vortex generators - Toyota Yaris Forums

With my bro's Prius C, I get a minimum of 65 mpg (more usually in the 70's) in the city. I never drove it on the freeway yet, but when we took it out the other day, and with my bro driving (not as good at hypermiling as me), and with the AC on, he got 61 mpg over the course of around 60 miles. It's a pretty good car. Not as much space as my Yaris, definitely slower, and the HU is harder to work with, requiring you to be stationary to Bluetooth pair or enter a destination in the navi.

I had VG's on my sedan before set to the Vortekz default spacing and angles. When ever my rear window would fog up, a few minutes of driving on the freeway would create triangular clearings on the top of the window and eventually would clear the entire window. I took the VG's off (since too many people wanted to race my car and I was getting tired of that), and now I have to use the rear defroster to clear the window, so I know they definitely worked in regards to changing the air flow. I only saw .xx mpg improvement with them tho.
