Scion iQ Real Gas Mileage: Pros
YearBody/PowertrainComment
2014 2dr Hatch 94-horsepower 1.3L I4
CVT FWD		 I pretty much have been ignoring the ECO light lately just to see what my MPG is, and I've been getting an average of 35. Pretty close to the 36/37. see full Scion iQ review
2013 2dr Hatch 94-horsepower 1.3L I4
CVT FWD		 So far this car has lived up to the MPG ratings of 36 city/37 hwy. You have to drive it with a light foot and try to keep the "eco" light on as much as possible to achieve that mpg rating. If you're too heavy on the gas, it'll quickly drop to around 30/31. see full Scion iQ review

smart fortwo Real Gas Mileage: Pros
YearBody/PowertrainComment
2013 2dr Hatch 70-horsepower 1.0L I3
5-speed automated manual RWD		 good mpg car for the price and simplicity of a lightweight car with only a gas engine. Even if you only get the EPA combined estimate of 36 it is good mpg and competes well in its class. But many smart drivers get much higher. My first 10k miles averaged 45 mpg, based on miles per gallon measured at each fill up, mix of city and freeway. Recently I had 48 mpg and 51 mpg tanks on my usual route. Check Fuelly.com for a realistic picture of mpg to expect. Low 40s mpg is most common. see full smart fortwo review

2009 2dr Hatch 70-horsepower 1.0L I3
