I had a 2011 Prius package 2 for almost a year and traded it in and paid the difference for a 2012 Prius package 3. The reason for this was for a couple reasons, one was I noticed the standard features on the 2012 were a lot more compared to 2011 and felt short changed since I really wanted bluetooth to be standard on package 2 (the aftermarket one I got sucks) and I really wanted a USB port. Also I regretting the color I got and wanted black. So I decided to get a package 3 2012 to get the added GPS, back camera and extra smart key doors in addition to the built in bluetooth and USB port. I noticed the MPG i am getting compared to my 2011 is a little lower on average after filling up 3 or 4 times. I would average around 44-45.5 pretty consistently with my 2011. I am averaging now 43.7 mpg with my second fill up being my worst ever mpg at 42.6. This tank I am probably getting around 43.5 so far with 300 miles. Is there anyone out there that traded a Gen III Prius to Gen III 2012? If so, how is your MPG?
