As the checkered flag flew on this weekend's American Le Mans Series race at Road America, cars powered by cellulosic E85 dominated the Michelin Green X Challenge. One of the biggest proponents of biofuels in ALMS has been Lord Paul Drayson, a former UK science and technology minister. Drayson's co-driver, Jonny Cocker, drove the E85-fueled Lola-Judd to his second straight pole position and then went on to get Drayson Racing's first ever overall victory. Cocker won with a dramatic late-race surge from fourth to first in the final four laps, passing Klaus Graf with two corners to go. Despite the speed of the Drayson car, it was fuel efficient enough to win the Green Challenge title for the prototype class.
In the GT class, where 10 of the 12 competitors are now running on E85, the Team Falken Tire Porsche 911 GT3 RSR may have been running a bit too lean because it only finished 10th in class on the track; but at least it won the Green Challenge.
