A pair of major manufacturers, Toyota and Chrysler, seek to join the roster of MICHELIN^® GREEN X^® Challenge winners in the American Le Mans Series two-hour race at Long Beach Sat., April 20.

Rebellion Racing (Toyota) and SRT Viper (Chrysler) are poised to become the latest manufacturers to claim victory in America’s premiere environmental motorsports competition. Fourteen different manufacturers have earned at least one MICHELIN GREEN X Challenge award. Previous Long Beach winners include Acura, Aston Martin, BMW, Ferrari, Honda (HPD) and Porsche.

“The competition in the MICHELIN GREEN X Challenge is every bit as close as the competition in the race itself,” said Silvia Mammone, manager motorsports marketing, Michelin North America. “In our first 39 races (78 awards), 33 of the MICHELIN GREEN X Challenge winners also won their respective class in the race.”

The Toyota-powered Rebellion Racing prototype won the 2012 season-ending Petit Le Mans race and finished third overall in the 2013 Twelve Hours of Sebring last month.

The SRT Vipers are in their first full season of ALMS competition after competing at selected 2012 events and recently led the GT class at both the 2012 Petit Le Mans and 2013 Twelve Hours of Sebring.
