Siwon and actor Ha Jung Woo have become the faces of 'Audi'.

The pair are well loved for their masculine images. Ha Jung Woo won numerous awards through his acting, and Siwon is one of the top Hallyu stars that handle all genres such as dramas, movies, CFs, and concerts.

The pair will be attending Audi's official events and work hard as the promoters of the car brand. While they are the brand's models, Ha Jung Woo will be driving the Audi S8, while Siwon will be driving the Audi R8 Spyder.

Audi said, "Ha Jung Woo and Siwon both have a sophisticated image. Not only that, but they're amazing actors and have excellent artistic taste. They'll be creating a synergy effect with the dynamic prestige brand Audi."

Siwon also tweeted about his Audi promotions, writing,
