Back at the end of August, I told you about how Ford was getting ready to debut a new engine that would be compatible with more blends of fuels, including B20 biodiesel. Today, at the State Fair of Texas, the automaker unveiled its new line of F Series trucks that will not only take the higher blend of biodiesel but also a line of engines that will take E85 ethanol.

This company press release says the new engine, which was code-named “Scorpion,” should make a pretty big, green splash:

* The 2011 F-Series Super Duty boasts all-new powertrains, led by the Ford-designed, Ford-engineered and Ford-built 6.7-liter Power Stroke® V-8 turbocharged diesel engine, which delivers significantly improved torque and horsepower as well as class-leading fuel economy while maintaining best-in-class towing and payload capability; new engine also has biodiesel compatibility up to B20

* A new 6.2-liter V-8 gasoline engine also is added to the lineup; it also delivers significantly improved torque and horsepower as well as class-leading fuel economy; new gas engine can run on regular-grade gasoline, E85 or any blend in between

Ford says the new trucks, due to the market in 2011, will have a six-speed transmission that gets the new diesel engine’s low-end torque to the ground faster and will come in an automatic or manual option.
