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 is a brand built on madness, excess and eye-searing design. Its cars don’t have to make sense, and indeed its owners probably prefer it if they don’t - they have other vehicles to use for the real world.
So, the existence of the new Lamborghini Huracan Sterrato, the world’s first 'All-terrain Supercar', a V10-engined mad machine built to drive sideways at high speed on dirt, should not come as a surprise.
And yet it really does, because there’s never been anything like it before (yes, Porsche has built the 911 Dakar, but it’s more of a sand-dune-climbing, desert-crossing motorsport tribute), for the very good reason that no one ever considered it would be a good idea.
It also sounds just a touch intimidating, the kind of driving experience that would require pro rally driver skills to survive, so it was with some trepidation that we headed to Palm Springs, USA, to test out the new Huracan Sterrato.
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.
Not just a spectacularly stupid idea made real, the Lamborghini Sterrato is by far the best, or at least most hilarious, of the many Huracan variants the company has produced.
It makes you feel like a hero, even when you’re going sideways on dirt like a nutter. It could just be my new favourite supercar.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
“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.
Oh yes, it’s pretty interesting, all right, because it breaks new dusty ground for Lamborghini, and its Huracan in particular.
To cope with its intended use, the Sterrato has been raised 44mm higher than the ground-hugging normal version and it’s also had giant, bolt-on style guards attached to make it look a bit wilder.
Also quite noticeable is the huge roof scoop - which renders rear vision from the driver’s seat a complete zero, they may as well throw the mirror away - which has to be there to help the V10 engine breathe.
The side air intakes through which air usually gets to the mid-mounted power plant have been blocked up, because they would have sucked in too much dirt and gravel.
I’m happy to report the silly looking rally style headlights stuck to the Huracan’s shark nose are optional, although again, no doubt every buyer has gone for them, because they stand out in a crowd.
The Huracan Sterrato has no problem doing that on its own, of course, because it already looks extremely aggressive, and its knobbly, all-terrain tyres finish off that style flourish.
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.
Next question, please. You don’t get cupholders, there’s not really anywhere to put your phone and the cabin generally feels as roomy as a phone box that’s been through the wash and shrunk quite badly.
There’s a frunk that can barely hold two small backpacks and that’s about it. If you want practical space, buy an Urus. The Huracan Sterrato is not a practical car, but that’s not part of its design brief.
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.
Well, considering every Lamborghini Huracan Sterrato will almost certainly go up in value and become a collector’s item you’d have to consider them good value, at least in investment terms.
On the other hand, any car with a price tag of $503,949, before on-road costs, sits somewhat adjacent to the word “value”.
That large number has not put enthusiasts off, however, with all 1499 of the limited-run Sterrato Huracans already sold, and a long list of people with their names down hoping that someone gets scared and changes their mind, apparently.
Our vehicle came with two built-in cameras, which you could operate through the touchscreen to record Tik Tok-length videos of your driving.
This is almost certainly a cost option, but no one could tell us exactly, and all of the cars are already sold, no doubt to people who ticked every single option box.
Oh, and you do get aluminium floor mats. Nice.
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 Sterrato is powered by a Lamborghini engine that’s on its way into the history books, a 5.2-litre V10 that will die with this, the last variant of the Huracan.
Its replacement will be powered by a V8 hybrid, which will no doubt be more powerful but simply will not sound as amazing.
The version in the Sterrato has been detuned slightly, partly because of the breathing issues - you just can’t get as much air into an engine when it’s driving through its own self-propelled dust storm - and because of its all-terrain tyres, the first ever to be speed rated to 260km/h.
It still makes an impressive, and very loud, 449kW (602hp) and 560Nm, however. I’d describe it as “more than enough”.
That monster engine is matched with a seven-speed dual-clutch automatic and a very, very clever all-wheel drive system.
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.
So, Lamborghini claims the Huracan Sterrato will deliver a fuel "economy" figure of 14.9 litres per 100km, which seems like a lot, until you consider it probably won't get anywhere near that, if you drive it the way you're supposed to, particularly foot flat and wheels spinning on dirt.
