BMW 6 Series vs BMW 2 Series

What's the difference?

This isn't a car for everyone's tastes, but if you fit in to the buyer group that just doesn't really know what they want in a luxury car, it could be the perfect fit for your family. The 6 Series GT is a practical large prestige car, albeit one that will likely find very few buyers.

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.

There is no denying the 6 Series GT looks better than the old 5 Series GT. It isn't as frumpy, it looks more sporty, and to me it appears to have grown into its identity with more conviction than its predecessor.

That said, I don't necessarily like the look very much - it's a bit like a BMW X6 that has been rounded off a little and lowered down substantially. But I can appreciate some of the finer design aesthetics that it offers up: the frameless windows are a nice touch, and the swooping roofline looks smoother than a duck's back.

Other things like the active grille shutters and the air breathers ahead of the front doors are nice functional touches, and to my eye it lives up to BMW's hope of it looking "smooth but muscular". You can get the 630i with either the M Sport package, like you see here, or the more sedate Luxury Line, which is, well, more luxurious looking.

The M Sport styling and equipment package you see in the images here - with M aero kit and 19-inch wheels (ours had been upgraded to optional 20s) - help out with the athletic look of this very big vehicle.

It's huge in fact. The length of the 630i is 5091mm long, it measures 1902mm wide and sits at 1538mm tall, with a lengthy 3070mm wheelbase.

All that equates to a lot of room in the cabin, and what a sumptuous and delightful place it is to be - leather, wood and plush finishes abound.

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.

Now, I said before that this is a bit like an X6, but it has heaps better interior space than that SUV.

As soon as you slide into the driver's seat, you feel like your inside a large car. The cabin space is plentiful, and there's an abundance of storage on offer, too: there's a split-lid armrest between the seats, a pair of cupholders, a phone storage nook with wireless charging, and big door pockets with bottle holsters.

In the back you have access to door pockets, a flip-down armrest with cupholders (that middle part of the seat can fold down completely to allow storage of longer items), and there's excellent room on offer. How many seats in the BMW 6 Series GT? Five - like, five full-size seats.

Because the roofline doesn't rake as sharply as a four-door 'coupe', headroom is excellent for adults (even of the 183cm variety, like myself), and legroom and toe room are equally very good. This is bigger in the back than a 5 Series, but maybe not as plush as a 7 Series… so I guess it makes sense numerically for its nomenclature.

Of course you get climate control in the front (and in the rear if you option it), and the materials are excellent. The media screen is tablet-style, proudly displaying 10.25 inches of high-def real estate that is both touch-capacitive and controllable by way of the central rotary controller with touchpad. And get this - you can even use gestures to control certain elements like volume, swiping and changing tracks… but you have to option that.

The fully digital instrument display is bordered by a set of incomplete dial rings, which is just odd. BMW, back yourself - your buyers can handle just having a digital screen in front of them, particularly when it's as good as this one.

This grandiose hatchback's boot is commodious - with the back seats in place it has a huge 610 litres of cargo capacity, which extends to 1800L with the 40/20/40 seats folded down using the quick release levers in the boot area.

There is no spare wheel (the BMW range is fitted with run-flat tyres) but it does have a secondary hidden storage area under the boot floor for hiding items or stowing wet gear, bathers/swimmers or muddy clothes.

For context, the X6 has 580L seats up, 1525L seats down.

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.

The good news is, the G42 in 230i and flagship M2 retain the traditional longitudinal-engined/rear-wheel drive set-up, though the M240i has all-wheel drive (xDrive in BMW-speak) to help keep things under control.

All the other existing 2 Series models (basically, those with more than two doors) are transverse/FWD-derived.

Now, the bad news is that, from $102,100 (all prices are before on-road costs), the M240i is considerably more expensive than before. You can no-longer buy a traditional six-cylinder BMW coupe for under six figures. The continuing 230i Coupe, from just under $80K, uses a (albeit lovely) four-pot turbo.

At least the Mexican-made M240i isn’t short of equipment.

You’ll find an 'M Aerodynamics' package, 'M Sport' package that includes drive modes, M suspension with adaptive dampers, M brakes, M differential, M variable steering and M… more.

Additional items include adaptive LED headlights, leather upholstery, electric and heated sports front seats with driver’s side memory, climate control, sunroof, adaptive cruise control, paddle shifters, a 12.3-inch instrument cluster, a 14.9-inch multimedia display, 'Hey, BMW' voice control, a heated steering wheel, a head-up display, auto parking, a surround-view camera, 14-speaker Harman Kardon audio, digital radio, wireless charging, Apple CarPlay/Android Auto, emergency services access as part of a three-year subscription, electric heated/folding M exterior mirrors, ambient lighting, 19-inch alloy wheels and a tyre-repair kit ­– in lieu of a spare wheel.

Our car as-tested also included 'Brooklyn Grey' metallic paint ($1700), 19-inch M light alloy wheels with performance tyres ($2800) and the M Sport Package Pro material/trim package ($1900), helping to bump up the price to $108,500. No reversing nearside mirror-dip is a bit stingy, though.

Still, there’s also a decent wad of advanced driver-assist systems, including AEB front and rear, lane-support tech and various monitors. Read more about that and more in the safety section below.

