BYD Sealion 6 vs Tesla Model Y

What's the difference?

So, should Toyota, Tesla, Hyundai and others be worried about the arrival of the Sealion 6 and BYD’s new DMi powertrains? Yes, but not because it represents any major breakthrough in technology or dynamic prowess. 

Instead, the strength of the Sealion 6 is how average it is. It may not be the obvious class-leader in any particular area, but it does a good job in almost every measurable aspect and doesn’t possess any major flaws.

Yes, there are still questions about the long-term dependability of BYDs but that’s a risk any new owner will need to accept. But the very sharp pricing should tempt plenty of buyers to take that chance and continue BYD’s steady upwards trajectory in the Australian market.

Completely putting aside the Elon Musk factor, there’s no question the Model Y was in need of an update to keep it fresh and attractive to buyers. On a purely automotive level, the changes they’ve made have been almost universally positive.

Tesla has had to adopt the traditional car company plan, which is out of character, but the new look and tweaks to the ride and specifications make it feel fresh, new and better - which is exactly what the brand needs to continue to grow its market and win back those who have started to look elsewhere.

Whether that’s enough in the face of both the Musk element, slowing EV market and increased rivals - especially those from China - remains to be seen. But if Tesla sales remain in decline, at least it won’t be for a lack of trying to make the Model Y better.

This is one area where BYD has a mixed record. Not to be unkind or create an international incident, but the Chinese car industry has a history of not being totally original with all of its automotive designs.

However, things are improving and the Sealion 6 is a good example of the Chinese industry learning to develop its own style. While there are some subtle hints from European models, overall it’s a smart-looking mid-size SUV with some character to it - rather than being a bland imitation of something else.

One area where the Sealion is a cut above its competition is its size, being longer than and wider than the RAV4, Mitsubishi Outlander and Nissan X-Trail.

Tesla’s original game plan was to focus on software updates to keep its cars fresh and appealing, rather than the traditional facelifts and specification tweaks that other car companies use. But, in what should probably not be a surprise, it turns out the rest of the car industry hasn’t been doing mid-cycle facelifts and updates for every other car for no reason - it did them because they worked.

To that end, this ‘new’ Model Y isn’t all-new, but rather the existing platform with refreshed styling. It takes Tesla’s latest design cues taken from the Cybertruck and Cybercab concept, with a new-look front end that is dominated by this LED lighting that runs across the entire width and wraps around the corners into the headlights.

There’s a new, flatter bumper, which takes styling inspiration from the Cybertruck but the company claims it’s also more aerodynamic. While at the rear there’s been an equally extensive redesign, with new lighting and tailgate. Tesla claims the new rear light bar that runs the width of the car is one of the longest of its kind in the industry.

I’ll leave it to each individual reader to decide whether they like the look of the 2025 Model Y, but objectively speaking it certainly looks different enough from its predecessor that it could entice existing owners to upgrade or attract new buyers.

Inside the changes are less noticeable, with some subtle but significant tweaks. Visually the biggest change is a new wrap-around ambient light strip that runs from door to door across the front of the dashboard.

But the rest of the layout is largely what was there before, with one notable exception. Tesla has taken its ‘minimalist’ design to the next level and removed the gear selector stalk on the right-hand side of the steering column. Instead you need to use the central touchscreen to get the Model Y moving.

To be candid, I don’t like this, it makes for a less convenient, less tactile and less initiative way to change gears, while also making the central screen even busier. Aesthetically, with the left-hand indicator stalk still there, it makes an asymmetrical design element in an otherwise symmetrical cabin. Which is where it starts to feel less like a design choice and more like a cost saving decision.

In fact, despite the good quality materials used throughout the cabin and good build quality, personally I find this almost-buttonless, so-called minimalist cabin just looks and feels cheap with so little in the way of details and design flourishes. Especially against the wave of incoming similar-sized and sometimes cheaper Chinese electric SUV rivals, that either look very similar (Deepal S07) or have similar technology and add some more design flair (BYD Sealion 7).

One design element of note is the lack of any Tesla badging on the front. There’s no ‘Tesla’ or even a ‘T’ badge, which is in keeping with the Cybertruck design but is another meaningful change from the previous Model Y.

That external size translates to a roomy cabin, which also has some flair to the design but thankfully a bit more restrained than the smaller Atto 3 - which is a bit over-the-top in this reviewer’s opinion. 

The element that sticks out immediately is the large central touchscreen which, like other models in the range, can rotate either vertical or horizontal, depending on your preference.

