GM, the industry leader with more than 3 million flex-fuel vehicles on the road in the United States, has pledged to double flex-fuel production by 2010 and make half its portfolio E85-capable by 2012.

As part of that commitment, GM’s HUMMER Division revealed the 2009 E85-capable H2 SUT at Classic Hummer on Friday, one of more than 15 FlexFuel models GM will offer for the 2009 model year. The H2 also will be E85 capable for 2009.

“We’ll offer a biofuel powertrain in every model we build by the end of 2010,” HUMMER General Manager Martin Walsh said. “A Hummer’s off-road capability and care for the environment are in no way mutually exclusive. This is simply one more step in our effort to promote responsible adventure.”
