Need some clarification on these engineering fields?

<p>Right now I'm filling up applications for college. I'm interested in going into automotive engineering, but I'm confused as to were it's place is. Is it like a branch of engineering i.e aerospace engineer, electrical engineer? I was looking into Cal Poly SLO's website and it had automotive engineering as a field of study under Mechanical Engineering. Does that mean I have to major in M.E and I get to study automotive engineering also? I'm confused and just need some clarification. Thanks.</p>
