The Indianapolis Motor Speedway Centennial Era Concours d'Elegance, featuring some of the world's finest classic and antique automobiles and motorcycles, is moving to 17-19 June 2011, reports the Indianapolis Motor Speedway.

The event, originally scheduled for 18-20 June 2010, is shifting to the new date due to the challenging state of the world economy. IMS officials anticipate strong participation from concours and industry enthusiasts based on the tremendous initial response since the Centennial Era Concours d'Elegance was announced in March 2009.

The Concours d'Elegance will be a featured event during the Speedway's Centennial Era, honoring the 100th anniversaries of the opening of the fabled facility in 1909 and the inaugural Indianapolis 500 in 1911. The event will celebrate the significance of vehicular transportation and competition to Indianapolis.
