2020 BMW Alpina B5 vs 2019 Audi A7

What's the difference?

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.

The Audi A7 is a really likeable car, one that is heavily focused on style but also emanates substance. The 55 TFSI model will appeal to many, but my initial impression is that the best buy in the range could well be the entry-level 45 TFSI. I can't wait to sample it sometime in 2019.

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.

If you can't find something interesting about the design of the Audi A7, there's a good chance you're visually impaired.

The original A7 Sportback was perhaps ahead of its time in the way it blended the lines of a coupe with the practicality of a big sedan, and the new second-generation version pushes the envelope even further into the future. The vision, according to chief designer Andreas Koglin, was "a clear form with sharp lines and tight shapes", including the distinguishable 'boat tail' at the rear.

This is a technologically advanced looking car - big, long, sleek and stylish. From the LED headlights (or matrix LED and laser lights - yes, frikkin' lasers that have the same 5500 Kelvin as the sun, according to Audi) and daytime running lights, to the long, lean LED tail-light assembly, there's an illuminated, enlightened air to the A7.

Plus, with the matrix lights, both ends of the car do a sort of disco sequence as part of the start up and shut down procedure for the car.

There are a few carefully balanced lines across the body of the A7 that help catch the light, which is something you can't really say about its closest direct rival, the Mercedes-Benz CLS. It still retains the 'big-metal-small-glasshouse' look of the existing model, but there are definitely more angles and interesting elements to this new-generation car.

There are two exterior types offered for Australia - the S line that you see here is the version that'll be fitted to the two higher grade models, while the entry-grade model gets a less aggressive look to its front and rear bumpers. To my eyes, the base car actually looks more luxurious, where the S line models - when not fitted with the optional black exterior styling pack that deletes the chrome trims outside - have a slightly uneasy look in the grille area. With a black edge to the single frame grille, it looks a touch more convincing.

The A7 is still large, at 4969mm long (-5mm) and riding on a longer 2926mm wheelbase (+12mm), spans 1908mm wide (2118mm including mirrors), but it's also a little bit taller, at 1422mm (+2mm). According to Audi, the interior space has been increased by 21mm in this generation, making for a more luxurious cabin than before.

Things are a little edgier in terms of design in the cockpit, too. Gone is the appealing wraparound dashboard design, with a more driver-focused treatment evident. It looks sharper, more shapely, and has improvements to the usability inside, too.

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.

According to Audi, the A7's interior is said to offer a "futuristic lounge type ambience". And if your vision of a lounge in the future includes beautiful textile finishes, quality trims, and your choice of three crisp screens to look at and interact with, it certainly lives up to that.

Unlike the existing model, which seemed to draw a bit more inspiration from the world of watercraft, the new model isn't as luxe looking, with a more tech-focused approach inside. The wraparound finish on the dash is gone, and everything is more driver-centric in its orientation - the screens are tilted just enough towards the pilot and the design of the dashboard helps anchor the person in the driver's seat as the most important in the car.

As a driver, I still struggle to come to terms with climate controls that require you to use a screen, and I think it's distracting, too. At least with the Audi screen there's the possibility to slide up or down on the temperature display to make quick changes, rather than having to tap the screen repeatedly.

The haptic feedback on the screens is something that does take a bit of getting used to, because the response time isn't as instant as some regular touchscreen systems, but the menus are all pretty logically laid out.

And of course, all the storage considerations are dealt with, including good cupholders between the seats, decent door pockets, some loose item caddies and so on. In the back there's a flip-down armrest with cupholders, bottle holders in the doors and map pockets on the seat backs. One really neat addition is illuminated seat belt buckles - clever!

Space back there is mostly good, but it's better if you're short. There's enough legroom and shoulder-room for three adults, but anyone taller than me (I'm 182cm) will likely lack some headroom due to the curvaceous roofline.

The boot is good at 535 litres - enough to deal with two golf bags, the brand claims. The shape of the boot means tall items mightn't fit, but the length and width is good, and you get tie-downs with a mesh net to keep things in order. And there's a space-saver spare wheel under the boot floor.

