BMW IX3 vs BMW X5

What's the difference?

The BMW iX3 is a rarity in the market, a premium-feeling electric model that's not a whole lot dearer than petrol alternatives.

For those happy to trade some of the Tesla Model 3 and Kia EV6 GT's all-paw performance for a luxurious cabin, slick drive and badge cachet, the iX3 M Sport is a very attractive package. Until Audi's Q4 and Q6 e-tron arrive, the iX3 remains basically peerless in this part of the market.

No wonder, then, that BMW is Australia's third most popular electric car brand after Tesla and BYD. The vehicles capture everything the brand promises at a price that looks good on paper and better in the real world.

This is a luxurious prestige five-seater brimming with BMW’s latest design and technology that’s not only practical for weekly family duties but can also embrace spirited driving with the push of a button. A great all-rounder for families that like a sporty edge. 

Now that we've seen the new X3, the current model is already dated. Not that it was a cutting-edge design at launch but there is precious little offensive about this mid-size SUV.

Fussy wheel designs, strange closed in grilles and clashing blue accents aside the iX3 M Sport remains a plenty handsome option as you approach.

Inside the cabin's shapes feel positively conservative next to BMW's latest efforts like the X2 and 7 Series but, in a way, this is no bad thing.

It's also nice that you can tailor this car's appearance to your liking without spending extra, the combination here rocks a nice blue paint with tasteful brown upholstery for a classy look.

You can have Oyster white leather or simple black and the paint colour palette is refined without being restrictive.

The latest front-end design features subtle revisions to BMW’s signature 'kidney' grille theme, highlighted by slimmer matrix LED headlights with chevron-shaped DRLs that incorporate the turn indicators.

There’s also an ‘iconic glow’ function, which illuminates the twin-grilles at night in-sync with the external courtesy lights when approaching and departing the vehicle. Lower front air-intake and tail-light treatments have also been revised.

The dash features a new curved instrument panel. Based on BMW’s latest generation 'iDrive' operating system, it consists of a 12.3-inch driver’s info display and 14.9-inch control display presented across the same seamless glass surface.

The control display’s touchscreen functionality has allowed dash buttons and switches to be minimised.

This new design dash has a blend of synthetic leather trim and dark brown/high-gloss woodgrain surfaces, along with new LED ambient lighting and gear-selector design.

The rear seat is sumptuous and spacious, even for someone my height (186cm). There’s ample knee and headroom and it can seat three kids in comfort, but for adult passengers wanting that 'business class' feel it would be ideal for two.

My only criticism of the new instrument display is that with more than 30 applications displayed on the expansive control screen, it can be distracting at times trying to visually locate and operate these functions while driving.

And, depending on sun angle, there were also complaints from different front seat passengers on different days about blinding glare caused by the dash’s high-gloss woodgrain inserts. Fortunately, the driver is unaffected by these reflections.

The BMW X3 was developed with family buyers in mind and that has paid dividends because it has an extremely practical cabin with lots of thoughtful storage.

Each of the four doors has a bottle holder and generously-sized pocked for extra storage. There are two cup-holders in the centre with a wireless charging pad, secure spot for the key fob and USB port in easy reach. You can slide a roller cover down to hide valuables.

Key driving controls are smartly grouped together around the iX3's unconventional gear selector. Here, you'll find the start/stop button along with hard switches for drive mode selection, stability control and exterior cameras.

Right next door is where the rotary 'iDrive' controller lives with yet more physical shortcut buttons. Including the extra option to easily interact with the multimedia system on the move is a refreshing delight that you don't see in so many touchscreen-heavy EVs. There's also a physical stack for HVAC and seat heating controls.

The 12.3-inch touchscreen is responsive and bright with BMW's slightly older system having a more conventional appearance than the latest software in the iX2. Apple CarPlay and Android Auto are wireless and still work flawlessly.

If there are some negatives, they would be some build-quality niggles. On the whole the materials are high quality and the car is well screwed together but the indicator stalks feel decidedly flimsy compared to BMWs of old and I noticed a rattle from the parcel shelf on the road.

