Daewoo History:
Daewoo was a South Korean conglomerate that entered the automotive sector in the 1980s. It was known for producing vehicles based on older GM platforms initially, before developing its own designs. GM acquired a controlling stake in Daewoo Motor in 2002.
Nubira Lacetti Evolution:
The Nubira (sold as Lacetti in many markets) was Daewoo's C-segment offering. The J200 generation, introduced for the 2004 model year, represented a significant styling and engineering update, designed by Pininfarina (sedan) and Giugiaro (hatchback), and built on a GM platform, showcasing the increasing integration with General Motors.
Manufacturing Locations:
Primarily South Korea, but potentially also assembled in other GM facilities globally.
