- Australia's speed limits
In a world where genuine wood trim and nappa leather comes in a Mazda6 for under $50,000, premium brands like Audi have been forced to come up with new hallmarks to underpin their status and asking prices.
The new, fourth-generation Audi A8 is no different, packing hardware capable of autonomous driving well ahead of what is currently allowed on any public roads, along with an array of safety, efficiency and convenience firsts for the brand that cement the model's position at the top of the four-ringed luxury tree.
The current S-Class may measure your vital signs and aim to improve your general well-being, but it won't give you a foot massage. If you tick the right options boxes, the new A8 will.
We were among the first to drive the new A8 at its Australian launch around Sydney last week.

BMW Alpina B7
You know when you're walking along the footpath and you come to a soft spongey bit that the council have put in around a tree and your mind goes: "Whoah, the ground is bouncy but it looks just like bitumen?!"
Well that's the kind of response you'll get from people when they think they're looking at a regular BMW 7 Series, only to have their world go a bit bouncy when they see the Alpina B7 badge on the back of this car as you're overtaking them at Warp Factor 9000.
And you will be overtaking them like a blur because, thanks to the elves at German tuning house Alpina, the B7 is hugely fast for a five-seat, 5.3m-long, 2.2 tonne limo. But then the B7 is fast for any type of car of any dimensions, because with its 330km/h top speed this beast will outrun a McLaren 570GT. Yes, seriously.
Based on the BMW 750Li long wheelbase, the B7 begins life rolling down the same production line as a regular 7 Series. Alpina then goes on to make so many changes to the engine and chassis that the German government requires the BMW VIN to be replaced with a new one.
Ready to find out more? Well there's so much to see here that things may go a bit weird and bouncy again. Be prepared.

The new A8 is a very accomplished machine, and can certainly be optioned up with enough toys to entertain and comfort whether you're riding in the front or back.
It's not possible to say if its better than the S-Class or 7 Series in isolation, but it has a unique design ambience that's unmistakably Audi. If you're a four-ring devotee, you won't be missing out.
Based on this test, the sweet spot of the range is the long-wheelbase 55 TFSI. At this end of the market, it's fair to say the extra $12,000 for the added length and $3000 for the smoothest and most powerful engine are worth it.
Regardless of the bigger wheels, we'd probably spring for the Premium plus package and the Executive package's rear seat with the Entertainment package for all the most impressive toys. This would mean a total list of almost $250k, but it's arguably how Audi intended the new model to be.

BMW Alpina B77.9/10
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.
Is the BMW Alpina B7 the ultimate fast limousine? Tells us what you think in the comments section below.
At first glance the new A8's exterior styling may look a tad obvious, with unmistakably Audi design adding a bunch of straight lines to make things look more serious.
The reality is far more considered, being the first whole design to emerge under Audi Design boss Marc Lichte's stewardship. Previewed by the first Prologue concept in 2014, the result has an elegance that underlines its position as Audi's flagship and is less likely to be confused with an A6 than the S-Class can be with the E-Class.
If you're after the ultimate in design details and lighting performance, you can also opt for $13,200 laser headlights that can double the range of LED headlights to 600m ahead. This option also brings OLED tail-lights with jewel-like filaments less than 1.0mm thick.
Compared with the third-generation model it replaces, the size of the new A8 is 37mm longer, 13mm taller but 4.0mm narrower, riding on a 6.0mm longer (2998mm) wheelbase. The long wheelbase version is 130mm longer again in wheelbase and overall.
In A8 guise, it combines aluminium, steel, magnesium and CFRP to result in the biggest material variety used in an Audi to date. Kerb weight ranges from 1995kg for the short-wheelbase petrol model to 2020kg for the long-wheelbase version, with the diesel versions adding 55kg respectively.
A 15-spoke, 19-inch wheel design is standard for Australia, but the Premium plus package fitted to all the cars we tested brings a 10-spoke 20-inch design, while the options list includes another three choices of 20-inch wheels. You can also get 21-inch alloys with the optional Sport package.
As you'll see in the interior images, the A8 represents another significant step forward for Audi design, with horizontal themes and numerous traditional controls now hidden beneath touchpads.
Key among these is the deletion of the centre console controller for the multimedia system, which has been replaced by an 8.6-inch secondary touchscreen beneath the 10.1-inch main screen. Apple CarPlay and Android Auto smartphone interfaces are available via USB connection, and the A8 will act as a mobile Wi-Fi hotspot if you sign up for a data plan.
This split layout is less imposing than using one giant screen as in a Tesla, and both give haptic and acoustic feedback to commands to simplify use while driving. All versions also score the excellent 12.3-inch 'Virtual Cockpit' display ahead of the driver.
All A8s also now get a smartphone-like back seat remote controller, which enables control of temperature settings, seat adjustment, lighting, media functions and window blinds (when optioned) via its 5.7-inch OLED touchscreen.
