Many of us are familiar with www.fueleconomy.gov that has been a ready resource to compare cars. But it was limited to four car comparisons. Several years ago, I stumbled across the "Test Car Database" at EPA.gov which is very technical. But there is a new resource (to me): Fuel Economy Web Services It provides similar data but across the fleet. Not as technical as the "Test Car Database," is provides an easy way to do fleet-wide comparisons. It also looks to be fairly current, March 2016 updates. Bob Wilson
