Straight PC-12 had a lower gross weight than the PC-12/45. The /45 stands for 4500 Kilos. The /47 jumps up to 4740 K for MGW. Also with the /47, they lightened up the roll response which was heavy for a light plane. The /47E has a boost in engine power as well as Honneywell Apex cockpit. The cruise increases a bit for the /47E (also called the NG for Next Generation) as well.

The cabin is pretty much the same for all models. 6 seats standard, with an option to add 2 more in the corporate configuration. Some of the older ones had a 3 seat bench in the back, but haven't seen that in quite a while. In typical configuration, they all have a forward lav. The cargo door in the back is on all models.
