BMW X Models vs Denza B5

What's the difference?

This is a highly competent all-rounder, given that it has the comfort and practicality for urban family duties yet with its revered M breeding can produce a level of performance which, in competent hands, could hold its own at a track day where its capabilities could be safely explored.

The Denza B5 Leopard PHEV is an impressive five-seat premium-style 4WD wagon: it’s reasonably nice to drive, it’s comfortable and it’s a capable 4WD and word on the tracks is that a new software update is set to make it even more of an effective off-roader.

It doesn’t offer the level of fuel economy you’d hope for, and there are issues with elements of its driver-assist tech suite – some of which are jarring and over-reactive – but the B5 looks and feels like a premium 4WD and represents decent value for money, especially when cross-shopped against something like a new-generation Prado.

The fourth-gen X3, which has a lighter but stiffer body, shares the same wheelbase as its third-gen predecessor but at 4755mm end-to-end it's 34mm longer and it's 29mm wider.

It’s also 25mm lower, which combined with front and rear track-width increases and adaptive suspension damping to sharpen the handling underlines its sportiness and driver appeal, despite a substantial 2055kg kerb weight.

The new exterior design is characterised by short overhangs, flush door handles, a larger ‘split kidney’ grille, new LED taillights and L-shaped light elements for the LED headlights.

The new interior design is a classy mix of soft-touch materials and high-gloss hard surfaces in tastefully contrasting tones. The seats are upholstered in a new synthetic leather called 'Veganza' ('Espresso Brown' in our example) which according to BMW requires 85 per cent fewer CO2 emissions to produce than genuine leather (which is still available as an extra-cost option).

Combined with subtle use of ‘Magnolia’ fine-wood trim inserts, satin chrome, piano black, blue/red M highlights and slender ambient light-strips, it’s a cabin that exudes opulence.

It’s easy to immediately pick up on the B5’s plethora of design cues: it wears with pride its old-school 4WD influences – not the least of which is its blocky, straight-up-and-down profile – mixed in new-gen looks.

All-round this 4WD wagon might be considered an affectionate homage to the likes of the Toyota Prado (aka 250 Series).

The B5 sports roof rails, a sunroof and 20-inch alloy wheels.

Whatever you see when you look at the B5, at least it’s not generic or boring.

And that non-boring impression continues inside…

The B5’s interior is premium-looking and -feeling and it also features quirky touches, such as the crystal-look buttons including a ruby-red start-stop button, and enough leather-accented surfaces and brushed-metal-type sections to keep you intrigued.

Though the dash may be a confusion of buttons and controls, on- and off-screen, the whole she-bang is superficially impressive.

Case in point: the auto shifter lowers and self-stows away in the centre console when the car is switched off and rises for use when the car is switched on. Neat.

It’s on a par in design terms with rivals, such as the Prado.

This would make a great family weekend escape machine, for which BMW quotes a 645kg payload rating. It’s also rated to tow up to 2500kg of braked trailer, which could pose a challenge given the relatively low 100kg tow-ball download limit (TBD is typically around 10 per cent of trailer weight).

BMW also does not publish a GCM figure (how much it can legally carry and tow at the same time) so we can’t confirm if it can carry its maximum payload while towing its maximum trailer weight.

Even so, the M50 has a useful-sized luggage area which offers up to 570 litres (or 0.57 cubic metres) of load volume with the rear seat upright.

This expands to 1700 litres (or 1.7 cubic metres) with the rear seat folded flat, which can be handy for a multitude of tasks like transporting a mountain bike or hauling home flat-pack furniture.

There’s comfortable space for the driver and front passenger, along with useful storage including large bottle-holders and bins in each front door.

The centre console has two small-bottle/cupholders plus wireless phone-charging and a pair of USB ports. There's also a glove box plus another box at the rear of the console with a padded lid that doubles as an elbow rest.

The rear bench seat is surprisingly spacious, given that I’m 186cm tall and when seated behind the driver’s seat in my position I still have about 40mm of knee clearance, which is optimised by the concave shape of the front seat backrests.

