Denza B5 vs BMW IX1

What's the difference?

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.

BMW is a true EV pioneer, as the 2014 i3 and subsequent models prove. There’s never been one that we didn’t like. The only problem was that all were expensive. And at times, prohibitively so.

Astoundingly, the iX1 breaks that cycle, comparatively speaking, while impressing us with its design, quality, packaging, dynamics and equipment levels.

As it stands, the xDrive30 is one of the most convincing and best-value medium-sized luxury SUV EVs on the market right now.

Who’d have thought it from a BMW?

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.

Arguably the prettiest new BMW SUV you can buy today, the well-proportioned iX1 is nearly impossible to spot over its almost-identical ICE (U11) X1 siblings.

Besides the badging, look for some blue trim bits and pieces inside and out, along with additional digital touchpoints inside.

And while both ride on the same all-new platform that’s resulted in a substantially larger body compared to previous X1 generations, the EV version seems a bit more slammed.

Dimensionally, the iX1 mirrors today’s X1 at 4500mm long and 1845mm wide, and still sits on the same 2692mm wheelbase, but is 26mm shorter at 1616mm tall and offers 35mm less ground clearance at 170mm.

Result? These plus a bunch of aero enhancements mean the slipperiest iX1 manages a Cd of just 0.26, according to BMW.

And, inevitably, the extra size equals more space inside.

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.

BMW also says the iX1’s cabin is almost as roomy in some ways as the larger X3.

Large doors allow for easy entry and egress, onto sumptuous front seats that provide exceptional comfort and support even on longer journeys.

Surrounded by an expansive feeling of space, the interior feels light and airy, as well as fresh, inviting and premium looking – something previous-gen X1s were rarely accused of being.

We’re talking on-brand stuff here, beginning with the excellent driving position, ahead of a crisp and attractive dash that’s pleasing to behold. Push-button starting and a small toggle lever operates the transmission.

An ever-so-slightly curved (towards the driver in the best-BMW old-school way) rectangular binnacle houses two digital displays – a 10.25-inch one ahead of the driver offering an array of configurable electronic dials, as well as a 10.7-inch multimedia touchscreen.

BMW pioneered the multimedia controller more than 20 years ago with iDrive, and this descendent of that system reveals all that expertise gained by being intuitive to operate and quick to respond to commands once familiarised. Which shouldn’t take too long.

It’s all very-EV centric, as the industry inexorably moves to total electrification, but there were a couple of voice-command errors in the iX1, revealing that such systems are still far from perfect. BMW does provide audio volume and climate hard buttons, thankfully, so the basics are looked after.

Speaking of which, the iX1 offers decent levels of vision out, superb ventilation and ample storage in the doors, on the dash and between the front seats. And, as we’ve noted previously in BMWs, the upright smartphone charger is a clever idea. Keeps it in position and is handy to glance at.

Out back, backrest comfort and support is A-OK, and even with the optional sunroof, our test iX1 provided sufficient space for taller bodies, while expected items like ventilation grilles, USB ports and cupholders are fitted.

Note that, though the 40/20/40-split backrests recline slightly, they do not slide as per in the ICE X1, as this is a desirable option.

Nor is the cargo capacity as good in the iX1, due to the inevitable space demanded by that rear-axle-mounted electric motor and battery pack. For the record, ranges from 490 litres to 1495L instead of 540-1527L. Plus, there’s no spare tyre, with just a tyre repair kit fitted.

These aside, the iX1’s spacious and inviting interior remains one of the compact SUV segment’s best.

For now, only a single iX1 grade is available, dubbed xDrive30, starting from $84,900 (all prices are before on-road costs).

Most buyers seem to be choosing the no-cost-extra racier 'M Sport' pack over the more-conservatively presented 'xLine'.

Both come complete with double-the-usual AC charging capability (22kW), twin-motor all-wheel drive, a 67kWh battery, variable-ratio steering and adaptive dampers as standard.

