What is the difference between the BMW 2006 325i and the 2007 328i?

I am new to BMW, so originally I thought that there were only 2 in the 3 series (the 325, and the 330 with the larger engine). Now they have the 328i this year, and I don't see a 325. What's the method behind their number system,What is the difference between the BMW 2006 325i and the 2007 328i?Per wikipedia:

Looks like the only difference would be in head design, internal parts, exhaust restriction and tuning giving more horsepower to the 328.



Typically the 3 is the series and the 25, 28, 30 is the displacment in Liters. 2.5 L, 2.8 L, 3.0 L.

However in this case, there is no actual difference in displacement as there usually is between BMW's. Appears that they are using the same block for all the engines from the 325-335.



They had previously done this with the 323/325 in the E46 generation. Both were 325 blocks with different tuning and restrictions.





Oh, and 328i - 325i = 3i...you would get "3" the i's would cancel.What is the difference between the BMW 2006 325i and the 2007 328i?
