Iveco tried a similar setup with ethanol instead of gasoline some years ago, and MWM (currently owned by Navistar) has developed dual-fuel versions of the 229-series engines (at least in 4-cyl and 6-cyl versions) which relied on mechanical direct injection for both the regular Diesel fuel and the ethanol. Apart from some tractors, Ford has used it in some trucks meant to operate at sugarcane plantations.

Just to remind, it's a flexfuel, not a dedicated-ethanol, even though the dedicated-ethanol cars in Brazil retained a small auxiliary gasoline tank for cold starting. I'm just not sure if the March retained this auxiliary tank in later versions or if it now resorts to a heated fuel rail like the Sentra.
