What are the key differences between the BMW X4 and X3 models?

I am considering purchasing either the BMW X4 or X3 but I'm not sure which one would be a better fit for me. Can you provide some insight on the notable technical differences between these two models?

The main differences between the BMW X4 and X3 models lie in their design and dimensions. The X4 has a sleeker, coupe-like design while the X3 has a more upright and spacious design. In terms of size, the X4 is slightly longer and lower, which may affect interior space and cargo capacity.

Another notable difference is the available engine options. The X4 offers a more powerful engine lineup, including a turbocharged six-cylinder option, while the X3 offers a turbocharged four-cylinder as the highest engine option.
