Audi A4 vs Denza B5

What's the difference?

The Audi A4 allroad 40 TDI quattro S Tronic is a nice-looking wagon that’s fun to drive.

It’s packed with tech, adequately functional for daily life and it’s also capable enough off-road as long as the driving surface is nothing more challenging than well-maintained gravel or dirt tracks in dry weather, and you’re not planning a rough-and-tumble expedition into remote bushland.

As I mentioned earlier, the great thing about adventures is that you can scale them to suit you and your vehicle and the allroad offers a nice stepping-stone for people who’d like to experience the outdoorsy lifestyle, before perhaps diving deeper into 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 allroad’s overall look is part of a range-wide refresh and it certainly fits in with the line-up’s updated aesthetic.

Because I’m a bloke who spends the bulk of my time in 4WDs – traditionally bulkier vehicles rather than slim city-friendly wagons – I’m not totally enamoured of the Audi’s style, especially in terms of trip-packing practicality. However, I can certainly appreciate the appeal of its quite low, sleek and streamlined appearance, which its tweaked chunkier grille adds some gravitas to. It’s just not my cup o’ tea.

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.

I’ll answer that question as a politician would – without actually answering the question.

The allroad’s interior looks good and certainly feels open and spacious, although the driver’s seat tends to feel a bit more snug as the dash is angled towards that position.

The new 10.1-inch touchscreen, home for most upfront functions, dominates the dash, in a good way.

The front seats are electrically adjustable with lumbar and driver memory.

There are plenty of places in which to put your everyday bits and pieces (including a decent storage bin/arm-rest), as well as charging points, including two USB ports, for your devices.

Need somewhere to put a cold beverage, mate? There are two cup-holders between driver and front-seat passenger, two in the fold-down centre arm-rest for the back-seat passengers, and bottle holders in all doors.

Back-seat passengers also get air vents, climate control, mesh seat-back pockets and grab handles. 

There is a 495-litre cargo space when the rear seats are in use, but that increases to 1495 litres when those seats – 40:20:40 split folding – are stowed away in the floor.

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 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 Audi A4 all road 40 TDI quattro S Tronic has a 2.0-litre, four-cylinder turbo-diesel engine, producing 140kw at 3800-4200rpm and 400Nm at 1750-3000rpm.

It has a seven-speed S tronic automatic transmission and all wheel drive.

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.

It has claimed fuel consumption of 5.2L/100km (combined), but we recorded actual fuel consumption on test of 8.4L/100km – driving in soft sand likely negatively impacted that figure.

It has a 61-litre fuel tank.

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.

For a bloke who spends a lot of time in big, tall and bulky 4WDs, I felt like I was driving a go-kart. It’s that low, but it’s also that much fun – and it’s a very different driving experience to what I’m used to.

The allroad is 4762mm long, 1847mm wide and 1430mm high, and has a listed kerb weight of 1720kg. So relative to the 4WDs I usually steer around, this is light and low slung. It’s more car than SUV, that’s for sure.

Acceleration is rather punchy (the engine and auto are a decent match-up), steering is light but precise, and you can cycle through drive modes (efficiency, comfort, auto etc) to set up vehicle characteristics to suit your driving style and conditions.

The quattro all-wheel drive system helps to keep the allroad planted and composed at all times. 

Ride is on the sharpish side of firm and you do tend to feel every irregularity in the road surface – it is long and low and on low-profile rubber afterall.

The virtual cockpit plus – a 12.3-inch high-resolution colour display – offers a comprehensive read on all things to do with the allroad.

Throw around your superlative of choice – “sporty” and “dynamic” fit this allroad well – but I’m loathe to gush about its on-road performance much more than that because I reckon if any motoring journos are reading this – many of whom spend the lion’s share of their time swanning about in sports cars – they would have already choke-spat out their dirty chai with surprise by now.

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 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.

This Audi has a three-year/unlimited km warranty. Service intervals are recommended every 12 months or 15,000 km, whichever comes 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.
