What's the difference?
When I say this is a rare review, I’m talking about the kind of rare that means you can’t even buy the car you’re reading about.
The 2026 Audi RS6 Avant GT you’re looking at in the pictures around this story is number 248 of 660. That’s six-hundred and sixty worldwide.
In Australia, there are only 22 RS6 GTs, and they’re all sold - at exorbitant prices, mind you, but we’ll get to that.
The RS6 GT is essentially a production version of the Audi RS6 GTO concept, built in 2020 and inspired by the Audi 90 quattro IMSA GTO race car, which means the RS6 GT carries a lot of ‘90 GTO’ in the way it looks. More on that shortly.
Aside from its extremely limited availability and its design package, there are some mechanical changes to increase the appeal of the RS6 GT, though whether any of its owners will put the on-road (or on-track) ability of this special wagon from Ingolstadt to the test remains to be seen.
A couple of days to live with one of the few RS6 GTs in Australia should reveal how special this car feels, and result in at least one example of the rarity being driven good and proper.
A wagon and not an SUV, eh? Respect. You see, when most people now think of a new car they think of an SUV, especially when they want something with a bit of cargo space. But not you.
And for thinking outside the box you’ll be rewarded with something that’s better to drive than most SUVs – like the Hyundai i40 Tourer in the Active grade and a diesel engine we’ve road tested here.
So, what are the strengths and weaknesses of this Korean wagon, and should you wait or buy it now? Read on to find out.
You’ll notice a number out of 10 on this review, you should ignore it.
Not only is it irrelevant because you can’t buy one, but the RS6 Avant GT isn’t a ‘brain’ car, it’s a ‘heart’ car. As much as a five-seat wagon can be, anyway.
Whether you think it’s overkill, overpriced, or overhyped, the GT is a celebration of a car that’s become such an icon for petrolheads. It’s also probably a marker for the end of an era, because we don’t see many V8 family cars getting about anymore.
Well done to Audi, the accounting team in particular, and if anyone who owns an Avant GT is willing to let me have another drive, my in-box is open.
Or I’ll just keep an eye out.
The i40 Tourer in the Active grade is great to drive, it’s practical, and should be low-cost to run. But you can bet the new version, due to arrive soon, will be, too. If you can wait, it's a safe bet the new i40 Tourer will have an updated look, improved safety equipment and retain all the good points of the previous model.
“It looks like a toy car you’d get in a Kinder Surprise” was the first comment from my housemate upon seeing the $400K collector's item on wheels.
Harsh, but to anyone unfamiliar with the Audi 90 quattro IMSA GTO racer, there’s arguably too much going on with the RS6 Avant GT.
The red, grey and black decals, the chunky white 22-inch wheels, the flared and vented front fenders and the wing over the rear window… all of it is a lot to take in, but it’s very faithful to the IMSA car.
As pictured, the 90 quattro IMSA has the red around the bottom lip of the car, on the bonnet, and even its rear wind, the same as the red on the rear of the Avant GT.
Some of the black at the front of the car, where the bonnet and fenders are, is just exposed carbon-fibre rather than a black decal.
Short of the sponsors and racing numbers, the Avant GT does a fabulous job of paying homage to the 1989 race car. It just means you’re going to be the centre of attention anywhere you drive. Or park.
On that note, an alternative paint and graphic scheme in 'Mythos Black' (this car is 'Arkona White') was available to customers and is decidedly more ‘under the radar’. You have to wonder, though, if you opted for the subtle version of a car that pays homage to a fire-breathing IMSA car, would you feel like you took the coward's option?
Besides, you’re either keeping this car in some kind of temperature-controlled bubble, or (hopefully) spending most of your time around it in the driver’s seat. From there, you don’t have to grapple with the question of garishness.
The interior is, while elevated past standard RS6 vibes, a lot more subtle. Dark materials of microfibre, carbon, leather and the smudge-prone piano black (an Audi favourite) are joined by a relatively restrained serving of red in the contrast stitching and seatbelts.
The i40 wagon looks good, I even caught myself doing that admiring 'look back' thing you do when you walk away from your car. Thing is, the current i40 has the ‘old’ Hyundai styling that dates it compared to the new i30, Sonata and Kona, which reflect the brand’s latest look.
