BMW 4 series
BMW's new 4 Series blasted onto the world stage with a chonky schnozz on it that only a mother could love. If BMW didn't want anyone to look at the rest of the car, it did a cracking job of it, because everyone had something to say about the big gnashers now grafted to the 4's front end.
I was nervous about it, too, because the 4 Series has always been so elegant and the current 3 Series - on which it is based - is quite nice to look at. It also threatened to overshadow just how good a car the BMW 4 should be, based as it is on the excellent 3 Series.
And, of course, one also had to wonder if a sports coupe like this would be any good around town. Limited vision? Hard to get in and out of? A true four-seater, or just a squishy 2+2? So many questions.

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.

BMW 4 series7.8/10
The BMW 420i is a terrific car if you're after a bit of style and sophistication. Not everyone will warm to your car's nose, but if you get it de-chromed, like this white one, it really does look pretty good. It's a car that uses very little fuel, moves along smartly and is brimming with a decent amount of tech, even if it could do with a bit more safety gear at this price.
I reckon this car is settling well into the automotive landscape and ignoring it because of a few loudmouths think the grille is too big would be a terrible waste.
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.
BMW 4 series
The internet exploded when it became clear the big kidney grille was for real. To be fair, BMW did itself absolutely no favours by ensuring the photos of the 4 Series made the twin grille look Easter Island statue sized.
And it persisted in doing them naked, without number plates to break up the look. In the flesh, it all works, the nose is striking but not completely overblown.
BMW coupe elegance reigns supreme in profile, however, with excellent proportions, and even in base form the wheels are the right size. The slim tail-lights and sculpted tail complete the look. It's a car I think most people love looking at. Hardly anyone mentioned the grille.
The cabin is excellent, as are all of the newer BMW interiors. It's not really a base model, given the price, but the mix of Alcantara and synthetic leather is very pleasing.
The big screens for the media and instruments headline the cabin with high-tech style and while it's not avant-garde, it's sharp and feels premium, which is just as well.
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.
BMW 4 series
As a sports coupe, it's hardly a practical all-rounder but it's not a squishy 2+2 either. The rear seats are sculpted for maximum headroom and have the added bonus of holding onto rear passengers.
Six footers won't be super-comfortable but it's bearable for short trips. There are two ISOFIX points back there, too.
The front seats electrically fold out of the way for ingress and egress, but it's not an elegant process.
Front-seat passengers score two cupholders and bottle holders in the doors and a black hole for your phone and its wireless charging pad.
The boot takes an impressive 440 litres and the rear seats split and fold like good little soldiers.
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
BMW 4 series
The 420i starts at $71,900. That's a fair bit of money, I think you'll agree.
You get 19-inch wheels, a 10-speaker stereo, LED headlights with auto high beam, head-up display, power front seats, lighting package, auto-parking with reverse assistant, synthetic leather and Alcantara interior, 'Live Cockpit Professional' (fully digital dash), wireless phone charging and digital radio.
The massive 10.25-inch touchscreen may be smaller than the 12.3-inch digital dashboard, but it still looks huge. BMW's Operating System 7.0. is a cracking set-up, and you can control it via either touch or the 'iDrive' rotary dial on the console. It also has Apple CarPlay and Android Auto. Both of them, wireless. You don't read that every day.
You also get 'BMW ConnectedDrive', with some remote services that last for three years. The subscription includes things like the endearingly weird 'Caring Car' and the far less weird real-time traffic information.
The 4 Series is available in eight colours. 'Alpine White' is the only freebie while 'Black Sapphire', 'Arctic Race Blue', 'Portimao Blue', 'San Remo Green' and 'Mineral White' are $1538 each (or part of the 'Visibility Package'). 'Tanzanite Blue' and 'Dravit Grey' are a hefty $2962.
My car for the week had the $6300 Visibility Package (metallic paintwork, sunroof, BMW Laserlight, Ambient Light, which is worth it for the amazing Laserlights alone), the $2860 'Comfort Package' (lumbar support, electric boot, heated front seats, 'Comfort Access' with 'BMW Digital Key') and an $800 black pack. All this took the price to $81,860.
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!
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.
BMW 4 series
BMW's official combined-cycle figures seem to be slowly moving towards reality. The 420i's sticker figure of 6.4L/100km was met with an indicated 6.8L/100km, which was excellent going for almost exclusively suburban and urban running.
It's a solid result, but being a BMW, it's premium unleaded only for its 59-litre tank.
With my generally unsympathetic (but not psychopathic) right foot, that means a real-world range of over 800km between fills.
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.
BMW 4 series
As the platform has matured and BMW's persistence with run-flat tyres has yielded improvements in tyre construction, the 3/4 Series platform (and many others - the internal name for the platform is CLAR) has once again become the benchmark for ride and handling.
For some people reading this, that's a lot of blah blah blah but the main point is, it's a terrific thing to drive whether you're dawdling along in traffic, dealing with traffic calming or bombing down your favourite deserted road.
The Bridgestone tyres on the 420i aren't as ultimately grippy and sticky as the alternative rubber on the 430i but they work well in town and are quiet on the 80km/h roads so prevalent in Sydney.
The steering is absolutely lovely, providing just the right weight at any given speed and throwing in the road feel to inspire confidence.
Ride around town is compliant but with the whiff of fun if you decide to push things outside of the city.
Its capabilities are still more than worthwhile day-to-day, however, because the way it handles the need to duck in and out of spaces in traffic is extremely handy.
The 2.0-litre four-cylinder is as smooth as rival Audi's. It doesn't sound like much (with a few vestigial pops in Sport mode) but it's certainly got the power to get you out of sticky situations and a transmission that's willing to play ball, whether in Sport or Normal.
Without the adaptive suspension of its 430i and M 440i brethren, this is a very smooth, easygoing sports coupe, with just enough sportiness to keep you interested, if you're that way inclined.
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.
BMW 4 series
The 4 Series hasn't been tested by ANCAP or Euro NCAP and the 3's five-star rating can only be a guide because of the very different structure of the 4.
Sports cars rarely fare well in the sometimes complex rules so carmakers tend to keep them away from the clutches of crash testers.
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 4 series
Servicing is entirely reasonable at $1650 for a five-year/80,000km package that covers the 12 month/16,000km servicing regime.
At $330 per service, it includes things many carmakers don't, such as brake fluid and spark plugs.
You can go full noise with the 'Plus Package', which costs $4500 and chucks in brake pads, rotors and even windscreen-wiper replacement. That doesn't seem like terribly good value to me unless you drive like a lunatic.
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.
