Porsche Panamera vs BMW Alpina B7

What's the difference?

The Panamera is the ‘have your Porsche and drive it too’ model.

It encompasses the fun of the 911 while still being a comfortable daily driver that can easily fit a family of four. The cabin is sumptuously styled and not hurting for features, either.

Could the ownership costs and storage be better? Probably, but if you’re looking at this model, those items will probably be lower priorities for you.

For my little family of three, the base model Panamera is a win.

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.

This is more than just a new Panamera - it’s a new generation Panamera.

The outgoing model was sort of a mix between the 911 and Macan but didn’t really hit the mark with any of its borrowed elements.

Beauty is in the eye of the beholder but the redesign sees this model get an outward appearance that looks far more aggressive with a distinct profile that now sets it apart for all of the right reasons.

On the outside, the biggest changes include larger matrix LED headlights and a new front fascia that sits a bit higher with more pronounced curving in the bonnet.

The front gets extra air intakes but there are also larger 'air blade' vents behind the front wheel arches which help smooth the air flow around the wheels and add some extra sculpted sportiness to the car's sides.

The rear has been reshaped to look more like the 911 and isn't as pillowy as the outgoing model. There is a new long LED strip light running the width of the rear and an extra brake light for added dazzlement at night. The rear window now spreads to the width of the liftback lid which makes it appear frameless.

The optioned 21-inch alloy wheels look gorgeous in their painted bronze (or Neodyme) glory and feature the Porsche crest in full colour for added pizzazz. The bronze accent is also carried across to the quad exhausts.

All these factors make the exterior design look more cohesive than the previous model.

The interior has been reworked, too, and the dashboard now sports upgraded tech panels that makes the cabin feel cinematic. The optioned passenger display screen only adds to this effect.

Purists will pout, but like the new 911 the analogue cluster and turn-key operation have died a quiet death. You now get a 12.3-inch digital instrument panel and push-button starter. Plus, the gearshift has been repositioned from the centre console to the dash.

The optioned Sports Chrono and Neodyme accent packages of our test model means the dashboard gets a race clock (superfluous for every day driving but fun to look at) and the door handles, steering wheel and dashboard feature the same bronze highlights.

The only elements that don't look the part are the shiny piano black panels mainly found in the centre console. They're too easily scratched/marked for a car at this price point.

The cabin may not be as flashy as its competitors but it's still sumptuous.

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 cabin feels spacious in both rows and the rear row can comfortably fit those who are above six foot (182cm) with a caveat.

Despite being optioned with the '4+1' seating, don't be fooled; the middle rear seat is nothing more than extra room for the out-boarders as the rear centre console takes up all legroom a middle seater might need. Not even a kid will be happy in the middle for long.

Amenities in both rows are good. The heating/cooling and massage functions on the front seats are great and the four-zone climate control means everyone can get comfortable.

Access to both rows is surprisingly good with doors that open widely but the rear footwell lip is high and the well narrow. So, if you have clunky boots on you may feel clumsy getting into position.

My seven-year old found the doors heavy to open and it took him a while to realise he didn’t have to slam the doors shut thanks to the soft-close feature.

Individual storage is better than you usually get in a sports car but all cubbies still fall on the shallower side. There are four cupholders, four drink bottle holders, a glove box, a middle console and two small net map pockets. There is also a dedicated phone cubby housing the wireless charging pad.

The boot aperture is wide and it’s super easy to reach things in the back thanks to the liftback lid but that sloping roofline means you lose out on height for larger items.

Stack bigger things right behind the back seat if you want to fit them. Capacity is below average compared to its rivals at 460L.

The rear row has a 40/20/40 split to open up storage options and there is a very deep cubby underneath the floor with the tyre compressor/repair kit.

Device charging options are great with a total of four USB-C ports, a wireless charging pad and three 12-volt sockets to choose from.  

The upgraded multimedia system looks fantastic and is user-friendly. The built-in satellite navigation is simple to use and the multimedia system, head-up display and instrument cluster can be highly customised.

