Yaris: How Many RPMs @ 70mph?

[eco]

I bet your rpm is alot higher then its supposed to be,in 1st 2nd and 3rd,untill you get up to speed,this is where the weight of the rim bennifits your car,more rotating mass thats already spinning,this gives the car a high forward momentum,which helps ease engine load,the faster your going the better(for this effect,be safe ofcourse).But check your rpm going uphill

Well the rpm is going to be a bit lower for the same speed across the board, but it does take more effort to get goin.

I've noticed that my MPG figures remain the same (31-33) whether i'm going 80+ or cruising 55... before cruising 55 would get me 35-36mpg.

Going off the post here that noted there is a 6% difference, its just an educated guess :)
