Audi RS Q8 vs Kia Sportage

What's the difference?

The Audi RS Q8 Performance is a lot - of everything. It offers lots of power, lots of performance, lots of space and lots of luxury. But it’s also a lot of money, and at more than $250k it’s not going to be on everyone’s shopping list. It’s a very niche proposition for a small group of buyers. For those select few, those who want a lot of everything and who crave the ultimate of whatever product they’re buying, then the RS Q8 Performance is going to be a very tempting proposition - even if they never set any lap record in it.

The Sportage still feels like a super solid offering in its segment, plus the addition of more hybrid options is only going to help.

It does feel a little under-specced in the lower grades, though, considering the everything-and-the-kitchen-sink approach taken by its Chinese rivals.

I feel like I should almost whisper this bit, given it's a dirty word at the moment, but that diesel engine, it's a real peach, and if I wasn't afraid of being run out of Sydney's inner west with pitchforks, that's probably the one I'd be choosing.

We don’t refer to ‘facelifted’ cars for no reason, the RS Q8 Performance has a number of visual changes.

These include a new Audi ‘singleframe grille’ and new front bumper design, with a new Matt Carbon trim package available to highlight that.

There’s also a new rear bumper design as well as new digital daytime running lights at the front and digital OLED lights at the rear.

The unique forged alloy wheels are another design change, but also bring a functional element. Measuring 23 inches they do a good job of filling out the wheel arches and give the RS Q8 Performance a purposeful stance and good proportions. But they are also 5kg lighter per wheel than the 22-inch rims on the RS Q8, saving unsprung weight to help the ride and handling.

Inside, Audi hasn’t made any dramatic changes to the design, which is fine because the brand does some of the best cabins on the market in terms of look and feel.

What is new is an aluminium inlay and an optional RS interior design package which provides a unique finish to the seats, with contrasting stitching, for an additional $4100.

All new Sportage models feature a redesigned front and rear end, but they actually have a slightly different look. There's one look for the cheaper models and then one for the top-spec cars, the SX+ and GT-Line.

The changes aren't overwhelming, though. There are fog lights in the more expensive models, but also just more use of black edging, as opposed to the silver edging that frames the bottom of the grille and rear end in the cheaper cars.

Either way, I still really like the way the Sportage has come together. The front end looks bold and powerful, mostly because of the vertically stacked headlights and and the DRLs that really frame the front end, but they've also done a good job of making a fairly big and spacious SUV feel small and not too imposing.

Now, inside the top-spec cars it’s very modern Kia, with a big twin-screen setup, and the dual-function bar beneath them that handles things like climate control, but also mapping and media and those kinds of functions. The cheaper models also get the same look, but swap the second 12.3-inch screen for a smaller driver display.

It means you don't have to dig through the screen for everything, which is always a nice touch. And I also like some of the materials used in the GT-Line, too, like the synthetic wood grain that’s actually nice to touch.

But there are a couple of key downsides. Not quite so much in the top-spec cars, but in the cheaper versions. I hate those constant reminders that you didn't spring for a more expensive model, and there are plenty of those in the lower-spec cars.

In the more expensive models, there are buttons alongside the gearshift, but in the cheaper cars, those buttons are still there, just blacked out and inactive. And even the cutout for the head-up display still exists in the cheaper cars, but of course, there's no head-up display.

All of that combined with some hard and scratchy plastics front and back makes you really want to dig deep for a more expensive Sportage.

While it’s easy to get swept up in the power and speed of the RS Q8 Performance, it’s important to remember that it’s an SUV and it needs to offer ‘utility’ as well as ‘sports’. 

With that in mind, the front seat occupants are well looked after with supportive and comfortable sports seats, with a good amount of small item storage spaces. 

The rear seats are surprisingly comfortable, despite the sloping roofline of this ‘coupe-style’ SUV. Audi has cut recesses into the ceiling to create more headroom, so it will be fine for anyone under six-foot tall. Despite there being five seat belts, this is realistically more of a four-seater for adults, although three smaller kids could squeeze across the back.

There’s also a pair of cupholders, two USB-C ports, a 12-volt outlet and your own climate controls for the rear passengers.

As for the boot, again it loses some volume because it’s not a wagon-style SUV, but there’s still a decent, square floor space with a claimed 605 litres of capacity.

So, overall the Q8 obviously isn’t the most practical version of an SUV, but it does well given its focus on style.

The Sportage measures 4685mm long, 1865mm wide and between 1665mm and 1680mm tall, depending on the trim.

Slip into the backseat of the Sportage and you’ll find legroom is ample, at least for my 175cm frame, and headroom is ok, without being great - though our test car had the sunroof fitted which could be eating into the space.

Elsewhere in the back though, even the top spec GT-Line just doesn't feel that plush. And by that, I mean some of the materials are a bit hard and scratchy, you don’t get your own temperature controls for the air vents, and it generally just lacks a premium air.

