An overview of General Motors' Project Driveway Fuel Cell Program, milestones reached, lessons learned, and what's ahead in GM's effort to commercialize fuel cell vehicles.

1. General Motors’ Project Driveway and the Fuel Cell Electric Vehicle Scott BrierleyGeneral Motors Fuel Cell ActivitiesWestern Region

2. What is “Project Driveway?” The world’s first large-scale, real-world demonstration of Fuel Cell Electric Vehicles (FCEV). Comprised of 100+ FCEVs deployed in areas with existing hydrogen infrastructure (Southern California, New York, Washington, DC, Berlin) Participants include: The general public (i.e., Mainstream Drivers) Public policy makers and organizations Businesses Media Celebrities 2

3. The Purpose of “Project Driveway?” Real-World Data To understand performance, durability, and reliability of fuel cell vehicle technologies in a real-world setting before FCEVs come to market Driver Feedback All elements of the driving experience, including vehicle performance, fueling, and lifestyle fit Learnings Data are already influencing engineering, marketing, and research and development as GM continues to develop future electric vehicles 3

4. Where Are We Now? To-date, in 24 months GM’s FCEV fleet has accumulated 1.3 million miles 4

5. How Does A Fuel Cell Work? A fuel cell generates electricity through an electrochemical reaction between hydrogen and oxygen 5

7. An electric vehicle powered by GM’s fourth-generation fuel cell system.

8. Fully freeze durable

9. Start from temps > 5 ºF

10. Durable to temps > 5 ºFGM’s FCEV was honored with the Green Car Journal's 2008 Green Car Vision Award® Awarded over several nominees including the Honda FCX Clarity and Toyota Prius Plug-In

12. Why Fuel Cells? Twice as efficient as gasoline engines (Twice as far on the same amount of energy) Water vapor is the only emission A fuel cell vehicle is an electric vehicle (not a hybrid) (Better performance than most cars) Peak Power: 94 kW Continuous: 73 kW Torque: 236 lb-ft (320 N-m) Allow extended ranges and quick fill-ups for an electric vehicle (About 4-5 minutes to fill up)

14. 220 pounds lighter

15. Uses about a third of the platinum9

20. Summary Significant real-world lessons from FCEVs and Project Driveway drivers 1.3-million miles in about 24 months Substantial progress being made toward production-intent fuel cell system With proper fueling infrastructure, hydrogen fuel cells are a viable alternative to gasoline-powered vehicles 11
