BMW 840I vs Rolls-Royce Ghost

What's the difference?

If you’re the sort of buyer who wants a car that signifies a lifestyle that is ‘large and in charge’, the BMW M850i Gran Coupe could be just the thing for you. It isn’t as showy as some of its competitors, and mightn’t reach the same levels of excitement as those cars either - but it is a convincing offering in its own right, and a beautiful piece of design at that. 

In a disruptive era when the coachbuilder has pivoted to SUVs like the Cullinan, a sort of London black cab that’s been dipped in opulence, and succeeds despite itself, and the brand’s grand, million-dollar EV, the Spectre, the Ghost is a safe and familiar space. 

A beautiful, long, broad, immaculate land boat. It’s a space Rolls inhabits with relish. 

The Ghost Series II feels nothing like a track-day option when you’re behind the wheel. But it might do if you were stepping out of a Phantom. Or a Cullinan. Or a Wraith. Especially if you’re stepping out of the back doors. 

It’s the perfect driver’s car. As long as all your other cars are also Rolls-Royces. 

This could be BMW’s most convincing design in years. I mean, the X5 is predictably handsome, the X3 was unexpectedly muscled, and the less said about the frumpy 1 Series and busy 3 Series (apart from the wagon… drool) the better.

To my untrained but enthusiastic eye, the 8 Series Coupe is a bit too rounded over its rear haunches, and the rear screen is just a little steep - to me, that lets its dimensions down a little. But this. This is gorgeous. 

I mean, you might have questions over the tail-light design, which is a theme across a few BMW models now. But there isn’t as much confrontation between horizontal and vertical graphics for this model as you’ll find one other big Bimmers, like the X7. 

The M850i model has BMW Laserlight headlights, which throw a sharp beam and look menacing in their signature, while the grille and bumper are strong. The stance of the car is prominent - there’s a long body, a long wheelbase, and a long body in general. The standard wheel package consists of 20-inch rims, and they don’t look disarmingly large.

As our images show, there’s a lot to talk about when it comes interior design and finishes, but the cabin doesn’t quite benefit quite as mochas you might think it would from all that real estate. I mean, with dimensions of 5074mm long (on a 3023mm wheelbase), 1932mm wide and 1402mm tall, this is a squat, yet substantial vehicle. It’s just more cramped than you’d think inside.

Yes, its exterior is more monolithic than before. The previous iteration was hardly fiddly, but the (apparently client driven) evolution here edges ever so gracefully towards what Rolls-Royce might secretly think of as brutalism.

The Ghost Series II’s generous 2148mm width is further emphasised up front, stretched across its upright prow, with slimline headlights adding definition and — surprisingly — a touch of villainy.

New, Spectre-inspired tail lamps and a discreetly inscribed double ‘R’ monogram add a reserved flourish from behind, and buyers can choose from two new 22-inch, nine-spoke wheel designs.

It’s subtle, no doubt. But it’s also impeccable.

I recall a Mitsubishi designer telling me, once upon a time, that he dreamed of making ‘a big car on the outside with a very small interior’. Maybe he made the jump to BMW, because that’s pretty much the 8 Series Gran Coupe.

There aren’t many other vehicles on the market, of this size, that offer less space inside. The boot capacity, for instance, is just 440 litres. Competitors like the Audi A7 (535L) and Mercedes CLS (520L) easily outdo it - but at least this car has more boot than the Panamera (405L), though the BMW is a smidge bigger. The cargo space is large enough for a couple of overnight suitcases, but you’re hardly going to fit a family of four’s luggage for a week away. 

And while we’re in the “not quite what you’d expect” column, the back seat space is hardly commodious. There’s enough space for me, at 182cm, to sit behind my own driving position, but not without wishing for a bit more toeroom, headroom and knee space. 

The big centre console section eats into the space in the rear, justifying the brand’s “4+1” seating claim, and unpleasantly it has a hard plastic finish to rest your leg against. Getting in and out of the second row isn’t easy for bigger people, and it’s quite a squat down into the rear seat - it really has taken inspiration from its squashy-back-seated predecessor in that regard.

