    I'm OCD about my cars, and would like to know exactly what the differences are between a stock Prius and the Touring Prius.

    Is there a Toyota website that might actually describe the differences? Spring length? Shock/struts? Anti sway bar differences?

    I had been wondering that too, and haven't found that there's any mechanical difference for the Touring trim line. Looking at the attached 2018 e-brochure, nothing is described, and the only differences in the Touring specs is the "track," which would be due to the 17" wheels; there are different front lights and rear bumper. The Touring trim was eliminated in 2019, when the Prius lines went to common Toyota L-eco, LE, XLE and Limited - - there's no SE or Sport line.

    There ARE several different OEM part numbers for struts/shocks, front and rear. It's probably VIN specific.

    I know KYB makes the struts for my Avalon Hybrid, and the aftermarket struts/shocks from KYB are stiffer than OEM stock. I'll phone KYB and ask if they make the struts for the Prius.

    Yes...I'm OCD...always curious, mostly late at night when I can't sleep...HAHA!

    The main feature for Touring grades is the 17-inch wheels. Besides the difference in track kindly mentioned by @pjksr02, New Car Features (more info) says the outside front turning diameter is larger (10.4 m, rather than 10.2 m), and the steering overall ratio is greater (13.6, rather than 13.4).

    The Electronic Parts Catalog shows two versions of the steering gear assemblies and shock absorbers, but the same stabilizer bars and coil springs. The spring length is different only for “Rough Road Area Specification” models, which have 20 mm higher ground clearance and don’t seem to be sold in the U.S. mainland.

    For 2019 and later models, New Car Features discloses a more substantial difference in the shock absorbers. Those on Touring grades use a “multi-leaf type linear control valve,” but those on other grades use a “high response type piston valve,” in both cases for “ride comfort and controllability.”
    Yes, they do—or at least, they made the ones on the car that was torn down by the Hiroshima Industrial Promotion Organization.
