Regal fuel tank capacities?

2011 Regal 2.4
I just bought a 2011 Regal 2.4 German built model last week. I wanted to see what the fuel tank capacity is. The owners' manual says it's either 19.5 or 18.5 gal depending on whether the engine has NU5 and NT7 emissions (19.5) or NU6 emissions (18.5). I don't have a clue what these terms mean or where to find it (one of the digits in the VIN???). Can anybody tell me how to determine which emissions I have?

Thanks very much,

For anyone who's interested, Tricia and I corresponded via PM and the answer is 18.5 gal.
