 My car is suppose to get 23/32 MPG but no matter how I drive, Eco, Normal or Sport, baby driving...coasting to red lights in city and doing 75 hwy, I consistently come in 4 MPG less both city & hwy.  I have tested the computer read by the old fashioned way of spending down the fuel and then filling back up, tracking the mileage.  I have done Octane additives at the suggestion of the Hyundai service advisor.  I took in to get the car's computer system checked.  They just want to blow it off as did the Hyundai America customer service.  When I read reviews on the Turbo 2.0 Sport limited, I see every so often drivers mentioning their mileage at what I am suppose to get yet am not. I figure at $2.50 per gallon this will cost me about $300 a year!  Not happy and not done complaining. Now, for the rest of the car, it is awesome for the money.  I have used numerous times all the tech stuff on this Ultimate package that comes on the Sport Turbo limited.  Very impressive.  I hear complaints on the pick up but I am telling you that if you throw into tiptronic, you will fly!  The smart car technology on cruise is awesome, cross traffic control is incredible, back up cam with sonar, excellent, BSD and BSD oncoming warning is spot on, forward crash avoidance works like advertised!
