BMW 3 Series
Is the 330e the best of both worlds?
A plug-in hybrid electric vehicle (PHEV), it’s a part-time electric car for the city and a full-time sports sedan for everywhere else.
Both were based on the previous F30 3 Series shape. However, this year’s all-new G20 iteration improves the breed with a bigger boot, up to 50 per cent better range and brawnier performance.
The thing is, it shares showrooms with the 330i and M340i xDrive, which represent a powerful return-to-form for the 3 Series.
So, the question isn’t so much ‘Is the 330e a good enough PHEV?’ more so than ‘Is the PHEV worthy of the BMW badge?’ Let’s find out.
|Engine Type||2.0L turbo|
|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|
BMW 3 Series9/10
You know about Goldilocks and the Three Bears, right?
Well, its themes of too little or too much apply for buyers of an eco-focused luxury sports sedan. If a hybrid like the Lexus IS 300h isn’t electrified enough, and a pure EV such as the Tesla Model 3 is going too far, then a PHEV like the 330e plugs the gap just about perfectly.
Yes, prices are high (and especially so with a few choice options), boot capacity is on the low side for a 4.7-metre long sedan and that lusty four-pot turbo is sonically no match for a turbine-smooth BMW inline six as per the M340i, but the 330e does most of the expected things well and some of the ones you might not exceptionally.
Pay the price and you can have your cake and eat it too.
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 3 Series
Remember when BMW 3 Series were compact three-box sedans that looked like nothing else? Today’s version seems so close in size to a 5 Series that only an anorak can instantly tell them apart. In fact, at a glance, differentiating the current G20 from the old F30 generation isn’t so easy, either.
It’s no surprise, then, to learn that both the 3- and 5 Series share the company’s scalable, light but super-strong ‘Cluster Architecture’. Imbued with a large-car feel, the 330e is elegant in silhouette and handsomely detailed, its imposing stance highlighted by the M Sport lowered suspension (by 10mm) and bi-colour five-prong double-spoke 19-inch alloys and (optional) Laser-light LEDs.
Flying under the radar for an eco-warrior, there is nothing other than two ‘filler’ flaps to give the PHEV game away externally. It’s all business as usual.
The same cool insouciance permeates our 3 Series’ leather-laden and metallic-accented cabin, that is now properly spacious for four adults. It still retains the signature-BMW driver-centric dashboard angle, but the style certainly isn’t retro, with twin large digital displays and a myriad of personalisation and vehicle configuration choices underlining the 330e’s modernity.
Aided by plenty of eco incentives to go PHEV, in Europe, BMW expects the 330e to be the best selling version; that said, given the inherent conservatism of premium medium sedan buyers globally, there is virtually nothing about this model’s overall execution that is too futuristic, intimidating or oddball.
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 3 Series
For a swoopy sports sedan, the 330e’s interior is pleasingly practical and – after a little familiarisation – user-friendly. As the biggest-ever 3 Series, four average-sized adults can fit in easily, while a smaller fifth person can crowd in on the rear-centre cushion. For short periods, anyway.
One surprise is the lightness of the doors due to them being partly aluminium, which means while they close with a reassuring thud, they’re might feel flimsy at first.
No such misconceptions await once inside the cocoon-quiet cabin, thanks to solid and lush materials everywhere the eye lands and hands touch. Even the plastics seem expensive.
As the 3 Series is famous for, the 330e’s dash is driver-centric, with ample adjustability of the fat-rimmed wheel and unimpeded reach for most of the important switchgear. Sat low and cosily ensconced between door and bisecting centre console, the mood is definitely grand-touring sports sedan.
For this generation, BMW has honed the once-controversial 'iDrive' controller into an artful yet logical example of on-the-move multimedia interface and data retrieval, with a concerted effort to simplify what is a mountain of available information.
Of course, familiarisation is essential, but even a short tuition will open up a world of configuration and customisation of every single facet of the car – chassis, powertrain, climate control, audio, communication and media being the main platforms. Sounds intimidating but isn’t.
