I've been happily driving a BYD Atto 3 for ~6 months now. Very happy with it, its got a lot of nice software and hardware features, carplay/android auto works well, driving is nice and very smooth (especially on sport mode), and my daughter loves playing with the "strings" on the doors. The most glaring issue is the battery which is really its weakest part.

Is it better than a Tesla? Probably not - there are clearly places in the software where I know that Teslas are more polished (e.g. the "360" parking view which IMO could be a bit better, although I feel like I'm parking in gta 2), and the acceleration won't blow your socks off. However, they're much cheaper and it's a good family car (for us) - definitely for the price.

What are the issues? I thought BYD batteries were as good as they get?

I am pretty sure Teslas sold in my country (NZ) have BYD batteries.

If OP is comparing their experience in your BYD to Tesla's marketing material, that's not a correct comparison. Tesla battery ranges should generally be derated quite a bit to align them with how the rest of the industry measures range.

And that goes only for rather flat terrain and non-cold environments. Otherwise the discrepancies end up just like consumption of ICE engines in ads vs reality.

Perhaps subjective but in my own experience range on tesla is slightly more then what was rated.

BYD atto 3 that OP mentioned:

- 420km wltp range on 60 kwh battery.

Tesla model 3 rwd:

- 554km wltp with 18" wheels - on 56kwh battery.

so tesla is much more efficient while cost difference isnt that much at least in europe. (41k vs 39k)

you are comparing a sedan and suv though. byd seal is a better comparison to model 3

Allright,

byd seal 46k euros, 570km wltp, 82.5kwh battery

tesla model 3, rwd, long range, 46k euros, 702km wltp (18" wheels), 78.1kwh battery

Tesla has quite impressive effiency... at same price with less battery...

Tesla had to get the price down because of BYD.

Competition is good!

What's real world side by side testing show?

WLTP is a standardized test with real world conditions.

It makes it easy to compare range under same conditions.

if you want anything more I'm sure you can search yourself and come to any conclusion you want. Perhaps even share here if you want.

Battery is fine by itself, but I'd say that the range is somewhere between 315-350km depending on terrain etc. Definitely not the 420km that's advertised. I knew this beforehand from reviews so it wasn't unexpected, but I'd be pretty angry if I didn't read about it from reviews before I got the car.

For me it's fine as I still only charge once a week and I still have around 70%-80% usually, unless I visit remote relatives. I could probably stretch and recharge every other week if I really wanted to, but I prefer to have it ready as we sometimes do have longer drives.

Basically every electric car gets about 75% of its advertised range though. Except maybe the Porsche Taycan.

Rivians are very accurate

FWIW Tesla doesn't have 360 parking camera support. They have a digital visualization and a few cameras pop up, but no full 360 camera setup.

TBH the 360° camera is not really missed if you know how to drive
