What's the difference?
Audi’s flagship is the A8, a long, luxurious sedan where being driven is often as important as doing the driving.
To put this ultra-premium machine in context, it competes with other German heavyweights like BMW’s 7 Series and, of course, the Mercedes-Benz S-Class as well as Porsche’s Panamera. Not to mention the Lexus LS or Maserati’s Quattroporte.
What’s life like at the top of the Audi pyramid? Stay with us to find out.
There’s no point waxing too lyrical here, because the facts surrounding the M3 Touring are more than exciting enough.
It’s a (kind of) family friendly wagon with oodles of space and practicality. It’s also an unhinged performance weapon with a thumping 3.0-litre twin-turbo-petrol inline six-cylinder engine.
And it has been years — decades, even — in the making. So, has it been worth the wait? Let’s strap in and find out.
The Audi A8 swims in a luxury car shark tank where those paying the big dollars expect top-shelf everything. It delivers a serene driving experience whether you’re in the front or the back, in a superbly engineered and executed luxury sedan package. Not perfect, but very, very impressive.
Long live the mighty wagon. The BMW M3 Touring is treat to look at, and an even bigger treat to drive.
If you want one, act fast. We waited a long time for a wagon-shaped M3, and with electrification increasing in the automotive industry, this will likely be your last chance.
The A8 is close to 5.2 metres long, yet instantly recognisable as an Audi thanks mainly to its evenly weighted proportions, gently curved roofline and overall high-waisted design. Worth noting its drag coefficient (Cd) is an impressively slippery 0.25.
The characteristic look is accentuated by the brand’s signature, six-sided grille, in this instance highlighted by a matrix of high-relief chrome accents. And typically angular LED Matrix headlights sit either side.
Check out our video review for the carefully orchestrated animation they run through when the car is unlocked.
The car looks equally svelte and contemporary from the rear, with just the right amount of chrome lifting the tone and multi-spoke 20-inch rims filling the wheel arches nicely.
As you’d expect, the top-shelf look and feel continues inside with the seats trimmed in aniline leather, perforated on the front and outer rear positions, with genuine hide also covering the centre console, door rails and armrests, steering wheel and upper dashboard.
Fine grain ash wood inserts sit alongside brushed metal elements and a meticulous attention to detail is obvious… everywhere.
For example, the interior door handle design has been thoroughly thought through, requiring a simple underhand tap to open the door, rather than the more conventional, and ergonomically convoluted, ‘over the top’ movement.
Three sleek screens dial up the tech - a 10.1-inch multimedia interface at the top of the centre stack, an 8.6-inch display below it for heating and ventilation, and a 12.3-inch version of Audi’s ‘Virtual Cockpit’ in the instrument binnacle.
And the spacious rear is the epitome of cool, calm Teutonic form and function. You feel relaxed the moment you get in, and isn’t that the primary aim of a car like this?
It looks spectacular, this M3 Touring, and even more so given a) wagons are so rare, and b) proper low-riding performance wagons with massive alloys are even rarer.
That said, I expect it will be polarising – and possibly too shouty for some – but I've got to say, I like it.
I’ve seen it described elsewhere as a bit of a sleeper, but for mine, you’d need painted-on eyes to not see there’s plenty going on with the Touring, especially one finished in the same Frozen Black paint as our test car.
It is at once sleek and swept back, and bulging and aggressive, especially at the flared wheel arches and fat exhausts poking from its diffuser-filled rump.
Inside, it’s mostly business as BMW usual, though with more carbon-fibre elements — our vehicle was equipped with the M Carbon Experience pack — but snug-fitting seats aside, it’s a premium, if performance-focused, place to spend time.
Space is luxury, be it a large house, a first class seat or a spacious car, and at nearly 5.2 metres long with a close to 3.0m wheelbase the Audi A8 measures up.
Even before you get in, the doors have an amazing sense of solidity and quality. It’s like opening and closing a bank vault… if that huge circular door had a power-assisted soft-close function.
There’s copious amounts of space for the driver and front passenger with lots of storage including a lidded box between the front seats, complete with a two-piece longitudinally split top design, so you can sneak your half’s open without displacing your neighbour’s elbow.
