BYD Atto 1 vs BYD Sealion 8

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?

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?
