Rolling roads and autoboxes.
Discussion
Something I've been wondering...
On a rolling road, you stick the car in gear, take an RPM measurement at a known speed, then run it up through the revs, let it coast back down, and these various things end up giving you curves for power and torque vs. engine speed, right?
So what happens if you rock up with a bog-standard autobox, no tiptronic, in fact no way of holding it in a specific gear at all? Can you get a sensible dyno graph for an auto?
