BYD Sealion 5 vs Polestar 4

What's the difference?

Cars that don’t always appeal to enthusiast buyers are often seen by manufacturers as a way of not bothering with the dynamics. Good enough is, apparently, good enough. Thankfully, BYD hasn’t taken that path here and the local suspension tweaks have turned what could have been a me-too product into a bit of a dynamic class leader. And even if buyers can’t verbalise the benefits of that, they will still be subliminally enjoying them with every kilometre.

The other stand-out feature is the price-tag which represents an awful lot of car for the money. And, in such a price-sensitive market as this one, that will get the BYD over the line for a lot of families. That it also offers a vastly better driving experience simply makes the value equation – and the purchasing proposition – even stronger.

Polestar may be a Tesla rival but the Polestar 4 looks and feels much more premium than the Model Y. The brand has taken its time to get the cabin just right and the sustainable materials don’t feel cheap in any way. In fact, this car feels special.

I may not be a fan of some of the tech - the digital rear-view mirror, for example - but many people will be drawn to the car because of these features.

On the road, the Polestar 4 is a cracking EV, with excellent driving range and a fun factor that can’t be denied. That aftersales offer is just the cherry on the cake.

This is Polestar’s best chance yet of being accepted by the masses.

The interior of the Sealion 5 feels pretty well-made and there are soft-touch surfaces on most of the touch-points. The steering wheel, too, is thick and chunky and nice to hang on to. But there’s a lot going on in terms of different colours, textures and surfaces, and it can all look a bit busy, despite the high-tech boardroom overall flavour. It’s also worth mentioning the trim material is synthetic but does a great job of looking and feeling like real leather.

Externally, there’s not a lot to grab the eye. Sure, it’s not an unpleasant looking vehicle, but neither does it stand out from the mid-size SUV pack. At least BYD decided against those cheap-looking plastic tack-ons on each wheel-arch.

Polestar pitches itself as a design-led brand and so far that checks out. The Polestar 2 is a striking sedan, the 3 is a bold, boxy, big SUV and now the 4 is the latest sexy addition to the range.

As mentioned, it is technically a medium SUV but it has a distinct fastback look. Polestar calls it a coupe-SUV. Whatever it is, it looks smashing in the metal.

The sleek silhouette pairs nicely with the split LED headlights and low-set front end. While there is an elevated ride height, it manages to sit low enough to the ground to look sporty.

The most interesting angle of the Polestar 4 is the rear. This car does not have a rear windscreen. The tailgate is made up of aluminium panels instead of glass, but the massive panoramic roof stretches back to the top of the tailgate.

The squared-off rear sits up high and houses gorgeous tail-lights that span the width of the car. Even though the rear is controversial given the lack of window, it’s probably the Polestar’s best angle. It’s unique and striking.

The Polestar 4’s interior design is best described as stylish minimalism. It is much more interesting than Tesla’s appliance-like cabin design, and it’s clear a lot of thought has gone into the interior. There are virtually no buttons which helps the look, but that can impact practicality. 

The integrated air vents look stunning as does the flat-bottom steering wheel.

A mix of whites, and light and dark grey materials are broken up by pops of colour like gold seatbelts. 

Recycled material is found throughout including the floor mats, dash toppers and seat upholstery, some of which is inspired by the fashion and sportswear industries. But being Polestar, it’s with a sustainable twist.

Here’s the other big shock relative to the price-tag of the Sealion 5: This is not a small car. Based on the price, you might have been thinking the vehicle would be a compact SUV. And you’d have been wrong. This is a proper mid-sized SUV with room for five and luggage and an overall length of 4.7 metres and change. And to put that into some kind of perspective, that’s just 30mm shorter than the Sealion 6 which costs about $9000 more at its starting point.

The wheelbase is long, too, and the 2712mm between the axles helps make the interior even more spacious. That means there’s lots of stretching room in the front, but also that a grown adult can comfortably sit in the back seat behind another grown adult at the wheel and still have enough room in every direction. The window sills are commendably low in the rear seat, too, ensuring even littlies can see out.

The biggest problem in the back is that the seat cushion is a bit flat, but, like the front chairs, it’s still pretty plush.

With all five seats in place, the Sealion 5 boasts 463 litres of luggage space and the cargo area is well done with storage pockets at each side, a light and an under-floor tray designed to transport charging cables and a tyre repair kit. Yep, that’s right, there’s no spare tyre of any sort here. No surprise, really.

Fold the rear seat down and you’re suddenly looking at 1410 litres of cargo space and your SUV is now a panel van.

As well as the dual-zone climate control, the Sealion 5 also offers a single USB -C and a USB-A charging port in the front and rear compartments.

The Sealion 5 also offers a V2L (Vehicle to Load) function, meaning it can power camping or on-site work equipment and even act as your home’s battery.

