Hyundai Ioniq vs BYD Sealion 5

What's the difference?

Hyundai's Ioniq range is nothing if not a flex in the face of Toyota.

Sure, Toyota has a dominating position in the Australian market, with its well-received range of hybrid models, but what happens after hybrid? Hyundai takes on the blocky Prius formula with not only a directly competing hybrid model, but a plug-in and a fully electric version, too.

This expansive range is as though Hyundai is trying to demonstrate it's ready for any future, near or far, and guess what, Toyota? Anything you can do; the Korean juggernaut thinks it can do better.

These cars aren't really designed to sell so much as they are offerings for early adopters, but a few years after its launch, with a host of rivals set to take it on, and an entire sub-brand based on the Ioniq just around the corner, is Hyundai's top-spec Ioniq electric  worth a look? I took one for a week to find out.

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?
