Mazda Flex Fuel Vehicles
Mazda's U.S. flex-fuel presence is entirely a product of its historical partnership with Ford. Only two Mazda vehicles were ever factory FFVs in the United States, and both were badge-engineered Fords. The B-Series pickup (a rebadged Ford Ranger) carried the 3.0L Vulcan V6 FFV from 1999 through 2003, and the Tribute compact SUV (a rebadged Ford Escape) offered the 3.0L Duratec V6 FFV from 2009 through 2011.
No Mazda-developed vehicle — not the Mazda3, Mazda6, CX-5, CX-9, CX-30, CX-50, or MX-5 Miata — has ever been a factory flex-fuel vehicle in the U.S. Online references to a "Mazda6 FFV" are aftermarket-conversion content, not factory designations. Mazda's U.S. FFV installed base is small, aging, and mechanically identical to the Ford donors.

Mazda-specific E85 tips
Treat Mazda FFVs as Ford FFVs for service.
Parts, diagnostics, and fuel-system components are shared with the Ranger and Escape, so independent shops familiar with Ford products will have no trouble supporting either vehicle.
No Mazda sedan or crossover is an FFV.
If you drive a Mazda3, Mazda6, CX-5, or any newer Mazda, you do not have factory flex-fuel capability regardless of badging claims.
Tribute FFV is the 3.0L V6 only.
Four-cylinder Tributes and the hybrid Tribute are not FFVs. Confirm the engine before filling with E85.
B-Series FFV is Vulcan-specific.
Only the 3.0L Vulcan V6 B3000 is a factory FFV; the 2.3L I4 B2300 and the 4.0L V6 B4000 are not.