If you have smaller rear-seat occupants, however, there will be catered for with dual ISOFIX and three top-tether points, plus there are air vents with climate controls (quad zone in total), and two USB-C ports as well. There are sun-blinds on the rear windows, too, which is a plus, and there is a pair of cup holders in the fold-down armrest, and map pockets in the seat backs, too. The door pockets are near-useless, though.

The front seats score better practicality, with bottle holders in the doors, bigger and sturdier cup holders, a covered centre storage bin between the seats with a USB-C port, and a wireless phone charger (Qi) with standard USB port in front of the gear selector.

Above that is the weird, very out-of-place quick buttons (1-8) that BMW could easily do away with, and further up are the controls for the climate control (thankfully with hard buttons for fan speed and temperature), and above that is the media screen, a familiar looking 10.25-inch touch display running BMW OS 7.0. 

The screen is quick and crisp, and is backed up by the rotary controller and buttons on in the centre console area. There’s wireless Apple CarPlay (now at no cost for three years), as well as a built-in SIM card for 4G data and access to the BMW Online news and weather stations, accessed through the screen.  

It’s all pretty easy to use, and the sound system is excellent - the standard setup consists of 16 speakers, with DAB+ digital radio, Bluetooth and USB plus the smartphone mirroring tech, provided you don’t have an Android device, as Android Auto is still missing from BMW’s range.

It’s a nice cabin, but I couldn’t help but thinking that I’d want a little more differentiation from the lesser models in the range if I was spending this much. Especially considering the optional cost of the interior trim fitted to our test car - see below for more detail.

Inside, yes, there are bonkers touches in this most refined of automotive spaces, such as upholstery pinpricked by 107,000 'Placed Perforations' of 1.2mm in diameter, each individually examined, that replicate the shape of some clouds spotted over Rolls-Royce's Goodwood HQ. 

Beside those flourishes of lunatic opulence, the more practical features feel pedestrian, but they’re comprehensive. The wireless Apple CarPlay and Android Auto, the seamless 'Central Information Display' and the 18-speaker 1400-watt audio, the upgraded Wi-Fi hotspot and the unobtrusive USB-C ports. The rear-seats flush with giant, streaming-optimised screens and heated and ventilated massaging seats.

Rolls acknowledges the generational movement of its clientele from back seat to front, with over 90 per cent of buyers now opting to — gasp! — steer themselves in a Ghost. But with back-seat savoir faire in its DNA, Rolls simply extends its hospitality to every seat.

The Ghost Series II is yours for an indicative price of just $680,000 (or $800K for the Black Badge) plus substantial on-road costs. The Ghost Series II extended (which we didn’t drive at the international launch in Provence) will slip in at around $20K less than the Black Badge before additional charges. 

If they seem like big numbers, you’re probably the sort of person who looks at price tags, or who shops in shops that put price tags on things. These are not common traits of Rolls-Royce buyers, who may only be vaguely aware of the actual price of their vehicle, and whose historical impression of guillotines is generally unfavourable.

So, high six-hundreds is table stakes.

But you might also think the ‘standard’ Ghost, like all Rolls-Royces, is considered by most buyers to be a mere starting point, from which they’ll typically up-spec their ride from a sumptuous and expensive options list.

Spending another 10 percent of the purchase price on customisation is a bare-bones outlay for most owners, but even so, the evolved Ghost’s out-of-the-box features are so comprehensive as to be almost overwhelming. 

First, because the Ghost has been Rolls-Royce’s driver’s car since the first (modern) generation arrived in 2010, specifically to cater to a weird (for Rolls clientele) new generation of buyers who wanted to drive their Rolls themselves. 

So that price gets you, above all, that proven but superb 6.75-litre twin-turbo V12 engine, massaged via an eight-speed transmission and an AWD system that’s as rich and viscous as Crassus’s last libation.

There’s its subtly tinkered 'flight on land' 'Planar Suspension System' (note the unspoken dissonance between the terms ‘flight on land’ and ‘driver-focused'), with an ingenious 'Satellite Aided Transmission' system that uses GPS to pick the ideal gear with which to launch out of turns.

It works hand-in-velvet-glove with Goodwood's 'Flagbearer' camera system, which tracks the road ahead to chide potholes into submission in advance.

