BMW 3 Series

Summary

Mercedes-Benz S-Class

Ever since the middle of the 1990s, I've been captivated by the Mercedes-Benz S Class. It used to be known as Sonderklasse - special class - and teenage me certainly thought it was. The one that caught my attention was the W140. A huge, two-tonne beast when that sort of mass was rare, it was loaded with amazingness and owned the road.

Part of its unique appeal was that that it was properly ugly. When it hove into view it was like a battleship entering Sydney Harbour. And it used almost as much fuel, with the V12 on board.

Over the years, genuine style has invaded the S-Class and today I found myself, for the first time, in an unusually pretty pair of S Classes - the S560 and S63 Coupes. And, astonishingly, it's the first time I've ever driven an S-Class. So with all that baggage I've built up over the years, they had a lot to live up to.

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.

Sound familiar? BMW’s been down this path before, back with 2012’s ‘ActiveHybrid 3’ and then its first 330e-badged successor four years after.

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.

Verdict

Mercedes-Benz S-Class7.3/10

Both of these vast vehicles are phenomenally comfortable - this is the kind of car that Mercedes does so well, and has done for decades. The S Class is rarely a disappointment but it's difficult to believe that such a big, heavy GT car can also dance the way the S63 does.

The S560 is far more weighted to being a GT - supremely comfortable with that active suspension, a growly, refined V8 and a cabin full of gadgets and comfort. The S63 is altogether more aggressive, to look at and to drive. Lopping the roof off both of them adds weight but, like any cruiser, also puts you out in the sun, the breeze and into your surroundings. Plus, in the case of the S63, you get more exhaust noise.

They're two very different cars and not just because of the engine. After all these years admiring it from afar, the S63 has delivered on my teenage expectations - fast, smooth and utterly mad.

Is the S Class still the car that springs to mind when you think ultimate luxury? Or has another brand taken its place? Tell us what you think in the comments below.


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.

Design

Mercedes-Benz S-Class7/10

The S Class Coupe is obviously related to the sedan but manages a svelte appearance. Slimmer hipped and with a more Coke-bottle shape, the Coupe - if you squint a bit - has a bit of the classic old pagoda about it. Obviously you can't do pillars that slim anymore, but the glass roof takes away some of the visual weight inside and out. 

The cabriolet's roof is nicely integrated and looks good when it's  up, which isn't always the case.

They all look long, though. It's obvious to see why the cars all run on 20-inch wheels - anything smaller would look hilarious.

The cabin is a fairly sensible re-imagining of the E-Class. The big twin-screen layout of the dash and multimedia system seems a bit more at home here. The chintzy Burmester speakers in the doors let down an otherwise classy cabin, which steers clear of otiose vulgarity in looks and materials.


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.

Practicality

Mercedes-Benz S-Class6/10

Well look, if you end up in the back of the S Coupe, it's not a riot of space. Obviously it has back seats (the SL doesn't even squeeze a jump seat into its considerable length) but they're for occasional, if luxurious, use.

The boot is a reasonably decent 400 litres, obviously the cabriolet loses a few litres with the roof folded. Front and rear passengers will both enjoy a pair of cupholders and the whopping long doors will each hold a bottle.


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.

Price and features

Mercedes-Benz S-Class7/10

One thing hasn't changed in nearly 20 years - the S isn't cheap. Available in coupe and cabriolet, the S560 starts at $314,900 for the former and $336,900 for the latter. Step up to the S63 pair and you'll pay from $370,500 for the coupe and $399,900 for the cab. If you're super keen for something spectacular, the twin-turbo V12-powered S65 is available for between $508,900 and $520,500, and features Swarovski crystals in the headlights, for some reason.

As you can imagine, there's quite a bit to cover, so for both cars I'll stick to the edited highlights. The S560s roll on 20-inch alloys, has a 590-watt 13 speaker sound system, digital TV, auto parking, active cruise control, panoramic glass roof, Nappa leather, active seats and power-closing doors.

It also comes standard with a heating pack that not only heats the seats but the steering wheel and centre console. In the cabriolet you also get the 'Airscarf' neck heater.

Both cars also feature's Mercedes' Magic Body Control with curve function. More of that wacky feature later.

The S63 AMG is a step up in power, price and spec. One notable change from the S560 is the loss of 'Magic Body Control', which is replaced with mere air suspension. The 20-inch alloys are 10-spoke forged units, the brakes higher performance composites with red calipers, while an AMG sports exhaust brings the noise.

Naturally, both are swathed in high-quality leather and feature dual-zone climate control, heated and cooled electric seats that adjust in every direction, deep carpets, keyless entry and start, fully digital dashboards and just about every gadget to which you can point your imagination.

