    Throttle-by-wire question

    A friend and I were talking sports cars over a few beers and I think he had one too many. He told me that the 996 generation is throttle-by-wire (not a cable throttle - a digital throttle) and Porsche's software cuts the throttle signal as soon as the brakes are applied. Is this true? I can't believe that this can be true because it would eliminate the ability to heel-toe braking & down-shifting, essential in driving any sports car the way it should be.

    Thanks

    Re: Throttle-by-wire question

    Yes, the newer 996s (MY 2000 forward, I believe) have electronic throttle, and it is not cut off when applying the brakes.

    Re: Throttle-by-wire question

    Great, I didn't think so.

    Thanks for the quick reply poursha.

    Re: Throttle-by-wire question

    Other manufacturers, such as Mercedes, who use throttle-by-wire, do cut the throttle when the brakes are applied.

    Maybe there is an issue with the auto trannies?

    It can't be...

    How can people do h&t or left foot braking if the throttle cut off while on brakes? I can imagine only automatic transmission will have this kind of software setting.

    Not quite right. There are some Mercedes models with manual or Sequentronic.

    You're right William...

    The eGas throttle does not automatically cut the throttle when the brake is depressed. Someone is confusing the fact that PSM, when defeated by the dash switch, temporarily reactivates when the brake pedal is depressed. I can blip the throttle anytime with my toe on the brake.

    Re: It can't be...

    RC - Oh, in the US, I don't think you can have a manual (maybe on the SLK only)...
