BMW M140I vs BMW M240I

What's the difference?

I’m the first to say the 1 Series is kind of the ugly duckling of the BMW family, but those looks grow on you, especially when you consider that this is exactly what a BMW hatch should look like. That this is one of the only rear-wheel-drive hatches left on the planet makes it even more special – and of course engaging to pilot. The downside is the price and the lack of value from a features perspective, plus safety could be bolstered with more technology. Still, anybody who likes to drive will commend you on your choice of a BMW.  

When BMW is on a roll, the world needs to watch out.

And, as our Thundernight metallic-hued M240i so literally demonstrates, its purple patch continues after a string of modern marvels like the latest 4 Series and iX, distilling the essence of compact sports coupe and luxury cruiser with dizzying confidence.

Joining the pantheon of back-catalogue greats like the 2002ti and 330Ci, we're missing it already now that the keys have been returned. Isn't that the true sign of the quintessential BMW experience?

The 1 Series looks exactly how a BMW hatchback should. I know that sounds silly but what I mean is BMW could easily have designed something that was proportioned more like other hatches; that popular sort of bubble on wheels.

Instead, what you have is a hatch that retains BMW’s traditional attributes – there’s the long nose, the cabin set back, the high sides and the wheels placed almost at the very corners.

Seriously, look at the image of the orange 1 Series side on, now hold your out your hand and use it to cover just the windows – see, it looks just like a BMW 2 Series convertible. Does it look good? To me it does, right up until you get to the hatchback, and then it looks a bit awkward. But I do admire BMW’s designers for creating something unique looking.

That orange 120i ('Sunset Orange' is the official colour) is the most recent 1 Series I’ve tested. Those wheels aren’t standard, they’re 18-inch M ones and they are part of the optional 'M Sport Package', which also includes the body kit, complete with side skirts and the lower grille in gloss black.

The 1 Series is as affordable as BMWs get, but it’s still a real BMW. The cabin, for example, looks much like  every BMW, only smaller.

There’s the large, slab-like dash with the display sitting atop, below are the air vents and below that is the radio and then the climate-control dials. It’s a stack that’s kept its familiar order and shape on nearly all BMWs for what seems like forever.

The centre console has a similar layout as the one in a 3 Series or 5 Series or any Series, with the shifter and rotating media controller. Even the doors have the same design as those cars higher up in the BMW family, with the big moulded pockets and large pull handles.

The cabin isn’t as ‘blingy’ as the new Mercedes-Benz A-Class, but it’s not as plain as the Audi A3.

That steering wheel is part of the M-Package too, but the leather upholstery is a separate option.

The signs that this isn’t a more expensive BMW are the manual handbrake, the compact instrument cluster with analogue dials, the small dash-top display and the fact that  there’s a lot less real estate to be covered by trim pieces and material, which doesn’t have the same high-quality feel as those fancier models.

The cabin isn’t as ‘blingy’ as the new Mercedes-Benz A-Class, but it’s not as plain as the cockpit of an Audi A3 – it’s somewhere in between; refined and well designed.

At 4.3m end to end, the 1 Series is 16mm shorter that the A3 Sportback and 20mm narrower, at just over 1.7m across.

What is happening with BMW design? It's as if the Germans have run out of ideas.

Though we're eternally grateful it exists, the G42 is the least pretty of the three 1 and 2 Series coupe generations, as well as the most aggressively styled. All the usual macho tropes are present – cab-backward long-bonnet/short boot silhouette with an exaggerated dash-to-axle ratio, huge front air intakes, bulging bonnet and diffuser-heavy rear end.

There's also a beady eyed look to this M240i, with its squinty headlights and angry tail-light shapes further piling on the attitude. It's a far cry from the simple elegance of the E82 original, let alone the classic E30 of the Eighties. We wonder how much extra the M2 version will be when it surfaces later on.

