What's the difference?
When the BMW iX first showed up a few years ago, it was a promising look at what BMW seemed capable of when it comes to electric cars.
While mildly flawed, the iX was fast, comfortable and felt properly premium. Now it’s had a decent update, with the iX xDrive45 M Sport here to replace the former entry-level xDrive 40.
BMW claims among other mechanical and tech updates a power increase of 25 per cent, a 30 per cent greater energy content for the battery, a 38 per cent increase in driving range and a 17 per cent faster charging rate.
But in the time since the iX launched, there have been big strides in the premium electric SUV space, including new arrivals from European opposition like the Polestar 3; even a new American in the form of the Cadillac Lyriq.
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.
If anyone was worried that it would be too late to get a decent bit of value out of an entry-level iX, there's reassuring news.
With more power, range and features added to the model and the cost remaining close to its former sticker price, the iX has held up well despite now existing in a more competitive environment.
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.

The iX was a bit divisive upon its original launch, because it was one of the early adopters of BMW’s current ‘big grille’ era.
The good news for the iX is that many have adjusted their expectations on that front and it now feels pretty well at home in the brand’s line-up.
The addition of the 'Iconic Glow' grille surround might be a step too far for some, but overall the iX has aged well and its exterior design hasn’t changed much because of that.
The adaptive LED headlights have new DRL elements, and the M Sport pack is now standard, but if you were only casually familiar with the iX you’d have to be looking closely to spot the update.
The new colour palette for the iX also includes the pictured 'Arctic Race Blue metallic', though I’m personally a fan of the iX in all black, giving it a more monolithic look.
Inside, it’s a similar story - what was once perhaps ahead of its time is now the expectation in an electric SUV. Minimalism in terms of physical controls, but plenty of space.
Helping the feeling of spaciousness is the now-standard panoramic sunroof, though a lack of physical shade is one of the iX’s few interior let-downs. Instead, it can electrochromatically ‘shade’, which still lets in plenty of light.
At night, ambient lighting joins the glow of the iX’s rather large 14.9-inch multimedia touchscreen and 12.3-inch driver display.
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 space on offer in both rows of the iX is a huge plus, and it might even be enough to make you look past some of the small downsides to the electric Bimmer’s interior.
The iX’s clever two-level central console has the phone charger pad and drinks holders down out of the way and means you can put distractions (phone) and your tall bottles out of the way. There's a slot above for your phone to sit upright with a gap under for charging, too.
The storage bin under the armrest also has plenty of space as well as a little shelf for smaller items you don't want to go hunting for, but the iX’s control panel and dial are still reflective and, at certain times of the day, this means distracting light getting in your eyes.
Speaking of distracting, I have found BMW’s multimedia software to be less intuitive and more complicated with each major update, and ‘OS 8.5’ is no different. At this point, using the brand’s touchscreen feels like operating an iPad on the move, with dozens of menu tiles to sort through.
But back to the physical space that is the iX’s interior - the big EV makes a lot of sense as a family car, especially if your kids are old enough to appreciate (and keep clean) the fit and finish.
Not only does the drive have a nicely adjustable and comfortable sports seat thanks to the M Sport pack, there's also heating and a massage function.
The front passenger gets the same, and the second row is borderline palatial. There's heaps of kneeroom, headroom, and even space under the front seats at their lowest setting to slot your feet.
The four-zone climate controls mean arguments are avoided, there is of course a central armrest, though even with it folded up and a person in the centre there's enough room in the back to be comfortable.
Behind that, the iX’s 500 litres of boot space could probably be expanded but at the expense of rear legroom, so it's acceptable. There is space under the floor for cables, but no space saver spare, just a repair kit.
There's a switch that allows you to fold the seats down from the tailgate, but you can also manually fold the middle seat for a 40/20/40 split rather than the more expected 60/40.
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 sole entry-grade iX is the xDrive45 M Sport, which brings with it more than the original base xDrive40, but also a price a few thousand dollars higher.
It starts from $142,900 but can quickly become much more expensive when you start ticking options boxes. But in this market segment, it's not that unusual, especially considering recent arrivals like the Polestar 3.
Given it’s only a little more expensive than before, the extra kit and higher grade that now forms the iX entry-point is impressive.
