Audi A6 vs Subaru Outback

What's the difference?

I was thoroughly impressed by the Audi A6 Allroad 45 TDI quattro 2020 model. It is excellent on road, resolved and comfortable on unsealed surfaces, and very well packaged for family touring.

I’d personally have it in a heartbeat over a Q7 or any SUV, for that matter. I can understand why some buyers wouldn’t consider it, but if you’re someone who likes to think outside of the boxy SUV, then be sure to take a look at the Audi A6 Allroad.

The Subaru Outback Sport Touring XT is what you get when you want a beefed-up station wagon masquerading as an SUV that can handle adventuring and haul the family around in comfort. The limited edition has all of the great features you'd expect from a top model and a reasonable price tag but its fuel thirst will turn some people off.

If this isn’t the best looking genre of car, I must have been blindfolded since birth. You might think differently - be sure to let me know in the comments section below.

But for me, I just love the idea of a station wagon that is beefed up with SUV styling cues, and the Audi Allroad formula has been en pointe for generations now. This latest A6 Allroad doesn’t disappoint, either, with all the elements you’d expect.

Things like the bulging contrasting wheel-arch liners, the rugged underbody protection bash plates, and even the silver roof rails and silver metallic side sill protectors with ‘quattro’ emblazoned upon them - it just all works. 

And being an Audi A6 wagon underneath the glittery bits, it’s a sizeable vehicle. The dimensions read like so: length - 4951mm; wheelbase - 2925mm; width - 1902mm; height - 1458mm, though that depends on the height of the air suspension. 

The A6 Allroad sits about 45 millimetres higher than the standard A6 Avant wagon (not sold in Australia). And the ground clearance also varies depending on the air suspension height setting, but it is officially recorded at 139mm - which isn’t very high at all, but that’s for the regular driving setup. In its raised height, that jumps by 45mm to 184mm. Nowhere near an off-road Toyota, but still high enough to stop the belly from scraping.

And there are other hardware bits to help you out if the going gets tough - out of sight is Audi’s ‘quattro’ all-wheel drive system with a self-locking centre differential that the brand says provides “superior traction and its high level of safety and agile handling”. There is hill descent control, and the infotainment screen can display the location, elevation, compass and driving angles, too.

As for the design of the interior? It’s high-tech Audi opulence and comfort at its best. Check out the interior pictures to see what I mean.

The Sport Touring XT model is only available in the exclusive Geyser Blue paintwork (you'll either love it or hate it), has green accents scattered across the body and sports sharply styled and dark 18-inch alloy wheels.

The rear gets black badging and a spoiler but the black plastic moulding that Subaru is well known for is well and truly present.

There are some small design differences between the limited edition and it's siblings but at the end of the day it looks like an Outback.

Head inside and you'll find a solid and well-built cabin. The dashboard features a flashy 11.6-inch tech screen but the instrument cluster is still mostly analogue with a small 4.2-inch screen.

There are heaps of buttons and dials to play with and you also get a proper gear-shifter. The design will make this a winner for folks who want a car to look like a car, with its controls where they expect them to be.

Overall, the cabin feels premium but isn't fussy.

Technical. Practical. Glorious. Three words I’d use to describe the cabin of the Audi A6 Allroad. 

The cockpit isn’t anything out of the ordinary for an Audi of the modern era, and as such it will feel familiar to you if you’ve been in or around any of its more recent stablemates. It also means that you’ll find yourself in a high-end, high-tech and highly pleasant interior. The materials used are beautiful and of a high standard. They look very nice and it is an extremely pleasant place to be. And you can hate on me if you want, but I’m sold on brown leather. Yummo!

It will take some time for you to get to grips with the dual-touchscreen layout of the cabin, but once you get the hang of it, it becomes second nature.

The media screen is very easy to use, the menus are simple to learn, and over my week there were absolutely no issues with Apple CarPlay - either when connected via USB, or when used wirelessly.

The second screen below controls a lot of the main functions of the air conditioning system, and while I’m not a huge fan of using a screen to touch through temperature and fan controls, this one has haptic feedback and is well positioned - it’s not as much of a glance away from the road as in, say, a Land Rover or Range Rover. There’s also a volume knob which is good, and quick buttons for Drive Select and demister for front and rear windscreens.

In terms of the practicalities, there are bottle holders in the doors, a pair of cup holders between the front seats, a covered centre console bin with Qi wireless phone charging (remember not to leave your phone in there!) and there are two USB ports in there, plus a SIM card slot and SD card slot as well.   

