BYD Sealion 8 vs Polestar 3

What's the difference?

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.

With the kind of driving range, dynamics and comfort that could convince even the EV doubtful to give it a crack, the Polestar 3 – and specifically this Long Range Single Motor – feels like it was worth waiting for.

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.

I think the Polestar 3 looks great – big, but not looming, and still somehow svelte enough to look sporty.

The brand takes a unique approach to marrying design and aerodynamics, with a lip at the edge of the bonnet that allows for airflow. But it doesn't look like a purely functional element.

Instead it accentuates what Volvo would call the 'Thor's Hammer' (but I think Polestar calls them 'Twin Blade') headlights, which are mirrored below with black venting.

In fact, looking at the 3 front-on is a bit like looking into a reflection in a crystal-clear lake, with the lighting signature perfectly reflected in the lower half of the front end.

If it sounds like I'm waxing lyrical, it's because I am. I think the Polestar 3 is among the best looking vehicles in its segment and one of the better looking SUVs, period.

Inside, though, it's a study in minimalism, which while very neat and tidy, makes it feel a little less luxe than you might expect from a vehicle at this price point. In fact, at a quick glance, it doesn't look that far removed from the relatively cheap-as-chips MG4's cabin.

The materials are thoughtful and lovely, though. Leather-like materials are used sparingly, replaced by what Polestar calls "Bio-Attributed MicroTech Charcoal with Repurposed Aluminium Deco". A far easier way to describe it, though, would be as reminiscent of a wetsuit.

Elsewhere, it's a fairly pared-back affair, with just the huge portrait-style central screen and the landscape driver screen grabbing your attention. Dig deeper, and there are some really nice, gentle details, like the ambient interior lighting that illuminates a little strip along the door panel, including the Bowers & Wilkins logo. A similar line of light spans the entire dash, too.

And I love the metallic-look panel along the dash which, one can only assume, is the 'Repurposed Aluminium Deco'.

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.

Polestar has done a solid job of disguising the dimensions of the Polestar 3, because while it looks sleek and sporty it's still a big boat, stretching a sizeable 4900mm in length, 1968mm in width and 1618mm in height.

That size is most noticeable in the back seat, which is properly cavernous, helped further by a fully flat floor which lends even more airiness. Sitting behind my own 175cm driving position there's plenty of headroom and tons of knee room, giving the Polestar 3 official adult-friendly status.

The ISOFIX attachment points are located beneath two pop-off plastic covers, which makes fitting a child-seat base super easy. This is something I wouldn't have cared about at all exactly 22 weeks ago, but now I care a lot, and this was among the fastest and easiest systems I've used.

Happily, there is no major back seat compromise, either. The pews are comfortable and supportive, with the window seats separated by a pull-down divider home to two pop-out cupholders.

There are twin USB ports for rear-seat riders, too, as well as air vents with temperature controls, and – thanks to that Plus Pack – rear seat heating.

There's storage aplenty, too, with a total 597 litres in the boot with the rear seats in place, and 1411 litres with them folded flat, including a handy 90-litre hidden storage spot under the boot floor. Up front, there's a soft-bag-ready 32-litre frunk.

I'm going to get this out of the way early. I am a touch surprised with the pricing on the Polestar 3 range.

With Tesla having now stepped on a million metaphorical rakes, and with a leader now slightly less popular than actual skunk musk, the stage seemed set for a rival brand to steal its crown, and its customers.

But I can't see too many making the leap from the $60K-$70K Tesla Model Y to the $118,420 asking price of the admittedly bigger Polestar 3 Long Range Single Motor - which is the cheapest way into the brand's large SUV.

Instead, Polestar will be taking aim at brand's like BMW, Mercedes-Benz, Porsche and Cadillac, leaving its Chinese corporate cousins (think Zeekr and Geely) to chip away at Tesla's market share.

So, premium product, then. But do you get premium stuff?

Ours gets the 20-inch 'aero' alloys, but you can spec those up to 22-inch wheels if you don't like your spine very much, along with Brembo brakes. Plus there's is LED lighting all around, a big glass roof and retractable door handles.

Inside, the Long Range gets heated front seats, triple-zone climate control, wireless device charging, and a big 14.5-inch central screen with Apple CarPlay and Android Auto (run by Google built-in) joined by a second 9.0-inch driver information screen above the steering wheel.

Our car was also equipped with what Polestar calls the 'Plus Pack', a cool $9.0K on top, which adds things like a 25-speaker Bowers & Wilkins for Polestar stereo (replacing the standard 10-speaker set-up) , a head-up display, heating for the rear seats, steering wheel and wiper blades as well as soft-close doors.