In contrast, the Mercedes EQB 350 4Matic equivalent starts from over $107,000 (though a less-expensive single-motor front-drive version comes in from nearly $89,000), and both with a slower 11kW charger. Genesis’ advanced GV60, meanwhile, kicks off from nearly $108K.

We cannot remember BMW ever going so hard on comparative value in Australia, though how it responds to the sensational (though admittedly smaller) Volvo EX30’s $59,990 ask remains to be seen.

Anyway, the iX1 is no bare-bones special.

Besides the aforementioned twin electric motors, AWD, 22kW AC charger and (non-driver-configurable) adaptive dampers, there are goodies like keyless entry/start, a digital key with ultra-wide-band tech, a 10.7-inch multimedia touchscreen, a digital instrumentation cluster, ‘Hey, BMW!’ voice control, a head-up display, sat-nav with augmented reality view, dual-zone climate control, ‘Veganza’ artificial leather, a reversing camera, digital radio, Apple CarPlay/Android Auto connectivity, wireless phone charging, a powered tailgate, roof rails and 19-inch alloy wheels.

On the safety front, you’ll find driver-assist tech like autonomous emergency braking (AEB), lane-support systems, adaptive cruise control, adaptive LED headlights and automatic parking assist. More on those in the safety section below.

Need more but want to think less? BMW’s new and simplified option packs bundles key features like a panoramic sunroof, metallic paint (normally $1500 on its own), Harman Kardon audio upgrade, lumbar massaging front seats and alternative interior trims in a reasonably-priced $4700 'Enhancement Pack'.

There are several others bundles available, too, as well as a handy 22kW BMW AC Wallbox from $1199, not including installation, that cuts down home-charging from over 33 hours using the regular mains to around 3.5 hours.

And don’t worry, BMW diehards. You can still spend tens of thousands of dollars more via the company’s endlessly extensive options list. The Germans aren’t foolish.

Unlike in the iX3’s Hyundai, Kia or Genesis rivals, which use a pure EV skateboard platform and offer no internal combustion engine (ICE) alternatives on this architecture, there is no V2L Vehicle-to-Load capability. In other words, you cannot charge appliances or power your home in an electrical blackout scenario.

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.

The iX1 boasts BMW’s fifth-generation EV drive system, known as eDrive 5.0 (M170SF).

Being an xDrive30, there are two electric motors fitted – one on each axle to provide all-wheel drive. Both are electrically excited synchronous motor set-ups.

Drive is predominantly to the front wheels via a single-speed reduction gear transmission, unless extra traction is required, in which case the rear motor kicks in to power the back axle.

Combined with the aid of an overboost function, they deliver 230kW of power and 494Nm of torque, for a 0-100km/h sprint time of 5.6 seconds, on the way to a 180km/h top speed.

Tipping the scales at 2010kg, the xDrive30 provides a power-to-weight ratio of 114kW per tonne, which is a healthy number.

Suspension is via MacPherson-style struts up front and an independent three-link design out back.

If you care, towing limits are 1200kg braked and 750kg unbraked, with a 570kg maximum payload.

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.
 

BMW says the xDrive30 consumes an average of 18.3kWh/100km.

On the launch drive program, the vehicle displayed 21.3kWh/100km. That included some spirited highway and mountain-road driving conditions.

Fitted with a 67kWh lithium-ion battery pack with a useable 65kWh, the iX1 offers an ADR 81/02-rated range of 400km.

This means a relatively common 50kW DC public charger with a CCS Combo 2 socket will need about 65 minutes to replenish the battery from 10 to 80 per cent or about half an hour with a 150kW charger.

If neither are available, you'll require about 34 hours to charge to 100 per cent maximum using the normal household powerpoint plug. Or, as mentioned earlier, a 22kW AC Wallbox cuts that down to about 3.5 hours.

Each iX1 includes a three-year subscription with Chargefox.

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.

One of the best things about the iX1 xDrive30 is that it has just enough EV smoothness, refinement and speed to feel special, yet still drives and behaves as a BMW should.

Which hasn't always been the case with previous-gen X1s.

