In the United States, the platform-sharing lineup consisted of the Saturn Sky and Pontiac Solstice, but abroad, the Kappa was known as both the Daewoo G2X in Korea and the Opel GT in Europe.

The Seoul Motor Show features the fourth variant of General Motors' Kappa platform and the third based on the Saturn Sky. The new GM Daewoo G2X is a rebadged edition of the Sky and Opel Speedster.