Sliding into the driver’s seat, the first thing I notice is how high the centre console sits. This is clearly a Polestar thing because it’s similar to the 2. This adds to the sporty feel of the cabin, but I don’t know if it needs to be that high.

It does however liberate a massive amount of storage space under the console. You could fit a handbag, shoes or other items there, and Polestar offers accessories like bicycle-esque bottle holders. 

There’s more storage in the smallish central bin which also houses two USB-C ports, a half-hidden phone charging pad, and door bins that will fit a larger bottle, but only lying down.

The seats are comfortable and the cloth-like sustainable material in the Singe Motor grade looks great, but it can grip on to clothes a little. The perforated Zinc-coloured ‘animal welfare’ Nappa leather in the Dual Motor is stunning and probably what I would opt for. Which is rare given I am no leather fan. But whatever the material, there’s a decent amount of support on offer. 

If you opt for the Nappa upgrade ($7000) you get Harman Kardon speakers embedded in the front headrests. It’s an interesting addition but it sounds quite cool when you realise where the sound is coming from.

Aside from the ‘play’ dial on the console, there are very few visible buttons. Meaning every function is housed in the central 15.4-inch landscape digital display.

I recently spent some time in another new Geely Group product - the Volvo EX30 - which has a similar set-up.

Thankfully, the menu is easy to navigate and the main screen is split between nav (running Google Maps of course) and up to four other functions, including apps like Spotify, a quick link to often-used controls and whatever else you want to customise.

Aside from the visually appealing graphics and colours, the display is crisp and easy to get your head around. The air con is easy to access and you use the screen to change the direction of the vents, which oscillate on the passenger side. 

The ambient lighting which is solar system themed is pretty cool, too. You pick the colour by planet. And the ‘Hey Google’ command appears to work well.

However, functions like opening the glove box should still be a physical button. There is no reason it needs to be housed in the screen. Also, adjusting the exterior mirrors and steering wheel required a lesson from the Polestar team. You can do it via the screen, or by using the smart controls on the steering wheel that change depending on what function you need. 

Again, this is very clever tech, but is it that necessary? Just because Tesla does something, doesn’t mean every other EV brand on the planet needs to follow suit. 

Then we get to the digital interior rearview mirror. While the lack of a rear windscreen does not impact the look of the car negatively, it’s another element that feels like tech for tech’s sake. Is there really enough of a benefit to interior space to justify this radical change to the car?

The display is clear but when you look at it then the exterior mirrors, the object in the display seems closer than the mirrors. There’s also no washer for the camera, with Polestar suggesting the angle means it doesn’t need one. The question remains, what happens if it malfunctions? 

I realise you can’t see out the back of plenty of vehicles, like trucks and, often, delivery vans. It’s also something you have to navigate when you pack your car full of gear for holiday and can’t see past all the luggage. And I appreciate many more people will be drawn in by the tech of it all. But for me it remains the answer to a question no one asked.

Moving to the rear, the slightly bucketed seats are plush and supportive and there is acres of legroom thanks to the Polestar 4’s 4.8-metre wheelbase. It is a spacious cabin no doubt, but the placement of the battery pack under the floor means your knees sit up higher than they would in an ICE car. It’s a similar phenomenon in Tesla models. There’s also no toe room under the front seats. 

You can, however, recline the rear seats slightly, making for a more relaxed vibe back there. There are amenities like rear digital climate controls, more USB-C ports, chest and knee-level air vents, and a fold-down arm-rest with cupholders, but big bottles won’t fit in the doors.

The boot appears shallow but there is under-floor storage where you can house the charging cable as well as flatter items. All up you get up to 526 litres of cargo space (that includes 31L under-floor), increasing to 1536L with the 60/40 split rear seats folded, while a front cargo space swallows 15L.

Polestar only offers a tyre repair kit for the 4, so no temporary spare. 

Polestar announced prices at the start of the year but the company lowered pricing by between $3000 and $4700 per grade ahead of the vehicle's arrival on Australian shores. That was enough of a drop to ensure it slides in under the Luxury Car Tax threshold.

Two grades are on offer initially, including the Long Range Single Motor real-wheel drive at $78,500, before on-road costs, and the Long Range Dual Motor all-wheel drive from $88,350.

Tesla’s Model Y starts at around $56,000 and tops out at about $83,000 for the Performance, so pricing for the Polestar 4 is aligned with something more premium. 

Other similarly positioned EVs include the Hyundai Ioniq 5 ($69,800-$91,300), Kia EV6 ($72,590-$99,590), Skoda Enyaq ($69,990-$83,990) and the Subaru Solterra ($69,990-$76,990).

In a smart move, both grades come with an identical standard features list. The key difference is the powertrain.

