Brazil launched the Ethanol vehicle program in 1979. The production raised to more than 80% and declined to low values due to Ethanol shortage problems. In 2000 E100 usage was fostered again and Delphi developed the Multifuel® System where the vehicle could use fuels with any ethanol percentage. The production of Multifuel vehicles reached 35% and is increasing. Besides that Brazil is experiencing an abundance of CNG. CNG converted vehicles normally use a second ECM, however the performance isn't optimal. In 2004 Delphi developed a MultiFuel-CNG system with one ECM controlling both fuels with little power loss and excellent driveability and fuel consumption.
