Audi S4 vs Denza B5

What's the difference?

The S4 and S5 range continues to represent a great formula for performance you can live with every day. They're arguably the sweetest balance Audi produces, actually. All come fantastically equipped, with cabins that feel truly special, and we’re lucky they can be had in a choice of five bodystyles.  

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 S4 sedan and Avant have scored the bulk of design updates, with all new and recontoured side panels including the sedan’s C-pillar matching what was applied to the A4 earlier this year. 

This is paired with new front and rear facias and lighting for a subtle but extensive rework of the fifth-generation S4’s conservative look. 

The S5 Sportback, Coupe and Cabriolet get S5-specific new lighting and facias, but no sheetmetal changes. As before, the Coupe and Cabriolet ride on a 60mm shorter wheelbase than the Sportback, sedan and Avant.

The S5s also get Matrix LED headlights as standard which do a neat animated sequence when you unlock the car. 

Other visual hallmarks include new S4-specific 19-inch wheels, with S5 stepping up to its own unique 20-inch wheel. The six-piston front brake calipers are appropriately painted red, and there’s S-specific adaptive dampers under there too. All variants aside from the Cabriolet get a lip spoiler on the rear.

On the inside, there’s a new centre console and bigger 10.1-inch multimedia screen, while the Audi Virtual Cockpit driver instrument display now offers a hockey stick-style rev counter in additional to traditional dial layouts.

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 biggest practicality change among the five S4 and S5 variants is their upgrade to the latest version of Audi’s MMI multimedia system, which steps up to a 10.1-inch touchscreen and drops the scroll wheel from the centre console.

It also boasts ten times the computing power of the version it replaces and uses this and an on-board sim card to access Google Earth maps for navigation and Audi Connect Plus that offers driver information such as fuel prices and parking information as well as point of interest search and weather information, plus the ability to make emergency calls and seek roadside assistance.

There’s also a wireless phone charger, but using Apple CarPlay will still require a cord as per Android Auto.

I only drove the S4 Avant and S5 Sportback at their media launch, which are clearly the most practical of the five, but from our experience with the previous versions, each looks after its occupants well in terms of space and storage. Back seat accommodation is clearly not a priority in the Coupe and Cabriolet, but there’s three other variants if that’s what you’re looking for. 

The Cabriolet can open its automatic folding soft top within 15 seconds, at speeds of up to 50 km/h.

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.

Audi has taken an ‘if it ain’t broke’ approach with the mechanicals, with all S4 and S5 models unchanged with this update. So the centrepiece continues to be the single-turbocharged 3.0-litre V6 that produces 260kW and 500Nm, with the latter available from a broad 1370-4500rpm.

The rest of the drivetrain is also unchanged, with the venerable but excellent ZF eight-speed torque converter auto paired with the Quattro all-wheel drive system that can send up to 85 per cent of drive to the rear wheels. 

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.

Official combined fuel figures range from 8.6L1/00km for the S4 sedan to 8.8L/100km for the Avant, Coupe and Sportback, while the heavier Cabriolet steps up to 9.1L/100km. 

All are pretty good considering their performance potential and the size of these cars, plus the fact that they only require 95 RON Premium Unleaded fuel.

All have a 58-litre fuel tank, which should enable a range of at least 637km between fills based on the Cabriolet’s figure.

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 S4 and S5 range were already an excellent balance between everyday comfort and a genuine sporting edge, and nothing has changed with this update.

I spent time behind the wheel of the S4 Avant and S5 Sportback at their media launch, and both managed to deliver the proper Audi luxury experience over some pretty rough rural roads, while always feeling a bit more sporting than a regular A4 or A5. That’s with the Drive Select left in the default mode, but you can shift that sporting personality up a few notches (while scaling back the comfort), by selecting Dynamic mode. 

My preferred means of adjusting their personality is by simply tugging the transmission selector back to activate S mode, which livens up the engine and transmission without stiffening up the suspension. 

Across the five S4 and S5 bodystyles, there is some variance in performance potential, with the S4 sedan and S5 Coupe topping the performance chart with 0-100km/h boasts of 4.7s, with the S5 Sportback trailing them by 0.1s, the S4 Avant by a further 0.1s and the Cabriolet managing a still-fast 5.1s claim.

Another area I consider the S4 and S5s to get just right is their exhaust note. It is adaptive, but there’s nothing synthetic about it, and the generally muted and distinctly V6 burble is always there to remind you that you’re aboard a proper performance model, but not in such a way that it will annoy you, or your neighbours. Polite performance, if you will.

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.

Audi continues to offer a three year, unlimited kilometre warranty, which is in line with BMW but lags behind the five years offered by Mercedes-Benz these days. This also contrasts with the five year norm among mainstream brands, which is punctuated by the seven year warranties of Kia and SsangYong.  

Service intervals are a convenient 12 months/15,000km though, and the same five year ‘Audi Genuine Care Service Plan’ offers capped price servicing for the same $2950 total over five years applies to all S4 and S5 variants. This is only marginally more than the plans offered for regular petrol A4 and A5 variants, so you’re not being stung for the thoroughbred versions.

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.
