, Lexus Connected Services (with automated collision notification, SOS call and vehicle tracking), Intersection Turning Assist (that helps keep the driver from turning into on-coming traffic or brakes the car if, whilst turning, a pedestrian crosses the road), far-broader functionality of the autonomous emergency braking systems (including greater rear-cross-traffic warning and intervention), full-speed stop/go adaptive cruise control with traffic flow capability, improved road-sign recognition, better lane-keep and assist tech and a next-gen adaptive high beam tech dubbed BladeScan with stronger lighting and anti-glare performance parameters.
These come on top of the standard adaptive dampers, height-adjustable rear air suspension, front/rear cross-traffic alert, sunroof, gesture-activated powered boot lid, soft-close doors, puddle lights, 23-speaker premium audio, digital radio, DVD player, head-up display, satellite navigation, climate control with infrared body temperature sensitivity, heated/vented front and rear outboard seating, powered seats with memory, heated steering wheel, electric rear blind and a four-camera surround-view monitor.
The F Sport from $195,953 differs from the Sport Luxury from $201,078 (both before on-road costs) with its 10 airbags, dark 20-inch alloys and exterior trim hues, brake-package boost, rear-wheel steering, variable gear ratio, unique instrumentation and dark-metallic interior themes and bolstered front seats, while the LS 500 adds active anti-roll bars front and rear.
Going Sports Luxury changes things up somewhat, with two extra airbags (rear-seat cushion items), special noise-reduced alloys, rear-zone climate control, Semi Aniline leather, a front-seat relaxation system, rear-seat tablet-style screens, powered reclinable heated/vented rear seats with ottoman and massage, rear centre armrest with touchscreen climate/multimedia control, side sunshades and – in LS 500 only – a rear cooler box.
On the owner-benefit front, ‘Encore Platinum' introduced last year builds on the regular Encore's valet servicing with benefits like free use of a Lexus for business or leisure travel within select Australian and now-New Zealand destinations (one-way only – sorry, Kiwis) for up to four times annually and lasting the first three years of ownership. There's also eight yearly free valet parking at certain shopping malls and other venues, several celebrity-laden social events/activities and discounted Caltex fuel.
With all these features as standard, the LS costs several tens of thousands of dollars less than most full-sized luxury sedan rivals with broadly similar performance outputs and optioned up with equivalent luxuries, before the Encore Premium privileges. However, while the Lexus' four-year/100,000km warranty also betters most competitors by one year, it is mileage capped while others' regimes aren't, and none beat Mercedes' five-year/unlimited program.
Though prices are up by nearly $2000, it's fair to conclude the extra kit and improvements help offset them, but it's also worth remembering that earlier last year, Lexus hiked LS prices by up to nearly $4000, and not too long before Encore Platinum was announced...
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.
Engine & trans
The LS is powered by two versions of a 3.5-litre V6 petrol engine.
Around 75 per cent of buyers choose the 500, which employs Lexus' V35A-FTS 3445cc double overhead cam 24-valve twin-turbo V6 petrol engine, delivering 310kW of power at 6000rpm and 600Nm of torque from 1600-4800rpm. Powering the rear wheels via an updated AGA0 10-speed torque-converter automatic transmission with driver-adaptive tech, it can reach 100km/h in 5.0 seconds flat, on the way to a 250km/h top speed.
For the facelift, it receives a revised twin-turbo set-up with reduced lag, new pistons and a lighter, one-piece aluminium intake manifold to save weight and cut noise paths while retaining existing outputs.
The 500h, meanwhile, gains software updates for more electrical assistance at lower revs for stronger acceleration times and feel. It employs the 8GR-FXS engine – a 3456cc naturally-aspirated variation with a higher compression ratio (13.0:1 versus the 500's 10.478:1), developing 220kW at 6600rpm and 350Nm at 5100rpm.
Being a series-parallel hybrid, there is a 132kW/300Nm permanent magnet motor and 650-system volt lithium-ion battery, making for a combined power output to 264kW. It now can run longer on pure electric – up to 129km/h compared with 70km/h before. Sending drive to the rear wheels via the L310 continuously variable transmission with a four-speed shift device and a 10-speed simulated shift control operation to mimic more natural auto responses, it requires 5.4s to hit 100km/h, and manages the same top speed as its 500 counterpart.
Both autos, by the way, have more aggressive Sport and Sport+ shift ratio software, while the M manual mode has paddle shifters.
Kerb weight varies from 2215kg (500 Sports Luxury) to 2340kg (500h Sports Luxury).
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.
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.
The LS 500 returns a combined 10.0 litres per 100km, or 14.2L/100km urban and 7.6L/100km extra urban. Thus, the combined carbon dioxide emissions rating is 227 grams per kilometre, but can range from 172-321g/km. A theoretical average range of 820km is possible.
