The promoter for the revived US Grand Prix promised a fast track with sight lines that will let spectators watch most of the race from their seats.
Tavo Hellmund, managing partner of Full Throttle Productions, told The Associated Press that the 3.4m course will have 20 turns and elevations up to 133ft.
It will also include grandstands near the start and finish line for at least 20,000 spectators with room for 50,000 or more around the rest of the track. It could cost up to $220M (£142M) to build.
Hellmund called the design “a throwback to old, classic tracks” with several turns inspired by race courses in Europe.
Formula One officials were expected to formally announce details of the course designed by German firm Tilke on Wednesday.
Formula One hasn’t raced the US Grand Prix since it was last held at Indianapolis Motor Speedway in 2007. Formula One announced it had a 10-year deal to race in Austin beginning in 2012.
The race in the Texas capital would mark the first U.S. Grand Prix on a course specifically built for an F1 race.
The Austin track is designed to use the natural topography of gently rolling hills on 900-acres a few miles south east of the city centre.
Hellmund said designers delivered a track with difficult turns and straights to get drivers at speeds around 200 mph.
The design has been approved by Formula One boss Bernie Ecclestone, Hellmund said.