The spacious and airy feel is enhanced by the ‘panorama’ glass roof which spans the full length of the seating area and allows generous headroom even for tall people.  

However, shoulder room is tight for three adults and the centre passenger’s feet must contend with the transmission tunnel, so even though it would be fine for three kids we’d suggest a limit of two adults for longer trips.

Rear passengers get privacy glass and pull-up roller sunshades, large-bottle holders and bins in each door plus net-type pockets and anchorage points for media devices on each front seat backrest. There are also two small-bottle/cupholders in the fold-down centre armrest.

The rear of the centre console has two USB ports, adjustable air-vents plus controls for zone temperature, airflow preferences and seat-heating.

The bench seat features a 40/20/40 split, which allows the centre backrest to fold forward independent of the two outer backrests to allow long loads like snow skis, home hardware etc to be carried if securely fastened.

A power tailgate provides access to the luggage area, which is equipped with a handy 12-volt accessory socket plus load-anchorage points front and rear, extra storage nooks for small items on either side and a retractable roller-type load cover. Overall, this vehicle offers good practicality for family duties.

The B5’s cabin is plush, spacious, and comfortable.

The driver’s seat is eight-way power adjustable (plus four-way adjustable lumbar support), while the front passenger seat is six-way power adjustable.

As mentioned earlier, all seats are Nappa leather-accented.

The B5’s luxury-style interior, also as mentioned, includes nifty touches, such as crystal-look buttons being the most obvious, and an auto shifter auto that stows away in the centre console when the car is switched off and rises, ready for use, when the car is switched on. 

Elsewhere the dash and centre console is, at first, a confusion of buttons and controls, on-screen and off. But you soon get sort of used to all of it.

The second row is a 60:40 split-fold split and it has a flip-down control console rather than a basic centre armrest with cupholders.

The rear cargo area has four tie-down points and volume is listed as 470L (with the second row up and in use) and 1064 litres with the second row stowed away.

The Denza B5 Leopard PHEV is available in two specs: entry-level B5 and top-spec B5 Leopard, which is the subject of this test. The Leopard has a recommended retail price of $79,990 (excluding on-road costs), while the regular B5 is $74,990.

Standard features in the Leopard include a 15.6-inch touchscreen multimedia system (with wireless Apple CarPlay and Android Auto), a 12.3-inch driver instrument cluster, surround-view cameras, hydraulic adaptive suspension, 16 driving modes, and front and rear diff locks.

The Leopard has Nappa leather-accented seats.

The B5 and its bigger stablemate, the B8, mark the debut of Denza’s Dual Mode Off-road (DMO) hybrid 4x4 architecture, consisting of the plug-in hybrid powertrain, which umbrellas a Blade battery, twin electric motors, and turbocharged four-cylinder engine – but more on that later.

Also of note is the fact that this B5’s 31.8kWh battery supports Vehicle-to-Load (V2L) functionality/capability, which means you can power your camping gear (lights, fridge, karaoke juke box etc.).

Eclipse Black paint is standard. Optional paint choices – including Alpine White, Juniper Green, Glacier Blue, Granite Grey and Leopard Gold – each costs an extra $1500 (including an interior colour-scheme and materials to match).

It’s more impressive in the value-for-money stakes than something like the new-generation Toyota Prado, which will set you back upwards of $100,000 for an Altitude or Kakadu spec.

According to BMW, the M50 xDrive features the most powerful inline six-cylinder petrol engine fitted to an M Performance model.

This 3.0-litre unit clearly benefits from BMW’s twin-scroll turbocharging technology, which combined with variable valve timing and an extra 13kW/200Nm from the 48V mild-hybrid technology produces a stomping 293kW of power at 5500rpm and 580Nm of torque at 1900rpm.

It also has a ‘boost’ function, which provides an extra burst of power for short periods when maximum acceleration is required when overtaking etc.

It’s activated by the left paddle-shifter on the steering wheel and automatically optimises transmission/chassis settings to suit. There’s also a drive mode selector, with ‘Sport’ offering the most responsive and engaging experience.

