Does anyone know what engine is a 2021 BMW X3 30i (B58???), and what engine is in a 2021 X3 M40i?

I believe it's:
B48 for the 30i
B58 for the 40i

Yours is a B48 (4 cylinder petrol) the six cylinder petrol is the B58.

I think for US market cars it's a b46 for the 30i. It's essentially a b48 with some emissions mods.

You don't need a BMW tech to answer a question.
B48 is not in the G01 X3, all these posts are incorrect guesses.

OP your 2021 X3 30i has a B46 engine. Depending on your manufactured date. You can have a B46TU or B46D for the USA 2.0L I4 Twin Scroll Turbo.
The M40i has a B58.