The seat comfort is very good - there’s electric adjustment on both seats with lumbar adjustment, and the driver’s seat gets memory settings as well. The electric steering wheel adjust is a nice touch as well, and there’s a remote boot release trigger, too.

There are twin sunroofs, and the front one can tilt and slide while the rear one is fixed. It helps lighten things up a bit if you have the optional dark headlining, which I personally wouldn’t choose.

Rear seat space is excellent. Sitting behind my own 182cm driver’s seat position, I had easily enough legroom, headroom and shoulder room - in fact, the rear pew is so accommodating, it could easily fit three of me across - but foot space is a little tight due to the large transmission tunnel. 

Those in the back are well catered for – there are 2x USB ports, a pair of large door pockets with bottle holders, twin mesh map pockets, a flip down armrest with storage and cupholders, and our car had quad zone climate control (as part of the optional Premium Plus package - standard is three-zone climate), plus there are centrally mounted directional air vents and in the door pillars at face height. Our tester also had those optional manual sunblinds, which would certainly help those in the back get some shut-eye on longer trips. 

The centre section of the rear seat can be split folded down on its own as well – so you have 40:20:40 rear seat folding, which is great for skis or snowboards. Plus there are two ISOFIX child seat attachments and three top-tether points available for baby seats. And one of the most excellent additions to any car ever – illuminated seat belt buckle receivers. It just makes it that much easier to see at night.

If you need to fold down those rear seats, there are boot-mounted triggers. That’ll help expand the luggage capacity from the standard 565 litres (VDA) to an expansive 1680L (VDA). The cargo hold easily fit the three CarsGuide suitcases (124L, 95L and 36L) with room to spare.

There is no Audi Allroad seven seater, though. And that’s potentially where something like a Q7 makes more sense, depending on your intent. 

The cabin of the Outback has always been practical but the premium features this grade comes with ensures proper comfort for all occupants.

Seat comfort is high with the powered front seats that have heat and ventilation functions but the driver benefits the most with the extendable lumbar- and under-thigh supports.

The rear row is almost as comfortable as the front where passengers feel secured by the padded side bolsters, while taller occupants will love the head and legroom on offer. The heat function for the outboards is appreciated and the directional air vents are easy to position.

The 213mm ground clearance means it's easy getting in and out of the model but access to the back row is a little annoying. The footwell lip sits high and catches unsuspecting feet but it's the doors that made my eight-year-old grumble this week because they're heavy to operate.

Storage up front isn't class-leading but you get a glovebox that fits a manual, a dual-opening middle console, two cupholders and drink bottle holders, as well as a sunglasses holder and small cubby in front of the gear-shifter (which is annoying to access).

Storage is much better in the rear with four map pockets, storage bins in each door, two cupholders and two drink bottle holders to choose from.

The boot has 522 litres of capacity available, which is plenty of room for a road trip or a big grocery haul and the level loading space makes it easy to slide things in and out. You get a proper full-size spare tyre, which is rare nowadays and the powered tailgate is always a handy feature.

Technology feels well rounded and the touchscreen multimedia system is responsive and easy to use. However, the portrait position makes the icons and text on the wireless Apple CarPlay look small and I may have made a few accidental calls this week because of it.

The satellite navigation is easy to use and there's also wireless Android Auto. Charging options are decent with each row getting a single USB-A and C port but the front misses out on a wireless charging pad.

There are usually five variants available for the Subaru Outback but the model on test for this review is a special edition that blends the qualities and features of the top Touring XT but with some exclusive design changes.

Did we need it? Probably not but Subaru has wisely kept the price increase to a minimum, so the AWD Sport Touring XT is $57,490 before on-road costs, just $500 dearer than the usual top grade.

Despite looking more like a station wagon, the Outback sits in the large SUV segment and when it comes to an 'apples to apple' comparison, there's nothing really to compare it to.

With that in mind, the Skoda Superb Sportline wagon costs $74,990 drive-away, and a more traditional SUV like the Volkswagen Tiguan Allspace 162TSI R-Line is priced from $60,590 MSRP.

The standard premium equipment for the Sport Touring XT model includes Nappa leather upholstery, eight-way powered front seats with the driver enjoying additional lumbar and under-thigh support, as well as two-position memory function.

Also included are heating and ventilation functions for the front seats, heat function for the rear outboard seats, a heated steering wheel and sunroof with manual blind.

