“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.”

¶Reduced dependency on foreign oil
¶Potential to add substantially to the fuel supply
¶Supports rural communities and the domestic agriculture industry

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”

Coskata – “The Next Generation of Ethanol”Coskata – “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

What is a Two-Mode Hybrid?What is a Two-Mode Hybrid? A traditional “One-Mode”
Hybrid typically has one torque splitting arrangement and no fixed mechanical ratios
GM’s “Two-Mode” Hybrid uses low & high speed electric continuously variable transmission modes combined with a fixed –gear transmission. One transmission with: 2 Electric motors 4 Fixed-gear ratios
Provides higher efficiency and no reduction in capabilities or performance

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