Another surprise detail is that the interior door handles are now power assisted, which represents the lengths Audi has gone to in reducing control weights.
BMW Alpina B77/10
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.
Choosing the biggest sedan in the line-up isn't just about outdoing your neighbours, it's also fair to expect enough room to stretch out and ponder your stock options.
Despite the new A8's minor 6.0mm wheelbase growth, the interior dimensions have grown 32mm in length, which has expanded legroom as well as headroom.
Fundamental practicality elements are covered as well, with a cupholder and bottle holder for each outboard passenger, an array of USB and 12-volt charge points and two ISOFIX child seat mounts for the back seat. There's also a Qi wireless phone charger within the centre console.
Boot space is a useful 505 litres, and while there's no split-fold for the back seat, there is the capacity to bring curtain rods home from Bunnings via the ski port. There is also a space saver spare wheel beneath the boot floor.
BMW Alpina B78/10
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.
Price and features
The fact that the new A8's entry price has dropped almost $6000 to $192,000 is likely to have less impact than a $19,990 Hyundai i30 special, but Audi's claim that it offers up to $36,000 more value than before may lower a few bifocals.
Introducing Audi's new naming scheme, which no longer makes reference to engine capacity in preparation for electrification, the diesel base model wears a 50 TDI badge, before moving $3000 north to the petrol 55 TSFI. Either models can be had in long-wheelbase form (signified by a capital L after A8) which will cost you an additional $15,000 respectively.
The $210,000 A8 L 55 TFSI at the top of the price list is more than $42,000 cheaper than the previous V8 diesel 4.2 TDI and a more than $120,000 less than the previous S8 Plus, but a new performance flagship is due to appear in the near future.
Value is rather subjective at this end of the price scale, but by comparison the entry RRP for the new A8 undercuts the base 7 Series by $34,900, the S-Class by $3900, but starts $1871 above the Lexus LS.
Both the A8's 50 and 55 engines come with the same trim levels, but when the standard kit is this lengthy it's more a matter of features not included in the A8, rather than those that are.
As you might expect, there's an array of options available. These accessories range from the aforementioned wheel choices and laser lighting to $3600 Alcantara headlining, $4500 all-wheel steering, a $5200 night vision system, or $12,100 3D Bang & Olufsen sound system with 23 speakers.
There are five options packages also, starting with the $6690 'Entertainment package' which brings a six-disc DVD/CD changer (on top of the standard DVD/CD player) and twin tablets for the rear seats which mount to the front seat headrests.
The nappa leather trim can be expanded to the upper and lower dash and glovebox, door trims, headrests, centre console, steering wheel airbag cover and the backs of the front seats with the 'Full leather package' for an extra $9950.
If you can't hold out for the sport edition S8, you can almost look the part with the $9950 'Sport package', which brings a more aggressive front and rear bumper, 21-inch wheels, all-wheel steering and expanded 'piano black' interior trim.
Audi Australia tells us all A8s ordered to date (along with both cars pictured here) have ticked the $11,000 'Premium plus package', which brings 20-inch rims, adaptive windscreen wipers with integrated jets, chrome exterior details, ambient lighting with variable colours, black control buttons, digital TV, electric rear sunblinds, the full leather package mentioned above, interior fragrancing with ionisation technology, rear tinted windows, softer rear headrests and ventilated massage front seats.
If you've already selected the rear seat entertainment system, you can also choose the $18,500 'Executive package' which brings individual reclining back seats and extended centre console - which also eliminates the centre rear seat - with folding tables, front and rear seat ventilation and massage function, heated armrests all round and a heated steering wheel. It's the Executive package that also brings the heated rear passenger-side footrest and the foot massage USP.
BMW Alpina B77/10
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.
Engine & trans
You might be surprised to learn there's no V8 in the new A8's arsenal - for now, the S8 could change that - but an even greater sign of the times is the return of a petrol version for the first time since 2013. Efficiency gains are the main reason for the petrol comeback, which is explained in detail under the fuel consumption heading below.
Both the 210kW/600Nm 50 TDI turbo-diesel and 250kW/500Nm 55 TFSI petrol specifications use 3.0-litre turbocharged V6s which may seem to be simply plucked from existing models, but they bring mild hybrid technology to the Audi line-up for the first time.
Unlike conventional hybrids that use an electric motor to provide horsepower to drive the vehicle, a mild hybrid (or MHEV) enables the combustion engine to be switched off when the vehicle is coasting or braking, or effectively as an extension of a start/stop system which conserves fuel when a car is stationary.
The A8's mild hybrid system is facilitated by the move to a 48 volt electrical system, with a supplementary 10Ah lithium-ion battery mounted in the boot to keep the electrical systems fed for up to 40 seconds with the engine switched off. Audi claims the system has the capacity to save up to 0.7L/100km.
An extra starter motor has been integrated with the alternator to restart the engine more smoothly via a belt, rather than the conventional cog and ring gear used by the dedicated starter motor for cold starts.
