Here's more info on some of the mentioned features.
No Start Button
Similar to the system in Teslas, this car has no start button. Instead, to start it, all you have to do is get inside and put your foot on the brake. From there, you can put the car into gear and go on your way. To turn it off, simply come to a stop and put it in park, and the car will shut off.
ID.Light
The 54-LED strip running across the car’s dashboard is used to easily convey important messages to the occupants. It uses different colors and patterns to signify alerts, navigation prompts, and vehicle charging status, among many other things.
Column-Mounted Gauge Cluster
Rather than fixed in place on the dashboard, The ID.4’s gauge cluster is mounted to the steering wheel. The main advantage of this is that when you adjust the steering wheel, you never have to worry if it’s now in the way of your gauges, as they move together.
Interchangeable Cupholders
While the concept of movable cupholders is nothing new, the way Volkswagen does theirs is a little different. The cupholders in the ID.4 can be stowed away in the center console to get some extra space between the seats, or replaced with the included dividers to keep items in place.
Adjustable Rear Cargo Floor

The ID.4’s trunk floor is on a rail system, so it can be moved up or down depending on whether you want a flat load floor or more space. Additionally, it can be flipped up to reveal another cubby under the floor for some extra storage.
