Hi,

I can tell that the Echo and the xA are very similar:

I had to take it off for the winter -- too much stuff would have gotten stuck up on top. Do you have pictures of the front grill area? I have found that sealing up and smoothing the nose of the car is at least 2X more effective than mods on any of the other areas of the aerodynamics.

Scion xA aero mods

I tried covering the holes in the radiator cowling, between the bumper and the radiator, and I found that it added drag -- though I think if you close down the front grills enough, you can see some big improvements. (See the latest grill block at the end of the thread.)

I think the Echo has one big advantage over the xA: the wheel openings are much tighter to the tires, I think.
