Subaru Outback vs BMW X4

What's the difference?

Over 30 years and seven generations of Outback in Australia, the latest might just be the best.

It's great to drive, even better to sit in, very easy to live and willing to go further than most equivalent large SUVs at its price point.

The styling is definitely divisive, with purists unhappy that the long, crossover wagon silhouette is now gone, but what we have instead is a family-friendly vehicle that pleases on so many fronts.

We’d go as far as saying the latest Outback might be the most-rounded Subaru currently available, and great value to boot. And the base AWD is all the SUV most people will ever need.

That’s not bad for something this square!

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.

Historically, Subarus have majored on quirky. Kooky even.

Think buggy ‘60s 360, offbeat ‘70s 1400, spacey ‘80s Vortex, futuristic ‘90s SVX, Alfa-esque ‘00s pre-facelift Tribeca, dorky ‘10s Exiga. We’d go as far as saying that, in over 50 years, only a handful of Subarus have looked normal. And they’ve all been boring. The beautiful ones, like the original Impreza and ’03 Liberty, remain stunning.

But quirkifying such an important family car in such a mainstream segment… that's risky. And we’re here for Subaru’s boldness. We just wish the details weren’t so heavy handed.

Longer, larger and wider than any prior version, the 2026 Outback shares its stretched platform architecture fundamentals with the latest Forester. That’s a sound basis. Just Xeroxed up by about 15 per cent. Boxy shape. Deep glass. Wide doors. Form over function. This is designed to make life easier.

What you make of the Wilderness’ visual features, including the dramatic grille mask, SUBARU wording, painted trim surrounds and cladding-on-cladding (behold the Kia Tasman-like squared-off wheel arches if you dare) is down to personal taste. Eyes be damned! But it is so far-removed from the elegant grace of the previous model that some might argue a name change would at least have silenced the critics.

On the other hand, besides fugly being in Subaru’s DNA, a large, lofty SUV is probably truer to the term ‘outback’ than on any elegant and gracefully-silhouetted crossover wagon.

Meanwhile, the polar opposite is true inside. It’s as if the interior designers strove for class and calm, with none of the exterior styling’s visual noise, or shouting in the Wilderness’ case. And there is the luxury of space, vision and scope, further enhancing the Outback’s usefulness. That you can’t see the body, just the beautiful cabin’s detailing, elevates this Subaru. Unlike in the previous model, which was a bit of an aesthetic and functional mess inside.

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.

Like all Subarus, Outback boasts an interior of very high-quality craftsmanship, being built beautifully, without rattles or noises or jarring trim.

The difference here is just how pleasingly practical and easy yet attractive this environment is, from the moment that wide-opening door opens and shuts with reassuring solidity.

The horizontal dash layout departs from the Tesla-aping portrait screen domination of the previous generation, banishing the confusing and annoying virtual controls for real, live buttons.

But is it original? The layered presentation is attractive and distinctively Toyota… err Subaru. Yes, it is very much like the bZ4X-based Solterra EV’s look inside.

That’s no bad thing from an ergonomic point of view. The driving position is flawless, the seat/wheel/controls relationship considered and the placement of the climate controls, audio system, armrest and storage just right. We’re also happy to see the instrumentation display incorporate various visual choices, including digital analogue-style dials.

A particular callout goes to the slick and speedy tactility of the brand’s latest touchscreen, as well as the (again suspiciously Toyota-like) interface and graphics layout. It’s all good.

But wait, there’s more. The Outback’s front seats are claimed to be particularly supportive, and after hours in them on and off road, they seem to exceed Subaru’s claims.

If you’re expecting regular mid-sized SUV levels of interior space, be prepared to be impressed, because the Outback’s extra sizing outside seems to be multiplied inside. There’s ample room for long legs, big hats, broad shoulders and buxom hips. It all works so well. This is probably one of the best modern SUV interiors, period. Nothing seems to have been overlooked.

The rear seat is presented to please, too. It can seem a bit drab in the lower-line models, but the same virtues of effortless entry/egress, seat comfort, convenience (including air vents, USB ports, cupholders and armrest placement) apply. We noted the lack of road/tyre noise intrusion at speed, too.

Behind the very sixties Jeep Wagoneer-looking rear is a vast luggage area, complete with a low floor, remote rear-seat folding handles, 12V outlet and quality trim. And that space-saver spare lives underneath.

Subaru seems to have designed this car from the inside out and it shows. A rare 10/10 from us.

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. 

Don’t worry, Subaru traditionalists. The Outback again offers a pair of horizontally-opposed 'boxer' four-cylinder engines.

The regular Outback versions are powered by a 2.5-litre twin-cam petrol unit making 137kW of power at 5800rpm and 254Nm of torque at 3700rpm.