Because it’s a Rolls, though, that’s barely even the start of the story. 

The coachwork is extraordinary, with new trim options including natural open-pore 'Grey Stained Ash' design elements, a sumptuous new bamboo rayon textile called 'Duality Twill'.

There a night-sky inspired illuminated fascia that apes elements of time-lapse celestial photography, part of the central glass panel that stretches the length of the dash. 

Sure, you might expect that level of detail for the outlay. But for the outlay it’s far from missing anything you’d expect.

If you’re going for the M850i, you’re getting the big bopper engine. It’s a 4.4-litre twin-turbo V8 petrol engine, and it isn’t short on horsepower.

The outputs for this engine are 390kW of power (at 6000rpm) and 750Nm of torque (from 1800-4600rpm). Hardly numbers to sneeze at.

And the performance figures are exceptional, too: the claimed 0-100 km/h time is just 3.9 seconds. That’s because there’s the traction of BMW’s xDrive all-wheel drive system, and shifting gears is an eight-speed automatic transmission.  

For what it’s worth, your humble reviewer saw a 0-100km/h time very close to that (4.2sec). 

The quoted kerb weight for this model is 1995kg.

Rolls doesn’t like acceleration figures — too gauche, darling — but armed with that proven 420kW and 850Nm V12, the Ghost Series II has serious heft. Delivering max torque from 1600rpm — just 600rpm above idle — the effect is genuinely of one endless surge, a wafting cloud of momentum that subtly slips between gears as it exudes itself across the countryside.

The Black Badge edition, like all of its, er, ‘disruptive’ ilk offers a ‘Low’ button (‘Low’ means ‘Sport’ in Rollspeak), which bumps gearshift speeds by 50 percent when you plant your foot, and delivers a distinctly non-Rolls-like pop and burble on overrun. It also provides an extra 21kW and 50Nm, because Black Badge is mean and tough.

You can’t really expect a big V8 beast like this to be a fuel miser, and it isn’t.

The claimed consumption is 10.7 litres per 100 kilometres. Which is alright, honestly, given the sheer volume of car you’re driving. 

But on my test - which consisted of more than 300km of mixed driving, including days of city commuting, some twisty mountain driving, and all the freeway floundering to get there - I saw an at the pump real-world figure of 15.4L/100km.

That’s not very efficient, and it’ll be expensive to run on the daily — yet the argument could be made that if you’re spending this much on a car, fuel costs won’t matter much to you. But with a small fuel tank capacity of 68 litres, it could become a little inconvenient as you’ll be seeing a lot of your local servo.

Provence is not entirely a driver’s paradise, with every stretch of slightly twisty tarmac only a counterpoint to a motorway lined with Marseille lorries, Depardieu-esque men in tractors who refuse to move to the verge, and small villages where each kerbside corners sit millimetres from the foot of an adjacent boulangerie.

Which is to say it’s neither a place for economy runs, nor a location at which to run up the consumption numbers with a madcap series of impromptu hill climbs.

Our Ghost II drive returned around 16L/100km, which feels about right with that gorilla-in-a-tuxedo 6.75L V12, and is only slightly above the official figures of 15.8L/100km. Not great, could be worse.

It’s an impressive thing, this M850i xDrive Gran Coupe. But I’m just not sure who it’s trying to please.

It’s not the sort of German monster coupe-sedan that grabs you by the scruff of the neck and throws you around with its mammoth acceleration. Not unless you poke it and prod it and make it really angry.

And that might be exactly what you want to do - put it in Sport mode, sling the shifter across to sport or manual mode, hear the exhaust open up from a pursed-lip tongue-click to an open-mouth growl. 

You’ll push hard on the accelerator, watch the tacho needle jolt to the redline, and if you’re in auto mode you’ll feel the transmission whipcrack as it shifts rapidly up through the gears as you’re shoved back into your seat. Before you know it you’ll be in licence-loss zone, and you won’t have even made the tyres chirp - that’s how immense the traction from the all-wheel drive system is.

