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.
Lamborghini's Aventador S is the last living link to supercars of old. Wild-looking bedroom-poster material, gigantic anti-socially loud V12 that actually spits flame and the kind of performance that will rustle the jimmies of even a seasoned supercar driver.
It harks back to a time when supercars actually sucked, but it didn't matter because they were proof you had both the money and patience to nurse it into life and then wring its neck, because that was the only way it made any sense. While the Huracan is a thoroughly modern supercar, the Aventador is an unashamed, unabashed, hairy-chested, head-banging, rock ape.
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 Aventador isn't the best car you can buy for the money and truth be told, it isn't the best Lamborghini, which is a bit tough when you remember the only other car they make at the moment is the V10 Huracan. But it's all about the theatre as much as being a very capable supercar.
I'm not a Lamborghini fanboy, but I completely get the Aventador. It's a because-we-can car, just like the Murcielago, Diablo and Countach before it. But unlike those cars, it's thoroughly modern and with the upgrades introduced to the S, it's faster, harder and enormously entertaining.
As the last of a dying breed it delivers on everything a Lamborghini should - amazing looks, nutty price tag and an engine that excites not just driver and passenger but anyone with a heartbeat. It's by far the most charismatic car you can buy, no matter how many zeroes are on the cheque.
“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.
Asking if there's anything interesting about a Lamborghini design is kind of like asking if the sun is warm.
While there are some geese out there in the corners of the internet who think Audi has ruined Lamborghini styling, there is absolutely nothing shy about the Aventador. It's an incredible looking machine and, if I may say so, shouldn't be had in black because you miss a lot of the madder details.
This car is all about the experience.
It might look close to the deck in the photos, but however low you think it is, it's lower. The roofline barely makes it to the bottom of a Mazda CX-5's windows - you need your wits about you in this car because people just don't see you.
It is absolutely spectacular - people stop and point, one chap sprinted an easy 200 metres to take a photo of it in the Sydney CBD. Hello, if you're reading.
Inside is pretty tight indeed. It's amazing to think that a car 4.8 metres long (a Hyundai Santa Fe is 4.7 metres) struggles to contain two people over six feet tall. My six foot two photographer's head left an impression in the headlining. It's a tiny cabin. It's not a bad one though, it even has a cupholder on the rear bulkhead behind the seats.
The centre console is covered in Audi-based switchgear and is all the better for it, even if it is starting to look a bit old (those bits are from a pre-facelift B8 A4). The alloy gearshift paddles are fixed to the column and are brilliant to look at and touch, while the digital dashboard - which changes with the driving mode - is fantastic even if the reversing camera is awful.
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.
Yes, well. There's not a lot of space because a V12 is not just big all on its own, all the ancillaries to support it rob a lot of the remaining space. Having said that, there's room in the front for soft bags with a 180-litre front boot, space for two people inside, a cupholder and a glove box.
And the doors open up into the sky rather than out like a normal car's. Who cares if it's impractical, it's hardly something that's going to stop someone buying one.
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.
As with any Italian supercar, the price-to-feature ratio is rather higher than your average humdrum hatchback. A 'naked' Aventador S starts at a horse-spooking $789,425 and basically has no direct competition. Ferrari's F12 is front-mid engined and any other V12 is either a decidedly different Rolls Royce-type machine or super-expensive niche manufacturer (yes, niche compared to Lamborghini) like Pagani. They're a rare very breed, Lambo knows it, and here we are a sneeze-on-the-spec sheet away from $800,000.
So you have to keep two things in mind when rating a car's value for money at this level. The first is that there isn't any real rival in a pure sense, and if there was, it would be the same price and have the same spec. That's not excusing it, by the way, it's an explanation.
Anyway.
For your eight hundy you get 20-inch front wheels and 21-inch rears, climate control, cruise control, 7.0-inch screen (backed by an older version of Audi's MMI), four-speaker stereo with Bluetooth and USB, car cover, bi-xenon headlights, carbon ceramic brakes, electric seats, windows and mirrors, leather trim, sat nav, keyless entry and start, four-wheel steering, leather trim, digital dashboard, power folding and heated mirrors, active rear wing and active suspension.
The number of out-of-the-box options is staggering and if you're keen to really get on it, you can commission your own options when it comes to trim and paint and wheels. Let's just say that as far as the interior went, our car had almost $29,000 of Alcantara, steering wheel and yellow. The telemetry system, heated seats, some extra branding and front and reversing camera (uh-huh) added up to $24,000, the cameras almost half that total.
