C8, will it also have the Ackerman effect?

    The whole brilliant concept of Ackerman geometry is that it has almost no effect at small steering angles (by definition, high speed turns are at small steering angles), and noticeable effect only at large steering angles (u-turns, maneuvering in parking lots, etc.).

    Corvette track (distance between centers of left and right tires) is about 5 feet. Cornering around a skidpad of 200 feet radius, the inside wheel is traveling around a 200 foot radius, and the outside wheel is traveling around a 205 foot radius. That's only a 2.5% difference, pretty minimal.

    But around a tight 20 foot radius circle, the outside wheel is traveling around a 25 foot circle- a 20% difference.
    Thanks centerpunch. I love learning new info. Welcome to the forum!

      I changed over to Michelin all season tires on both my C7s....problem solved. I'm hearing the base C8 will also have all seasons, so hopefully not a problem.

The inside tire turns a tighter radius than the outside tire. If both tires are turned an equal amount, one of them is going to scrub.
        Yes, but you are my Guru <wink>
        What I am asking is why NOT using the Ackerman principal helps cornering on the track?

          the steering vector will be variable at slower speeds.
          Thats a huge technological step. Anyone know which magazine?

            GM announced that there will be no front end shuddering on the C8.
