BMW X2 vs BYD Sealion 8

What's the difference?

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.

There’s quite a bit to like here. There’s plenty of equipment, and lots of choice in price, trim level and mechanical complexity.

The driving dynamics are fine if you’re not looking for anything sporty although the performance offered by the dual-motor variants must be considered excessive, even if it’s pretty exciting the first time.

Perhaps what’s missing from the Sealion 8 experience is anything that stamps the car as something special within its hotly-contested market segment. Which is another way of saying it offers up the same limitations, most notably in the third row accommodation and access.

You only need to drive a one-box people mover and utilise the rearmost seat, to understand that the two-box SUV, while a pretty marketable thing, is compromised once the passenger count exceeds five. Nothing new there, but nothing new in the BYD, either, to change that narrative.

At which point, the front-wheel drive variant emerges as the most pragmatic choice and probably the one that meets all the important family tasks headed its way for the smallest outlay.

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.

BYD has done its best to give the Sealion 8 its own character and vibe. In fact, it’s a pretty smart looking thing - although still very much a two-box wagon concept - and that’s no given when you consider how much some big SUVs can start to look like large blobs of nothing when you look closely.

There’s the usual Darth Vader stuff at the front, but in profile, the diagonal vent across the front door makes a bit of a statement. The 'plaited' motif of the tail-lights might be stretching things a bit, though.

Inside, the modern board-room feel is invoked by the angular lines and high-tech look and feel of the large info-screens. The panoramic sunroof of the Premium grade also helps brighten up an otherwise pretty dark space.

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).

BYD has made sure all three rows of the Sealion 8 are fit for purpose while attempting to make the rearmost row (traditionally the trickiest to get right) less of a downmarket place to be. With that in mind, both rear rows get air vents and climate-control adjustment for that part of the car. There's also a pair of USB-C charge ports in the second row and a single USB-C and USB-A port in the third row. The third row also has cupholders bult into the wheel arch on each side.

With the third row in place, there’s a decent amount of luggage space (270 litres) largely thanks to the Sealion’s five-metre overall length. There’s no spare tyre, but a puncture repair kit lives under the floor (as does the removable cargo blind) and the rearmost luggage space also incorporates a 12-volt socket and luggage hooks.

A pair of pull-tabs drop the headrests and then the entire split third row in a single movement, at which point you suddenly have a five-seater with a huge, 960 litres of luggage space. And if you need to cart gear over people, the second row also folds flat to open up 1960 litres of space.

Up front, the feeling of spaciousness is amplified due to the low scuttle height and what the aviation industry calls the glass cockpit (no analogue dials or gauges at all). The 15.6-inch central info-screen runs the usual apps and control displays but, thankfully, the climate control touch-controls are tethered to the bottom of the screen, so they’re always visible regardless of what else is going on.

The 10.2-inch driver’s display adds a head-up function in Premium trim and displays the usual array of information required to operate the vehicle. But even better is the steering wheel which features a thick, well-padded rim that looks and feels pretty luxe. It also houses the usual buttons for stereo, phone and cruise-control functions.

A really nice touch is the addition of an extra set of tilt controls on the inside of the passenger’s front seat, allowing the driver to control that seat to allow people in or out without leaving their own seat. Nice one.

It is, of course, the centre row of seats that will make or break a car like this for many families. Even though many clans will not use the rearmost seat much of the time, the central row will get a huge workout. So it’s nice to see that leg, foot and headroom are all sufficient for even growing teenagers. Again, the car’s overall length appears to be the key, but it’s also worth noting the centre row seat is comfy and supportive. The outboard positions in the second row also feature heating and ventilation functions.

The third row, however, follows SUV tradition by being strictly for smaller kids. Access past those huge wheel arches is tight, and once you’re in, there’s a combination of dark trim and tiny windows to limit joy.

