BMW 2 Series vs BMW 4 Series

What's the difference?

It may be expensive for a small coupe. And EVs have reframed performance standards to the detriment of most internal combustion engine sports cars like this – at least for acceleration times. But the M240i xDrive Coupe is far more than just about numbers, imbuing the soul and spirit of what makes this brand’s vehicles so enjoyable and memorable to drive.

A unique and most-welcome survivor today, the MY25 makeover takes all that, and improves the interior, to be at the heart of what BMW has traditionally done best (styling aside). We found parting with it at the end of our term very difficult.

The BMW M440i xDrive Gran Coupe manages to combine sleek design with a fun-to-drive personality and surprising practicality. It’s a rapid premium, four-door, five-seater offering extra flair, and in this part of the market, good value. But more than anything else it’s got a cracking in-line six under the bonnet.

BMW has iconic form when it comes to coupe, err, form.

Consider the timeless E9 Coupe of 1968, its elegant E24 6 Series successor of 1976 and the chiselled E31 8 Series of 1990.

Even the sinewy E82 1 Series Coupe of 2007 still resonates.

But, despite boasting long-nose/short-tail proportions, today’s G42 looks awkward from some angles, like a Lego version of the preceding F22 of 2014, complete with cartoonishly aggressive detailing that don’t sit happily on the car.

Not Munich’s finest moment. Still, as one of the last surviving small coupes, we’re still very glad it exists. And, in a rare case of more being more, this M240i’s body kit disguises some of the heavy-handedness.

So, what’s new here? Barely earning the facelift tag outside, the MY25 2 Series Coupe gains extra colours, restyled alloys and revised exterior trim, with more body paint in the lower parts and rear apron, as well as high-gloss black for the M240i’s mirror caps.

Inside, the modifications are more profound, updating to BMW’s 'Operating System 8.5', offering improved functionality and all housed within a fetching, single-piece rectangular display screen that also takes in the instrumentation.

Along with a flat-bottomed steering wheel, redesigned air vent knobs, fewer buttons, revised trim and different ambient lighting, they refresh what was a dated-looking cabin.

So, how does this four-door 4 Series differ from a four-door 3 Series? The answer is as plain as the nose on this car’s face.

BMW’s head of design, Adrian van Hooydonk, has been expanding the brand’s signature ‘kidney grille’ in every conceivable direction, and this is the much talked about interpretation adorning all 4 Series models (petrol, hybrid and electric) as well as the M3 sedan.

The new Gran Coupe is longer, wider, and taller than the outgoing model, and the track is broader, front and rear. The wheelbase has also been extended, now a whole 5.0mm longer than the 3 Series.

The DRLs and headlight main beams are LED with laser high beams, immense gills square up the edges of the front clip, while a vent and the strake attached to it stand the car apart. Plus, of course, the doors are frameless. 

One niggle, though. I’m not in love with the slender door handles. It’s hard to get a good grip on them, especially in the wet. 

Standard 19-inch alloy rims are shod with Pirelli P Zero rubber 245/40 fr / 255/40 rr), the roofline slopes distinctly towards the rear, a lip spoiler on the trailing edge of the tailgate is classic BMW, darkened LED tail-lights wrap around the rear corner, and a diffuser-type panel is flanked by large exhaust apertures.

Our car’s ‘Aventurine Red’ finish is a $3850 option, but to my eyes anyway it looks superb.

Exterior trim including the grille frame, front air intake inserts, mirror upper housing, model designation badges, and tailpipe are finished in ‘Cerium Grey’, which I reckon 99.9 per cent of people will see as black. 

The interior will be familiar territory for any current BMW owner, the 12.3-inch digital instrument screen sitting in a compact, hooded binnacle, and partnering with a 10.25-inch multimedia display standing proud of the dash above the broad centre stack. 

The seats are trimmed in top-shelf leather with blue contrast stitching, plus the grippy sports wheel is also wrapped in genuine hide.

BMW calls the finish on the main buttons and controls ‘Galvanic’ which translates to a slick silver metallic look and feel. Configurable ambient interior lighting is a nice touch, and the broad console enhances the driver-focused feel, with a sprinkling of carbon-fibre around the centre console and dash lifting the sense of occasion.