The door bins are decent but there isn’t a specific cut-out for bottles, so it’s more a case of laying them down than standing them up. There’s also a handy covered cubby at the end of the door armrests.
The glove box is a good size and there are two cupholders under a pop-up cover in the centre console.
Of course, the back is where space really counts, and there’s as much room as you’d find in, well… a limo.
Sitting behind the driver’s seat, set for my 183cm position, I enjoyed copious amounts of head, shoulder and legroom.
There are electric sunblinds for the rear and rear side windows, controlled by buttons in the door as well as the rear seat remote, a 5.7 inch OLED display housed in the beautifully trimmed fold-down centre armrest (which also has a soft close function!). The remote also allows adjustment of the lighting and climate control. Classy.
There’s a shallow storage box and twin cupholders in the armrest, medium size door bins and hard shell pockets on the front seat backs. The rear armrests also feature a small lidded cubby.
In terms of connectivity and power options there’s wireless Android Auto and Apple CarPlay, a USB-A and USB-C in the front, and an identical pair in the rear, as well as a 12-volt socket in the front and two in the back.
Boot volume is a useful 505 litres (VDA) and the lid is electric, with gesture control. It’s able to easily swallow our three-piece luggage set or the bulky CarsGuide pram. And while the rear seats don’t fold there’s a ski port door to accommodate long items. Just make sure you use the tie-down anchors in the boot to ensure they’re properly secured. There’s a handy netted section behind the left wheel well and a cargo net is included.
Maximum towing capacity, for a braked trailer, is 2.3 tonnes (750kg unbraked) and in more good news, the spare is a space-saver rather than the increasingly prevalent inflator/repair kit.
A performance-focused wagon is still a wagon, right? And that means there is oodles of space in the boot, though the seating choices in our test cars made the front seats less comfortable than they could, and should, be.
But first, the boot. The M3 Touring is a 4.8m-long wagon, which pays dividends when it comes to cargo. BMW says you'll find a minimum 500L of storage space, which grows to 1510L with the rear seat folded.
In the back, you’ll find seating for three, with the requisite ISOFIX attachment points, and with enough head and leg room to get comfortable.
But those carbon front seats are an option I wouldn’t be springing for. They arrive carved out of the rock-hard material, though with big holes throughout to reduce their overall weight, and they’re not only challenging to climb in and out of, but they’re awkward and hard to sit behind.
Stick with the regular seats and both rows will be happier.
With an entry price of $202,700, before on-road costs, the A8 is in the thick of it amongst its full-size primo sedan competitors from Europe and Japan. Specifically, BMW’s 740i MHEV ($272,900), the Lexus LS500h ($195,920), Maserati Quattroporte GT ($210,990), Mercedes-Benz S450 ($244,700) and Porsche’s Panamera ($207,800).
By definition, a luxury car should be loaded to the gunwales with features that make life on the road that little bit easier. And aside from the performance and safety tech we’ll cover shortly, the highlights from a very lengthy standard equipment list are - 20-inch alloy rims, metallic paint, adaptive cruise control, digital matrix LED headlights, digital OLED tail-lights, full keyless entry and start, power-assisted door closing, power boot lid (with gesture control), a panoramic sunroof, heated, ventilated and massaging electrically adjustable front seats, heated front armrests and extended leather trim (centre console, door rails and armrests, steering wheel and upper dashboard).
Also included are ambient interior lighting (with 30 colours and six colour profiles), four-zone climate control, electric sunblinds for the rear and rear side windows, ‘Audi Connect’ navigation and multimedia (with voice and handwriting recognition), wireless Android Auto and Apple CarPlay, 17-speaker 730-watt Bang & Olufsen audio (with digital radio) and a colour head-up display.
There’s a lot more, and the A8 can hold its head high in terms of pricing and features relative to its $200K price tag and the competition.
The BMW M3 Touring lists at $180,100, which isn’t chump change, and positions the wagon body shape a fair way above a regular M3 sedan.
That’s before on-road costs, of course. According to BMW’s website, putting an M3 Touring on the road in NSW will be more like $194,039 — before you start ticking option boxes.
