Rolls-Royce Ghost vs BMW Alpina B7

What's the difference?

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. 

The BMW Alpina B7 is a special car destined (like all Alpinas) to be a collector's item, due to its rarity and exclusivity. I asked Alpina just how many current model B7s there are in Australia and the answer was "less than five", which is just as mysterious as most people find the car in general.

The B7 is fast – too fast to enjoy legally on Australian roads – but it is also supremely comfortable and well appointed. For Alpina fans lucky enough to be driven in on,e this would make for a truly rare and niche way to be chauffeured.

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.

This is a good place to start because the B7 looks just like the 750Li it's based on, until you see the first tell-tale signs that it's not one.

There's the front wing with Alpina lettering and the boot-top spoiler, the graphics, which run the length of the car, and the 20-spoke wheels with Alpina badging.

This is late '70s, early '80s styling at its best (and possibly worst), but these special cars can pull off the irony-free look because this is how Alpina BMWs have rolled since 1975, when the E21 320-based Alpina A1/3 was launched.

BMW badges have been left on the bonnet and boot, but there's Alpina B7 BiTurbo lettering in place of the 7 Series identifier.

Most people walked by it in the street thinking it was just a big BMW, others scratched their heads wondering what I'd done to my big German limo and a handful almost dropped to their knees in praise and wonderment at spotting a rare beast like this in the wild.

These people all had their own Alpina stories – one was the third generation of an Alpina-owning family. You become a member a small and passionate club when you buy into this rarefied brand.

The standard B7's cabin is close to identical to the luxurious interior of the 750Li, save for Alpina-embossed stitching in the headrests of the soft, leather seats, the virtual instrument cluster and the Alpina plaque on the centre console denoting the build number.

The B7 is long, low and wide at just under 5.3m end to end, 1.5m tall and 1.9m across. A 3.2m wheelbase means cabin room is more than just spacious.

The B7 rolls off the Dingolfing production line in Germany and is then handed over to Alpina's facility in Buckle, where significant changes take place. Read on to find out how the B7 is different from a regular 750Li.

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.

The B7 is a five-seater limousine although with the fold-down rear centre armrest which houses the media control panel the back is really set up to carry two.

That 3.2m wheelbase means cabin space is enormous. At 191cm tall I can sit behind my driving position with about 30cm between my knees and the seatback. Those rear doors open wide and the entrance is huge, making entry and exit almost as easy as just walking through a doorway. The air suspension also rises and lowers the B7's ride height for better access.

Storage is excellent, with two cupholders and door pockets for rear passengers, along with the area inside the centre armrest.

Up front, the driver and co-pilot have a deep centre console storage bin with split-opening lid, two cupholders and door pockets.

Luggage space is good, with a 515-litre boot.

The B7 lists for $389,955, while a 750li is about $319,000. At this level, $70K seems like a downright reasonable premium to pay for a faster, more powerful, better handling and comfier version of the 750Li.

In this case you're paying more but getting more, although standard features are close to identical. There's adaptive LED headlights, head-up display, night vision with pedestrian detection, a 10.25-inch touch screen up front and two screens in the second row for TV and other media functions.

There's a reversing camera, sat nav, harman/kardon surround stereo and Apple CarPlay. There's leather upholstery, seat massagers in the front and rear, four-zone climate control, heated and ventilated front and rear seats, front and rear parking sensors, auto tailgate, sunblinds for the rear and rear-side windows and proximity key.

The safety features are listed in the section below, and that list is also impressive.

Rivals to the B7 include the Mercedes-AMG S63, which lists for $375,000, the $331,700 Audi S8 and even the Bentley Flying Spur, which almost matches its price at $389,500.

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.

Alpina takes the 4.4-litre twin turbo V8 from the BMW 750Li and rebuilds the engine by hand. Alpina fits its own turbochargers, air-intake set -up, high-capacity cooling system and Akrapovic quad exhaust. Output is 447kW and 800Nm – an increase of a whopping 117kW and 150Nm over the 750Li's grunt.

It's interesting to note that the V12-powered 760Li has a smidge more power, at 448kW, and the same torque output as the B7.

How fast is the B7? Supercar fast – the B7 has a top speed of 330km/h, which will see it outrun a McLaren 570 and almost keep up with a Ferrari F12. That's quite incredible for a 2.3-tonne limousine with three TVs on board. A 0-100km/h time of 4.2 seconds is also hugely impressive.

In comparison, a 750Li has a 0-100km/h time of a not-too-shabby 4.7 seconds, but the car is electronically limited to 250km/h.

An eight-speed automatic transmission shifts gears smoothly, although a little slowly in Normal mode, while Sport and Sport+ add urgency and harder shifts.

Finally, the B7 is all-wheel drive, and those rear wheels are designed to steer slightly for better cornering performance.

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.

The B7 is probably not the car to own if you're concerned about either fuel prices or emissions, but then the twin-turbo V8 may not be as thirsty as you'd think, with Alpina stating that, after a combination of urban and open-road driving, you should only use 9.6L/100km.

My time in the B7 saw me double that usage but this could have had something to do with me turning off the stop-start system and driving in Sport mode constantly.

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!

Who on Earth thinks a BMW 750Li isn't fast enough or comfortable enough, even with all its horsepower, luxurious cabin and technology? Alpina, that's who.

Redevelopment of the 4.4-litre V8 with new turbochargers, a high-capacity cooling system, different air suspension set-up and an exhaust system made by Akrapovic have made this already exceptional car better. Better to drive and better to be driven in.

The ride, even on those 21-inch wheels and low-profile Michelin Pilot Super Sport tyres (255/35 ZR21 on the front and 295/30 ZR 21 on the rear) is incredibly comfortable. I drove it and also had a chance to recline in the back and be chauffeured (by our photographer) and the ride was so composed and refined it was hard to believe I was travelling along some truly awful urban roads with their cracked and pot-holed surfaces.

And it's quiet, too. Which will suit those in the back being transported swiftly from the airport to their next meeting, but if you're after a loud and angry exhaust note then you won't find it in the B7. Sure, from the outside at full throttle the B7 has a menacing growl, but this isn't a BMW M car that will bark and snarl. 
See, while BMW's M division makes brutal, loud, high-performance versions of their regular cars, Alpina makes comfortable, stealthy, high-performance ones.

All-wheel drive provides fantastic traction and ensures that grunt doesn't just tear the tyres off those rims when you sneeze on the throttle.

And while the air-suspension is soft and comfortable, adaptive dampers adjust for when the road goes twisty, providing impressive handling for a heavy and long car.

Really, though, the B7 is built for long, endless stretches of roads, and the acceleration beyond 100km/h is almost as startling as that from 0-100km/h, as it wants to push straight past 200km/h towards that 330km/h top speed.

Which, unless you know a good lawyer or happen to be one, will send you straight to jail. Yes, the B7 is probably too much car for Australian roads. Only on a German autobahn would a B7 be fully at home.

I felt like I was given a Melbourne Cup-winning racehorse for a week but could only ride it in my suburban backyard.

The Alpina B7 comes with all of the BMW 750Li's safety equipment – this includes AEB, lane-keeping assistance and lane-departure warning, blind-spot warning, active cruise control, night vision with object recognition, auto parking and surround view camera.

Along with the suite of airbags, there's traction and stability control and ABS, as you'd expect.

The 750Li and B7 have not been given an ANCAP score.

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.

The B7 is covered by BMW's three-year, unlimited-kilometre warranty. Servicing is recommended every 12 months or 15,000km. The B7 is covered by BMW special vehicles servicing plan, which means services are cost-free for the first three years of the car's life.
