VW reviewing future investments, but local officials remain upbeat on Chattanooga plant

Volkswagen's chief warned Tuesday the carmaker is reviewing its planned investments, but local officials remained upbeat about the company's expansion at its Chattanooga assembly plant.

"There's no reason to believe the plant won't move forward," said Hamilton County Mayor Jim Coppinger as the company continued work on a $600 million project to produce a new SUV that VW officials believe is key to U.S. sales.

The Rev. Jesse Jackson, in Chattanooga on Tuesday, weighed in on the VW emission-rigging issue, saying the company must make "strong corrective actions, but [the plant] must not be closed."
