Mercedes-Benz G-Class vs BYD Sealion 5

What's the difference?

Imagine jumping in the time machine, zapping back to the late 1970s and bringing the team that produced the original Mercedes-Benz G-Wagen into 2025 and showing them where their creation has landed close to half a century later.  

They’d be amazed a vehicle looking so much like their military-focused, first-generation model even existed! And once they’d absorbed that incredible fact they’d be stunned to see what lurks under its familiar bodywork. 

Because this is the most recent iteration of what’s now referred to as the G-Glass, the pure-electric G580 featuring four individually controlled electric motors - one at each wheel - collectively producing enough energy to power a small town. 

Stay with us as we explore this take-no-prisoners EV 4WD that has multiple show-stopping, high-tech party tricks lurking up its sleeve.  

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?
