At the beginning of the year we brought you initial news of the planned Green Challenge being implemented by the organizers of the American Le Mans Series. The announcement was made at the Detroit Motor Show, however details of how the initiative – co-sponsored by the Energy Department, the EPA and SAE International – would play out were still being worked on at the time.
The series has now announced that the Green Challenge will kick off this coming October at the "Petit Le Mans" race at Road Atlanta. ALMS race cars running on clean diesel, E10 ethanol or cellulosic E85 will be ranked by how much fossil fuels they use and how many emissions they produce over the course of the race distance. The vehicles which go the farthest on the least with the least impact will receive the lowest scores (i.e. the highest ranking), with winners announced in both the prototype and GT classes. Although only the one race will feature the Green Challenge component this season, in 2009 the initiative will carry through the entire calendar.