While it won’t matter to many buyers, the front-drive Sealion 8 is rated to tow 1800kg with a braked trailer, and up to two tonnes in the all-wheel drive version. But there’s no spare tyre fitted, and roadside flats need to be addressed by the included tyre repair kit.

BYD will offer the Sealion 8 in three trim levels, starting with the front-drive Dynamic at $56,990, before on-road costs, then moving to a pair of all-wheel-drive variants, the first with the same Dynamic trim level at $63,990 and the range-topping Premium AWD at $70,990.

The Dynamic trim level on both the front-wheel drive and the all-wheel drive variant gets you three-zone climate-control, air vents in both rear rows, full connectivity including wireless Apple CarPlay and Android Auto. There’s also wireless phone charging. The Dynamic specification also takes on 20-inch alloy wheels and there’s full LED lighting as standard.

Pony up for the Premium trim and you make the switch to 21-inch alloys, a 21-speaker sound system and even a massage function for the first two rows of seats. The Premium also includes a head-up display for the driver.

Not as easy to quantify is the level of plush inside the cabin. There are lots of soft-touch surfaces and the whole interior design looks pretty fresh and modern and well put together. But more than that, there’s a bit of design flair that makes the BYD feel perhaps a bit more expensive than it really is. That’s not an easy thing to pull off. But it seems to work here, even in the entry-level Dynamic trim.

Against the competition, the Sealion 8 can't match the similarly specified Chery Tiggo 8 on price, even though on performance and EV range, the Tiggo 8 and the entry-level Sealion 8 are quite similar. The more expensive Sealion 8 Premium, meanwhile, lines up pretty neatly on price with the Kia Sorento S PHEV. But that vehicle can't get close to the epic straight-line performance of the BYD.

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.

BYD has managed to keep a lid on the price of the entry-level version of the Sealion 8, by specifying it with front-wheel drive rather than the all-wheel drive of the other two variants. It still gets the same driveline beyond the lack of a driven rear axle, although battery capacity is the other difference.

As such, you’re looking at a 1.5-litre petrol engine (kind of the default powerplant for Chinese SUVs right now) with a turbocharger. With the 19kWh battery chiming in to power the electric motor, the driveline can achieve outputs of 205kW and 315Nm.

In the case of the AWD variants, the larger 35.6kWh battery and extra electric motor ups the potential outputs to 359kW and 675Nm which is a huge jump any way you look at it and gives the Sealion 8 a huge bandwidth when it comes to matching buyer performance aspirations.

All the variants have the potential for a claimed electric-only range of greater than 100km if owners use the plug-in facility to charge either at home or at work. For the AWD variants, the larger battery stretches the EV range to a claimed 152km. On longer journeys or whenever the battery has reached about 25 per cent capacity, the Sealion 8 acts just as any other hybrid with regenerative braking and electric assistance to aid performance.

In suspension terms, the BYD is pretty conventional but if you do pay the extra for the Premium variant, you’ll gain adaptive dampers.

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.

BYD claims a range of more than 1000km for both variants of the Sealion 8, provided you start with a fully charged battery and a full 60-litre fuel tank.

The BYD can also make use of commercial fast-chargers and, when using the maximum 40kW on the FWD version and the 74kW possible for the AWD variant, the charging times from 30 to 80 per cent are both under 20 minutes. The Sealion 8 can also charge at 11kW on an AC socket and the vehicle also offers V2L (Vehicle to Load) capability, meaning it can power on-site work tools, camping gear or even your house at night.

Provided the EV battery is kept at 25 per cent capacity or above, BYD claims a 1.0-litre per 100km fuel consumption figure for the car based on the laboratory test. In the real world, the results will vary enormously depending on where you drive and how the car is used. Deplete the battery and continue to drive at highway speeds, and your actual fuel consumption might easily increase to many times that 1.0-litre claimed figure.

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 first thing you’re going to do in a Sealion 8 is wonder where the gearshift is. It’s a column-shift, but it's not only located where a traditional indicator stalk would be, it looks very much like one, too.

