I don't have time to look for data for the competitive set but YoY and absolute units performance isn't great for the Z4. Check out page 32 for H1 2012 results and page 34 for FY 2011 results.
My speculation is that the X series of trucks is profitable enough to keep a low volume car like the Z around to pander to the few fans who want it.
