Friends: 0 | ..it seems more like a marketing gimmick than serving any useful purpose. As long as there is enough battery power, the Prius is automatically powered solely by the battery at low driving speeds 20mph+/- which is the same threshold when manually engaging the EV button...so what's the point? |

Friends: 0 | You can delay the engine starting so silently leave an area if noise is an issue. |

Friends: 0 | When you are in EV mode you can push a little harder on the pedal than you could in non-EV mode. If you aren't in EV mode and you get the Hybrid indicator bar beyond halfway the ICE will kick in. In EV mode you can push beyond halfway and accelerate a little quicker provided your battery charge is sufficient. |

Friends: 1 | Buyers in North America wanted it. So much so they were adding the switch for it to their Gen II Prius. The function(not a feature) is already built into the operating system and was available to the rest of the world. No gimmick it's just a manual switch to allow fixed ev mode. You can also switch to eco and pwr and the "null" switch for normal. No big deal really and will be rarely used by most people. |

Friends: 6 | For the average driver interested in average (for the Prius) fuel economy, there's not too much point in it, other than perhaps to show off to friends how quiet the car is tooling around the parking lot. For some of us obsessed with fuel economy, it can make a significant difference when used properly in the right driving conditions. See this for more. |

Friends: 33 | I use EV to keep the ICE off while I get away from my house and my neighbour's bedroom window when leaving for work at 6AM. Also to move quietly through carparks, and my engine never runs in my garage. I don't use EV often but I like having it. |

Friends: 0 | I have tried several times to activate the EV mode by pushing the button. Each and every time, I accelerate very slowly and at approx. 12mph it flashes a window that says the EV mode has deactivated. btw, there have been 7 battery bars each time. What's up with that? |

Friends: 0 | I might be wrong but I the reason it's there is because the 2010 was designed to be a PHEV (Plug-in Hybrid Electric Vehicle) even though they delayed the launch of that functionality. As I recall there are some fleet ones that are equipped as PHEV's being tested around the world. It makes perfect sense to have this button on a plug-in. |

Friends: 0 | I'd call it the "impress your non-hybrid owning friends button" as I think it's biggest draw is pressing it at the airport parking lot as you drive away to impress the friend who's never ridden in a Prius before. Functionally, it really has little value. From a marketing standpoint hey 3 modes are better than two. |
