    Okay I just read an article in Australian Motorcyle News mag. about fly by wire and how some teams are trying to use it in MotoGP. What I did not realise is exactly it's purpose in F1 (yes I know head in the sand ... ;)), and that is to ensure that a 25% movement with the throttlw will result in a 25% rear wheel torque increase.

    I thought they used the throttle input for other things, etc. But ofcourse this is what makes these screamer engines so easy to drive, because the fly by wire throttle takes the skill out of throttle control.

    Most of us here have probably raced cars where we have modified the engines and chucked in some wild cams and ended up with a really peaky engine ... and this makes throttle control so much more important.

    Just imagine how much SLOWER F1 cars would be without the fly by wire throttle. Quite simply I reacon we would be down about 200 hp (easily) because we now have motor engineers only worrying about maximum power and not having to think about linear torque curve, etc. because the computer will make it appear linear via throttle control.

    This is surely got to be the easiest change to the rules, ie. engine must have throttle 100% controlled by the drivers foot. We would wind back to before the turbo days instantly, or atleast early turbo days.

    Very clever technology but it has removed way to much skill from both driver and engineer!

    Your thoughts?

    Okay, so maybe I'm a bit out of date here, but I still think of F1 as a manufacturer's race: So I tend to oppose banning any technology applicable to road cars.

    Fly-by-wire throttles are crowding the starting gate on road cars. (I think the M5 already uses it). Let the high-paid drivers work the bugs out of it before the rest of us have to live with it daily.

    Want to slow down F1 cars? Pure carbon fiber rotors need to be too hot to work on road cars. But I'm not sure how you'd word a ban without also excluding the carbon-ceramic technologies that do work on the streets. (Maybe a homologation standard -- you can only use brake rotor materials from your production cars? But where would that leave Williams, Sauber, BAR, etc?)

    But if the proposed rules changes go through, F1 will become just another spec race series, so it probably doesn't matter anyway.

    The F1 engines move both the length of the velocity stack (on an RPM by RPM basis) and the opening of the throttle (on RPM by RPM basis) to smooth out peaks and diviots in the TQ curve as RPM rise. Traction control is a simple side effect of this kind of airflow management.
