BMW X Models vs BMW X4

What's the difference?

There is little doubt the new X2 represents a vast improvement over the original model. The design alone gives it a lot more presence. 

More interior and boot space also helps widen the SUV’s appeal and the significant tech updates are welcome.

It is on the pricey side and there are a few too many options that should be standard. 

However, the M35i is hard to ignore as a sporty premium crossover, and the iX2 xDrive30 is the sort of electric SUV that should worry Volvo.

They both have their own distinct flavours, so there’s no dud in this line-up. Of course, we will hold final thoughts for the local launch when we can drive all four grades. But until then, it’s a welcome return to form for the X2.

Okay, so the BMW X4 xDrive30i is neither an ass nor an elbow, to be fair, it's more of a bulky shoulder muscle, or two.

I can't say I'll ever love the X4, the idea of it is a bit too weird for me, but I can't help admiring the way it looks and the way it drives.

It's a bit like a sedan on steroids - or an SUV on a diet, depending on your perspective - but that doesn’t take away from the fact that it’s fun to drive, comfortable and retains just enough coolness, and just enough practicality, to make it worthwhile.

The second-gen X2 looks very different to the original from 2018. That first X2 had a squat stance, looked more like a hatchback than an SUV, and the glasshouse appeared as though it had been squished into the body of the car.

The 2024 X2 adopts a similar design philosophy to the X4 and X6 - swoopy, coupe-like roofline and liftback, and bold styling elements at the front and rear.

It has a much more upright, flush front end, freshly designed large kidney grille and an edgy headlight design. There’s flared wheel arches and broad shoulders at the rear, as well as a cool new horizontal tail-light signature.

The X2 has grown in size in a big way. It’s 194mm longer, 21mm wider, and 64mm taller than the outgoing model. That naturally means more space inside, too.

Inside there are big changes. The X2 adopts elements introduced by the excellent iX SUV a couple of years ago. They include the curved display, and a floating arm rest with a control panel. Some of this is also familiar from the X1.

The materials mostly look and feel like they are high quality, and there is an appealing minimalism to the overall design and layout. The chunky sports steering wheel is visually appealing, but it’s a bit too thick in my hand.

So here's the thing. Obviously I have a personal beef with the existence of vehicles like this, but my eyes cannot deny the facts - the X4 looks fantastic. It's muscular, imposing and smooth all at once. Unlike the X6, a bigger and less visually successful attempt to play the same styling tricks with an X5, it doesn't have a ridiculous rear view that looks like it shoulders and buttocks have been fused (although it's hard to miss just how small the rear window is).

Even more impressively, there's no denying it looks better than the X3 that gave birth to it, so I can easily see why someone in a BMW showroom could be drawn to it. At least until they sit inside.

If the exterior style and eye-catching Sophisto Grey metallic paint don’t make an immediate impression then your eyes will surely widen at the interior, resplendent with bold Tacora Red seats, Aluminium Rhombicle trim finisher and the kind of sleek, classy styling that BMW excels in. 

Both the adjustable ambient lighting on the doors (we were partial to lilac) and door projectors that shot out what looked like robot wings onto the ground every time we hopped out of the X4 at night walked a fine line between futuristic cool and “parked out the front of a nightclub entrance” chintz, but over time the scales tipped more to the former. 

The big differentiator between the X4 and X3, of course, is the sloped coupé roof, a design feature that may make the X4 look a little cooler, but at the expense of cabin space, but more of that in a moment.

Where the previous X2 was a very small crossover with niche appeal, the increase in size for the new model means more people will be interested in it. Possibly even people with a small family.

Those increased dimensions pay dividends inside, with ample headroom up front and more than enough space across the front row, although the raised armrest console is somewhat narrow. 

The seats in both the iX2 xDrive30 and the M35i xDrive are very supportive thanks to ample bolstering, but both were also on the firm side. The iX2’s synthetic leather was slightly more comfortable than the M35i’s sports-focused front seats.

The power-adjustable seats and height- and reach-adjustable steering wheel means it’s not hard to find a decent driving position, but forward vision is impeded by a very thick A-pillar, and the letterbox-like rear windscreen in the X2 means rearward vision is limited. Good thing it has excellent parking cameras and sensors. 

Storage is decent in the X2, with room for big bottles in the door cavity, and a few nooks and large open spaces in the console. Although secure storage is limited with the armrest housing a very shallow space. I do like BMW’s phone charger setup. Rather than lying on a pad, it slots into a vertical holder that has a latch to keep it in place when cornering. The only drawback is that you can see the screen which could potentially distract some drivers.

The X2 introduces operating system nine to iDrive, which is housed in the central part of the curved display and operated by touchscreen or the controller on the floating central console. After some familiarisation, the functionality isn’t that much different to the previous version of the operating system. The main menu looks cool and is mostly easy to navigate. The sub-menu icons - of which there are heaps - look a little Microsoft Windows.

