What's the difference?
The Audi SQ8 has had a mid-life refresh but this upper large SUV still offers luxury with its powerful V8 engine that fans know and love, as well as the features you would expect in a top model.
It competes against the Mercedes-AMG GLE and Porsche Cayenne but we’re family testing the SQ8 to see how it handles domestic life.
Keep reading to see what we’ve discovered.
BYD has achieved much success in recent years in Australia and it's now branching out with a new, more premium brand.
Denza is like the Lexus to Toyota and it’s launching in Australia with two large body-on-frame plug-in hybrid (PHEV) SUVs – the B5 and B8.
The former is on test here and its rivals include mainstream models like the GWM Tank 300 PHEV, however it also pitches itself against more premium offerings like the Land Rover Defender.
We’ve already driven the B5 over in China and this is the first time we’re getting to test it out on Australian roads, so let’s see how it fares.
The Audi SQ8 isn’t your typical performance SUV. It’s more refined and less flashy. The tech can be more complicated than it needs to be and if you’re wanting that V8 soundscape, you won’t find it here.
However, the handling and on road experience are superb plus you can comfortably haul the family around and look good doing it.
Denza has made a huge statement with the B5 and for the most part the hype is deserved. It packs an incredible amount of luxury and tech inside and out which is even more surprising given the impressive asking price.
There are only a few flaws like the busy ride, over-the-top body roll and the occasional infotainment quirk. Hopefully these can be fixed with future over-the-air software updates.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
The SQ8 is a gorgeous coupe-style SUV that looks purposeful and poised with its balanced proportions and wide stance. It’s stands apart from its siblings thanks to the S-styled nose treatment and our test model's black accent package makes the honeycomb grille look even sportier.
The update sees new air intake vents at the front, matrix LED headlights and new chrome exhaust tailpipes.
The upgraded 23-inch alloys with red calipers behind them hint at what’s under the bonnet, as does the Sakhir (sack-heer) Gold paintwork which is aptly named after the one-off Grand Prix race circuit.
The interior looks luxuriously appointed with the black Valcona leather upholstery and the dash is headlined by three high-end technology screens. The SQ8 also gets sport seats featuring a quilted design and 'S' badging but there’s not much else separating it from its siblings.
Audi fans will love the the SQ8's more understated interior but newcomers might be surprised it's not as flashy as some of its rivals.
It’s worth calling out straight away that the Denza B5 is essentially an SUV version of the BYD Shark 6 as the two share underpinnings, but it’s much more luxurious and blingy.
Externally it has a big, boxy and bluff design that helps it stand out on the road. It looks even tougher when the suspension is in its lifted mode.
I particularly like the front fascia with the big headlights and the prominent Denza badge on the grille, but there are some strange body creases around the side.
While the boxy looks make the B5 stand out, it’s not necessarily unique. There are elements that are reminiscent of the Land Rover Defender, plus many angles look similar to the GWM Tank 300.
Inside is where the luxe is dialled to the max. There are so many soft touches around the cabin that it makes a lovely place to spend time.
Additionally there is a lot of high-quality physical switchgear which is surprising given how prominent the large 15.6-inch central touchscreen is.
Lastly, I like how substantial many of the finishes are. There are large grab handles on either side of the dashboard which you do need to use to hoist yourself into the cabin, plus chunky interior door handle pulls that are satisfying to use.
The upper large SUV tag certainly makes sense when it comes to cabin space because there's a lot of it. Both rows enjoy ample head- and legroom and access is great thanks to wide door apertures and high ground clearance.
Comfort is high with well-padded seats and thanks to the Sensory Package all but the middle back seater get some luxury extras.
The centre rear position has compromised legroom courtesy of the transmission tunnel, so it's best for a kid. However, the front seats take the cake with their massage, heat and cooling functions and adjustable supports.
Amenities are great throughout the car and the extendable sun visors, rear electric sunshades, soft-close doors and four-zone climate control clinch the practicality deal.