With all the bits and bobs, the test car we had was a sobering $910,825 before on-roads.
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.
The Aventador S is powered by Automobili Lamborghini's 6.5-litre V12. You know it's a V12 because there's a plate on top of the engine (which you can see through the optional glass cover) that says so, and handily, tells you the cylinder firing order. That's a neat touch.
Buried deep in the middle of the car, this monster engine develops an astonishing 544kW (30kW up on the standard Aventador) and 690Nm. Its dry sump means the engine sits lower in the car. The gearbox is slung across the back between the rear wheels - the rear pushrod suspension actually sits on top of and across the gearbox - and is apparently brand new.
The transmission is known as an ISR (Independent Shift Rod) and has seven forward speeds and still just the one clutch. Power goes through all four wheels to the road, but it's clear the rears get the lion's share.
The 0-100km/h time is the same as the standard car, which kind of tells you that 2.9 seconds is about as quick as you can go on road tyres when you don't have four electric motors with torque from zero rpm.
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.
Hilariously, the official figure is 16.9L/100km. I doubled it without trying. Simple as that. If you're buying this car thinking it will be easy on the juice, you're insane.
Cheeringly, Lambo has at least tried, the V12 going silent when you sit at the lights, the best thing being the way it bursts back into life when you lift off the brake.
If you have the time available, it takes 90 litres of premium unleaded to fill the tank.
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.
In Strada or Street mode, awful. Everything is slow and doughy, particularly the gearshift which goes looking for a gear like dog looking for a stick you didn't throw, but instead hid behind your back. The low-speed ride is nothing less than terrible, fidgeting over every single lump and bump and is only slightly more appealing than being dragged along behind.
The gearbox is really the worst bit about it. Automotive history is littered with cars that laboured along with a single clutch semi-auto: Alfa Romeo 156, BMW's E60 M5 and today the Citroen Cactus is stuck with just such a dud transmission.
Like that old M5, however, there's a trick to making the gearbox work for you - show absolutely no mercy.
Switch the selector up to Sport, get off the highway or major arterial road and head for the hills. Or better still, a clear race track. Then the Aventador goes from a pain in the rear to a glorious, roaring, completely unhinged and unhinging battle cruiser. This car is all about the experience, from the second you lay eyes on it to the moment you put it to bed.
This isn't an everyday supercar and it's absurd to think Lamborghini thinks it is.
First up, there's the obvious entry point with those wacky doors. While it's tricky to get in, if you're under six feet and reasonably mobile, stick your backside in, keep your head down and you're in. If you've been clever, you've specified the glass engine cover so you can see out the back but the huge wing mirrors are surprisingly effective.
Has someone thoughtlessly parked the car in a tight spot? No trouble, the four wheel steer makes the car absurdly manoeuvrable given its extravagant length and width.
As we've already established, it's not much fun at low speeds, waiting until about 70km/h before things start to make a bit more sense. This isn't an everyday supercar and it's absurd to think Lamborghini thinks it is. It just isn't.
The old Aventador was not the most capable of machines but made up for it with its overall belligerence. The new S takes that aggro and dials it up. When you move the drive mode to Sport you are basically unleashing hell. You can pretend to be super-masculine and switch to Corsa (race) mode, but it's all about getting the car straight and getting you around the track in the most efficient way possible. Sport is where it's at if you want to have fun.
The Aventador is about being seen, but not before you've been heard - from two postcodes away. It really is utterly glorious when you have a stretch of road to yourself. The V12 revs furiously to its 8400rpm redline and the wallop of the upshift is accompanied with a fantastic bark and a burst of blue flame. And these aren't the best bits.
Approach a corner, stomp on the colossal carbon ceramic brakes and the exhaust erupts in a combination of bangs and pops and growls that puts a smile on even the most hardened car-hater's face. The fact it steers into corners with just a demure roll of the wrist, aided and abetted by that funky four-wheel steering system. It's just brilliant, addictive and truth be told, it gets under your skin.
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 Aventador doesn't have an ANCAP safety rating but the carbon chassis also comes with four airbags, ABS, stability and traction controls.
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.
In an unexpected twist, you'll get a three-year/100,000km warranty and the option to increase to four years ($11,600!) or five years ($22,200!)(!). Having recovered from typing that, given the cost of something going wrong, that's probably money well-spent.
