“At GM, we believe tomorrow’s automobiles
must be flexible enough to accommodate
many different energy sources. And a
key part of that flexibility will be enabled by
the development of electrically driven cars.”

Ethanol potential assumes 50% FFV production from all OEMs from 2012, and the FFV parc uses E85. Adjusted for energy equivalency with gasoline. Oil information source: EIA – 2007 Annual Energy Outlook Table 11.
E85 Ethanol Has Even Greater Potential to Reduce Oil Imports if 50% of All U.S. Vehicles Were FFV

General Motors & Coskata PartnershipGeneral Motors & Coskata Partnership
¶ GM senior leadership is committed to enhancing the commercialization of cellulosic ethanol
¶ GM has reviewed the leading cellulosic ethanol technologies and potential producers & selected to first partner with Coskata
¶ Offers unique technology¶ Utilizes versatile input materials¶ Offers cost-competitive ethanol production¶ Makes sense environmentally from a lifecycle perspective
¶ Coskata and GM will work together on:¶ Testing fuel from Coskata pilot plant in GM vehicles ¶ Explore using GM plant waste to make ethanol and assist GM goal
of zero landfill use by its manufacturing facilities ¶ Making ethanol from renewable sources, used tires, and municipal
waste¶ Global marketing of next generation ethanol

¶ What does Coskata do? ¶ Using proprietary microorganisms
and patented bioreactor designs, the company will produce ethanol for under US$1.00 per gallon almost anywhere in the world, from a wide variety of inputs.
¶ GM has taken an undisclosed strategic ownership position of Coskata to work on rapid commercialization of “The Next Generation of Ethanol”

¶ Efficient¶ Able to make more than 100 gallons of ethanol from 1 ton of dry material¶ Uses less than one gallon of fresh water per gallon of ethanol produced,
compared with three to four gallons for ethanol today ¶ Reduces greenhouse gas emissions by as much as 84% compared to
conventional gasoline¶ Returns up to 7.7 times as much energy as is used in the ethanol
production process
¶ Affordable¶ Ethanol produced for under $1 per gallon, which should equate to 50
cents to $1.00 less than gasoline at the pump
¶ Flexible¶ Multiple non-food sources are used to make ethanol¶ Geographically flexible by using resources from almost every country
around the globe

How does a 2-Mode Hybrid save fuel?While Stopped: Auto Stop at 0 MPH. Battery power provides accessories
power, AC/heat, power steering, etc.
Low Speeds: Battery power alone drives vehicle at speeds up to about
30 MPH
Mid-High Speeds: Active Fuel Management 4-cylinder mode is utilized to a
much greater extent Hybrid electric boost provides enough power to only need
4-cylinders at highway speeds
Results: 50% City & 30% Overall MPG Improvement