The eight-way power adjust seats with tilt and under-leg extension are classic BMW, being sporty enough to hold you in but with enough padding to stay comfy. Though we will knock this car down for lacking power lumbar adjust.

Those in the back will be plenty comfortable even if they're taller than 180cm with ample head, leg and toe-room. There doesn't appear to be a major compromise to the floor height despite BMW stacking 10 lithium-ion modules beneath.

Vision out is excellent with an expansive glasshouse and full-length sunroof.

Amenities include two USB-C charge points, a third climate zone, fold-out armrest with pop-up cup holders and generous storage in the doors.

Fitting child seats should be pretty simple with doors that open wide, two sets of ISOFIX ports (that you can't lose the covers of) and three prominent top tether anchors in the recline-adjustable backrest.

The boot is large with 510L of space at a minimum that expands to 1560L if you fold the 40/20/40 split backrest flat. There's a sense of solidity in that process, too, with sturdy levers and components.

So sturdy that the retractable luggage cover is quite difficult to remove, especially for shorter owners. Other niceties include a single shopping bag hook, LED lighting and 12-volt socket in the back.

No BMW X3 comes with a spare tyre so that should come as no surprise. The iX3 instead has a tyre repair kit. There is underfloor storage in the iX3, though, which is the perfect place to store both charging cables — Mode 2 and 3 — that are included.

With its 2165kg kerb weight and maximum allowable weight of 2885kg, our test vehicle can legally carry up to 720kg.

That should be ample for five adults (even better for kids) and their luggage, of which up to 100kg can be carried on the roof rails using a rack or roof box (both in BMW's accessory range).

Powered upper and lower tailgates provide good access to the luggage area, which is carpeted and equipped with a roll-out privacy screen, load securing hooks, a 12-volt accessory outlet and a first-aid kit stored behind a removable side panel.

The space-saver spare and tools are stored below the hinged load floor, so all luggage must be removed to access them.

Internal luggage space with the rear seat upright is 650 litres (0.65 cubic metres) which expands to 1870 litres (1.87 cubic metres) with the rear seat folded flat.

A useful load-carrying feature when the rear seat’s backrest is upright is a hinged centre section that folds forward and flat to carry long and narrow items.

These can stretch all the way from the tailgate to the dash if need be, which could be handy for carting anything from skis to home hardware purchases (firmly secured, of course).

It’s also rated to tow up to an impressive 3500kg of braked trailer, which matches the class benchmark for one-tonne utes.

However, given that tow-ball download (TBD) is usually around 10 per cent of trailer weight, the X5’s maximum TBD rating of only 140kg could be a challenge if 3500kg towing is required.

Front of cabin storage includes a big bottle-holder and bin in each front door, a glove box and on the right-hand side of the dash a pull-out driver’s bin, both of which are felt-lined.

The centre console, in addition to its wireless phone-charging pad, USB-A port and 12-volt outlet, has two small-bottle/cupholders up front and a large box at the rear, housing a USB-C port and topped by a padded dual 'brochure fold' lid that double as an elbow-rest for driver and front passenger.

Rear seat storage includes a large-bottle holder and bin in each door and pockets on each front seat backrest. The rear of the centre console has two storage nooks for small items in addition to its air-vents, two USB-C ports and a 12-volt outlet. There’s also a handy tablet-mount and USB-C port on each front seat backrest, which is great for long trips.

Folding down the rear seat’s centre armrest reveals two pop-out small-bottle/cupholders. And under its hinged lid is a hidden felt-lined compartment that’s ideal for storing slim screened devices away from prying eyes.

Our test vehicle, to use its full name, is the X5 xDrive 40i M Sport. That breaks down to xDrive (intelligent all-wheel drive) and 40i (3.0L turbo in-line petrol six) with eight-speed automatic transmission.

M Sport denotes a package that's included as standard equipment which contains desirable goodies like enormous multi-piston M Sport brakes/adaptive suspension/aerodynamics, M leather-rimmed steering wheel, high-gloss black roof-rails and more.

