The Prius merely exits EV mode and goes back to hybrid mode, meaning it pollutes under hard acceleration and doesn't pollute under gentle acceleration, when coasting, when stopped at a stoplight and when decelerating. Like I said, it seems the short range on EV mode is more to protect the battery than because that's all the charge there is.

If we count cruising while already at speed, the Prius can easily do a number of miles without using gasoline when the battery is topped off. The 2 kilometer limit we tested from a dead stop.
