Rolls-Royce Ghost VS BMW 6 Series
- Unbelievable ride comfort
- Flawless quality
- Understated design
- Numb steering
- Vast turning circle
BMW 6 Series
- Heaps of space
- Feels plush
- Good standard equipment
- Feels big on the road
- A bit of a weird car, really
Rolls-Royce says its out-going Ghost is the most successful model in the company’s 116-year history.
No bad, when you consider the first ‘Goodwood’ Ghost has ‘only’ been around since 2009. And although the factory isn’t quoting specific numbers, that all-time best-seller claim means it’s surpassed the more than 30,000 Silver Shadows produced from 1965 all the way through to 1980.
Unlike the brand’s Phantom flagship, the Ghost is designed for owners who want to drive, as well as be driven. The aim is a less conspicuous, more engaging experience, and according to Rolls-Royce Motor Cars CEO, Torsten Müller-Ötvös, development of this new generation Ghost involved a lot of listening.
He says a team of “Luxury Intelligence Specialists” connected with Ghost owners around the globe to gain a clearer understanding of their likes and dislikes. And the result is this car.
While its predecessor’s engineering DNA included more than a few strands of BMW 7 Series (BMW owns Rolls-Royce), this all-new car stands alone on an all-RR alloy platform also underpinning the Cullinan SUV and Phantom flagship.
The factory claims the only parts carried over from the prior model are the ’Spirit of Ecstasy’ ornament on the nose, and the umbrellas slipped into the doors (the holders for them are heated, by the way).
We were offered the opportunity to slip behind the wheel for a day, and the experience was a revelation.

BMW 6 Series
What happens when you struggle to sell an odd-bod, not-quite-a-coupe, sort-of-a-hatchback, almost-an-SUV model? Well, sometimes it gets axed, and replaced with a new model that bears a new name.
That's pretty much it in a nutshell for the BMW 6 Series Gran Turismo, which was formerly the 5 Series GT. It essentially takes the place of the 6 Series Gran Coupe - an alternative to the regular 5 Series sedan that's more attainable than a 7 Series limousine.
Confused? It's not as difficult as all that sounds - you just need to know that this model, the 2018 BMW 6 Series Gran Turismo, is supposed to offer a neat alternative to the go-to family luxury car or SUV.
I spent some time in the entry-level 630i to see if it can deliver on that promise. In fact, I spent more than 24 hours driving the BMW 6 Series GT over the past week, and I don't have a sore back, I haven't been left scratching my head over the intended purpose, I haven't been uncomfortable, and I haven't been left wanting for much.
|Engine Type||2.0L turbo|

You might see it as an obscene indulgence or a piece of engineering excellence, but there’s no denying the new Rolls-Royce Ghost is exceptional. Incredibly refined and capable, it’s arguably the most impressive ‘entry-level’ car in the world.
BMW 6 Series7.6/10
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.
Would you consider a genre-bending car like the BMW 6 Series GT? Let us know in the comments section below.
Rolls-Royce adopted what it calls a ‘post-opulent’ philosophy in development of the new Ghost’s design. Specifically, restraint, “rejecting superficial expressions of wealth.”
That’s because, as a rule, Ghost customers aren’t Phantom customers. They don’t want to make that big a statement, and prefer to drive the car as much as they might be chauffeured in it.
This Ghost is longer (+89mm) and wider (+30mm) than the outgoing model, yet it’s a superbly balanced shape, with minimalism the guiding design principle.
That said, the iconic ‘Pantheon Grille’ is bigger, and now downlit by 20 LEDs under the top of the radiator, with its individual slats polished even more carefully to subtly reflect the light.
The car’s broad surfaces are tightly wrapped and deceptively simple. For example, the rear guards, C-pillars and roof are fabricated as one panel, which makes sense of the absence of shutlines around the rear of the car (except for the boot outline, of course).
Rolls-Royce refers to the Ghost’s cabin as an ‘interior suite’ consisting of no less than 338 individual panels. But despite that number, the feeling inside is simple and serene.
