Subaru Forester vs BMW X Models

What's the difference?

To many people, this review won’t matter. There’s a large part of Subaru’s customer base that come back knowing they’ll get a practical, capable car regardless of refinement - something the brand’s rivals can’t quite match.

But even those people will be pleased to find the new Forester is a huge step-up over the last one in many areas. Sure, it’s a little late for Subaru to be joining the hybrid game in 2025, but it’s not the only brand from Japan that’s been slow on that front, and the brand’s philosophy hasn’t always been focused on efficiency anyway.

In a vacuum, the new Forester is a great adventure companion, but anyone considering a mid-size family SUV and not requiring the AWD and clearance the Forester has on offer could do better elsewhere.

For anyone else, there’s still only one option that really ticks all the boxes - and now it’s much better than before.

Just get the petrol if you’re going anywhere that could damage a tyre.

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 new Forester is a slight departure from the characterful previous generation, and to this writer’s eye that’s to its detriment. It’s not unpleasant to look at, but it doesn’t look so much like a Forester anymore.

I wouldn’t be the first to say it looks like it had at least one pass through the North American Ford design centre, but even putting that aside, the rounded front is a less interesting design treatment than we’re used to seeing from Subaru.

Its side profile shows off its boxy, practical nature, however, and from the rear it looks much more Subaru-like than from the front.

In Sport guise, particularly, the Forester’s bronze trim and wheels are a decent give-away that the brand was going for a more premium look.

Inside, the Forester doesn’t look enormously different from the last generation, especially when it comes to buttons, shifters, and the big vertical 11.6-inch touchscreen, the latter right out of other Subaru models that have been around a while.

But perhaps that was deliberate, because some of the new Forester’s best features are those that follow the notion of ‘if it ain’t broke, don’t fix it’.

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.

Perhaps the best selling point for the new Forester is that it hasn’t changed a whole lot inside. It’s spacious for its class and has physical buttons for a lot of things, while making sure the key controls like climate are always accessible on the touchscreen without needing to navigate through menus.

The steering wheel and gearshift look familiar and the general layout of the Forester seems to follow the brand’s established pattern of convenience over anything that could be annoying or complicated.

The software on the big screen is the same as any recent Subaru SUV with big buttons and a simple menu structure that means you rarely get lost. It’s not cutting-edge, but it works, much like a lot of the elements of this car.

The seats are comfortable and the seating position and steering wheel adjustment work well regardless of grade.

One element of the interior that works particularly well is visibility. Subaru made the headrest a little narrower to assist with shoulder checks and make looking over to the back seat easier. The result is a clear view, not only of the interior but also through those annoying side angles your wing mirrors might miss.

The back seat is also plenty spacious, with ample knee, foot and hip room in the second row’s outboard seats. Head and shoulder space is also fab. There’s little risk of feeling cramped in the back, even for a proper adult, especially if there’s a sunroof for that extra light.

Behind the second row, there’s 496 litres of boot space in non-hybrids, and 484L in hybrid variants, plus a switch in the boot to drop the second row from the tailgate.

That allows for 1174L and 1162L in petrol and hybrid models, respectively, though a big downside for the hybrid models is the lack of spare wheel, just a repair kit.

No spare tyre in a car you expect to be able to take off-road isn’t good enough, and it’s the key reason the Forester doesn’t score a full 10 for interior practicality. A shame, because the rest of the cabin is built for ease.

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.

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.

Both Forester drivetrains use the brand’s existing all-wheel drive tech and a continuously-variable transmission, but the hybrid does something Subaru is keen to point out its rivals’ don’t.

The petrol version is powered by a (136kW/247Nm) 2.5-litre naturally aspirated flat-four ‘boxer’ engine that's largely unchanged.

The hybrid consists of the same type of engine with different valve controls and lower outputs of 121kW/212Nm. 

The key part is it’s assisted by a 90kW electric motor that, rather than being mounted to the rear axle and engaging when traction is needed, is placed before the transmission and sends electric power to all four wheels. Total outputs for the Hybrid variants are 145kW and 276Nm.

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.

Subaru claims the Forester drinks 7.9L of petrol (minimum 91 RON) per 100km or 6.2L/100km in hybrid guise.

The latter's a bit of a let-down given Toyota’s RAV4 hybrid in AWD guise comes with a 4.8L/100km claim and that system's been around for ages.

