    Does anyone know if the steering lock to lock is larger (longer?) in this car than with the Gen 2? I love the steering feel of the Prime. Everything is perfectly weighted and just the right amount of feedback comes through the wheel, but I notice on twisty descents that I have to turn the wheel more than with my 2007. I also notice that the turning circle is slightly better too.

    That's weird nobody has replied yet. I found a 2004 C&D gen 2 review and it said that the steering ratio was 19:2:1. The turns lock to lock is 3.7. Turning circle is 34.1 ft. Here is the gen 4 and prime turning circles. Four Touring wheels ruin the tight turning circle. Screen Shot 2017-07-21 at 4.13.47 PM.png Screen Shot 2017-07-21 at 4.20.04 PM.png

    Looks like the new Prius does potentially have less tight steering if the radius increased and lock to lock still feels the same

    Finally found it.

    13.4 for most Gen 4s. 13.6 for Tourings. The weird thing is that there is a 15" wheel specification that also has 13.6:1 steering ratio.
