Hey @arfung! It's possible that the ID.4 is going to have a similar sound system as the Skoda Enyaq.
Like the Skoda Enyaq, ID.4 will be available in a variety of engine and battery configurations. The top model gets four-wheel drive and up to 500 km range. But where we know that Enyaq gets Canton sound system as a premium option, we still know little about what kind of sound comes in VW ID.4. But since the smaller ID.3 is offered with an extended stereo system from Beats, it is reasonable to believe that they also have a hand in the game on ID.4. We keep our eyes (and ears) open.
