I appreciate the responses thus far and for the most part they have assuaged my fears of low (for a Prius) mpg. To answer some of the questions: 1. Charging is not an option at work. We have to park pretty far away from the building. Perhaps someday there will be front-row charging stations. For my commute a BEV, PiP or Volt would be ideal. However... 2. I have driven both the Volt and the PiP. I don't want to turn this into a Volt vs. PiP vs. Gen III debate, but the PiP is $6k more than a comparable Gen III Five ($33k vs. $39k) and the Volt is another $6k on top of that ($33 vs. $45k). The $2500 (PiP) and $7500 (Volt) tax credits will not help me out based on the Form 8936 and my Form 1040 estimated taxes for 2012. We simply have too many deductions as a young family with a mortgage. 3. Regarding the "payback period", I understand what you are saying. I should have said that I am looking to see if the more expensive PiP or Volt are actually equal (or cheaper) over a 10 year period than a comparable Prius. To the best of my knowledge and ability to find data online, unless gasoline rises to >$7/gal and stays there, then the regular Prius wins over that period.
