The same as every Prius we've tested this year, meaning there's very little technique involved in launching it. Mash the throttle and hold it down. I did notice battery charge diminishing, but this didn't seem to affect acceleration.
Same unusual and awkward brake feel as every Prius we've tested. Same average stopping distance, too.
Slalom: The key to any dynamic maneuver in the Prius is to stay clear of its aggressive stability control by using slow, smooth inputs. Skid pad: Stability control overmanages the skid pad with constant interruption. There's no avoiding it here.
