GM Inside News Forum - Fuel Economy Guide

» Fuel Economy Guide

About:

Welcome to GMI’s newest Guide. All fuel economy figures are from the EPA unless otherwise stated. Engines/MPG figures that are highlighted in yellow indicate an E85 model, and vehicles with their name in green indicate that they are in GM’s “30 MPG and Up Club.”  GMI is in the process of updating the FE Guide to the new 2008 EPA ratings.  We are currently at the Chevrolet Silverado working down the list.
