My guess is that you're experiencing turbo lag. The turbo spins up at 1450 rpm so until then it's pretty gutless. But, I don't know the logic that goes into the electric side of the hybrid regarding when, under what conditions, and for how long it engages. But, if for some reason it doesn't engage (due to an issue or by design), you will experience turbo lag.
