Most auto manufacturers see us moving either to all-electric or hydrogen-electric vehicles in the long term.
The hybrid and "Extended Range Electric Vehicles" are just interim technologies.

WASHINGTON, D.C. (CNNMoney.com) -- Top executives of BP and General Motors Corp., two of the world's largest corporations, outlined on Tuesday their visions for the future of renewable energy.
They came to the same bottom line: Hydrogen will likely fuel the cars of the future, although it could take 50 years to get there. Until then, each company will pursue different strategies for developing new energy sources.

"Relying on the internal combustion alone is probably not going to get us there," said Robert Babik, director of emissions, environment, energy and safety policy at General Motors (GM, Fortune 500). "The key is to let electrification of the vehicle play a critical role."

The E-Flex is a vehicle with an electric motor that also has an on-board electricity generator to charge the batteries on long trips or other times when the vehicle can't be plugged into an electric outlet. The generator could either be a conventional gasoline engine, an engine that runs on biofuel or, eventually, a bank of hydrogen fuel cells that Babik said could be the fuel of choice 50 years from now.

Executives from General Motors Corp. and Toyota Motor cast doubts yesterday about the viability of hydrogen fuel cells for mass-market production in the near term, reports The Wall Street Journal. The executives said electric cars will be a better way to cut emissions and improve fuel efficiency.
Speaking at the Geneva auto show, GM Vice Chairman Bob Lutz told reporters that advances in lithium-ion batteries will enable electric cars to drive up to 300 miles without recharging, making them more attractive to the mass market. He added that fuel cells are too expensive for mainstream use.
"If we get lithium-ion to 300 miles, then you need to ask yourself, Why do you need fuel cells?" Lutz was quoted as saying. "We are nowhere where we need to be on the costs curve" for fuel-cell vehicles.
Separately Toyota President Katsuaki Watanabe echoed the sentiment, saying that costs for fuel cells remain high and the infrastructure needed to distribute hydrogen is not in place.
