Mazda CX-3 Real Gas Mileage: Pros
Year	Comment
2016	You might expect a small, light vehicle to go farther on a gallon of gas, and here as well the Mazda CX-3 doesn't disappoint. With front-wheel drive, the CX-3 earns EPA ratings of 29 MPG city, 35 MPG highway. The city rating is one MPG higher than the HR-V's, while the highway rating is a tie. When fitted with all-wheel drive (AWD), both models still manage 27/32. The JUKE isn't far behind: 28/32 with FWD and 26/31 with AWD. A Fiat 500X, though not as quick as the CX-3 and fitted with a nine-speed automatic transmission, lags well behind in city driving with 21/30. In my real-world suburban driving I had little trouble exceeding the EPA city figure, with trip computer averages usually around 30 and as high as 36. The HR-V's trip computer reported numbers two or three MPG higher in the suburbs, but this could be because it has an Eco mode that facilitates hypermiling. Even in its regular mode the Honda doesn't encourage inefficient driving the way the Mazda does. On a 70-MPH highway the trip computers in both vehicles reported averages around 33 or 34, a bit better than their EPA ratings. see full Mazda CX-3 review

2008	4dr Sedan 110-horsepower 1.6L I4 5-speed manual FWD	From a 17mpg average Chevy truck to NEVER getting less than 29mpg city, need I say more? Well okay, how about 37mpg on a freeway run. I have only got 13000 miles on the vehicle, and can imagine the fuel economy will improve still more. see full Kia Rio review