The X2 has drive modes that also interact with the interior of the car and change lighting, EV noise and more. They include Personal Mode, Sport Mode and Efficient Mode as standard, but if you opt for (and pay extra for) BMW Digital Premium, the modes extend to Expressive Mode, Relax Mode and Digital Art Mode. Some of these are quite cool, especially some of the EV sounds, but would I use them everyday? Probably not.

The clearest indication of increased space is in the second row. There’s much more legroom than the old X2, and behind my six-foot frame I had enough space with a couple of centimetres between my knees and the front seat backs. Toe room was very limited, however. 

The roof has been scalloped out to ensure more headroom, which is welcome given the extra sloping roofline.

There are a pair of USB-C ports back there, lower air vents, map pockets, decent door storage, and a centre armrest with cup holders.

The boot is sizeable, in both engine grades but you only get a tyre repair kit. There is underfloor storage for the charging cables in the iX2.

At 560 litres with all seats in place and 1470L with the second row stowed, the petrol grades have a bit more space than the iX2 at 525L (all seats in place) and 1400L (second row lowered).

For a car that is very much a mid-sized SUV on the outside, the interior can feel a bit too snug, like you’re driving a compact car that’s tried on a suit a few sizes too big (for reference, I’m 175cm tall - above-average height drivers may find the snugness soon turns to claustrophobia). 

While comfortable - it is BMW we’re talking about, after all - there’s not an overly abundant amount of headroom available, a feeling that becomes more pronounced should you shut the big moon roof.

My two children felt slightly too close to “you’re annoying me” distance from one another, which is to say this isn’t really the kind of car you should be getting if you plan on regularly ferrying about passengers in the rear who are bigger than a child. But I really don't think many people with kids would choose the X4 over the X3.

Boot space also takes a hit when compared to the X3 (550 litres versus 525-litres in the X4 - I was surprised the difference wasn't larger - although that expands to 1430-litres with the rear seats folded down. 

The boot opening is also mouth-shaped, which makes packing in wide-load items more of an issue.

Cupholders are plentiful - two in the front, two in the rear, and bottle holders in each door - and there’s a decent-sized storage cubby in between the front two seats. 

The sloped roof, and big fat A pillars, also result in the X4 being a bit more pinched at the rear, which is not especially great for visibility, with the vehicle’s blind spots taking some getting used to.

Cost-wise, the X4 is roughly in the same ballpark as the other cars in this strange sub-segment, but when you add in optional extras - metallic paint, panorama glass sunroof and BMW Laserlight headlights among them - the base price of $95,900 plus on-road costs sneaks up to $101,800, which is is no small figure. 

It’s also a considerable $8000 more than the SUV-shaped X3, meaning you’re essentially getting the same car, but with less cabin and boot space, for more money. To be fair, this is just part of a long tradition of the style-conscious buyer being willing to pay more for less, one that the invention of the coupe pretty much invented.

That kind of money also makes exclusions like adaptive cruise control, heated seats and wireless charging a bit of a head-scratcher.

Still, there’s plenty to love, including an M Sport kit that comes standard with the X4 (a suspension/brake package and various styling embellishments), butter-soft Tacora Red Vernasca leather seats (Sport adjustable for the driver and front passenger), 20-inch M light alloy double-spoked wheels, a head-up display, adaptive LED headlights, and an automatic tailgate. 

There’s also a generous high-resolution 12.3-inch control display and digital 12.3-inch instrument display, the former operated by touch or via the rotary iDrive Touch Controller. 

Cable-free Apple CarPlay and Android Auto are also available, but BMW allows you the option to use its iDrive system instead, just in case you're some kind of mad Munich fanboy - or you hate Apple. 

Each of the four grades come with a different powertrain, and the xDrive20i kicks it all off with its 2.0-litre four-cylinder turbocharged petrol unit, making 150kW of power and 300Nm of torque. It drives all four wheels via a seven-speed dual-clutch transmission and can hit 100km/h in 7.4 seconds.

The xDrive M35i ups the fun factor with a gruntier 2.0-litre four-cylinder turbo-petrol unit, driving all four wheels via the same transmission as the 20i, all while delivering power and torque of 233kW/400Nm This ensures a 0-100km/h dash of 5.4 seconds.

The iX2 eDrive20 is powered by a 150kW/247Nm electric motor on its front axle, and the iX2 xDrive 30 uses two motors - one on the front and one on the rear axle for all-wheel-drive traction. The total system output is 230kW and 494Nm and the xDrive30 gets to 100km/h in just 5.6 seconds.

Now, prepare to be confused. In the past, the 3.0 in the xDrive3.0i nomenclature might have led you to believe you'd bought a BMW with a 3.0-litre straight six engine. But in this case, you have not, the 3.0 just means you have a more exciting version of the 2.0; a TwinPower turbo 2.0-litre inline four-cylinder engine, making 179kW and 353Nm that the xDrive system delivers to all four wheels. 

The claimed zero to 100km/h time of 4.9 seconds feels completely realistic as this engine has plenty of poke. Put it in the Sport setting and you'll get some serious shove. Indeed, the switch between Comfort and Sport is very noticeable and changes the character of the car entirely.

The transmission is an eight-speed conventional torque converter automatic gearbox that’s both smooth and responsive. 