I don’t understand the point of this, because when rotated vertically it impacts your forward vision and can interfere with the air conditioning vents; and I can’t even see it with my polarised sunglasses.

It simply makes more sense horizontally, but I guess all carmakers are looking for catchy gimmicks these days. But while it may seem like a cool party trick it remains somewhat confusing to me, like one more thing to go wrong. But maybe I’m just getting old and grumpy.

What I do like and think is a great idea is double smartphone charging pads in the centre console. And overall the design of the cabin feels well thought out and has plenty of useful storage areas.

The seats are fine, a little flat and the fixed headrests are irritating, but overall they’re soft and supportive enough.

The key in the second row seating is the amount of space, with the extra length of the Sealion 6 compared to its rivals showing up with more knee room in the back for families with growing teenagers or those who need to carry their adult friends.

There’s also a pair of USB ports in the back too, so everyone can keep their electronics charged.

The boot is a good size, measuring 425 litres on paper, and has a nice long and wide floor. But some of that space is thanks to the lack of a spare - so that counts against it in my book.

From a space perspective, the Model Y offers good room front and rear for an SUV of this size. The addition of the rear heated seats and small touchscreen that can support two Bluetooth headphones is very nice. 

There’s plenty of small item storage thanks to a large centre console between the front seats, with space for two wireless smartphone charging pads, two cups or bottles and a pair of large lidded storage spaces (albeit with only a single USB-C input).

In terms of luggage space, the Model Y does a nice job, thanks to its 117L front boot (or frunk), while at the rear the boot has a claimed 854L of cargo space with underfloor storage. However, that big boot comes at the expense of any sort of spare tyre or even a puncture repair kit. Instead, Tesla offers roadside assistance and brings you a spare wheel and tyre or takes you to a tyre store. Which is fine if you have a flat in an urban area and a Tesla service vehicle can drop off a spare in short order, but if you’re in a regional spot you may be waiting a while for a job that some people can do in 15 minutes or less.

As for the in-car technology, there’s no question that Tesla has created a good infotainment system and it runs quickly on the big, hi-resolution screen. However, once again Tesla’s desire to be different and not conform to the industry norms rears its head.

There’s no Apple CarPlay or Android Auto compatibility, because Tesla wants to only run its system and not deal with third parties. And, yes, you can still pair your phone and get very similar functionality, but it is not the same functionality and seems like a compromise for customers.

The Model Y still has plenty of the ‘Easter eggs’ that are a much-talked about part of Tesla lore. And honestly, they’re fine, a nice little bonus, but the truth is, like so many other car ‘surprise and delight’ features, they don’t add any meaningful long-term value to the ownership or user experience. I used to get excited by them when I first drove Teslas, but within a few days you tend to forget about them.

On a positive note, the Tesla App is a great feature, allowing you to keep in contact with your car, and access cameras and other features remotely, while also using your phone as a key. Which is good, because otherwise you have to use a key card, which allows keyless entry but the card has to be pulled out of your pocket and placed on the wireless phone charging pads in order for the car to start, which just seems unnecessarily complex.

Of course, one of the most important elements for any car’s sales success is its price and the value it offers customers. That’s why this is one of the (non-political) automotive reasons behind Tesla’s sales decline. Put simply, the American brand has more rivals now, particularly those from China that are undercutting it.

The list of cheaper electric SUVs now includes the BYD Atto 3 and Sealion 7, Deepal S07, Kia EV3 and EV5, Geely EX5, Leapmotor C10, XPeng X6 and Zeekr X. With customers having more choice and overall demand for EVs starting to plateau, Tesla will need to fight harder for each and every sale.

Tesla repeatedly cut the cost of the old Model Y, reaching as low as $55,900, but this new version starts at $58,900 for the RWD variant and $68,900 for the Long Range AWD we drove.

Some of the key specification highlights for this updated Model Y include new heated and ventilated front seats, improved heated rear seats, an 8.0-inch infotainment screen in the rear, ambient lighting, acoustic glass, pixel-by-pixel headlights and a new hands-free tailgate that can open on approach.

The elephant in the room is re-sale value, with Tesla's repeated price cuts impacting the used car market and therefore the value it offers you. Tesla Australia has indicated that the multiple price cuts that impacted the previous model in its later years are a thing of the past, but a discount or sale is always a helpful way to drive sales in troubled times.

While BYD has made its name in Australia as an all-electric brand it has always referred to itself as a 'new energy' company, and the Sealion 6 (and upcoming Shark ute) are why.

That’s because these feature BYD’s new 'Dual-Mode Intelligence' (DMi) powetrain - a hybrid system to you and me.

