I agree that BMW should bring some other engine offerings to the US, but there are two things that will likely make that not happen:
1. Most Americans still don't like diesel. Founded or unfounded, it's not a popular fuel here, and most people associate it with large trucks.
2. BMW presents themselves as a high end brand here, and offering other smaller, cheaper engines would likely not fit that image.

Now, what's wrong with the cars being cheaper here? Our vehicles are so inexpensive because most of what is bought here is built here, in one form or another. Or at least they come in from Canada or Mexico on rail or truck, not requiring a long boat ride. The reason that vehicles are so much more expensive abroad is tax. I'm not an expert here, and I haven't looked at every country, but I know a handful tax a car up to 100% of its value. We don't do that.
