Introduced as a low-cost subcompact car to the United States in 2004, The Chevrolet Aveo replaced the Metro as the brand's leading economy vehicle. The Aveo was sourced to North America through a partnership with South Korean automaker Daewoo. Offered as a five-passenger car, the 2004 Chevrolet Aveo was sold as a sedan as well as a hatchback. Propelling the 2004 Aveo was a 16-valve, 1.6-liter four-cylinder engine. Generating 103 horsepower and 107 pound-feet of torque, the engine delivered combined city/highway fuel economy of 30 miles per gallon. A five-speed manual or a four-speed automatic transmission could be paired with the 1.6-liter powerplant. Tilt steering, AM/FM stereo and dual front cupholders came on the base 2004 Chevrolet Aveo.
With improved features, the Aveo LS included power windows, CD player, air conditioning and remote keyless entry. In 2006, side airbags became standard on all trim levels and the suspension was tuned to provide more responsiveness. The Chevrolet Aveo received an extensive retooling for the 2007 model year. Slightly larger but still subcompact in nature, the 2007 Chevrolet Aveo was sportier looking than the previous year's model. In 2009, a number of standard add-ons became standard on the Chevrolet economy car including GM Oil Life monitoring system and OnStar.
The Ecotec brand four-cylinder engine was bumped up to 106 horsepower in 2009 and was once again enhanced to 108 the following year. Despite the increase in engine power, the Chevrolet Aveo never achieved a substantially popular reputation in North America. While the Aveo name remained in use some global markets, the redesigned 2012 Chevrolet subcompact car was rebranded the Sonic in North America.
The compact 2010 Chevrolet Aveo is available as a four-door sedan or a five-door hatchback, and both body styles are powered by a very efficient 1.6L four-cylinder engine which gets over 30 mpg on the highway.
