This is the new-for-2013 Škoda Octavia, with a background pony in the foreground:
Škoda, a Czech automaker acquired by the Volkswagen Group in 2000, built a small car called Octavia through the 1960s, and revived the name in 1996. The new Octavia shares the VW MQB platform with the Audi A3 and the newest VW Golf. Of course, it won’t be coming here.