Overall, the interior feels clean and classy with an obvious attention to detail.  

You could be forgiven for thinking you’ve stepped into a mid-sized rather than small coupe, with today’s G42 being larger in every area except wheelbase than an E46 3 Series Coupe of about 25 years ago.

Length, width, height and wheelbase dimensions are 4548mm, 1838mm, 1404mm and 2741mm, respectively, which make for a surprisingly easy-to-access and spacious cabin – at least for adults up front.

In fact, if nobody is sat behind, even a 200cm-plus individual can stretch out. German cars are great at accommodating the 99-percentile people. And head room’s not bad either, even with the standard sunroof.

BMW’s are about driving, so no shocks to learn that the M240i’s driving position is first class. Sat low and snug, this is a suitably sporty yet incredibly comfortable and high-quality environment, aided by nicely bolstered M Sport seats, a lovely steering wheel and a beautifully presented dashboard. Everything fits like a glove.

If the notion of reducing the number of buttons in the newly-extended electronic interface raises red flags (how many times have we moaned about this in most software-based Chinese vehicles?), rest assured: the M240i’s ergonomics are spot-on.

There are still plenty of switches alongside the iDrive controller and gearshifter for all major vehicle functions, Porsche-style, as well as big old physical buttons for the (soaring) audio, to back up the screen shortcuts for more-detailed functions. It only takes a few moments to learn how easy and intuitive the whole set-up is. BMW leads the way here.

Crisp, clear and colourful digital graphics almost make up for the fact that the gorgeous old analogue dials of old are extinct. Instead, the company serves up unremarkable angular instrument displays and electronic readouts. Very comprehensive and informative, they do the job, but are utterly bereft of character or style. It’s as if Munich’s designers have forgotten how to make things look pretty nowadays. Hang on, do we see a pattern emerging here?

More solid Teutonic sensibility – this time far-more artfully served up – can be found in the excellent ventilation system, ample console-sited storage and pleasingly deep door pockets, highlighting how easy the M240i is to live with.

Crash regulations demand central posts, so no pillarless sides unfortunately in this modern coupe, but frameless door glass is nice (and assists in entry/egress when retracted), enhancing that sporty sensation.

The flipside is poor side and rear vision for the driver, but – frankly – it is otherwise difficult to fault the M240i’s interior layout and presentation.

Even the back-seat area tries hard.

The seats whirr forward and back (slowly) to increase/decrease the narrow aperture as required (using a shoulder-height lever within easy reach), though you’ll need to be pretty flexible accessing the two-person buckets that await. Once ensconced there, there’s sufficient space, padding and support for most folk of up to about 180cm to travel in reasonable comfort, as long as the front-seat occupants aren’t in maximum chaise longue mode and journeys aren’t too long. The quite-upright backrest angle can’t be adjusted.

Just ensure the climate control is on. Things can become pretty stuffy, quickly. And be thankful for the air vents, extended glass area, middle armrest with cupholders and reading lights.

Further back, there is a large-ish, 390-litre boot with a low, wide and flat floor, that can be extended by tugging on a handle to drop the 40/20/40 split/fold backrests as required.

The usual tie-down hooks, lighting and power outlets are present, but you’ll search in vain for a space-saver wheel. Just the dreaded 'tyre mobility kit' that – once deployed – will likely ruin your tyre and cost hundreds to replace. No thanks.

A gashed tyre. No phone coverage. What a way to ruin a great drive day out on your favourite rural roads and in such an immensely enjoyable car. Australia demands a spare tyre.

At close to 4.8m long the 4 Series Gran Coupe is a sizeable machine. Up front, the feeling is airy and comfortable, and the rear is surprisingly spacious, especially in light of the car's sloping roofline.

At 183cm I have to fold myself tightly to fit under the low roof, but once inside I have enough room to sit behind the driver’s seat set for my position with more than enough legroom and adequate headroom. Put three full-size adults across the back row, though, and there will be breathing difficulties.

Kids will be fine, however, and individual vents with adjustable temp in the rear was a big plus during a particularly hot test week.

For storage there are generous door bins in the front with room for large bottles, a decent glove box, dual cupholders in the centre console, a reasonable lidded bin (which doubles as a centre armrest), and the wireless device charging bay (forward of the gearshift) makes a handy oddments space when not in use.

