What's the difference?
Big fast SUVs have long been a guilty pleasure of mine. My brain has been telling me for years, since the first time I drove one - the first-gen Audi SQ5 - that they're silly and wasteful and 'not my kind of car'.
The Europeans - and latterly, the Americans - seem to be playing to an audience of me, convincing my prejudiced head that my try-anything heart is right: over-engined, jacked-up, stiffly-sprung family wagons are as much fun as anything else.
The X3 M is BMW's first full-fat M version of the X3, a car that has never really fired the imagination until this third generation. First we got the very good X3 M40i, now we have a 375kW, twin-turbo straight-six screamer, the M Competition.
BMW was once a brand most known for its range of sporty sedans and coupes. In the last 15 years, though, things have literally changed the face of the Bavarian juggernaut.
If its X3 SUV range is anything to go by, things are set to change a lot more before the brand has settled into its new comfort zone of electrified SUVs.
You see, unlike most of its rivals, the X3 is now offered in petrol, diesel, plug-in hybrid, and as the fully-electric iX3. This allows BMW to hedge its bets over various drivetrains, but it’s also one of the first automakers to have such a comprehensive offering for a single model.
For this review we’re looking at the xDrive30e plug-in hybrid model to find out if BMW’s PHEV offering has what it takes to win some premium dollars from the likes of Volvo, Mercedes, and Lexus, all of which have added hybrid rivals with plugs in this space in recent years.
As much as I love the mental GLC63 - complete with V8 bellow - the X3 M is the one for drivers. While that's a silly thing to say on the surface - what 'driver' is going to buy an SUV? - this is the new reality. We love these things and they're not going away.
While it may not be quite as comfortable as any of its competition or have the V8 cachet of the Jag and the Merc, it still takes the fight to them in what is easily the roomiest and most practical in this niche part of the segment. And it's an enormous amount of fun.
The X3 xDrive30e is a sporty SUV with fantastic ride quality and slick driving characteristics, although its specs seem a bit behind on the electrified front despite it being the most expensive PHEV of its peers.
This leaves it with an odd split personality of being particularly limited to tight city driving to make the most of its EV features, while its engaging nature beckons more to the open road than some of its rivals. A jack of two worlds perhaps, but a master of neither.
The third-generation X3 is by far the best-looking and isn't as badly blighted by BMW's current oversized, hatchback-straining grilles. It's not small, no, but in the flesh, it looks fine.
The usual M accoutrements are present, with new front and rear bumpers, skirts and a whopping set of 21-inch alloys. It looks different and marginally more aggro than the M40i and just enough so a vaguely interested observer will notice.
A quick look at the rest of the similarly-sized hard-and-fast SUVs reveals a similar approach.
The cabin is largely unspectacular, as is the BMW way. The X3's interior pre-dates the current X5, X7 and 3 Series which are rather more attractive and packed with newer tech.
The seats add some serious excitement, they're a proper set of M seats, complete with the slightly naff light-up X3 M logos in the backrest. But it's predictably well-made, is very comfortable and is full of nice materials.
The X3 is iconic BMW, having come to be the face of the brand for many buyers, the mid-size SUV exemplifies the Bavarian marque’s ‘kidney grille’, sharp and tall lines, and strongly defined body.
It’s part dainty luxury car and part buff Germanic tourer in equal measure. Suffice it to say fans of the brand will love it, but it’s not going to make converts of anyone else.
Newer design elements which adorn the X3’s body include the striking tail-light design, and little plastic fills below which combine with its contrast bumper and dual-exhaust ports to make for a sporty looking SUV.
The wheels look enormous and add enough chrome to the picture to keep it looking sleek, while subtle badgework has always been a hallmark of a good BMW.
BMWs have always had a relatively minimalist take on the interior design, and overall this is a space in which progress has been made at a glacial pace throughout the brand’s history, wild 7 Series limos being the exception to the rule.
This means the X3 gets the iconic centre-panel, ever so slightly oriented to the driver which houses the two centre air vents and climate control buttons, and a small panel below which houses the volume knob and shortcuts for the radio.
The digital revolution has very much come to the interior of this SUV though, as the top of the dash is adorned with a single enormous panel, and a second one set in the instrument binnacle in a classic fashion. It will all be quite familiar, even if you’ve skipped a BMW generation or two.
