Circuit of The Americas has announced that motorsports legend Mario Andretti is to be an official circuit ambassador.

The racing superstar, with more than 100 major wins in virtually every racing series-including Formula 1, IndyCar, NASCAR, sprint cars, sports cars, dirt track cars and drag racing- is considered one of the most accomplished and reputable racing experts in the world. Andretti will work with Circuit officials to promote awareness of Formula 1 and the circuit's debut as a premier sports and entertainment complex.

"Circuit of The Americas is honoured to introduce Mario Andretti as our official ambassador to the motorsports world," said Circuit Executive Vice President Bruce Knox. "Mr. Andretti is a racing icon and is globally recognized as one of the most successful drivers in the history of motorsports. His record speaks for itself, as he is the only driver in history to win the Formula One World Championship, Indianapolis 500 and Daytona 500. Circuit of The Americas will benefit from Mr. Andretti's valuable input and representation as we prepare for the inaugural Formula 1 United States Grand Prix."

Andretti will make public appearances in the coming months to promote Circuit of The Americas and the inaugural 2012 United States Grand Prix at the Central Texas venue. This weekend, he will join a group of Circuit team members at the Grand Prix du Canada as they interact with Formula 1 fans, teams and drivers.

A visit to Austin on Thursday allowed Andretti to get a preview of what is to come in November. His visit to the Circuit included a tour of the track and facilities currently under construction. Paving is ongoing at Turns 1-9 and Turns 18-20. Significant progress has also been made on the pit building and main grandstand, as well as on the 5,500-square foot media centre and state-of-the-art medical centre.

"Formula 1's return to the United States is so exciting for racing fans, especially at a purpose-built facility," said Andretti. "Circuit of The Americas has a strong team behind it that is working day in and day out to prepare for the first race. They have made significant progress in a short amount of time. The track design has really come together, and it's clear that this will be a phenomenal venue for a variety of premium motorsports. I know I'll be there this November to help the Circuit of The Americas team welcome back F1 in grand fashion!"
