Doing a little more searching, it looks as though it was actually a very close race between the E82 and the E93. Both ended with MY2013. However, somewhat surprisingly, it appears that the E93 was actually produced a little longer:

As an aside, for the current generation vehicles, you can see from our future vehicle thread:

That the F22/F23 2 Series and F87 M2 will be in production for about a year longer than the F32/F33 4 Series and F82/F83 M4.