This promises two things. One, you’ll spend a few seconds finding it and two, you’ll try to turn the indicators on with it at least once every drive. (The real indicators are on the other side of the steering column.)

Another note to those test driving a Sealion 8. Sample the front-drive version first. (I’ll get to why in a minute.) When you do, you’ll soon figure out this is a driveline that prioritises electric running. That is, the petrol motor barely ever actually drives the wheels (only at full throttle and higher speeds). Any other time, if the petrol engine is running, it’s to charge the battery that keeps the electric motor purring away. This is how efficiency is defined by BYD.

You’ll also find that the Sealion’s acceleration is purposeful in that electric-motor way, but hardly startling. And when you do smash the throttle and force the petrol engine to drive the axle, you’ll notice that this takes a fair time to play out, and that when everything is grunting as hard as possible, the petrol engine is quite noisy and even a little harsh sounding. Use the driveline sensibly, though, and it’s all smooth and quiet, even if that then means you can hear a little suspension noise creeping into the cabin.

That done, you’re now free to drive the AWD variant. Why wait? Because this thing is seriously off the leash. Bear in mind that 359kW of power is getting on for the thick end of 500 horsepower in the old money, so even though the Sealion 8 is a hefty critter at about 2.5 tonnes, all that power and torque will get it from rest in under five seconds, or thereabouts. The relevance of this to family-car technology is hugely debatable, but it’s one heck of a party trick the first time you try it.

The huge torque also magnifies the Sealion 8’s natural tendency to lift its inside front wheel when accelerating out of a turn. A small tyre squeak can sometimes be heard before the traction control gathers it all together, but even the single-motor variant displays the same trait.

In steering and suspension terms, it’s probably fair to say the Sealion 8 doesn’t unlock any new depths of talent. The ride is pretty comfy but at the expense of body control and the steering points the wheels but doesn’t convey much else to the driver.

That said, the fact everything seems to be tuned to the same frequency means it all works okay. You don’t have too-fast steering fighting the tyres or too firm suspension upsetting the interior calm. Use it as a family would, and it’s 100 per cent fit for purpose.

Any family car needs to be safe, so BYD has thrown the kitchen sink at the Sealion 8 in terms of its active and passive safety gear. That starts with nine air-bags including full-length curtain side bags and a centre-front airbag to help prevent head clashes.

There’s also a 360-degree camera on all grades, front and rear parking sensors, and the full line-up of current driver-assistance functions including autonomous emergency braking, lane-keeping assistant, rear-cross-traffic alert and assistance, blind-spot monitoring, driver attention monitoring and a tyre-pressure monitoring system.

To that lot, you can add adaptive cruise-control, traffic-sign recognition, adaptive headlights, front and rear collision warning, anti roll-over systems and hill-hold functions. It’s also worth mentioning that the overhead camera system is very, very good with a clear, crisp display and no processing delay.

The driver-attention monitoring seems to behave itself better than some of the over-active systems other makers specify, but the lane-keeping assistance function is still far form perfect. To be fair, it is less aggressive than some such systems and the intervention is more subtle, but the recued aggression seems to be packaged with lower sensitivity. As in, the cameras seem to sometimes miss a critical white line, particularly if its faded or less than freshly painted.

There are also ISOFIX child restraint tether points in both the second and third rows, as well as seat-belt warnings for every position and an electronic child-safety switch for the doors.

The Sealion 8 is yet to be crash tested locally, so no ANCAP star rating is available.

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.

Servicing any hybrid can be a bit more expensive thanks to the presence of two propulsion forms.

In any case, the Sealion 8 requires routine servicing every 12 months or 20,000km.

Warranty is BYD’s normal six-year/150,000km cover, although there’s also eight years and 160,000km of cover for the EV battery.

BYD also claims its 'Blade' battery technology is among the safest in the business, and says the design resists damage (and, therefore, the risk of fire) better than the competition.