Both Foresters have a 63-litre fuel tank, so could theoretically travel a maximum 797km (petrol) or 1016km (hybrid). 

Don’t expect to manage that in real-world driving, though. The trip computer reading for the last car I drove on test (a hybrid) was 7.8L/100km after a mix of highway and off-road running.

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.

On paper, the new Forester hasn’t changed to a great degree. With that engine and the late-ish introduction of a proper hybrid system, you might expect the Forester to be undercooked. 

Sure, Subaru is playing catch-up and it would be a fair to say adding a hybrid grade to its mid-size SUV in 2025 puts it behind the curve, but Subaru is leaning into its niche.

Subaru’s very happy about being able to claim the Forester is the only hybrid mid-size SUV on sale where the one hybrid motor drives all four wheels mechanically thanks to its 'symmetrical' all-wheel drive system. Then there’s the "class-leading" 220mm of ground clearance.

But as well as being capable off the road, the Forester needs to be a decent day-to-day companion. Fortunately, it’s both.

The new Forester’s road manners are a surprising step-up over the previous generation’s, which felt soft and agricultural at times.

Subaru touted the new car's incremental improvements, but behind the wheel it feels like they add up to a far superior experience. The Forester is still a little noisy - mainly wind and road noise - but many of the elements that were once a let-down are much more refined.

The CVT doesn't complain so much when called upon to pick up the pace, and the steering feels much sharper. The former could be down to a huge increase in sound-shielding, the latter likely due to Subaru’s use of the dual-pinion steering system borrowed from the WRX.

Subaru says it “reduces mechanical resistance and eliminates unwanted feedback from the motor”. It seems to have done exactly that.

Perhaps most noticeable is the suspension, which feels more tied-down and stable than before, without sharpening up too much and becoming uncomfortable. Subaru says revised spring rates, better under-body aero and a more rigid chassis all contribute.

The hybrid and petrol have different suspension set-ups, the latter feeling softer in terms of damper response but still far more confidence-inspiring than the previous-gen Forester.

It all comes together to create a driving experience that’s easy and comfortable at traffic speeds and fun and engaging at high speeds on, for example, the smooth winding back-roads of New Zealand’s South Island.

The problem for Subaru is that despite having introduced a new hybrid system, the petrol-only Forester is just as good from behind the wheel. The advantages the hybrid brings in terms of efficiency will be a draw for some, but in terms of driving dynamics the extra power and torque on offer is probably not worth the extra outlay.

Then there’s the lack of a spare wheel… which should be a requirement when you’re off sealed roads. The gravel and mud of the Canterbury region didn’t faze the Forester, though, and we put the mid-size SUV through its paces harder than most owners realistically would.

Deep mud ruts, creek crossings and jagged rocky trails were all traversed easily and comfortably, especially considering the standard road tyres fitted. 

None of the test cars were stuck due to either negligent road testers or lack of mechanical ability on the Subaru’s part, though two cars on test did succumb to an excess of water in the engine bay and went into a safety shut-down mode once we arrived back at the end of the off-road trail.

We asked Subaru for an explanation and we were told it’s a feature that saves components like the cooling fan from water damage.

“Two vehicles experienced this due to the nose being submerged from entering the water crossing at the incorrect speed and/or entry line… if water enters the engine bay at a sufficient level, a protective fuse is designed to engage to safeguard the radiator fan motor.

“This system functioned exactly as designed. Despite this, the vehicle continued to perform as intended, enabling the driver to complete the off-road course and return safely to the Homestead. 

“After cycling the ignition, a warning light alerted the driver, and the engine shut down automatically to prevent any potential damage. This sequence is outlined in the Owner’s Manual. This is a built-in protection protocol and not a fault.”

A replacement fuse meant one of the vehicles “resumed full operation,” a Subaru spokesperson added.

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.

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.

Subaru‘s five-year, unlimited kilometre warranty is behind the curve for mainstream brands with many offering between seven and 10 years, but its eight-year/160,000 kilometre hybrid high-voltage battery warranty is par for the course.

Servicing intervals are every 15,000km or 12 months, with servicing pricing locked in for the first 75,000km or 60 months of ownership. Total cost over this time is $2299 for either drivetrain, with the cheapest service being $347.95 and the most expensive $679.30 (at 60,000km or 48 months).

Subaru also offers 12-months complimentary roadside assistance.

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.
