Kia Sorento vs BMW X2

What's the difference?

The Kia Sorento GT-Line PHEV is a sumptuously equipped seven-seater that delivers comfort, tech and an easy-going drive. It presents well on the surface, and for the right buyer (one who can make the most of its plug-in capabilities ) it could be a smart, low-emissions option for family life.

But for all its polish, it doesn’t quite do enough to justify itself as the best Sorento in the range. The electric-only driving range isn’t especially generous, and the higher price tag , combined with its lower towing capacity, may leave some families wondering whether the diesel variant is the more practical choice.

It’s not a bad car by any means, but the flagship GT-Line PHEV feels more like a stepping stone than a standout.

There is little doubt the new X2 represents a vast improvement over the original model. The design alone gives it a lot more presence. 

More interior and boot space also helps widen the SUV’s appeal and the significant tech updates are welcome.

It is on the pricey side and there are a few too many options that should be standard. 

However, the M35i is hard to ignore as a sporty premium crossover, and the iX2 xDrive30 is the sort of electric SUV that should worry Volvo.

They both have their own distinct flavours, so there’s no dud in this line-up. Of course, we will hold final thoughts for the local launch when we can drive all four grades. But until then, it’s a welcome return to form for the X2.

The Sorento looks exactly how a modern SUV should - confident, capable, and well-proportioned without feeling bulky. It wears its size well, delivering that commanding presence families often want in a seven-seater, without coming across as too aggressive.

I especially like the 19-inch alloy wheels as they suit the vehicle’s stance perfectly. I also like the striking LED lighting signatures front and rear, which really come to life after dark.

Step inside and the cabin strikes a neat balance between tech-forward and user-friendly. You’re greeted by dual 12.3-inch widescreen displays that make a strong first impression, but thankfully Kia hasn’t gone all-digital! You still get physical buttons and dials where they matter, making everything feel intuitive and easy to navigate.

Material quality is a highlight. There’s quilted Nappa leather upholstery, soft-touch surfaces throughout, and even a luxe suede headliner. These premium touches, coupled with the panoramic sunroof, lift the ambience and it's a cabin that feels genuinely upmarket, but not at the cost of family friendly functionality.

The second-gen X2 looks very different to the original from 2018. That first X2 had a squat stance, looked more like a hatchback than an SUV, and the glasshouse appeared as though it had been squished into the body of the car.

The 2024 X2 adopts a similar design philosophy to the X4 and X6 - swoopy, coupe-like roofline and liftback, and bold styling elements at the front and rear.

It has a much more upright, flush front end, freshly designed large kidney grille and an edgy headlight design. There’s flared wheel arches and broad shoulders at the rear, as well as a cool new horizontal tail-light signature.

The X2 has grown in size in a big way. It’s 194mm longer, 21mm wider, and 64mm taller than the outgoing model. That naturally means more space inside, too.

Inside there are big changes. The X2 adopts elements introduced by the excellent iX SUV a couple of years ago. They include the curved display, and a floating arm rest with a control panel. Some of this is also familiar from the X1.

The materials mostly look and feel like they are high quality, and there is an appealing minimalism to the overall design and layout. The chunky sports steering wheel is visually appealing, but it’s a bit too thick in my hand.

Space up front is generous, with excellent seat comfort thanks to wide seat bases, extendable under-thigh support and heating and ventilation. Getting in and out is easy, too, helped by wide door openings and a manageable 176mm ground clearance.

Storage throughout the cabin is thoughtful and abundant. Up front, there’s a large glovebox, a spacious centre console with a removable shelf, two cupholders, door bins with bottle holders, and a handy phone cubby beneath the dash.

The second row adds its own bottle holders and storage bins in each door, map pockets, four cupholders (including one cleverly placed on each door) and a removable floor shelf in front of the centre seat.

Even the third row isn’t forgotten, with a snack cubby and cupholder built into each wheel arch.

Tech-wise, the dual 12.3-inch displays look sharp, and the media system is intuitive and quick to respond. The instrument cluster isn’t particularly customisable, and I’m not a huge fan of the layout, but it displays the essentials clearly. You also get a head-up display, satellite navigation with over-the-air updates, and both wireless and wired Apple CarPlay and Android Auto.

Charging options are solid across all three rows, with multiple USB-C ports, a 12-volt socket in the second row and boot, and a wireless charging pad up front.

The second row offers ample legroom, though headroom is slightly reduced due to the panoramic sunroof. The lack of a transmission tunnel is a win for middle seat comfort, and the bench is wide enough to accommodate three child seats side-by-side. There are three top-tether points and ISOFIX anchors on the outboard seats.

