The number of confirmed events on the 2007 IRL IndyCar Series schedule has risen to seven with news that the 1.33-mile concrete surfaced Nashville Superspeedway has retained its place on the calendar.

Nashville will retain its mid-summer date with the weekend of July 13-14 set to host both Saturday's night's IRL event and a supporting Indy Pro Series race.

"We are pleased to be returning to Nashville Speedway and bringing the IndyCar Series to Firestone's home city," said Brian Barnhart, president and COO of the Indy Racing League, the sanctioning body for the IndyCar Series and Indy Pro Series. "The concrete pavement at Nashville brings an exciting element to our diverse schedule of super speedways, short ovals, road and street events."

The 1.33-mile concrete oval located near Gladeville Tennessee has hosted IndyCar Series racing since 2001 and the Indy Pro Series since 2002. The track is the only concrete venue on the schedule and has produced one of the most competitive events in IndyCar Series history with six race winners in as many events.

The track's hand-painted Gibson guitar trophy is one of the series' most-sought after prizes.

"The IndyCar Series continues to be a fan favourite, and we are thrilled to have the series back in 2007," Nashville Superspeedway Vice President & General Manager Cliff Hawks said.

Nashville now officially joins St Petersburg, Indianapolis, Milwaukee, Texas, Kentucky and the new Iowa Speedway on the 2007 IRL calendar.
