BYD Sealion 5 vs BYD Atto 3

What's the difference?

This is the most affordable plug-in hybrid available in Australia – as this review is published – but it’s got a lot more going for it than just that.

The 2026 BYD Sealion 5 is a mid-size SUV wearing a BYD badge that has been thrust into the public’s awareness by the popular BYD Shark 6 – as well as by widespread criticism of brand's less popular aftersales shortcomings through much of 2025.

It’s also a plug-in hybrid that is showing up as the nation faces a fuel crisis, despite many remaining sceptical of going ‘full EV’.

The Sealion 5 has a long list of features, of course, plus a claimed four-figure driving range. Is this BYD too good to be true?

We grabbed the entry-level Essential to find out.

Back in 2022 a friend asked me if they should buy the then-new BYD Atto 3. My advice was to avoid such a new brand, because despite positive first impressions of the electric SUV I couldn’t comment with any certainty on the long-term prospects for BYD.

Well, fast forward to 2026 and things could not be more different. No brand exemplifies the seismic shift in the local car industry more than BYD.

It has emerged not only as the clear leader of the pack from the Chinese car brands, but has done so by taking risks and offering some unusual products. This new Atto 3 Evo is a prime example of that, because while it looks almost-identical to the old model, it has huge changes underneath.

When I say ‘huge’ I mean major upgrades like all-new, 800-volt underpinnings, bigger batteries and even a switch to rear-wheel drive - at least for one model.

BYD is selling one model, with the same name but two very different powertrains and layouts. It highlights the radical changes brought on by the electric revolution in the car industry and demonstrates the flexibility of these platforms compared to internal combustion engine (ICE) vehicles.

And also explains why BYD is no longer just a newcomer with an uncertain future but rather a well-established member of the mainstream market.

But would I recommend buying this new Atto 3 Evo? Read on…
