Bringing General Motors' total investment in its Wentzville, Missouri, plant to over a half-billion dollars in preparation for the new midsize trucks, GM today announced an additional investment of $133 million in a 114,000-square-foot stamping facility at the Wentzville site to make parts for both the existing full-size vans, the GMC Savana and Chevrolet Express, as well as future midsize pickups.

GM had earlier announced cumulative investments of $380 million. GM claims the on-site production of sheetmetal stampings improves quality and manufacturing efficiency.

The production targets for the new midsize trucks are unknown, but the Chevrolet Colorado's peak sales year was 128,359 units in 2005, along with 34,845 units of the GMC Canyon. After 2005, sales of the Colorado never reached six figures again, and in 2007, combined sales of the Colorado and Canyon dropped below 100,000 units. In comparison, the Toyota Tacoma has consistently sold more than 100,000 units every year, with the lowest sales year being 2010, when 106,198 units were sold.

Fuel efficiency is expected to be a major selling point on the new trucks , and the models could be offered with a class-exclusive diesel option, giving them even more of an edge in fuel economy.
