I dont know why I have not seen this discussion before. I have already seen an MPG analysis on mudflaps. MUDFLAPS!! The owners that have added the EV button have noticed an noticeable increase in gas economy? Please comment and include numbers.
I don't have numbers, but I do have a couple of pictures of my display of trips with and without EV usage. It makes a pretty significant difference in my first 5 minutes, but it's somewhat offset in the second 5. I haven't tracked it close enough to state that it's overall worth it though. For me, it's as much of a geek mod as anything else Plus, it's great for conversation amongst other Prius owners. The pics are in my phone right now, so I'll try to post the photos later tonight.