The wheel is a key touchpoint, clad in a lovely soft padded leather but with a chunky three-spoke design and massive notches at 10 and two for you to rest your hands on.
I don’t like this wheel in the brand’s more dainty sports cars like the Z4 where it feels too big, but it definitely feels at home in the X3.
Quality materials with plenty of soft-touch plastics and leather trims extend their way into the door, while the software is appealing in its design and fast to respond; clearly backed by strong hardware.
A final thing worth noting is the X3 has one of the more dated interiors in the BMW range. While it has been augmented with digital upgrades over the years, it doesn’t feel as contemporary as the incoming range of cars with the next-gen design elements. Take a look at the iX’s spectacular interior for what you’re missing out on.
This X3, if you need reminding, is bigger than BMW's first SAV (ugh), the X5. That means plenty of room up front, heaps of legroom for most in the back and enough room for five aboard.
Front seat passengers score a pair of cupholders with a cover and the centre rear armrest has two more for a total of four. Add to that bottle holders in each door and your beverage holding capabilities are pretty standard.
The boot starts at an impressive 550 litres, almost tripling to 1600 litres when you drop the 40/20/40 split fold seat. You get a good flat load space when you do that, too.
The X3 is reasonably large on the inside, with a commanding road view and healthy space for an adult in both front seats. The tall roofline leaves plenty of room for someone my 182cm height, while leather-clad soft-touch finishes are present for your elbows and knees.
There’s a large bottle holder and thin bin in each of the front doors, and a wide centre console with a further two bottle holders with adjustable ridges and a large storage bay suitable for a phone below the climate cluster.
This area also houses a USB port and a little shaped notch for you to place the key, and the whole area can be covered over with a retracting lid.
Like all BMWs there are well hidden shortcut buttons for many of the functions which integrate into the design, and there’s a multimedia screen function for most functions, too, controlled through the centre dial system, or via touch.
It’s nice to have both, unlike some Mazdas which use a similar control system, but force you to rely on the dial.
The second row looks a bit flat from a distance, but you do sink into the leather-clad seats nicely, and unlike some rivals in this category, the second row is fixed and not on rails.
Room for a 182cm tall adult is decent, with a little more than adequate knee room and excellent headroom.
The leather trims continue, and true to the sense of being a premium brand the intruding piece of wheelarch is also clad in padded leather. No touching plastic in here.
A single bottle holder appears in each of the rear doors, with a further two in the drop-down armrest, and there’s a netted pocket on the back of each of the front seats.
Rear passengers get their own climate zone with an independent control panel as well as a 12V outlet and two USB-C ports.
Luggage capacity in the boot is rated at 450-litres (VDA), significantly down on the combustion versions of this car. Note in the pictures the stepped boot floor, which is adorned with a chrome trim piece for some reason, as though the car is always reminding you of the lost room.
Still, the squared-off space managed to fit our three-piece CarsGuide luggage set with relative ease and room to spare. There is a thin and narrow slot under the boot floor which serves as a location to place your charging cables.
For $157,900, before on-road costs, you may think this car should be absolutely loaded with stuff. And it is. Whether that's enough is up to you, but the price is about right for its segment.
It's worth remembering we only get the up-spec Competition version, BMW saw no point in offering the 'normal' version nobody was going to buy.
For your cash you get 21-inch alloys, multi-zone climate control, ambient interior lighting, keyless entry and start, active cruise control, electronic damper control, digital instrument cluster (not the new 'Live Cockpit'), sat nav, auto high beam, auto LED headlights, launch control, leather seats and steering wheel, electric front seats, head-up display, auto parking, power everything, auto wipers, huge panorama sunroof and a tyre repair kit.
The big central screen features BMW's iDrive, controlled by either the rotary dial or via touchscreen. It's a belter of a system and I reckon it's still the best, although you have to pay for Apple CarPlay - this remains controversial and I wonder how long the company will persist.
This plug-in version of the X3 sits near the top of the X3 range, eclipsed only by the M40i performance variant and the fully-electric iX3. This means a starting price of $104,900, which initially doesn’t bode too well for the BMW given its rivals can be had at a lower price.
