2012 Toyota Prius Plug-in Hatchback 4dr Hatchback (1.8L 4cyl gas/electric hybrid CVT)
Real world experience with the Prius Plug in.
 I have a 4 mile work commute and often drive 15 miles to Portland on weekends, so my driving is a mix of city and some hwy. Late this summer I averaged 105 MPG across three fill ups. I have seen my milage down to 65 MPG city during the winter with lots of heater and defroster use. On an extended trip accross the state, I averaged 52 MPG hwy - just as advertised.I have two 2012 Prius Plug in's and have spent $1200 less on gasoline during the first year than we did owning two Corollas so the savings is very real.Our electricity bill has only gone up $15 per month charging 2 cars, though some savings is achieved there with our Solar panels. Figure about 25-30 cents to charge at PDX rates.
