Subaru Crosstrek vs BMW X3

What's the difference?

It’s not perfect, in fact, the Crosstrek has a few factors that would probably turn off groups of buyers at a time, but Subaru knows its audience isn’t ‘everyone’.

Subaru customers aren’t trying to get their fuel efficiency below 4.5L/100km, nor find the car with the most luxurious interior. They’re looking for a practical Jack or Jill of all trades, which the Crosstrek does rather well for its segment.

Few small SUVs are as agreeable on rough and unsealed roads without sacrificing suburban comfort, while its features list is practical and provides plenty for the money.

Unfortunately, the hybrid system is a little underwhelming, and if it’s the main draw of the Crosstrek for you, it could be worth considering the less expensive ($38,590) Hybrid L or even a hybrid rival like the Toyota Corolla Cross or Mitsubishi Eclipse Cross.

If the all-round ability of the Crosstrek is the draw, however, the non-hybrid L is still an excellent offering and doesn’t use a lot more fuel than the Hybrid - plus it’s several grand cheaper at $41,490.

The Crosstrek is great for active people who need a bit of flexibility in one car but for the vast majority, the hybrid probably isn’t the sweet spot in the range. However, that won’t hinder the Crosstrek as an overall model, its popularity is already proven, and the option of a Hybrid puts Subaru a little closer to the eventual necessity of electrification.

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.

Perhaps unsurprisingly, the new Crosstrek looks an awful lot like its a development of the Subaru XV.

Which, given the latter’s popularity, is a very good thing.

While there are a lot of similarities, especially when it comes to some of the more rugged elements, the Crosstrek still manages to look quite new.

It’s rugged without having too many ‘busy’ design elements and it even looks at home in inner-city suburbs. 

Of course, its raised body and cladding are mostly for practical reasons, but it gives the small SUV an adventurous aesthetic that separates it from city-focused rivals.

As essentially a high-riding development of the Impreza hatch, its size and proportions also make it look more like a ‘big car’ than a small SUV.

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.

Practicality is pretty much a staple of Subaru as a brand, so it should be a huge surprise that it feels that way from the driver’s seat.

The interior doesn’t look futuristic, but it does look functional. 

For example, even though the centre of the dash is all screen - and we love buttons for climate controls around here - the controls for air conditioning and temperature are at least always present on the screen, no sub-menus needed.

The phone charger is large enough for even very tall phones (looking at you, Samsung Galaxy S20 Ultra, pictured), and it’s out of the way to minimise extra digital distraction.

The steering wheel’s buttons, while many, are all clear and simple, as is the iPad-like icon layout on the multimedia screen.

Storage in the front is miles ahead of the rear seats, a large central bin with two cupholders, a big glove box, and decent space for water bottles in the door cards. In the rear, two central cupholders in the armrest and a small space in the door.

But there is a decent amount of space for an adult to sit in the rear, even if the sides of the roof are a little close to the head. It’s a little like the front, where the seats are supportive and easy to adjust to a comfortable position.

Further back, the boot space is a relatively small 315 litres, though its slightly larger than the 291L the petrol versions come with - that extra space likely swallowed by a spare tyre in the petrol versions, as opposed to the smaller batteries taking up some space in the hybrids.

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.

This is perhaps the part of the review you’re most interested in - as well as the following sections on efficiency and maybe driving - if the ‘Hybrid’ part of the Crosstrek Hybrid S’ name brought you here.

Like its design and interior, the engine will be familiar to anyone who has owned or driven a relatively recent Subaru - a 2.0-litre flat-four petrol engine good for 110kW/196Nm - which means it makes a little less than the standard petrol variant’s 115kW.

However, the electric motor is capable of its own 12kW/66Nm outputs, though Subaru doesn’t supply a claimed total maximum for the whole powertrain.

Drive is transferred to all four wheels - it is a Subaru after all - via a seven-step continuously variable transmission (CVT).

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 Crosstrek Hybrid will sip 6.5L/100km on the combined cycle, which isn’t enough to blow anyone away, even when you take into account the extra fuel needed for permanent all-wheel drive. The AWD Corolla Cross Hybrid comes with a claimed 4.4L/100km.

Compare this to the 8.5L/100km reading the Crosstrek returned after our time with the car, mostly with a (somewhat unkind) mix of inner-city and semi-rural backroad driving, and it’s clear the Crosstrek isn’t one of the most frugal cars in its class.

More highway driving would certainly have lowered the figure - we’ve achieved 8.0-litres on previous testing with a non-hybrid Crosstrek - but perhaps being top of the charts for efficiency isn’t necessarily what Subaru buyers are looking for.

Of course, the Crosstrek Hybrid S employs a couple of features to avoid using fuel where it can be avoided, such as auto stop-start and its (relatively mild) electric system taking over when mostly coasting or the engine isn’t required.

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.

Two things stand out after a short stint behind the wheel of the Crosstrek Hybrid, and both become more cemented over time.

The first is that the ‘Hybrid’ part of the ‘Crosstrek Hybrid S’ isn’t quite as prominent in its real-world impact as it is in its name.

The 110kW engine doesn’t feel like it’s being massively helped along by any electric assistance, and the electric motor is very rarely doing the work by itself, as you’d find in any hybrid from Toyota or Honda.

That’s a shame, because the Crosstrek could do with a little extra oomph, if not for getting up to speed then for avoiding thrashy engine sounds under acceleration.

The CVT, while not necessarily detrimental to its performance, doesn’t help with that.

But balancing that out is a chassis and platform that’s engaging and predictable - and that’s predictable as a good thing - making the Crosstrek pleasant to pilot.

Its controls like steering and braking are nicely weighted for low speeds, commuting, and for more spirited driving, while the suspension and chassis handles surfaces from smooth suburban roads, to city tram tracks, to unsealed roads with ease, soaking up bumps and shakes nicely.

If you’re noticing a theme in this review, it’s that Subaru doesn’t seem to be chasing any ‘best at’ metrics in favour of giving the Crosstrek the ability to do a range of different driving and being at least satisfactory in any given area.

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.

The Crosstrek is covered by Subaru’s five-year/unlimited kilometre warranty, with servicing intervals coming up every 12 months or 15,000km under Subaru’s five-year capped-price servicing.

Subaru also adds 12 months of free roadside assistance.

This is all fairly standard in the industry, though some brands like Kia and MG offer seven-year warranties, or there’s Mitsubishi with a 10-year warranty (even if it requires certain conditions to be met during the decade).

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.
