Chevrolet Volt Concept Electric Vehicle

“That’s why we are also showing a variant of the Chevrolet Volt with a hydrogen-powered fuel cell, instead of a gasoline engine EV range-extender,” said Lauckner. “Or, you might have a diesel engine driving the generator to create electricity, using bio-diesel. Finally, an engine using 100-percent ethanol might be factored into the mix. The point is, all of these alternatives are possible with the E-Flex System.”

The Volt concept car is built on a modified future architecture, Lauckner said, similar to the one GM uses for current small cars, such as the Chevrolet Cobalt and HHR.

According to Larry Burns, GM vice president for research and development and strategic planning, the world’s growing demand for energy and its dependence on oil for transportation is the common theme behind today’s headlines.

“Whether your concern is energy security, global climate change, natural disasters, the high price of gas, the volatile pricing of a barrel of oil and the effect that unpredictability has on Wall Street – all of these issues point to a need for energy diversity,” said Burns. “Today, there are more than 800 million cars and trucks in the world. In 15 years, that will grow to 1.1 billion vehicles. We can’t continue to be 98-percent dependent on oil to meet our transportation needs. Something has to give. We think the Chevrolet Volt helps bring about the diversity that is needed. If electricity met only 10 percent of the world’s transportation needs, the impact would be huge.”

GM’s E-flex System enables multiple propulsion systems to fit into a common chassis, using electric drive to help the world diversify energy sources and establish electricity from the grid as one of those sources.

“The DNA of the automobile has not changed in more than 100 years,” said Burns. “Vehicles still operate in pretty much the same fashion as when Karl Benz introduced the ‘horseless carriage’ in 1886.

“While mechanical propulsion will be with us for many decades to come, GM sees a market for various forms of electric vehicles, including fuel cells and electric vehicles using gas and diesel engines to extend the range. With our new E-flex concept, we can produce electricity from gasoline, ethanol, bio-diesel or hydrogen.

“We can tailor the propulsion to meet the specific needs and infrastructure of a given market. For example, somebody in Brazil might use 100-percent ethanol (E100) to power an engine generator and battery. A customer in Shanghai might get hydrogen from the sun and create electricity in a fuel cell. Meanwhile, a customer in Sweden might use wood to create bio-diesel.”