All up, the list price is $138,900. However, our example has an optional ‘Enhancement Package’ which for another $6000 adds your choice of selected 22-inch alloy wheels (fitted with 275/35 R22 Continental tyres on ours), a tyre pressure monitoring system, metallic paint ('Skyscraper Grey' on ours), Harman Kardon 16-speaker surround-sound audio and 'Crafted Clarity' glass application (glass-handled shifter).

And this is on top of many standard features including three-zone climate control, automatic two-piece tailgate, digital radio, a head-up driver display, adaptive LED headlights with high beam assist, a panoramic full-length sunroof, wireless Apple/Android integration, 'Verino' quilted synthetic leather upholstery, numerous USB ports/12v outlets and more. However, there’s only a space-saver spare.

Numerous options include self-levelling air suspension, 'Merino' leather upholstery, active seat ventilation and massage functions, thermo-adjustable cupholders, LED-illuminated ‘sky lounge’ panoramic glass sunroof and Bowers & Wilkins premium surround sound to name a few.

In this case there isn't much under the bonnet except for electric gubbins. The single electric motor – that uses no rare earth materials – resides at the back and generates 210kW/400Nm.

Those outputs are fairly close to a petrol X3 30i, though of course this model is rear-drive only.

Thanks to the rapid response of electric motors, the iX3 M Sport can sprint from 0-100km/h in 6.8 seconds (claimed).

BMW has chosen to give the iX3 a long-travel progressive throttle pedal that makes grunt easy to meter out. However, the regenerative braking could do with a little more refinement.

There are two settings, 'D' — just like letting off the throttle in a combustion car — and 'B' which is quite strong. The blending between regenerative and physical caliper-on-rotor braking is vague, though, which can make low-speed moves a bit jerky.

The X5 xDrive40i is powered by BMW’s legendary 3.0-litre DOHC 24-valve in-line six with state-of-the-art technology.

This includes twin-scroll turbocharging, variable valve/camshaft timing and 48-volt mild hybrid technology (delivering up to 9.0kW and 200Nm) using an electric motor integrated with the transmission.

The combined effect is optimised power and throttle response (0-100km/h in 5.4 secs) with minimal fuel consumption and Euro 6d emissions.

It produces 280kW between 5200-6250rpm and 520Nm of torque (this can reach 540Nm with hybrid input) across a remarkably wide and flat peak torque band between 1850-5000rpm, which showcases its flexibility. There’s also auto start-stop and selectable drive modes.

This is paired with BMW’s smooth and sharp-shifting eight-speed torque converter automatic, which combines the best characteristics of a dual-clutch and traditional torque converter transmission.

There’s overdrive on the seventh and eighth gears to optimise fuel economy and the choice of rapid manual-shifting using the steering wheel paddles.

Power reaches its wide tyres through the xDrive intelligent all-wheel drive system, which actively varies the engine’s torque distribution between the front and rear wheels to optimise traction at all times.

BMW’s ‘Efficient Dynamics’ also includes brake energy regeneration with recuperation display and many other standard features to enhance driving safety and efficiency.

The iX3 M Sport's WLTP rating is a respectable but not groundbreaking 461km on the combined cycle. The reality is a little bleaker, our test car displaying 316km on its digital instruments at 100 per cent charge.

Going against what you might expect for an electric car, the iX3 was not very efficient in town, we initially saw 24kWh/100km on the read-out which is quite high.

It is better suited to a longer, steady-state run. Our regular 200km country and suburban test loop dropped the consumption to 18kWh/100km for a real-world driving range of 411km.

When it's time to bring the charge levels back up the iX3 will take on AC electricity at 11kW, for flat to full in seven and a half hours.

Public fast-charging caps out at 150kW (DC) though averages to 104kW over a 10-80 per cent session. This should take 21 minutes, says BMW.

We only observed a maximum of 101kW on a DC charger though the pylon did not appear to be performing at full energy with other vehicles having similar issues.

BMW claims combined average (WLTP) fuel consumption of 9.9-8.5L/100km. Our 415km test comprised a mix of suburban and highway driving and when we stopped to refuel the dash display was showing 10.2L/100km which was line-ball with our own 10.6L/100km figure, calculated from fuel bowser and tripmeter readings.

