At which real racetrack did Pixar premiere Cars in 2006?

Pixar premiered Cars at Lowe's Motor Speedway in 2006.

The world premiere took place on May 26, 2006, at Lowe's Motor Speedway in Concord, North Carolina. The venue, now known as Charlotte Motor Speedway, was an especially fitting setting for a film about stock-car racing and American automotive culture.

Cars then received its wide United States theatrical release on June 9, 2006. The premiere connected the animated film with a real motorsports audience before the story introduced viewers to the fictional racing world of Radiator Springs.

The track's name has since changed: it became Charlotte Motor Speedway in 2009. Therefore, Lowe's Motor Speedway is the historically correct name for the venue at the time of the Cars premiere.
