Mercedes-Benz E400 vs Leapmotor B10

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. 

The B10 isn’t Leapmotor’s first car in Australia - the C10 has been here for more than a year now - but for many it might bring about the first time they hear about the Chinese brand.

The 2026 Leapmotor B10 lands in Australia promising to be the most European of its Chinese compatriots, with the brand’s connection to Stellantis giving it access to other brands under the company umbrella like Alfa Romeo, Maserati and Peugeot.

At its local launch, we get behind the wheel in scorching south-east Queensland to find out if that holds true for this electric small SUV, and to see if the B10 can bring with it a better first impression than the already-arrived mid-size C10.