Technology is well-rounded with an 11.6-inch touchscreen multimedia system with satellite navigation, dual climate control, wireless Apple CarPlay and Android Auto, digital radio, AM/FM radio, two USB-A ports, two USB-C ports, two 12-volt sockets, and a nine-speaker Harman Kardon sound system.

Practical features include dusk-sensing LED headlights, rain-sensing windscreen wipers, keyless entry/ start, a full-size spare tyre and hands-free powered tailgate.

The limited-edition model is well-specified and while it lacks the extra two-seats that its rivals have, it still offers solid value.

Under the bonnet of the Audi A6 Allroad is what Audi labels the ‘45 TDI’ - a 3.0-litre turbo-diesel V6 engine that produces 183kW of power (from 2750-4500rpm) and 600Nm of torque (from 1500-3000rpm).

The engine is only available mated to an eight-speed torque-converter automatic transmission and Audi’s renowned ‘quattro’ all-wheel-drive (AWD) system. 

Audi claims this 1980kg wagon can run from 0-100km/h in just 6.5 seconds, on its way to a top speed of 250km/h. It is a hummer of an engine - more on that in the driving section below.

Towing capacity is pegged at 750kg for an unbraked trailer, and maxes out at 2500kg for a braked trailer.

Should Aussies feel short changed when it comes to the engine options here? Arguably, yes - and that’s despite the powertrain offered here still being a stormer. 

There’s only one spec available Down Under, and even it doesn’t get the most up-to-date emissions tech. There isn’t AdBlue urea treatment (meaning this is a Euro 5 engine), and our cars have essentially been de-specced to miss out on the latest 48-volt mild-hybrid tech, which is standard on all grades of the A6 Allroad in Europe. Maybe that is part of the reason the cost is down, this time around. 

And while the outputs of the 45 TDI in Australia are pretty decent, other markets have the A6 Allroad offered in 50 TDI (210kW/620Nm) and 55 TDI (257kW/700Nm) trims. Remember, though - this is a very niche player here. 

The Sport Touring XT gets a 2.4L four-cylinder turbo-petrol boxer engine that produces a hefty 183kW of power and 350Nm of torque.

The re-tuned continuously variable transmission (CVT) system feels like it is changing gears but it's smooth and punctual, no matter the speed.

Audi claims the 45 TDI powertrain in the A6 Allroad will use 6.6 litres per 100 kilometres. That’s the official Australia fuel consumption figure on the combined-cycle test. CO2 emissions are claimed at 174g/km.

During my time in the Audi A6 Allroad I saw an average fuel use return of 7.4L/100km - which was taken over highways, back roads, unsealed roads and twisty bits. There was even some urban stop-start in there, too. I think that’s pretty darn good for a car of this size.

Fuel tank capacity is 63 litres, meaning a real-world range of 851km based on my fuel consumption.

As mentioned above, the A6 Allroad is a mild hybrid model in other markets, but not in Australia. We don’t even get the Euro 6-compliant version here, as there’s no incentive for it to be offered locally - as in, there’s not even AdBlue treatment. 

There’s no electric version (though you might want to look at the all-new Audi e-tron)  or plug in hybrid, and no petrol model either.

Unfortunately, the turbo-petrol engine is thirsty and the official combined fuel cycle figure is 9.0L/100km.

With its 63L fuel tank, you have a theoretical driving range of up to 700km, which is best-case scenario but expect less range if you’re a city dweller.

After doing a mix of open road and city driving this week, my real-world usage came out at 9.3L, which is better than I expected.

Here’s where the A6 Allroad separates itself from, say, an Audi Q5 or Q7. It’s a low-slung wagon, made for touring on country roads, doubling down on dirt backtracks and cruising comfortably on the freeway.

It’s not as upright as a Q5 or Q7, and that means it has a lower centre of gravity - so it feels more hunkered down, more settled into the surface below.  

And in the case of the A6 Allroad, there’s adaptive air suspension all around to cushion the car from what lies beneath. For the most part, that air suspension is superb - it absorbs big bumps and lumps very well, though the oversized 21-inch optional wheels can’t disguise sharp edges from those in the cabin. 

The general compliance is very good, and as I found out first hand, you can easily soak up hundreds of kilometres without feeling the affects of the road underneath you - even over bumpy country back roads and lumpy dirt sections.

The steering could be better; it’s a little bit vague and heavy on centre at higher pace, but at lower speeds it is light and amicable. Very easy to park despite its size, and easy to manoeuvre around town, too.