Individual storage is a bit sparse up front with two cupholders, a drink bottle holder in each door and a shallow middle console that realistically only fits a phone.
The glove box is a great size. I can fit my handbag in it, but there are not a lot of areas to pop your smaller items in.
Individual storage is a bit better in the rear as you get two big map pockets, a drink bottle holder in each door, plus two cupholders in the fold-down armrest - so it feels like you have more places for your bits and pieces.
Technology looks amazing but overwhelming to use until you wrap your head around it all. The haptic feedback also gets tired fast. The built-in satellite navigation is super simple while the head-up display and digital instrument cluster feature pull through directions, which is handy.
Charging options are good with each row getting two USB-C ports and a 12-volt socket but the front also enjoys a wireless charging pad. The pad is slow to charge, though, and left my iPhone feeling super hot whenever it was used.
The boot is a good size at 605L and easy to access, too. The sloping roof means larger items have to sit flush with the seats but you shouldn’t have to worry for road trips.
The back seat has a 40/20/40 split which opens up storage options and this model has a powered tailgate.
Many Chinese cars have lots of bling but lack actual substance when it comes to comfort and usability. This is where the Denza differs.
Take the driver’s seat, for example. In a number of Chinese cars they look plush and comfy, but in reality they are firm after longer drives and lack adjustability.
The B5’s driver’s seat, however, is very comfortable, offering almost limitless adjustment, plus heating, ventilation and even a massage function as standard. The latter is great for longer road trips.
Ahead of the driver the steering wheel has plenty of adjustment, allowing people of different heights and statures to get comfortable behind the wheel. There are also lots of physical buttons and switches that have a satisfying click when pressed.
The digital instrument cluster is high-resolution and clear, and there's a number of different informative pages that you can cycle through. It’s nice to have this level of customisation.
Moving across, the aforementioned 15.6-inch touchscreen multimedia system dominates the dashboard. If you’re familiar with the user interface in other BYD vehicles, it’s virtually identical in the B5.
It’s very easy to navigate around and if you do get lost there are a number of shortcut buttons at the bottom of the screen that can either take you back home or to other key functions.
One of my favourite features about the screen is the swipe-down control centre menu. You can customise it to have key shortcut functions. It’s much better than having to dig through countless submenus.
It’s clear Denza still has a few kinks to iron out with the translations from Chinese to English as some don’t make sense. Denza will likely sort this with future software updates.
As standard there is wireless Apple CarPlay and Android Auto and it takes up the full screen when connected. It’s a stunning set-up, though reaching the far left-hand side of the screen from the driver’s seat can be a little tricky on the move.
As I touched on earlier, there is a lot of physical switchgear around the cabin which is helpful as you don’t need to solely rely on the touchscreen for key functions. The piano key buttons for the drive and EV/HEV modes are particularly handy, plus the rising gear shift lever is premium-feeling.
In terms of storage up front, there are up to two 50W wireless chargers (depending on the variant you opt for) with ventilation, two cupholders with adjustable depths, some shallow storage under the centre console, plus a fridge/hotbox under the centre armrest.
Moving to the second row there is plenty of space for at least two adults to sit comfortably. Pushing it to three may be a little tight with shoulder room, plus the centre seat is raised compared to the outboard ones. It’s worth noting though that there is a flat floor so you don’t need to fight for foot space.
Second-row amenities include chunky grab handles for easy ingress and egress, air vents on the back of the centre console, as well as heated and ventilated outboard seats in the top-spec Leopard trim. It’s properly luxe.
At the back the tailgate is side-hinged which can be problematic if you reverse into a carpark as you need to allow for space for it to open up. It has a soft-close function which is handy as you don’t need to slam it shut.
There’s 470L of boot space with the rear seats upright, expanding to around 1000L when folded. It’s a decent amount of space and is square with a very minimal load lip.
Amenities include a 12V socket, a wide array of hooks and nets, as well as a small storage space under the boot floor for the charging cables.
