Porsche will introduce an ethanol-mixed fuel in its Le Mans Prototype 2 RS Spyders for the July 7 American Le Mans Northeast Grand Prix at Connecticut’s Lime Rock Park.

According to an American Le Mans Series release, the four Porsche prototypes, entered by Penske Motorsports and Dyson Racing, now use the same E10 Ethanol fuel mixture as the GT2 Porsche 911 GT3 RSR race cars also entered in the two-hour and 45-minute contest.

“It is widely reported by the U.S. Department of Energy that the use of ethanol fuel can have huge energy and greenhouse gas emission reduction benefits,” said Peter Schwarzenbauer, president and CEO of Porsche Cars North America. “We are committed to make continuing efforts toward the success of this worthy global cause and encourage our customers to use this fuel when possible. The concerted use of ethanol-mixed fuel in the 911 and other Porsche models is one small, but effective means of protecting the environment.”

The American Le Mans Series highlighted its transition to alternative fuels with a display Thursday of sports cars and racing machines on the edge of Central Park.

“Energy Independence” was the message at Tavern on the Green as the Series showcased its relevancy – one of the watchwords since its early days.

More than 100 VIPs and media attended the luncheon program highlighted by remarks from legendary driver/team owner Bobby Rahal, Ethanol Promotion and Information Council (EPIC) Executive Director Tom Slunecka and American Le Mans Series President and CEO Scott Atherton.
