Tesla Model 3 vs BYD Sealion 7

What's the difference?

Tesla has done enough with the introduction of this Premium Long Range RWD variant to keep the Model 3’s head well and truly above water in an increasingly competitive segment. After more than six years it still looks good, with a pleasant cabin environment, plenty of performance and leading energy efficiency. Safety is top-shelf and it stands up well in terms of practicality and driving dynamics. 

That said, the ownership proposition is average, the determination to make so many functions screen-based is frustrating and the optional Full Self-Driving system is unconvincing. With the Model S and Model Y now discontinued globally it will be interesting to see how the Model 3 continues to evolve.

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.

After four years in market, a heavily upgraded version of the Model 3 arrived in Australia in 2023, the biggest visual changes being a reshaped bonnet, aero massaged overall profile and angular slimline headlights.

The boot lid now incorporates a lip spoiler and the tail-lights were remodelled to create a truncated, two-layer effect. And in true Tesla fashion, the standard 18-inch alloy rims are fitted with matt black-finish aero elements filling the gaps between the satin black wheel spokes. Two new body colours - ‘Stealth Grey’ and ‘Ultra Red’ - were recently added to the available palette. For reference, our test car's finish is 'Quicksilver'. 

It’s still clearly recognisable as a Model 3, but these relatively minor design changes have helped the mid-sizer keep up with the slew of sleek newcomers it now faces.

The interior was also given a substantial makeover, the expansive 15.4-inch central display screen backgrounded by an all-new wrap-around dash and revised console treatment, the former featuring a raised insert and the latter a two-device wireless charging station.

Introduction of this Premium Long Range RWD model also brought the small but significant addition of a physical indicator stalk on the left-hand side of the steering column, replacing buttons on the steering wheel. Big ergonomic tick for that.

Customisable ambient lighting lifts the tone, soft materials look and feel good and the doorcards, bins and armrests have been reprofiled into a more sophisticated arrangement.

Our test car’s dark grey and white synthetic leather trim combination lifts the mood as does light from the huge, two-panel glass roof. But beware, while white trim looks dazzling on the showroom floor it takes some extra work to maintain its schmick appearance in the day-to-day grind.

After seven years in market the Model 3 has aged well and still looks sleek and contemporary.

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.

At just over 4.7m long, more than 1.8m wide and a bit over 1.4m tall (with a 2875mm wheelbase) the Tesla Model 3 is a low-slung medium-size sedan. 

There’s plenty of space up front, a feeling enhanced by the standard panoramic glass roof and our test car’s white trim brightening up the cabin.

There are long, wide bins on the front doors with enough room for large bottles, a slim glove box (which opens only via an on-screen button, which is annoying) and a generous lidded storage box between the seats that doubles as a centre armrest.

The console houses two cupholders with another storage cubby ahead of them (both with sliding covers over the top) and the dual device wireless charging bay on the lower part of the dash under the media screen.

Switching to the rear, at 183cm I have a surprising amount of foot, leg and headroom when sitting behind the driver’s seat set to my position. The rear door aperture is surprisingly large which helps entry and egress.

Technically able to accommodate three passengers, the back seat is best for two full-size adults on anything other than a mid-length journey, although the flat rear floor helps ease pressure on the centre occupant.

There's a well-hidden fold-down centre armrest with cupholders, there are useful bins in the doors and hard shell map pockets on the front seatbacks.

The crisp 8.0-inch rear screen is a welcome entertainment option for back-seaters and there are adjustable air vents underneath it.

For power and connectivity there are two USB-C ports and a 12-volt socket in the front compartment, a USB-A in the glove box (mainly for dash cam and ‘Sentry Mode’ data storage) and two USB-C ports in the rear under the vents.

Boot space is a ample at 682 litres (the bootlid is adjustable for opening height) with an 88L ‘frunk’ in the nose. And if you need to tow a relatively light load like a box trailer or Jet Ski (or two) you can hook up a 1.0-tonne braked trailer (750kg unbraked).

While we understand it helps maximise battery space and reduce weight, we’re not on board with Tesla’s policy of providing a repair/inflator kit rather than a physical spare tyre. Even though this is likely to be a primarily urban cruiser, it’s not good enough. 

Then, there’s the Tesla app, an electronic Swiss Army Knife that facilitates everything from remote vehicle access and cabin ‘preconditioning’ to planning your route (complete with charging stops) and monitoring Sentry Mode (checking the vehicle’s surroundings and receiving alerts of potential threats).

The list of functions goes on and on, but suffice it to say the app is hugely handy. For example, ‘Dog Mode’ keeps the air con on with the car locked for the benefit of your four-legged friend and lets passers by know the doggo is safe via a bold message on the central screen. An internal camera, accessible via the app, lets you check-in remotely, too. Nice. 

Given its overall size and despite its conventional sedan configuration, the Tesla Model 3 offers efficient packaging and a heap of thoughtful features to enhance everyday practicality.

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.

The Tesla Model 3 Premium Long Range RWD is powered by a single permanent magnet synchronous electric motor producing a handy 235kW and in excess of 400Nm.

It sends drive to the rear wheels only via a single-speed, direct-drive automatic transmission. 

Kerb weight is 1747kg and Tesla claims 0-100km/h acceleration in a rapid 5.2 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.

Tesla claims a WLTP range of up to 750km for the Model 3 Premium Long Range RWD, the official EV term for which is… a lot. 

As mentioned earlier, at the time of the car’s local launch in October last year Tesla claimed it as the longest-range EV in Australia and at the time of writing nothing had arrived to change that.

