My guess is that it will fit any 2016 or 2017 Prius. What I know for sure is that it fits my 2017 Prius Three and that the part number for the Roof Rack is PW301-47005. The dealer did not have the car that I wanted and I'd established that I didn't want a roof rack. So when my salesman went to pick up the car that nearly matched what I wanted, he made sure that they didn't install the roof rack and that it remained in the box for me to sell if I wanted to. Evidently there are federal regulations that require that the dealer must provide the equipment that is stated on the factory invoice which in this case included the roof rack. Its MRSP is $299.
