不是，马斯克说的新平台实际上是同一平台，但是电路系统改进，除了车身上半部分结构不同，其他所有机械部分完全一样。如果都不改进只改车身形状，10%的费用可能都不用。
When talking about making a new platform for Model Y, Musk previously said that Tesla will get rid of the 12-volt battery architecture. It means no more lead-acid battery and a different way to power in-car electronics. Musk says that it will reduce the overall wiring significantly and simplify the production process.
Less wiring harness means easier automation in the production process and Musk plans a completely different – more automated – production line for the Model Y.
