Sonata N-Line not P plate approved in Vic despite being on the 130kw/t limit?

Hi all looking to get a sonata n-line for my son and noticed it has a power to weight ratio of 130kw/t and is not P plate approved in Vic. The regulations say a car must be 130kw/t or under and it is within these regulations and says it’s not P plate approved both on red book and the Vic roads website. This question was already raised by someone else in this subreddit but they were downvoted and go told to do more research. Any help would be appreciated. Thanks