Both engine specs deliver their max torque rating from just above idle, with the 50 TDI at 1250rpm and the 55 TSFI at 1370. Claimed 0-100km/h acceleration performance figures are an impressive 5.9s and 5.6s respectively.
Like all recent longitudinal-engined Audis, the new A8 uses a version of ZF's much lauded eight-speed torque converter auto gearbox, and both engines send power to all four wheels via the 'quattro' all-wheel drive system.
The optional all-wheel steer system can twist the rear wheels by as much as five degrees, reducing the turning circle by around 1.0m at slow speeds. While at higher speeds, the rear wheels move parallel with the fronts by as much as two degrees to improve stability, particularly for rapid lane changes and evasive manoeuvres.
All new A8 variants carry a maximum braked towing capacity of 2300kg.
BMW Alpina B79/10
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.
Gone are the days where full-size luxury sedans got away with devil-may-care fuel consumption, and even though they still spin six cylinders and need to move around two tonnes, the 55 TFSI petrol versions manage an 8.2L/100km official combined figure. This is when using at least 95 RON Premium unleaded of course.
As you'd expect, the diesel fuel economy is even better with 5.9-6.0 official figures across wheelbases.
With a fuel tank capacity of 72 litres, this suggests a theoretical range between fills of 878km for the petrol models, and between 1200-1220km for the diesels. The A8's spec sheet lists the option of an 82-litre tank if they aren't quite far enough for you.
BMW Alpina B77/10
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.
Our test started in the worst of Sydney morning traffic, which presented the chance to put the latest adaptive cruise assist (ACA) system through its paces on a very clogged Eastern Distributor.
I'm a huge fan of active cruise control systems that guide the vehicle from speed to a stop, but the A8's ability to start moving again is another step beyond. It helps you avoid being ‘that guy' who hasn't noticed the traffic moving, and would no doubt work wonders for traffic flow if all cars were so equipped. Given the chance, Audi says this system works all the way from 0-250km/h.
No matter what your reaction to the A8's exterior, the freshness of the interior design is like no other, and everything you touch feels first class.
The four-spoke steering wheel has a surprisingly large diameter and is shared with the upcoming A6, but uses thinner spokes than the norm to promote visibility of the virtual cockpit display as the wheel is twirled.
The haptic and acoustic screens make it as easy as we've experienced to handle a touchscreen while driving, but not quite as simple as the previous console controller.
Front and rear seats are softly padded for comfort rather than support, and unsurprisingly there's ample room in every direction for this 172cm tester, regardless of wheelbase.
All examples of the A8 we drove were optioned with the Premium plus package, which means one inch larger 20-inch alloys. Despite all A8s coming standard with adaptive air suspension, small bumps like cats eyes and expansion joints are more noticeable than you might expect. As is often the case, the standard 19-inch alloy wheels are likely to be the solution.
We drove both engines and wheelbase choices at the A8 launch event, and you need to be paying close attention to hear any extra noise from the diesel. It does make a muted groan under throttle, but likely worth the 300-plus kilometres of extra range if that's what you're after.
The diesel's smoothness is also no doubt aided by its use of active engine mounts. If you're after outright refinement and performance, the petrol is the one for you but neither feel in any way sluggish.
Heading through the bends of the Royal National Park and then back over the hills via Macquarie Pass at pace, there was no disguising the fact that the A8 is a big car, and it tends to float unless you select 'Dynamic' from the drive mode selector. Regardless of mode, it's more planted than any luxury SUV.
Making a bee-line back to Sydney via the Hume, the A8 simply wafted along at 110km/h in near silence. As you'd expect.
BMW Alpina B79/10
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 airbag count has been further bolstered by an industry-first centre airbag, which has been designed to prevent head clashes between front seat occupants. This also represents Audi thinking beyond any Euro NCAP or ANCAP criteria.
It also comes with Audi's exit warning system, which warns the driver of passing cars or cyclists but can now delay the door opening in case the driver doesn't see the warning light.
A front-mounted laser scanner replaces the usual radar system for active cruise control and front AEB, which doubles the range of a radar scanner to 80m and enables both functions to work at speeds up to 250km/h.
This laser scanner is also key to the A8's Level 3 autonomous preparation, but local laws limit its capability to active cruise control with lane assist.
BMW Alpina B79/10
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.
Like all Audis, the new A8 is covered by a three year, unlimited kilometre warranty. This is short of the five year-plus periods becoming more common among mainstream brands, but equal to the terms offered by BMW and Mercedes-Benz. Lexus differs by offering a four year, 100,000km plan.
Service intervals and capped price servicing mirror the previous A8, with a 12 month/15,000km schedule, and maintenance costs for the first three services can be wrapped into a package for $1900.
We had no issues during our test, but any common faults, common problems or reliability issues are likely to appear on our A8 problems page.
BMW Alpina B77/10
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.