This brings me to something you should really know – the newer, updated i40 will arrive in Australia soon, and it will be more in line with Hyundai’s current design approach.
The i40 is also up against some hot-looking rivals. The Mondeo is gorgeous, the Passat is stately, and the Commodore also looks stunning. To be honest the i40 is the least attractive of that lot form where I’m looking. It’s also about the same size as that trio at 4775mm long, 1815mm wide and 1470mm in height.
My mum would call the interior of the i40 Active smart looking, but she doesn’t mean tech-smart, more school dance smart, and if she ever said that before you went to a school dance you’d get changed immediately.
Yes, it looks smart in a tidy, stylish way, but that tiny screen, cloth seats and ordinary plastics lower the tone compared to the Premium's more 'premium' interior.
You’ve bought a $400K collectible sports car capable of effortlessly deleting kilometres of highway with your family and enough luggage for a week. Usually a special edition driver's car at this price point is doing well if it has a place to put a phone and a water bottle, let alone phones and water bottles for four people - five if you really need.
Yes, in the performance car world, the Audi RS6 Avant has long been king of the convenience game and the GT holds onto that.
The seating position and ergonomics remains comfortable, the driver’s seat being manually adjustable means it can sit even lower, there’s decent storage in the door cards, cupholders are able to be hidden, the phone charger is under the armrest, there’s a spot for small items like keys, change or glasses and the rear seats have mostly the same alongside their own individual climate controls and heated seats.
Behind those, a 548-litre boot puts most performance cars to shame, but its 1658L space when the rear seats are folded down is unbelievable for something that you’d want to take to a race circuit.
The i40 wagon nails the practicality category. Storage space is excellent with a deep, wide console bin under the centre armrest, and there’s another big well in front of the gear shifter.
There are large pockets in all the doors with bottle holders, two cupholders up front and another two in the fold-down rear armrest, plus another storage area in there, too.
The i40 Tourer’s 506 litre cargo capacity is good, but can’t beat the Passat’s 650 litres, while it matches the Mazda6 wagon’s boot space.
Rear legroom borders on limo territory and even at 191cm I can sit behind my driving position with about 50mm of space between my knees and the seat back. Headroom back there is also extremely generous.
The rear doors open wide, making for an easy exit or entry, too.
I’ve been told I’m not allowed to swear in CarsGuide reviews, so add your own expletive when I say, at $399,000, before on-road costs, the RS6 GT is expensive.
A ‘standard’ Audi RS6 Avant Performance costs $252,600, so you would really, really hope that warm feeling you get from owning one of only 22 GTs in the country is worth around $146,400. It’s very hard to imagine the physical changes to the car amount to that much money.
Of course, there’s plenty of kit in the RS6, anyway. But unique to the Avant GT is a carbon bonnet, carbon wing mirrors and carbon front fenders, a restyled spoiler, tailgate, and rear diffuser, 22-inch Audi Sport six-arm ‘Avus’-inspired alloy wheels (in white or black), RS ceramic brakes and black badging.
Inside, there are RS front bucket seats trimmed in leather, synthetic suede and carbon, contrast stitching in red, red seatbelts, black synthetic leather along the dashboard with open-pore carbon, rear window sunshades and a Bang & Olufsen 3D sound system from the 'Sensory Package' as standard.
There’s also ‘RS6 GT’ scuff plates, floor mats, puddle lighting and the individual number for each of the 660 cars on the centre console.
There’s also manually adjustable coil-over suspension and a GT-specifically-tuned quattro sport differential.
It’s cool, but is it an extra $146K cool?
For the price, you’re almost in Ferrari territory, or you’re ticking some options boxes on your Porsche 911 Carrera T. Suppose neither of those can comfortably take a family of four on a holiday to the snow and even feel safe driving on icy roads, though.
It does happen to be about the same price as the Mercedes-AMG GT63 S 4 Door, though whether that looks as good as the RS6 is debatable.
There are only two grades in the i40 range - 'Active' and 'Premium'. And when it comes to engines you again have two choices - petrol or diesel. The latter adding $2600 to the price.
