BYD Sealion 5 vs Renault Koleos

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.

There’s no shortage of models to choose from if you’re after a family-friendly medium SUV. The problem is, it might take a while to get your hands on one, with lengthy wait times for some of the best sellers due to current delays caused by a global parts shortage and supply chain dramas.

But there are a handful of models with healthy stock in dealerships right now and available for immediate delivery. One of them is the Renault Koleos. 

It's coming to the end of its life cycle and lacks the shine of some of its fresher rivals, but it’s a lot of car for the money. 

We spent a week with the limited edition Koleos Black Edition to see if it is worth a trip to your Renault dealer, or if you should sit tight and wait for one of its newer rivals.