To help relax (or energise), there’s even a ‘Caring Car’ feature in the sub menus with appropriately chilled ambient lighting, audio and climate control.
Indeed, the Germans have made strides in improving the perceived quality and functionality in other areas of the latest 3 Series, such as the gear lever operation, thoughtful storage and effortlessly effective ventilation.
However, the digital instrumentation has ignored decades of classy analogue style for a messy computerised multi-view layout that is just too Space Invaders.
Sure, it’s multi-configurable and includes a less-cluttered basic screen, but where’s the sophistication and beauty here? Notice to carmakers: would you wear a watch this ugly?
Moving to the back seat, the optional sunroof might eat into rear headroom, and really long-legged travellers need to ensure the front-seat occupants are as far forward as comfortably possible, but otherwise it’s the same story of well-sculptured cushions and backrests, set within a business-class style environment.
Twin USB-C ports, a 12V outlet and temperature controls are a bonus, hungry door pockets can take a large drink bottle and the essential cupholders are set within the centre armrest.
The only giveaway that this 3 Series is hauling extra electrification is inside the boot. Somewhat shallower than the regular 480-litre item, a higher floor than usual cuts that by 105L to 375L.
But at least the battery doesn’t intrude to the point where you can’t use the cabin load-through with the tri-sected backrests folded down (via a handy lever if you’re standing behind the vehicle). A through-loading system is part of the standard 40/20/40 split-fold backrest.
The floor itself is stepped half way, but if you require a flat surface, it can be lifted to even out the area. And remember, there is no spare wheel – just tyres that can be driven ‘flat’ as required to drive you to the nearest garage.
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
BMW 3 Series
It’s clear that electrification will become the norm in the not-too-distant future, from hybrids combining internal combustion engines (ICE) with electric motors and batteries, to the full battery electric vehicle (EV) and eventually hydrogen EV experience.
Somewhere along that spectrum, and nestled between the 320i (from $68,900) and 330i (from $74,900), is the 330e.
Arriving from Germany in either racy M Sport or dreary Luxury grades from $81,900 (before on-road costs), it features an electric motor and battery pack for up to 60km of pure EV propulsion, before a four-cylinder turbo-petrol engine kicks in for in excess of 1800km between refills, officially. Range anxiety be damned.
Mind you, the similarly-engined 320i but minus the electrification is almost 300kg lighter. Blame all that extra electrification swag like an 83kW synchronous motor, 10.3kWh lithium ion battery and a five-metre 1.8kW charging cable.
Being a PHEV means it needs up to six hours to recharge from a regular 10-amp household plug, down to a minimum of around 3.5 hours from a larger power source.
In contrast, a non-plug-in, series-parallel hybrid like the Lexus IS 300h barely manages 2.0km of sub-40km/h-only EV range, before its ICE takes over to replenish a much-smaller battery pack, and relegate the electric motor to mere performance and/or economy boosters only. That’s why the Lexus is some $20,000 cheaper.
Though both promise slightly less EV range than the 330e, the former is comfort-biased while the latter is a bit of a Swedish hot-rod, blitzing all for sheer oomph while scoring all-wheel drive into the bargain.
Note, however, that from $75,425 (before tax and on-road costs) will buy you the mouthful Tesla Model 3 Standard Range Plus RWD (rear-wheel drive). As a pure EV, the Yank has kicked the ICE habit with a silent and furious need for speed.
Not that our 330e M Sport Package isn’t hot to trot, with its M Sport-enhanced suspension, brakes, aero body kit, 19-inch alloys shod with run-flat tyres (so no spare wheel), steering wheel, Alcantara/Sensonic vinyl upholstery and ‘Shadow Line’ gloss-grey trimmings. Menacing.