If you’re looking for the most affordable way into an i40 wagon go for the Active. Listing at a base price of $35,690, 'our' i40 Active Tourer diesel had one option – 'Ocean View' metallic paint, adding an extra $595.
The Active grade costs $9160 less than Premium, and as much as I’d like to say that top-spec car is pretty much the same, with some shiny bits of door trim added, I’d be lying.
The Active really does miss out on some decent stuff – the screen is the smallest I’ve seen since I wore a digital watch, at 4.3-inch (the Premium has a 7.0-inch), there’s air-con but not climate control, there’s keyless entry but not a proximity key or push button start.
The Active doesn’t get a power tailgate with a handsfree function like the Premium, or tinted rear glass, or a digital speedo, or a panoramic sunroof, or a power adjustable driver’s seat, or heated seats, all of which are standard on the Premium grade.
Yup, the Active may be as base grade as you can get but it still comes with paddles shifters, LED daytime running lights, an electric handbrake with auto hold function, front and rear parking sensors, cloth seats and 16-inch alloy wheels.
A list price nudging $36K may seem high, but don’t’ forget you’re paying more for the diesel engine. There’s good reason to spend the extra on the diesel, too – which I’ll explain below.
The i40 Active Tourer diesel undercuts the $39,040 Ford Mondeo Ambiente diesel wagon, while the Volkswagen Passat 140TDI wagon only comes in the mid-spec Highline grade for $49,990 (and is a bit ‘next level’ by comparison), while the Mazda6 wagon in Touring spec with diesel engine is $41,440.
Other rivals? Yes, the new Holden Commodore Sportwagon diesel is $38,890. So, compared to its rivals the i40 Active Tourer is a bit of a bargain.
Audi’s venerable 4.0-litre, twin-turbo V8 engine remains at the heart of the RS6, though in the GT there’s no more power than the RS6 Avant Performance.
That means 463kW of power and 850Nm of torque delivered to all four wheels via an eight-speed torque converter automatic and Audi’s ‘quattro’ all-wheel drive system, making the RS6 Avant GT capable of a 3.3-second sprint to 100km/h, according to Audi. Top speed is a blistering 305km/h.
All this in a car I took to Coles.
This is another area in which our test car impressed with its 1.7-litre four-cylinder turbo-diesel and seven-speed dual clutch auto transmission.
At 104kW, it may be less powerful than the petrol (121kW) but its 340Nm of torque gave it the shove to accelerate impressively from 1750rpm (idle is 800rpm).
The engine and dual-clutch combination performs beautifully; smooth even at low speed in traffic, and shifting down intuitively to make best use of engine braking.
Do you care about this section of the review if you’ve bought one? Surely not.
Anyway, Audi claims 11.8L/100km in terms of fuel consumption and you’d better believe it’s 98 RON minimum.
It’s got a 72-litre fuel tank, which was depleted rather rapidly on test. While driving conditions weren’t ‘fair’ in terms of the test given the content demands of a short-term loan, there’s probably a realistic figure somewhere between the claim and the 17.9L/100km I achieved over a few days.
Hyundai will tell you the i40 Tourer diesel will get 5.1L/100km over a combination of open and urban roads. The trip computer in our test car said it was averaging 7.4L/100km. Still, that’s not bad mileage.
There’s something unfortunate about how good the Audi RS6 Avant GT is from behind the wheel. That’s knowing how few people will properly get to enjoy it.
Not just because only 660 were built, but also because the majority of those 660 owners will be too worried about how much they’ve just spent on an automotive rarity to properly take it for a burn on a road, or even a track.
The RS6 was always an icon of Germany's penchant for subtle-looking cars that just happen to be capable of embarrassing much more brash vehicles, but the GT does away with the pretence and sharpens its teeth a little.
The specifically tuned rear differential makes for a more rear-biased driving experience in Dynamic mode, which means more agile cornering and a more natural balance compared to the way the RS6 sometimes feels - like a family wagon.
Its rival, the BMW M5 Touring, can go full rear-drive, but the Audi doesn’t need that as an option. It feels more capable and composed; ready to obey commands without fuss. A set of Continental SportContact 7 tyres (285/30) help there on the grip front.
