BMW M Models vs Rolls-Royce Ghost

What's the difference?

Brutal, bruising and utterly brilliant, the M4 CS will be an acquired taste due to its no-compromise approach, but those willing to take the leap will find a performance car like few others at their disposal.

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. 

The M4 CS is familiar in all the right ways, but definitely looks significantly jacked up compared to its lesser siblings.

Part of that is the extensive use of carbon everywhere, from its bonnet panels to its roof, front lip, side skirting and boot spoiler. But also because of its super-muscular angles and creases, including the huge dome in its bonnet.

Also exclusive to this M4 CS is the light treatment, with the front LEDs lighting up with yellow highlights the brand says are supposed to be reminiscent of GT racing cars.

At the back, the rear lights are flush with fibre optic lighting, lending a flowing and unique light signature that looks epic at night.

Inside, it's a sea of carbon, with the lightweight racing seats, the dash inserts and the centre console all lined in it. It is a perfectly finished space, though, and one that's also flecked with red, including a 12 o'clock band on the thick-rimmed steering wheel, the seat backs, the contrast stitching and the paddle shifts.

Be warned, though, it takes some acrobatics to climb into or out of the CS. The seat bottoms have these super high edges that double as grab handles, but require some awkward contortions to navigate.

In short, it looks angry, this M4 CS, inside and out.

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.

It all boils down to how you classify practicality in a car like this. I mean, the basic stuff is all there – it's got two doors, four seats and a boot capacity of 440 litres.

It measures 4801mm in length, 1918mm in width and 1399mm in height, and room for front seat riders is good, but less so for anyone you squeeze into the back. There are even ISOFIX points for a child seat.

But if you consider practicality the practical pursuit of performance, then the M4 CS has plenty of perks.

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.

BMW has found yet more grunt lurking in its trusty 3.0-litre 'M TwinPower' six-cylinder petrol engine, with the M4 CS now pumping out 405kW and 650Nm.

That's a decent jump from the 390kW and 620Nm served up by the M4 Competition, and a giant leap from the outputs of the 'base' M4 – 353kW and 550Nm.

Predictably, then, the CS is the fastest of the lot, knocking off the run from 0-100km/h in 3.4 seconds, compared to 3.5 and 4.2 in the Competition and M4, respectively. The top speed is also dialled up to 302km/h.

All that power is channeled through an eight-speed automatic and sent to all four wheels on demand, with the help of an 'Active M Differential'.

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.

The M4 CS is fitted with a 59-litre fuel tank, which – given the BMW's official fuel claim of 10.2 litres per hundred kilometres – should deliver a driving range on a full tank of 541 kilometres.

But... BMW also says the regular M4 – you know, the one that makes 52 fewer kilowatts and 55Nm less torque – uses 10.1L/100km, so do with that information what you will.

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.

The hardest and angriest M4 of all time is, perhaps unsurprisingly, hard and angry. This is a race track specialist, but because I don't happen to own one of those, my first experience with the barking (and barking mad) M4 CS was navigating my way back from BMW's inner-city dealership.

Like it or lump it, you're going to read some Porsche comparisons here, because you're talking not too far off base 911 Carrera money, and suddenly I find the two Germans doing battle for a spot in my dream garage.

First things first, the BMW won't be much chop for daily driving for most people. Happily, I have a sickness for uncomfortable sports cars. It tells me that no compromises have been made in the pursuit of punishing performance.

A good thing, too, because the BMW, at city speeds, can be punishing. Everything feels heavy, the seats aren't overly comfortable – especially the hard bits that tend to dig in when cornering – and it stiff-arms its way over road imperfections, that exhaust booming and barking as it does.

Again, I loved it, and you probably will, too. But it's still not the kind of car I'd relish sitting in the morning peak hour rush in.

But escape the confines of the city and the BMW M4 CS suddenly makes a whole heap of sense. The acceleration is genuinely brutal, and wonderfully theatrical, with that quad-tipped titanium exhaust barking and snarling as you rocket towards 100km/h.

The steering is brilliant, with feedback fed to your wrists via that thick-rimmed wheel, and the entire experience feels sharp, super engaging and edgy.

You can push the M4 hard and fast, and I'm certain my limited talents would run out far before the BMW's would, but there's this thrilling sense of peril sparked by the aggression of the experience, that I love.

It's like the magic of a roller-coaster, I guess. Even if you know nothing is going to happen, you never really know, right? And in that lies the magic.

But back to original question, this or a Porsche 911? There's no doubt a Carrera is a better all-rounder, in terms of comfy commuting and race track fun, but this angry M4 is all shouty theatrics, all of the time.

I bloody love it.

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.

The M4 CS is covered by BMW's five-year, unlimited-kilometre warranty, with condition-based servicing available in packs, which will cost you $3530 over five years/80,000km, or $2900 over four years/60,000km.

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.