A fuel-use figure for the xDrive20i is yet to be confirmed, but the front-wheel-drive sDrive20i offered in Europe with a three-cylinder engine sips as little as six litres per 100 kilometres on the combined cycle. Expect the Australian version to be a little higher than that given it’s AWD and has a more potent engine.

The M35i consumes 7.7L/100km. 

The high-voltage 64.8kWh lithium-ion battery in the iX2 ensures a driving range on the WLTP cycle of between up to 477 kilometres in the eDrive20 and between 417 and 449km for the xDrive30. 

The latter has an energy efficiency range of 16.3 to 17.7kWh/100km, and BMW says you should be able to top up the battery from 10 to 80 per cent in 29 minutes at a fast charging station.

That driving range is not bad compared with the Lexus UX300e and Peugeot e-2008, but not quite as impressive as the Volvo C40 twin-motor. 

I missed out on checking the energy efficiency figure of the iX2 xDrive30 following our drive, but after an 88km drive loop, the iX2’s range had dropped by 91km, which is just a 3km difference.

The X4’s 65-litre tank needs to be 95-octane at a minimum, and BMW’s claimed combined fuel consumption is 7.9 litres per 100km. The temptation to use its rorty little engine is going to push you higher, though - you chose the one with the 3.0 badge on it after all - and we averaged 10.9 litres per 100km in our week together, which was mainly city driving, to be fair. 

The M135i xDriveis undeniably quick off the mark. The lovely 2.0L turbo engine is well matched to the seven-speed dual-clutch and it’s responsive and willing from a standing start and when overtaking.

The engine sounds lovely too, although we suspect it’s amplified in the cabin, and steering is as sharp as it should be in a warmed-up performance SUV. We darted through some very twisty roads outside Lisbon and had quite a lot of fun in the process, so the M Performance badge is justified. 

I drove the previous-generation X2 M35i a few years back and was disappointed with the ride quality. It was quite jiggly on uneven road surfaces and way too firm.

While the new version still has a firm tune to aid dynamic driving, it is much more compliant than the old car and overall ride comfort has improved.

The iX2 is also quick off the mark and in xDrive30 guise is only 0.2sec slower to 100km/h than the M35i. 

That lively, smooth EV acceleration is present here, adding a sense of fun to the iX2.

It too has sharp steering, and the cabin is hushed. Not just because it’s an EV either. We were on coastal roads on a windy day and there was only a hint of wind noise in the cabin.

In some instances taking corners that had typical European walls or houses right up against the road, the iX2 would slow before I had a chance to tap the brakes. But it was hard to tell if that was a vehicle safety function, or the regenerative braking.

The ride in the iX2 was a bit of a mixed bag. It coped with some of the pockmarked roads exceptionally well, soaking up the imperfections. But then on other roads it was a little choppy.

It also bounces a little when you go over speed bumps, but that’s not exclusively an iX2 trait. I’ve felt it on many an EV, given the placement of the very heavy battery packs under the floor.

On the driving tech front, the X2 has a well executed head-up display projected directly onto the windscreen. It includes the speedo of course, nav guidance, a crystal clear display and more info. 

The impressive trick that BMW continually pulls off with its SUVs is giving them the same sensual, muscular steering as its sedans, and an impressively similar ride and handling balance.

The steering is the highlight here, but it's also noticeable how planted to the road it feels.

The X4 speaks to its looks, in fact, by feeling sportier and more alive to drive than you'd expect an X3 to be.  

This is less an SUV for soccer mums and dads, and more a bastard love-child that’s into loud leather and bright neon - a CEO who dressed punk rock-lite on weekends, if you will. 

If those weekends are bereft of child taxiing and loading up the boot with several tons of kid stuff, then you’ll have a blast in the X4. 

A 2018 test gave the X4 a five-star ANCAP safety rating, and an easily located button on the dash brings up the vehicle’s safety suite if you’re the kind of driver who likes to make a few adjustments. 

A 360-degree camera offers multiple viewpoints and is a godsend when parking the X4, since the cabin makes the car feel smaller than it actually is on the outside, and the range of safety features on offer are more than adequate. 

Those include autonomous emergency braking, dynamic braking lights, dynamic stability and traction control, rear-cross traffic alert, speed limit information and hill descent control. 

The X2 range is covered by BMW’s five-year, unlimited kilometre warranty - something the German giant only increased from three years back in 2022. This is now the minimum standard.

The battery warranty for the iX2 is eight years or 160,000 kilometres. 

BMW does not have scheduled servicing terms, instead, servicing is condition-based and the car’s computer will alert the driver when to book in for a service.

A five-year servicing package will cost you $3171 for the petrol X2s, while the iX2 is $2186 for six years.

Despite all the brouhaha about other car manufacturers offering more generous warranty periods - seven years for Kia, for example - BMW has not shifted its stance, still offering its standard three-year unlimited-kilometre warranty. Frankly, it's just not good enough.

BMW also offer a Service Inclusive package for $2010 that covers owners for five years, or 80,000km.
