The Daewoo Lanos was developed in collaboration with reputable European engineering firms and shared its platform with the Daewoo Nubira and Daewoo Espero (in terms of powertrain and some chassis components, though not directly shared).

Design Origins:

The exterior styling was handled by Italdesign Giugiaro, contributing to its distinctive and appealing look for its class.

Production Period:

1997 - 2002 (for the T100 generation).

Manufacturing Locations:

Primarily South Korea (Busan), but also produced under license in other countries like Poland (FSO) and Egypt.

Acquisition Impact:

Following the collapse of the Daewoo Group, Daewoo Motors was acquired by General Motors in 2002. The Lanos was subsequently rebadged and sold as the Chevrolet Aveo in many markets.