In fact, Rolls says its acoustic engineers are experts in serenity. Sounds like Darryl Kerrigan needs a Ghost for the family road trip to Bonnie Doon.
A few details stand out. The open pore wood trim is a welcome, tactile change from highly finished veneers that often do their best to look like plastic.
The proper metal chromed trim elements around the cabin confidently say quality and solidity, and the steering wheel, as well as the buttons around the multimedia controllers are subtle throwbacks.
The wheel has a circular central pad, with ancillary buttons around its lower perimeter, which echoes the style of the 1920s and ‘30s. You half expect an ignition advance/retard lever to sprout from its centre.
And the buttons around the media controllers use a combination of shape, colour and typeface to conjure up thoughts of the same era. They could be made of Bakelite.
For those that way inclined, the signature ‘Starlight Headliner’, using untold LEDS to create a glittering night sky in the roof, now incorporates a shooting star effect. You can even option up the constellation of your choice.
BMW 6 Series7/10
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.
The new Rolls-Royce Ghost is over 5.5m long, more than 2.1m wide, and close to 1.6m tall. And within that substantial footprint sits a 3295mm wheelbase, so no surprise utility and practicality are exceptional.
First, there’s getting in. The ‘coach’ or ‘clamshell’ doors will be familiar to current Ghost owners, but their “effortless” operation is new, a gentle pull on the door handle bringing welcome electronic assistance.
Once inside the rear of the car, as on the previous model, the press of a C-pillar-mounted button will close the door.
But up front, easing onto the generous driver’s seat is a breeze thanks to the Ghost’s sheer scale and a large door aperture.
There’s plenty of space for people and things in a thoroughly considered layout. A large glove box, big centre storage box (containing every connectivity option known to humankind) a lined slot for your phone and twin cupholders under a sliding timber cover. The door pockets are generous, with a sculpted section for bottles.
Then the rear. Obviously designed for two, the back seat will seat three. The sumptuous full-leather seats are multi-way electronically-adjustable, and NBA players (almost certainly prospective owners) will be happy with the leg, head and shoulder room provided.
Need even more room in the back? Step this way to the ‘Extended’ long-wheelbase version of the Ghost, measuring 5716mm long (+170mm), with a 3465mm wheelbase (+170mm), and stepping up in price to $740,000 (+$112,000). That’s $659 per additional millimetre, but who’s counting?
But back to the rear of the standard wheelbase car. Fold the large centre armrest down and twin cupholders pop out the front. Then, a wood-trimmed lid on the top flips forward to reveal a rotary multimedia controller.
Behind that, a beautifully trimmed storage box offers generous space and 12V power, and behind door number three (a pull-down leather panel in the back of the armrest aperture) is a small fridge. What else?
The rear of the front centre console houses individual climate-control outlets as well as USB and HDMI sockets.
Touch a discreet chrome button and small desks (RR calls them picnic tables) fold down from the front seat backs, faced in the same open pore wood as the dash, console, steering wheel, and door trims, and finished off with flawless chrome.
The entire interior benefits from a ‘Micro-Environment Purification System’ (MEPS), and rather than bore you with the details, let’s just say it’s exceptionally efficient.
Boot volume is a solid 500 litres, with an electrically-assisted lid and plush carpet lining. Of course, the air suspension system can lower the car to make loading heavy or awkward objects that little bit easier.
BMW 6 Series9/10
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.
Price and features
Good value is open to broad interpretation in this rarefied part of the new car market. On the surface, value could relate to standard equipment; the features that make life with a car safer, more comfortable, and efficient.
It might also have you lining up the competitors, to determine how much sheet metal, rubber and glass you’re getting for your money. Maybe a Mercedes-Maybach S-Class, or Bentley Flying Spur?
But peel away those layers and you’re getting closer to the heart of the Rolls-Royce value equation.
