The 2014 Impala is so completely different from its predecessor that from this point forward let’s agree those previous versions did not even exist. The new Impala carries an air of sophistication, but not snobbiness, with a comfortable modern interior and clean contemporary styling. The 2014 Impala comes in three engine options: 2.5L 4-cylinder, 2.4L 4-cylinder with eAssist (GM’s mild hybrid system) and the 3.6L V6, which is what was powering the car we tested. The eAssist model delivers 35 MPG on the highway and 29 MPG combined, the tops in this class. It even beats the Audi A8 TDI and easily bests the Ford and Chrysler competitors.
