The Aveo returns in sedan and hatchback form for 2009. Chevy has made some minor adjustments to option packages and interior materials, but there are no big, notable changes. Aveo sedans gained a number of interior enhancements for 2008, which included higher-quality materials, wood-grain and metallic trim, a driver's armrest, and additional storage space. The hatchback did not receive these changes.

The Aveo has been praised for its economical entry price, thoughtfully laid out ergonomics, and a spacious cabin. Unfortunately, the sub-compact's antiquated powerplant does not offer much in the way of power or fuel economy. Many reviewers have also complained about the manual transmission's awkward feel. The hatchback's interior has not benefited from recent aesthetic updates, and it has more of an economy-car feel than the sedan. The Aveo also faces stiff competition from some newer subcompact offerings courtesy of marques like Hyundai, Honda, Nissan, Scion, and Toyota, as this segment continues to expand with rising fuel prices.

All Aveo trims are powered by a modest 1.6-liter four-cylinder engine, which generates 103 horsepower and 107 pound-feet of torque. A five-speed manual is the standard transmission, but an optional four-speed automatic is also available. EPA estimates are 23/33 mpg with the manual gearbox and 23/31 with the automatic. Despite the underpowered engine and less-than-stellar fuel efficiency, the Aveo has proven more than adequate for daily urban commutes. The suspension is tuned on the softer side, and the steering is responsive.

The Aveo subcompact is available in an entry-level LS trim and two better-equipped LT levels, all in sedan and hatchback body styles. The Aveo5 designation is used for the hatchbacks. The entry-level LS trim is sparsely equipped, with manual accessories, steel wheels, and a simple four-speaker AM/FM radio. The LT trim comes equipped with 15-inch alloy wheels, air-conditioning, cruise control, a sunroof, power windows, keyless entry, and a CD/MP3 player. Options at the LT level include leatherette upholstery, an in-dash CD changer, and steering-wheel-mounted audio controls. While antilock brakes are optional on all trims, side curtain airbags are not available. Front-seat side airbags are standard on all trims.