It helps that, from the driver’s seat, everything falls into place: the bracing seats, thoughtfully positioned relative to all controls; and the overall sporty/quality ambience that puts you into the brand mindset.

Select Drive, and the iX1 leaps away sweetly and silently, accompanied by an electric motor whir that's quite pleasing. At speed, acceleration is instant for fast overtaking and there’s plenty more in reserve if you really need to hustle along.

For a 2.0-tonne compact SUV, the steering is remarkably responsive, providing nimble yet secure handling. Maybe it’s all the low-slung weight and near-50:50 weight distribution, but the iX1 displays impressive cornering and road grip. It’s an enjoyable drive.

Initially, novices might find the brakes a bit sudden, but they’re actually pretty progressive once you get used to them, and they feel and stop with a more natural pedal feel than many hybrids we’ve experienced. Again, BMW has tuned the xDrive30 to feel inclusive.   

Speaking of the stoppers, there are no paddle shifters to control the amount of single-pedal off-accelerator braking as per many other EVs, but putting the transmission from ‘D’ to ‘B’ brings a decent level of deceleration if not a full stop – as if you’re lighting resting your foot on the pedal. We’d like the option of a heavier self-braking function, though.

The launch program avoided city roads and heavy traffic, but we still found plenty of bad, pot-holed surfaces to favourably judge the adaptive dampers’ ability to help soak up the bumps.

While not super-soft or supple, the suspension is cushy enough for a comfy ride. And certainly better than many past BMW SUVs.

A bit too much road and tyre noise intrusion aside, the xDrive30 is dynamically very sorted indeed.

Which, when you consider all the other positive aspects of the iX1, you end up with a BMW offering an impressively broad band of capabilities.

It’s rapid, nimble and reactive to driver inputs, as you’d expect an SUV from this brand to be, without the compromise of harshness or discomfort.

What it’s like around town in a peak-hour crawl, or how far you can really get from a fully-charged battery, is something we’ll find out when we can conduct a full road test, so please watch this space.

Until then, as it stands, things are looking promising indeed for the xDrive30. Especially factoring in the value pricing.

ANCAP awarded the X1 petrol versions a five-star rating in 2022, based on the European NCAP result. No separate iX1 figure is as-yet available.

The iX1 comes with many of the latest driver-assist safety tech features, including AEB with day/night pedestrian and cyclist detection. This system is operational from 5.0km/h.

You'll also find front and rear cross-traffic alert, secondary collision avoidance braking, as well as a blind-spot monitor, lane-departure warning and swerve-assist systems, speed assist tech like adaptive cruise control with full-stop/go functionality, stability and traction controls, anti-lock brakes with brake-assist and a drowsy driver alert.

The lane support systems start from 60km/h and the driver monitoring system kicks in from 70km/h.

Along with dual-front airbags, the front-seat occupants have side chest and side pelvis airbag protection, as well as an airbag between them to help mitigate lateral-impact injuries while outboard rear-seat occupants have side head airbags (also called curtain airbags) coverage. The total airbag count is seven.

ISOFIX child-seat latches are fitted to outboard rear seat positions, while a trio of top tethers for straps are included across the back bench.

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.

Last year, BMW introduced a five-year/unlimited kilometre warranty with all its products, finally catching up with the industry warranty average after a protracted period of just a three-year coverage.

While there’s no capped-price servicing, you can pre-purchase a number of service bundles, to help save a bit more money further down the track.

There's a choice of 'Basic' or 'Plus' packages, in four or six-year (both with unlimited kilometre) programs, known as 'Service Inclusive'. They cost $1263/$4784 and $1800/$5784, respectively. 'Plus' covers brake pads/discs and wiper blade rubbers.

Note, however, that roadside assistance remains at three years.

Keep in mind, too, that BMW vehicles have a self-diagnosis feature that varies the service intervals according to how they’re used as well as wear and tear.

Our advice is to keep making an appointment annually or at about every 10,000km, just to be on the safe side.
