BYD Atto 3 vs BYD Sealion 7

What's the difference?

Back in 2022 a friend asked me if they should buy the then-new BYD Atto 3. My advice was to avoid such a new brand, because despite positive first impressions of the electric SUV I couldn’t comment with any certainty on the long-term prospects for BYD.

Well, fast forward to 2026 and things could not be more different. No brand exemplifies the seismic shift in the local car industry more than BYD.

It has emerged not only as the clear leader of the pack from the Chinese car brands, but has done so by taking risks and offering some unusual products. This new Atto 3 Evo is a prime example of that, because while it looks almost-identical to the old model, it has huge changes underneath.

When I say ‘huge’ I mean major upgrades like all-new, 800-volt underpinnings, bigger batteries and even a switch to rear-wheel drive - at least for one model.

BYD is selling one model, with the same name but two very different powertrains and layouts. It highlights the radical changes brought on by the electric revolution in the car industry and demonstrates the flexibility of these platforms compared to internal combustion engine (ICE) vehicles.

And also explains why BYD is no longer just a newcomer with an uncertain future but rather a well-established member of the mainstream market.

But would I recommend buying this new Atto 3 Evo? Read on…

Looking across BYD's line-up, you'd think you were reading the attractions for the local aquarium! And now the Sealion 7 has entered the splash zone, or more accurately, the most popular car segment - the mid-size SUV.

It fights for pole position against the long-running electric favourite, the Tesla Model Y but newcomer Cupra Tavascan also offers some sporty competition.

For this review we're testing the flagship Performance grade to see whether or not it offers family-friendly fun.
