What is the difference between the BMW X3 and the X3 M?

I am considering purchasing a BMW X3 but noticed there is also an X3 M available. What are the technical differences between the two models and which one would you recommend?

The main difference between the BMW X3 and the X3 M is the engine. The X3 M features a more powerful engine with a higher horsepower and torque, resulting in faster acceleration and a sportier driving experience.

Aside from the engine, the X3 M also has upgraded suspension and brakes, as well as a sportier exterior design.
