The 2009 HUMMER H2
The 2009 HUMMER H2 will be the first HUMMER to utilize GM’s E85 FlexPower, with the H3 following later in 2009. The new H2 will be able to run on E85 ethanol, standard gasoline, or any combination of the two fuels. E85 is a cleaner-burning, higher-octane fuel that can help reduce dependency on oil, but may not necessarily achieve the same fuel economy as regular gas.
