The 2009 Chevrolet Aveo lineup gets slightly more power and a restyled hatchback model. Chevrolet's smallest car comes as a 4-door sedan or a 4-door hatchback called the Aveo5. Sedans and Aveo5 offer LS, 1LT, and 2LT trim levels. All have a 106-hp 1.6-liter 4-cylinder engine, an increase of 3 hp from 2008. A 5-speed manual transmission is standard, and a 4-speed automatic is optional. Available safety equipment includes ABS and front-side airbags. Other available features include satellite radio, air conditioning, sunroof, power windows and door locks, remote entry, heated side view mirrors, and cruise control. GM's OnStar assistance is newly standard on all models. We have not yet tested the 2009 Aveo.