The 'M Carbon Experience' adds $17,500, and reduces overall weight by close to 10kg through carbon bucket seats, and adds more visible carbon and even more possible headroom to fit a helmet
The 'M Carbon ceramic brakes' add another $16,500, and while there are plenty of free paint colours, you can pay up to $7000 for the 'Frozen White' paintwork.
Our test car was finished in 'Frozen Black', a bargain at $5K.
Elsewhere, there is plenty of equipment on a stacked standard features list.
That includes staggered 19- and 20-inch alloys, BMW’s digital 'Laserlight' headlights, and an automatic boot.
Inside, there’s a 'BMW Live Cockpit' with a 12.3-inch instrument display, a 14.9-inch central screen, a head-up display, wireless device charging, Apple CarPlay and Android Auto and a premium Harman Kardon surround sound stereo.
You also get three-zone climate, leather seats, an 'Active M Differential' and 'Adaptive M Suspension', and seat heating up front.
Oh, and there is lots — lots — of performance, but we’ll come back to that shortly.
The Audi A8 50TDI is powered by a 3.0-litre turbo-diesel V6 engine sending 210kW (from 3500-4000rpm) and 600Nm (from 1750-3250rpm) to all four wheels via an eight-speed automatic transmission (with ‘Tiptronic’ sequential manual shift function) and Audi’s quattro constant all-wheel drive system using a self-locking centre differential.
It also features a 48-volt electrical set-up for mild hybrid functionality built around a belt connected starter/generator, AC to DC converter and a 48-volt lithium-ion battery.
With energy recovery of up to 12kW from regenerative braking, it enables the A8 to regularly coast with the engine switched off and helps the extended stop-start system to operate smoothly.
The M3 Touring’s engine might well be one of the best in the business – a hard-charging 3.0-litre twin-turbo-petrol inline six-cylinder engine that produces a sizeable 375kW and 650Nm.
That power is sent to all four wheels via BMW’s 'M xDrive' with Active M Differential, producing a sprint to 100km/h of just 3.6 seconds.
Audi’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 6.6L/100km, the 3.0-litre turbo-diesel V6 emitting 175g/km of CO2 in the process.
Over a week of city, suburban, and some freeway running we averaged 11.1L/100km, which is acceptable for a 2.1-tonne luxury sedan.
Also worth noting the standard stop-start system works beautifully thanks to the 48-volt starter/generator.
You’ll need 82 litres of diesel to fill the tank and using the official number, that translates to a range of just over 1240km, which drops to around 740km using our real-world figure.
Officially, you should see a claimed 10.4L/100km on the combined cycle, but as is often the case in cars with engines that tempt you to be aggressive with the accelerator, the reality can be a little different.
We saw more like 16.4L/100km, but in the big bruiser’s defence, we spent a lot of time in city and suburbs, and a lot more time standing on the accelerator.
The M3 Touring is fitted with a 59-litre tank, and will only accept 98RON premium fuel.
Range is close to 570km using the official consumption figure and around 360km using our real-world number.
Despite extensive use of aluminium in the ‘ASF’ platform and body panels, the A8 tips the scales at a sturdy 2095kg, yet Audi says the A8 will accelerate from 0-100km/h in just 5.9 seconds. And with 600Nm of peak torque available across a flat plateau from 1750-3250rpm this big four-door gets up and goes hard when asked to.
At more sedate speeds you’re occasionally reminded there’s a diesel engine under the bonnet, with that characteristic engine and exhaust noise only making their presence felt under pressure.
In fact, under normal circumstances, noise, be it the engine, tyres or wind is minimal, thanks to a combination of the car’s aero-efficient shape, thick acoustic glass and other sound-deadening measures throughout the car.
The eight-speed auto transmission is suitably smooth, with the central shifter or wheel-mounted paddles able to make snappy sequential ‘manual’ shifts.
There are four drive modes in the ‘Drive Select’ system - ‘Comfort’, ‘Auto’, ‘Dynamic’ and ‘Individual’ - enabling tweaks to the steering, transmission, throttle and suspension. Comfort felt most appropriate most of the time, although dialling up the throttle and transmission to more aggressive modes in Individual adds an enjoyable edge.
