Audi RS Q8 vs Land Rover Discovery

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.

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

The Land Rover Discovery 35th Anniversary Edition drives beautifully, with effortless power and a composed, comfortable ride. It’s elegant and well-equipped for its price, though the technology often frustrates, and it’s not as spacious as some seven-seater rivals. Small quirks in everyday use prevent it from fully standing out in a competitive segment but it does enough to be considered.

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.

The Discovery remains a handsome SUV. It isn’t as boxy or rugged-looking as some of its rivals, but it still carries a quiet confidence and a hint of adventure in its stance. The 35th Anniversary Edition gets a few subtle touches to help it stand out, including 21-inch black alloy wheels, roman-numeral anniversary badging and slim LED lighting signatures that give it a clean, sophisticated look.

Inside, everything feels solid and thoughtfully put together, with soft-touch materials in all the right places. Some of the trim finishes lean a little synthetic, but the leather upholstery is beautifully done and the dual sunroofs bring in plenty of natural light, which helps elevate the cabin ambience.

The 11.4-inch media display takes pride of place on the dash and looks premium, and there are enough physical buttons and dials to satisfy those who like some tactile-functionality. That said, the cabin doesn’t quite deliver that sense of occasion you might expect at this price. It’s nice, it’s just not especially distinctive.

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 Discovery’s cabin is an interesting mix - at first glance it seems to offer the right balance of space and features, but once you settle in, a few small disconnects between technology and layout become apparent.

Up front is where you want to spend most of your time. The powered seats are well-padded with long bases and excellent lumbar support. There’s plenty of room for tall drivers and passengers and elbow space is generous. The only annoyance is the heated seat function, which is buried behind the menu system and the fiddly climate dials.

The middle row highlights the Discovery’s tall-but-narrow proportions. Adult passengers can feel a little cramped side-to-side, though the flat floor gives decent leg and foot room. The third-row surprises with wider seats and deeper footwells than expected, so knees aren’t pressed against chests. Access, however, is more suited to children than adults.

Storage is abundant and thoughtfully positioned. Up front, there are dual glove boxes (one lockable), a hidden cubby behind the climate panel and underneath the sliding cupholders, a tray housing the wireless charging pad (which, in our test car, didn’t work), and the middle console fridge which is a handy touch for keeping snacks or drinks cool on long trips. The middle row gets map pockets, cupholders and bottle storage, while the third-row benefits from hinged cubbies on each wheel arch.

The boot is the standout, offering a massive 1137L when the third row is folded. Its tall and deep shape makes it practical and features like the powered tailgate, adjustable boot-lip height via air suspension, a full-size spare and a 12 volt socket round out its friendly usability.

Access is a simple step-in and step-out scenario thanks to the Discovery’s 'Auto Comfort Access' mode which, when activated, lowers the vehicle when parked. That said, the doors are heavy and need a firm push to latch properly.

Technology is a bit of a mixed bag. The media system is somewhat intuitive once you spend time with it, but newcomers may find the layout confusing. It includes sat nav, wireless Apple CarPlay, and Android Auto, though in our test car, CarPlay occasionally showed music playing without sound but re-pairing my iPhone 15 Pro Max fixed the issue. The dual-use climate dials, which control temperature, fan speed and seat heating, can feel finicky, and one rear door locked itself for four days despite troubleshooting. The rear seat fold controls also worked inconsistently.

On the plus side, amenities like four-zone climate control, multiple air vents per row, and seven USB ports scattered throughout the cabin are thoughtful touches.

Since the launch of the 35th Anniversary Edition, the Discovery line-up has shifted, now trimmed to five diesel-powered grades. Originally based on the Dynamic SE, this special edition is based on the Gemini variant which is second from the top of the range.

Pricing starts from $132,090 MSRP, placing it above key rivals like the Lexus GX 550 Luxury ($112,607) and Toyota LandCruiser Prado VX ($87,400). In other words, it’s priced right in the middle of the family-luxury SUV battlefield.

Inside, you get heated and powered chairs up front with four-way lumbar, plus heated outboard second-row seats. There’s no heated steering wheel or front seat ventilation, which feels like a miss at this price point, but the equipment list remains generous. Standard highlights include an 11.4-inch media screen, satellite navigation, dual sunroofs (one fixed), wireless Apple CarPlay and Android Auto and a premium Meridian sound system.

