Denza B5 vs BMW M3

What's the difference?

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.

Long live the mighty wagon. The BMW M3 Touring is treat to look at, and an even bigger treat to drive.

If you want one, act fast. We waited a long time for a wagon-shaped M3, and with electrification increasing in the automotive industry, this will likely be your last chance.

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.

It looks spectacular, this M3 Touring, and even more so given a) wagons are so rare, and b) proper low-riding performance wagons with massive alloys are even rarer.

That said, I expect it will be polarising – and possibly too shouty for some – but I've got to say, I like it.

I’ve seen it described elsewhere as a bit of a sleeper, but for mine, you’d need painted-on eyes to not see there’s plenty going on with the Touring, especially one finished in the same Frozen Black paint as our test car.

It is at once sleek and swept back, and bulging and aggressive, especially at the flared wheel arches and fat exhausts poking from its diffuser-filled rump.

Inside, it’s mostly business as BMW usual, though with more carbon-fibre elements — our vehicle was equipped with the M Carbon Experience pack — but snug-fitting seats aside, it’s a premium, if performance-focused, place to spend time.

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.

A performance-focused wagon is still a wagon, right? And that means there is oodles of space in the boot, though the seating choices in our test cars made the front seats less comfortable than they could, and should, be.

But first, the boot. The M3 Touring is a 4.8m-long wagon, which pays dividends when it comes to cargo. BMW says you'll find a minimum 500L of storage space, which grows to 1510L with the rear seat folded.

In the back, you’ll find seating for three, with the requisite ISOFIX attachment points, and with enough head and leg room to get comfortable.

But those carbon front seats are an option I wouldn’t be springing for. They arrive carved out of the rock-hard material, though with big holes throughout to reduce their overall weight, and they’re not only challenging to climb in and out of, but they’re awkward and hard to sit behind.

Stick with the regular seats and both rows will be happier.

The BMW M3 Touring lists at $180,100, which isn’t chump change, and positions the wagon body shape a fair way above a regular M3 sedan.

That’s before on-road costs, of course. According to BMW’s website, putting an M3 Touring on the road in NSW will be more like $194,039 — before you start ticking option boxes.

The 'M Carbon Experience' adds $17,500, and reduces overall weight by close to 10kg through carbon bucket seats, and adds more visible carbon and even more possible headroom to fit a helmet

The 'M Carbon ceramic brakes' add another $16,500, and while there are plenty of free paint colours, you can pay up to $7000 for the 'Frozen White' paintwork.

Our test car was finished in 'Frozen Black', a bargain at $5K.

Elsewhere, there is plenty of equipment on a stacked standard features list. 

That includes staggered 19- and 20-inch alloys, BMW’s digital 'Laserlight' headlights, and an automatic boot.

Inside, there’s a 'BMW Live Cockpit' with a 12.3-inch instrument display, a 14.9-inch central screen, a head-up display, wireless device charging, Apple CarPlay and Android Auto and a premium Harman Kardon surround sound stereo.

You also get three-zone climate, leather seats, an 'Active M Differential' and 'Adaptive M Suspension', and seat heating up front.

Oh, and there is lots — lots — of performance, but we’ll come back to that shortly.

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 M3 Touring’s engine might well be one of the best in the business – a hard-charging 3.0-litre twin-turbo-petrol inline six-cylinder engine that produces a sizeable 375kW and 650Nm.

That power is sent to all four wheels via BMW’s 'M xDrive' with Active M Differential, producing a sprint to 100km/h of just 3.6 seconds.

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.

Officially, you should see a claimed 10.4L/100km on the combined cycle, but as is often the case in cars with engines that tempt you to be aggressive with the accelerator, the reality can be a little different.

We saw more like 16.4L/100km, but in the big bruiser’s defence, we spent a lot of time in city and suburbs, and a lot more time standing on the accelerator.

The M3 Touring is fitted with a 59-litre tank, and will only accept 98RON premium fuel.

Range is close to 570km using the official consumption figure and around 360km using our real-world number.

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.

In a word? Delightful.

Don’t get me wrong, it’s not the easiest car in the world to daily drive. The carbon-fibre seats fitted to ours, for example, made getting in and out a slightly embarrassing challenge, and there’s a surging eagerness to the delivery of power that makes you look a little like you're showing off.

But the adaptive suspension serves up a far more comfortable ride than you might be expecting (more comfortable, in fact, than lesser, cheaper M models), making tootling around town easier and less chiropractic than I was expecting.

But it’s away from the city, with its traffic and red lights, that owning the M3 Touring becomes a delight, from its potent and punchy powertrain to the thrum of its exhaust, and the EV-like immediacy of its power delivery.

This is a driver’s wagon, there’s no doubt about it, with proper seatback-pushing acceleration, direct and confident steering and enough body stiffening and bracing that you really would have no idea you’re driving a wagon when cornering.

Engage its sportiest settings, and disengage its electronic nanny systems, and you can even set to work judging your drifting skills, courtesy of the (as yet untested, honestly) 'M Drift Analyser'.

A family car like few others, then. That you can also take it to Bunnings and throw some sleepers in the back is just a very welcome bonus.

Neither the M3 or M3 Touring have been independently crash tested to date, but it’s worth pointing out the 3 Series and 4 Series received maximum five-star scores from Euro NCAP.

Standard safety kit includes AEB with pedestrian detection, active lane keeping assist, blind spot monitoring, adaptive cruise control and rear cross-traffic alert.

You’ll also find six airbags on board.

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.

The BMW M3 Touring is covered by a five-year, unlimited kilometre warranty, and servicing is "condition based", in that the vehicle will tell you what maintenance is required, and when.

You can prepay your service costs at the time of purchase for all BMW vehicles, covering the first five years of ownership.
