Renault Megane E-Tech vs BYD Sealion 7

What's the difference?

The design for the Renault Megane E-Tech is top-notch and the eco-conscious footprint is even better. It’s an easy and comfortable car to be in but the price is a smidge too high in my opinion when you consider there’s currently only one choice for us Aussies and it’s a mid-spec variant at that. It also misses out on some items its rivals have but is a solid EV to consider for urban dwellers.

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.

The E-Tech’s plump body panelling gives me some cute marshmallow vibes from certain angles but there are enough features to keep it looking slick, like the fun LED headlights, massive 20-inch alloys and optional two-tone paintwork.

I’m also a fan of the door handles on the E-Tech as they add some nice focal points, because the front has auto-flush handles that pop out on approach and the back door handles are positioned on the C-pillar.

If you're eco-conscious the E-Tech ticks the box because Renault has designed it to be 90 per cent recyclable.

The body is made of aluminium and can be reformed and shaped into new products at the end of its life. The interior materials are made from recycled fabrics and trims; even the lithium-ion battery is free from any rare earth minerals.

Head inside the cabin and the grey knit trims and upholstery on the seats, doors and dashboard creates a cabin space that feels warm and inviting. It's a similar feel to the Polestar 2 - simple but refined.

Although, with my kid around I have higher anxiety about dirtying them!

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 E-Tech’s cabin is fairly roomy up front with plenty of head- and legroom. The front seats are super comfortable with powered lumbar support and I wouldn’t mind them not being powered if the price point was a bit lower. 

The rear seat is comfortable enough once you get seated but the top of the door apertures are low, and I have to duck my head to get in and out.

Your head also brushes against the roof lining in the back which isn't terribly comfortable, especially considering there is no fold-down armrest to lean on.

The front row benefits the most with individual storage and you get a lot of options to choose from but the centre console is one of the most practical I’ve seen for the class. Lots of pockets and nooks that feature adjustable 'walls'.

You get a single permanent cupholder but with the removable walls, accommodation for a second cup or bottle, can be catered for.

Underneath the multimedia screen you get a dedicated phone shelf, which I love using.

In the rear, you get two map pockets and shallow bin storage in each door.

The charging options are good with two USB-C ports in each row as well as a 12-volt outlet and a wireless charging pad up front but you miss out on V2L (Vehicle to Load) functionality in this model.

The 9.0-inch touchscreen multimedia system looks great headlining the dash and is easy to access and use. The system rebooted once on me while driving but other than that everything is responsive.

You get wireless Apple CarPlay and Android Auto and the CarPlay is easy to get started.

The steering wheel has numerous stalks, controls, regen paddle shifters and even the gearshifter on the column, too. It takes a beat to get used to it but I like how driver orientated it is.

The boot offers great storage at 440L but it’s a deep well, which might be annoying if you’re unloading heavier gear. There is underfloor storage for the cables, too, and like I said, you miss out on a powered tailgate.

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 Techno EV60 has a single electric motor. It produces a power output of 160kW and 300Nm of torque, and Renault says it will sprint from 0-100km/h in 7.4-seconds.

That's perfectly adequate for keeping up with traffic or getting  around town. You only notice a sluggishness with power when you have a full load of gear. Flipping it to 'Sport' mode make it feel peppier, if you ever need it.

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.

The official energy consumption figure is 15.6kWh/100km and I averaged 13.9kWh after a fair mix between urban and open-road driving.

That’s outstanding consumption but the official driving range for this E-Tech’s 60kWh lithium-ion battery is up to 454km, which is similar to the Hyundai Kona Electric but I still had an eye on the range during longer trips.

The E-Tech has a Type 2 CCS charging port which means you can benefit from faster DC charging speeds, however, it can only accept a top speed of 7.4kW on AC power.

On a 7.4kW AC charger, you can go from 0-100 per cent in a little over nine hours but on a standard 2.3kW house plug, that jumps up to over 30-hours. 

On a 130kW DC charger expect to go from 15-80 per cent in as little as 30 minutes, which is pretty convenient if you have access to one.

Sadly, the E-Tech doesn’t have vehicle-to-load capability, so you can’t power or charge bigger items.

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.

I have mostly loved driving the E-Tech. It's easy to cruise around in and the power is adequate for open-road driving but it prefers an urban environment.

The power can feel a bit lacklustre when you are carrying lots of people or gear but you mostly feel that when you're on a steep incline and trying to keep up your speed.

The steering is crisp and that makes the E-Tech very responsive to drive. The power is delivered smoothly and it feels well-balanced when you put your foot down.

There is more roll in corners than I was expecting but the car still feels firmly planted. 

The ride comfort is great. The suspension is more firm than soft which means you feel the road but it's not a major bother. There is a bit of wind noise at higher speeds, as if the door isn’t properly sealed by a millimetre but it doesn't annoy me. 

The regenerative braking is controlled by paddles on the steering wheel and you have three levels plus a one-pedal function to choose from.

The single pedal set-up is pretty smooth, even in stop/start traffic, but it’s great to be able to quickly change modes on the go.

The smaller size of the E-Tech makes it an easy car to manoeuvre in a small car park. You get front, rear and side parking sensors which is great because the reversing camera isn’t as clear as it should be for this price level. 

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.

The E-Tech comes with a five-year/100,000km warranty, but it’s usual to see an unlimited km term for the class. The battery is covered by an eight-year or up to 160,000km warranty term.

Service intervals are reasonable at every 12 months or 30,000km and you also get five-years roadside assistance included.

Pricing over the first five years ranges from a low of $230.04 to a high of $519.62, averaging out at pretty competitive $317.72 per service. No capped-price deal is available.

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.