A Rolls-Royce is a statement of wealth, confirmation of status, and indicator of success. And that will be enough for some. But it also delivers value to those who appreciate the last few percentage points of creativity and effort that deliver exceptional results.
Sounds like a bit of a gush. But once you dip into the background of this car’s development and experience it first-hand, it’s hard not to.
We could produce a separate story on the Ghost’s standard features, but here’s the highlights reel. Included are: LED and laser headlights, 21-inch twin-spoke (part-polished) alloy wheels, electrically-adjustable, ventilated and massaging seats (front and rear), an 18-speaker audio system, electrically-assisted ‘Effortless Doors’, a head-up display, full leather trim (it’s everywhere), multiple digital screens, active cruise control, adaptive air suspension, and there’s lots more.
But let’s pick a few of those out for closer inspection. The audio system is designed and produced in house, featuring a 1300W amp and 18-channels (one for each RR built speaker).
In fact, there’s a team dedicated to audio performance, and it’s made the entire car an acoustic instrument, calibrating resonance through its structure to optimise clarity. Not the work of five minutes, requiring complex collaboration with the design and engineering teams, not to mention the bean counters.
And yes, there’s leather everywhere, but it’s of the highest quality, analysed to (literally) a granular level to ensure it makes the cut for use in this car. Even the stitching is set to a particular (longer than typical) length to minimise visual noise.
How about RR personnel travelling the globe to measure rain drops to make sure the roof rain channels perform as well as they can (true story). Or the 850 LED ‘stars’ in the dash fascia, backed by a 2.0mm thick ‘light guide’ with 90,000 laser-etched dots to disperse light evenly, yet add a twinkle.
You get the idea. And as much as they say, ‘If you have to ask the price, you can’t afford it’, the cost-of-entry for a 2021 Ghost, before any options or on-road costs, is $628,000.
Depending on your perspective, a stupendous sum that will by 42.7 entry-level Kia Picantos, a car every bit as capable of transporting you from A to B as the Ghost. Or alternately, brilliant value, in that it buys the ultimate attention to detail applied to this car’s design, development and execution. You be the judge, but for what it’s worth, I’m in the latter camp.
BMW 6 Series6/10
The BMW 6 Series Gran Turismo range starts off with the model tested here, the 630i. It has a list price of $123,500 before on-road costs - and that's whether you buy the M Sport Line or the Luxury Line.
That's quite a lot of money. And while it has a lot of equipment to help justify the cost, the smarter dollars will probably find their way to a more affordable 5 Series.
Standard gear in this spec includes adaptive air suspension with multiple drive modes, a colour head-up display, semi-autonomous parking, adaptive cruise control with steering assistance, auto high-beam LED headlights with LED daytime running lights, DAB+ digital radio, a 16-speaker harman/kardon sound system, a 12.3-inch driver information screen and a 10.25-inch media display with sat nav, Bluetooth and 'BMW ConnectedDrive' online services.
Hey, you even get a panoramic sunroof as standard! Plus there are things like an active rear spoiler, two USB ports and four 12-volt outlets, leather trim, heated front electric seats, electric steering wheel adjustment, keyless entry, push-button start, and an automatic boot.
It also comes loaded with active safety assistance functions - we'll get to that in the safety section below.
Things it's missing at this price point? Well, heated seats are an option, but bundled nicely into the 'Comfort Package' ($3000) which was fitted to our car. The pack includes heated seats front and rear, quad-zone climate control, electric sunblinds for the rear side windows, and electric seat back adjustment. Oh, and BMW continues to gouge consumers $623 for Apple CarPlay (which seemingly didn't work in our car).
The only other 6 Series GT model available is the 640i xDrive, which is again available with the choice of M Sport or Luxury body styling. It's also pretty exxy, with a list price of $148,900, but gets a more performance-focused drivetrain, as well as extra equipment: essentially the Comfort package, plus vented front seats, interior fragrance (eight options), memory settings for the front seats, 20-inch wheels and metallic paint.
