BMW X3 vs Subaru Forester

What's the difference?

If a BMW X3 is for you, then we have no quarrels with that. It’s a better all-round vehicle than the one it replaces and represents better value. And even though BMW mandates a hybrid driveline, there are still some significant choices within that framework.

By all means buy the M50 if you crave the rush of acceleration that almost 300kW can provide. And if efficiency is your altar of choice, then the plug-in 30e makes a lot of sense, too.

But even if you can afford either of those two more expensive variants, whatever you do, don’t dismiss the entry-level 20 model. At least drive it alongside the others and then make a decision based on all the facts, and not the assumption that entry-level equals the car you afford rather than the car you want.

It might be cheaper, but there’s absolutely no doubt that the 20 model is the one that shines and arguably makes the most of the opportunities BMW’s latest tech offers.

Sometimes less really is more.

Don’t let the 7.5/10 make you think the Forester is not a good car. For the person who needs a practical, off-road-capable mid-size family SUV without too many complications, it’s extremely hard to look past this thing.

Is the STI Sport the best choice in the range? Not for most, given its higher price and relative lack of extra ability to go with it. A standard suspension tune and even a slightly less plush interior are probably a better call for most family needs, which means saving a fair bit at the purchase.

It’s also worth noting that the next generation Forester is coming soon, and with that could come a price hike. If a Forester is on the shopping list but the cost of living is starting to bite, now might be the time.

If the slightly sharper handling and red interior leather is of interest to you, the STI Sport might be worth a look, but just know the Forester’s best attributes can be had for less money in a much cheaper variant.

It might be badged an X3, but this is no small vehicle. In fact, it’s bigger than the original BMW X5 (which set the tone for this entire market segment) with a length of 4755mm (4667mm for the first X5) and a width of 1920mm (1872mm). That said, it’s 25mm lower than the outgoing X3 in a move to emphasise its sportiness. Shorter it may be, but it’s also 16mm wider on the front track and 45mm wider on the rear than the outgoing model.

BMWs latest styling cues also appear in the new car, including the large, split-kidney grille that, for Australian-delivered cars, is also lit around its edges. The short overhangs that characterised the original X5 (and soon characterised this whole BMW genre) remain, and the T-graphic LED tail-lights round out the stylistic touches.

The other thing we noticed (and we’ve seen it on other cars recently) is a panoramic sunroof that doesn’t actually open.

The Forester is a pretty good-looking thing in this writer’s eyes, but its design hasn’t changed dramatically in the last few years.

The mid-size SUV looks equally at home on inner-city residential streets and in the middle of nowhere, even with the slightly ‘sported-up’ black trim of the STI version. And I do mean ‘slightly’.

Aside from the fact it looks a lot like the Forester 2.5i Sport of a few years ago (without the red bits), the STI Sport is perhaps ironically unadventurous. Even its alloy wheels don’t scream ‘sports’.

For all the SUVs with their respective brands’ performance badging (and not engineering) attached to them that bear more bark than bite, maybe it’s not such a bad thing Subaru has refrained from putting the Forester in full Tecnica uniform.

Inside, however, the black and red leather seems determined to distract from the fact that not much else has changed cabin-wise. It feels visually busier than it needs to, but still falls on the correct side of the restrained/garish line.

But there’s probably a reason the interior feels a little bit ‘classic Subie’ - if it works, it might pay to avoid making big changes.

Cabin space is plentiful in the X3 with loads of room in the front, possibly thanks to the dashboard that is pulled back from you with only the twin screens and steering column offering themselves up to the driver. Even the air-vents are somewhat hidden. There’s good vision out and the seats themselves are lovely. The step into the cabin feels to be at just the right height, too; not too high, not too low.

Rear seating is good, too, although the X3 will always be better as a four seater than five thanks to the shape of the rear bench, but the glass roof opens the space up and there’s plenty of charging points and storage nooks. The sun blinds on the rear-side windows of the more expensive versions should be standard kit on every car sold in Australia.

We’ll take exception to the new gear-selector which doesn’t have a defined Park position and instead relies on applying the park-brake to engage Park. But the ambient light and contrasting cabin colours are a bit of a breath of fresh air.

There are levers in the cargo area to quickly fold the rear seats (60:40) at which point luggage space jumps from 570 litres in the mild hybrid cars to 1700 litres. The battery-pack of the 30e model means that luggage space starts at 460 litres and can be expanded to 1600 litres.

The latest version of BMW’s sometimes controversial iDrive operating system is simpler and easier to use than before and supported by a new operating system, but there’s still some familiarisation necessary. One improvement has been the addition of QuickSelect which works somewhat like the old favourites button system and gets around the need to drill into menus to access the functions you want.