Now, to the all-important point in this segment, and that is boot space. The official VDA numbers are 543-1829 litres for the petrol and diesel cars, and 586-1872L for the hybrid, but the real-world reality is a boot that is deep and wide and really has enough space to carry plenty of groceries.

But there is an important caveat. Under the flat floor there is a temporary spare wheel in the hybrids, where in some of the ICE cars, you get a full-size spare wheel.

There are a lot of different numbers involved in the Sportage story. In fact, there are no less than 13 trim and powertrain combinations, and so 13 different prices you can pay. Easier, I think, if I just pop the graphic up on screen and you can jump to the one you want.

While there are four engines and five powertrain configurations to choose from, not all of them are available across all four trim levels. The SX+, for example, offers no electrified options, while the SX will give you hybrids, but no turbo-petrol choice.

The range opens with the S, which gets 17-inch alloys, LED DRLs, power-folding mirrors and roof rails, while inside there are cloth seats, power windows, a smart key with push-button start, and single-zone air-con with rear-seat vents. Tech at this level is handled by a 12.3-inch infotainment screen with wireless Apple CarPlay and Android Auto, but no wireless charging, which pairs with a six-speaker stereo. The driver then gets a 4.2-inch screen to deliver driving info.

The SX then adds 18-inch alloy wheels, dual-zone climate, standard navigation and rain-sensing wipers.

The SX+ is feeling like a sweet spot, adding 19-inch alloys, LED fog lights, artificial leather seats that are heated up front, wireless device charging, a heated steering wheel and a better Harman Kardon Premium stereo.

Finally, the flagship GT-Line gets the lot, with 19-inch black alloys, or 18-inch wheels in the hybrid, welcome lights, projection headlights, a twin-screen cabin which adds a second 12.3-inch screen for the driver, a powered driver’s seat and a head-up display.

All models also get Kia Connect, which gives you remote access to the vehicle for things like pre-setting the climate, as well as Over the Air updates.

I’ve got to say, though, the flagship Sportage offers largely what the cheapest version of most Chinese SUVs offer, showing just how much price pressure the newcomers are putting on the old guard.

This is the latest iteration of Audi’s twin-turbo 4.0-litre V8 petrol engine - and it’s a beauty.

While this engine is used in a variety of models, for the RS Q8 Performance Audi has taken power to 471kW with 850Nm of torque, which, as mentioned earlier, makes it the most powerful internal combustion engine Audi has ever offered in a production car.

That’s also a big boost over the previous RS Q8, which managed 441kW/800Nm, and is only just shy of the 485kW/850Nm offered by its ‘cousin’, the Porsche Cayenne Turbo GT.

Audi claims that the RS Q8 Performance will launch 0-100km/h in just 3.6 seconds and keep going to an electronically limited top speed of 250km/h. We tried to test the acceleration time on a closed circuit, but driving into a very strong headwind the big SUV could manage only 4.4 seconds - which is still a very quick time given its size and luxury.

The engine is paired to an eight-speed automatic transmission and Audi’s trademark quattro all-wheel-drive system to help smoothly transmit so much power to the road.

The big news about this mid-life update for the Sportage is the expansion of Kia’s hybrid powertrain, which is now available with AWD, and the inclusion of an eight-speed automatic for the 1.6-litre turbo-petrol variants.

Elsewhere, the 2.0-litre petrol option produces 115kW and 192Nm, pairs with a six-speed automatic, and drives the front wheels. The other pure petrol option is a 1.6-litre turbocharged petrol unit that produces 132kW and 265Nm, paired with an eight-speed auto and powering all four wheels.

Then comes the diesel, which is a 2.0-litre unit making 137kW and 416Nm. It pairs with an eight-speed automatic and powers all four wheels.

Finally, there’s a hybrid option, now with two- or all-wheel drive. It pairs a 1.6-litre turbo-petrol engine and a six-speed automatic with an electric motor and a 1.49kWh lithium-ion battery to produce a total 173kW and 367Nm.

Unfortunately you don’t get the most powerful production engine without some trade-off, and for the RS Q8 Performance that means significant fuel consumption. The official fuel economy rating is a very thirsty 12.2L/100km, but that's the best-case scenario too. If you partake in some spirited driving that unleashes the full potential of the engine will result in a higher rate of premium unleaded being consumed by the big V8. We saw returns in the high teens across our time, but that was largely open road driving, so we’ll reserve final judgement for an extended test drive across more varied conditions.

Thankfully there’s a fairly large 85L fuel tank, so if you can hit the claimed average you can get a theoretical 696km of range.

All pure ICE Sportage grades are fitted with 54-litre fuel tanks, while the hybrids get 52-litre tanks. But the hybrids more than make up for it when it comes to fuel efficiency, with the FWD sipping a claimed 4.9 litres per hundred kilometres on the combined cycle, while the AWD drinks 5.3 litres.

The diesel is the next most-efficient, using a claimed 6.3L/100km combined, while the turbo-petrol needs 7.5 litres, and the 2.0-litre petrol requires 8.1 litres.

