The second Firestone Twin 275s -- a pair of 114-lap IZOD IndyCar Series races under the lights -- will highlight the June 2012 racing calendar at Texas Motor Speedway.

Speedway president Eddie Gossage announced the track's schedule during a "No Limits" fan event at The Palladium Ballroom at Gilley's Dallas on Aug. 23.

The Firestone Twin 275s -- the first twin races in IZOD IndyCar Series history -- will be held June 9. Dario Franchitti of Target Chip Ganassi Racing and Will Power of Team Penske, who are locked in a series championship duel, each earned a race victory this past June.

"We revamped the majority of our schedule in 2011 in an effort to give our fans some variety and uniqueness to our season, and they wanted very much of the same for 2012," Gossage said. "The first-ever Saturday night (NASCAR Sprint) Cup race was a big success, the IndyCar twins format added a unique twist and the day-to-night appeal of the AAA Texas 500 for the Chase remains a fan favorite in the fall. The Texas Motor Speedway season has a little of everything for our fans."

The NASCAR Camping World Truck Series again will complement the IZOD IndyCar Series event weekend.