A head-up display is a terrific addition, although where some displays are more tolerant of polarised sunglasses, the HUD in the BMW didn’t like mine and went dark at the most inconvenient angles.

None of the X3 variants feature a spare tyre of any sort. The 19-inch tyres on the base grade are run-flats, while everything else gets a repair kit for roadside emergencies.

If you want to tow, the good news is that all X3 variants can do so. But you will need to purchase the $2200 towing package which enables the X3 to haul a trailer weighing up to 2000kg with a maximum tow-ball down-weight of 200kg.

I've heard the Forester called a ‘jack of all trades, master of none’ kind of car, and I reckon that’s unfair. Aside from having Subaru’s venerable all-wheel drive at its disposal, the Forester is a supremely practical SUV - exactly what it needs to be given the reasons most people buy SUVs.

Okay, so the interface and tech is pretty old. If you’ve been in a Forester built in the last few years, there’s not a lot new to find.

There are some deliberately large buttons, the climate controls are still very classic and tactile, even the steering wheel buttons are pretty chunky.

If you’re not used to the amount of technology in new cars, Subaru has tried to make this as easy as possible to navigate.

I hate to sound like one of those ‘back in my day’ people, but in a lot of cases I’m finding myself preferring interior layouts and controls of a few years ago rather than post-2020 screens and ‘iPad’ style controls.

Newer Subarus have a rather large portrait centre screen, and even though it works fine, this one with the buttons below it is easier.

The instrument cluster being a pair of physical dials is also welcome, even if it means the digital display looks many years older than the car really is.

It’s also a spacious cabin, if not just physically then in feeling also. The huge sunroof and high-visibility glasshouse means plenty of light comes in and makes it feel roomy while also of course being easy to see out of (and therefore, manoeuvre).

Ergonomically, the Subie is sound. The seating position, aforementioned driver visibility, controls placement and space around each passenger is practical and well thought out, plus moving back into the second row doesn’t feel like a huge comfort downgrade.

Light in the second row is also good, the seats recline and the touch-point materials are like the front seats - comfy leather and a lack of scratchy plastics unless you go looking for them.

The second row can also be folded down (in a 60/40 split) from the boot with controls near the electric tailgate, which brings the boot space from 498 litres to 1060L, though Subaru says maximum space available is 1740L up to the ceiling.

At $48,640, before on-road costs, the Forester STI Sport AWD (to use its full name) has some strong competition - there are high-spec AWD hybrid Toyota RAV4 GXLs, powerful front-drive SUVs like the Ford Escape Vignale and Hyundai Tucson N-Line hybrid, or even variants of Euros like the VW Tiguan and Renault Koleos all within $1000 of the STI Sport’s sticker price.

But those looking for the practicality the mix of Subaru’s AWD, the space inside, and perhaps even the slightly older interior can provide, there’s a decent list of features for a car coming in at just a slice under ‘fifty large’.

The STI Sport AWD is based on the top-spec (petrol) Forester 2.5i-S, so it shares plenty of standard features - read on for those - but the key additions for this variant include a suspension tune by the eponymous performance division, a combination black and ‘Bordeaux Red’ interior leather with red contrast stitching, STI badging inside and out, dark grey 18-inch alloy wheels and black exterior trim for the grille, mirrors, roof rails and light surrounds.

From the Forester 2.5i-S, the STI Sport also brings along the existing leather seats and trim, with power-adjustable fronts which are also heated, plus the other main interior features like the 8.0-inch touchscreen for multimedia with wired Android Auto and Apple CarPlay, an eight-speaker Harman Kardon sound system with subwoofer and amp and a large electric sunroof.

It’s lacking some more modern features like wireless phone mirroring, wireless phone charging, USB-C ports or a fully digital driver display, but the latter of those is certainly no great loss.

On the outside, the existing self-levelling LED headlights with cornering response, LED DRLs and fog lights, privacy glass, roof rails and electric tailgate all also carry over from the 2.5i-S.

There are certainly rivals with more features, but they require trade-offs in other areas that might not appeal to Subaru customers.

Hybrid tech across the board is the key phrase here, with the base-model 20 xDrive fitted with a mild hybrid electric motor and battery pack that works in conjunction with the 2.0-litre, turbocharged petrol four-cylinder engine. Power is 140kW and torque 310Nm. Like most mild hybrids, the electric motor offers power regeneration during braking, a mellow (by EV standards) kick in the pants during take-off and acceleration and also acts as the car’s starter motor.

The performance flagship, the M50 xDrive taps into the same technical philosophy with a mild hybrid augmenting the turbocharged six-cylinder inline petrol engine. In this case, however, peak power is a hefty 293kW and torque maxes out at 580Nm.

