As the second half of the 2012 American Le Mans Series season begins, MICHELIN^® GREEN X^® Challenge leaders in both the Prototype and GT categories also lead their respective series championships for on-track race performance.

That is not a surprise to Scot Elkins, COO of the American Le Mans Series and overseer of the MICHELIN GREEN X Challenge.

“Clean, fast and efficient performance not only wins races, it usually delivers great results in the MICHELIN GREEN X Challenge, too,” said Elkins.

America’s leading environmental motorsports competition recognizes clean, fast, and efficient performance using a program developed by the Green Racing steering team comprised of representatives of the U.S. Department of Energy, the Environmental Protection Agency, SAE International and the sanctioning International Motorsports Association.

Leading the MICHELIN GREEN X Challenge Prototype standings and the ALMS LMP1 Prototype season championship is the Benicia, California-based Muscle Milk Pickett Racing HPD Honda team with drivers Klaus Graf and Lucas Luhr.

New Hudson, Michigan-based Corvette Racing and its #3 Corvette C6.R with drivers Jan Magnussen and Antonio Garcia lead both the MICHELIN GREEN X Challenge GT standings and the ALMS GT championship.

“For General Motors and Corvette Racing our goals at each race are always to win both the race and the MICHELIN GREEN X Challenge,” said Doug Fehan, program manager Corvette Racing. “And, make no mistake; we want both of those championships.”

“When we started the MICHELIN GREEN X Challenge program four years ago, we were not sure what to expect in terms of a correlation between race winners and MICHELIN GREEN X Challenge winners,” said Silvia Mammone, Michelin motorsports manager.

To date, 28 of the 66 MICHELIN GREEN X Challenge winners have also won their respective classes in the ALMS races.

All ALMS LMP1, LMP2 and GT class entries from all four ALMS tire makers are automatically entered in the MICHELIN GREEN X Challenge.
