Per previous posts we have laminated "double" glass on the 760i here in the U.S.It is standard laminated and not identified on the stamp as "acoustic".It does provide superior sound insulation over single pane tempered glass.Also, there is apparently a problem with the mirror assembly that is causing some noise issues on certain cars.I would encourage you to do a little more research as to what your specific desired model would have.I'm thinking the EV cars would, at least, have laminated side glass.The 740i has tempered side glass.As previously stated BMW doesn't seem to put a lot of emphasis on upgraded glass tech.
