    I found the above through searching, but can't seem to find what the Prius Prime steering ratio is, or any newer Prius for that matter. The quote is talking about a 2009 Prius.

    If anyone happens to know what the ratio is, it would be super helpful for me.

    Thanks!

    13.4:1 or 13.6:1 for the Gen 4. I'm not sure if it's the same for the Prime.

    The 2017-2018 Prius Prime New Car Features book (available by subscription to techinfo.toyota.com) says the steering ratio for all grades of the Prius Prime sold in the U.S. is 13.4.

    anyone know if it's the same in the '19 prime, since it has an improved steering angle sensor compared to the 17-18

    The updated New Car Features (more info) says the overall steering ratio is 13.4 for all grades and model years (2017–2020).
