Ford has been mired in a fuel economy lawsuit alleging that the automaker knowingly overstated its fuel economy estimates for the 2017-2019 Ford F-150 and the 2019 Ford Ranger for some time now. But now, a new yet similar fuel economy lawsuit has been filed in the U.S. District Court for the Eastern District of Michigan: Ceremello, et al., v. Ford Motor Company which alleges 2019-2020 Ford Ranger and 2018-2020 Ford F-150 models were sold with inaccurate fuel economy ratings listed on the window stickers.
More specifically, the lawsuit claims that Ford cheated on fuel economy testing, then advertised and sold the trucks with the wrong fuel economy estimates. “Over a million Ford truck owners are now driving vehicles that will cost them thousands of dollars more to own or lease than they anticipated. Because of Ford’s deception, all purchasers and lessees of these vehicles paid more for these vehicles than they are actually worth,” the lawsuit says.
The suit claims that Ford was able to cheat its fuel economy numbers by manipulating coastdown testing, which measures rolling resistance and drag on a dynamometer. Those numbers are then used by automakers to to determine the metrics used to estimate fuel economy.
Additionally, the lawsuit claims that Ford miscalculated road load, which is the force that is imparted on a vehicle while driving at a constant speed over a smooth, level surface from sources such as tire-rolling resistance, driveline losses, and aerodynamic drag.
The lawsuit uses a 2018 Ford F-150 equipped with Ford’s 2.7L EcoBoost V6 as an example. That particular truck has a fuel economy rating of 20 miles-per-gallon city, 26 highway, and 22 combined. The suit alleges that the actual fuel economy of this truck is 17.7 mpg in the city and 22.7 on the highway, which is a pretty big difference.
Finally, the new suit claims that Ford intentionally manipulated fuel economy ratings in an effort to beat the competition and sell more trucks, as well as earn more credits under U.S. CAFE environmental regulations.
