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.
Don’t let people talk you into buying a tiny car just because you live in the city. That’s what I’ve learnt from being a car reviewer and living about eight kilometres from the CBD.
Yes, car spaces are small, or almost non existent, but the people that live there are as full-sized as people elsewhere and they often carry around just as much gear. What you need is a big, little car and the Renault Kadjar is that – a small SUV which is actually bigger than most.
The Kadjar is also French, and that’s appealing to us city folk because even though there are millions of us living in one square metre we like to think of ourselves as different, as individuals, cosmopolitan, metropolitan.
So the Kadjar looks perfect then, right?
Well, it’s good yes… in some ways, but after reading this you might prefer its Japanese cousin, the Nissan Qashqai. Let me explain...
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 Renault Kadjar Intens ticks a lot of the urban boxes. It’s small, which is good for navigating narrow city streets and parking in tight spaces, but it’s also spacious and practical. The Kadjar is fuel efficient for a four-cylinder petrol engine and it has that sophisticated French styling.
The Intens is expensive, though, and unless you absolutely have to have leather seats, a glass roof, and the Bose stereo I’d go for the mid-range Zen grade and save yourself $5K but still have all the same safety tech. That said the Intens has auto parking as standard which is a nice convenience for the city.
Safety could be better. The AEB system doesn’t have pedestrian and cyclist detection, rear cross traffic alert, or reverse emergency braking.
Finally, the dual-clutch automatic and 1.3-litre turbo-petrol engine while a fuel efficient combination, isn’t all that easy to live with and can make driving a less-than-smooth experience. The Nissan Qashqai’s combination of CVT auto and four-cylinder naturally aspirated engine is better suited to the urban jungle - something to think about there.
Now the scores, the Kadjar Intens gets the same mark for daily driving and its urban talents – it could be smoother to drive, but there’s still lots to like.
“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.
People talk about French design being good. Well if you want to see just how good take a look at the Nissan Qashqai, because the Kadjar is fundamentally the same SUV with Renault’s design spin applied.
Yep, as I mentioned about 15 seconds ago, Renault and Nissan are part of an alliance that allows them to share the same cars, but each brand has room to ‘make it their own’ with styling that delivers a very different look, inside and out.
Now, the Qashqai is not an ugly car, but I think the Kadjar is more stylish and premium looking in the same way the larger Renault Koleos SUV is gorgeous compared to the relatively straight-laced Nissan X-Trail it’s based on.
There’s no doubt the Kadjar is a Renault thanks to the giant diamond logo on the plunging grille. I like the way the front bumper rises up into the bonnet like it’s all one piece, but I’m not completely sold on the rear of the car which looks a bit like its shirt is tucked into the back of its pants, which makes no sense unless you look at the images.
Still, the tail-lights have a prestige feel and the Kadjar model name spelled out across the tailgate is a confident statement, also adopted recently by other brands such as Volkswagen (T-Cross) and Ford (Puma).
Telling the Intens apart from the other two grades is fairly easy, it has 19-inch wheels (the others have 17-inch rims), there’s the enormous glass roof, and it also has a chrome effect on the front and rear bumpers, side skirts, and around the fog lights. It’s a more premium look.
That higher-end feel goes into the cabin as well with the Intens’ black leather upholstery and colourful ambient lighting. The touchscreen is tiny, though, and there isn’t a great deal inside that you don’t get in the entry-grade Kadjar’s cabin, which is also almost as stylish.
The Kadjar is classified as a small SUV, which means nothing really when it comes to wondering if it’s going to fit in your garage or in the tiny parking spaces we’re faced with in the city.
So, I’ve mapped it out for you. The Kadjar’s dimensions are, 4449mm long, 2058 mm across (including the wing mirrors), and 1612mm tall.
Another interesting thing – each B-pillar is adorned with a little French flag. I’m not sure if they're a sign of Gallic national pride or to remind everybody that meets the Kadjar that Renaults are French.
Either way, you don’t see this type of thing on other cars and for many buyers the appeal of a Renault is having a car that’s not like everybody else’s.
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 Kadjar is a big-small SUV, in that it’s longer than many in the same segment at 4.4m with a wheelbase of more than 2.6m, which means more space inside for people and their stuff.
That said, don’t expect limousine legroom, but at 191cm (6'3") tall, I can sit behind my driving position with my knees only just touching the front seat back, which is pretty darn good for a small SUV.