Comfort and convenience features in the second row include heated outboard seats, device pockets, directional air vents, and the same handy storage and charging options mentioned earlier. My son especially loves the retractable sunblinds and the cupholders built into the door handles as they’re easy to reach and super practical. I am, however, disappointed that there’s no separate climate control zone for this row.

As for the third row, it’s best treated as a sometimes seat for adults. Access is more child-sized, and amenities are limited, but you do get directional air vents and a fan control, which are definitely appreciated.

Boot space is tight with all three rows in use, at just 175L, but that was still enough for the odd errand during the week. Fold the third row down and you get a much more usable 604L. Both rows fold completely flat, making it easy to slide in larger items, and the GT-Line includes a powered tailgate and a rare full-size spare wheel for extra convenience.

Where the previous X2 was a very small crossover with niche appeal, the increase in size for the new model means more people will be interested in it. Possibly even people with a small family.

Those increased dimensions pay dividends inside, with ample headroom up front and more than enough space across the front row, although the raised armrest console is somewhat narrow. 

The seats in both the iX2 xDrive30 and the M35i xDrive are very supportive thanks to ample bolstering, but both were also on the firm side. The iX2’s synthetic leather was slightly more comfortable than the M35i’s sports-focused front seats.

The power-adjustable seats and height- and reach-adjustable steering wheel means it’s not hard to find a decent driving position, but forward vision is impeded by a very thick A-pillar, and the letterbox-like rear windscreen in the X2 means rearward vision is limited. Good thing it has excellent parking cameras and sensors. 

Storage is decent in the X2, with room for big bottles in the door cavity, and a few nooks and large open spaces in the console. Although secure storage is limited with the armrest housing a very shallow space. I do like BMW’s phone charger setup. Rather than lying on a pad, it slots into a vertical holder that has a latch to keep it in place when cornering. The only drawback is that you can see the screen which could potentially distract some drivers.

The X2 introduces operating system nine to iDrive, which is housed in the central part of the curved display and operated by touchscreen or the controller on the floating central console. After some familiarisation, the functionality isn’t that much different to the previous version of the operating system. The main menu looks cool and is mostly easy to navigate. The sub-menu icons - of which there are heaps - look a little Microsoft Windows.

The X2 has drive modes that also interact with the interior of the car and change lighting, EV noise and more. They include Personal Mode, Sport Mode and Efficient Mode as standard, but if you opt for (and pay extra for) BMW Digital Premium, the modes extend to Expressive Mode, Relax Mode and Digital Art Mode. Some of these are quite cool, especially some of the EV sounds, but would I use them everyday? Probably not.

The clearest indication of increased space is in the second row. There’s much more legroom than the old X2, and behind my six-foot frame I had enough space with a couple of centimetres between my knees and the front seat backs. Toe room was very limited, however. 

The roof has been scalloped out to ensure more headroom, which is welcome given the extra sloping roofline.

There are a pair of USB-C ports back there, lower air vents, map pockets, decent door storage, and a centre armrest with cup holders.

The boot is sizeable, in both engine grades but you only get a tyre repair kit. There is underfloor storage for the charging cables in the iX2.

At 560 litres with all seats in place and 1470L with the second row stowed, the petrol grades have a bit more space than the iX2 at 525L (all seats in place) and 1400L (second row lowered).

In Australia, there will be four X2 grades in total - the xDrive20i and M35i xDrive petrol models, and the iX2 eDrive20 and xDrive30 all-electric models.

The iX2 xDrive 30 and the two X2 petrol grades are expected late in quarter one, or early in quarter two. The iX2 eDrive20 will follow shortly after in the third quarter.

The model grades largely mirror that of the X2’s mechanical twin, the X1, although the X1 is also offered in base front-wheel-drive sDrive18i guise as a range-opener.

At the international launch event, the two grades available to drive were the iX2 xDrive30 and the X2 M35i, so I will focus on those two models when it comes to the driving and practicality sections of this review. But I will detail elements of the whole range in other sections.

That X2 xDrive20i kicks off the range from $75,900 before on-road costs. For that you get features like a leather sports steering wheel, dual-zone automatic climate control, satellite navigation, an automatic tailgate, 19-inch alloy wheels, four USB-C ports and more driver-assistance systems and digital services compared with the previous model.

The $92,900 X2 M35i xDrive adds an extra dollop of performance but also includes 20-inch alloy wheels, a 12-speaker Harman/Kardon sound system, leather upholstery, a panoramic glass roof, a BMW M body kit and more.

