As you can see here, we have realized tremendous performance improvements in terms of power density as we move from generation to generation with our fuel cell stack technology. Yesterday, Rick Wagoner told you about General Motors' strong commitment to innovative products and technology. From Mechanical to Electromechanical to Electronic One of the big accelerators of change is the rapid advancement of automotive electronics and its convergence with advanced propulsion technology. Electronics already are employed in vehicles for everything from smart sensing and controls to mobile information and entertainment systems. This has transformed the vehicle from a purely mechanical device into an electromechanical system.
Electronic control is key to improving powertrain performance.
As we marry electronics with electric drive in our advanced vehicles, we are fast approaching the day when the automobile undergoes another metamorphosis and moves from being an electromechanical device to one that is largely electronic. At GM, we are exploring a suite of technologies to bring this day closer. Advanced internal combustion engines that rely heavily on electronic controls to lower emissions and improve fuel economy. Hybrid-electric vehicles like our Partnership for a New Generation of Vehicles demonstration car, the GM Precept, which pairs an advanced diesel engine with our Generation III electric drive. In this visual, you can see our framework for focusing all of GM's advanced technology development work.