The BMW’s list of goodies is barely good enough for a sedan that’s over $90K drive-away. You’ll find adaptive dampers that switch seamlessly from firm to soft depending on how stiff/supple you want the ride to be, auto entry/start, stop/start, heated/folding/dipping mirrors, two USB and a single 12V ports, tri-zone climate control, electrically adjustable front seats with driver’s-side memory, three-year subscription-based in-car emergency and concierge services, Apple CarPlay (but still not Android Auto at the time of publishing), 12.3-inch digital instrumentation with head-up display, a 10.25-inch central screen, satellite navigation, extended Bluetooth connectivity, an unreliable ‘Hey, BMW’ voice-activation system, digital radio, 205W amplifier audio, a 32GB hard drive, wireless smartphone charger and a personalisation function in the key saving all your preferred settings.
On the safety and security front there’s also autonomous emergency braking (AEB), warnings and active assistance/intervention for steering, lane-change, lane-departure and front/rear cross-traffic (with braking) situations, full-auto parking with surround-view 3D cameras and sensors, adaptive cruise control with full stop/go, auto high-beam LED headlights with delay/off, rain-sensing wipers, low-speed EV-mode acoustic warnings for pedestrians and localised recharging info including range radius. Handy.
Still, a sunroof is optional, as are our car’s trick 'Laser-light' active/adaptive LEDs, ambient cabin lighting, motion-sensor electric bootlid, seat and steering wheel heaters, galvanised trim, and other goodies, amounting to over $10,000. All blow out pricing towards $100K. Ouch.
At least you can pre-set the climate control in your 330e via a BMW app. Cool!
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
BMW 3 Series
BMW’s modular (B48) 2.0-litre four-cylinder engine delivers 135kW of power and 300Nm of torque, and drives the rear wheels via a ZF eight-speed automatic. The latter is regarded as one of the best transmissions of its type in production today.
That transmission also houses the 83kW/105Nm synchronous motor, while the 10.3kWh battery pack is located underneath the back seat. Total outputs are 185kW/420Nm.
Each power source works together to create a smooth and quiet EV experience up to a published 60km, before the 2.0-litre takes over the main driving function, but powering down again when coasting or under very light throttle, to help eke out maximum mileage between refills.
There are three modes to choose from – 'Sport', 'Hybrid' and 'Electric' – with the latter allowing for pure EV driving as long as the batteries are juiced up enough; otherwise the default Hybrid setting kicks in, where both propulsion options are used to maximum efficiency.
Back in Electric mode, in Battery Control mode, the driver can pre-select a minimum battery charge level for use later on where conditions are better-suited to EV driving – such as in downtown.
There’s also a so-called ‘XtraBoost’ function, providing up to 30kW of extra power (topping out at 215kW) for short periods, and is accompanied by a fake/enhanced exhaust note. It’s a bit of a scorcher, actually, revving hungrily to the redline and reeling in the horizon like a proper BMW should.
Don't go searching for an evocative in-line six-cylinder soundtrack, however. Instead, there's simply a zingy metallic snarl as the tacho swings swiftly upwards. S mode loves holding on to each gear ratio, aided by a thoughtfully placed set of paddle shifters.
Overall, the 3 Series PHEV is surprisingly rapid – clearing the 100km/h marker needs just 5.9 seconds – but subjectively actually feels even faster. BMW limits the 330e's EV top speed to 140km/h, or 230km/h in dinosaur-fuel mode.
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.
BMW 3 Series
On the flipside, BMW reckons over 1800km is possible, thanks to the official combined figure of only 2.2 litres per 100km. That’s outstanding range, especially considering the fuel tank is a teeny 40 litres.
Maybe it was the addictive allure of all that XtraBoost oomph, or perhaps it’s the porky 1740kg throwing its weight around, but we could not better 6.3L/100km during our week with the Bavarian wunderkind.
BMW recommends either premium unleaded (95 RON plus) or E10 ethanol, so no standard stuff, please.
Meanwhile, in EV mode, less than 40km is the real-world range, and that can drop dramatically with amenities running like the AC. The EU electricity consumption figure is 15.4kW/h/100km, which is reasonable for the 330e’s size and weight.
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 3 Series
The good news is that the 330e is designed for built-up and urban environments, since it benefits from a quiet electric motor to whoosh you along almost silently and always serenely for up to that 60km official range. Acceleration is instant, punchy and remains strong as speeds quickly rise, making the BMW ideal for darting in and out of traffic gaps.
In the real world, with the climate-control switched on and other drains on the car, that drops to under 40km, though that can often be more than enough for most commutes. If there’s access to a normal 10a socket, the BMW will be fully charged to get you back home in fewer than six hours.
Of course, the beauty of a PHEV is that the main form of motivation is a brilliantly muscular and responsive BMW 2.0-litre four-cylinder turbo petrol engine, which really gives the 330e wings as a fast and fluent open-road grand tourer. It just laps the miles up.
Still, running on petrol, the Bavarian is as impressive around town, too, since there’s a hefty lump of low-down torque on tap for prompt throttle responses. The superb eight-speed torque-converter auto provides an almost supernatural ability to select the right ratio at the right time, and in a most harmonious manner too.
Perhaps this is a one-off blip in our test car, but a concerning powertrain jolt was discernible from somewhere in the transmission at step-off, as if the 330e is struggling to reconcile electric and petrol power seamlessly.
Every aspect of the BMW PHEV’s powertrain and chassis – engine, transmission, steering and suspension – can be altered from a cushy softness to a muscular firmness, according to the mood of the driver (or passengers).
Although never heavy, there is substance to the steering even at slower speeds, and the upshot is an engaging and involving experience. Switching to Sport intensifies everything, for an edgier, more athletic experience.
Great for keener folk seeking the 3 Series’ enthusiast’s machine reputation. That said, the turning circle is tight for easy manoeuvrability, while the auto parking feature helps getting the sedan into tighter spots, and generally works reliably.
Adaptive dampers do a great job in helping to smother out most of the bumps and ruts of suburbia’s roads, though larger speed humps can expose the limits of available suspension travel as well as ground clearance (147mm).
Out on the open road, the steering is a boon, working with the taut chassis for sharp handling and balanced roadholding. Displaying towering levels of roadholding, the 330e simply remains glued to the road, even at speed.
One small observation is that the 330e lacks a mechanical limited slip differential, so there isn’t quite the surgical handling crispness that elevates the latest 330i into the dynamic stratosphere.
That, plus the extra mass of the PHEV, do dull the steering’s sharpness and BMW’s overall agility slightly. Never stodgy, just not supernaturally athletic. That’s the price you pay for parsimony.
Finally, in the sportier settings, with the stability and traction controls’ hold loosened, the tail can be made to swing out, meaning the driver must remain alert and ready to reel it all back into place.
This isn’t as much a flaw as a playful aspect of the 330e’s very broad dynamic bandwidth. There’s something for everyone.
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 3 Series
As part of the G20 3 Series line-up, the 330e achieved a five-star ANCAP crash-test rating in October, 2019.
There basically isn’t an active or passive safety item left unticked in this grade, meaning AEB (operational from 5km/h to 210km/h), stability and traction control, anti-lock brakes with electronic brake-force distribution, cornering brake control and brake-assist, active lane-change and lane-departure warnings and intervention, front and rear cross-traffic alert with braking and blind-spot monitoring.
Eight airbags are fitted – front and side airbags for driver and front passenger and head airbags for all outboard seat occupants.
There’s also adaptive cruise control with full stop/go functionality, as well as a low-speed EV-mode acoustic warning for pedestrians and cyclists to get out of the way. That’s set to about 20km/h.
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 3 Series
The 330e’s servicing is condition-based, depending on how it’s driven and other factors, with a dash warning appearing to let the driver/owner know when it’s time. In the UK, a two-year/30,000km interval is advised, if that helps.
No capped-price servicing regime is offered, but the 'BMW Service Inclusive Basic' packages cover scheduled servicing from three years/40,000km to five years/80,000km, and start from $1350.
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.