Choosing the Wilderness switches things up to a 2.4-litre turbo version delivering 194kW at 5600rpm and 382Nm between 2000rpm and 3600rpm.

Both use a continuously variable transmission (CVT) with eight artificial ‘steps’ for a more torque-converter-like experience. Sadly, no manual gearbox is available.

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. 

Where the Outback regresses compared to its predecessor is efficiency.

Despite a modest 50kg weight rise, the substantially boxier shape is probably behind the jump in petrol consumption, rising nearly one litre per 100km compared to before in the Outback, and nearly 2.5L/100km, in the heavier Wilderness.

The combined average consumption figure for the 2.5-litre naturally aspirated engine is 8.1L/100km, for a carbon dioxide emissions rating of 183 grams per kilometre, while the 2.4-litre turbo manages 9.7L/100km and 228g/km.

Filling the 63L tank, expect an average range of about 777km in the former and just 648km in the latter. Surely, the coming hybrid version can’t arrive soon enough for some buyers.

At least both engines can drink from the standard 91 RON petrol bowser.

So much for the theory. Out in the real world, over a solid day's testing on- and off-road, we found there was a difference of about 1.5L/100km between the regular Outback and the Wilderness.

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. 

Confession time. The way the previous Outback drove was profoundly disappointing. The steering felt numb, the ride was too stiff and the car seemed wilfully dull, even in the turbo version.

The contemporary Forester ran rings around it for driving pleasure and refinement.

But Outback number seven is completely different and maybe the best-driving non-WRX Subaru right now.

From the moment you climb on board this vast SUV from Japan, everything feels right – from the driving position and relationship with the controls, to the sumptuously comfy seats and commanding vision all around the vehicle. That’s a promising start.

Push the ignition and press the accelerator down, and the regular Outback 2.5 quietly, gently and smoothly moves off the line. With modest power outputs and a CVT, you might expect it to also sound revvy and droney, but instead the acceleration is strong and throttle responses determined.

We drove this for hundreds of kilometres and never found the performance lacking, even with three adults and their luggage on board, over hilly and even mountainous terrain. Yes, it is possible to have the CVT whining at higher revs, but not within normal driving scenarios. And the quietness and lack of road noise is terrific.

Moving to the Wilderness and its 2.4-litre turbo powertrain, the same applies, except of course mid-range response is significantly faster and with a slicker, more refined delivery. Press and squirt, this is deceptively quick, because the car does a great job in masking the noises and vibrations that working an SUV hard often elicit.

We only wish there was a manual option. With steel wheels, cloth seats and without the Wilderness' add-on gargoyles.

Now, it also seems that Subaru listened and learned from previous criticisms like ours, because the Outback’s newly-redesigned steering is a delight, with a natural, fluent sweetness and ease that’s combined with a pleasing connection with the driver.

The result is balanced, controlled and enjoyable handling, backed up by reassuringly stable road holding. We drove through a sudden, heavy thunderstorm near Bathurst on the first, hot summer afternoon’s test session, and found the Outback to feel impervious through such slippery conditions.

And this all largely applies to the Wilderness as well, though its 20mm-higher ground clearance (to 240mm) makes it feel a little less composed than the glued-down regular model. Both feature a stiffened body and multi-link rear suspension, by the way.

More progress has been made in the Subaru’s ride quality. Gone is the hard suspension feel, for a far-less firm set-up, providing a comfortable and queasy-free ride. Even in the loftier Wilderness. This is the model’s greatest advance over its predecessor and we’re extremely happy with the outcome.

Finally, other than the at-times over-eager driver-attention monitor, the ADAS tech provides subtle, nuanced back-up, with quiet lane-keep intervention, a measured adaptive cruise-control functionality and no jarring buzzes and warnings.

We also enjoyed a session taking both grades off road, to show off their 4WD prowess. The clearances are ample, the hill-descent tech effective and the ability to scramble over wet rocks impressive. The Wilderness especially may even live up to its name!

This is a difficult SUV to fault. The Outback’s breadth of capability on and off the beaten track give it an unusually wide bandwidth for what is a monocoque bodied family convenience. That there is so much sophistication and fun to be had as well make this so much better to drive and live with than the disappointing old version.

We can’t wait to get to know the latest Subaru better on more familiar roads.

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. 

Subaru offers a five-year/unlimited kilometre warranty, and that also comes with 12 months of roadside assistance.

Now, that's pretty average nowadays, so nothing special, particularly when other SUV companies like Mitsubishi, Nissan and MG offer conditional 10-year warranties.

Service intervals are at 12 months or 15,000km for both engines. There is a capped-price servicing offer covering this timeframe. They are currently listed at approximately $350, $530, $405, $705 and $370 for an average of $472 per workshop visit.

There are 128 dealers or authorised Subaru service centres across Australia as of January 1, 2026.

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.
