Mercedes-Benz E400 vs BYD Sealion 8

What's the difference?

It is hard to immediately think of a country more suited to the convertible life than Australia. Even our coldest states (you know who you are…) are blessed with more warming sun than almost anywhere else on the civilised parts of the planet, so you’d think we’d be swanning about in dropped-top bliss almost year round.

But it’s actually in the UK (despite being cold, grey and almost always underwater) that convertibles really fly out of dealerships, with sun-starved Brits buying more than anyone else in the world. Weird, right?

Still, here they remain something of an oddity, sold in small numbers to drop-top diehards. At least partly because the convertibles of old were almost always slightly worse than their hardtop equivalents. 

But Mercedes - which makes more convertibles than most - claims to have mastered the soft-top formula with the E400 4Matic, a car it says offers all the perks of open-air motoring without any of the dynamic or practical downsides. 

As the flagship variant, the BYD Sealion 8 Premium all-wheel drive makes a big first impression as it arrives with seven seats, a plug-in hybrid powertrain and a features list that reads like a wish list.

It’s also stepping into a competitive space, lining up against the Chery Tiggo 9 Super Hybrid, Kia Sorento GT-Line PHEV and Mazda CX-80 P50e Azami - all promising similar blends of efficiency, space and value for Australian families.

The Sealion 8 Premium looks like a strong contender on paper … but does that translate to the real world?
