BMW 440I vs BMW M440I

What's the difference?

Is now the right time to buy a 4 Series coupe? With the next-generation model a matter of months away, probably not.

That said, those buyers who decide to park a new ‘old’ 4 Series coupe in their driveway will be very pleased with their purchase.

At the end of the day, the current-generation model is still a cracking sports-luxury coupe, and more so when in 440i form. It’s just that good.

BMW has once again delivered a supremely enjoyable sports car with its new 2021 4 Series.

Sure, it might have love-it or hate-it styling, but those that dismiss the 4 Series based solely on looks are missing out on a wonderful driving experience.

With the base 420i offering all the style in a relatively affordable pricetag, while the all-wheel-drive grip of the M440i adds extra assurance at a more premium price, BMW's new 4 Series should cater to anyone looking for a premium sports coupe.

The first-generation 4 Series coupe has aged relatively well, despite sharing most of its design cues with the superseded sixth-generation 3 Series sedan.

Compared to current BMW models, the 4 Series coupe’s signature kidney grille is small, flanked by angry-looking adaptive headlights with hexagonal daytime running lights, all of which are of the LED variety.

The 440i’s standard M Sport body kit adds to the aggressive styling with chunky front bumper with three large air intakes, the outer two of which also contain the LED fog lights.

Around the side, a strong shoulder line stretches from the front wheel arches to beyond their rear counterparts, while BMW’s Air Curtains split the difference between it and the sporty skirts.

The rear end is the 440i’s simplest angle, although its bumper is spruced up with a dark-grey insert and dual exhaust tailpipes. Predictably, L-shaped LED tail-lights punctuate the styling at the rear.

Inside, the 4 Series coupe is holding up well, but it's still clearly a generation behind most other new BMW models.

That said, it’s a throwback we quite like, particularly iDrive6, which is still arguably BMW’s best multimedia system to date. Powering a floating 8.8-inch touchscreen in this instance, it’s just so intuitive, partly thanks to its rotary controller.

An 8.8-inch digital instrument cluster is a late-life addition for the 440i, and while it looks great with its drive mode-specific views, it lacks the breadth of functionality of Audi’s set-up.

The 4 Series coupe’s cabin is otherwise pretty basic despite its apparent emphasis on sportiness, although the selection of luxurious materials used throughout is top-notch.

The entire dashboard, chunky M Sport steering wheel and old-school handbrake lever are trimmed in high-quality leather, while lower-quality Dakota leather covers the sports seats, armrests and door inserts.

Soft-touch plastic is used for the door shoulders and bins, even in the second row, while hard plastic is limited to the centre console, and gloss-black trim is used on the centre stack’s audio and dual-zone climate control surrounds.

Let’s get this out of the way. The 2021 BMW 4 Series is not an ugly car, despite what you may think from the press photos found online.

Is it to everyone’s tastes? Of course not, but I find the gaudy, in-your-face gold-on-black that is Versace’s signature styling a little gross … so your milage will definitely vary on the 4 Series like mine does with high-end fashion.

In person, that grille is nowhere near as overwhelming as pictures may have led you to believe, and blends in very nicely with the aggressive and muscular front end of the 4 Series.

In profile, the high shoulder line and slim glasshouse add to the sportiness, as does the sloping roofline and butch rear haunches.

The rear though, is arguably the 4 Series best exterior angle, as the pinched bumper, wraparound tail-lights, large exhaust outlets and subtle rear diffuser combine well for a properly sporty and premium look.

All Australian-spec cars come with the M Sport package, meaning a full bodykit, and 19-inch wheels to make even the boggo 420i look aggressive on the road.

Does it work? Well if it wasn’t wearing a BMW badge then it might not get away with this ostentatious styling, but being a big premium player, we think the 4 Series gets away with being as brash and in-your-face as it is.

We actually love that BMW has taken a risk with the 4 Series’ aesthetics and is willing to push the envelope because, after all, it could have just looked like the 3 Series sans-two doors, and that’s just a bit too safe, isn’t it?

Inside, the 4 Series is familiar BMW territory, which means a thick-rimmed steering wheel, glossy shifter and brushed metal accents, as well as high-quality materials throughout.

The dashboard-integrated multimedia system is a particularly nice touch, as are the metal accents that separate the lower and upper halves of the cabin.

So, is there anything interesting about the design? Absolutely. It’s got the internet talking more than usual and will no doubt draw the eye of those wanting to stand out from the often-samey crowd of German sports cars.

Measuring 4640mm long, 1825mm wide and 1377mm tall, the 440i coupe is a true mid-sizer, and that means it’s surprisingly practical – for the most part.

