The Lone Star Le Mans (previously known as 6 Hours of the Circuit of the Americas)[1] is an endurance race for Le Mans Prototypes and grand tourer-style cars held at the Circuit of the Americas in Austin, Texas.

Its first running was on 22 September 2013 as the fifth round of the 2013 FIA World Endurance Championship season.

On 2 December 2019, the Austin round of the WEC was revived for 2020, as a result of a conflict between the promoters at the Autodromo Jose Carlos Pace and the WEC, where the Austin round replaced the 6 Hours of São Paulo.

[3] On 9 June 2023, the schedule for the 2024 FIA World Endurance Championship was announced, with Austin returning to the schedule on 1 September as the 6th race of the season, effectively replacing the 1000 Miles of Sebring (a race specially created just for the WEC) as the American round of the championship.

On January 29 it was announced that the race would be cancelled with the official reason stated as a lack of entrants.