Lastly the B5 comes with a full-size spare wheel mounted on the tailgate. This is becoming increasingly rare in electrified vehicles and is very handy if you have a puncture.
There are three fuel-based variants for the Q8 and the model on test is the top-spec SQ8 TFSI quattro. Its mid-life refresh has seen a price hike of $10,015, bringing it's before on-road costs price to $178,815.
Our test vehicle has also been fitted with a few extras, like a 'Sensory Package' ($14,400) which includes a black headliner, upgraded 23-speaker Bang & Olufsen 3D surround sound system, massage function for the front seats, heat function for the rear outboard seats, electric sunshades for the rear row and an air-quality perfume function.
Also fitted are various black and matt carbon accents across/inside the body for a total of $5400, optioned 23-inch alloy wheels ($3000) and specialised 'Sakhir Gold Metallic' paintwork for $1600. Which brings the total MSRP price tag to $203,215.
Even with all of these extras, the SQ8 is still the most affordable performance SUV compared to its nearest rivals as the Porsche Cayenne GTS starts from $212,600 MSRP and the Mercedes-AMG GLE 63 outstrips them both at $272,300 MSRP.
As you'd expect the standard features list is robust for the SQ8 and includes premium features like a panoramic sunroof, electric front seats with heating/cooling and memory functions, full-leather upholstery, soft-close doors and a heated steering wheel.
There is a bunch of high-end technology throughout which includes a colour head-up display, 10.1-inch touchscreen multimedia system, 8.6-inch climate control panel, 12.3-inch digital instrument cluster, satellite navigation, wired/wireless Apple CarPlay and Android Auto, digital radio, four USB-C ports, three 12-volt sockets and a wireless charging pad.
Practical features include keyless entry and start, rain-sensing windscreen wipers, dusk-sensing LED headlights, a powered tailgate, adaptive air-suspension and four-zone climate control.
Overall, not a bad list of features for this part of the market and you won't be left wanting.
The 2026 Denza B5 is offered in two trim levels – entry-level and the top-spec Leopard. Pricing for the former is $74,990 before on-road costs, while the latter is $79,990 before on-road costs.
This is very competitive and it undercuts many top-selling rivals like the diesel-powered Toyota Prado and Ford Everest by a significant margin if you want similar levels of specification.
It’s worth noting however, the GWM Tank 300 PHEV, which is the B5’s closest rival in terms of powertrains, is even cheaper at $59,990 drive-away.
As a base, the B5 is loaded with standard equipment. You get 18-inch alloy wheels, adaptive LED headlights, a glass panoramic sunroof, 12.3-inch digital instrument cluster, 15.6-inch touchscreen multimedia system, 16-speaker Devialet sound system, leather upholstery, heated and ventilated front seats with a massage function, plus heated outboard rear seats.
If this isn’t enough, the B5 Leopard gets larger 20-inch alloy wheels, adaptive hydraulic suspension, a digital rear-view mirror, a second wireless phone charger, Nappa leather upholstery and ventilated outboard rear seats.
This amount of standard equipment is wild, especially because the asking price is firmly below $100K.
Our test vehicle has a 4.0-litre, twin-turbo petrol V8 engine that produces 373kW and 770Nm. That means it sits in the middle of its rivals in terms of outputs with the Mercedes being top-dog with its 450kW/850Nm combo.
Still... the SQ8 is no dainty flower when it comes to power delivery and has an impressive 0-100km/h sprint time of just 4.1 seconds.
The SQ8 is a full-time all-wheel drive with an eight-speed auto transmission and the whole engine combo delivers a powerful but elegant on-road experience.
Power comes from plug-in hybrid set-up combining dual electric motors (one on each axle) and a 1.5-litre turbocharged four-cylinder petrol engine.
It’s a similar set-up to the BYD Shark 6, but the B5 has more power. Total system outputs are a meaty 400kW and 760Nm, which is good for a claimed 0-100km/h sprint in just 4.8 seconds.
