Rolls-Royce Ghost vs BMW Alpina B5

What's the difference?

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 Alpina B5 is a special car – more special than most people will ever give you credit for if you own one. Those that do know what an Alpina is will let you know; people will cross dangerously busy streets to talk to you about your car. Insanely fast, almost incomprehensibly comfortable and effortlessly powerful to drive.

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.

Interesting is the right word for it, because while it might be questionable that Alpina's changes to the exterior are aesthetic pleasing, they are definitely intriguing to those who aren't familiar with the brand.

First, there are those 20-spoke wheels. Alpinas have worn this style of wheel forever and they've become the most famous outward sign that this is not just another BMW. So don't under any circumstances take them off and replace them with anything else. You'd be run out of town by the Alpina mafia.

Yes, they're more painful to clean than a cheese grater (trust me, I know. And if you look closely at these images you can see the dirty bits I've missed), but if you really don't like them then perhaps it's a sign this car isn't for you.

Then there's the boot-lid spoiler. It's square and 1980s'-looking, it also appears a bit like it's been bought online and installed by a teenager, but again, this is another Alpina tradition and it suits the car's character perfectly.

All right, those pinstripes; they're known as the Deco-Set and are a hat-tip to the Alpina racecars of the 1970s and '80s. Again, don't take these off, your Alpina will drop through the centre of the Earth in value. These are also part-and-parcel of owning one of these cars. I'm not a massive fan of them.

But I'm all about that front spoiler, with the floating Alpina lettering that you can option in silver, high-gloss black or gold.

Inside, there are fewer Alpina additions, but they're nonetheless unmissable. There's the Alpina-badged steering wheel, and a new virtual instrument cluster, embossed headrests and  illuminated door sills.

There's also the little numbered plaque on the centre console which proves its authenticity, ours was number 49. Out of how many? I don't know. But I do know Alpina produces only about 1700 cars globally a year. Rolls Royce does about 4000. So, you can rest assured your B5 is exclusive.

At almost 5m long, 1.9m wide and 1.5m tall, the B5 is a large saloon, but having recently reviewed the Alpina B7 it feels small in comparison. How does it drive? We're getting there.

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.

Practicality is not really a BMW strong point no matter which model you pick. See, BMW mostly makes the car equivalent of uber-stylish and skin-tight active wear which looks good and performs brilliantly, but sometimes you just want pockets and a bit of room for your… um… bits and pieces.

So while there are two cup holders up front and two in the back, the bottle holders in the doors aren't huge, the centre console bin is on the small side, there's a hidy-hole in front of the shifter, the glove box is just a box for little more than gloves and there's no other great cabin storage options.

Legroom in the rear is good but not great, too - I'm 191cm tall and have about 30mm between my knees and the seat back in my driving position. Middle-seat passengers will also have to straddle the drive shaft hump in the floor. Headroom is restricted in the back, too (you could blame the sunroof) with my hair just skimming the headlining (I do have big hair).

Under that power tailgate, the B5's boot capacity is 530 litres which is 15L more than its big sister, the B7. There are two plastic storage areas either side of the luggage space for wet things. While there is one USB outlet in the front there aren't any in the rear.

The BMW Alpina B5 lists for $210,000, making it only $10K more the BMW M5 which comes with almost identical features apart from the Alpina engineering to the engine and chassis.

Arriving standard is leather upholstery, four-zone climate control, nav, the Alpina embossed-headrests, a 10.25-inch display, digital radio, Alpina door sills, sunroof, proximity key, power front seats, 12-speaker Harman Kardon stereo, head-up display, Alpina virtual instrument cluster, heated front and rear seats, and the 20-inch Alpina wheels.

The test car I drove had been optioned with a limited-slip differential ($5923), steering-wheel heating ($449); soft-close function for doors ($1150); sunblinds ($1059); TV function ($2065) ambient air package ($575), and front-seat ventilation ($1454).

