The more powerful AMG motor may be an option, but I expect it to be pricey, and like the IPL G or Q or whatever it is now.

That said, I am expecting the new Z to be only marginally different from the current model at this point -- I'm open to being mistaken and (hopefully) pleasantly surprised, but the new G is pretty much just a refined version of the old one, and the Z tends to follow that, so...