As mentioned above, the biggest difference between the Dynamic and Premium models is the powertrain, with two reasonably different systems.

The Dynamic is powered by a 78kW/135Nm 1.5-litre four-cylinder petrol engine, paired with a 145kW/300Nm electric motor - making for a combined system output of 160kW/300Nm. Notably, this powertrain only drives the front wheels.

In contrast, the Premium has an all-wheel drive set-up, combining a turbocharged version of the petrol engine (good for 96kW/220Nm) with a pair of electric motors, one on the front axle and one on the rear to produce a combined output of 238kW and 550Nm.

Both models get the same 18.3kWh ‘Blade’ battery, which is BYD’s proprietary technology underpinning all of its models and is attracting attention from other brands.

For reference, the Outlander PHEV has a 20kWh battery, Nissan’s X-Trail e-Power has a 2.1kWh battery, while the more conventional RAV4 Hybrid has just a 6.5Ah battery.

For all the difficulties Tesla has been suffering lately, and amid all the new challengers, one area where the brand remains in a strong position is its powertrains and battery technology. It is still among the best in the business, and should be the reason you buy a Model Y more than its ‘Easter eggs’ or buttonless interior.

Tesla is notoriously cagey when it comes to its power and torque figures, but all indications are the motors haven’t been changed. That means the RWD makes 220kW/420Nm, while the Long Range we’re in has a theoretical 331kW/559Nm.

What Tesla has confirmed is the new Model Y is faster, thanks to a software update, with the RWD a full one second faster from 0-100km/h - now taking 5.9 seconds - and the Long Range is two-tenths quicker at 4.8 seconds.

There are multiple modes to drive it in, including electric only, with the Dynamic able to go up to 92km on a single charge, while the Premium manages a claimed 81km.

However, it's important to note these are the NEDC standards and not the more real-world like WLTP,  so you may not achieve those in practice.

The claimed fuel consumption is an impressive 1.1L/100km for the Dynamic and 1.4L/100km for the Premium although again achieving those in the real world will take some effort.

With a 60-litre fuel tank BYD claims the Dynamic has a driving range of just over 1000km, while the Premium can manage around 960km.

It's also worth noting the Sealion 6 comes equipped with vehicle-to-load charging which means you can draw power from the batteries to run small electronic devices if you need to.

It’s a bonus feature that may or may not be of use, but is one of those things that may come in handy one day to get you through a camping trip or a BBQ at the park.

While it may not be more powerful, Tesla has extended the range on both the RWD and Long Range.

The RWD has been stretched to 466km, an improvement of 11km, and the Long Range lives up to its name with a 551km range - an 18km increase over the old model.

In the real-world though, we noticed quite a dramatic decrease in battery percentage on relatively limited urban driving, so much so we’d need a longer evaluation period to confirm whether you could consistently get more than 500km from a single charge. Even working from home, and driving a second car during the week we had the Model Y, I was on course to have to recharge within a seven-day period.

When you do need to recharge, Tesla operates its own Supercharging network, so in addition to being able to use the growing number of public chargers, you can probably find one of Tesla’s 110 Superchargers near you.

Charging is nice and easy too. You can upload your credit card to the car so you only need to plug in and it will automatically start replenishing the batteries.

We drove the Sealion 6 Dynamic and despite having the less powerful powertrain it feels good on the road. The DMi system offers good performance, with quiet acceleration off the mark and a good integration between the petrol engine and electric motors. We haven’t driven the Premium yet, so we can’t make any comment on how different it feels.

It’s hard to make a definitive call on the Sealion PHEV powertrain because, like every plug-in hybrid, its greatest strength relies on how the owner operates it.

If you don’t charge the battery every day or so, you’ll just end up lugging around a battery and electric motor for little benefit. However, if you do keep the battery topped up, you can do most of your urban commuting without needing to turn the petrol engine on, which should result in some very low fuel consumption figures.

The company clearly knows this, which is why BYD Australia is offering a complimentary home charger to the first 3000 customers who order a Sealion 6.

Not only will that encourage sales but it will also help owners become evangelists for PHEVs in the future, because they’ll have the best possible experience.

So, a large part of its strength or weakness rests on the owner’s behaviour and that’s something we can’t assess.

As for the rest of the driving experience, the ride comfort is fine. It can’t match the class-leaders for compliance or dynamics, but the Sealion feels pleasant to drive around the urban environment and on the freeway at speed.

Biggest criticism is the steering is very, very light. While that makes parking easier, it feels so light you get very little feedback from the front wheels so it can feel vague at times.

