Toyota (NYSE: TM) is upping its bet on ion lithium-battery cars. It has set up a joint-venture with Matsushita Electric Industrial to start mass production of the power sources by 2010.

According to Reuters, "Toyota, the world's top maker of gasoline-electric hybrids, is keen to bring such vehicles into the mainstream by lowering their cost premium." Consumers can plug-in their cars before turning in for the night.

The news is another example of why Toyota stays more competitive than most other large car companies. Who would have seen the mass demand for alternative energy cars as oil doubled? Even Toyota could not have predicted that, but the firm was willing to make a significant investment that customers would continue to move away from gas even if prices did not spike up.

In Detroit, the last one to leave the building can pull the plug on the lights. At the US car companies, that is all electricity is good for.

General Motors Corp. (NYSE: GM), after seeing sales plummet for larger cars and SUVs over the past 18 months because of higher energy prices, is now doing a major about-face. It's no secret that a large part of GM's future strategy is tied up in alternative fuels and electric vehicles for the consumer market. Translation: inflation and energy prices are changing consumer gas price attitudes.

Robert Lutz, GM's product design expert extraordinaire (oh, and Vice Chairman), is placing a large bet on the Chevrolet Volt, a 100% electric vehicle that GM hopes will capture the imaginations -- and wallets -- of energy-conscious consumers. Lutz even calls the Volt GM's "moon shot" in a reference to a once-in-a-lifetime NASA goal to place a man on the moon in the 1960s. GM has a once-in-a-product-cycle chance to get a mass-produced, well-liked electric vehicle into dealer showrooms before any other global auto manufacturer.

Lutz, who speaks the best geek-speak there is concerning vehicle dynamics and drag coefficients, seems certain that GM can outfox Toyota Motor Corp. (NYSE: TM) by getting a popular, 100% electric vehicle into mass production first. Toyota's existing Prius is a hybrid (gas and electric), and the race is on to get a completely electric car onto the showroom floor. Since there is no gas engine, which provides power for air conditioners and many other components, all systems from entertainment to windshield wipers had to be created from the ground up for the new Volt. From reading this Lutz interview, the Volt has the potential to place GM on top of the auto world again. That is, if done right and before the competition beats it to the electric vehicle game.