The most technically adventurous X3 is the 30e xDrive which uses plug-in hybrid tech to offer a claimed 91km of electric driving, about twice that offered by the original X3 PHEV it replaces. When the same 2.0-litre four-cylinder petrol as fitted to the 20 xDrive, and the electric motor are humming along together, there’s 220kW of power and 450Nm for the taking. The PHEV X3 can run in purely electric mode at up to a claimed 140km/h.

All variants use BMW’s familiar eight-speed automatic transmission and in each case, drive is sent to all four wheels on a permanent basis. Interestingly, the 30e and M50 versions package their electric motor as part of the engine-transmission combination. The 20, meanwhile, places its electric motor externally, as part of the drive-belt rotating assembly.

The M50 model has an M button that unleashes the full performance with one touch, and features an electronically locking rear differential in the interests of high-speed turn-in.

Adaptive suspension that varies the degree of damping is also part of the package on each X3 variant.

The same drivetrain as is used in the 2.5i-S is found in the STI Sport AWD.

No prizes for anyone who guessed it’s a 2.5-litre flat-four engine, but some might be disappointed to know that means no turbocharging and no sporty transmission - the STI Sport still outputs 136kW and 239Nm via a continuously variable transmission (CVT).

Subaru’s ever-present ‘symmetrical’ all-wheel drive system is, of course, here in the Forester too, but the brand’s relatively recent foray into hybrid drivetrains was given a miss for this version.

As you might expect, the PHEV 30e model is the efficiency superstar of the X3 line-up with an official combined test figure of just 1.6 litres per 100km and 38 grams of CO2 per kilometre. The four-cylinder 20 xDrive is not bad for its size at 7.5L/100km (and 171g), yet the bruising six-cylinder M50 version with all that performance is not too far behind with an official figure of 8.2L/100km (187g).

The 30e PHEV features a selectable battery-saving mode as well as the option of forcing EV-only running. It features a 19.7kWh battery and BMW claims it can charge using a three-phase, 11kW socket from empty to full in two hours, 15 minutes. It does not make use of fast-chargers.

Exactly how far you’ll travel in the PHEV model will depend hugely on how and where you drive. On long, open road journeys, fuel consumption won’t be much different to the others, but with just a 50-litre fuel tank, it’s range won’t be stellar. But in urban running where the batteries are being recharged for free as you brake, the difference will be significant. Meanwhile, with a 65-litre fuel tank in the mild hybrid grades, the theoretical range (based on the official fuel number) is 865km and 765km for the 20 and M50 respectively.

While BMW recommends premium fuel for maximum efficiency, it also says that each X3 variant will not be harmed by the use of standard ULP if that’s all you can get hold of.

Subaru claims a 7.4L/100km combined cycle (urban/extra-urban) fuel consumption figure for the STI Sport AWD, and while we’ve seen tests come close to that in other variants of the Forester with the same drivetrain, inner-city life can be a detriment to the Forester’s drinking habits.

On a test loop which was fairly unsympathetic to fuel efficiency, the Forester’s trip computer reported a 10.2L/100km figure, though a commute from inner-Melbourne to the CBD saw the digits nudge 13.0.

Historically, highway driving has been better for the Forester, and the STI Sport should be no different - plus its 63-litre fuel tank (able to run on 91 RON) should mean if you can approach Subaru’s claimed fuel consumption figure, you could theoretically find yourself driving more than 800km on a single tank.

Big heavy SUVS like this one haven’t always been too dainty on their feet. The extra bulk and height mean suspension has to be firmer, the big wheels and subsequent loss of tyre sidewall depth plays against ride quality and before you know it, the compromises have piled up and the driving experience has gone to hell.

This time, however, BMW’s claim that the X3 was designed from the start as an SUV and not converted from a sedan platform seems to hold water. There’s an overall greater sense of cohesion in the way the car steers and flows through corners and faster bends. The steering feel and feedback are a big part of that, too, and the whole seems at least as great as its parts.

The M50 is, predictably, a rocket with loads of accessible acceleration and a great noise while you’re enjoying it. That said, the 21-inch wheels and tyres don’t do anything for ride quality, but it remains an entertaining performance car in a familiar, ICE kind of way.

The plug-in is also perky with its 220kW on tap, but it’s less old-school and more techy. And while you can’t pick the point at which ICE hands over to electric and vice-versa, sensitive drivers will absolutely know that there’s a big dollop of electrical assistance when your right foot starts asking the tough questions. It definitely feels more overtly hybrid, though that shouldn’t be any kind of surprise, purely because that’s precisely the case.

