Production Years and Model Codes
The second generation of the Chevrolet Aveo, known internally as the T300, was produced from 2011 to 2020. In North America, the model was sold under the name Chevrolet Sonic, while in Europe, Asia, and other regions, it retained the Aveo name.
The car was developed as a global model, so it had different body styles:
- Sedan (T304) – The most popular version, especially in the USA and Russia.
- Hatchback (T307) – A 5-door variant with a dynamic design.
- Hatchback RS – A sporty version with aggressive exterior styling (not available in all countries).
Model Overview
Design and Platform
The Aveo II (Sonic) was designed under the guidance of GM Korea (formerly Daewoo) and Chevrolet's American division. The car featured a more expressive and modern appearance compared to the first generation. The radiator grille followed Chevrolet's "dual-tier" design language, while the sleek body lines and compact dimensions made it one of the most stylish cars in the B-segment.
The Gamma II platform, developed by General Motors in collaboration with Opel, provided a rigid body structure and good handling. The suspension was typical for this class: MacPherson struts at the front and a semi-independent torsion beam at the rear.

Gasoline engines:
