    • Audi B9 RS4 Avant vs. 8V RS3 sedan dig and roll races

      The Audi RS3 may be positioned beneath the RS4 and RS5 in the Audi hierarchy but it is the choice if you are serious about performance. Yes, the 2.9 liter EA839 twin turbo V6 in the RS4 larger and more powerful but the 2.5 TFSI is the better powerplant for tuning.


      Why? It is lighter, has an easy path to a big single turbo upgrade, and it features both port and direct-injection fueling systems. Plus it is mated to a dual clutch transmission instead of an automatic.

      Put all of that in a chassis roughly 400 pounds lighter and the RS4 is forever chasing its sibling. The 2.5 TFSI also has a huge aftermarket head start. It's no comparison really.

      The only time you can compare them is when stock and Audi obviously keeps the RS3 just slightly behind to maintain the artificial hierarchy.

      The video reflects this but also the roll race is done poorly (yet again) by waiting on the car to downshift instead of just being in the right gear and right rpm to begin with. This usually favors a bigger engine as well.

      Regardless, the RS3 is already running 9's. It will be in the 8's before the B9 RS4 or RS5 gets into the 9's.

        IMO, waiting for downshift is the proper way for a rolling race because downshift and spool up is part of power delivery. The best would be start from the highest gear possible and see what gearbox can do from there.

        Putting in the right gear to start a rolling race is very wrong. It makes smaller engine quicker and faster than they really are. And makes a false perception that a smaller high boosted car is always faster on the road. In reality, they're very dumb and slow.

        whaaa??? Does anyone know anyone that roll races that way? I have never heard of a starting a roll race from the highest gear...

        I know for sure all the roll races I've watched are done by being in the right gear for maximum power and rpm at the agreed to speed...e.g. 40mph...

        For $#@!'s sake it's why people have to re-do roll races because they were in the wrong gear for the 40 roll

        This makes no sense whatsoever.

        So if the cars were manual you would have them in the wrong gear and wrong rpm? Because downshifting is part of the power delivery?

        Downshifting in these is part of the shift logic not power delivery.

        How? The idea is to see what car is faster from a roll not who programmed a fancier kickdown.

        Um, yeah, smaller motors needs to worry more about what gear they are in than bigger motors with more torque.

        Your post zero logical sense.

        I'm just going by what the cars have done. The RS3 is way, way ahead.
