DETROIT – The potential of electric-powered cars was a highlight of the 2009 North American International Auto Show (NAIAS) preview days, with several automakers unveiling their latest concepts and making big announcements.

In addition to revealing its all-new 2010 Ford Taurus, Ford also announced an aggressive plan to bring pure battery-electric vehicles, next-generation hybrids, and a plug-in hybrid to market quickly and more affordably during the next four years.

Chrysler also unveiled plans for its all-electric and range-extended electric vehicle (EV) portfolio across its vehicle lineup. The automaker plans to have at least one of the three prototypes introduced at the show by 2010.

General Motors premiered the 2010 Chevrolet Equinox, 2010 Cadillac SRX, 2010 Buick LaCrosse, and Cadillac Converj concept. Chevrolet also announced it will produce and bring to the U.S. the highly fuel-efficient Spark four-door mini car and seven-seat Orlando multi-purpose vehicle.

Toyota unveiled its new 50-mile-per-gallon third-generation Prius hybrid and debuted its FT-EV concept.

Last year's NAIAS featured a total of 58 vehicle debuts — 44 worldwide and 14 North American. Expected to draw more than 700,000 attendees including hundreds of celebrity names from all walks of life, nearly 7,000 international media from some 60 countries, and approximately 40,000 industry insiders from over 2,000 companies, other 2009 highlights during preview days include:
