Genesis GV80 vs Audi RS Q8

What's the difference?

The Genesis GV80 Coupe is a rare breed – it comes packed to the gills with features, has great ownership benefits and can easily accommodate a large family in comfort.

The fuel economy isn’t great but it looks and acts the part of a true luxury SUV. My husband and son were impressed and enjoyed all of the features it has.

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

At first glance, there’s not a lot that separates the external styling of the Coupe and SUV, at least in the front.

The biggest difference is obviously in the rear and it's here Coupe's design shines. The SUV sibling looks nice but is a little boxy at the rear and features a dicky-looking window. The Coupe's rear is pinched but it’s rather softly done compared to some rivals.

It manages to look sleek and sexy as coupes tend to be without losing any of its large road-side presence.

The 'Storr Green Matte' paintwork on our test car highlights the high-end feel, as does the huge LED external lights and chrome accents.

Head into the cabin and you'll find design elements which accentuate the width of the car – like the long air vent strip that runs the length of the dashboard, a wide centre console and the huge 27-inch OLED technology screen that houses the media system and instrument cluster. Even the touchscreen control panel for climate and seat functions is big.

Our test model has a cream-coloured suede headliner and quilted Nappa leather seats that look plush. Contrasting stitching and the seatbelts are a bright red (or dark orange, depending on who you ask) and the panoramic sunroof adds a bright and cheery element.

The ambient lighting surrounds a lot of the features, like the cupholders and the crystal rotary dials. In fact, when you pop the car into reverse, the light changes from whatever it was to red, which is neat.

As far as luxury cars go, this totally looks the part and while design is very subjective, I love how this looks inside and out. Let us know what you think of it in the comments.

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.

With all of its features offering comfort and luxury, practicality is pretty high for the GV80 Coupe.

The cabin feels almost cavernous up front for my 168cm height. As mentioned, the seats are very comfortable and there is a stretching function that briefly comes on during a longer journey to ease any fatigue in your lumbar.

The rear row is almost as large as the front and there's a limo-like quality to the legroom that taller individuals will enjoy. The headroom is good for the outboard seats but a taller adult will be hunched when sat in the middle. Keep that for a kid!

Amenities in this row are excellent with the powered outboard seats that feature heat and cooling functions, directional air-vents, climate control and retractable sun-blinds (my son's favourites). 

The individual storage is a little less than you might expect for such a large car, especially up front, as all options are on the shallow/small side.

There is a middle console (think of it as a tray), glove box, two cupholders, two drink bottle holders and a phone cubby that can be closed to keep things looking neat.

The rear row sees two map pockets, two cupholders and a storage cubby in the fold-down armrest, as well as some shallow bin storage.

Technology looks stellar, is easy to use and found throughout.

You're spoiled for choice when it comes to charging as there are four USB-C ports, three 12-volt sockets and a wireless charging pad to choose from. 

And new for 2025 is the UV-C feature, which sterilises whatever you place inside the middle console. Handy for anyone who wants to disinfect small items, like a phone, keys or wallet.

The multimedia system takes a while to get used to as the tech has been updated but once you do, it’s an easy system. You can access the media system via the touchscreen or the rotary dial. Climate control and seat functions are accessed via the large control panel that sits underneath, which is handy for when you're on the go. 

The GV80 Coupe has built-in sat nav, wired Apple CarPlay and Android Auto, as well as, a 12-inch colour head-up display.

Because of the sleek rear shape, the boot space sits at 644L when all seats are in use. It’s large enough for my gear and weekly errands and I like the powered tailgate's proximity feature. As long as you have the key fob, it will open when you stand at the rear. Great for when you have your hands full.

The loading space is level and the rear seat has a 40/20/40 split, which opens up storage options. But underneath the floor, there are heaps of cubbies for extra storage of smaller items and it’s here the tyre mobility and roadside assistance kits are housed.

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.

Audi updated the Q8 range earlier this year, with refreshed looks after seven years on sale and a plug-in hybrid powertrain to cater for new demand.

A new RS Q8 is coming later in the year, but the RS Q8 Performance has arrived first to make a bigger impact. It naturally gets a performance boost, but there are some other extras beyond more kilowatts.

These include RS ceramic brakes, lightweight 23-inch forged alloy wheels, Pirelli P-Zero tyres, unique aluminium inlays and a special RS layout for the digital instrument display.

Which is good, because the RS Q8 Performance costs nearly $25k more than the ‘standard’ RS Q8, priced from $255,800 plus on-road costs.

Luckily for a car costing a quarter of a million bucks, there’s also plenty of luxuries too, including Nappa leather upholstery, four-zone climate control and a 17-speaker 730-watt Bang & Olufsen sound system, amongst others.

When you compare it to its rivals on performance terms, in particular the Urus and Cayenne Turbo, the $250k asking price doesn’t exactly look ‘cheap’ but it is good value in comparison.

The Audi is a touch pricier than the BMW X6 M Performance at $250,900, but quite a bit more affordable than the Mercedes-AMG GLE63 S Coupe at $268,900.

The GV80 model facelift sees all variants enjoy a powerful 3.5L twin-turbo petrol V6 engine that produces 279kW of power and 530Nm of torque.

The Coupe is an AWD, features an eight-speed auto transmission and can do a 0-100km/h sprint in just 5.7 seconds.

It also has different terrain modes and a braked trailer towing capacity of 2722kg. Whether you’d use this car for that sort of stuff is another matter.

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.

Aye, here's the rub, as the hefty power comes with a thirsty gullet.

The official combined fuel-cycle consumption figure is a hefty 11.7L/100km and my real-world usage came out at 11.4L/100km after doing a lot of open-road trips this week.

I haven’t held back using the power but it's thirsty compared to its rivals which mostly sport mild-hybrid powertrains.

Based on the large 80L fuel tank and official combined fuel cycle consumption figure this car's theoretical driving range is 684km.

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.

The GV80 Coupe has a deep well of power to dip into and fantastic pick up. The power delivery feels effortless and it’s easy for urban and open-road driving.

The GV80 isn't as dynamic on the road as some of its rivals when it comes to the ‘sporty’ factor and you notice that the most when you hit high winds or tackle a tight turn, as there is some roll, but on the whole it’s a smooth ride. Think of it as more ‘stately’ than sporty.

The cabin is mostly quiet but wind noise can creep in at higher speeds.

The wide windows and high ride mean the visibility is very good and so is the sound quality from the 18-speaker Bang & Olufsen audio system. Every school run is a concert!

The GV80 Coupe is large car and will fill out a parking space but it’s not hard to park because the 360-degree view camera system is so good and the projected parking guidelines add assurance in a tight spot. 

There is a remote parking assist feature, where you can move the car remotely from your key fob, which is great for those times someone parks a bit too close and there’s not enough door clearance to get in.

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.

The RS Q8 Performance comes stacked with the full suite of active safety features. These include adaptive cruise control, lane change warning, rear cross-traffic alert and surround-view cameras.

ANCAP rated the Q8 as five stars back when it first launched in 2019 and that rating is due to expire at the end of 2025. However, ANCAP states that it only applies to the 3.0-litre Q8 models, not the V8-powered RS variants.

The GV80 Coupe comes with a five-year/unlimited km warranty and complimentary servicing for five-years or 50,000km, whichever occurs first.

There is also complimentary roadside assistance through Assist Australia for five years.

Since this is a turbo, the servicing intervals are a little annoying at every 12 months or 10,000km but it’s rare for a car brand, let alone a luxury one, to offer anything for free. What Genesis offers is a real plus.

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.
