Possible new track in Rio

Autodromo Deodoro

There are plans to possibly build a 19-turn 1.8-mile road course and mile oval circuit in Rio de Janeiro called the Autodromo Deodoro.

The new race course will be available with a parking capacity for at least 10,000 vehicles. The facility will also feature areas designed for race schools, pubs and restaurants.

Appears too small for F1 and IndyCar.