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 Alpina B5 uses the same 4.4-litre V8 engine found in the BMW M5 (and also the B7). But, and it's a big but, the M5 makes 441kW and 750Nm, while the B5 outdoes it with 447kW and 800Nm. Admittedly, the B5's torque arrives at the 3000rpm mark, while the M5's is all there from 1800rpm.

How does the B5 beat it? Alpina installed its specially developed twin turbochargers and intercoolers, a high-performance cooling system, a reconfigured air intake set up and a different exhaust system.

The B5, though, is a tenth of a second slower to 100km/h compared to the M5 with a time of 3.5 seconds, but it will blast on to a top speed of 330km/h while the M5 is limited to 250km/h in regular form and 305km/h with the optional M Driver's package.

Both uses the same ZF eight-speed automatic transmission with identical gear ratios, and both are all-wheel drive.

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 Alpina B5 needs petrol. By that, I mean it needs quite a lot of it if you want to enjoy it properly. What type of mileage does it get? Officially, it should use 11.1L/100km after a combination of urban and open roads, where as the M5 is set to 10.5L/100km.

That makes sense, the B5 produces more power and torque, and it's 85kg heavier than the M5 at 2015kg.

Our test car's trip computer was reporting 13.2L/100km after flying low over country roads and slow city piloting. The more time spent in the urban warfare that is the daily peak hour commute, the more that figure crept and hovered around the 15L/100km mark.

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.

Ok, stay with me here. For this next bit you'll need a fresh egg, a lounge chair, and it might be a good idea to have some plastic bags and carpet cleaner on hand.

First, in front of the lounge chair flatten out the plastic bag and place the egg on it. Next, sit down on the chair and very carefully rest the ball of your foot on the egg with as little pressure as humanly possible.

This is exactly how little force you need to apply to the go-pedal of the B5 to accelerate from a standstill to 60km/h in about five seconds.

If anything sums up the driving experience of the B5, it's that sense of effortlessness.

Stomp on that accelerator, and you'll be shot to 100km/h in 3.5 seconds, without a hint of broken traction thanks to the all-wheel-drive system.

The ride should have been terrible on 20-inch wheels shod in low-profile rubber (Pirelli P Zero 255/35 front, and 295/30 rear), but the Alpina-tuned air suspension is close to miraculous in the way it cushioned and censored the potholes out of Sydney's worst roads. Yes, it can be a touch floaty, particularly in the Comfort Plus setting, but this is benchmark-setting stuff for a comfortable ride.

Don't expect this beast to roar. Unlike the M5, the B5 gets its work done without deafening everybody around it. Sure, the B5's V8 sounds amazing when you push it, but it's not brash, not loud and not lairy. Buy an M5 or Mercedes-AMG E63s if you want to be heard half a block before you get home, but you won't get that with the B5 and its exhaust system.

The B5 also handles well, but I have to say the engagement factor is low. I piloted it effortlessly through the twists and turns of my country test circuit and roads which normally have me grinning like a maniac behind the wheel had me feeling a bit disconnected in the B5. That air suspension, the numb steering and pedal actions make it difficult to ‘feel' the road.

It's highways where the B5 is a king, but even at 110km/h there's the sense that this car is still fast asleep and won't get out of bed for anything less than 150km/h - making it perfect for Germany's autobahns, but maybe not for here in Australia.

The Alpina B5 is based on the BMW 5 Series which had a five-star ANCAP rating awarded to it in 2017.

Along with the comprehensive suite of airbags, traction and stability control, there's an impressive array of advanced safety equipment. Coming standard is AEB (front and rear), evasive steering, front and rear cross-traffic warning, blind-spot alert and lane-keep assist. The Alpina B5 also comes with BMW's emergency call function.

For child seats you'll find two ISOFIX mounts and three top tether points across the rear row.

If you're unfortunate enough to get a flat tyre, there's a puncture repair kit in the boot which works provided the hole isn't giant, as I've experience in the past with these systems.

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. 

The Alpina B5 is covered by BMW's three-year/unlimited kilometre warranty. Servicing is recommended every 12 months or 15,000km.