The base Panamera model now comes standard with wireless Apple CarPlay and Android Auto. Connecting to the CarPlay is easy and the connection remains seamless.

The optional passenger display panel allows the front passenger to control their climate and seat comfort, see a duplicate of the instrument panel or just watch a movie on a long trip.

The screen has a privacy filter, which means the driver can’t see what’s on it and is thus not a distraction. However, no one in my family bothered to use it.

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 base Panamera doesn’t have a hybrid powertrain like its siblings and sports the 2.9L V6 twin-turbo petrol engine of the outgoing model. But it’s been retuned and now produces 260kW and 500Nm – both figures up from the previous model.

The Sport Chrono Package means the 0-100km/h sprint improves from 5.1-seconds to a tummy-sucking 4.8-seconds and my son gave a whoop of delight whenever we had to get up to speed.

The Panamera has an eight-speed, dual-clutch auto transmission and is the only RWD for the Panamera line-up. It also sports a top speed of 272km/h. So, suffice it to say, the engine has the sports cred you expect from a Porsche.

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.

The official combined (urban/extra-urban) fuel-cycle consumption figure is 9.5L/100km, which is pretty low for a high-performance vehicle (and a big one at that) but after a lot of open road and urban driving my real-world usage came out at 10.9L/100km.

That's the result after not being skimpy with using the power, either, so it's not as thirsty as you might expect.

When it comes to times between fills, the Panamera might surprise you. Based on the official combined fuel cycle and large 90L fuel tank, expect a theoretical driving range of up to 947km (825km using our on-test figure) – which is a great driving range for a performance vehicle, let alone a family one.

The Porsche Panamera only drinks the best, so while the driving range is great you won't be able to fill 'er up with anything but premium 98 RON unleaded petrol.

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.

Some people might not understand the obsession or loyalty Porsche owners have towards their cars  but if you’re a fence sitter, get in the Panamera. It will make you understand because after driving one... you'll hear yourself say 'I get it'.

The base model has the goods with the engine outputs to ensure the driving experience remains fun and responsive.

The Panamera is no wild bronco, it's a cool customer. The composure for power delivery is unlike other performance sedans you may have driven. Acceleration is effortless without any twitchiness. You never feel out of control.

The air suspension means you hear the bumps more than you feel them but you still get excellent road feedback as a driver.

Passenger comfort is high, despite the cabin being quite loud with road and engine noise, because the seat and ride comfort remains well-cushioned. Fatigue and jostling are at a minimum.

The handling of the Panamera when it comes to cornering and steering feels dynamic and agile. I made a point of doing multiple mini roadies this week, simply for the joy of driving it.

While the Panamera is the most fun on a winding mountain road, it's a pleasant open-road cruiser as well.

The base Panamera has three driving modes - 'Normal', 'Sport' or 'Sport Plus' with a 20-second power booster available when you need extra oomph.

The Normal mode is sufficient for daily driving and the Sport Plus offers stiffer suspension and handling but the preference is to keep it in Sport mode.

Mainly because in this mode you get an awesome throatiness from the exhaust as well as the dynamics you expect from a sports car.

It’s a bit deceptive but the Panamera is massive and sits at 5052mm long and 2165mm wide - so, it definitely fills out a parking space!

However, the 360-degree view camera system is one of the best in the segment but you may still get choosy with where you park it.

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.

Porsche offers the Panamera with a three-year/unlimited km warranty, which is less than its competitors. It's more typical to see a five-year/unlimited km warranty in this segment.

Servicing intervals are reasonable at every 12-months or 15,000km, whichever occurs first and pricing varies per dealership.

The one I contacted (in Sydney) confirmed the first four years of servicing costs $8605 for an average of $2151.25 per workshop visit.

Worth noting the fourth year is a biggie at $4875, this major service including everything from an air-conditioning clean and transmission oil change to spark plug check/replacement and safety checks.

The Panamera is up there for service costs, even for the class but this kind of outlay comes with the territory when you're considering a car worth almost $300K. 

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.