The healthy standard equipment list includes the Android Automotive operating system, 'Google Built-in', wireless Apple CarPlay, eight-speaker audio, a 15.4-inch multimedia display, solar system-inspired ambient lighting, eight-way power driver’s seat and six-way powered passenger seat, 20-inch aero wheels and the camera-based interior mirror that replaces the rear windscreen - more on that later. 

They also come with rain-sensing wipers, a digital key, keyless entry and drive, wireless device charging, heated front seats, digital radio and a panoramic glass roof.

There are a number of option packs available for both grades that bundle in features. The $8000 'Plus Pack' has the most features including increased AC charging from 11kW to 22kW, heated steering wheel and rear seats and a lot more.

There’s also a 'Pro Pack' ($2500), a Nappa leather upgrade ($7000) and the 'Performance Pack' ($7200) but that’s only available for the Dual Motor. There are also a number of individual options. 

While the 4 comes with a decent level of kit, features like a head-up display are only available in the option packs. This and a few other items should be standard at this price.

Both variants of the Sealion 5 have the same driveline – mostly. They each use a 1.5-litre petrol engine teamed with a single electric motor, both driving the front wheels. Unlike the bigger Sealions, there’s no all-wheel drive version. Power peaks at 156kW and torque at 300Nm.

Why a non-turbocharged engine? BYD tells us the non-turbo engine helps keep cost out of the vehicle and, since the engine really only runs to power the electric motor and charge the batteries, it does so at a relatively constant engine speed, negating the need for a wide spread of petrol power.

The only major difference is that the Essential version has a 12.9kWh battery-pack, while the Premium gets a bigger, 18.3kWh pack for longer range, but precisely the same output and, therefore, performance.

A single-speed transmission is part of the BYD driveline package, also made possible by the fact that the vast majority of the driving of wheels is done by the electric motor.

The battery electric Polestar 4 comes with two powertrain options. 

As its name suggests, the Long Range Single Motor has one motor driving the rear wheels only, and it pumps out 200kW of power and 343Nm of torque. That’s enough to help propel the SUV from zero to 100km/h in 7.1 seconds, on the way to a 200km/h top speed. 

The Long Range Dual Motor has a second motor on the front axle for all-wheel-drive grip, and the power and torque is bumped to 400kW and 686Nm, respectively. You’ll get to 100km/h a lot quicker at 3.8 seconds, too.

The Premium’s bigger battery claims to up the official NEDC range from the Essential’s 71km to 100km. BYD reckons with the 52-litre fuel tank brimmed and the car operating at its claimed 1.2 litres per 100km efficiency, the range of either version is just on 1000km. In the real world, that’s likely to be closer to 800km (especially with some highway running thrown in) but it’s still one heck of a solution to range anxiety.

There’s no DC charging function for the Sealion 5, so forget about commercial fast chargers. But on a 3.3kW AC power outlet, the maker claims the Essential can reach full charge in under four hours, while the Premium’s bigger battery will take under six hours to fully charge. A Type 1 charge cable is included.

The Polestar 4 uses a 400-volt, 100kWh lithium-ion battery.

The Long Range Single Motor has a healthy EV driving range of up to 620km on the WLTP standard, and energy consumption ranges from 17.8 to 18.1 kilowatt hours per 100 kilometres.

Range in the Dual Motor drops to a still very useful 590km and efficiency sits between 18.7 and 21.7kWh/100km.

We were in and out of different grades at the launch so didn’t capture real-world efficiency but we will when we do a full review soon.

AC charging is at a rate of 11kW, but if you opt for the $8000 Plus Pack that increases to an impressive 22kW which ensures a zero to 100 per cent home charge (32-amp) in just five and a half hours.

DC charging capacity is up to 200kW and Polestar says you should be able to get from 10 to 80 per cent full in about 30 minutes. 

These add up to solid figures for the price and segment. 

It comes with a type 2 and CCS2 charge port and a home charging cable.

You don’t have to drive very far to realise that the local input into the Sealion 5’s suspension and steering have been worth the effort. BYD Australia has a local engineering team on call these days, and it shows here.

Actually, the steering is not the highlight; it has some weight but not a whole lot of feel, or, indeed, feedback for the driver. The ride and handling combination is what stars. Obviously well-damped, the suspension allows for a ride that is both complaint and quiet, without causing the car to wallow around like some jacked-up designs can with their higher centre of gravity.

In fact, the BYD is athletic to the point where keener drivers will find it an entertaining drive; hardly something that can be said for the majority of medium SUVs.

Performance is strong without being overwhelming and even though the Sealion 5 has that signature electric-drive feeling of effortlessness, the accelerator pedal has been calibrated to avoid the neck-snapping surge of grunt off the line. As such, it emerges with a fairly flat acceleration curve, and no hint that the petrol motor is cutting in or out.

