The car has front-wheel drive with the engine located transversely at the front. The body is in the form of a hatchback (most models) and sedan.

First generation (T200, T250; 2002–2011)
The first generation was based on the T200 platform and was introduced in 2002 as the Daewoo Kalos (Greek for "beautiful"), replacing the Daewoo Lanos on the T100 platform. And in the spring of 2003, the Chevrolet Aveo was introduced at the Chicago Auto Show in the United States. The body shape was a 3- and 5-door hatchback or a 4-door sedan. The Aveo model differs from the European Kalos by a horizontal chrome strip along the radiator panel and larger dimensions.
GM unveiled a redesigned sedan at the 2005 Shanghai Auto Show, developed in collaboration with PATAC (Pan Asia Technical Automotive Center), based on the T250 platform and sold in South Korea as the Daewoo Gentra. Changes included new exterior styling, a new instrument panel, and minor equipment changes, as well as increased sound insulation. The inclusion of a radio antenna in the rear window and wind tunnel testing helped reduce the drag coefficient from 0.348 to 0.326. In 2007, the facelifted Chevrolet Aveo was unveiled at the Frankfurt Motor Show.

Aveo is a modern car and it has ABC, power steering, air conditioning, electric windows and fog lights. The base has an airbag for the driver and front passenger and 3-point seat belts for all passengers.
Second generation (T300; 2012–2020)
The second generation debuted at the Paris Motor Show in 2010. Official sales began in 2011 in the United States under the name Sonic. The car is based on the global subcompact GM Gamma II platform. The body is presented in the form of a 5-door hatchback and a 4-door sedan. The second generation Aveo was developed by the GM Korea division, and Opel engineers were engaged in developing the platform. Engineers from Australia (Holden) and the United States (Chevrolet) also made a significant contribution.
The exterior design was done by Australian designer Ondrej Koromhasz of Holden, who was sent to GM Korea from 2005 to 2007. He described his idea for the Aveo as a "four-seater motorcycle," which is reflected in the motorcycle-style headlights and instrument cluster. U.S.-spec cars have suspension tuning by Chevrolet Corvette engineers.
