Pseudoscience describes any belief system or methodology which tries to gain legitimacy by wearing the trappings of science, but fails to abide by the rigorous methodology and standards of evidence that are the marks of true science.
1 Flex-fuel hybrid electric and flex-fuel plug-in hybrid are two types of hybrid vehicles built with a combustion engine capable of running on gasoline, E-85, or E-100 to help drive the wheels in conjunction with the electric engine or to recharge the battery pack that powers the electric engine.
Only a fraction of the cars and trucks on the road are flex fuel vehicles: those that can run on conventional gasoline or E85 ethanol fuel. You'll learn why that number is growing, and how you can determine whether your next new car or truck -- or maybe the one you already own -- is an E85 ethanol flex-fuel vehicle.
