DETROIT – General Motors is rolling out a parade of more than 15 of its future vehicles at the North American International Auto Show, including some that had not been previously announced.

The new vehicles were greeted by wild cheers from hundreds of employees, dealers and retirees Sunday. The lineup included a new Cadillac concept car and a Chevrolet Spark subcompact that will get 40 miles per gallon.

GM Chief Executive Rick Wagoner told the crowd the vehicles are smaller, smarter and more fuel efficient, with "enough towing capacity" to pull GM out of its current troubles.

The parade was led by Michigan Gov. Jennifer Granholm and workers who are developing the Chevrolet Volt electric car.