Until, that is, you bury the throttle all the way at which point the petrol engine takes a few second to join in. And when it does, it’s pretty vocal – shrill, almost – as it catches up with the rest of the car and starts directly driving the wheels. To be fair, though, this is not going to be a common occurrence in everyday life thanks to the flexibility of the petrol-electric system for 99 per cent of circumstances.

On the move, the cabin is perhaps most notable for its soft, plush seats that are a nice change from the church pews of some manufacturers. And although the driving position is about right, taller drivers might prefer a steering column that extends out another few millimetres.

The driver display screen is another source of annoyance. It’s pretty small and contains lots and lots of information, to the point where the typeface is too small to be read on the run by anybody who relies on reading glasses.

Some EVs tend to blend into one another when it comes to the drive experience. Thankfully, that’s not the case with the Polestar 4, which is the fastest Polestar model to date.

I drove the Single Motor and Dual Motor with the Performance Pack back to back, and both hold appeal for different reasons. 

The Single Motor is the everyday Polestar 4 and it is the one I would choose. There is ample power and torque on offer and that 7.1-second 0-100km/h sprint time is nothing to be sniffed at.

Riding on the standard 20-inch aero wheels with a high sidewall, the Single Motor is composed with a comfortable ride quality. The drive from Adelaide via various winding and pockmarked roads to the Barossa Valley highlighted how well the Single Motor can handle these sorts of surfaces. It’s not as comfy as a Camry, but Polestar has ironed out most of the firmness.

Steering feels light but super sharp in the Single Motor and while there is a hint of body roll, it is still exceptionally capable on the twisty stuff. It also doesn’t feel anywhere near its 2230kg kerb weight.

The Dual Motor is a different beast, especially when paired with the Performance Pack. That pack adds, among other items, Brembo brake callipers and a ‘Polestar Engineered’ chassis tune.

It is brutally quick from a standing start. Like ‘pull your face back’ quick. Zero to 100km/h in 3.8sec to be precise. It’s a hoot, but it is much more than just a straight-line speed machine. 

The Dual Motor carves up corners, again with slight roll, but it has no business being this sharp given its dimensions and weight. We sprinted (safely) through bends better suited to a tiny performance hatch with ease. 

You can adjust the chassis to your preference. Suspension runs from 'Standard' to 'Nimble' and 'Firm', and steering is either Standard or Firm, the latter adding quite a bit of weight to the steering. Power delivery is either 'Range' or 'Performance'. Obviously, the latter is the most fun. 

Even in Standard suspension mode, the ride is much firmer than the Single Motor, which isn’t helped by the massive 22-inch wheels. It is, however, never unbearable. In fact, it’s more than fine on some of the average roads we encountered. 

The Polestar 4 is well insulated, ensuring a hushed cabin. 

The Polestar 4 is yet to be assessed by ANCAP or Euro NCAP so it’s unrated for now.

But it comes with an extensive list of standard safety gear, including the latest advanced driver assist systems. That’s one of the benefits of sitting under the Geely umbrella next to Volvo.

This includes adaptive cruise control, ‘Collision Avoidance and Mitigation’, ‘Run-off Road Mitigation’, forward collision warning, lane keeping aid, ‘Post Impact Braking’, road sign recognition and ‘Driver Alert Control’.

Other gear includes ‘Blind Spot Information System (BLIS) with steer assist’, a cross-traffic alert with brake support and a rear collision warning and mitigation.

The Polestar 4 is fitted with 11 exterior cameras, 12 ultrasonic sensors and one front radar to help keep you safe.

It also comes standard with the 'Pilot Pack' that includes lane change assist and pilot assist, which is semi autonomous driving.

Like other BYDs, the Sealion 5 comes with a six-year/150,000km warranty. Some of the competition have unlimited kilometre warranties, but to be honest, 150,000km in six years is going to be beyond the need and aspirations of most owners.

The EV battery is covered by an eight-year/160,000km warranty, and let’s not forget, BYD was a battery manufacturer before it started making whole cars. Certainly, the company is very bullish about the quality and safety of its 'Blade' battery technology, claiming it easily passes the technically-daunting 'nail-puncture' test.

BYD plans to have capped-price servicing for the Sealion 5, but no pricing announcements have been made yet.

Servicing also falls into line with other BYD models, so that means 12 months or 20,000km intervals.

Covering the Polestar 4 is a five-year, unlimited kilometre new-vehicle warranty, and an eight year, or 160,000km battery warranty. 

Complimentary roadside assist covers you for five years too.

The service schedule is every two years or 30,000km.

But the big news is that Polestar won’t charge you a cent for servicing for the first five years, or 100,000km of ownership, whichever comes first - it’s complementary.

This is an outstanding aftersales offer.
