GM's largest overseas subsidiary is General Motors do Brasil, which started producing flexible-fuel vehicles since its inception in the Brazilian market in 2003. Like other Brazilian flex-fuel vehicles, GM's flex fuel cars and light-duty trucks are optimized to run on any mix of E20-E25 gasoline and up to 100% hydrous ethanol fuel (E100). GM launched its first flex fuel in June 2003, the Chevrolet Corsa 1.8 FlexPower, just two months after the first flex car was launched by another Brazilian carmaker
GM do Brasil also introduced the MultiPower engine in August 2004 which was capable of using natural gas (CNG), ethanol and gasoline (E20-E25 blend) as fuel, and it was used in the multifuel Chevrolet Astra 2.0 model 2005, aimed at the local taxi cab market. The Brazilian GM Powertrain unit also developed the EconoFlex technology, used for the first time in the Chevrolet Prisma 1.4, which allows the flex fuel engine to maximize fuel economy and power.
Due to the success and rapid consumer acceptance of the flex versions, GM sold 192,613 flex vehicles and 135,636 gasoline-powered automobiles in 2005, jumping to 501,681 flex-fuel vehicles while only 949 cars and 6,834 light trucks powered by gasoline were sold in 2007, and reaching new car sales of 535.454 flex fuels in 2008, representing 97 percent of all cars and light duty trucks sold in that year.