The eight-speed torque converter automatic is a refined and efficient transmission well suited to this full-time all-wheel drive application. Rapid-fire manual shifting is also available using the steering wheel paddles.

The B5 has a 1.5-litre turbocharged four-cylinder petrol engine, a 31.8kWh battery and an electric motor on each axle (front: 200kW/360Nm, rear: 285kW/400Nm) – and that combination all-up produces total outputs of 400kW and 760Nm.

The Leopard has a CVT, low-range 4WD gearing, as well as a front and rear diff lock.

The Denza B5 has 16 selectable drive modes: daily drive modes (Comfort, Eco and Sport), as well as terrain modes (Snow, Sand, Mud, Mountain, Rock, Intelligent, Creep, Wading, Sport+, Custom, Burst, Climbing, Tug-of-War (towing), L Function (low-range 4WD), and Leopard Turn, which is the B5’s equivalent of the Tank Turn, where it brakes the inside rear wheel during tight, low-speed off-road turns, reducing the turning radius, and so enabling the B5 to navigate a particularly tight turn.

BMW claims an official average combined consumption of 8.2L/100km but the dash display was showing 9.9 at the completion of our 210km test, which included a mix of suburban, city and highway travel.

Our own figure, calculated from fuel bowser and tripmeter readings, came in slightly higher again at 10.5L/100km, which given our test vehicle’s two-tonne-plus weight and performance capabilities is still reasonable economy.

So, based on our figures, you could expect a realistic driving range of around 600km from its 65-litre tank, which prefers premium 98 RON petrol.

The 31.8kWh battery provides up to 100km of electric-only driving and supports 100kW DC fast-charging.

Official combined fuel consumption is 3.9L/100km and the B5 runs on regular unleaded fuel (91).

Official fuel consumption is 10.9L/100km when state of charge is lower than 25 per cent.

On this test, I recorded 10.2L/100km.

The B5 has a 83-litre fuel tank so, going by my fuel figures, you could expect a total driving range of about 900km out of a full tank and a full charge.
 

First, the fun stuff. It certainly feels like ‘the ultimate driving machine’ when you slide behind the chunky leather-rimmed flat-bottom steering wheel and hold it in your hands.

The driver’s seat offers not only powered adjustment of backrest and base-cushion rake, but also four-way lumbar support and side-bolsters that can tighten their embrace of your upper torso to contend with high cornering loads.

There’s also manual extension of the base-cushion length for greater thigh support and a big left footrest to brace against, so you could not ask for a more accommodating and purposeful driving position.

The steering is perfectly weighted and the quartet of enormous disc brakes provide ample bite with superb pedal feel. Combined with its adaptive suspension and wide grippy tyres, the X3 is a family car that’s also invigorating to drive, particularly when you select the ‘Sport’ mode.

The enhanced engine response and sharper steering that result (even the instrument panel display changes) make any twisting mountain road an engaging experience, enhanced by an intoxicating exhaust note that only a BMW M six can deliver.

The turbocharged engine offers an unyielding surge of acceleration from well below peak torque at 1900rpm to maximum power at 5500rpm, making BMW’s claim of 0-100km/h in a scant 4.6 seconds sound credible.

You can also manually change gears using the steering wheel paddles, but we found the gearing and shift calibrations so good that we preferred to leave it in auto mode.

However, the X3 M50 has two distinct personalities, as in more relaxed drive modes it’s just as happy serving as practical family transport during the week for grocery shopping, daily school runs and other common tasks.

It’s also a comfortable tourer for family getaways, with long gearing that requires only 1500rpm to cruise at 100km/h where low engine, tyre and wind noise allow highway conversations at lounge room levels.

The B5 Leopard is 4921mm long (with a 2800mm wheelbase), 1970mm wide, 1930mm high. It has a listed kerb weight of 3007kg and a 11.8m turning circle. 

Yep, so it’s not insubstantial. But it doesn’t feel unwieldy to drive.

On road, there’s a lot to like about the B5: it's comfortable, refined and composed and it has such a premium feel about it that it really is a top spot in which to spend a lot of time, on road trips, day-to-day driving or long road trips – it's very impressive.

