BYD Sealion 5 vs Renault Arkana

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.

This time around my family of three has been reviewing the updated Renault Arkana Esprit Alpine mild-hybrid, and you might be wondering… why?

In a market that is positively bursting at the seams with established and new competition, including full-hybrid rivals like the Honda HR-V RS and Hyundai Kona Premium, the Arkana has its work cut out for it.

It’s also a slightly unusual proposition, pairing the raised ride height of an SUV with the swooping roofline of a coupe, while sticking with a mild-hybrid powertrain as more and more rivals make the jump to full-hybrid.

So, does this small French SUV coupe still have enough going for it to stand out from the crowd?