The similarly-specified Mercedes-Benz GLC 300e starts from $95,700, the Volvo XC60 Recharge starts from $97,990, and the impressively-specified newcomer on the block, the Lexus NX450h+ is the best value of the lot at just $89,900.
You’ll note all of those plug-in models are of the higher specification in their respective ranges, with each manufacturer clearly trying to draw buyers into this tough-to-understand tech by compensating the curious with gear which would otherwise be optional on a pure combustion car.
There are technical elements which play into the value of each when it comes to the PHEV drivetrain which we’ll look at later in this review (it’s particularly important when it comes to how you use and park your car) but we can at least say the X3 xDrive30e comes with a healthy amount of equipment.
Most of this matches the xDrive 30d below it, including large 20-inch alloy wheels, a set of M sport trims, brakes, and adaptive suspension, 'Vernasca’ leather interior trim, adaptive LED headlights and LED tail-lights, ambient interior lighting, a 12.3-inch multimedia touchscreen with wireless Apple CarPlay and Android Auto connectivity and built-in navigation, a second 12.3-inch screen for the ‘Live Cockpit’ digital instrument cluster, tri-zone climate control, a head-up display, electrical adjust for the driver and front passenger seats, a 12-speaker sound system, and the functionality for over-the-air updates.
The specific inclusions for the xDrive30e include free optional paint colours, a panoramic sunroof, lumbar support in the driver’s seat, front seat heating, wall socket to Type 2 and Type 2 to Type 2 public charging cables, and specific i-branded interior elements.
Normally the sunroof and premium paint are part of a $5400 option pack, while the heated seats, steering wheel, and lumbar support seats are normally a $1200 option, meaning the PHEV variant only leaves you $3400 and a set of ‘Laserlight’ LED headlights worse-off than if you were to apply the same options to the xDrive30d.
Not bad considering it also packs a 12kWh Lithium battery under the boot floor, and a secondary electric motor integrated into its transmission. More on this later.
The X3 M arrives from the US with a shiny new version of BMW's modular six-cylinder performance engine. While the M Performance M40i has a single turbo (B58) straight six, one tiny change to the name - from B58 to S58 - means a heck of a lot.
The S58 takes the same fundamental formula, bolts in two new single-scroll turbos, throws in forged conrods and a few other changes to boost the power to 375kW (500 horsepower) and 600Nm.
That torque figure is available across a nice wide 3350 revs, between 2600rpm and 5950rpm.
Getting all that to the wheels is the M version of BMW's all-wheel drive system xDrive and an active rear differential. The near-ubiquitous eight-speed ZF brokers the connection between that system and the flywheel and it's all impossibly smooth and feels bulletproof.
The PHEV version of the X3 pairs the brand’s usual 2.0-litre four-cylinder turbocharged petrol engine with a relatively powerful electric motor integrated into its eight-speed torque converter automatic transmission.
On its own, the engine produces 135kW/300Nm, while the electric motor is capable of punching out 80kW/265Nm. When working together, the EV components can provide a further electrified boost, for a total of 215kW/420Nm, allowing for a 0-100km/h sprint time of 6.1 seconds. This makes the 30e only slower than the M40i and 30d variants in the rest of the X3 range.
The xDrive30e is capable of travelling up to 135km/h under electric power alone, with a surprisingly small 12kWh battery delivering around 41km of pure EV range.
As the electric motor is mounted in the transmission it is capable of driving all four wheels via the brand’s 'xDrive' system with torque vectoring.
Somewhat amusingly, the German documentation for the X3 includes a section for “off road characteristics” (I suppose it is an SUV after all…) and for those interested the xDrive30e can ford at up to 500mm depth, has an approach angle of 25.6 degrees, a departure angle of 22.8 degrees, a breakover angle of 20.0 degrees and a ground clearance of 204mm. Enjoy the trails.
The official fuel sticker quotes a mightily impressive 10.6L/100km. No, not great for a mid-sized SUV but pretty good for one with five hundred horses under your right foot.
The reality, of course, is different but not unexpectedly so - a week in my hands in the suburbs and a cobweb-clearing early morning run delivered a 14.1L/100km average. Again, not bad given the kind grunt that's on tap.