Our calculations suggest that, taking the fuel claims at face value, a 2.0-litre petrol Sportage should carry you 666kms on a full tank, while a turbo-petrol will take you 720kms. The diesel should deliver 857kms, while the FWD hybrid (1061kms) and AWD hybrid (981kms) will take you the furthest.

Obviously the RS Q8 Performance is all about speed, Audi made its intention clear by sending it to the Nurburgring to set a new SUV lap record for an SUV. But the reality is most owners are unlikely to hit the racetrack in the RS Q8, so what’s it like on the road?

In a word? Impressive.

While the engine is undoubtedly the star attraction offering up so much effortless performance, the RS Q8 Performance wouldn’t be so quick around the Nurburgring or as nice to drive on the road without its highly advanced chassis systems.

It has an array of technology to help it handle, it has active air suspension, adaptive dampers, active roll stabilisation and all-wheel steering, which help to make this big SUV handle like a much smaller car.

The suspension does a remarkable job of providing a compliant ride on such large alloy wheels, while also providing responsiveness.

The handling is certainly helped by the all-wheel steering, which gets the rear wheels to turn in the opposite direction to the fronts at low speed (below 50km/h), but in the same direction at high speed (above 80km/h), making the big SUV feels much more direct when changing direction.

As for the overall experience, that’s helped by Audi’s surprising decision to actually remove some of the sound insulation, which allows you to hear the engine even more than you ordinarily would. This really plays to the dynamic nature of the RS Q8 Performance.

I want to start this with just a small caveat. It hasn't been the most comprehensive drive of this car so far. And remember, there are a lot of variants.

Petrol, diesel, hybrid, two-wheel drive, all-wheel drive – we haven't driven all of them, and so I feel uncomfortable giving you my rock-solid verdict across the whole range. I can, however, give you my first impressions.

The first of those is that whoever in the vast Hyundai group came up with adding a long-hold function to the stereo mute button deserves a medal. By far the most annoying of the modern safety systems is the overspeed warning, which inevitably reads some signs incorrectly, others not at all, and has no idea when school zones actually start.

Thankfully, Kia, like Hyundai, now has the shortcut to mute it. You just long-hold down mute button and voila, the bing-bongs vanish.

Now elsewhere, as is pretty typical of modern Kias, the ride in this car feels properly well sorted. We've taken it through the city, onto the freeway, along a little twisting road section, and on some typically coarse and broken country B-roads, and the Sportage handled them all really well.

And even when you're getting a little frisky with the driving, there's little in the way of body roll, with the Sportage feeling planted and solid.

I wasn't totally blown away with the refinement in the cabin. On the wrong road surface, you definitely get a bit of road noise in the cabin – mind you, that is pretty hard to avoid on the coarse chip stuff – but you can also hear the engines revving away and working hard when you put your foot down.

That said, the way the gearboxes channel that power is smooth and easy, and when you put your foot down in each of the powertrains we tested, there's certainly enough urge to get you up and moving.

And that is especially true in the diesel, which I do think is a bit of a peach of a powertrain – super torquey and super easy to get the Sportage up and moving. It might find itself on the endangered species list, that engine, so get it while you can.

Now, one small downside. While the ride hasn't changed, at least for any of the ICE-powered cars, the steering has changed for all of them, and at speed, it's really lovely. It's quite direct, confidence-inspiring, and nicely weighted.

But at low speeds it can feel a little bit darty, like it takes a really big bite when you put a little input in, and it takes a little bit of getting used to.

All Sportage models start with seven airbags, and even the cheapest S gets a pretty full suite of safety stuff, including a new SOS button should you have an accident, auto emergency braking (AEB) with junction sensing, blind-spot monitoring, lane keep and lane follow assist, a rear-view camera and the often-infuriating speed limit monitoring.

From the SX+ and up you also get Kia’s Highway Driving Assist, which pairs active cruise with a lane entering function, and the GT-Line also gets remote park assist, which allows you to remotely drive into or out of tight spots, along with a blind-spot view monitor and a rear-view monitor.

The Sportage wears a five-star ANCAP rating, which it earned back in 2022.

Despite the extra power and fancy new brakes, the RS Q8 Performance costs the same to service as the existing RS Q8.

That means $4690 for Audi’s five-year service plan, and $5720 for the Audi Advantage.

The latter package includes an extra two-year, unlimited kilometre warranty on top of Audi’s five year/unlimited km coverage. It also includes two extra services and two more years of roadside assistance, to keep you covered for seven years total.

That’s good, but it’s still an extra cost when many mainstream brands already offer seven years of coverage as standard.

All Kia models also get the brand’s seven-year, unlimited-kilometre warranty, seven years of capped-price servicing and, should you service with Kia, eight years of roadside assistance.

Turbo-petrol and hybrid models require servicing every 12 months or 10,000kms, where the rest are 15,000km intervals. The Kia website has the full costings for each powertrain choice, but for reference, seven years of hybrid ownership will cost you a not-insubstantial $4510.