Moving on to the hybrid, the LS 500h manages a combined 6.6L/100km, or 7.8L/100km urban and an impressive 6.2L/100km extra urban. Its combined CO2, therefore, is 150g/km, and can drop as low as 142g/km and rise as high as 180g/km.
The Hybrid's average range should be about 1240km.
Both models require premium unleaded petrol as a minimum - 95 RON in the LS 500 and 98 RON in the Hybrid.
A key goal has been on reducing the stop/start frequency of the 500h's petrol engine during high-speed driving to increase both refinement and response.
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.
No matter what it says on the badge, the LS is first and foremost a large, heavy and imposing luxury sedan. Its sporting capabilities are relative.
Keeping that in mind, the updates for the MY21 version are a success, since the largest Lexus passenger car is uncannily quiet and refined, as you might hope and expect. The ride quality is largely cushioned and free of bump intrusion inside, with a sense of gliding over most road surfaces as if they were blemish-free.
We much prefer the Sport Luxury version, and the 500h in particular, because it can run silently in electric mode for periods, and somehow feels more lavish and plusher to ride in.
Whether that's psychosomatic or actual is debatable, for essentially both the 500 and Hybrid share the same multi-link front and rear platform, adaptive dampers and rear air suspension set-up, but the impression is that this grade is the choice for those wanting to feel ultimate luxury and peace.
On paper, the 500 F Sport should be the driver's choice, since it has the racier look and set-up, as well as 600Nm of tree-trunk-pulling torque.
The thing is, it doesn't necessarily feel all that athletic, and maybe that's because the whole existence of this model is based around isolating its occupants as comfortably as possible. This is no criticism, and the LS certainly envelopes everybody as a great limo ought to, but don't expect Audi S8 levels of steering crispness or handling agility.
Anyway, if you need to feel as if you are a princess in exile escaping villains with bazookas out the back of a Kombi, then the LS does an exceptional job in keeping the 2.3-tonne-plus mass in motion, cornering safely and precisely where it is pointed to, without losing too much composure or traction in tight, fast bends. This is quite a feat, really, for the big Lexus can be hurried along a mountain pass through narrow passages like a much smaller sedan, and without being bumped out of line or off course.
Again, for all-out performance, the 500h feels stronger, especially when called on to pull ahead instantly at speed, because the electric assistance is palpable compared to the regular 500's twin-turbo V6. Both are obviously very, very fast and sufficiently responsive to throttle inputs – and it's a sign of the brand's engineering prowess that their internal serenity means the speed isn't obvious until you're looking at the speedo – but there isn't even a whiff of lag in the Hybrid. That said, once on the go, that twin-turbo V6 in the 500 soars.
Considered in this context, you have to say that the MY21 LS is an exceptionally sumptuous and sophisticated limousine with the speed, safety, security and capability of taking you from point A to B without drama or noise.
Or, for that matter, excitement.
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.
Neither the ANCAP organisation nor Euro NCAP has crash-tested an LS for this or previous generations. And, for that matter, nor has the American NHTSA or IIHS, due to low sales.
Standard safety items include 10 to 12 airbags (depending on model, with dual front, front-side and curtain items), AEB with pedestrian and cyclist detection, forward collision warning, driver attention alert, Lane Keep Assist, a Front Lateral Side Pre-Collision System, Active Steering Assist, radar-based adaptive cruise control, Parking Support Brake, Road Sign Assist (detects certain speed signs), a four-camera Panoramic View Monitor, Blind Spot Monitor, Lexus Connected Services, Electronic Stability Control, traction control, anti-lock brakes with electronic brake-force distribution and brake-assist, and parking sensors all-round. The BladeScan adaptive LED headlights with anti-dazzle tech is also fitted.
The LS' AEB functions between 5km/h and 180km/h.
Additionally, two rear-seat ISOFIX points as well as three top tethers for straps are supplied.
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?

Lexus offers a four-year 100,000km warranty, which is considered one of the worst in the industry for mileage distance, due to the low number. Most rivals offer unlimited kilometre warranties, as well as more years in some cases.
However, it does come with a three-year program covering standard logbook services completed at an authorised service centre, with the first three annual/15,000km services for the LS costing $595 apiece.
A complimentary pickup and return service from home or workplace is available, as are a loan car, exterior wash and an interior vacuum during servicing. It's all part of the Lexus Encore Owners Benefit program, offered for three years and includes 24/7 roadside assistance.
Finally, the Encore Platinum brings the aforementioned travel destination free Lexus vehicle program (four times a year over three years) in Australia and NZ, as well as numerous valet parking and events privileges, limited to a several annually, and discounted fuel at participating outlets.