Again, fuel economy is not a core value for this car, nor its buyers.
An 80-litre tank means a theoretical range of around 480km.
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.
I could give you the short version of what it was like to drive the Lamborghini Huracan Sterrato at speed on a specially prepared dirt race track, which would be to say that I have never, ever had so much fun in a car, but that would be selling it short.
While the Sterrato is clearly built to do one insensible thing brilliantly, while somehow not imperilling the life of its driver, what is most incredible about it is how good it is at everything else, as well.
To create this Huracan, Lamborghini had to increase the ride height significantly, soften up the suspension and increase its amount of travel.
It also had to ask Bridgestone nicely to produce a tyre unlike anything the world has ever seen, an all-terrain tread capable of dealing with dirt and gravel and yet also grippy enough to be used on a sealed race track, or to carve up your favourite mountain pass.
It also had to be capable of being speed rated to 260km/h, or about 100km/h faster than any all-terrain tyre Bridgestone has ever produced before.
Looking at the unique Dueler All-Terrain AT002s, with their chunky tread, you would assume that the Sterrato is going to be noisy, slippery and possibly a little rough on public roads, but that’s not the case at all.
This Huracan rides more smoothly - largely thanks to those suspension tweaks - and more quietly than its forebears, and it’s actually more practical around town as well, thanks to the ride height. So, no more flinching at speed bumps.
The tyres also provide proper supercar levels of grip on public roads, even those dusted with a bit of desert sand.
There’s a bit of squirm at the rear and under hard braking, but overall the experience is typically Lamborghini Huracan wonderful, all playing out to a soundtrack that is beyond beautiful from that howling V10.
The first part of our track experience at the Chuckwallah Raceway was also familiarly fantastic, the Huracan ripping around the sealed track at astonishing speed; it certainly doesn’t feel detuned.
Lamborghini had gone to the trouble of mirroring the sealed circuit with a specially constructed dirt track in the infield, so that 50 per cent of our lap would be spent sideways in ankle deep, dust, sand and rocks, much of it through long, long bends, with the occasional chicane set up specially for Scando flicking action.
Now, I am not, by any means, an expert at drifting, nor an accomplished rally driver, so I was, to put it mildly, shit scared of getting this half-million-dollar, limited-edition, 449kW monster on to the dirt section.
I feared I would spin around, or flip upside down, or find some other way to embarrass myself, but what happened when I got there was beyond inexplicable, and beyond joy.
This car is so clever, so easy to drive, so beautifully balanced, that it can turn a total newb into Colin McRae. His name comes to me because the whole experience reminded me of driving a rallying video game, it felt unreal, and yet overpoweringly visceral at the same time.
I could start a drift with the slightest flex of the throttle, then balance the car as it pivoted around a bend before nailing the throttle and haring off to the next fantastic drifting opportunity.
When we got back on the sealed stuff, the car would shake like mad, at 200km/h, as the dust attempted to get its way out of the wheels, but that just added to the excitement.
The secret wasn’t that I’d somehow become a better driver, it was what Lamborghini engineers call, accurately, “the hero maker”.
It’s a software and hardware package called LDVI, or 'Lamborghini Dinamica Veicolo Integrata', which, when you put the Sterrato in 'Rally' mode, uses many sensors combined with torque vectoring and selective braking to keep you going where you want to go, with minimal intervention.
Or at least minimal intervention that you can feel, which makes you feel like a hero.
I kind of understand how it works, but I totally relate to how it makes you feel. Like a genius. And you’d pay $500K for that, surely?
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.
In a V10-engined supercar you’re meant to drive on dirt? You’ve come to the wrong place.
Okay, so there’s no crash rating, and there won’t be, but you do get AEB, driver, passenger, and side airbags along with knee airbags as well as front and rear-specific collapsible areas, reinforcement bars in the doors. Oh, and Electronic Stability Control.
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 Huracan Sterrato comes with a Lamborghini warranty good for three years with unlimited kilometres.
It also comes with 24/7 roadside assist for an unspecified amount of time. It is also offered with pre-paid scheduled maintenance service for three or five years.
