Austin's Circuit of the Americas endured an at times difficult birth to emerge as one of the most impressive new circuits to grace the racing calendar in recent years.
Created with the express intention of reviving the USA's hopes of hosting an F1 Grand Prix, the initial plans were first proposed in July 2010. Promoter Tavo Hellmund – a former racing driver who had competed in Formula 3 in the 1990s – had secured a deal with Bernie Ecclestone for a US GP from 2012 onwards. A parcel of 890 acres of undeveloped land in Travis County would be used for the circuit, with Texas billionaire Red McCombs and Bobby Epstein among the major investors.
The initial track layout was conceived by Hellmund, Texan motorcycle world champion Kevin Schwantz and renowned F1 circuit designer Hermann Tilke. Inspiration was taken from other circuits around the world, with the first section in particular taking its cues from Silverstone's Maggots-Becketts-Chapel complex. Other sections mimicked the stadium section at Hockenheim and Istanbul Park's Turn Eight and there was considerable elevation change, with a steep rise to Turn One among the most notable features.
The new circuit passed its FIA inspection with flying colours in September, ahead of the inaugural F1 race in November.
When the F1 circus arrived, the drivers and teams were immediately impressed. The paddock facilities were well thought out and lacked for nothing and spectators found the same was true of the public amenities. A central 'Grand Plaza' covering 20 acres contains a wide range of concessions, retail and restroom facilities and entrances to spectator seating, as well as a large reflecting pool, lawn, and varying landscape zones.
Dominating the skyline is the observation tower, which was conceived as a visual finale to the central Grand Plaza as well as a dramatic and memorable backdrop for the Austin360 Amphitheater concert venue at its base. Inspired by the image of red streaks of glowing light that tail lights leave behind in the dark, a roof of red steel tubes fans out over the amphitheater stage then converges at the base of the tower to form a "veil" that sweeps up and over the central elevator core.
To reach the top of the tower, visitors can either ride a high-speed elevator or climb the 428 steps to their destination. Seemingly suspended from the red pipe steel canopy is a viewing deck that offers a sweeping panorama of the entire track, downtown Austin, and the nearby Hill Country from an elevation of 230 feet. A portion of the floor is structural laminated glass, allowing more daring visitors to look straight down to the ground below their feet.
The circuit layout itself was much praised by the drivers, who found the first sector in particular a rewarding challenge. And the first race delivered a memorable result, with the McLaren of Lewis Hamilton hounding Red Bull's Sebastian Vettel into a mistake while lapping traffic to secure a deserved victory.
Since 2017, the Circuit of the Americas deals as the host venue for the final round of the 24H SERIES CONTINENTS