Cargo capacity is more than solid, at 445L, but stow the 60/40 split-fold rear bench via a pair of manual latches located in the boot and more storage space is quickly liberated.

To make matters even better, the boot has two bag hooks and four tie-down points, making securing a load a cinch. That said, the high load lip means bulkier items can require a little more effort to accommodate.

Up front, the door bins are large enough for a regular bottle each, while a pair of cupholders separate the gear selector from a seriously shallow storage tray.

The central storage bin is on the shallow side, too, albeit not to the same degree as the dedicated storage tray. That said, much of its space can be taken up by the optional wireless smartphone charger ($200), which was fitted to our test car.

The glovebox tries its best to make up for the lack of genuine in-cabin storage options by being quite large, while storage nets are attached to the backs of the front seats.

Rear occupants can also make use of a large storage tray that resides where a middle seat would otherwise go. They also have access to a fold-down central armrest that incorporates two more cupholders.

Speaking of armrests, the rear side ones are incredibly narrow, leaving tired elbows in a bit of a pickle.

It’s not all bad news in the second row, though, as legroom and toe-room behind our 184cm driving position are very generous, with the former offering several inches of wriggle room.

We’d go as far as to say the rear quarters are comfortable, but that would require ignoring the fact that headroom is seriously compromised with the optional power-operated sunroof ($3000) fitted, with our head pressed firmly against the 440i coupe’s Anthracite roofliner.

Either way, child seats can be fitted in the second row, with ISOFIX anchorage points available for the outer seats. Speaking of which, it’s worth noting ingress and egress to the rear bench isn’t too bad, with the front seats folding forward via manual latches.

Connectivity-wise, two USB-A ports are found in the first row, split between the centre stack and the central storage bin, while three 12V power outlets are spread across the front and rear of the centre console, and the boot.

Measuring 4768mm long, 1842mm wide, 1383mm tall and with a 2851mm wheelbase, the 2021 BMW 4 Series certainly looks commanding on the road, and the generous proportions do well for interior space too.

Of note though, the M440i is slightly longer (4770mm), wider (1852mm) and taller (1393mm) than the 420i and 430i, but the slight variance doesn’t translate to any perceivable difference in practicality.

Up front, there is plenty of space for driver and passenger, with a wide array of seat adjustability offering nearly the perfect position for nearly everyone regardless of shape or size.

Storage options include a generous door pocket with separate bottle holder, large central storage cubby, generous glove box, and two cupholders sited between the shifter and climate controls.

We love that the wireless smartphone charger is tucked well away just ahead of the cupholders, meaning you don’t have to worry about keys or loose change scratching up your screen, and it doesn’t eat into any of the other storage options around the cabin.

Being a coupe, you wouldn’t expect heaps of room in the second row, and the BMW 4 Series certainly doesn’t defy expectations in this regard.

Adult passengers can get in the back easy enough, thanks to auto-folding front seats, but once there, head- and shoulder-room can be a bit tight, while legroom is dependent on the height of front passengers.

We’ve certainly been in worse back seats though, and the deeply recessed seats help alleviate some of the headroom issues, but its not a space for the claustrophobic.

Open the boot and the 4 Series will swallow up to 440 litres of volume and, thanks to the wide space, can easily accommodate a set of golf clubs or weekend luggage for two.

The second row is divided 40:20:40, so you can fold down the middle to transport skis (or timber from Bunnings) while still ferrying four.

Folding the rear seats down will increase your cargo volume, but the aperture between the boot and cabin is quite small, so you might want to keep that in mind before heading to Ikea.

BMW’s new 4 Series range is available in three flavours, kicking off with the 420i for $70,900 before on-road costs, which is powered by a 2.0-litre turbo-petrol engine (more on that below).

Standard equipment includes sport seats, LED headlights, a 12.3-inch digital instrument cluster, push-button start, automatic wipers, Alcantara/Sensetec (vinyl-like) interior trim, three-zone climate control and 10-speaker sound system, but it’s the inclusion of an M Sport package and 19-inch wheels that really elevate the look of the new 4 Series to a real sporty model.

The latter two were options in the previous generation, but so many customers (we’re told close to 90%) opted for the sportier looks that BMW just decided to bundle them into the asking price.

The 420i also comes fitted with a 10.25-inch touchscreen multimedia system that includes digital radio, satellite navigation, wireless smartphone charger, and wireless Apple CarPlay AND Android Auto (finally some love for Samsung owners!).

It’s remarkable then, that the new 420i is actually almost $4100 cheaper than the model it replaces, while also boasting more equipment, safety and torque.