The as-tested price for our car, by the way, is $131,640, before on-road costs.

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.

The  Long Range Single Motor tag hints at what's powering this Polestar 3, with a single, rear-axle mounted (so, rear-wheel drive) motor producing 220kW/490Nm and a fairly sedate sprint from zero to 100km/h of 7.8 seconds.

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.

How far is far enough before you'd consider an EV? Because I've got to say, if I owned the Polestar 3, I'd probably have to plug it in once a week, if that.

A sizeable 111kWh lithium-ion battery provides the charge here, and unlocks a claimed WLTP driving range of 706km. Now, it's worth pointing out these numbers are rarely realistic. For example, WLTP testing is conducted with the climate control switched off, but a real-world result of 600km or more, depending on how you drive, is still a large number.

The battery is the same as in the dual-motor variant, but this RWD car is lighter and less powerful, and it has a lower top speed (180km/h), reducing its energy usage to 17.6kWh-20.3kWh/100km (from 19.6-21.8kWh/100km).

The Polestar 3 has a 400V architecture, meaning hyper-fast charging speeds are out of the question. Instead, it's capped at a maximum 250kW (still more than most public chargers in Australia can produce) which means a 10-80 per cent charge in 30 minutes.

At home, an 11kW charger will take more like 11 hours, or an estimated 16 hours using a regular 7.0kW wallbox.

According to Canstar Blue, the average price per kW for residential power in NSW at the moment is about $0.34. So, using my admittedly questionable maths skills, it would cost around $37 to take your Polestar 3 from empty to full at home.

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.

The Polestar 3 is that rarest of beasts – a big and sumptuous SUV that's genuinely engaging to drive.

This is going to sound odd given we're talking about 2.5-tonnes of Swedish metal but I reckon the fact it's not lightning-fast makes it more fun to drive. It somehow (and yes, this is a crazy thing to say) gives off Mazda MX-5 vibes, in the sense that, while some EVs feel utterly scientific in the way they accumulate speed, this rear-drive Polestar feels fun, perky and like you're actually driving it.

Don't get me wrong, there's more than enough power on offer here to get the 3 up and moving, especially the way it accelerates from low to mid speeds, but it's more than powerful enough to feel like you can push it a little bit harder without risking a visit to the undertaker.

The ride is good, too, leaning into its sporty nature without vibrating your eyeballs through suspensions stiffness, and the steering is direct and predictable. Speaking of which, you can dial up the sportiness of the accelerator (responsiveness) and steering (weight), too.

I also like the three-stage brake regeneration (off, medium and full 'one-pedal' driving) accessed through a permanent button at the base of the screen, and I prefer that it isn't as brutal as it can be in other vehicles. The cabin is also impressively quiet, though how much of that is owing to the Plus Pack's upgraded stereo arriving with active noise cancellation is a mystery.

There is no shortage of weight on board, though, and get too aggressive with the steering wheel and you'll get that disconcerting top-heavy tipping feeling so common with big SUVs.

I'm not convinced by the Polestar 3's software, either, with a couple of weird warnings popping up during my time with the car. The first warned that the driver assistance systems had failed, and told me to book a service, and the second even weirder issue is it liked to warn me there was "no valid key detected" despite it being in the centre console, and that "restart would not be possible".

Neither warning seemed accurate, to be fair, as the safety one went away on its own after a while and I had no problem starting the car.

The Polestar 3's safety story is a good one, and it begins with nine airbags covering all seating rows. The grille of the 3 is home to what the brand calls its 'SmartZone', which is where it hides the cameras, sensors and radars necessary for its AEB (with cyclist and pedestrian detection), cross-traffic alert with braking, blind spot alert with steer assist, lane departure warning and assist and active cruise control. The list goes on and on.

In the cabin, two infrared cameras monitor the driver, while four motion-sensing radars scan the rest of the interior for left-behind pets or children.

It scored the full five stars in Euro NCAP testing, and scored the highest child occupant protection rating of any passenger car tested by Euro NCAP in nine 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.

Another tick for the Polestar here. While I advocate for longer warranties (kudos to brands like Nissan, MG and Mitsubishi), the 3's five-year, unlimited-kilometre warranty and eight-year, 160,000km battery warranty is on par with its premium competitors.

The first five years or 100,000km of servicing is on the house, too (it's required every two years or 30,000km after that) and five years' roadside assistance is thrown in, as well.
