BYD Atto 1 vs BMW 420i

What's the difference?

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?

BMW's new 4 Series blasted onto the world stage with a chonky schnozz on it that only a mother could love. If BMW didn't want anyone to look at the rest of the car, it did a cracking job of it, because everyone had something to say about the big gnashers now grafted to the 4's front end.

I was nervous about it, too, because the 4 Series has always been so elegant and the current 3 Series - on which it is based - is quite nice to look at. It also threatened to overshadow just how good a car the BMW 4 should be, based as it is on the excellent 3 Series.

And, of course, one also had to wonder if a sports coupe like this would be any good around town. Limited vision? Hard to get in and out of? A true four-seater, or just a squishy 2+2? So many questions.
