Carl Tavo Hellmund (born February 24, 1966, in Austin, Texas) is an American former racing driver and promoter. His partners and he are responsible for the United States Grand Prix being held in Austin, Texas, with the first race 16–18 November 2012.
Racing career 
Hellmund, a native of Austin, Texas, competed in the British Formula Three Championship in 1995 and 1996, and won races in the K&N Pro Series West and SCCA-sanctioned events, including the Winston West race in 2001.
Racing promoter 
Hellmund's father, Gustavo Hellmund-Rosas, was a racing promoter, having promoted the CART Copa Mexico 150 in 1980 and 1981. He promoted the Texas Racefest, a USAC regional short-track event from 2005–2009.
United States Grand Prix at Austin 
In July 2010, Hellmund announced he had signed a deal with Formula One in April to return the United States Grand Prix to the F1 schedule in 2012. Hellmund's investors, including Red McCombs and Bobby Epstein, are building a new track outside of Austin, Texas, that is being engineered by Herman Tilke and Peter Wahl. In November 2011, Ecclestone terminated the contract with Hellmund because he was unable to deliver the promised financing. On December 7, 2011 a new deal was agreed to between Formula 1 and the investors, McCombs and Epstein.
Since December 7, the construction of the circuit has been on pace to meet the race date. FIA's Race Director and Safety Delegate Charlie Whiting said: "The progress that’s been made since the last time I was here is amazing. I think the guys here have done an awesome job. It really is fantastic, everything’s built to the highest quality, exactly as we expected, and I’ve got absolutely no complaints."
