# 2013 American Le Mans Series

The 2013 American Le Mans Series was the fifteenth and final season of the International Motor Sports Association GT Championship being labeled as the American Le Mans Series, before merging up with the Grand-Am Rolex Sports Car Series in 2014.
As the IMSA and Grand-Am merger was announced on September 5, 2012, between NASCAR Holdings (Grand-Am's owner) and Panoz Motorsports, the 2013 season was the transition season as both series were now held under the NASCAR Holdings banner. As such, this is the 43rd season of the series dating back to the 1971 IMSA GT Championship.
It began on March 16 with the 61st running of the 12 Hours of Sebring and ended with the 16th running of the Petit Le Mans on October 19. At the seventh round in Baltimore, Muscle Milk Pickett Racing successfully defended their 2012 Prototype One championship.

## Calendar

The calendar was announced October 18, 2012. The race at the Circuit of the Americas near Austin, Texas, was previously announced in June 2012, and a combined event with the Rolex Sports Car Series at Road America was announced on September 28, 2012. The event at Mid-Ohio, a joint weekend with the IndyCar Series, was not renewed. The event at Mazda Raceway Laguna Seca was initially scheduled on May 18. However, with this date conflicting with the 24 Hours Nürburgring, the series opted to move the event up one week to May 11. The event was also shortened from 6 hours to 4 hours.
