General Motors Corp. will soon start selling a car in Brazil that will run on either gasoline, alcohol or natural gas.
The company will offer the multifuel technology in one of the existing models it makes in South America's largest country.
Sales are expected to begin next month, but GM declined to offer more details.
GM, Fiat SpA and Volkswagen last year began selling Brazilian "flex-fuel" cars that run on either alcohol or gasoline, but GM's new car will be the first to come with the natural gas option.
Brazilian car users have been installing natural gas conversion kits for years so their cars can run on natural gas in addition to either alcohol or gas.
But the feature has never before been offered as an option from the factory by car makers.
Automakers sold 150,000 flex-fuel cars in Brazil from January through July, representing 18 per cent of total new car sales.