Power is sent to all four wheels and for added peace of mind off-road there are front and rear mechanical diff locks as standard, plus a wide range of drive and terrain modes, including a low-range mode.
Backing this up is a 3000kg braked towing capacity and up to 600kg of payload.
The official combined (urban/extra-urban) fuel cycle figure is 11.9L/100km, which is lower than its rivals.
My real world usage sits at 12.3L/100km after a mix of open-road and urban driving.
This result is decent for a performance SUV but expect it to be thirsty in an urban environment as the on-board gauge hit the mid-20s in the city.
Based on the large 85L fuel tank theoretical driving range is 714km and around 690 using our real-world result. Respectable for a performance SUV but not as good as some family SUVs.
Feeding the electric motors is a 31.8kWh lithium iron phosphate (LFP) Blade battery which Denza claims to allow the B5 to travel up to 100km on electric power alone, according to NEDC testing.
There’s also vehicle-to-load (V2L) capability with 6.6kW output through the charging port using an adapter. This allows you to use the battery charge to power appliances. It’s handy if you go camping, for example.
The battery can be AC charged at rates up to 11kW or DC fast-charged at rates up to 100kW.
There’s also an 83L fuel tank. Denza claims the B5 has a total range of 975km, according to NEDC testing.
Fuel consumption depends on whether or not you charge up the battery. Denza claims you’ll use 1.9L/100km from 100 to 25 per cent battery charge and 9.5L/100km under 25 per cent battery charge, both according to NEDC testing. Regardless, this is better than similarly sized diesel-powered SUVs.
The SQ8 delivers on power because it’s effortless to get up to speed and the pick up is super responsive when the start/stop function is turned off (otherwise there can be some lag).
The engine doesn’t sound like a big and grumbly V8, though. There are some growls but it’s mainly when you turn the engine on and not to be obnoxious about it but if you're in a V8, you want to hear it as it’s part of the fun of having a big bruiser engine like this!
What doesn’t help the V8 soundscape is the fact the cabin sounds like a noise-cancelling headphone inside. There is a small hum from road noise but it’s pretty darn quiet. Almost EV quiet at times but that means the driving experience leans more towards refined and elegant rather than sporty and fun.
The SQ8's handling is great - super direct steering, stable in corners and well-rounded passenger comfort when it comes to suspension.
You still get road feedback, which I like as a driver, but it’s not too stiff thanks to the adaptive suspension.
The SQ8 is a large car but you wouldn’t know it when it comes to parking. The 360-degree view camera is clear and the dynamic guidelines help you to position this big unit even the smallest of car parks.
Behind the wheel the Denza B5 primarily operates as an electric vehicle (EV) first up, meaning it’s largely quiet inside the cabin when driving around normally.
Once the charge starts to drop, the petrol engine typically switches on to top up the battery. It largely acts as a generator and a lot of the time you can’t actually tell whether it’s on or off.
In some cases where you floor the throttle or go up a steep hill, the engine revs can flare and that’s when it makes its presence known in the cabin.
When the battery charge gets down low enough and you gun it, the petrol engine can directly power the front wheels. This is rare though because the car purposefully leaves at least 25 per cent battery charge in reserve.
With 400kW and 760Nm thanks to the combination of the dual electric motors and the 1.5-litre turbo-petrol engine, the B5 absolutely hauls. The peppy feel is largely due to the instantaneous torque the electric motors provide.
However, in the standard drive mode there is a noticeable input lag from when you push the accelerator a bit harder and when the car actually accelerates. This is reduced in the sport drive mode.
Despite the juicy outputs, the B5 does feel its weight. When you accelerate hard it pitches back extensively, much like the Jeep Grand Cherokee Trackhawk. This never failed to make me smile though.
It’s surprising as we only drove the top-spec B5 Leopard on this launch and it comes fitted with the DiSus-P adaptive hydraulic suspension system which has a self-levelling function.