In the rear, again the doors feature pockets with room for (medium-size) bottles, there’s a fold down centre armrest with two cupholders, but thanks to the one-piece shells on our test car’s optional M Sport front seats there are no map pockets.

Power and connectivity runs to a USB-A socket and a 12V outlet in the front centre console, as well a USB-C port in the front storage bin, a pair of USB-Cs in the rear, and a 12V outlet in the boot.

Speaking of which, lift the tailgate and with the rear seat upright we were able to fit all three of our suitcases or the beefy CarsGuide pram into the healthy 470-litre (VDA) boot space.

Lower the 40/20/40 split-folding rear seat down and 1290 litres of volume is at your disposal. Plus there are handy bag hooks and tie-down anchors to help secure loose loads.

You can also tow a braked trailer up to 1.8 tonnes (750kg unbraked), but don’t bother looking for a spare of any description, a repair/inflator kit is your only option.

We’re in a zone some way North of $100K here with cost-of-entry running to $115,900, before on-road costs. So, as well as the included powertrain, suspension, and safety tech you should rightfully be expecting a lengthy standard features list.

And the M440i Gran Coupe goes toe-to-toe with its heavyweight Euro competition, featuring three-zone climate control air, adaptive cruise control, ‘Laserlight’ headlights, that 12.3-inch ‘BMW Live cockpit Professional’ instrument display and 10.25-inch ‘Control Display’ multimedia touchscreen managing navigation, the 16-speaker/464W harmon/kardon Surround Sound audio system (with Apple CarPlay and Android Auto integration) and a host of other on-board functions.

There’s also the ‘Vernasca’ Black leather trim, an electric glass sunroof, the leather-trimmed sports steering wheel, the electric sports front seats are heated and there’s wireless charging for compatible devices.

As before, the M240i employs a 3.0-litre direct-injection turbo-charged in-line six-cylinder petrol engine, making a heady 285kW of power at 6500rpm and 500Nm of torque between 1900rpm and 5000rpm.

A ZF-supplied eight-speed torque-converter automatic transmission is fitted (and, sadly, no manual is available), driving all four wheels via an AWD system with an M Sport-tuned differential.

Under the bonnet is BMW’s (B58) all-alloy 3.0-litre twin-scroll turbo intercooled, in-line six-cylinder engine, driving all four wheels via an eight-speed automatic transmission and electronically controlled clutch pack, as well as an electronic limited-slip differential at the rear.

It features high-pressure direct-injection and BMW’s ‘Valvetronic’ system managing air flow to the intake side, to produce 285kW at a relatively high 5800-6500rpm. But the big punch is 500Nm of peak torque from just 1900rpm all the way to 5000rpm.

The M440i is also a mild-hybrid with a 48-volt starter motor-generator and supplementary battery able to give an 8.0kW kick at low engine speeds.

Rated as a Euro 6d-compliant vehicle, the M240i’s average combined fuel consumption figure is 8.0 litres per 100km, for a carbon dioxide emissions average of 185 grams/km.

With a 52-litre tank brimmed with premium unleaded petrol (98 RON minimum is recommended), that should result in about 650km between refills on average.

Over a mix of urban and highway driving, we managed 8.9L/100km, which is better than the pre-facelift version’s 9.6L/100km. That’s impressive stuff for a performance-orientated sports coupe.

BMW’s official fuel economy figure for the M440i xDrive Gran Coupe, on the ADR 81/02 - urban, extra-urban cycle, is 8.2L/100km, the 3.0-litre turbo six-cylinder emitting 187g/km of C02 in the process.

Stop/start is standard, and we saw an average of 11.1L/100km over city, B-road and freeway running during a week with the car.

With the 59-litre tank brimmed (with minimum 95RON premium unleaded) that real-world test number translates to a range of around 530km.  

The M240i xDrive’s specification reads like it’s straight out of BMW fan fiction.

Nestled within a shrunken 3 Series-derived 'CLAR' platform brandishing near-50:50 weight distribution, stuffed between beefed-up struts up front, is a strident in-line six, driving the rear or all four wheels via an M Sport differential and held up by a multi-link rear axle.

