HORSEPOWER, AERO, ROLLING RESISTANCE AND MICHELIN® GREEN X® CHALLENGE AT ROAD AMERICA

ELKHART LAKE, WIS. (August 18, 2010) - The scenic hills of Wisconsin's Kettle Moraine countryside provide a fitting setting for America's premier environmental motorsports competition, the MICHELIN® GREEN X® Challenge, as the seventh stop of the 2010 American Le Mans Series rolls into "America's National Park of Speed," Road America (August 22).

Designed to help accelerate the development of new technologies and energies through motorsports competition, the MICHELIN® GREEN X® Challenge has grown into a global program including the prestigious 24 Hours of Le Mans, events in Europe, Asia and every ALMS event. The Prototype and GT winner are the cars that go farthest, fastest with the least environmental impact as determined by a U.S. Department of Energy formula.

"Horsepower is a big factor at Road America, so it will be very interesting to see how the cars with the fastest straightaway speeds fare both in the race and in the MICHELIN® GREEN X® Challenge," said Silvia Mammone, Michelin Motorsports manager. "We expect that the MICHELIN® GREEN X® Challenge at Road America will place heavy emphasis on fuel efficiency, aerodynamics, and the rolling resistance of tires."

Featuring a pair of long straightaways and several high speed corners, Road America is one of the fastest tracks of the American Le Mans Series season, with lap speeds averaging over 136 miles per hour.

"Tires are rotating nearly 3,000 times on each lap of the 4.048-mile circuit. Anything that reduces the energy used by the tires is important," said Mammone. "With elevation changes, a number of high- and mid-speed corners and a pair of long straightaways, The handling and braking characteristics of the tire will also be important as they all contribute to efficiency."

Clearly showing the link between efficiency on the track and in the MICHELIN® GREEN X® Challenge, 15 of our winners to date also won their respective class in the race.

ABOUT THE MICHELIN® GREEN X® CHALLENGE The American Le Mans Series is the only series currently recognized as "Green Racing" by the U. S. Department of Energy; Environmental Protection Agency and SAE International.

All five energy sources identified as part of the United States government energy policy (E10 ethanol blended gasoline, E85R gasoline blended ethanol, GTL (natural gas to liquid) biodiesel, E10-electric hybrid power and Iso- butanol gasoline) have been used in ALMS competition.

The MICHELIN® GREEN X® Challenge trophies are presented to the respective Prototype and GT winners. The bases for the unique MICHELIN® GREEN X® Challenge trophies are made of rubber recycled from MICHELIN® GREEN X® labeled consumer tires.
