Mercedes-Benz Eqc400 vs BYD Sealion 5

What's the difference?

The Mercedes-Benz EQC has been on sale in Australia for a little while now, and aside from the local launch event we haven’t had a chance to spend any quality time with the brand’s first fully electric SUV. Until now.

The EQC 400, as it’s officially known, is the German luxury maker’s first foray into the full-EV landscape, and could arguably be seen as the first true luxury electric SUV on sale in Australia. I mean, yeah, there’s the Jaguar i-Pace, but it has a more premium-sporting intent than the EQC, and the Tesla Model X isn’t aimed at a luxury customer, more so a technologically-minded buyer.

So what’s the Merc EQC like to actually live with? We drove it for a week to find out.

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.
