$NIO Inc (NIO.US)$ 2023 NIO Day on the 23rd is very close, and there are plenty of official spoilers. You must all know that NIO will release a new car, ET9, on NIO Day this year. I took a picture of the car and it will be launched in a few days. My deepest impression is that there is so much black technology. The term “roll” has had the highest number of appearances this year. If NIO wants to push technology hard on ET9, the executive flagship sedan should show off new technology. The official paper is very long. Let's focus on controlling the smart chassis throughout the line. From NT1 to NT2, NIO has always liked to think about chassis. This time, the ET9 chassis will be more intelligent and flexible, and will also link AD to achieve advanced smart driving. Other than this, there are many other hardcore techniques that haven't been released, so it's worth paying attention to. I think it also fits well with this year's NIO Day theme “up”; only when technology is advanced can it be called a flagship.