In the bends the B5 gets a considerable amount of body roll regardless of the drive mode. This is common for many Chinese cars as they typically prioritise floaty comfort-oriented tunes over a firmer and more dynamic-feeling ride.
Despite this, once it leans over it’ll comfortably hold and grip, largely thanks to the chunky 275/55 R20 Pirelli Scorpion tyres that come standard on the top-spec Leopard trim.
Like many body-on-frame vehicles, the ride gets busy on harsher roads with more frequent bumps. As a passenger you can get jostled about in the cabin.
The steering, while direct enough, can have a vague and artificial feeling. Depending on the drive mode it either artificially adds or reduces the resistance.
Unlike the related BYD Shark 6, the B5 gets a low-range mode which uses a clutch pack on the rear electric motor to allow for more controlled low-speed crawling, plus front and rear mechanical diff locks. This can make a big difference once the going gets really tough.
Additionally, the DiSus-P hydraulic suspension allows for a total of 140mm of travel. In the highest position there’s a wading depth of up to 790mm.
Lastly in terms of noise, vibration and harshness (NVH), the B5 is a very quiet car to drive. As I mentioned above, the electric-first nature automatically makes this a quiet car.
There is very little road and wind noise. This is surprising as the B5 is essentially a 3.0-tonne box on wheels. It seems Denza has put a lot of effort into sound insulation.
The SQ8 has a maximum five-star ANCAP safety rating from testing done in 2019 and features eight airbags, including side chest airbags for both rows. It's common to only find the latter in the front – so that’s great for a family car.
The SQ8 scored well across its ANCAP individual protection segments, scoring 93 per cent for adult occupant, 88 per cent for child occupant, 71 per cent for vulnerable road user and 75 per cent for its safety assist.
The SQ8 has a long list of safety features including blind-spot monitoring, safe exit warning, driver attention monitor, fatigue reminder, matrix LED lights, SOS call, forward collision warning, rear collision warning, rear cross-traffic alert, lane keeping/departure aids, tyre pressure monitoring, adaptive cruise control (with stop & go and lane keeping), park assist and a 360-degree reversing camera plus front and rear parking sensors.
The rear row features two ISOFIX child seat mounts and three top tether anchors.
The SQ8 has AEB with car, pedestrian, and cyclist detection and is operational from 10 – 250km/h but it is usual to see this system operate from as low as 4.0km/h.
The Denza B5 received a five-star ANCAP safety rating based on testing conducted in 2025.
As standard there are 11 airbags, autonomous emergency braking (AEB), blind-spot monitoring, front and rear cross-traffic alert, adaptive cruise control, a driver attention monitor, front and rear parking sensors, plus a surround-view camera.
While a number of the active safety systems operate well and only intervene when required, some are intrusive and over the top. The worst offender is the driver attention monitor which struggles to detect your eyes with sunglasses on, plus only requires a brief glance at the touchscreen to get it saying, “Tiredness detected, please take a rest”.
Thankfully you can turn this off using the touchscreen with the handy swipe-down control centre menu, but it needs to be done every time you drive the car.
The SQ8 comes with a five-year/unlimited km warranty, which is a normal term for the class.
It also comes with capped servicing for five years or up to 75,000km and averages $920 per service, which is very good for the segment.
Servicing intervals are reasonable at every 12-months or 15,000km, whichever occurs first.
Denza B5 owners are covered by a six-year, 150,000km warranty, whereas the high-voltage battery is covered for eight years or 160,000km. Owners also receive three years of roadside assistance.
This warranty length is fairly standard in the mainstream segment, but in the luxury segment it pushes past the current five-year benchmark.
Logbook servicing is required every 12 months or 20,000km, whichever comes first. The first five years of servicing totals $3542, which averages out to just over $700 per service. This does seem like a lot, but in the premium space this is rather competitive, especially once you consider both the electric and combustion components are being serviced.
There are currently seven Denza dealers around Australia and it plans to have a total of 20 by the end of 2026. It’s also planning to allow certain BYD dealers to service Denza cars.
