What's the difference?
Most buyers don’t care for sedans these days, but those in the premium market are still spoilt for choice, with new model after new model being launched.
The latest on offer is the new Audi S6, which once again attempts to mix executive style with boy-racer performance.
With its predecessor’s 4.0-litre twin-turbo V8 succeeded by an engine that is 1.1 litres and two cylinders short, does it still serve up enough bang for your back?
Of course, the only way to find out is to put the new S6 sedan to test, so that’s exactly what we did. Read on.
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.
We adore the new S6 sedan. It looks great, feels comfortable and goes like stink all at the same time. What’s not to like?
It also helps that it is relatively good value, safe and practical by large-sedan standards, so it’s a bit of a no-brainer.
But will buyers be quick to dismiss the new S6 sedan because it’s not a more practical SUV? Time will tell, but we hope not.
Does the new Audi S6 sedan represent the best mix of executive style and boy-racer performance? Tell us what you think in the comments below.
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.
To these eyes, the new S6 sedan is very attractive, albeit not outlandish, in keeping with its executive focus.
Up front, the subtly aggressive S body kit immediately comes into frame, with the bumper sporting sinister-looking side air intakes.
And, of course, there’s Audi’s signature Singleframe, which is not only large and in charge, but also finished in gloss-black, like many of the S6 sedan’s exterior design elements.
Below the heavily creased bonnet, the HD Matrix LED headlights look both angry and sophisticated, with their integrated LED daytime running lights (DRLs) providing a crisp signature.
Around the side, the S6 sedan goes about its business quietly, but its blistered wheelarches do add some bulk and help to accentuate its strong shoulder line.
And then there are the thick skirts and 21-inch alloy wheels (with a space-saver spare), which have a sporty twin five-spoke design. It’s all very classy.
Speaking of which, the rear end is arguably the S6 sedan’s best angle thanks to its wicked LED tail-lights, which have a segmented signature.
The chunky bumper below incorporates a diffuser element that houses the quad exhaust tailpipes, while a blink-and-you’ll-miss-it bootlid spoiler rounds out the look.
Inside, the S6 sedan is a technological tour de force, with 10.1- and 8.6-inch touchscreens dominating its centre stack. The former is responsible for most of Audi’s latest multimedia system’s functions, while the latter takes care of the climate controls.
This set-up works pretty well, although a few too many taps are required for certain functions, and then there’s the issue of the glass display coverings, which are absolute fingerprint magnets alongside the gloss-black accents used throughout.
That said, the 12.3-inch digital instrument cluster and windshield-projected head-up display on hand are brilliant. In fact, they set the standard for the entire industry thanks to their design and breadth of functionality.
The S6 sedan does, of course, feel a little bit more special than the regular A6 inside, with the obvious additions being the front sports seats, which are covered in supple Valcona leather alongside the armrests. They even have diamond-stitched inserts.
Then there’s the obligatory flat-bottom steering wheel (with paddle-shifters), which is trimmed in Nappa leather alongside the gear selector, upper dashboard, door shoulders and knee rests. Indeed, hard plastics are hard to find here.
Meanwhile, a black headliner adds to the sportiness alongside the black Alcantara door inserts, but the cabin is otherwise a familiar (read: classy) affair.
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.
Measuring 4954mm long, 1886mm wide and 1446mm tall, the new S6 sedan is a large sedan in every sense of the term, which is mostly good news when it comes to practicality.
Cargo capacity is decent, at 520L, but can be increased to an undisclosed amount with the 40/20/40 split-fold rear bench stowed.
Speaking of the boot, there are four tie-down points and a cargo net to help secure loose loads, while a bag hook and a side storage net are also on hand, alongside a 12V power outlet. Bulkier items will, however, be confronted by a decent load lip.
In-cabin storage options are numerous, but not all are effective. The glovebox is well-sized, while the driver-side cubby is surprisingly large, but the central bin is shallow, mostly taken up by the wireless smartphone charger, two USB-A ports and the SD and SIM card readers.
A pair of cupholders is located in the centre console, with a 12V power outlet found in between, while the front door bins can accommodate one regular bottle each, just like their rear counterparts.
In the second row, there’s a fold-down armrest with two more cupholders as well as a shallow storage tray, while cargo nets are affixed to the front seat backrests.
The rear bench is pretty comfortable, with four inches of legroom available behind my 184cm driving position alongside decent toe-room. Headroom is also good, with about two inches on offer.
That said, three adults sitting abreast won’t enjoy the experience, due to the large transmission tunnel, which makes for limited footwell space. At least they’ll have access to a couple of USB-A ports and a 12V power outlet, below the central air vents.
For reference, child seats can be fitted to the outboard seats via top-tether and ISOFIX anchorage points.
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.
The new S6 large sedan is priced from $149,900 plus on-road costs and is far better value than before, even if it does command a $33,900 premium over the regular A6's flagship variant.
Compared to its predecessor, the new S6 sedan is $21,480 cheaper, while Audi Australia claims it has also added $20,000 worth of kit.
Standard equipment not already mentioned includes metallic paintwork (our test vehicle was finished in Tango Red), dusk-sensing lights, rain-sensing windshield wipers, soft-close doors, auto-folding side mirrors with heating, rear privacy glass and a hands-free power-operated bootlid.
Inside, satellite navigation with live traffic, Android Auto and wireless Apple CarPlay support, digital radio, a 705W Bang & Olufsen 3D sound system with 16 speakers, a panoramic sunroof, keyless entry and start, power-adjustable front seats with heating, a power-adjustable steering column, four-zone climate control, an auto-dimming rearview mirror and LED ambient lighting feature.