The most affordable iX2 is the eDrive20 that kicks off at $82,900, while the iX2 xDrive30 dual-motor all-wheel-drive is $85,700. Both of these currently fall under the luxury car tax threshold at the time of writing.

There are several individual options and options packages across the range that can quickly push these prices up. 

The X2 is a bit more expensive than the equivalent grades of the X1. The X2 xDrive20i costs $5500 more than the same X1 grade, while the M35i is only $2000 dearer than the equivalent X1. 

For the EV, the X2 price premium is $4000 for the eDrive20 and just $800 for the xDrive30.

When it comes to rivals, pricing is a little higher than similar swoopy small SUVs like the Audi Q3 Sportback when it comes to the petrol models.

For the EV, competitors include the Lexus UX300e ($79,990-$87,665), Mercedes-Benz EQA (from $82,300-$102,579), and the Volvo C40 Recharge ($78,990-$87,990).

Powering this GT-Line variant is a plug-in hybrid system that pairs a 1.6-litre turbocharged four-cylinder petrol engine with a small electric motor and battery. Combined, the system delivers up to 195kW of power and 350Nm of torque, which is plenty to get this sizeable SUV moving with confidence.

It’s a part-time all-wheel-drive set-up with a lock mode for extra traction when needed, and it’s paired with a smooth-shifting six-speed automatic transmission.

Around town and on the highway, the power delivery feels seamless and refined, with the electric motor doing a nice job of smoothing out stop-start driving.

One key trade-off, however, is towing capacity. While the diesel Sorento can tow up to 2000kg braked, the PHEV’s figure drops to just 1010kg. That’s a significant reduction and could be a deal-breaker for families who regularly tow a camper, trailer or boat.

Each of the four grades come with a different powertrain, and the xDrive20i kicks it all off with its 2.0-litre four-cylinder turbocharged petrol unit, making 150kW of power and 300Nm of torque. It drives all four wheels via a seven-speed dual-clutch transmission and can hit 100km/h in 7.4 seconds.

The xDrive M35i ups the fun factor with a gruntier 2.0-litre four-cylinder turbo-petrol unit, driving all four wheels via the same transmission as the 20i, all while delivering power and torque of 233kW/400Nm This ensures a 0-100km/h dash of 5.4 seconds.

The iX2 eDrive20 is powered by a 150kW/247Nm electric motor on its front axle, and the iX2 xDrive 30 uses two motors - one on the front and one on the rear axle for all-wheel-drive traction. The total system output is 230kW and 494Nm and the xDrive30 gets to 100km/h in just 5.6 seconds.

The Sorento GT-Line PHEV offers a WLTP-rated electric-only driving range of up to 57km - not huge, but enough to cover most daily commutes or school runs without dipping into the petrol tank.

When driven as intended and regularly charged, it’s capable of a combined fuel consumption figure as low as 1.6L/100km and this is paired with a 67-litre fuel tank. That means you could go a seriously long time between fill-ups if you’re topping up the battery daily.

In my week of testing, which included a mix of highway stints and urban errands, the trip computer reported an average of 7.2L/100km.

That’s well above the official figure, but still pretty reasonable considering the type of driving I was doing.

Charging is simple enough. The Sorento uses a Type 2 charging port, and on a standard 3.3kW AC charger, the 14kWh battery can be charged from 15 to 95 per cent in about three hours and 26 minutes.

Kia includes a portable AC charger with this grade, which is a handy bonus for charging at home or on the go.

A fuel-use figure for the xDrive20i is yet to be confirmed, but the front-wheel-drive sDrive20i offered in Europe with a three-cylinder engine sips as little as six litres per 100 kilometres on the combined cycle. Expect the Australian version to be a little higher than that given it’s AWD and has a more potent engine.

The M35i consumes 7.7L/100km. 

The high-voltage 64.8kWh lithium-ion battery in the iX2 ensures a driving range on the WLTP cycle of between up to 477 kilometres in the eDrive20 and between 417 and 449km for the xDrive30. 

The latter has an energy efficiency range of 16.3 to 17.7kWh/100km, and BMW says you should be able to top up the battery from 10 to 80 per cent in 29 minutes at a fast charging station.

That driving range is not bad compared with the Lexus UX300e and Peugeot e-2008, but not quite as impressive as the Volvo C40 twin-motor. 

I missed out on checking the energy efficiency figure of the iX2 xDrive30 following our drive, but after an 88km drive loop, the iX2’s range had dropped by 91km, which is just a 3km difference.

The Sorento PHEV hits most of the right notes when it comes to power delivery and gear shifts. Occasionally, there's a slight hesitation between whether the engine or electric motor should take the lead - like a dance partner who’s just a touch out of step. It’s noticeable, but not disruptive.