Unlike the standard Model 3, which is powered by a CATL-sourced LFP battery, the Long Range RWD is fitted with a lighter, more energy dense NMC pack from LG with a total capacity of 82kWh (78kWh usable).

In terms of energy consumption, Tesla claims 12.5kWh/100km on the combined (urban/extra-urban) cycle and on test we experimented with liberal use of the accelerator pedal, higher than average freeway running and keeping the car constantly chilled during extremely hot weather, which resulted in an average of 15.7kWh/100km. 

Aside from that, more typical stop-start urban driving with occasional use of the ‘Chill’ (eco-focused) mode brings the number down to 13.1kWh/100km.

That’s an impressive performance, with even the upper test figure more than acceptable for a 1.75-tonne electric sedan.

Capable of accepting a 250kW fast charge, Tesla says the Model 3 Long Range RWD can take on 311km of range in 15 minutes, at that speed.

On a 150kW pylon we saw capacity go from 15-85 per cent (theoretically, 600km of range) in roughly 50min, although the charger fluctuated below peak output throughout.

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.

So, surprise, surprise, the Tesla Model 3 Premium Long Range RWD is quiet. But it’s quiet, even in the context of other EVs in this part of the market.

That’s thanks in part to acoustic glass in the front, rear and side windows as well as the dual-pane glass roof and the Bridgestone Turanza T005 EV tyres (235/45x18) featuring ‘B-Silent’ technology. Corny, but it works.

A kerb weight under 1.8 tonnes is relatively lightweight for an EV of this size and the Model 3 RWD is quick with 0-100km/h acceleration in a fraction over five seconds. There’s always plenty of pulling power under your right foot. 

Suspension is double wishbone front, multi-link rear and ride comfort is respectable rather than exceptional. Smaller bumps and irregularities find their way into the cabin but never to an alarming degree.

Steering sits in the middle-of-the-road between tactile and wooden, which is par for the EV course, although it's accurate and pleasingly progressive. Body roll, even in enthusiastic cornering, is modest. 

The physical brakes are ventilated discs front and rear although they don’t come into play all that often because the Model 3’s regenerative braking system is so good. Single-pedal operation soon becomes the norm. 

Our test car’s optional ‘Full Self-Driving (Supervised)’ will set you back $10,100 as a one-off payment, or $149 per month and Tesla says when using it, “Under your supervision, your car will be able to drive itself almost anywhere with minimal driver intervention”.

We engaged it for a 30km trip through suburbia, across the Sydney Harbour Bridge and into the city’s inner south. 

A rainbow-coloured magic carpet in front of the car graphic on the nav map tells you the system is engaged and although things went smoothly at first we soon sliced a bit off the inner oncoming lane as we turned right at a T-intersection, which was alarming. 

The system also has a consistent tendency to stick to the far right-hand side of the lane, stay five to 10km/h under the signposted speed limit and it continued to operate without my hands on the wheel, although I kept them there for 99.9 per cent of the drive (which is tiring when you’re not doing the steering).

Having been squeezed to the point where we couldn’t merge safely into a particular arterial road the nav took us on what’s known in the trade as a wild goose chase that had to be nipped in the bud. If I hadn’t known my way around it could have been a huge waste of time and (vehicle) energy. As much a nav issue as an FSD one, but overall, let’s just say, I’m not convinced.

Under the heading of miscellaneous observations, I’m not a fan of the on-screen gear position slider in place of a physical control. It’s needlessly fussy, although its ability to automatically switch between D to R (and back) during slow-speed manoeuvres is helpful. 

The software behind the car’s multitude of functions is exceptionally good, as is the ability to swipe in the vicinity of the temp and audio volume screen sliders, rather than having to hit them bang on and the blind-spot camera view which pops up on the screen when indicating on either side is handy.

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.

From January 1, 2026 all new Teslas sold in Australia have been covered by a five-year, unlimited kilometre warranty (including roadside assistance for the duration), up from four years/80,000km, previously.

A big step forward, no doubt, but that just gets Tesla to a base, mainstream market level with a dozen brands now at seven years, several at eight and three at 10 years (conditional).

The drive battery is covered for eight years/192,000km, which is in line with the category norm. And a Body Rust Limited Warranty covers rust perforation for 12 years, unlimited kilometres, which is reassuring.

Tesla servicing is condition-based, so there’s no fixed schedule, with a summary on the car’s touchscreen providing a record of when vehicle maintenance was last carried out and prompts for when they should be performed next.

In the absence of a combustion powertrain the emphasis is on things like wheel rotation, balancing and alignment, brake fluid testing, air-con servicing, camera precision, radiator cleaning and high-voltage battery maintenance.

Theoretically, if a workshop visit is flagged in the car’s system, it could include actions like a ‘Vehicle Health Check’ ($270), ‘General Diagnosis’ (270 per hour), brake fluid flush ($240.80) and replacement of both cabin air filters ($106.60).

Things like air-con desiccant bag replacement ($89.18), tyre rotation ($81.00), a wheels check - if tyre wear is abnormal ($81) and a wheel alignment ($225) are also set inspection and service items. All prices exclusive of GST.

In the States, the brand provides a range of estimated annual service pricing of between US$257 - US$499 ($367-$712), based on data collected by car buying specialist CarEdge. The suggested service range is around 20,000km and the first five annual estimates are at US$300 ($430) or less.

Tesla has 25 stores in Australia, not surprisingly covering mainly urban and larger regional centres, including four each in Melbourne and Sydney, three in Canberra, two each in Adelaide, Brisbane and Perth as well as one in Hobart.

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.