Denza reckons the B5 is capable of doing the 0-100km/h sprint in 4.8 seconds but, while I did admittedly check out the B5’s impressive acceleration in short bursts, I didn’t try to prove or disprove that 0-100km/h claim.

On dirt tracks the B5’s suspension – double wishbone independent and coil springs – yields a firm and jittery ride over minor irregularities in the track but otherwise it’s mostly controlled

Off-road, the separate body-on-ladder chassis B5 has up its metal sleeve an effective combination of mechanical low-range 4WD on the rear axle, electronic torque vectoring at front, diff locks front and rear, and well-calibrated off-road traction control.

This plug-in hybrid optimises a combination of driver-assist technology – including 16 drive modes with the bulk of those designed for off-road scenarios – and with nicely dialled-in off-road traction control and mechanical diff locks on-board it is formidable in most off-road situations.

In action, all of those modes adjust vehicle systems, throttle, and engine output to give the driver the best chance possible of getting safely through every off-road challenge.

And it does a bloody good job of it. 

The B5 tackled our steep rock-step test with ease there's plenty of torque available and again that off-road traction control system is well calibrated, sharp and precise in its application.

Off-road angles on this vehicle are also on the right side of good and the fact that the Leopard has hydraulic-adjustable suspension to suit each driving mode is also a handy feature because you can maximise those off-road angles – approach, departure and ramp-over – as well as ground clearance.

In fact, you can set ground clearance anywhere between 220mm and 310mm and that means you have greater flexibility in terms of what you can drive, how you can drive, how severe an obstacle you can tackle and how safe you are while doing that.

This plug-in hybrid works through a continuously variable transmission (CVT) and it works well in this vehicle, in this package. It's clever, smooth and seamless in its operation 

Another bonus is the B5’s off-road/360-degree cameras, which actually offer a decent image rather than the muddy, fish-eye view of some other on-board camera systems.

Now for the flaws.

There’s little to no wheel travel; there’s not a lot of stretch to those wheels when the height-adjustable suspension is maxed out at its top point – in Crawl mode – so you are sacrificing that. 

The B5’s tyres (Pirelli Scorpion Elect SUV tyres – 275/55R20) are marketed as “all weather” tyres but they're not suited to four-wheel driving of any great difficulty.

If you’re thinking about using your B5 as an off-road tourer, get rid of the showroom-standard tyres and replace them with more aggressive all-terrains. 

Payload in the Leopard is 490kg (600kg in the standard B5).

In terms of towing capacity: the B5 Leopard is rated to tow 750kg unbraked, and 3000kg braked. GVM is 3497kg, while GCM is 6232kg.

The B5 is a very effective 4WD wagon: smooth and comfortably capable.

There are some issues with the driver-assist tech, but that's mostly limited to its on-road behaviour – it can be intrusive and preemptive in its application – but the driver-assist tech, which relates to off-road performance, is impressive. 

We eagerly await a full-blown software update that will further improve the B5’s off-road efficacy.

The Denza B5 Leopard PHEV has the maximum five-star ANCAP rating from testing in 2025.

As standard, it has 11 airbags (curtain, front, side, knee and centre airbags) and a comprehensive suite of driver-assist tech including AEB, adaptive cruise control, tyre pressure monitoring, a 360-degree around-view camera, as well as front and rear collision warning, and front cross traffic alert.

On a par with more expensive rivals, then.

It comes standard with a five-year, unlimited km warranty.

Scheduled servicing is determined by BMW’s vehicle monitoring system which advises when a service is needed, typically around 12 months/15,000km.

A capped-price servicing package covering five years/80,000km (whichever occurs first) totals $2475, or an average of $495 per service.

The Denza B5 Leopard PHEV is covered by a six-year/150,000km warranty. 

The B5’s 31.8kWh battery has an eight year/160,000km warranty.

The first service is scheduled at six months/3500km; the rest of the servicing appointments are set for every 12 months/20,000km.

Total cost is $3220 (plus GST) via five-year capped-price servicing.

That puts it on a par with more expensive rivals.