Overall the driving experience is best described as fine. It doesn’t have any major vices but neither does it set any new benchmarks. 

One of the most significant mechanical changes for this new Model Y is retuned suspension. The previous Model Y was criticised for its uncomfortable ride, especially in the rears, and Tesla has acted to change that. 

The ride is more comfortable but still on the firm side as it needs to control the weight of all the batteries. Overall the changes have brought a positive impact and helped improve one of the weak points of the Model Y.

Tesla has also added lower rolling resistance tyres and acoustic glass, both of which help refinement and make for a quieter cabin. That was an early problem with the Model S, the amount of road noise and mechanical groans and squeaks that were audible without an engine to mask them. Tesla has worked hard over the years to make a much more refined and quieter electric vehicle.

From a driving perspective, the Model Y is nice without offering anything class-leading or particularly stand-out. Tesla claims the new tyres help improve handling, but there's no real evidence of that from behind the wheel.

In fact, the Model Y doesn't really have any element of the driving experience that stands out amongst its newer rivals. The motors offer good, effortless performance, but the driving character - the steering, the chassis handling - just lacks any above-average quality.

One area where Tesla has caught up to some of its EV rivals is adding a different level of regenrative braking, with a relaxed setting that allows for a more conventional two-pedal driving experience than the standard regen, which is quite strong.

Still, it's hard to give Tesla any more points for its Driving score because it simply feels very much average for the current class of EV SUVs.

Safety is another area where Tesla has some standout features. As this is an updated, rather than an all-new model, it has the same crash structure as the 2022 Model Y ANCAP tested and awarded five stars.

It gets all the basics you expect, such as seven airbags for full occupant protection, autonomous emergency braking (AEB), lane departure warning and so on. But there’s some extra elements worth mentioning.

And we need to start with Tesla’s much talked about ‘Autopilot’ - which isn’t the Full Self Driving System that’s offered in America. Instead, it’s a very fancy sounding name for the same sort of adaptive cruise control and lane keeping assist most brands offer. We had some significant issues with this system during our week of testing, with the car repeatedly slowing dramatically when the Autopilot was engaged, despite no obvious reason to do so.

Another issue with the Autopilot is the specific ‘Autosteer’ function, which is clearly listed as in ‘Beta’ form, which means it’s not in its final, production-ready form. I don’t believe customers should be beta testing anything for carmakers, either it’s ready for us to use or it isn’t. Tesla is the only car I’ve ever driven that openly admits it is offering a not-fully-tested system and it simply doesn’t make sense to me that they get away with it.

But, as is a theme here, for every questionable Tesla element there is a counter element that’s positive. In terms of safety it’s the Sentry Mode, which is a great system that allows you to record movement near the car in case of threat of theft or damage by automatically turning on the external cameras if someone approaches the car. You can check in real-time from the Tesla app too, so it adds a layer of functionality and peace-of-mind that few others can match.

Similarly, another handy safety feature is the in-built dashcam, that uses the forward facing safety camera to record video. It can be programmed to activate on a specific command, such as beeping the horn, so you can capture any incident and get evidence to help with an insurance or dangerous driving incident.

BYD is a small company but has partnered with mycar service centres to make maintaining your Sealion 6 easier. The Sealion is covered by BYD's six-year/150,000km warranty as well as its 10-year capped price servicing plan.

Service intervals are every 12 months/20,000km and prices range from $265 up to $1184 for the major eight year/160,000km tune up. Over the first five years, in keeping with most of its rivals, you’ll be paying $1648.

As I’ve written in previous BYD reviews, the biggest question mark hanging over the brand is arguably its long-term prospects. Quite simply, the brand is still too new to know how well it will perform on the used car market.

We also can’t tell you how it will hold up from a reliability point-of-view. We’re not suggesting there’s any doubt over its quality, but each car brand must prove itself reliable and dependable over time, and BYD hasn’t had that time yet.

Tesla has a relatively short warranty for the Model Y, at least by modern standard, at just four years and 80,000km. However the battery and drive units are covered for eight years, so you do get more peace of mind that any battery issues will be resolved.

However, there are different mileages for the RWD and Long Range models, and Tesla says the batteries only need to retain 70 per cent of their performance to be within their limits.

Servicing is another non-traditional area for Tesla. The company doesn't offer fixed-service intervals, but rather the car will alert you when it needs a service. BMW and Mini also do this.

Naturally, there are less lubricants and other consumables to maintain as you’d find on a petrol-powered SUV, but there are still parts like brake fluids and air filters that need to be looked at by a technician.