There are three models in the range, and considering the most natural competitors to the Audi A7 - the Mercedes-Benz CLS (from $136,900) and the BMW 6 series GT (from $123,500) - there's an argument that this car is something of a bargain. Ahem. 'Bargain' is relative, clearly.

The entry-level model is the 45 TFSI, which lists at $113,900 plus on-road costs. That's pretty close to the existing starting point for the A7, but now there's a bit more gear included as standard. It doesn't arrive until around the middle of 2019, though.

This model is comprehensively kitted out, with standard inclusions consisting of 20-inch alloy wheels, adaptive suspension, Audi's 'progressive steering' system, LED headlights with high-beam assist, an electronic tailgate with smart opening, keyless entry and push-button start, 'Valcona' leather trim and sports front seats, electric front seat adjustment and front seat heating and three-zone climate control air conditioning.

Other goodies include an LED interior ambient lighting package, head-up display, Audi's 12.3-inch 'Virtual Cockpit' digital driver information display, a 10.1-inch media screen and 8.6-inch control touchscreen, Bluetooth phone and audio streaming, USB connectivity, Apple CarPlay and Android Auto phone mirroring, and wireless smartphone charging.

Next up the model range is the 55 TFSI, which has a list price of $131,900 before on-road costs - which is the exact same price, and carries the exact same level of standard specification, as the diesel-powered 50 TDI model (also due mid-2019). This splits the difference between the existing models, but still undercuts the rivals by a good margin.

Over the entry-grade model, the 50 TDI and 55 TFSI models bring matrix LED headlights (with light animation), a different 20-inch wheel design, the S line exterior styling pack - essentially a body kit with new front and rear bumpers incorporating mesh-look diffusers and new side sills, plus S line badging.

These two models also get different interior styling, too, with S line embossed leather seats, illuminated door sill trims, a flat-bottom leather wheel with paddle shifters, dark brushed aluminium inlays, stainless steel faced pedals, black headlining, piped floor mats, electric steering column adjustment and a Bang & Olufsen 3D 705-watt sound system with 16 speakers and subwoofer.

There's a lot of safety kit included at each price point, too - see the section below for a breakdown.

Audi has tried to simplify things in terms of optional gear - apparently its customers said there was too much complexity when it came to electing bits and bobs, so the company's local arm has just one optional package... and a few other items it says are very much "buyer specific".

The 'Premium Plus' package costs $6500 for the 45 TFSI and $8000 for the other two models (and you get air suspension included in those grades). Across all grades the pack adds 21-inch alloy wheels, tinted rear glass, a panoramic glass roof, an extended upholstery package, four-zone climate control with rear touch control panel, plus a colour interior lighting package with up to 30 colours.

Other options include metallic paint (up to $2200), a four-wheel steering system ($4200) and laser headlights ($2500).

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.

All three drivetrains offered in the A7 have some form of mild hybridisation. The entry-level 45 TFSI engine is a 2.0-litre four-cylinder turbo producing 180kW of power (at 5000-6000rpm) and 370Nm of torque (1600-4500rpm). It has a 0-100km/h claim of 6.8 seconds, and employs a seven-speed dual-clutch auto with quattro all-wheel drive. It employs a 12-volt mild-hybrid system to assist with stop-start traffic and uses brake regeneration, too.

The high-spec petrol is the 55 TFSI, a 3.0-litre V6 producing 250kW (at 5000-6400rpm) and 500Nm (1370-4500rpm). The 0-100 claim is 5.3sec, and it also uses a seven-speed dual-clutch auto. It has a 48-volt mild-hybrid system that uses a larger capacity battery and a belt-driven starter generator that recuperates energy in stop start traffic and, according to Audi, can also allow the car to coast for up to 40 seconds at speeds of 55-160km/h.

The same 48-volt tech is used for the only diesel model in the range, the 50 TDI. This powertrain uses a 3.0-litre turbo-diesel engine producing 210kW (3500-4000rpm) and 620Nm (2250-3000rpm), and unlike the petrols, it has an eight-speed automatic (not a dual-clutch). The claim for acceleration is 5.7sec from 0-100km/h.

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 mild hybrid tech in each of the A7 models help it offer miserly fuel consumption.

