Future Industries test course

The Future Industries test course is a large area located on the grounds of the Sato estate that is used to test Satomobiles and race cars produced by Future Industries.

History
After the brothers took up residence at the mansion, Mako and Bolin, as well as Asami, invited Avatar Korra to her father's mansion. When the Avatar asked what was on tap for that day, Asami told her that she had something "exciting in mind". She took her friends to the test course and, noticing Korra's interest, asked her if she could drive. Upon a negative response of Korra who noted that she only knew how to "drive" a polar bear dog, Asami offered to take her for a run on the track, to which Korra excitedly accepted. The two girls put on a helmet and got into a race car to race against one of the test drivers. Asami rode in pursuit almost the entire ride, but due to a risky move, she managed to overhaul the competition in the last meters and claim the victory.

Trivia

 * The layout of the track, the position of the grandstand, and the race car's designs can be compared to 1920s era Grand Prix motor racing.