The promise here is an athletic driving machine on one hand and a cosseting grand tourer on the other, but whether the M240i can walk that fickle red line as effortlessly four years on… well, that’s what we’re here to find out. As we said earlier, sub-3.5s Teslas and the like have really messed with the bang-for-your-buck playbook since 2021.

Luckily, the reality only reiterates the 2 Series Coupe’s place in the sun. Rather than the anodyne (or artificial) whine of an electric motor, here instead is one of the greatest modern engines in the world, mated to arguably the best auto transmission ever in existence.

That’s a terrific start. And, once the button is pressed, the M240i’s performance bandwidth is deeply moving and immensely satisfying.

With a kerb weight of 1690kg, the M240i’s power to weight ratio is an impressive 168.6kW/tonne, helping it to scoot from standstill to 100km/h in 4.3 seconds, on the way to an electronically-limited top speed of 250km/h. Note that the M2 flagship is just 0.3s quicker to 100.

Pottering about town in its most benign ('Eco Pro') setting, the B58-hearted Bimmer slinks about gingerly, purring like a content tabby while skimming along over all sorts of urban roads like a luxury car costing a lot more should, taking everything in its stride. Given this is what driving is like for most people most of the time, the BMW nails it.

More throttle unleashes a surging snarl as the BMW’s speed steps up, with varying degrees of urgency according to the driver’s will and desire. Racing up through the gears, the German straight six feels like it has barely stirred; like things are just warming up.

In conjunction with Sport mode, here is where the M240i really starts to take off, leaping into action, engine roaring as speeds soar as if every road is a stretch of derestricted autobahn. The pace of this coupe is quite remarkable. Planted yet precise, the steering firms up as the chassis hunkers down, and you’re left in awe of how calm and composed the car constantly feels. Even in pouring rain.

As the roads start to snake and twist, the BMW glides through the chosen line with startling grip and confidence, without ever feeling nervous or twitchy in standard traction settings, regardless of surface or weather conditions. That’s the AWD doing its thing.

The M240i is all about nuance and control, whether you’re talking steering, handling, roadholding, braking or electronic intervention. It is refreshing to feel so connected to the driving experience so intimately.

As we said back in 2022, plonking for Sport Plus mode, with the stability and traction nannies neutered, is an easy street to big old oversteer spills and thrills, if so desired.

And then, you’re back in Eco Pro, crawling along in cocooned comfort and relying on the ADAS tech to waft you along, before being back in 'Individual' mode as the road ahead clears, with powertrain in 'Sport' but the suspension in 'Comfort'; just right for times when you just want to streak ahead of slower traffic without pummelling your spine. It’s all there for you. The M240i can do it all.

Inevitably, in Sport mode the ride’s firmness can be fatiguing on bad urban roads. Likewise, the tyre noise over coarse bitumen is tiring over longer drives. And it is all too easy to exceed the speed limit.

Earlier, we said we prefer this over the extroverted, track-focused M2, despite the latter’s astounding speed, thunderous soundtrack and tremendous dynamic capabilities, and that’s because of the M240i’s ability to deliver pleasure with everyday user-friendliness. Plus, the performance flagship is only 0.3s quicker to 100.

Maybe the latest base manual M2 might change our minds.

As it stands, on the move, the M240i is BMW in full flight, staying true to brand values but without frying your nerves or depleting your bank account too much. We love it and you should too.

BMW says the M440i xDrive Gran Coupe will accelerate from 0-100km/h in 4.7sec, and I reckon the threshold for a properly quick car is sub-five seconds.

The 3.0-litre turbo six develops its peak power of 285kW between a relatively lofty 5800-6500rpm, but the big number is a solid 500Nm punch of pulling power delivered between 1900-5000rpm.

Squeeze the throttle pedal pretty much anywhere in the rev range and the response is glorious. Rapid acceleration accompanied by raucous engine noise and rorty exhaust note (albeit with some synthetic support). Various pops and bangs in the Sport settings add extra entertainment.. 

The eight-speed auto gets some electric support from the mild-hybrid system to fill the torque gap on up shifts, and the result is a conventional torque-converter transmission that behaves like a dual-clutch.

