GM introduced a facelifted sedan at Auto Shanghai 2005, designed in cooperation with PATAC.
Bearing the internal code T250 and sold in South Korea as the "Daewoo Gentra", revisions included exterior styling changes, a new interior instrument panel and minor equipment changes, including increased sound deadening.
Incorporation of the radio antenna into the rear glass and extensive wind tunnel testing helped reduce the coefficient of drag from 0.348 to 0.326.

A facelifted hatchback with the sedan's updated instrument panel was presented as the Chevrolet Aveo during the Frankfurt Motor Show 2007, to be marketed in Europe and North America.
The Korean market received its own distinct restyle of the hatchback, the Gentra X, whose bumper without the distinctly "Chevrolet" split grille was also used for the Pontiac, Holden and Suzuki variants.

With launch of the Gentra X in South Korea, GMDAT had replaced engines of T250.
1.2 L (1206 cc) S-TEC II engine was updated with features such as dual overhead camshaft (DOHC) and timing chain (older version has timing belt) system.
1.6 L E-TEC II engine has been replaced with an updated GEN-III Ecotec Family 1 engine with new features such as variable valve timing mechanism.