The 45 TFSI model claims 7.1 litres per 100 kilometres; the 55 TFSI model just a touch more, at 7.3L/100km. And as you might expect, the 50 TDI diesel model is the most efficient, using a claimed 6.0L/100km.

We only drove the 55 TFSI on test, and the dashboard indicated display of 9.1L/100km seemed pretty respectable.

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.

A lot of the time when we go on new car launches the test drive route is planned to highlight handling dynamism, with less focus on the day-to-day drudgery most of us will actually encounter.

The launch of the Audi A7 was primarily of that design, too, but (thankfully?) there was some disgusting traffic to deal with on our in and out of Brisbane, where it was clear the A7 is superbly comfortable.

Well, that is, if you get the air suspension system. The ride was impressively cushioned, untroubled by sharp edges and road joins, and the suspension eliminated pothole effects, too. All the cars I drove on the launch were the 55 TFSI model, and all had the air suspension - the cynic in me thinks there's probably a reason for that, and I'd love to sample one without it.

This stint of stop-start driving saw the engine cut out at speeds up to 22km/h when you're decelerating, allowing us to coast to a stop without the engine burning fuel.

Once we exited the city limits and found ourselves on the roads of Mt Nebo and Mt Glorious, the chance presented itself to push the A7 in some bendy bits. With the dynamic drive mode selected, the transmission in sport mode, and about a hundred corners to contend with, the big German luxury hatch showed its skills.

The air suspension kept the circa-1815kg model relatively flat in the bends, but the front seats lacked adequate side bolster support despite being called 'sports' seats. Obviously physics were at play here.

The steering was more eager in the four-wheel steer version we sampled, and that's definitely an option for the enthusiastic owner to consider. Otherwise, the steering was accurate, if devoid of meaningful feel.

And while the engine was strong in its response and the transmission clever in its shift speed and intelligence, it became clear that this was a car that seemed more adept at open road cruising than bruising a series of hairpins. It didn't disappoint in terms of dynamics - it just felt its size.

Eventually when we reached an open road, the effortlessness of the A7 came to the fore. Comfort mode engaged, it paced along beautifully, the adaptive cruise taking its surroundings in nicely. There is a touch of wind noise and the suspension can be loud when you encounter pockmarked sections, but it doesn't feel flustered at speed.

One of the nice elements of the A7's smarts is that it will pulse the accelerator pedal to warn you that you could be saving fuel - say you're approaching an 80km/h zone, and you're driving at 100km/h, the throttle will throb to let you know you could ease off. Neat.

At the end of our day of driving, I was left with the impression that the Audi A7 is more than capable as a luxury saloon, one that was relaxing to drive - even when we encountered a five km traffic jam on the way back into Brisbane. It feels well engineered, without excessive gimmickry and with enough genuine quality to leave you feeling pampered.

The Audi A7 doesn't have a five-star safety rating from either ANCAP or Euro NCAP. It's hard to see it not getting that rating, if it were to be tested, because every trim grade has an array of high-tech safety equipment.

The A7 is fitted with a surround-view camera system (360 degree camera) and there are front, side and rear parking sensors, as well as Audi's version of auto emergency braking (AEB) which it calls 'pre sense' - and it operates up to 250km/h.

There's also a reverse AEB system, lane keeping assistance, blind spot monitoring, cross traffic alert (front and rear), and there's adaptive cruise control with traffic jam assist (allowing semi-autonomous driving up to 60km/h), a system that'll stop the car if it doesn't think you can make a gap in the traffic (Intersection Assist) and a system that prevents you from opening your door into the path of cyclists, pedestrians or oncoming traffic.

There are dual ISOFIX child seat restraints in the back, as well as three top-tether attachments. The A7 has dual front airbags, side airbags front and rear, and curtain airbags (Audi claims a total of 10, but by most other makers' counts, that'd be eight).

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

As with all Audi models, there's a three-year/unlimited kilometre warranty offered. Mainstream brands seem to be pushing to five years' warranty, while the premium makers lag behind.

The company also offers a three-year pre-purchase capped price service plan called the 'Audi Genuine Care Service Plan', which you can bundle into your finance package. Exact pricing isn't known yet, but you can expect it to average out at about $650 for every 12 month/15,000km service (based on the previous generation model).