Most of the time, the transition between power sources is smooth, and there’s more than enough grunt for overtaking or merging confidently.

The suspension has a springy, soft edge to it and you’ll feel some movement over bumps but it’s never harsh or uncomfortable. It corners surprisingly well for a large SUV, with responsive, albeit lighter, steering. Body roll is present if you push into tight bends, but that's par for the course in a seven-seater.

Regenerative braking is subtle, almost too subtle. There’s not much feedback, and it can feel a bit heavy underfoot in stop-start traffic. It’s not a deal-breaker, but worth noting if you’re expecting the more pronounced regen feel you get in some other hybrids or EVs.

The cabin remains quiet at both urban and highway speeds, making it easy to hold a conversation across all three rows. Visibility is generally good, though the thicker pillars take a little getting used to. The digital rearview mirror is a great touch when the back seats are loaded with people or gear.

Parking is refreshingly simple thanks to a crisp 360-degree camera and front and rear sensors. One of my favourite features is the remote smart parking, which lets you move the car forwards or backwards via the keyfob, a lifesaver in tight parking spots. Just don’t teach your eight-year-old how to use it ...

The M135i xDriveis undeniably quick off the mark. The lovely 2.0L turbo engine is well matched to the seven-speed dual-clutch and it’s responsive and willing from a standing start and when overtaking.

The engine sounds lovely too, although we suspect it’s amplified in the cabin, and steering is as sharp as it should be in a warmed-up performance SUV. We darted through some very twisty roads outside Lisbon and had quite a lot of fun in the process, so the M Performance badge is justified. 

I drove the previous-generation X2 M35i a few years back and was disappointed with the ride quality. It was quite jiggly on uneven road surfaces and way too firm.

While the new version still has a firm tune to aid dynamic driving, it is much more compliant than the old car and overall ride comfort has improved.

The iX2 is also quick off the mark and in xDrive30 guise is only 0.2sec slower to 100km/h than the M35i. 

That lively, smooth EV acceleration is present here, adding a sense of fun to the iX2.

It too has sharp steering, and the cabin is hushed. Not just because it’s an EV either. We were on coastal roads on a windy day and there was only a hint of wind noise in the cabin.

In some instances taking corners that had typical European walls or houses right up against the road, the iX2 would slow before I had a chance to tap the brakes. But it was hard to tell if that was a vehicle safety function, or the regenerative braking.

The ride in the iX2 was a bit of a mixed bag. It coped with some of the pockmarked roads exceptionally well, soaking up the imperfections. But then on other roads it was a little choppy.

It also bounces a little when you go over speed bumps, but that’s not exclusively an iX2 trait. I’ve felt it on many an EV, given the placement of the very heavy battery packs under the floor.

On the driving tech front, the X2 has a well executed head-up display projected directly onto the windscreen. It includes the speedo of course, nav guidance, a crystal clear display and more info. 

The X2 and iX2 are yet to be crash tested by ANCAP or Euro NCAP for that matter.

As mentioned, it gets a more generous list of standard safety features than its predecessor. Features include the latest version of BMW’s front collision warning system, auto emergency braking, speed limit detection, active pedestrian protection and a front centre airbag.

All X2s come standard with BMW’s Driving Assistant Professional which features ‘Steering and Lane Control System’, adaptive cruise control with stop and go braking function, and a blind-spot monitor, as well as Parking Assistant Plus with a surround-view camera, reversing assistant and ‘Drive Recorder’.

The Sorento is backed by Kia’s seven-year/unlimited-kilometre warranty, which keeps the Sorento competitive in a market that is slowly starting to offer seven/year plus terms as standard.

You’ll also benefit from capped-price servicing for up to seven years or 70,000km, with an average cost of $764 per visit. That’s on the pricier side, especially when compared to some rivals.

Service intervals are every 12 months or 10,000km, whichever comes first, so if you’re someone who racks up the kilometres quickly, that could mean more frequent trips to the service centre than you’d like.

It’s also worth noting that the GT-Line PHEV requires a minimum of 95 RON premium unleaded petrol, which is something to factor into your ongoing running costs, particularly if you're already trying to offset fuel usage with regular charging.

The X2 range is covered by BMW’s five-year, unlimited kilometre warranty - something the German giant only increased from three years back in 2022. This is now the minimum standard.

The battery warranty for the iX2 is eight years or 160,000 kilometres. 

BMW does not have scheduled servicing terms, instead, servicing is condition-based and the car’s computer will alert the driver when to book in for a service.

A five-year servicing package will cost you $3171 for the petrol X2s, while the iX2 is $2186 for six years.