Plus the 640i has Sport+ settings - it's probably the wrong car for those - and 'Integral Active Steering' to couple with the all-wheel drive system.
Engine & trans
The new Ghost is powered by an all-alloy, direct-injection, 6.75-litre, twin-turbo V12 (also used in the Cullinan SUV) producing 420kW (563hp) at 5000rpm, and 850Nm at 1600rpm.
The ‘six-and-three-quarter-litre’ V12 has a distant link to BMW’s ‘N74’ engine, but Rolls-Royce is at pains to point out this unit stands on its own two feet, and that every piece of it bears a RR part number.
It runs a Ghost-specific engine map, and permanently drives all four wheels through a GPS-guided eight-speed automatic transmission.
That’s right, the GPS link will pre-select the most appropriate gear for upcoming bends and terrain with the aim of producing “a sense of one endless gear.” More on that later.
BMW 6 Series8/10
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.
Rolls is currently quoting European Regulation (NEDC) fuel consumption numbers for the new Ghost, which for the combined (urban/extra-urban) cycle is 15.0L/100km, the big V12 emitting 343g/km of CO2 in the process.
On the launch drive, covering around 100km of urban pottering, B-road cornering, and freeway cruising, we saw a dash-indicated figure of 18.4L/100km.
Premium 95 RON unleaded fuel is recommended, but if circumstances (presumably in the back-of-beyond) demand it, standard 91 unleaded is usable.
Whichever you choose, you’ll need no less than 82 litres of it to fill the tank, at our average fuel use, enough for a theoretical range of 445km.
BMW 6 Series7/10
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.
So, if this Rolls is designed to be driven, what’s it like behind the wheel? Well for a start, it’s plush. As in, the front seats are big and comfortable, but surprisingly supportive and endlessly adjustable.
The digital instrument cluster tips its hat to classic RR dials, and despite thick pillars (especially the bulky B-pillars) vision all around is good.
And if you’re thinking 2553kg is a lot of Ghost to get moving, you’re right. But there’s nothing like applying 420kW/850Nm of twin-turbo V12 muscle to the task.
Peak torque is available from just 1600rpm (600rpm above idle) and Rolls-Royce claims 0-100km/h in 4.8sec. Plant the right foot and this car will calmly have you at throw-away-the-key speeds in the blink of an eye, the eight-speed auto shifting imperceptibly all the way. And even at full throttle, engine noise is relatively subtle.
But aside from that prodigious thrust, the next eye-opener is unbelievable ride quality. Rolls calls it ‘Magic Carpet Ride’, and it’s no exaggeration.
The bumpy road surface disappearing under the front wheels just doesn’t compute with the unruffled, perfectly smooth progress you’re experiencing. It is unbelievable.
I’ve only had that sensation once before, behind the wheel of a Bentley Mulsanne, but this was possibly even more surreal.
Rolls-Royce’s ‘Planar’ suspension system refers to, “a geometric plane which is completely flat and level”, and it works.
The set-up is double wishbones at the front (incorporating a unique to RR upper wishbone damper) and a five-link arrangement at the rear. But it’s the air suspension and active damping that create the magic Rolls calls “flight on land.”
A ‘Flagbearer’ stereo camera system in the windscreen reads the road ahead to proactively adjust the suspension up to 100km/h. It’s name recalls the early days of ‘motoring’ where a person waving a red flag walked in front of cars to warn unwary pedestrians. This slightly more sophisticated approach is just as arresting.
This time around the Ghost is all-wheel drive (rather than RWD) and it puts its power down brilliantly well. We dared to push it fairly aggressively on a twisting B-road section and all four fat Pirelli P Zero tyres (255/40 x 21) kept things on track without so much as a squeal.
A 50/50 weight distribution and the stiffness of the car’s aluminium space-frame architecture help keep it balanced, planted and under control. But on the flip side, steering feel is almost completely MIA. Numb and overly light, it’s the missing link in the Ghost’s otherwise impressive dynamic performance.
