Chevrolet Aveo / Sonic (2011-2020): How to Remove the Bumpers

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.

Depending on the market, different powertrains were offered:

Gasoline engines:

  • 1.4L (100 HP) – The base engine for Europe and Russia.
  • 1.6L (115–121 HP) – A more powerful option, available with a 6-speed automatic.
  • 1.8L (138 HP) – Offered in the USA and some Asian markets.
  • 1.4 Turbo (138–140 HP) – A turbocharged version for the Sonic RS (USA) and some European models.

Diesel engines (Europe only):

  • 1.3L (75–95 HP) – An economical option from Fiat.
  • 1.7L (125 HP) – A more powerful diesel.
