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.
BMW has recently launched its fourth-generation (G45) X3 range, which comprises three petrol variants including the entry-level 20 xDrive, mid-grade 30e xDrive PHEV and top-shelf M50 xDrive.
The new trio brings revised powertrains, new exterior and interior styling, increased standard equipment, enhanced technology and an emphasis on the use of sustainable materials.
We recently trialled the five-seater flagship to see if it has the right mix of performance and practicality to maintain the X3’s enduring appeal for Aussie families.
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.
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 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.
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.
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.
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 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.
Our X3 M50 xDrive test vehicle, finished in new 'Dune Grey Metallic', comes standard with a 3.0-litre turbocharged inline six-cylinder petrol engine incorporating 48-volt mild-hybrid technology, plus an eight-speed automatic and permanent all-wheel drive for a list price of $128,900.
You’d expect a high performance prestige vehicle costing six figures would be packed with desirable standard features and the M50 xDrive delivers, starting with big 21-inch 'M' lightweight alloy wheels shod with wide 285/35R21 tyres.
However, there’s no room for a spare (not even a space-saver) so you get a tyre repair kit instead.
The standard equipment list also includes adaptive LED headlights (with matrix high-beam and blue design detailing), a power tailgate, an ‘Iconic Glow’ illuminated kidney grille with M-specific elements, quad exhaust outlets, a panorama full-length (fixed) glass roof, a choice of six premium metallic paint colours and more. The 'M Sport Pro' visual enhancement package is also included.
Step inside and the driver is treated to a head-up display and an elegantly curved digital dash display, which spans about two-thirds of the cabin's width. It seamlessly incorporates a 12.3-inch driver’s instrument display (made from recycled polyester) and 14.9-inch multimedia display controlled by BMW’s latest 'iDrive System 9' software.
Premium audio is provided by a 15-speaker 750-watt Harman Kardon surround sound system, which includes digital radio and wireless Apple/Android connectivity. There’s also wireless phone charging.
The driver gets a thick leather-rimmed and heated 'M Sport' flat-bottom steering wheel and the driver and front passenger are also treated to sumptuous bucket seats with multiple power adjustments and heating/cooling.
Up to three passengers can share the rear bench seat and indulge in the luxury of three-zone automatic climate control, heating for the outer seating positions, privacy glass, roll-up sunshades, two USB-C ports and lots more.
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.
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 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.
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 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.
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 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.
No ANCAP rating as yet but this X3 comes with a long menu of standard safety features including multiple airbags, AEB with pedestrian/cyclist/junction detection, front collision warning with brake intervention, lane-keeping, active cruise control, head-up display with speed sign recognition, front and rear cross-traffic alert, tyre pressure monitoring and lots more.
There are also ISOFIX and top tethers for the two outer rear seating positions.
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.
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.
