The American Le Mans Series launched its Green Challenge last fall at the Petit Le Mans race at Road Atlanta. For 2009, ALMS is making it a season-long fixture. Today in Washington, D.C., ALMS CEO Scott Atherton announced that the French tire maker Michelin has signed on as a title sponsor of the Green Challenge. Participants in ALMS races will be evaluated on a formula that factors in fuel consumption and performance to produce a score based on which car extracts the most from the energy it uses. At each of the 2009 races, the tire maker will award the Michelin Green X Challenge award to the prototype and GT teams that get the best green scores. At the end of the season, the EPA, DOE and Society of Automotive Engineers will present the overall Green Challenge awards to the manufacturers with the best series-long performance.
