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.

Tesla promised wholesale improvements to the Model Y, and this Juniper update delivers where it counts. But with increased, and sometimes cheaper, competition arriving every day, the pressure remains on Tesla to keep the Model Y ahead of the pack.

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.

We’re not talking massive changes here – more a modernising of the Model Y offering that doesn’t really change the shape or dimensions. 

The most noticeable changes outside are the front and rear light bars, spanning the width of both the bonnet and the boot. They’re a nice touch, and seriously soften what many (including me) consider the worst angles of the Model Y. There are also new headlights, a refreshed front bumper and a new look for the alloy wheels.

Inside, it is the absolute definition of pared-back minimalism. In fact, some could argue it’s gone a little bit too far.

There are no physical buttons anywhere but on the steering wheel, and there's just the one stalk, which has the sole function of operating the indicators. Everything else - mirrors, windscreen wipers, headlights etc - are accessed either through the steering wheel, or through the central screen.

And that includes the gear selector, which is now a swipe-down-for-reverse, swipe-up-for-drive function on the central screen. You might love that, but I don't. I'm sure I'd get more used to it, but initially it did nothing but slow down how quickly I could get the car moving.

Helpfully, the central screen is big and very easy use, and logging into Spotify and Apple CarPlay does largely negate the missing phone mirroring – though if the function exists, I couldn't get it to read my incoming texts to me.

Our test car's cabin was black but highlighted with quality-feeling fabric panels in the doors and on the dash, which are then framed by a metallic-feeling mesh, helping the Model Y's cabin feel definitely elevated from the vehicles that came before it.

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.

The new Model Y stretches 4792mm long, 1982mm wide and 1624mm tall, and the practicality perks of the outgoing model still shine strongly in this new version.

Climb into the backseat and you’ll find a seriously spacious area, and one that feels even bigger and lighter thanks to the completely flat floor and the glass roof.

Even sitting behind my own 175cm driving position, there was ample knee and headroom, and the addition of the 8.0-inch rear screen, which supports two headphone connections, is a clever touch. Gone are the mind-numbing days of staring out the window on long family road trips. Now, kids get access to YouTube, Netflix and a heap of games.

There are also two USB charge points, and a pull-down divider that separates the comfortable rear seats. The door pockets front and rear are sizeable, and cabin storage abounds, including a hugely deep storage bin that separates the front seats.

Open the boot, and remove the shade, and you'll find another fairly massive storage area, including a deep hidden area under the boot floor. But you won't find a spare tyre – instead Tesla offers a 24-hour call-out service for the life of the warranty, where someone will come and repair or replace your tyre, should you have an issue.

Tesla isn't good at detailing specifics about its vehicles, but says you can expect a total 2138 litres of storage space in the Model Y, presumably with the rear seats folded flat and measured to the ceiling.

So yes, this Model Y RWD is the cheapest way into the Model Y family, listing at $58,900 before on-road costs – exactly $10k cheaper than the Long Range All-Wheel Drive.

That’s a little more than some of its core Chinese rivals, like the XPeng G6 which kicks off at $54,800, and a lot more than vehicles like the Leapmotor C10 and Geely EX5. But you could argue that Tesla has more brand standing than them in Australia, given it has been around for so much longer. 

Tesla has also jacked up the included features for this update, with heating and cooling for the front seats, new 19-inch alloy wheel designs, adaptive LED headlights, and a very cool 8.0-inch rear screen that gives backseat riders access to games, YouTube and Netflix.

Tech up front is handled by a 15.4-inch central screen on which you can connect your Spotify or Apple accounts, but there’s no Apple CarPlay and Android Auto. The system pairs with a nine-speaker stereo, and there’s still the best wireless charging pad in the business below the screen.

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.

Again, Tesla keeps its cards close to its chest on specific outputs, but data we've seen points to this Tesla's rear-mounted electric motor producing 255kW, a smallish increase from the 220kW of the outgoing model.

Tesla says that's enough to produce a sprint to 100km/h time of 5.9 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.

Again, more cloak and dagger from Tesla here, but most reporting suggests a 75kWh battery is housed beneath the new Model Y.

We do know that our rear-drive Model Y will deliver a claimed 466km driving range on the WLTP cycle.

Charging is capped at a reported 220kW, with the brand suggesting 238km in driving range can be added in 15 minutes when using a 175kW Supercharger. Home AC charging is capped at 11kW.

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. 

Reviewing a Tesla Model Y at the moment is no mean feat. The company's very public figurehead is fighting for a front-row grid position in the battle for world's most unlikeable human at the moment.

But anyway, journalist hat on, personal views aside, Tesla has done a good job with the new Model Y. I actually didn't much like the outgoing model – the ride was too harsh, the steering too darty and the cabin too austere – but Tesla has comprehensively overhauled each of those drawbacks to create a car that is genuinely much better than it has ever been before.

Let's start with the cabin. It's still austere, but the quality feels higher and more premium, and while I'll die on a hill of the screen-controlled drive selector being a bad idea, it is otherwise now a nice place to spend time. The screen and the software powering it largely replace the perks of Apple CarPlay, and the addition of the rear screen is a very good one, too.

But the biggest improvements are in the way the Model Y drives. It's far more compliant on Sydney roads, while the steering sensitivity has been dialled back so it doesn't feel as though you're constantly making corrections.

I also like the power delivery in the RWD. It's not lightning fast, but the grunt is constant and feels really instantaneous and usable.

It's no sports car, though. Our test car took in some of the windiest roads in greater Sydney and beyond, and while the body roll and composure feels on point, the Model Y does struggle with really sharp cornering. The aggressive traction control was a constant passenger on the really challenging stuff.

Overall, the improvements are good, and very noticeable.

This Tesla Model Y wears the same five-star ANCAP safety rating as its predecessor, awarded back in 2022.

Everything you expect is present and accounted for, including seven airbags, auto emergency braking (AEB), lane departure warning and assist (the latter being a little too panicky for my tastes) and cameras front and rear.

Special mention for the brand's semi-autonomous functionality, which – while not perfect – is among the best I've experienced. On the highway, it will stay in the centre of its lane, rather than the bumper-bowling-style swaying that some systems serve up, and change lanes for you when you indicate.

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.

Underwhelming, I'm afraid. A four-year/80,000km warranty might be the worst offered by any mainstream brand in the country. For the record, five-year/unlimited km is now the minimum standard, with many brands far exceeding that.

Servicing intervals are a bit scattered, with the brand instead listing when things need to be done, rather than a traditional schedule.
