 I drive a total of 60 miles a day to work and back home. I travel both on highway and city. I use the ECO feature when dealing with traffic and have on the average (depending on where I buy my gas) get 34mpg. I have noticed with lower grade stations, the perfomance is less. The pickup while using ECO is a bit regulated but with a quick click, you can turn it off and get the punch you need to pull quickly ahead.I replaced this car with a 2007 PT Cruiser which had horrible gas milage. I find the instrument panel great with the RIO SX model and love the rear screen view due to the limited viewing of the rear window.I would definitely recommend the Rio to other buyers. It is fun to drive!
