MICHELIN GREEN X Challenge

The MICHELIN® GREEN X® Challenge, a premier motorsports environmental competition, challenges all American Le Mans Series Prototypes and GT entries in the field to maximize their performance on the track and to accelerate the development of new technologies and energies through motorsports competition.

The MICHELIN GREEN X Challenge recognizes the cleanest, fastest, most efficient cars at each ALMS race.

Overseen by the Green Racing steering group, comprised of representatives of the U.S. Department of Energy, the Environmental Protection Agency, SAE International and the sanctioning International Motor Sports Association, the scores are determined by a combined score for “Clean, Fast and Efficient” performance.

First introduced by MICHELIN in 2006 as an Energy Efficiency award at the 24 Hours of Le Mans, the program was extended to the full European-based Le Mans Series in 2007 and launched in North America in early 2009 as the MICHELIN GREEN X Challenge.
