2023 BMW 3 Series vs 2022 BMW X3

What's the difference?

I thoroughly enjoyed my time in the BMW 320i M Sport. It’s fun to drive and I felt connected to what the car was doing on the road. The harder ride may not appeal to some but I didn’t mind it. The cosy back seat and boot mean it will probably suit a smaller family best and one which doesn’t have to worry about carrying a lot of gear around regularly, but it suited my needs just fine.

I reckon this is a car for those drivers who don’t want to compromise on performance but still have a kid or two. If you’re after the cushioned comfort of a Merc, this won’t appeal but I didn't want to give this one back and happily give it a firm 8/10.

My son liked the sports car looks and enjoyed the amenities in his row. He gives it a 10/10.

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.

Sharper than its predecessor, the new 320i has LED everything with the rear lights being longer and curving around to the sides of the car.

The classic 'kidney' grille is darkened and more pronounced, with the black panelling extending to the rear to create an unapologetically sporty presence. A presence that’s accentuated by the twin exhausts.

The batcave interior with its black headliner, black seats… black everything, looks smart and stylish.

You do have a fair bit of harder touchpoints throughout but the customisable ambient lighting helps to soften the overall effect.

With its 2068mm width, 4709mm length and 1435mm height, the sedan makes its presence known without feeling cumbersome to manoeuvre. Urban dwellers need not fear their local car park!

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.

For such a sleek looking sedan, it’s generous up front with plenty of head and legroom.

You can adjust the seat to sit quite low and both front seats have extendable under-thigh supports, which should excite taller drivers. 

My 189cm (6’2”) brother has the 328i and is very comfortable but taller front passengers will encroach on back seat passenger comfort.

The front seats are quite firm on the backside, they also lack adjustable lumbar support, so expect to stretch the kinks out on a longer trip.

The amenities and tech feel well thought out and easy enough to use. The 12.3-inch touchscreen multimedia system looks great and has the best-looking graphics I’ve sampled.

The BMW system is intuitive to use once you get used to it. If you’re not interested in using the touchscreen, you can also utilise the rotary-wheel for menu selections.

There’s also Bluetooth connectivity, wireless Apple CarPlay and Android Auto plus built-in satellite navigation.

The 12.3-inch digital instrument panel is customisable and the information displayed simply but you won’t really look at it because of the head-up display.

Front occupants enjoy a wireless charging pad for their smart phone, a USB-A and USB-C port plus a 12-volt socket. Rear passengers get a couple of USB-C ports, too.

The storage is good for this size sedan but overall passenger room takes priority, but the glove box and middle console will suffice for everyday use.

While it may not excite others, I love the big bottle holders in the doors. They’re large enough for my big 1.5L bottle and angled for easy access. These are found in the rear doors as well.

Back seat passengers enjoy climate control, directional air vents, two cupholders, netted map pockets and reading lights.

My six-year old was happy with the amenities and lower ground clearance because he felt comfortable and had his independence.

The boot offers a good capacity of 480L and the aperture isn’t too narrow, so you can comfortably access items if they roll to the back.

I had plenty of room for my little family’s needs but if you’re a larger family, you may need to get strategic with gear storage.

Being a base model, you do miss out on a powered tailgate, which is a shame but not too much of an issue given this is a sedan and the lid isn’t heavy.

There’s also no spare tyre or even a puncture repair kit but you have run-flats, so you should be able to limp to a service centre if need be.

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.

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 320i M Sport has the ‘baby’ engine in the 3 Series line-up but the 2.0-litre, four-cylinder turbo-petrol powertrain still delivers on power with a maximum output of 135kW/300Nm. 

This is a rear-wheel drive and has an eight-speed auto-transmission which delivers very smooth gear changes.

Despite having the smaller engine, it can still go from 0-100km/h in just 7.4 seconds.

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.

In a world with rising fuel prices, the efficiency of this decently powered sedan should excite you.

The official combined fuel cycle is 6.5L/100km. Real world testing saw my figure at 7.4L/100km after a mix of open-road and urban driving this week.

I thought that was great for how hard I drove it and for the power, you won’t be wincing when you put your foot down. I would expect it to be higher in an urban setting.

The 320i has a 59L fuel tank and based on the official combined cycle figure, you should get just over 900km of driving range, which is great, especially if you do 'roadies' like me!

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.

There's a lot that I like about how this performs but a highlight is how eagerly the car responds when you accelerate.

However, it’s not unbridled power. There’s no bucking at the front or shuddering through the steering wheel. It’s controlled but still very fun.

The lower centre of gravity and coupe-like height of this does mean it handles corners well and the bolstered seats hold you firmly into place, meaning you can be free to drive this a little harder than you might normally. Which I did and can confirm it handles itself well.

This has the M Sport suspension, which means it’s stiff, but you feel very connected to the road.

You do get a lot of talk-back from bumps in the road but unless you hit a big pothole, you never feel rattled by them.

But it is a harder ride than other luxury models, which doesn’t bother me as I like the handling, but if you want limo-like comfort, look elsewhere.

The cabin is very nice to spend a lot of time in and relatively quiet, even at higher speeds.

The 11.4m turning circle and sleek dimensions makes it very handy to park, even in tight car parks. The nose is long but the front and rear parking sensors take out any ‘will I make it’ moments and the super clear reversing camera is great. 

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 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.

The 320i comes with a five-year/unlimited km warranty, which is standard for this class.

You can choose between a three- or five-year capped-priced servicing plan. The five-year plan costs just $2150, or $430 a year, which is competitive for this class.

Like other BMWs, servicing intervals are condition-based, with the car letting you know when it needs to be serviced.

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.