Family practicality is well-covered with a hands-free powered tailgate, adjustable load height, full-size spare wheel, 360-degree camera system, five USB-C ports, two USB-A ports, two 12-volt sockets and directional vents in every row. You also get seating flexibility and family-friendly safety points: four ISOFIX mounts and five top-tether anchors across the back rows.

The Anniversary Edition builds further with rear privacy glass, a Wi-Fi-enabled media system (with data plan), colour head-up display, power-tilt/fold second-row seating, tow pack (including hitch receiver and tow assist), anniversary badging, black roof rails, centre console 'fridge' and four-zone climate control.

Our test vehicle also features the 'Capability Plus Pack' ($4910), which adds meaningful off-road hardware like a rear differential lock, twin-speed transfer case (high/low range), multi-terrain modes (including 'Grass', 'Gravel', 'Snow', 'Mud-ruts' and 'Rock Crawl') and a wading sensor. Land Rover’s 'All-Terrain Progress Control' (essentially a low-speed, off-road cruise control) is also included.

It offers a well-rounded feature set that keeps it competitive, though a handful of additional premium touches would elevate it to a more commanding position in the segment.

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 35th Anniversary Edition runs a hefty 3.0-litre, six-cylinder, twin-turbo diesel paired with a 48V mild-hybrid system. Together, they produce 257kW and 700Nm. It’s brisk, too, with a 0-100km/h sprint time of 6.3-seconds, which is impressive for such a large 4WD.

Towing is rated at 3.5 tonnes and wading depth sits at 900mm, reinforcing its credentials as a proper adventure vehicle. Our test vehicle also features the 'Capability Plus Pack', which brings low-range gearing, rear differential lock and multiple terrain modes.

Not too bad for something that looks more like a school-run luxury SUV than some of its rivals.

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 35th Anniversary Edition has a claimed combined fuel figure of 7.8L/100km, and with its 89-litre tank you’re looking at a theoretical driving range of around 1141km. In the real world, I saw 9.0L/100km - that’s with one longer highway run mixed into a week of school runs and suburban errands.

It’s a touch thirstier than I’d hoped given I wasn’t towing or carrying heavy gear, but it still sits comfortably within expectations for this segment and size of vehicle.

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.

Power delivery in the Discovery feels effortless, with none of the laggy, heavy character you can get from some big diesels. It responds quickly when you need it to, whether you're merging into traffic or overtaking and always feels like it has plenty left in reserve.

Ride comfort is excellent. The adaptive suspension absorbs bumps and settles the body confidently through corners without feeling floaty or wallowy. Steering has a reassuring weight to it - not too light, not too heavy - which helps the Discovery feel sure-footed and composed on the road.

The cabin is impressively quiet, making it easy to chat with passengers across all three rows and reducing fatigue on longer drives. Visibility is generally strong and the high seating position gives a good command of the road. The only drawback is the middle-row headrest, which blocks the rear view. A digital rear-view mirror would be a helpful addition, especially when the car’s full.

Despite its size, the Discovery is surprisingly easy to manoeuvre, with a fairly forgiving 12.7-metre turning circle. Parking is straightforward thanks to a clear 360-degree camera system, although the display itself could be larger. Even in tight shopping centre car parks it never feels unwieldy.

The new Discovery hasn’t been tested by ANCAP yet and is unrated but it does come with a large suite of safety features and eight airbags which is good to see on a large 4WD.

Standard equipment includes autonomous emergency braking, blind-spot monitor, driver attention monitor, lane keeping aid, rear collision alert, rear cross-traffic alert, traffic sign recognition, speed limit warning, intelligent seatbelt warning, powered child locks, front/rear parking sensors and a 360-degree view camera system.

The adaptive cruise control is well-calibrated as it slows smoothly behind traffic and confidently builds speed again once the lane clears, without the hesitation some systems have. The only safety feature which is intrusive is the speed limit warning and unfortunately you have to slough though some menus to mute it.

There are four ISOFIX and five top-tether anchor points spread across the rear rows, which should delight families.

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.

The Discovery 35th Anniversary Edition is covered by a five-year/unlimited-kilometre warranty, which is fairly standard for vehicles in the luxury SUV segment. However, it's worth noting the Nissan Patrol is offered with a 10-year (conditional) warranty.

Land Rover offers a pre-paid, five-year service plan for around $3500, which is cheaper than paying for each service individually. Service intervals are well spaced at every 12 months or 20,400 km, whichever comes first. There are approximately 71 authorised Land Rover centres across Australia, so even if you live regionally, you should be able to service your Discovery fairly easily.