So, based on our figures, you could expect a realistic driving range of around 780km from its 83-litre tank using standard 91-octane petrol.

Despite no saucy straight-six, V8 or twin-cam four-cylinder there is an inherent 'BMW-ness' in the iX3 M Sport. The way it steers, accelerates and rides all match the brand's DNA.

It is not a plush SUV, with some firmness to the suspension even in Comfort mode on the adaptive dampers — this may have something to do with BMW's 40PSI front and 45PSI rear tyre pressure recommendations — but without ever being crashy.

Build up a little more speed, beyond 60km/h for example, and the body settles nicely with a solid, assured stance.

There's no evidence of suspension noise and road noise is very well insulated as well, even without the up-spec M Sport Pro's acoustically insulated glass. 

The steering is light in Comfort mode which makes it ideal for urban driving. It also has three turns lock-to-lock which is a lot for a sporty-ish BMW, however that is largely down to the improved steering angle. Without an engine or AWD system, the iX3 has a great turning circle of just 12.1 metres.

Moving things up a notch into Sport adds extra weight to the steering which helps judge the grip on good roads, which is pretty decent from the 245/45R19 Yokohama Advan Sport V107 tyres.

When you approach the limit, the iX3 is very secure but significant mid-corner bumps can unsettle the car, bringing its 2180kg tare weight (a 325kg penalty over the xDrive20i) sharply into focus. Pull it back a touch, though, and the iX3 M Sport is plenty rewarding on a country road.

Mostly, the iX3 is a refreshingly natural electric car out on the road. You could put anyone in the driver's seat and they'd be smooth just like in a combustion car.

It’s supremely comfortable, with front bucket seats that offer powered-adjustment of height, reach and backrest angle along with side bolsters that can tighten their grip of your upper torso.

There’s also two-way lumbar support, that adjusts not only how far it pushes your spine forward but also allows that pressure point to be raised or lowered.

Combined with its power-adjustable leather-rimmed steering wheel, it would be hard not to find a comfortable driving position.

Eyelines to all mirrors are good and over-shoulder blind-spots are minimal. Front and rear occupants can talk without raised voices thanks to low engine, wind and tyre noise at highway speeds.

As you’d expect, it has high build quality and a tangibly solid feel as though it was machined from a single block of steel, from the satisfying thuds of its closing doors to the absence of shudders or rattles on a variety of roads.

It also has two personalities, which can be switched in an instant. In 'Comfort' mode it will happily cruise around city and suburbs as a mild-mannered family car, fulfilling daily duties like work commutes, school drop-offs and pick-ups, supermarket shopping and the like.

However, flick the drive mode to 'Sport Plus' and you awaken, well, if not ‘the ultimate driving machine’ then something close.

Its optimised drivetrain and handling settings feel more like a sports sedan than a family car, which can turn any winding mountain road into an engaging experience.

It has impressive reserves of cornering grip and braking force, combined with sparkling engine response and fast sequential manual-shifting at your fingertips.

It feels impressively agile, with all-round response that belies its 2.0-tonne-plus kerb weight, backed by a symphony of sounds from its sublime in-line six.

Five-star ANCAP (awarded in 2018) includes front and side airbags for driver and front passenger, plus head airbags for front and rear seats.

The comprehensive 'Driver Assistant Professional' active safety menu includes AEB (city, interurban and vulnerable road user) and a multitude of others.

It also has 'Parking Assist Professional' and for young families there are ISOFIX child seat anchorages on the two outer rear seating positions and top-tethers for all three.

The iX3 M Sport is now covered by a five-year/unlimited kilometre warranty in Australia.

Servicing is due on a conditional basis with the multimedia system prompting the owner when to visit a dealer.

BMW offers serviced packages for electric vehicles that last six years/unlimited kilometres, with the iX3's pack costing a reasonable $2325 over that time.

BMW covers the X5 with a five year/unlimited km warranty and offers several service plans to suit different budgets and requirements.

For example, the 'Service Inclusive Basic' package covers all scheduled services over five years/80,000km for a total of $3450, or an average of $690 per year.
