Tesla Model Y vs BYD Sealion 7

What's the difference?

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.

The BYD Sealion 7 Performance is well-priced and well-equipped. It more than holds its own against its mid-size electric SUV rivals. It has great motor outputs and it handles comfortably on the road. There's a lot to like here but some of the technology needs to be tweaked.

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.

It may be named after a sea lion but it doesn’t resemble the blubbery cuteness of the creature itself. However, its sleek dynamic styling and performance outputs do call forth some of the creature's water prowess. 

This prowess is hinted at by the 20-inch alloys which are fitted with Michelin tyres and red brake calipers. There’s some Porsche-like design notes in the wide swoopy nose and LED headlights. The rear is also quite handsome with its long LED band strip and narrow window giving it a sporty silhouette.

Head inside and the Performance showcases the best BYD cabin I've sampled. There are no strange accents or panelling like there are in the Atto 3. This proves that BYD can do premium well.

The quilted leather upholstery feels supple underhand and the sports seats with integrated headrests reminds you what it can achieve in a sprint.

The swoopy design is carried over inside with the door panels. The dashboard is simply styled but headlined by an enormous 15.6-inch display that can rotate between landscape or portrait mode. Some may liken it to an iPad but it works.

The panoramic sunroof keeps things bright and cheerful but there are some simplistic elements that are hard to ignore. Like the lack of buttons, minimalist mirror cover design on the sunvisors and a rather plain-looking centre console.

Everything else flows and my favourite feature inside is surprisingly the lever door handles! They're functional but cute.

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.

The cabin has space, space and then more space. Passenger comfort is all but guaranteed with the available leg- and headroom in each row.

The functions for the electric front seats means it's easy to find a comfortable position. Door apertures are wide for each row and despite a relatively low 140mm ground clearance, it's still an easy SUV to slide in and out of.

Technology looks great and the large 15.6-inch multimedia display is what catches your eye first. Graphics are sharply rendered and the touchscreen responsive. There's a lot of information and menus embedded into the display which means it's a system that will take you a beat to get used to.

It's not unique but the in-built voice assistant rarely works as it should and needs some work. Also, because of the lack of buttons and dials, all functions are accessed via the screen. I don't like this because it tends to draw your eyes from the road far more often than it should and some functions - like the heat and ventilation for the front seats - are buried in a few menus.

There is wireless Apple CarPlay and Android Auto but there are some gremlins that need to be ironed out. The connectivity is easy enough but the steering wheel mounted phone control didn't access Apple CarPlay. So, I couldn't hang up my phone call properly, it would instead access the Bluetooth phone menu and dial my last call. I had a few 'butt' dials this week because of it.

Storage is on par with the Performance rivals and up front the burden falls across the large glovebox and middle console but there is also a shelf underneath the centre console for bigger items, like a handbag. There are two phone cradles, although only one offers wireless charging, and two height-adjustable cupholders two drink bottle holders and small storage bins.

In the rear, you get two device pockets and a map pocket on the back of each front seat. There is a fold-down armrest with retractable cupholders and a small storage pocket (think Kindle-size) and there are storage bins in each door.

The boot capacity is a decent 500L and the floor can be adjusted to two heights, one offering a level loading space. There is also a frunk storage of 58L for any cables or random bits you don't use often. Under the boot floor there is also enough room for cables and the tyre repair kit. The powered tailgate can be access via your keyfob as well.

For a flagship grade, I would have expected a few extra amenities in the rear, like climate control and sunshades but it does have directional air vents, reading lights and a USB-A and C port.

The Sealion 7 is being offered in only two grades, the base Premium and the flagship Performance that we're testing for this review.

There are only four points of difference between the two grades. The Premium isn't all-wheel drive and doesn't include heated rear outboard seats, a heated steering wheel or dual electric motors like the Performance gets. That creates a $9K price hike to jump into the top-spec grade, bringing it to $63,990 before on-road costs.

It might be starting to sound expensive but it's still more affordable than most of its main rivals. This is because the Cupra Tavascan VZ is priced from $74,490 MRSP and the outgoing pre-update Tesla Model Y Performance comes in at $82,900 MSRP.

What do you get in the Sealion 7 Performance? A lot, it seems. Standard equipment includes electric front seats with heat and ventilation functions, adjustable under-thigh and lumbar supports, panoramic fixed sunroof and leather upholstery, a leather-wrapped steering wheel with mounted controls.