The engine builds pace with superb linearity, and it’s very quiet and refined as well. There is a tiny bit of turbo lag at lower speeds or from a standstill – but it is completely manageable and never feels like it’s sluggish at all. The 0-100km/h claim of 6.5 seconds seems achievable, too. 

The eight-speed automatic transmission was mostly very smart and well sorted - although in other VAG models with this engine family/eight-speed auto, the transmission never felt quite as busy at higher speeds. I noticed it shuffling between seventh and eighth gears more than I was expecting, given how much torque the engine has. It’s not annoying at all, and nor is it unrefined, and could well have something to do with attempting to save fuel rather than leaving it in top gear.

During night driving, the optional HD Matrix LED headlights were exceptional - among the best headlight technology that I’ve ever encountered. The ‘matrix’ technology means they can blank out oncoming traffic or cars in front of you while keeping the high-beam on in other areas. The auto headlights with auto high beam worked very well, too.

The plan was never to do a serious off road review, but I did do some driving on unsealed roads and found the Allroad to be excellent. 

Through slippery unsealed corners it exhibited excellent traction, though you can feel the weight of the car shifting from side to side when you pivot through corners. There was a touch of skittishness over mid-corner bumps, but again that could be more to do with the big wheels than anything else.

I came away thinking that if you had your eyes closed, you wouldn’t even know that you were on dirt or gravel. It really is an exceptional car across sealed and unsealed roads. 

The Sport Touring XT model is nice to drive. The best word to describe the on-road experience is ‘smooth’.

Power delivery is prompt and getting up to speed feels effortless. It's a great open roader but also feels spritely in the city.

The ride comfort is excellent and it’s only when you hit the highway that the wind noise starts to creep up, otherwise, the cabin is quiet and you can chat with back passengers without raising your voice.

The higher ride doesn’t translate to a bumpy suspension and while you’re aware of the road, you’re never bothered by it.

The steering is on the right side of firm for it to feel agile and competent no matter what you’re throwing at it. Visibility is also pretty good but the headrests in the back seat, when up, can hinder your rear-view vision.

The Outback sits at 4870mm long and 1875mm wide, so it fills out a car space but the higher ground clearance means you’re not worried about scraping on ramps and it’s relatively easy to park.

However, it feels cheeky to not have a 360-degree view camera system at this grade level. The reversing camera it comes with is sufficient, but you miss out on front parking sensors.

The Outback has a maximum five-star ANCAP safety rating from testing done in 2021 and features eight airbags which includes a front centre airbag.

It also scored highly across its individual assessment scores with ANCAP. It got 88 per cent for adult protection, 91 per cent for child protection, 84 per cent for vulnerable road users, and 96 per cent for its safety assist systems.

Standard safety equipment includes blind-spot monitoring, tyre pressure monitoring, LED daytime running lights, rear and forward collision warning, rear cross-traffic alert, lane departure alert, lane keeping aid, emergency lane keeping aid, emergency autonomous steering, lead vehicle start alert, traffic sign recognition, adaptive cruise control, reversing camera and front parking sensors.

The driver monitoring system has been improved from previous models and while still sensitive, it no longer chimes at you all the time, which is a welcomed change.

The Outback has two ISOFIX child seat mounts and three top-tether anchor points. The rear seat is wide enough to accommodate three child seats if they're not too large.

The auto emergency braking (AEB) has car, pedestrian, cyclist and back-over detection and is operational from 1.0 to 160km/h but it's usual to see this system operate from 5.0km/h, which is excellent.

Audi offers a three-year/unlimited kilometre warranty, which is as good as BMW, but not as good as Lexus (four years/100,000km) or Mercedes-Benz, Volvo and Genesis (five years/unlimited kilometres). It’s falling behind in the luxury sphere.

The company offers reasonably priced capped price ownership plans for maintenance. Purchasers can roll in the cost of either a three-year service plan ($2170) or a five-year plan ($3300). That covers off the usual service items due every 12 months/15,000km.

Roadside assist is included for the period of the new car warranty.

Subaru offers the Sport Touring XT model with a five-year/unlimited kilometre warranty but it’s becoming more common to see longer warranty periods being offered now.

You can pre-purchase a three- or five-year servicing program and the three-year program costs $1406.57 (average of $469).

The five-year option costs $2646.17 (average $529 per service) which is reasonable for the class.

Servicing intervals are good at every 12 months or 15,000km, whichever occurs first.
