Improving mpg above 65mph - Toyota Yaris Forums

Uber_Otter · 03-07-2011, 03:26 PM

I have a 06 scion Xa. On the highway I get 40mpg at 64mph, at 75-80 mph it drops to 30-32mpg. Huge difference, I need to get that 10mpg back. In Dallas the Tollway speeds are 70 posted and 75-80 in real traffic. Im looking at making vortex generators to clean up the underside first, then the back. I will be making clear turbulator tape to use to smooth out the air before door gaps, on the a pillars and around the mirrors.
Let me know if you guys have any suggestions. I will be taking pictures and letting you know what I find out.