Here’s the tricky bit. The X3 xDrive30e has an official combined fuel consumption of just 3.2L/100km, but this will depend heavily on how you drive it.
You see, the BMW hybrid system is very keen to drive under electric power alone, even in the so-called ‘hybrid’ driving mode. This will mean you will extinguish the battery’s 41km driving range (or 35km according to our test vehicle on a full charge) quite quickly, whether you like it or not.
Plus, the charging capability is a bit slow. At 3.7kW, the PHEV X3 charges its 12kWh battery up in 2.6 hours on a faster public outlet or garage wall box, or around five hours on a wall socket.
To put it in perspective, the Lexus NX 450h+ showed me nearly double the amount of electric driving range on a single charge (65km as-tested) and was capable of charging up at a rate of 7.2kW, meaning a two hour flat charge for twice the range on a public outlet.
The summary boils down to: If you charge up at home, this won’t be as much of a problem, if you need to rely on public charging, it could make a difference to the PHEV you pick.
You can prolong the life of the battery using the ‘battery level’ mode which lets you set a target for battery life and have the car switch to primarily combustion at that point.
This can come in handy if you have a lot of open-road driving, and want to conserve the battery for driving around town where it is most efficient.
On my week with the car I saw an impressive consumption figure of 2.2L/100km according to the trip computer, under the official number, while my energy consumption came in at 20.7kWh/100km against a claim of 16.4kWh/100km. I did make sure to charge the car up at every opportunity, however.
Like all BMWs the X3 xDrive30e requires mid-shelf 95RON unleaded fuel, and has a 50L fuel tank despite the addition of its high-voltage battery.
One of the things I love about BMW is the company's ability to produce a car that on one hand is so normal and competent for the every day but also produce a version that is completely doolally.
The fine folk at M obviously involve themselves from day one so that when they get a finished car they can get cracking on making it properly fast. Obviously, quite a bit has to change for that to happen.
The X3 M is very stiff. Pop the bonnet and you'll see a piece of whatever the metal equivalent of four-by-two keeping the two sides of the car apart.
This is something M does whenever it gets a vanilla BMW, as it has with the M2 and outgoing M3 and M4 pair. To name three. The difference from the driver's seat, when compared to, say, the M40i, is immediate.
The steering is super-responsive, the front of the car reacting incredibly quickly given the X3 M's two-tonne weight.
Even in Comfort mode, the X3 M's ride is pretty firm. That doesn't bother me especially, nor my wife, who has a keen sense of ride quality. It never really falls over the line of being uncomfortable but it's worth knowing if you're considering this and you have to carry passengers.
If you drive around town in either M1 or M2 (in the factory settings at least), you're mad - the suspension becomes very hard and the steering too heavy. In fact, the steering in its Super Sport setting is just too heavy and uncooperative.
Once you've set it up to your liking though, the X3 M is brilliant. The S58 - soon to be installed in the new 3 and 4 Series M cars - is fantastic.
Cheerfully belting the 7200rpm redline at every upshift, barking between gears and delivering torque the way a hungry Labrador delivers a headbutt if you get in between it and food, the straight-six is glorious.
The 4.1-second sprint from 0-100km/h is only part of the story. Not many cars can cover ground so quickly and fewer still SUVs of this size and weight can do it with such precision.
When you turn the wheel on the X3 M, the front goes where you want it, instantly. All that under-bonnet bracing prevents the front flexing and shimmying, which is the enemy of going fast. So that sorts out getting into the corner. The best thing is you can push through corners and slingshot out the other side, riding that huge torque slab, the rear wheels doing most of the work with the occasional wriggle to keep you smiling.
A good chunk of the applause goes to the way the xDrive all-wheel drive system and its 'M Active' diff at the rear work together in Sport+ mode.
As colleague Steve Corby discovered at this car's clay-pan launch, the front wheels aren't doing much of the driving when you've turned it all up to 11 in '4WD Sport'.
When the road goes from straight to twisty, the excellent brakes come in to play, hauling the car down from big speeds without complaint. Even better is that in normal driving, they're not grabby and the pedal always lets you know what shape you're in.
