Showing off hybrid vehicles in Detroit.

In Invasion of the Hybrids, BusinessWeek states that "The auto giants are putting the spotlight on their eco-offerings at this year's North American International Auto Show in Detroit."

"Hybrid vehicles are proliferating, and not just because gas prices spiked to above $3 per gallon last year. Auto makers showing off new hybrid vehicles and plans at this week's North American International Auto Show in Detroit realize that having a hybrid vehicle lineup is valuable public relations for their images."

While this might be true, it is very interesting to note that there are some very unique and radical ideas in many of these new hybrids. For example, GM will be releasing a dual mode hybrid powertrain, while Mitsubishi is showing off its In-wheel Electric Vehicle (MIEV) hybrid powertrain, and Ford is displaying the Reflex diesel hybrid vehicle.

The autoshow isn't just about hybrid vehicles, its about new hybrid technology, and it is also about new hybrid parts suppliers. To simply call this PR is an understatement.

So what hybrids are just around the corner?

Ford will add the Mercury Milan hybrid and the Ford Fusion to their hybrid lineup by 2008, along with their current hybrids, the Escape hybrid and the Mariner hybrid.

GM will offer its mild hybrid, the Saturn Vue Greenline Hybrid, next year which will be followed by the Chevrolet Tahoe hybrid, Chevy Equinox hybrid, the Chevy Malibu hybrid, and the Cadillac Escalade hybrid.

Honda will add the Ridgeline hybrid and Pilot hybrid.

Nissan has already announced the Altima hybrid, but the Sentra and Murano hybrids won't be far behind.

Hyundai, Volkswagen, BMW, Chrsyler, Puegeot, Subaru and even Porsche have all announced they will also offer hybrids.

Obviously, Toyota, which launched the Camry hybrid in Detroit, will continue to push full steam ahead into hybrids. "I think everything will be a hybrid, eventually. It will either be a gas hybrid, a diesel hybrid or a fuel-cell hybrid," Jim Press, Toyota's North American president and chief operating officer said.

Hybrid cars aren't just critical for the public realtions of auto corporations, hybrid technology is critical for their very survival.
