Review: 2012 Mazda 3i Grand Touring 4-Door

Saving With Shellie

The EPA Fuel Economy Estimates for the Mazda 3i Grand Touring are 28 MPG for city driving and 40 MPG for highway driving. The one thing I loved most about this was the blind spot monitoring system. I drove the Mazda 3i Grand Touring from Austin to Dallas and back. I made the entire trip on a single tank of gas.