The suspension underneath, adjustable coil-overs with three settings, is unique to the GT and lowers the ride height by 10 millimeters. It’s stiffer, 30 per cent at the front and 80 at the rear, and you notice it.
There’s more control and much less body roll, but the trade-off is the RS6 Avant GT is a little less comfortable on Australia’s particularly rough roads. Its 22-inch wheels don’t help.
It’s not, however, crashy or rattly. The suspension still does a fine job of stopping the driver being jostled around, but there’s a decidedly firmer response to the surface underneath. Again, still very composed.
With the new suspension, steering the GT feels easier than memory would suggest and the baseline was already good. There’s no unnecessary weight, but there’s still decent feedback from the front wheels and accuracy is bang-on.
Throttle adjustment in the corners, too, is easier with the rear differential, and it means anyone who still had reservations about Audi and understeer can be proven wrong.
The drivetrain remains unchanged from the Performance, which is a good thing. The effortless acceleration, even in the more aggressive 'Dynamic' setting with the transmission set to 'Sport' is smooth but seemingly unending.
Fortunately, the 4.0-litre V8 under the carbon bonnet sounds delightfully burbly, so getting to the speed limit or overtaking is a little treat every time. While the steering wheel paddles are there if you really need to drive in anger, the eight-speed is fine left to its own devices.
A 2.0-tonne family wagon with a V8 up front, easy communicative steering, and sporty suspension that settles well over bumps but allows enthusiastic corner attacks?
The RS6 Avant GT is in limited company.
A comfortable ride, impressive handling for the class, and a great engine and transmission mean the i40 Active Tourer diesel is engaging and enjoyable to drive.
The driving position is excellent, the seats are large but supportive, and the pedal feel is spot on. The i40 Tourer is way better to drive than it needs to be and would embarrass some cars from more prestigious brands.
It’s not all perfect: the cabin could be better insulated with wind noise obvious at 90km/h and tyre rumble intruding on course chip roads; visibility is hampered by those slanted A-pillars and the reversing camera image is next to useless thanks to the business card-sized screen in the Active.
There’s no current rating from ANCAP for the A6 in general, let alone this specific RS6, but there’s a decent suite of safety equipment and tech to keep you worry-free in the GT.
Eight airbags and more than 30 driver assistance systems from the RS6 are of course present in the GT, including adaptive cruise control, lane-keep and warning, emergency brake assist and cross-traffic alert.
Audi’s also got surround view cameras for parking, which also includes warnings for approaching vehicles or objects, plus there are preemptive measures the car can take in an impact like tightening the seatbelts or braking to avoid a second collision.
The second row also has three top tethers and ISOFIX anchor points on the outboard seats for mounting child seats.
Hyundai’s website says the i40 Tourer scores the maximum five-star ANCAP rating. That’s true, but a bit sneaky because that ranking was given to the car back in 2013, and a lot has changed in terms of safety equipment in five years.
AEB, for example, is becoming common. So is rear cross traffic alert and blind spot warning, along with adaptive cruise control. You can’t get any of this advanced safety equipment on the current i40, not even the top-spec Premium.
Don’t get me wrong, the i40 is extremely safe with its suite of airbags, plus traction and stability controls - it’s just that the bar for safety has been raised higher.
The new i40 is expected to come armed with more up-to-date safety equipment.
If you’re fitting child seats you’ll find two ISOFIX mounts and three top tether anchor points across the rear row. It’s great to see a full-sized spare wheel under the boot floor, too.
Audi’s five-year/unlimited kilometre warranty is below industry par, though most premium brands are in the same boat.
Twelve years of bodywork warranty against corrosion is also included, as is a five-year run of free Audi roadside assistance.
Five-year service plans can be purchased, or customers can buy back-to-back two-year extensions for the warranty, servicing and roadside assistance.
The i40 Tourer is covered by Hyundai’s five-year/unlimited-kilometre warranty. Servicing is recommended every 15,000km/12months at a capped price of $339. A servicing plan is also available for three years ($777), four years ($1136), and five years ($1395).
