What is Ecomodding?
Welcome to EcoModder.com, an automotive community where performance is judged by fuel economy rather than power and speed. EcoModders employ a combination of vehicle mods, driving techniques, and common sense to squeeze every penny out of the pumps. Reasons for becoming a member range from the economical to the ecological. More info about where EcoModding came from.
