Land Rover Defender vs BYD Sealion 5

What's the difference?

This feels wrong to say this, but it’s so refreshing not to be driving an electric vehicle. There I said it.

After testing so many EVs lately reviewing a car that has an actual engine is a nice change. And this car definitely has an internal combustion engine - it's the Land Rover Defender Octa Black with a twin-turbo petrol V8.

The Defender Octa is the ultimate form of the 110 Defender. It’s wilder looking, more powerful and more capable, while the Black edition adds darkened elements inside and out for even more visual appeal.

While the Defender Octa Black is special, it’s not alone in a world of high-performance luxury SUVs and its head-to-head rival would be Mercedes-AMG’s G63.

I had the Defender Octa Black for a week and while I didn’t take this beast off-road where it is superbly capable, I put it to the test on some challenging tarmac as well as some challenging real-world family duties.  

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?