One of the things I came to love most about this version of the X3 is how seamless the hybrid system is, and how unusually quiet and comfortable this car proved to be.
Sure, it’s a luxury mid-size SUV, but I came away particularly impressed with how the adaptive suspension tune pairs so nicely with the electrified acceleration to make for a sleek driving experience.
Despite its dimensions, the xDrive30e feels light and springy over bumps, filtering out the worst of the road while keeping a good level of control at the wheels.
The stock steering tune in the car’s standard ‘hybrid’ driving mode is nice and light, too, making this mid-sizer feel smaller than it really is to pilot, and you don’t feel the extra weight of the battery pack at all.
The combustion engine is so quiet it is at times difficult to tell when it enters the mix, aside from the fuel consumption meter on the dash suddenly coming to life.
It too is a smooth unit, providing partially electrically-assisted acceleration in most modes which makes it hard to tell when the transmission changes cogs. It’s as though you get the best of both worlds this way.
The car is a bit too keen to rely on its electric driving, and, as mentioned earlier, this will mean it drains its battery relatively quickly unless you take extreme measures like the battery saver mode.
The result is a car which is far better suited to shorter city-based journeys than long tours through the country. At least the turbocharged engine and BMW driving dynamics are left intact should your battery run dry.
The regen braking is mild (able to recoup a max of 20kW at any given moment), although the indicators on the dash are neat for letting you know the limit of your electric acceleration and how far you’ve travelled without using the combustion engine.
On my week with the car I managed over half the distance with the engine completely off. Think of the fuel savings.
Elsewhere the X3 offers great visibility thanks to a boxy shape with big windows, and solid electric acceleration, with decent handling, too. I’d say it feels sportier than the Lexus NX or Merc GLC equivalents, with the ride a bit more forgiving than that of the Volvo XC60 Recharge.
As an EV then the xDrive30e is notably limited, but as an SUV which threads the needle of being both engaging and comfortable, it’s possibly the best of the current premium mid-size SUV PHEV pack.
The X3 M rolls out the door of BMW's North Carolina factory with six airbags, stability and traction controls, front and rear parking sensors, around view camera (including reversing camera), forward and reverse AEB, blind spot sensor, lane departure warning, lane keep assist, reverse cross traffic alert, speed limit recognition and tyre pressure monitoring.
There are also two ISOFIX points and three top-tether restraints.
The X3 scored a maximum five ANCAP stars in 2017.
The X3 range has a healthy list of standard active safety equipment, with items like freeway-speed auto emergency braking, rear auto emergency braking, lane departure warning with lane keep assist, blind-spot monitoring with rear cross-traffic alert and adaptive cruise control.
It also has a speed limit assist function and a rather cool parking suite which gives you a 3D surround picture of the car capable of adjusting to particular angles when objects get close.
The X3 has the standard array of dual front, dual side, and dual head curtain airbags, as well as seatbelt pre-tensioners. There are dual ISOFIX points on the outboard rear seats, or three top-tether mounts across the rear row.
The base X3 offerings have a maximum five-star ANCAP safety rating to the 2017 standard, although this plug-in hybrid variant was not available at the time.
BMW offers a segment standard, but increasingly mean-looking, three years/unlimited kilometre warranty. It's not just BMW, though, it's all of the premium Germans. You do get three years roadside assist into the bargain and you can pay to extend the warranty, too.
You can pre-pay your servicing, with a five-year/80,000km Basic package for $3685. If you think you're going to give your X3 M a proper walloping you can opt for the the 'Plus Package'. For a not-inconsiderable $8173.
BMW will cover your brake pads and rotors for the same period as the Basic package.
Service intervals are variable because, as ever, BMWs tell you when they need a trip to the dealer.
BMW languishes with just three-years of warranty coverage. The brand along with its Mini subsidiary has become a notable laggard in the space now, its last remaining Audi rival has moved on to match the five-year and unlimited kilometre promise of its VW parent.
Servicing on BMW models is ‘condition dependent’ meaning the car’s computer will keep track of when servicing needs to happen based on how the car is driven and other factors.
A five-year ‘basic’ service pack is available inside the first 12 months of purchase and covers visits inside this period or 80,000km whichever occurs first. It costs $2010, or $402 a year.