Which brings us to the 20 entry-level grade. And while it’s going to be a controversial statement, this emerges as the most cohesive, rounded variant of the new X3. There’s something in the way the fizzy, bubbly (but very smooth) 2.0-litre four-cylinder provides more than enough urge, but never threatens to dominate the dynamics.

With less weight over the front wheels than the M50, and less weight overall than the PHEV, the 20 corners flatter, steers more intuitively and is simply more fun more of the time. Even on the optional 20-inch tyres, it rides better than the others, too, and might even be better again with the standard 19s other than the fact that those are run flats and we didn’t get try them.

Like much of the Forester STI, the driving experience is heavily borrowed from some tried and true Subaru characteristics.

That naturally aspirated flat-four engine, though underwhelming on paper, gets the job done without much fuss. In fact, it sometimes feels peppier than it should given its outputs.

Its 'S/I' (Sport or Intelligent) drive mode selector is there to adjust acceleration style, but it doesn’t make an enormous difference.

Yes, it could do with more torque, but the engine doesn’t struggle and only starts to sound laboured at high revs during the kind of acceleration you’d need for seconds at a time.

The sound of a CVT whirring away isn’t exactly auditory bliss, nor does it make for engaging acceleration.

But it’s relatively quiet under regular load below highway speed and, as long as the road isn’t too coarse, NVH is generally good in the Forester.

Road, wind and engine noise are certainly present in certain circumstances, but they’re not intrusive until you get to higher speeds.

At those high speeds is where you might notice one of the most significant changes to the STI version of the Forester - the dampers have been retuned by STI, for what Subaru hopes is a “sharper, more responsive driving experience”.

It’s hard to seriously call the Forester sharp - it’s a mid-size family SUV with enough clearance to go light off-roading - but the STI Sport holds up well for what it is.

The Forester driving experience was already likeable and easy, and in terms of cornering and handling bumpy rural (or even just bumpy urban) roads, the suspension keeps things under control without feeling too stiff.

Its body doesn’t roll as much as you might expect when cornering, but given STI’s engineers focused their efforts on the dampers, its a good thing the Forester doesn’t either waft or thud when presented with big sharp bumps, nor does it vibrate and rattle over constant rough surfaces.

Of course, it’s also got 'X Mode' controls for different surfaces like snow, dirt and mud, making it a pretty handy companion for outdoor adventuring or camping trips in regions where the weather gets a bit unpredictable. If you’ve ever tried to get a front-wheel drive hatchback out of a muddy hillside campsite…

Essentially, the Forester is the kind of SUV that, if you wanted to, you could have a medium amount of fun with on a twisty road before taking it down a particularly rough, unsealed or muddy trail, then later hand the keys to your grandma knowing she’d be able to handle everything about the driving experience, too.

The Forester holds a maximum five-star ANCAP rating from assessment in 2019, which sounds outdated but arguably the most important aspects of the ANCAP testing are the crash protection, for which the Forester scored highly - an extremely good 94 per cent for adult occupant protection and 86 per cent for child occupant protection.

Seven airbags including dual frontal, side chest, curtain airbags and a driver knee airbag keep occupants protected, while Subaru notes the engine’s low-centred nature means it’s designed to slip under rather than into the cabin cell in case of a frontal collision.

Its active safety systems have been kept up to date, with functions like lane-keep assist, driver monitoring, automatic reverse braking and the help of Subaru’s ‘EyeSight’ monitoring system are all welcome additions, particularly since they’re not as intrusive as some rivals.

The lane-keep assist, for example, only beeps (relatively calmly) and intervenes when the Forester actually approaches the lane edge, and the driver monitoring and speed warning systems don’t chime or give warnings unless something is actually going wrong.

Like the multimedia and interior layout, the active safety is one area where the most recent previous generation of common features seems to be better than those many manufacturers are now implementing.

BMW’s warranty on the X3 is the company’s usual five-year/unlimited kilometre deal. But in this case, there’s also a six-year/100,000km warranty on the high-voltage battery.

Also typical for BMW is the service interval which is not a set time or distance and instead is determined by how the car has been used. It’s called condition-based servicing and it’s nothing new at BMW.

There’s also capped-price servicing available. For the X3, the five-year/80,000km service package is $2475.

Subaru’s five-year/unlimited kilometre warranty is now considered the minimum par-for-course coverage for a mainstream new car in Australia, while some rivals are offering seven-, eight- or even 10-year warranties (though the longer one are sometimes conditional).

Subaru also offers 12 months of roadside assistance, though this is also often offered in similar lengths to warranties by competitors.

Servicing intervals for the Forester are every 12,500km or 12 months, with the first of five capped price services (aside from a free one-month check-up) costing $370.91 and the most expensive (fourth) costing $888.62.

A $1387.25 three-year service contract or a $2674.64 five-year plan are on offer.
