The layout for Austin's US Grand Prix circuit includes more than 20 corners
The design of the Texas circuit which will stage Formula 1's return to the United States has been revealed.
Construction of the Hermann Tilke-designed circuit in Austin is scheduled to begin in December with the US Grand Prix due back on the calendar in 2012.
The 3.4-mile track aims to blend features of classic tracks, such as Silverstone, with modern facilities.
"For the competitors, we'll have all the ingredients necessary," said race promoter Tavo Hellmund.
"You'll see fast turns that require commitment from the drivers and technical turns that will test the engineers from a set-up point of view.
"It will have many of the elements of previous 'classic' circuits and amenities fans have come to expect in an ideal, world-class venue.
"We have a good deal of elevation to make it not only scenic but also challenging - and the view of downtown Austin is wonderful as well.
"In the modern era of grand prix racing, I think this track layout and topography will be very special."
Formula 1 supremo Bernie Ecclestone agreed a deal for the Texas capital to host a race until 2021 and, for the first time, a venue for the US GP will be purpose-built.
The last US Grand Prix took place at the famous Indianapolis Motor Speedway in Indiana in 2007, a race won by McLaren's Lewis Hamilton.
Its eight-year run was ended after Ecclestone failed to come to an agreement with the circuit's chiefs over new terms.
Watkins Glen in upstate New York, Long Beach, California, Las Vegas, Detroit, Dallas and Phoenix have all hosted F1 races in the past.
