you can still dyno an all-wheel drive car on a 2 roller dyno though, just remove the drive shaft and now its a 2 wheel drive car.
That's what I assumed they'd have to do. I wonder if dynoing an AWD car with the drive shaft removed is as accurate as testing one with four rollers and all wheels driving. I bet a two-roller machine would be more generous, but not much. Maybe a couple ponys.