Technology looks top-notch with a crystal clear 360-degree view camera system, a rotating 15.6-inch multimedia system, 10.25-inch digital instrument cluster, coloured head-up display, dual-zone climate control, two USB-A and -C ports, 12-volt socket, V2L capability (via adapter), wireless Apple CarPlay and Android Auto, 12-speaker Dynaudio sound system, over-the-air updates, and satellite navigation.

There's also keyless entry and start, powered tailgate, BYD digital key (via smartphone app), tyre repair kit, rain-sensing wipers, dusk-sensing LED headlights and soundproof double glazed glass on both the windshield and front windows.

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.

The Performance is all-wheel drive and is fully electric with dual motors, a squirrel cage induction motor located at the front and a permanent magnet synchronous motor at the rear. Together they produce up to 390kW of power and 690Nm of torque.

This gives the flagship grade a 0-100km/h sprint time of just 4.5 seconds. There’s obviously ample power to be had here which will delight EV fans who like that tummy-falling sensation when accelerating.

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.

The Sealion 7 Performance has a blade battery with a large 82.56kWh capacity which supports a 456km WLTP driving range. This isn’t terrible for city drivers but a regional driver will likely want a longer range. BYD includes a portable charging cable with the model.

Charging is sorted via a Type 2 CCS charging port which accepts up to 11kW on an AC charger and up to 150kW on a DC charger. On a 150kW DC charger, you can go from 10 to 80 per cent in as little as 32 minutes and that increases to more than eight hours on an 11kW AC charger. All of the figures are quite good and help with the general day-to-day convenience.

The official energy consumption figure is 20.4 kWh per 100km but after doing a healthy mix of open-road driving and city stuff, my average has popped out at 19.1kWh. I reckon it's a solid result for a ‘performance’ grade but I didn’t find the regenerative braking to be particularly strong on this model.

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.

The Performance grade offers plenty of power that is delivered wickedly quick without feeling overwhelming when you have to accelerate. You still feel in control, which is very important when you have outputs like this does.

The steering is responsive and light enough for quick lane changes. The general on-road handling is quite refined but there is more roll in corners than you’d expect and this is the only time the power can make the handling feel a tad wobbly.

Surprisingly, there isn't a one-pedal function and the regen braking isn’t particularly strong. It’s difficult to ‘creep’ forward in this in stop/start traffic where it can feel a bit jerky at times, so it handles best on the open road.

Visibility is mostly good but the rear window is narrow and a digital rear-view mirror would have been welcomed in this model. Suspension is sports-firm but forgiving over bigger bumps. 

The 360-degree view camera and surrounding sensors makes this super easy to park and honestly, you shouldn’t have any trouble manoeuvring the Sealion 7.

The new Sealion 7 has a maximum five-star ANCAP safety rating from testing done in 2025 and scored well across its individual assessment criteria, scoring 87 per cent for adult protection and 93 per cent for child protection, respectively.

The Sealion 7 features nine airbags, including side chest airbags for both rows but it’s common to see these just on the front, so this is excellent. 

When it comes to standard safety equipment, it's almost a case of what doesn't it have? Some stand-out features include front and rear cross-traffic alert, blind-spot view monitor (which pops a video feed of your left blind spot onto the multimedia display) and child detection alert.

Other standard features include lane keeping aid, lane departure warning, adaptive cruise control, forward collision warning, rear collision warning, driver attention monitoring, 360-degree view camera system, and multiple parking sensors.

The autonomous emergency braking has car, pedestrian, motorcyclist and cyclist detection. For pedestrian, motorcyclist and cyclist detection, it is operational from 8.0 to 80km/h. For car detection, it is operational between 4.0 to 150km/h.

There are ISOFIX child seat mounts and three top-tether anchor points and the rear row is wide enough to accommodate three child seats side by side.

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.

The Sealion 7 is covered by a six-year/150,000km warranty which is good for the class. The battery is covered by an eight-year/160,000km warranty which is a normal term.

The Sealion 7 gets a 10-year capped price servicing but it’s expensive compared to some of its peers at $4157.

Servicing intervals are spaced at every 12 months or 20,000km, whichever occurs first.
