 As other Brazilian flex-fuel vehicles, these models run on any blend of hydrous ethanol (E100) and E20-E25 gasoline.Initially, and in order to test the market preferences, the carmaker decided to produce a limited share of the vehicles with flex-fuel engines, 33 percent of the Civic production and 28 percent of the Fit models.Also, the sale price for the flex-fuel version was higher than the respective gasoline versions, around US$1,000 premium for the Civic, and US$650 for the Fit, despite the fact that all other flex-fuel vehicles sold in Brazil had the same tag price as their gasoline versions.