Stepping up to the 430i increases pricing to $88,900 ($6400 pricier than before), while also adding more equipment such as adaptive dampers, keyless entry, surround-view camera, M Sport brakes, leather interior and active cruise control.

Outputs from the 2.0-litre turbo-petrol engine are also increased in the 430i (again, more below).

The current king of the 4 Series range until the M4 lands early next year is the M440i, priced at $116,900, but includes a 3.0-litre inline six-cylinder engine and all-wheel-drive grip.

On the outside, the M440i can be distinguished by the standard inclusion of BMW’s Laserlight technology, sunroof and heated front seats, as well as ‘Cerium Grey’ colouring for the kidney grille, tailpipe shrouds and side-view mirrors.

Being a German model, there is (of course) a smattering of options available – including remote engine start and a heated steering wheel – but none jump out as crucial or ‘must have’ in any way.

We appreciate that the base 4 Series looks largely the same as its more expensive siblings, while also offering all the key equipment you’d want out of a premium sports coupe in 2020.

The 440i coupe is motivated by a silky smooth 3.0-litre turbo-petrol in-line six-cylinder engine that punches out 240kW of power at 5500rpm and 450Nm of torque from 1380-5000rpm.

An equally silky smooth eight-speed torque-converter automatic transmission exclusively sends drive to the rear wheels – a characteristic that has become a rarity in this segment.

This combination helps the 440i coupe sprint from a standstill to 100km/h in a scant five seconds flat with launch control engaged, according to BMW. Its top speed is electronically limited to 250km/h.

Both the entry-level and mid-tier 4 Series variants (420i and 430i respectively) are powered by a 2.0-litre turbocharged petrol engine.

Under the bonnet of the 420i, the engine produces 135kW/300Nm, while the 430i ups the ante to 190kW/400Nm.

The flagship (at launch) M440i meanwhile, scores a 3.0-litre turbo-petrol inline six delivering 285kW/500Nm.

All three engines are paired with an eight-speed automatic transmission, with no manual option available on any grade.

The 420i and 430i send drive to the rear wheels, resulting in a zero to 100km/h sprint time of 7.5 and 5.8 seconds respectively, while the all-wheel-drive M440i needs just 4.5s.

Stacked up against its German rivals, the 4 Series offers a decent engine line-up, but doesn’t excel at any level compared to the Audi A5 and Mercedes-Benz C-Class coupe.

The 440i coupe will drink a claimed 6.8 litres per 100 kilometres on the combined cycle, while its carbon dioxide emissions are 159 grams per kilometre.

Our week of testing skewed towards city driving over highway stints, and we averaged 8.6L/100km, which is impressive given the six-cylinder performance on offer. And yes, we did put it to use...

The 440i coupe's 60L fuel tank takes 95RON petrol at minimum.

Officially, the 420i will sip 6.4 litres per 100km, while the 430i is slightly thirstier at 6.6L/100km.

Both aforementioned 4 Series variants will need 95 RON at the bowser.

The heavier and more potent M440i needs 7.8L/100km, while also using the more expensive 98 RON fuel.

We only drove through Melbourne country roads in our brief time with all three grades of the 4 Series and could not ascertain a reliable fuel economy figure.

Our driving did not cover an extended freeway journey or any inner-city driving, so check back to see if the quoted figures hold up to scrutiny once we get more time with the car.

The 440i coupe toe the line between sports car and luxury vehicle very, very well.

The straight-line performance is definitely there thanks to its in-line six-cylinder unit, which is one of our favourite engines in any vehicle – period.

From top to bottom, the 3.0-litre unit is absolutely delicious. Maximum torque kicks in just above idle and remains on tap deep into the top end, at which point a fleeting moment of peak power is just 500rpm away. Needless to say, acceleration is strong.

Remarkably, the engine’s twin-scroll turbo exhibits next to no lag, making for a unit that you truly want to wring out. That said, don’t expect aural pleasure when you do so, as the sound it generates is lacklustre. Yep, no enticing crackles or pops are heard here.

The automatic transmission ties everything together beautifully, providing timely, quick and smooth gear changes on the regular, even without its Sport mode engaged. And, of course, there are paddle-shifters on hand if you want to take matters into your own hands – literally.

Given the 440i coupe’s apparent performance bent, you’d be forgiven for thinking it rides like an unforgiving sports car. Well, the good news is it doesn’t.

Consisting of MacPherson-strut front and multi-link rear axles with adaptive dampers, its independent suspension set-up stands up really well to Australian roads.

While potholes and coarse-chip roads would usually be met with hesitation, the 440i coupe silences the doubters with its composed ride. Can you feel them? Yes, but they’re relatively muted, especially in a car with sporty aspirations, like this one. 

