have been produced in Fiat Automóveis factory in Betim since 1976, plus 232,807 units in the Fiat Argentina plant of Córdoba. The original factory, located in the city of Belo Horizonte, cost $250 million to build. The state of Minas Gerais had a 10–20% stake in the company and also provided special economic benefits to Fiat. Launched in July 1979, the 147 was the first mass-produced car that ran on ethanol as fuel instead of petrol. The performance slightly increased and fuel consumption was 30% higher but the cost of the alcohol was a quarter of the gasoline because, at that time, petrol had become expensive as a consequence of the 1979 oil crisis. This version was nicknamed cachacinha (little cachaça) because it had the scent of that Brazilian drink. In October 1984 Fiat Automóveis introduced the Fiat Uno, which continued on sale until the end of 2013 as the renamed Fiat Mille, resulting in total production of 3.6 million vehicles. Production of the Fiat Palio world car began in 1996. After the successful 2003 introduction of flexible-fuel vehicles in the Brazilian market, Fiat Automóveis launched its first flex model in March 2004, the Fiat Palio, followed by the Siena and Palio Weekend. Fiat sold 665,514 vehicles in Brazil in 2008, allowing the carmaker to continue as the market leader for seven years in a row. Flex fuel automobiles represented almost 100 percent of the car sales in 2008, and 92 percent of all light-duty trucks sold. In 2006 Fiat introduced the Fiat Siena Tetra fuel, a four-fuel car developed under Magneti Marelli of Fiat Brazil. This automobile can run as a flex-fuel on 100% ethanol (E100); or on E20-E25 blend, Brazil's normal ethanol gasoline blend; on pure gasoline (though no longer available in Brazil since 1993, it is still used in neighboring countries); or just on natural gas (CNG). The Siena Tetrafuel was engineered to switch from any gasoline-ethanol blend to CNG automatically, depending on the power required by road conditions. Fiat Argentina Fiat has been present in Argentina since the beginning of the 20th century. There was a Fiat manufacturing plant in Córdoba at least as far back as 1954 when Fiat entered into a joint venture with two local companies to manufacture tractors. The company was known as Fiat-Concord until 1980. In 1959 the construction of a car plant in Caseros was approved, and 1960 saw the
