BYD Sealion 5 vs MG MGS5 EV

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.

MG’s latest electric vehicle has arrived in Australia. The MG S5 EV replaces the super popular MG ZS EV. But don’t think of the MG S5 EV as just a replacement because if first impressions ring true this small budget electric SUV could be the new benchmark for the class. 

The arrival could not be better timed. A multitude of new Chinese brands have been landing in Australia with small affordable electric SUVs such as the BYD Atto 3, Chery Omoda E5 and Zeekr X, while the MG ZS EV was getting older and uncompetitive even if its price was almost unbeatable. 

Now the S5 EV has landed and our first impressions show it to be outstanding. We’ve tested it and can tell you how well it stacks up against the ZS EV and after you read this review you'll also know how well it may compare to its small budget electric SUV rivals.