Cornering is a lot of fun, too, thanks to excellent body control. Tip its 1555kg kerb weight into a corner with intent and you’re quickly reminded why SUVs are nowhere near this fun to drive.

Simply put, the 440i coupe loves a twisty stretch of road, where its M Sport brakes (front: four-piston fixed callipers, rear: two-pot floating stoppers) and traditional rear-wheel-drive dynamics come out to play.

This experience is enhanced by its superb electric power steering, which is speed-sensitive, meaning it’s quick at low speed, for improved manoeuvrability, and ‘slow’ at high speed, for improved stability.

We absolutely adore this particular system, mainly because of its perfect weighting and surprising amount of feel. And in a surprise to no-one, it also turns in really well, too.

Of course, if you want to take the 440i coupe’s handling to the next level, you can engage its Sport drive mode, which stiffens up the adaptive dampers for even flatter cornering and adds more heft to the electric power steering. But we’d say both are unnecessary.

Anything wearing a BMW badge promises a fun and engaging drive, after all the brand’s tagline used to be the ‘ultimate driving machine’, which is exacerbated in a sporty two-door.

Luckily then, the 4 Series delivers the goods and is a thoroughly enjoyable drive in all three grades.

Taking the already brilliant new-generation 3 Series as a base, BMW has made the 4 Series lower, and added additional stiffening in the front and rear for a taught and agile handling machine.

The rear track is also increased, while the front wheels have more negative camber to help with mid-corner grip.

Though the 420i and 430i might not draw any headlines, they 2.0-litre turbo-petrol pair are fun to steer and precise with their inputs.

The 420i especially doesn’t have the punch to match its aggressive looks, but is perfectly capable at slower speeds and still a delight to tip in a corner.

The 430i meanwhile, delivers more thrills thanks to its more potent engine, but it can get a bit trashy higher in the rev range.

However, the pick of the bunch for us the M440i, not only for its extra spicy engine, but also the assurance of all-wheel drive.

Now it might be sacrilege to some to not have a rear-drive BMW, but the rear-biased xDrive system in the M440i is wonderfully tuned to deliver the same sort of natural driving characteristic of a two-wheel-drive model.

Undoubtedly the near-perfect weight distribution helps with this, while the wonderfully low driving position means the whole car feels like it pivots around the driver when turning the wheel.

The M Sport differential in the rear is also great at propelling out you out of the bends, while the adaptive suspension also has great variability between comfort and sport settings.

If we had any criticism with the driving experience? We’d have liked a bit more aural theatre, but BMW have to save the louder pops and crackles for the full-fat M4, right?

A big caveat here though is that we have yet to experience the new 4 Series in a suburban setting, with our launch route taking us directly to some twisty country roads.

We also never got to drive the 4 Series in a freeway setting, meaning all of the driving was done in twisty country roads where you would expect a BMW to excel.

BMW’s 2021 4 Series has not been crash tested by either Euro NCAP or ANCAP, and does not wear an official safety rating.

However, the mechanically related 3 Series sedan was awarded a maximum five-star rating when it was examined in October 2019, but do keep in mind that the child occupant protection scores could vary wildly due to the 4 Series’ coupe shape.

The 3 Series scored 97 per cent for the adult occupant protection test, and 87 per cent for the child occupant exam. Meanwhile, the vulnerable road user protection and safety assist tests yielded an 87 and 77 per cent result respectively.

As standard, the 4 Series is equipped with autonomous emergency braking (AEB), forward collision warning, lane departure warning, rear cross-traffic alert, reversing camera, and front and rear parking sensors.

As with all BMW models, the 4 Series comes with a three-year/unlimited-kilometre warranty with three years of roadside assistance, both of which are two years short of the premium standard now set by Mercedes-Benz.

The 440i coupe’s service intervals are every 12 months or 15,000km, whichever comes first. Owners can opt for a $1650 five-year/80,000km capped-price servicing plan, which is well-priced.

Like all new BMW models, the 4 Series comes with a three-year/unlimited kilometre warranty.

However, the benchmark for premium brands belongs to Mercedes-Benz, who offer a five-year/unlimited kilometre warranty, while Genesis matches the time period but limits travel to 100,000km.

Scheduled servicing for the 4 Series occurs every 12 months or 16,000km.

At the time of purchase, BMW offers a five-year/80,000 ‘basic’ service package that covers scheduled changing engine oil, filter, spark plugs and brake fluids.

This package costs $1650, which works out to be a very reasonable $330 per service.

A more thorough ‘plus’ plan is also available for $4500 that also covers brake pads/discs, clutch and windscreen wiper replacements over the same five-year/80,000km period.
