Mercedes-Benz E400 vs BYD Atto 1

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. 

Back in 2010, Mitsubishi released Australia’s first mainstream electric vehicle (EV) in nearly a century.

That model, the i-MiEV, was a four-seater city-sized Kei car from Japan that cost $48,800, before on-road costs, or from roughly $70,000 in today's money. Little wonder it bombed. That was four times more than petrol-powered equivalents of the time.

Now, in 2026, the new BYD Atto 1 is the first EV sold here since the i-MiEV’s 2013 departure to be considered a four-seater city car.

It’s also the least-expensive EV money can buy, being even cheaper than many internal-combustion engine alternatives like the Mazda 2 and Toyota Yaris hybrid. The fact is, there’s nothing remotely near the Chinese supermini’s base price that’s electric.

But is the Atto 1 any good?
