The 2001 European Le Mans Series season was the only season for the IMSA European Le Mans Series. It is a series for Le Mans Prototypes (LMP) and Grand Touring (GT) race cars divided into 4 classes: LMP900, LMP675, GTS, and GT. It began 17 March 2001 and ended 6 October 2001 after 7 races.
The series came about following the expansion of Don Panoz's American Le Mans Series to include European rounds in 2000. The ELMS become a separate series for 2001, although following the same IMSA and ACO rules that the ALMS followed, and even having shared events among the two series. Like the Petit Le Mans for the ALMS, the 1000 km of Estoril was meant to be a unique event that would earn automatic entries to the 24 Hours of Le Mans for its winners. A lack of interest from the European racing community and competition from the FIA's series, meant that this would be the only season of ELMS. Another planned series, known as Asian-Pacific Le Mans Series (APLMS) was planned to begin in late 2001, but never occurred. The Le Mans Endurance Series was eventually renamed the European Le Mans Series in 2012.
Following the demise of the European Le Mans Series, the ACO would attempt to create another European-based sportscar series in 2003 with the more successful Le Mans Endurance Series.
With the Automobile Club de l'Ouest (ACO) allowing Don Panoz to bring the rules and racing formulas of the 24 Hours of Le Mans to America with the creation of the Petit Le Mans in 1998, Don Panoz attempted to build up a series to be based around Petit Le Mans. The aged IMSA sportscar series was taken over and became the new American Le Mans Series, and met with much success in 1999. Following this success, Panoz attempting to bring sportscar racing back to Europe, which had lacked a major sportscar series since the demise of the World Sportscar Championship in 1992. This led to the 2000 American Le Mans Series season, which included two races in Europe as the Nürburgring and Silverstone Circuit, as well as a round in Australia. These races would serve as a precursor to what would become the separate European Le Mans Series in 2001.