You’ll brake hard into a sharp bend, and you’ll feel the front end dip and the body of the car change direction more readily than you’d think given its size as you turn in. The steering response will meet your expectation, with rapid reaction to adjustments mid corner. And the Active Roll stabilisation system will mean you’re not being thrown around in your seat, because it’s sitting flatter and truer than you might have expected - you’ll notice how it works extremely well in conjunction with the car’s torque-vectoring-by-braking system. There’ll be little weight shift or body roll to be counteracted, and that’ll inspire you to push it even harder.

Put it in manual transmission mode and you’ll rejoice that it won’t overrule you and shift up, but you’ll also feel shortchanged because it gets to the end of its limit very quickly. And when it hits redline, it emits a breathless little cough rather than a “oh maybe I should stop” rev-bounce noise.

But, if you’re like me, you might be doing all this with a niggling thought in the back of your mind that, while this car is technically really good and it’s a clinical performance car, you might just think to yourself, “I’m not having as much fun as I thought I would”.

A Mercedes-AMG would be more fun; it’d be more raucous, more of a muscle car experience. An Audi RS7 (at least the previous one) would be noisier, brasher, more theatrical than this car. And likewise, a Porsche Panamera - no matter the model you go for - would be more entertaining in the bends.  

Maybe it’s just a bit too predictable - and maybe that’s a result of this car being honed for drivers who will spend more time on the Autobahn than anywhere else. I have to say, there are much, much worse (and slower) ways of getting from A to B, and the highway cruising comfort of the M850i Gran Coupe was what impressed me most. 

It’s also surprisingly adept at urban driving duties, coping well with unpleasant city surfaces, though potholes can still upset things because of the stiff-sidewalled run-flat tyres. The suspension does an exceptional job otherwise, however, and I switched between the Adaptive drive mode and Comfort mode for my commuting duties. Both proved comfortable and controlled.

The M850i is by no means a failure when it comes to fulfilling the expectations you might have of a luxury sports sedan of this size. In fact, it’s close to a distinction. But I just can’t help thinking that it’s not as much an ‘M car’ as that M850i badge might have you believe it should be.

The Ghost Series II drives like a magic carpet, serene and untroubled; in almost any stable other than that of Rolls, calling it a ‘driver’s car’ would have you throttled by their skunkworks. Everything is relative.

Still, it hides its considerable dimensions well. There’s never any doubt that you’re in a large saloon, as you white-knuckle the Ghost’s impeccably appointed steering wheel, but there’s always enough power to deliver creamily instant throttle response, even in the case of initially misjudged cambers. 

Nor can the Black Badge hide the shimmy of that characteristic ‘flight on land’ body drift. The upside is that its manners are impeccable, even through the worst possible pieces of corrugation Provence can deliver. 

If anything, the Ghost Series II’s big-hearted bulk adds to the fun factor, especially in some of Rolls-Royce’s more garish colour options, when gasping South of France MAMILs stare in amazement as a bright yellow, five-and-a-half metre Rolls passes them on the outside, scattering their various baguettes and garlands of onions.

You get airbags, ESC, adaptive cruise, parking sensors and auto parking, and a rear camera. But don’t expect Rolls-Royce to allow the blighters at ANCAP to wreck one.

BMW backs its cars in Australia with a three-year/unlimited kilometre warranty.

You may be confused if you head to the BMW site and see that M models and 8 Series models aren’t covered by BMW’s pre-pay capped price servicing plan (as I saw when testing this car), but CarsGuide can confirm that the 8 Series is indeed covered - unless it’s the real M8, not this M850i jigger. 

BMW Australia has clarified that the Service Inclusive pack for five years/80,000km of maintenance cover is $2490 for Basic cover (no brakes/pads, no wiper replacement), or $5641 for the more comprehensive Plus pack. Hardly affordable, but nor’s the car. 

The company uses a condition-based servicing program, too - there are no set service intervals, but the car will tell you when it needs maintenance based on how you drive it.

For what it’s worth, we ran the numbers on resale value using Glass’s Guide predictive analysis tool, and after three years/40,000km the expected retained value for this version is approximately 66 per cent - which is impressive.

Expect just a four-year servicing and warranty offer for Australian customers of this vehicle. So that means an unlimited-mileage warranty, including all services, for the first four years.