Making life a bit more comfortable back there, too, are directional air vents, two USB charging ports and a 12V power outlet. There are another two USB ports and a 12V up front, too.
Cabin storage is okay. The door pockets in the back are big enough for a 500ml bottle, while there are larger ones in the front, along with two cupholders and another circular hole, which looks like it’s for coins, if anybody still uses those?
The centre console bin is pretty decent in size and so too is the boot which has a cargo capacity of 408 litres with all seats up and 1478 litres with the second row folded flat.
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.
The Intens is the highest grade of Kadjar you can buy and has a list price of $37,990. As a point of reference, the entry-grade Kadjar with an automatic transmission is $29,990. So, what are you getting for an extra $8K?
Well, the entry-level Kadjar comes with a 7.0-inch touchscreen with Apple CarPlay and Android Auto, cloth seats, dual-zone climate control, privacy glass and 17-inch alloy wheels. The Intens gets 19-inch alloys, leather seats (heated up front), a seven-speaker Bose sound system, leather steering wheel, panoramic sunroof, as well as LED headlights and fog lights.
The Intens also comes standard with auto parking, and even the most determined DIY parkers will appreciate that in the city.
The Intens also has more advanced safety equipment than the entry-grade, although the same tech also comes on the mid-spec Zen for $32,990.
You may already know this, but the Kadjar and the Nissan Qashqai are essentially the same car. Renault and Nissan have an alliance which lets them share technology and as well as entire models.
So, you might want to compare the Kadjar Intens to a Qashqai Ti which lists for $38,790. Other models to check are the Mitsubishi ASX and Toyota C-HR.
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.
While the Renault Kadjar and Nissan Qashqai are essentially the same car, they don’t share the same powertrain. The Kadjar has a smaller but more powerful engine – a 1.3-litre turbo-petrol four-cylinder making 117kW/260Nm.
Shifting gears is a seven-speed dual-clutch auto. There’s no manual available, and all Kadjars are front-wheel drive.
Frankly, the Qashqai four cylinder with less grunt and CVT are a smoother combination. The dual-clutch auto and turbo lag means power delivery and acceleration are delayed, while low-speed gear shifts can be jerky.
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.
Renault says after a combination of open and urban roads the Kadjar will have used 6.3L/100km. In my own testing I measured 6.5L/100km at the fuel pump. That’s outstanding.
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.
Renault’s Kadjar may be a better-looking version of Nissan’s Qashqai, but it doesn’t drive as well. This comes down to the engine and transmission Renault has gone with.
There’s turbo lag with that small four-cylinder and this delay is made more pronounced by a dual-clutch transmission that causes the vehicle to lurch during shifts.
This type of shemozzle is not uncommon, the Ford Puma and Nissan Juke behave in the same way with their similar powertrains.
There’s nothing wrong with them, it’s just that for a car that’s probably going to spend its life mainly in the city, the Kadjar won’t provide the smoothest driving experience.
The Qashqai has a CVT automatic and while these transmission aren’t as sporty feeling as a dual-clutch, they’re smooth and good for easy city driving.
The Kadjar does have a comfortable ride and good handling, so if you’re able to get used to the antics of the engine and transmission there’s more to like than not about the way this Renault drives.
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.
The Kadjar hasn’t been given an ANCAP safety rating, but it did score the maximum five stars when tested by its European equivalent Euro NCAP in 2015.
But beware, the Kadjar isn’t equipped with much in the way of advanced safety equipment. Yes, there is AEB on all grades, while the mid-spec Zen and top-of-the-range Intens come with blind spot monitoring and lane departure warning. But that’s about it. No lane keeping assist, or rear cross traffic alert, or adaptive cruise.
There are front and rear parking sensors, which are almost vital in the city, and a reversing camera.
It’s for this reason the score here is so low – charging $38K and not having anywhere near the level of safety tech on a new car that costs much less is disappointing.
For child seats there are three top tether anchor points across the second row and two ISOFIX points.
Under the boot floor is a space saver spare wheel.
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 Kadjar is covered by Renault’s five-year/unlimited kilometre warranty.
Service intervals are every 12 months or 30,000km and capped at $399 for the first three services, followed by $789 for the fourth then back to $399.
There’s also up to five years roadside assistance, if you service your Kadjar with Renault.