That said, the G42's design is in keeping with something wearing an M-something-something prefix. In the optional purple of our press car, it certainly turns heads. That said, in the Bangle era, BMWs didn't have to rely on paint to do that.

Bangle, by the way, refers to BMW's late '90s/early '00s head designer Chris Bangle, an American with a bold aesthetic, scant regard for tradition and a taste for the controversial. His effect on vehicle styling, starting with the 2001 7 Series, is still felt today.

Dimensionally speaking, comparing the length/width/height/wheelbase measurements of the M240i (4548mm/1838mm/1404mm/2741mm) with a 2000 E46 330Ci (4488mm/1757mm/1369mm/2725mm) shows how today's coupe is palpably larger.

Over the previous (F22) 2 Series, the newcomer is 105mm longer, 64mm wider and 28mm lower; the wheelbase has been stretched by 51mm, while the front and rear tracks are 63mm and 35mm further out, respectively. Result? More space inside for today's lucky occupants.

The 1 Series’ boot has a cargo capacity of 360 litres, which is more than the boot space of the Audi A3 Sportback (340 litres) but less than the new Mercedes-Benz A-Class’s 370 litres of luggage room.

What does that mean in real-world terms? It’s not a lot of space, and you might struggle to get a pram in, so check that  beforehand if you have small ones. That said, there was enough room for two carry-on sized bags, a computer bag and a scooter when my wife and I went on a weekend away with our four year old.

Space in the second row is also limited. Headroom isn’t too bad, but at 191cm tall I can’t sit behind my driving position without my knees digging into the seatback. I can just fit back there in the A3 and I have even more room for my knees in the A-Class.

Room up front is good with plenty of shoulder, head and elbow room for somebody my size.

Storage could be better: you’ll only find cup holders up front (two of them), the centre-console storage bin is small and so are the door pockets in the rear, but all is not lost because the door bottle holders in the front are massive, the glove box is a decent size and there are nets on the backs of the front seats.

It’s good to see directional air vents in the second row and a 12V power outlet, but there aren’t any USB ports back there – if you want to plug in a device there’s only one and it’s up front, along with another 12-volt outlet.

The rear doors appear large from the outside but the aperture to get in and out isn’t huge – again look at the images to see what I’m on about.

Interior dimensions may not be paramount to most coupe purchasers, but a stylish one with quality fittings and generous equipment levels certainly is, and here the M240i is bang-on brand.

For a compact two door, the M240i is pleasingly accessible. Long doors and a tallish roof help entry/egress, into a 2+2 cabin that obviously prioritises front-seat occupants. And it does that exceedingly well.

There's space to stretch – even if you're two metres tall – up front, as long as the rear seats aren't occupied, as a result of generous leg and shoulder room, while headroom should also be sufficient, even with the sunroof fitted. We're talking about a small coupe, remember, so that's impressive.

Vision out isn't as bad as you might imagine, either, due to the airiness that the elongated side windows provide. There are blind spots, though, with the B-pillar being the worst, but at least the extensive camera and sensor network surrounding the car provide reassuring back-up.

The handsome M Sport front seat option ($2000 extra) look like they mean business, providing all the comfort, support and adjustment most occupants will ever need. They're firm enough when you need them yet restfully supple all the time. Backed up by a multitude of electronics, both buckets will brace people of pretty much all sizes, while the driver has the luxury of two memory settings that also take in mirror positions.

Remember how the new 2 Series comes via Mexico? You'd never know it wasn't built in Germany, from the solid build quality and expensive materials to the extremely welcome absence of squeaks and rattles. No area exposed to the occupants looks or feels cheap.

Also meeting expectations is the dashboard itself, which is essentially a scaled-down replica of every recently released BMW – futuristic and fabulous iX aside – since the current (G20) 3 Series in 2018 broke the Bangle-era curse of disappointing new-millennial models.

If you're hoping for a return to classic analogue instrument dials, forget it. The M240i's instruments are modish electronic items, providing plenty of vehicle and driving data, and supported by an excellent head-up display. Like the switches and buttons, they're easy to fathom, with little familiarisation required.

