Scion iA Real Gas Mileage: Pros
YearComment
2016 The Scion iA's light weight also pays fuel economy dividends. EPA ratings of 31/41 with the manual transmission and 33/42 with the automatic (both with six ratios) are best-in-class, with one partial exception. With a turbocharged 1.0-liter three-cylinder engine the Ford Fiesta manages 31/43, but this engine is a $1,000 option and is available only with a five-speed manual transmission. With its standard 1.6-liter engine, the Fiesta manages only 28/36 with a manual and 27/37 with an automatic. In my real-world suburban driving the trip computer often reported averages over 40 mpg, though driving the car like the typical American sunk the average all the way into the mid-30s. On a 70-mph highway with the temperature right at freezing (not ideal) the trip computer reported a two-way average of 44 mpg. Driven with a very light foot, the Fiesta EcoBoost (with the turbocharged triple) can achieve a suburban average in the low 50s, and averages in the mid-40s aren't too difficult. But push the Fiesta and the average will fall into the 30s and even the upper 20s. Fuel economy does tend to vary more with turbocharged engines, as the turbo serves to force more air (and with it more fuel) into the cylinders when this is called for. Most drivers will observe real-world fuel economy as good or better in the Scion iA. Then there's the Mazda3. Though larger and considerably more powerful than the iA, it achieves EPA ratings that are nearly as good, 29/41 with a manual transmission and 30/41 with an automatic. Step up to the truly quick Mazda3 s, with an engine a full liter larger than the iA's (2.5 vs. 1.5 liters), and with an automatic the EPA ratings remain too close for comfort, 28/39. Once the figures get to this level, you tend to give up more in performance than you gain in fuel economy. see full Scion iA review
