GM to Spend $332 Million on Plant Upgrades

To produce more fuel-efficient engines


General Motors announced plans on Thursday to invest nearly $332 million in four U.S. manufacturing sites to produce more fuel-efficient engines and transmissions.

The commitment comes just days after the Detroit automaker reported a 6.4% increase in March sales, led by fuel-efficient cars as well as trucks and crossovers.

GM's vice president of U.S. sales operations, Kurt McNeil, at the time attributed the improvement to new products and the strengthening economy as American families become more financially secure.