As we've said repeatedly in other BMW reviews, the iDrive multimedia controller is amongst the best in the business, responding instantly to inputs. The other basics – ventilation, storage, driving position – are also first class. Nothing to complain about here. The company is on a good thing and it's sticking with it.

Accessing the rear seats is aided by electrified front seats that slowly whir forward, to provide a big-enough aperture for your medium-build 178cm tall tester to squeeze in.

Once sat, with legs splayed apart, there's just enough space for another person of similar height and proportions, as well as surprisingly decent levels of vision thanks to the narrow front bucket seats and extended rear glass area, to offset any feelings of claustrophobia.

BMW has also provided several welcome amenities, including face-pointed rear vents with full single-zone temperature control to serve two occupants back there, armrests (with the centre fold-down item also packing in a pair of cupholders), reading lights and coat hooks.

Sadly, however, the rear windows do not retract, and the thick door pillars are fixed, so you cannot enjoy a pillarless hardtop experience. That's what the M4 coupe (and convertible too) is for.

While rear-seat space is adequate, with enough room for shoulders, thighs and feet if the front-seat occupants don't mind raising the cushion a little, the backrest is too upright to be considered comfortable on longer journeys. At least the low cushion is scalloped enough to provide some support, though, again, not over extended periods.

That rear backrest folds, by the way, to a 40/20/40 split, providing access into the 390-litre boot while still able to accommodate a single passenger. The lid opens up and wide, offering up a long, flat and wide space for storage. Along with a 12V outlet and tie-down hooks, you'll find a tyre-repair kit, since no spare wheel is carried.

Don't worry. Even though the latest, third-gen 1 Series hatch as well as five-door versions of the 2 Series have sacrilegiously gone all transverse-engined and front-wheel drive on us, BMW knows not to cook the golden goose or poke the bear by retaining the traditional longitudinal/rear-drive set-up for the G42.

For car enthusiasts, that was one of the few pleasant surprises of last year.

Hailing from a new BMW plant in Mexico, the 2 Series coupe comes in two flavours for now: the 220i from $61,900 before on-road costs, and the M240i from $89,900 before ORC. Other grades like a 230i are likely to follow soon.

Both models are decently specified, sharing LED headlights and tail-lights, auto start/stop, paddle shifters, an M Sport Package (including a multifunction steering wheel, selectable driving modes, sports seats and anthracite headliner), M Sport suspension, variable sport steering, 'Hey, BMW' driving assistant, head-up display, auto parking assistance with a surround-view camera, a 12.3-inch instrument display, a 10.2-inch control display, digital radio, wireless smartphone integration, Apple CarPlay/Android Auto connectivity, emergency services access, three-zone climate control, rain-sensing wipers, electric heated/folding exterior mirrors, through loading into boot with remote-release backrests, ambient lighting and tyre-repair kit in lieu of a spare wheel.

However, the differences between the two already on sale here are extensive, starting with the M240i gaining a 3.0-litre inline six-cylinder (I6) turbocharged petrol engine in lieu of the 220i's 2.0-litre four-cylinder turbo petrol unit.

There's also all-wheel drive (AWD) for the first time in a 2 Series in Australia, as well as M Sport suspension with adaptive dampers, an M differential, M Sport brakes, body kit, adaptive cruise control with full stop/go functionality, keyless entry/go via BMW Digital Key, electric sunroof, leather instead of Alcantara/artificial leather upholstery, electric front seats with driver's side memory and heaters, adaptive LED headlights with auto high beams, 14-speaker Harman/Kardon surround-sound audio system and 19-inch alloy wheels, among other items, to help justify the extra $28,000.

Standard safety features include six airbags, forward collision warning, Autonomous Emergency Braking (AEB) front and rear, with front/rear cross traffic alert, lane departure warning with passive steer assist, lane keep with active assist, blind spot monitor, 360-degree view cameras, parking assist, parking sensors and road-sign recognition, among other features. More details in the safety section below.