Drop into a freeway cruise and you become aware of the impossibly low noise level. But it’s not as quiet as it could be. Rolls says it’s able to achieve near silence, but adds that becomes disorienting, so it introduced an ambient “whisper”... “a single, subtle note.”
To achieve this level of calm the bulkhead and floor have been double-skinned, interior components are tuned to a specific resonance frequency, and there’s 100kg worth of acoustic damping materials within nearly half the architecture of the car, in the doors, roof, double-glazed windows, even inside the tyres.
The four-wheel steering system helps with agility on the highway (where the front and rear axles steer in unison), but comes into its own at parking speeds (where they counter-steer), because even with numerous cameras and sensors, parking this 5.5m long, 2.5-tonne machine is quite an undertaking. Turning circle is still 13.0m, though, so beware. If all else fails, the car will park itself, anyway.
Beefy ventilated disc brakes front and rear wash off speed progressively and without a hint of drama.
Other highlights? The multimedia system is the only thing openly borrowed from BMW, but that’s not a problem because the interface is great. And that 1300W, 18-speaker 18-channel audio system absolutely cranks!
BMW 6 Series7/10
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.
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.
Rolls-Royce doesn’t submit its cars for independent safety assessment, so no ANCAP rating for the new Ghost, unless, of course, the local testing authority chooses to purchase one. Enough said...
The previous Ghost was limited by its ageing 7 Series platform when it came to the latest active safety tech, But this version, sitting on a bespoke RR chassis, brings the entry-point Roller up to speed.
Included are AEB, incorporating ‘Vision Assist’ (day and night wildlife and pedestrian detection), active cruise control (with semi-autonomous driving mode), cross-traffic warning, lane-departure and lane-change warning, as well as an ‘Alertness Assistant.’
There’s also a four-camera system with panoramic and helicopter view, as well as a self-park function, and a hi-res head-up display
If all that’s not enough to avoid an impact, passive safety includes eight airbags (front, front side, full-length curtain, and front knee).
There are also top tethers and ISOFIX anchors on the two outer rear seat positions for safely securing child restraints for kids fortunate enough to be travelling in this kind of style.
BMW 6 Series9/10
The BMW 6 Series GT range has a five-star Euro NCAP crash test score based on 2017 testing, but it hasn't been scored by ANCAP.
There's the usual array of airbags - dual front, front side, full-length curtain and driver's knee airbags are included, plus parking sensors all around, and heaps of safety tech including the 'Driving Assistant Plus' package with lane departure warning and lane keeping assist, forward collision warning, auto emergency braking (AEB) front and rear, blind-spot monitoring and rear cross-traffic alert, and adaptive cruise control with stop and go.
That's all great stuff, and so is the 360-degree camera system with adaptive display - so, if you're reversing and you turn the wheel to one side, the image on screen will move, too. It'll also go between a birds-eye view and a backing-up perspective, and that can take some getting used to.
What was less convincing in terms of the user experience was the rear auto braking, which seemed to be scared of the car's own shadow. On multiple occasions the car jammed on the brakes when reversing out of driveways on to empty streets - be it in the normal height, or the raised height setting.
The 6 Series GT has dual ISOFIX anchor points and three top-tether points are there and ready for baby seats or child seats.
Rolls-Royce covers its Australian range with a four year/unlimited km warranty, but that's just the tip of the ownership iceberg.
The mysterious ‘Whispers’ owners portal, a “world beyond”, is claimed to offer the opportunity, “to gain access to the inaccessible, to discover rare finds, to connect with like-minds.”
Plug your car’s VIN into the app and you’ll be on the receiving end of curated content, event invitations, news and offers, as well as access to your own ‘Rolls-Royce garage’, plus a 24/7 concierge. All complimentary.
What’s more, service is recommended every 12 months/15,000km, and it’s free-of-charge for the duration of the warranty.
BMW 6 Series8/10
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.