Of note, buyers can opt for the $7700 Dynamic Package that bundles in speed-sensitive electric power steering, a rear limited-slip differential and all-wheel steering. It was not fitted to our test vehicle.
In terms of rivals, the BMW M550i sedan is identically priced, while the Mercedes-AMG E53 sedan is much more expensive, at $173,800. The S6 sedan arguably has the former beat on value but loses the performance battle due to its 390kW/750Nm 4.4-litre twin-turbo V8.
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.
The new S6 sedan is powered by a hard-hitting 2.9-litre twin-turbo V6 petrol engine that produces a strong 331kW of power from 5700-6700rpm and a punchy 600Nm of torque from 1900-5000rpm.
Compared to its aforementioned predecessor, power is unchanged, while torque has increased by 50Nm.
This unit is mated to a 48V mild-hybrid system that includes a trick Electric-Powered Compressor (EPC), which helps to reduce its turbo lag.
A reliable eight-speed torque-converter automatic transmission is responsible for swapping gears, while drive is sent to all four wheels via Audi’s rear-biased quattro system.
This combination helps it sprint from a standstill to 100km/h in an impressive 4.5 seconds, while its top speed is electronically limited to 250km/h.
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 new S6 sedan’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.4 litres per 100 kilometres, while claimed carbon dioxide emissions are 197 grams per kilometre. Both figures are pretty keen given the level of performance on offer.
Audi says the aforementioned 48V mild-hybrid system reduces fuel consumption by 0.4L/100km thanks to its coasting ability, which sees the engine turn off for up to 40 seconds between 55km/h and 160km/h. It also engages idle-stop from 22km/h.
In our real-world testing, we averaged 14.4L/100km over 100km of driving skewed towards country roads over city traffic, with limited highway time. It’s worth noting that my spirited driving inflated this result. That said, while its fuel consumption is not as bad as it appears, this is still a thirsty sedan.
For reference, the S6 sedan’s 73L fuel tank takes 98RON petrol at minimum.
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 S6 sedan has no right being this good in a straight line and around corners…
Much of its success is owed to the 2.9-litre twin-turbo V6, which is now one of my favourite engines being built today. Simply put, it absolutely hammers.
Punch the accelerator from a standing start and it doesn’t take long for 600Nm to be on tap all the way through, and just a little bit beyond, the mid-range.
Occupants are firmly pressed into their seats as the S6 sedan sprints towards the horizon with vigour. Soon enough, 331kW arrives and hangs around until just prior to the redline.
Needless to say, this acceleration is addictive, and the EPC deserves some of the credit, as it effectively mitigates any dreaded turbo lag and ensures the engine is always seemingly on boost.
But we also need to acknowledge the eight-speed torque-converter automatic, which is a real beauty. Gear changes are nice and smooth, which is great, but what’s even better is their relative quickness – dual-clutch transmissions be damned!
Of course, extra performance can be extracted by switching between the engine and transmissions’ settings but, rest assured, they both stand up, no matter what.
However, we’d suggest spending time in the former’s most aggressive setting, as it unleashes the sports exhaust system, which sounds unreal.
Upshift with intent and you’re met with a booming ‘brap’. Downshifts and the overrun will even gift you a series of pops. In fact, the S6 sedan soundtrack sounds strangely similar to that of the five-cylinder RS3, and we have absolutely no problem with that.
Better yet, the S6 sedan has an appetite for corners, with its neutral handling a standout, partly thanks to its hard-working rear-biased quattro all-wheel-drive system, which works in tandem with all the other electronics to ensure there is plenty of grip at any given time.
This controlled driving pleasure is enhanced by the electric power steering on hand, which has a variable ratio. At low speed, it’s nice and light, but those after more heft can always switch to another one of its settings, which become progressively heavier… arguably too heavy.
Feedback through the wheel is also good, while the steering itself is pretty direct, lending itself to sporty driving, which, of course, is half of the S6 sedan’s mantra.
Coming into corners, braking performance is solid, thanks to the massive 400mm front and 350mm rear discs with red callipers, so the driver is brimming with confidence at every turn, even though there’s an unladen weight (with 75kg driver and luggage) of 1985kg to manage.
But let’s not forget the S6 is an executive sedan, so it has to ride like one. Thankfully, it does. The independent five-link suspension has air springs and adaptive dampers, which serve up comfort in spades, especially at high speed.
Its firm tune does come into frame when travelling on unsealed or uneven roads, with this exacerbated by the large 21-inch alloy wheels, which have a penchant for catching sharp edges.
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.
ANCAP awarded the A6 range (including S6) a maximum five-star safety rating in 2018.
Advanced driver-assist systems extend to autonomous emergency braking with pedestrian detection, lane-keep and steering assist, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control with stop-and-go functionality, high-beam assist, driver attention alert, hill-start assist, tyre pressure monitoring, surround-view cameras and front and rear parking sensors. Yep, buyers aren’t left wanting here.
Other standard safety equipment includes six airbags (dual front, side and curtain), electronic stability and traction control systems, anti-skid brakes (ABS), brake assist and electronic brake-force distribution, among others.
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 S6 sedan comes with Audi Australia’s three-year/unlimited-kilometre warranty, which falls short of the premium market’s relatively new five-year standard that was set by Genesis and followed by Mercedes-Benz.
Three years of roadside assistance is also bundled in, although this term can be extended up to nine years if the vehicle is serviced at an authorised dealership, which is great.
Speaking of which, service intervals are every 12 months or 15,000km, whichever comes first. Capped-price servicing plans are available, costing $2350 for three years/45,000km or $4110 for five years/75,000km. They’re pricey, but you weren’t expecting the opposite.
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.