With two-door coupes falling out of favour, four-seater performance rivals to the M240i Coupe include the Ford Mustang GT V8 (from $64,190) and Audi TT S quattro (from $104,500), while there are various two-seater options like the coming Nissan Z (pricing TBC, but the outgoing 370Z kicks off from just $50,490), Toyota Supra (from $87,803) and Porsche 718 Cayman (from $115,900).

Thinking more laterally, the $92,900 Audi RS3 and $99,895 Mercedes-AMG A45 S hyper-hatches are quicker while the Tesla Model 3 Performance Dual Motor sedan from $88,900 will blow the BMW away for performance, so if you don't strictly need coupe style, then the M240i does cop some unexpectedly stiff competition at its price point.

Still, few rivals balance the pricing, packaging, performance and AWD capability with the swagger of our purple coupe, which makes this 2 Series quite a unique value proposition in its own right.

As you step up through the grades the engines become more powerful. The entry-grade 118i has a 1.5-litre three-cylinder turbo-petrol making 100kW of power and 220Nm of torque, while its diesel twin has a 2.0-litre turbo-four making 110kW and much more torque at 320Nm.

The 120i has a 2.0-litre turbo-petrol four-cylinder and an output of 135kW and 270Nm. Then above that is the 125i, which is getting into performance territory with its 2.0-litre turbo four petrol making 165kW and 310Nm.

But all hail the M140i and its beautiful 3.0-litre six-cylinder turbo-petrol, with 250kW and 500Nm that it wants to share with you.

All cars are rear-wheel drive and all have an eight – hang on, that’s important: all cars are rear-wheel drive. Do you know how many other hatchbacks are rear-wheel drive? Try next to none – not the A-Class, not the A3, not the Golf. Rear-wheel drive is favoured for performance cars because it offers better balance and better acceleration thanks to the weight shift to the rear of the car. BMW has long claimed that RWD is one of the keys to its "sheer driving pleasure".

Now let me finish the sentence... all have an eight-speed automatic, and it’s a beauty – a little slow, but smoother for driving than a dual clutch, and way more fun than a CVT.

But wait, because there’s a manual gearbox, too. It’s a no-cost option and you can get it on any variant apart from the 125i.

As with all of our current favourite BMWs that aren't electric on full-fledged M cars, the M240i is fitted with a variation of the divine B58 engine – a 2998cc 3.0-litre double overhead cam direct-injection turbo I6. It delivers 285kW at a heady 6500rpm, and 500Nm of torque between a low 1900rpm and 5000rpm.

A kerb weight of 1690kg (200kg more than the 220i equivalent) means the M240i's power to weight ratio is about 169kW/tonne, which may explain why it can manage the 0-100km/h time in 4.3 seconds. V-max is 250km/h.

Power is channelled to all four wheels continuously via an eight-speed M Steptronic transmission, while the AWD system features a differential to help transmit torque to all four wheels more cleanly.

Controlling all those outputs, the M240i's suspension consists of a two-joint spring strut front and a five‑link rear axle arrangement, with M Sport suspension including variable sport steering, additional front axle struts, M Sport brakes, M Sport differential at the rear axle and adaptive M suspension with electronically controlled dampers.

BMW says its most efficient petrol engine in the 1 Series range is the three-cylinder in the 118i, which uses just 5.2L/100km after a combination of urban and open roads.

The diesel unit in the 118d will use 4.2L/100km. Let that sink in for a moment – petrol engines are becoming so fuel efficient that they’re rivalling diesels, which have long been lauded for their frugality.

So don't just buy the diesel just because it’s more efficient, because you may never recoup the extra money you paid over the 118i.

Thirstier but still super-efficient is the 2.0-litre in the 120i. BMW’s claim is 5.9L/100km. During my week with the 120i I put 413km on the clock and used 15.57 litres doing so (measured at the pump), which comes to 7.7L/100km. The car’s computer said 7.8L/100km.