Shifts are seamless in general driving, and satisfyingly quick in a more aggressive mode, the wheel-mounted paddles dialing up the fun in manual changes. 

Suspension is double wishbone front and multi-link rear with the standard ‘Adaptive M Suspension’ built around an adaptive damper set-up.

The change between the ‘Comfort’ setting to the ‘Sport’ or ‘Sport+’ calibration is close to instant and makes a discernible difference, especially in terms of ride comfort.

I found the best ‘Individual Sport’ arrangement to be damping in Comfort, with the steering engine and transmission in Sport. The car flows so beautifully through corners with urgent response from the powertrain.

By all means dial up the suspension if you’re having a real crack, but the car feels superbly balanced, stable and predictable in Comfort (front to rear weight distribution is 50:50).

The electrically-assisted variable-ratio steering is nicely weighted with good road feel, and the grippy sports steering wheel is a nice point of contact.

The xDrive AWD system’s default setting is rear-biased, although it will push most of the drive forward when required. But the RWD feel is unmistakable. 

The M440i weighs in at around 1.9 tonnes but feels lighter and more nimble than that figure would typically indicate.  

A standard electronically-controlled M Sport limited-slip differential puts the power down confidently. I have a favourite LSD test corner on my regular evaluation drive, a sharply twisting and rising left-hander.

Rolling into it in a low gear before planting the throttle mid-corner, the car simply hunkers down without a hint of fuss (or traction loss) as it rockets out the other side.

Optional M Sport front seats ($2000) provide comfort and firm location in equal measure and in terms of ergonomics BMW knows how to focus on the driver and set-up an efficient environment. Key controls are perfectly positioned and simple to operate.

I have an issue with the ‘Lane Departure Warning’ function, however, which is too quick to intervene and overly intrusive when it does so. I turned the ‘Steering Intervention’ function off. You can dial down steering wheel vibration warnings, too.

The standard M Sport brakes feature big vented rotors front and rear, with fixed four-piston front calipers doing the bulk of the work. They’re strong but don’t bite or release too aggressively. It’s easy to grease in a smooth application. 

Active crash-avoidance tech in the M440i xDrive Grand Coupe is impressive with AEB standard, as well as lots of assistants and warnings, namely: ‘Steering and Lane Control Assistant’, ‘Cross Traffic Warning’ (front and rear), ‘Lane Keeping Assistant’ (with ‘Lane Departure Warning’ and ‘Lane Change Warning’), ‘Crossroads Warning’, ‘Evasion Assistant’, and ‘Parking Assistant Plus’ (including ‘3D Surround View and Reversing Assistant’).

If an impact is unavoidable there are six airbags on-board (driver and front passenger front and side, plus side curtains) as well three top tethers and two ISOFIX positions for child seats in the second row.

Plus an ‘Intelligent Emergency Call’ function automatically dials back-to-base if the car has been involved in a crash, and a comprehensive first aid kit is on-board. 

The BMW scored a maximum five-star ANCAP assessment in 2019.

BMW offers a five-year/unlimited kilometre warranty, matching all of its German rivals, as well as three years of roadside assistance.

As always, servicing frequency is condition-based, depending on how they’re driven, amongst other factors, with an indicator on the instrument panel to alert the driver/owner. That said, our advice is to always visit your BMW dealer annually or at every 10,000km, just to be certain.

Capped-price servicing is not offered.

However, the ‘BMW Service Inclusive Basic package’ is available at extra cost, covering scheduled servicing for five years/80,000km, as long as the scheme is subscribed to before the end of the first 12 months of first registration. A 2 Series should cost from $2380.

The M440i Gran Coupe is covered by BMW’s three-year/unlimited km warranty (including paintwork), as well as 12-year/unlimited km anti-corrosion (perforation) cover. 

That’s off the premium market pace now with Genesis, Jaguar, and Mercedes-Benz at five years/unlimited km and Lexus set to join them from January 1st, 2022. 

That said, roadside assistance is provided for the duration of the main warranty, but it’s worth noting “rattles and squeaks” are only covered for one year.

Service is condition-based, the car telling you when maintenance is required, and a range of service packages are available. The basic plan covering a 4 Series for five years/80,000km comes in at $1750.
