Getting an MBA right after college is nearly worthless. You would come out with BAS/BS, BSE and MBA... that is a lot of letters, which is terrifying to employers that see no JOB on your resume. If you are more interested in the business world of engineering, Penn's the place to go; the M&T program opens a LOT of doors if you are successful in it.
I would not be looking to go to grad school right after undergrad, though. Get a job first, work for a few years and THEN get the MBA, when it will actually help you.
