The TSX has a pretty unobtrusive MPG meter in the center of the dash.
...between the tach and speedo. (no pics available -- tried
)
The info system displays a variety of items, but I generally keep it on instant FE and cumulative tank FE for the 2 panels. The "bar graph" is a great feedback feature for anyone that drives the car (usually the Wife).
It lately showed the BIG difference in FE between cruising at 65 vs. 70.
The "Lame" feedback award goes to the Crown Vic LX -- A series of bars can be displayed to show "Fuel Consumption" -- no frame of reference, just a series of bars that go up and down. The top bar is 20+ mpg, maybe???
The Prius definitely has it. BMW used to have an analog gauge if I remember right -- may still unless i-drive drove it out.