Entertainment and sat nav are via Mercedes' 'Comand' system, which is displayed on a massive 12.3-inch slab of glass at the top of the dashboard. The 13-speaker Burmester-branded system is predictably impressive and with Apple CarPlay and Android Auto, you only have to use the basic software for the radio or various car controls.


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.

This leaves the Mercedes-Benz C300e and Volvo S60 T8 Hybrid from $82,300 and $84,990 respectively as the BMW’s only true equals, as they’re PHEVs, too.

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!

Engine & trans

Mercedes-Benz S-Class8/10

All four coupes and cabriolets ship with Daimler's formidable 4.0-litre twin-turbo V8. The S560 scores 345kW/700Nm to drive the rear wheels through Benz's own nine-speed automatic. With all of that available, the S560 will crack the ton in 4.6 seconds and make a wonderful racket on the way.

Moving on to the S63, the same engine delivers a massive 450kW/900Nm. The run from 0-100km/h is dispatched in just 3.5 seconds and if I thought the S560 made a good noise, the S63 with its standard sports exhaust makes a better one. Again, Mercedes' nine-speeder is along for the ride.


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.    

Fuel consumption

Mercedes-Benz S-Class7/10

The lower-powered 560 drinks 98RON at the rate of 8.5L/100km for the coupe and 9.9L/100km for the heavier cabriolet.

The S63 ups the ante with 9.9L/100km for the coupe and an identical 9.9L/100km for the cab.

Our launch program contained some...er...spirited driving, which would explain the mid to high-teens fuel figures.


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.

Driving

Mercedes-Benz S-Class8/10

Let's start with the S560. That smooth V8 rumble is all you'll ever hear if you just slot into drive and go for a leisurely spin. The nine-speed automatic continues to be a revelation to me - in the GLC63 it's good and here, once again, it's excellent, finding the right gear for the occasion and riding the fat torque curve. Other nine-speed autos are not very good at all.

The test route for the S560 played to the strengths of the car. It had some lovely winding roads, which brought the trick suspension into focus - the Magic Body Control with curve function is hilarious. While the active suspension works hard at all times to ensure the ride is smooth and drama free, the Curve mode (no, really) actually leans the car into corners.

Those of you who remember the video game Wipeout 2097 will be big fans of Curve mode. As you approach a corner, you turn the wheel and then the car leans into the bend. This isn't active damping reading the road, it's the outside suspension lifting the car and the inside lowering it, so the car feels like it's gliding, like a hovercar. It's wild but oddly calming. Mercedes reckons it's great for those who get car sick. As I didn't have my wife on hand to test this theory - she chucks at the first sign of a corner - I couldn't verify this claim. That will have to wait.

The S63 AMG is a completely different proposition. The air suspension is more than up to the job of helping smother the effects of the car's considerable weight, meaning that no matter what you're up to, the car feels reasonably light on its feet. It never feels small, though, commanding the respect of the driver and plenty of space from other road users.

And boy, do you need some space if you kick the S63 into Sport mode. In true AMG style, the electronic reins relax and the big luxury coupe cheerfully kicks off. The tail will wriggle under an unsympathetic right foot, that signature V8 roar, crackle and hiss filling your ears. The S63 is always the harder-feeling car, but it delivers with a more sporting drive than the S560.

Being the generous soul I am, I volunteered to return the S63 to its home for the evening rather than consign it to the back of a truck. On the back roads I took to reach the highway, it was rock solid - fast, predictable and a lot of fun. Once I found the boring straight bits, it turned into a supremely comfortable cruiser, ticking along in ninth at the legal limit (and being Melbourne, it was very much the legal limit), dispatching overtaking with barely a flex of a toe. 

The active cruise took the stress of keeping away from the State Revenue Office's clutches while being quiet and utterly pleasant.


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.

Safety

Mercedes-Benz S-Class8/10

The S-Class coupe comes loaded with eight airbags, ABS, stability and traction controls, forward and reverse AEB with pedestrian detection, reversing camera, crosswind assist (I know, right?), traffic-sign recognition and reverse cross traffic alert.

The S-Class Coupe does not have an ANCAP or EuroNCAP rating.


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.

BMW fits a pair of ISOFIX points for the outboard back seat positions, as well as top tethers for strap-fastened child seats.

Ownership

Mercedes-Benz S-Class7/10

Mercedes offers a three-year/unlimited-kilometre warranty with roadside assist for the duration.

The company also offers both service plans (where you pay up-front as part of the vehicle purchase) and capped-price servicing on the coupes. Servicing over three years is in the order $2500.


BMW 3 Series

BMW’s warranty is one of the worst in the business. Its meagre three years/unlimited kilometres matches Audi’s Scrooge-y efforts but is two-years shy of arch nemesis Mercedes-Benz.

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.
