Well curiously, for MY 2009 the BMW USA owner's manual PDF lists the capacity of a 328i coupe as 16.1 gallons, including reserve of 2.1 gallons, and an E92 M3 as 16.6 gallons, including reserve of 3.3 gallons.

I was kind of surprised, but at least for these two examples the M3 has a LARGER tank.
I would have said they were the same size before I looked.