The 'M Sport' pack is now standard as the name suggests, plus there’s M trim inside like the steering wheel, the M seats and silver design highlights.
The LED lights are now adaptive and the glowing grille surround has also been added.
There’s also now a panoramic glass roof as standard, rather than an option, plus the steering wheel is heated and there’s now a tyre pressure monitor.
Aside from that, there’s plenty that carries over, like the wireless phone charging, wireless Android Auto and Apple CarPlay, 18-speaker surround sound by Harman Kardon, four-zone climate control and heated front seats.
There’s also an 'Executive Pack' which adds some comfort features like soft-close doors, privacy glass and front seat ventilation with rear seat heating. That one’s $6500.
Then there’s active steering, which brings the rear wheels into play for more manoeuvrability and stability for $3000.
Adaptive air suspension is $4000, while the most expensive option is a 30-speaker Bowers & Wilkins ‘Diamond’ surround sound system for $9500.
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 iX has, as the xDrive part of its name would suggest, a dual-motor electric set-up with all-wheel drive.
Power and torque now total 300kW and 700Nm for the system in the xDrive45 M Sport, up from the 240kW and 630Nm on offer in the outgoing xDrive40.
BMW says the iX is now good to hit 100km/h from a standstill in 5.1 seconds, with its claimed top speed a nice, rounded 200km/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 iX’s 94.8kWh battery allows a range up to 522km, but relatively low efficiency because of the size and weight.
Its 20kWh/100km is on the higher side of power use for cars around this size and this is part of the reason its huge battery capacity results in a fairly average driving range.
Maximum power input for DC fast charging is, however, up from 150kW to 175kW with the update, which is good news for those long drives.
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 BMW iX was a relatively early entry into the catalogue of electric cars I’ve driven and because of that it had a couple of (in hindsight) unfair criticisms levelled at it.
For a start, it felt heavier than expected and its ride quality didn’t feel up to BMW’s standards - both things that plenty of electric SUVs have struggled with since.
But its drivetrain, design, and interior all impressed, aside from perhaps some of the aforementioned interior reflections.
Now years on, and the iX has aged well.
Some of the mechanicals and suspension also copped a tweak along with the entry iX now being a more powerful ‘45’. The result is a big electric SUV that holds up better than I remember.
‘Smooth’ is the key word that comes to mind in regards to a lot of the iX’s characteristics. While it’s still not perfect and feels heavy, the iX rides well in comparison to many SUVs on the market, including some of its close rivals.
Perhaps key to this is the fact its standard 21-inch wheels leave plenty of tyre to help the suspension soak up sharp edges on bumps, while we’re sure BMW’s handling engineers have learned more about getting the best out of a big, heavy electric vehicle in the last couple of years.
Road noise is well-muted as a result, and the shape of the iX doesn’t seem to lend itself to excessive wind noise. Even when you’re getting rather quick.
Despite being a 2525kg beast, its 5.1-second sprint to 100km/h is in the muscle car realm - the last of Holden’s V8 Commodores would do about that, for reference.
Its acceleration is also nicely progressive, rather than giving you an almighty but unnecessary jolt of torque right as you put your foot down. But once there’s traction and you’re rolling, the xDrive45 is impressive.
Meanwhile, its cornering and braking still reveal the heft behind the iX, it’s not something you can chuck around like a go-kart, but that’s also not really its area.
Anyone familiar with BMW’s steering characteristics will find the slightly higher force required for its weight (and thickness of the steering wheel rim) standard, though it’s still unnecessarily on the heavier side.
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 BMW iX holds a five-star ANCAP rating, which it earned under slightly more lenient testing back in 2021.
Seven airbags, auto emergency braking with cyclist and pedestrian detection up to 80km/h, lane-assist, rear-cross traffic alert and intersection assist, plus a surround view parking camera all help immensely.
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.
BMW offers a five-year/unlimited kilometre warranty with an eight-year/160,000km warranty on the battery.
BMW servicing takes place as needed rather than on a schedule, meaning you’ll be alerted via the car or app when a service is required in the near future.
For the iX a six-year all-inclusive service pack costs $3475, regardless of how many km you drive.
BMW has 54 servicing dealers listed in Australia, with each capital city covered and many more locations in the eastern states.
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.
