  • throttle response in the C8

    Just curious what other members think GM may or may not do regarding the throttle response in the C8. Improvement over the C7? The same? Nothing changed? Thanks!

    All anyone could do is guess. In the C7, the slow throttle response is part of something GM calls "torque management*," and is designed to lessen strain on the drivetrain by preventing full application of torque instantaneously. Also, probably, to help inexperienced drivers keep the car pointed straight.

    With no driveshaft / torque tube, that eliminates one point of concern. The extra weight over the drive wheels improves traction, which lessens wheelspin. We don't know what the torque limits of the new DCT are. And I wonder if less weight on the front wheels increases the difficulty of keeping the car pointed straight.

    We won't really know anything until C7 owners get their C8s and can compare.

    * Torque management also prevents full throttle application (no matter how hard you mash the pedal) at slow speeds in low gears (1st & 2nd, IIRC). Even using one of the electronic throttle curve modifiers, like the Vitesse, won't eliminate that.

      DCT with a NA motor should make it be very responsive, the electronics can control the sensitivity. You don’t want it to aggressive and knowing that the mode selector will make a difference.

        .
        At some point in time independent testers, journalist, public will be allowed access to drive the C8. Will probably be before first customer deliveries.

          True, but the issue some owners have with throttle response on the C7 isn't something I ever read about in the media. I doubt it's something the car mags or blogs will address this time, either.

            0 to 60 mph in less than 3 seconds how much delay in throttle response can there be?

            i believe the various race, sport or other mods determine the sensitivity of the throttle actuation..

              I had no issues with throttle response on my 2014 but it was a 7 speed. Expect different response curves in the different modes, the C7 had that. In track mode it was tough being smooth at part throttle. One nice improvement is you can mix and match modes in the C8 so if you want the track throttle and engine map combines with tour steering and suspension you can now do that.