That’s great fuel economy, even if it is higher than the claimed figures. The 125i’s official fuel consumption is also 5.9L/100km.

It’s not surprising that the M140i, with its 3.0-litre six-cylinder turbo-petrol engine, is the least fuel efficient but its official figure of 7.1L/100km is still low.

Over exactly 503km of city, suburban, freeway and performance testing, we managed a credible 9.6 litres per 100km – and that was with the air-con on  constantly and regular visits to the 7000rpm rev limiter. No horses were spared in our quest to properly assess this vehicle.

BMW's official combined-average claim for the Euro 6d-rated M240 is 8.0L/100km flat – and 6.6L and 10.3L in the Extra Urban and Urban runs – for a carbon dioxide emissions average of 185 grams/km.

The small fuel tank swallows just 52 litres of E10, 95 or 98 RON (as tested) premium unleaded petrol, meaning an average of 650km between refills is possible.

If I could run into a showroom and take whichever 1 Series I wanted it’d be the M140i – and not just because it would give me the best chance of outrunning the police after they discovered the break-in, but because the thing is so much fun to drive.

It’s also the most expensive, of course, but it’s worth it for that screaming straight six and for its agility.

You’ll have fun, though, in every grade of the line-up – they’re all engaging to pilot with great driving positions, good pedal feel and that eight-speed auto is smooth in traffic yet will shift hard when you have your race face on.

You might find the 118i, with its three-cylinder, a little under powered, especially with five people and their bags on board. If you’re keen on this grade, then consider the diesel, which will give you more torque. Our 120i test car proved to have enough oomph for overtaking and moving quickly when needed.

The 125i is less tame, with its throatier exhaust note, firmer ride and better handling thanks to the M suspension.

If you plan on choosing the M Sport Package for, say, the 120i keep in mind that you’ll lose the comfortable ride these cars have on their standard tyres.

Our 120i had the pack and while the body kit looks tough, the 18-inch alloy wheels shod in low-profile rubber (225/40 R18 Bridgestone Potenza 5001s front and 245/35 R18 at the rear) meant the ride was overly jarring on bad roads.

Given that Sydney was my test bed for the 120i and its roads are shocking, the ride was less than comfy. The M-sport suspension will only make the ride less comfortable, but in return you’ll have a 120i with better handling.

Run-flat tyres are common on BMWs and you may have heard of a few issues surrounding noise and a harsher ride. While that can be true, it's the price you pay for having a tyre you won’t immediately have to change if you get a puncture. Only the 120i and the M140i don’t have run-flats as standard.

In a word, invigorating.

Stuffing a big old engine in a little-ish car is always an exciting recipe for thrills, and the M240i Coupe does not disappoint.

Press the start button, and the sublime B58 3.0-litre turbo I6 growls into life, setting a rich tone for the level of performance as well as sophistication that's coming.

Even in Eco mode, off-the-line acceleration is stirring, with a hefty shove if you're in a hurry, or a brisk pace if you just long to just take it easy, defined by smooth upshifts from what remains one of the world's greatest-ever automatic transmissions.

That said, Normal is the default operating setting, and here the M240i can take on a Jekyll and Hyde split-personality, that goes well beyond simply possessing a strong throttle response accompanied by a soaring exhaust note. The engine sings sweetly even right up to 7000rpm, while the gearbox is uncanny in its ability to always be in the correct gear, yet will simultaneously hold each ratio in manual mode (via the shifter or paddles) if the driver needs to go hell-for-leather.

Speaking of which, in Sport mode, the 3.0-litre turbo goes into red alert, taking on a louder and more muscular mood, as it roars along with frenetic yet effortless speed. What seems like 90km/h can, in fact, be very much more, and with plenty of extra oomph in reserve.

