Once the battery is depleted (after ~15 miles) it will operate in traditional hybrid mode, the battery will not be recharged more than needed for hybrid operation. It would be a net energy loss if the gas engine were to recharge the battery and then the battery were to drive the wheels (energy into/out of battery is not 100% efficient) - Patrick Thu, 29 Sep 2011 11:36:44 +0100 http://www.ecogeek.org/automobiles/3594-toyota-unveils-the-plug-in-prius#comment-44585 Once the battery is depleted and the engine kicks in, does the engine re-charge the battery as you drive? If so, once the battery is recharge does the engine turn off and return to battery power? - Robert Thu, 22 Sep 2011 01:56:07 +0100 http://www.ecogeek.org/automobiles/3594-toyota-unveils-the-plug-in-prius#comment-44573 To be more clear, the 15 mile range is for electric-only drive. Thanks for catching that. - P Proefrock Tue, 20 Sep 2011 13:06:34 +0100 http://www.ecogeek.org/automobiles/3594-toyota-unveils-the-plug-in-prius#comment-44568 The article says the range is 15miles at 64 miles an hour. This is either vapid journalism or poor engineering. - Simon Tue, 20 Sep 2011 00:52:08 +0100 http://www.ecogeek.org/automobiles/3594-toyota-unveils-the-plug-in-prius#comment-44565 Very exciting to see manufacturer's heading this direction, can't wait to hear the reviews! Toyota is doing amazing things - Recycle Gal Mon, 19 Sep 2011 14:24:59 +0100
