Getting a Jolt From Volt

The introduction of our Chevrolet Volt concept car and E-Flex electric propulsion system at the North American International Auto Show in Detroit last month created quite a stir, garnering twice the media coverage as the runner up for us, our Chevrolet Camaro convertible.

The Volt came on the heels of our announcement at the Los Angeles show that we've begun work on a Saturn Vue plug-in hybrid, and puts a face on our efforts to diversify the energy sources we use to power automobiles.

However, some cynics accused us of pulling a PR stunt, saying the Volt is simply an attempt by GM to "greenwash" the public and would never be a real vehicle. The truth is just the opposite – we are treating Volt just like any other vehicle we do, giving it a dedicated development team and designating resources for it. With that in mind, I thought I'd take a moment to update you on the program so far.


As you probably know, the development of advanced, lithium-ion battery technology is the key to getting vehicles like the Volt on the road. For the last few months, we've been mobilizing GM's global resources to address the challenges posed by this issue. We've invested in an upgrade to our battery testing and development facilities and we've formed a dedicated battery team whose staff levels will increase by 30 percent over the next two years.

We have also named GM veteran Denise Gray to the newly created position of director of energy storage systems – some of us like to call her "GM's battery czar." Denise has more than 20 years of experience in such areas as powertrain, vehicle integration, electronics and software controls.

We signed two development contracts in January for lithium-ion batteries with two groups of suppliers - Cobasys/A123Systems and Johnson Controls-Saft. We also plan to talk to additional battery suppliers as well.

By the end of this year, we will begin testing the lithium-ion batteries developed in prototypes of the Vue Green Line plug-in hybrid. In the same timeframe, we also expect to have our first demonstration vehicles that use E-Flex. Our previously announced test fleet of Chevrolet Equinox fuel cell vehicles also use the E-Flex system, with a fuel cell stack instead of batteries as a prime supplier of electricity, a further demonstration of our commitment to electric drive and energy diversity.

Make no mistake: These programs are a top priority for GM. We have established aggressive product development timelines - even forming a special executive leadership council for the E-Flex program to expedite product decisions and regularly update those of us in senior management.

We're making progress, and you should expect to hear more in the near future. At the Detroit show we emphasized E-Flex's adaptability, from accommodating different vehicle designs to using various fuels and types of engines. We will prove that capability this year. Stay tuned, we'll update the program periodically here on FastLane.
