What's the difference?
Ever since the middle of the 1990s, I've been captivated by the Mercedes-Benz S Class. It used to be known as Sonderklasse - special class - and teenage me certainly thought it was. The one that caught my attention was the W140. A huge, two-tonne beast when that sort of mass was rare, it was loaded with amazingness and owned the road.
Part of its unique appeal was that that it was properly ugly. When it hove into view it was like a battleship entering Sydney Harbour. And it used almost as much fuel, with the V12 on board.
Over the years, genuine style has invaded the S-Class and today I found myself, for the first time, in an unusually pretty pair of S Classes - the S560 and S63 Coupes. And, astonishingly, it's the first time I've ever driven an S-Class. So with all that baggage I've built up over the years, they had a lot to live up to.
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.
Both of these vast vehicles are phenomenally comfortable - this is the kind of car that Mercedes does so well, and has done for decades. The S Class is rarely a disappointment but it's difficult to believe that such a big, heavy GT car can also dance the way the S63 does.
The S560 is far more weighted to being a GT - supremely comfortable with that active suspension, a growly, refined V8 and a cabin full of gadgets and comfort. The S63 is altogether more aggressive, to look at and to drive. Lopping the roof off both of them adds weight but, like any cruiser, also puts you out in the sun, the breeze and into your surroundings. Plus, in the case of the S63, you get more exhaust noise.
They're two very different cars and not just because of the engine. After all these years admiring it from afar, the S63 has delivered on my teenage expectations - fast, smooth and utterly mad.
While the BYD Sealion 5 lacks the polish of some more established plug-in hybrids, it has a seriously compelling price advantage over some competitors. It makes a base-model Mitsubishi Eclipse Cross PHEV feel positively outdated and it’s $13,800 cheaper.
BYD's lack of ANCAP rating for the Sealion 5 and the uncertainty around it still being a new brand are downsides, even if BYD is quickly moving past the latter. But being the most affordable PHEV available while having this much showroom appeal is bound to work in the Sealion 5’s favour, just don’t expect a dynamic masterpiece once you’re out on the road.