It's so typical BMW that purists affronted by some of the brand's other niche offerings of late will cry with joy that the art of making a sports coupe has not been lost in Bavaria after all.

And that's before the first turn of that fat little steering wheel. Here the 2 Series Coupe's 3 Series-derived CLAR architecture's DNA is immediately obvious, providing subtle balance and an immersive connection to go with all that bolshy brawn.

The M240i will glide along precisely where pointed, sticking steadfast to the tarmac while cornering at speed without breaking a sweat. That mechanical rear diff helps provide both alacrity and reassuring control. Yes, it remains weighty and planted when punted relentlessly through tight corners, but it's also not as heavy-feeling as before.

Being AWD, there's grip galore to rely on for security, yet the M240i still seems deliberately rear-drive biased in its set-up, so the driver can hang the tail out if wanted with gradual ease in Normal, or with a little more of a sideways flick in Sport. The modes are configurable so the level of engine, steering and suspension responses can be tailored as desired, meaning that in the racy Sport Plus setting, with stability and traction controls on hold, the full oversteer experience is possible if you're game/brave/silly enough.

This car's brilliant performance is also down to incredibly dependable and nuanced braking, adding another layer of driver enjoyment, since it can pull up hard and fast if need be without drama or fuss.

So, it's no surprise to learn that an M-Sport-enhanced BMW can be a deliciously fast and limber along a mountain road.

But the real progress over the old F22 is just how suave and polished the G42 is if you're tired and stressed, isolating its occupants from the rigours of rubbish road surfaces. Kudos to the 'Adaptive M Suspension' and its adaptive dampers for this, for they're standard M240i fare. The resulting cushy ride completely broadens the dynamic bandwidth of this compact sports coupe, making it an everyday commuting proposition.

Ultimately, it's a bit of a struggle to find fault in the 2 Series' drivability and dynamic make-up. The usual Euro luxury car bugbear of too much coarse-chip tyre noise applies, but as this is a sports coupe, that's not such a big deal here. Even wind noise levels are subdued – all the better to drink in that glorious turbo engine wail.

BMW, you got the M240i delightfully right.

There is no ANCAP rating for the BMW G42 M240i Coupe, but over at EuroNCAP, a 2022 220d coupe scored just four out of five stars.

Areas singled out needing improvement include better pedestrians/vulnerable road user protection (especially for cyclists) and a 'marginal' rating for the emergency lane keeping's effectiveness.

Standard safety features includes six airbags (dual frontal, side chest and head-protecting airbags for the first row and side chest protecting airbags for the second row), forward collision warning, Autonomous Emergency Braking (AEB, operational from 5km/h to at least 210km/h and with cyclist and night-time operation), front/rear cross traffic alert, lane departure warning with passive steer assist (operational from 70km/h), lane keep with active assist, blind spot monitor, driver attention monitor, 360-degree view cameras, parking assist, parking sensors, anti-lock brakes with electronic brake-force distribution and brake assist, stability control, traction control, corner braking and rain-sensing wipers.

There are also two ISOFIX points as well as two top tethers for straps in the rear seats.

The 1 Series is covered by BMW’s three-year/unlimited kilometre warranty. Servicing is condition-based – the car will let you know when it needs a check-up.

BMW offers two service packages, which cover the car for five years/80,000km: the Basic is $1340 and the Plus costs $3550.

Trailing all of its main luxury car rivals (except Porsche) by two years, BMW only offers a three-year/unlimited kilometre warranty, as well as three years of roadside assistance.

BMW says its vehicles' servicing is condition-based, depending on how they're driven and other factors, with a dash warning appearing to let the driver/owner know when it's time. We advise servicing your M4 annually or at every 10,000km

No capped-price servicing system is offered. However, as long as the first one is paid for before the first service on a new vehicle, the 'BMW Service Inclusive Basic packages' is available at extra cost, covering scheduled servicing for three years/40,000km or five years/80,000km. A 2 Series should cost from $1700 for the five-year/80.000km package.