The near-$20K price jump since 2022 also means the M240i is now more expensive than the Z Nismo and Mustang Dark Horse and is now rubbing shoulders with the (BMW-based and built) Toyota Supra Track Edition and even the MG Cyberster Dual Motor.

And, speaking of electric vehicles, as before, the now-$81K Tesla Model 3 Performance’s astounding 3.1-second acceleration is in another league.

No, the M240i is about traditional BMW values harking back to 'The Ultimate Driving Machine' era. Premium, driver-focused German grand touring sports luxury coupe, cabriolet or convertible.

From that perspective, the two-door 2 Series is the cheapest by a fair margin and in a league of its own.

Under the bonnet of the 630i is a 2.0-litre four-cylinder turbocharged petrol engine, which produces 190kW of power (at 6500rpm) and 400Nm of torque (from 1550-4400rpm). It uses an eight-speed automatic transmission, and is rear-wheel drive.

That may not seem a lot considering the size of this machine, but consider that some of the steamiest four-cylinder hot hatches have nearly the same outputs, and you realise this engine offers up a far-from slouched approach to propulsion.

The 640i xDrive has a 3.0-litre six-cylinder turbocharged engine with 250kW of power and 450Nm of torque. It gets the same eight-speed auto, but as the xDrive naming indicates, it's all-wheel drive.

But this is the one you'd prefer if you want to hit highway speed in a hurry - the 0-100km/h claim is 5.3 seconds, where the 630i takes a full second longer (6.3sec) according to the company.

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.

BMW claims fuel use of 7.0 litres per 100 kilometres, and you'll need to use 95RON premium unleaded when you fill up.

On my trip with the car, I saw about 9.0L/100km across mostly high-speed driving - some freeway, some highway, some country back road touring, and quite a bit of corners and city stuff thrown in as well. I think that's pretty respectable.

What wasn't so great was the lack of premium fuel in some of the 'away from civilisation' places on my route home. Keep that in mind if planning your own GT long-distance cruise.

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.

I'll put this out there - if you like to drive, there are BMW models for less than this one that will put a much bigger smile on your face. Like, a 440i Gran Coupe, or even just a 330i sedan…

But if you're in BMW's target market - that being older executive buyers who want space and luxury as a priority over thrills at the wheel, you could do a lot worse.

That's because the 6 Series GT lopes along the highway without fuss - the engine easily coping with the demands of overtaking moves, the adjustable drive modes allowing a light steering and wafting suspension feel to wile away the kilometres.

There are 'Comfort' and 'Comfort Plus' modes, but the latter is a bit too spongy and can be boaty feeling. The Comfort setting is made for the highway.

It is actually pretty agile for its dimensions.

If you decide to deviate from the straight sections, you'll be able to explore a little bit of dynamic range, especially when you dial up the 'Sport' mode, which changes the damper settings, steering weight, throttle and transmission response, and even the digital dials in front of the driver to a more aggressive look.

Our car had the 'Integral Active Steering' setting, which is a variable ratio steering system that includes rear steering - that essentially helps make is more turnable in corners at highway speed, and easier to park at lower speeds. It's difficult to say whether the assistance is excellent or not short of driving a car without the tech, but to this tester it was hard to hide the size and weight (1835kg kerb weight) of the vehicle.

That isn't to say it's clumsy or lumbering - it is actually pretty agile for its dimensions, though it makes a lot more sense on long drives and coastal cruises than it does in the narrow and twisty alpine roads of the Snowy Mountains Highway that I tested it on.

There's good grip from the tyres, and strong response from the powertrain - but if it were my money, and I had to have a 6 Series for whatever reason, I'd be looking towards the 640i model, which has a thumping six-cylinder with 250kW/450Nm - certainly an engine that would be more at home in this car. Plus that model comes with AWD.

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.

No ANCAP rating exists for the G42 M240i Coupe in Australia.

However, a 220d diesel coupe (not available here) tested by Euro NCAP back in 2022 managed a four- out of five star result, with pedestrians/vulnerable road user protection and emergency lane keeping recommended for improvement.

The MY25 M240i comes with a raft of advanced driver-assist systems, including AEB (operational from 5.0km/h to at least 210km/h and with cyclist and night-time operation), forward collision warning, front-cross and rear-cross traffic alert, 'Rear Collision Prevention', 'Speed Limit Information', lane departure warning with passive steer assist (operational from 70km/h), lane keep with active assist, blind spot monitor and driver attention monitor.

It also comes fitted with 360-degree view cameras, parking sensors, anti-lock brakes with electronic brake-force distribution and brake assist, stability control, traction control, corner braking and six airbags, made up of dual frontal, side chest and head-protecting airbags for the first row and side chest protecting airbags for the second row.

Speaking of the back seat, a pair of ISOFIX points as well as two top tethers for securing child seats are present.

BMW runs a condition-based servicing plan, which means the car will tell you when it needs servicing. But you can rest assured it won't (theoretically) cost you much, with the brand's 'Service Inclusive' pack. It covers you for basic maintenance as and when required for five years/80,000km. According to BMW, that includes "annual vehicle checks, oil changes, all filters, spark plugs and labour costs for the duration of the package".

BMW offers a three-year/unlimited kilometre warranty plan, and you get the same cover for roadside assistance.

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.