The suspension is five-link front and rear with an adaptive air system smoothing even high-frequency bumps and ruts amazingly well.
Push into a corner and the A8 feels nicely balanced, its wide track, sophisticated suspension, plus the quattro AWD system seamlessly distributing drive between the front and rear axles, keeping the big body under control. In fact, you feel the ‘big car shrinking around you’ syndrome from the get-go.
The steering is precise without being overly sharp and road feel is good. Again, with that 2.1-tonne kerb weight in mind, braking is appropriately powerful with big ventilated discs front (350mm) and rear (330mm).
It pays to remember the turning circle is 12.5m, and it’s worth picking your spot for a U- or three-point turn.
Although there’s a lot going on for the driver in terms of screens, buttons and switches it all makes sense ergonomically. The head-up display is helpful and there’s a common sense mix of digital and physical controls, the latter including an audio volume knob. Yes.
In a word? Delightful.
Don’t get me wrong, it’s not the easiest car in the world to daily drive. The carbon-fibre seats fitted to ours, for example, made getting in and out a slightly embarrassing challenge, and there’s a surging eagerness to the delivery of power that makes you look a little like you're showing off.
But the adaptive suspension serves up a far more comfortable ride than you might be expecting (more comfortable, in fact, than lesser, cheaper M models), making tootling around town easier and less chiropractic than I was expecting.
But it’s away from the city, with its traffic and red lights, that owning the M3 Touring becomes a delight, from its potent and punchy powertrain to the thrum of its exhaust, and the EV-like immediacy of its power delivery.
This is a driver’s wagon, there’s no doubt about it, with proper seatback-pushing acceleration, direct and confident steering and enough body stiffening and bracing that you really would have no idea you’re driving a wagon when cornering.
Engage its sportiest settings, and disengage its electronic nanny systems, and you can even set to work judging your drifting skills, courtesy of the (as yet untested, honestly) 'M Drift Analyser'.
A family car like few others, then. That you can also take it to Bunnings and throw some sleepers in the back is just a very welcome bonus.
Even though the A8 hasn't been assessed by ANCAP, as you might expect, it goes to town when it comes to active safety tech, the car’s standard crash-avoidance features including auto emergency braking (AEB) (pedestrians/cyclists - 5.0-85km/h, vehicles - to 250km/h), ‘Active Lane Assist’, blind-spot monitoring, a reversing camera and 360-degree view (including kerb view function), front and rear parking sensors, ‘Collision Avoidance Assist’ (steering assistance in critical situations), ‘Turn Assist’ (monitors incoming traffic when turning right), and rear cross-traffic alert.
There’s also ‘Intersection Crossing Assist’, ‘Attention Assist’, tyre-pressure monitoring and an ‘Exit Warning System’ (detects cars and cyclists when opening doors).
If all that isn’t enough to avoid a crash the airbag count runs to nine, including front and side bags for the driver and front passenger, side airbags covering the outer rear passengers, full length curtains and a front centre airbag to minimise head clash injuries in a side impact. A first aid kit, warning triangle and high visibility vests are also on-board.
There are three top tethers for baby capsules/child seats across the back seat with ISOFIX anchors on the outer positions.
Neither the M3 or M3 Touring have been independently crash tested to date, but it’s worth pointing out the 3 Series and 4 Series received maximum five-star scores from Euro NCAP.
Standard safety kit includes AEB with pedestrian detection, active lane keeping assist, blind spot monitoring, adaptive cruise control and rear cross-traffic alert.
You’ll also find six airbags on board.
The A8 is covered by Audi Australia’s five-year/unlimited km warranty, which is now par for the luxury market course, and 24-hour roadside assistance is included for the duration.
Paint defects are also covered for five years, with rust (to the point of perforation) covered for 12. Nice.
Service is required every 12 months or 15,000km with a five-year capped-price plan for the A8 coming in at $3830, or $766 per year. That’s a fair wedge but not outrageous for the category.
The BMW M3 Touring is covered by a five-year, unlimited kilometre warranty, and servicing is "condition based", in that the vehicle will tell you what maintenance is required, and when.
You can prepay your service costs at the time of purchase for all BMW vehicles, covering the first five years of ownership.
