    Default R8 V10 MANUAL vs R8 V10 R-TRONIC




    R-Tronic is the white one and the V10 manual x races is the blue one

    DAMN that V10 sounds HOT !

    Not clear why the manual is so much faster. Was the R-Tronic set in Sport mode and paddle-shifted, or left in automatic?

    When Road and Track tested them, it found the R-Tronic to be the faster of the two, I believe.

    I'd assume drivetrain loss. A robotized single clutch automatic will have quite a bit more parasitic loss than a standard manual, i.e. less power to the wheels. I'm curious what a R Tronic car puts down on a dyno compared to an equivalent traditional 6 speed car.

    The only difference is in how the clutch is actuated, so I'm curious as to why you think the R tronic has more parasitic loss than the stick.

    I assumed they were a little more in depth than that. Doesn't Audi's PCM adjust RPM and timing/fuel during the shift on robotized tranny's? If not, I retract my input.

    Well yes, but the dyno pulls are done in one gear. Shifting is irrelevant to dyno numbers.

    There shouldn't be that much difference in these transmission. I think the manual car may be modded for more top end power.
