DETROIT - General Motors is searching for ways to add capacity for its popular mid-sized SUVs.
Tom Wallace, vehicle line executive for the vehicles, says GM wants to add vehicles and variants on the GMT360 architecture that spawned the Chevrolet TrailBlazer, GMC Envoy and Oldsmobile Bravada.
"We're going to continue to look for opportunities to spread the architecture," Wallace says.
GM added seven-seater EXT versions of TrailBlazer and Envoy last year. It will introduce three nameplates this year: the limited-production Chevrolet SSR roadster-pickup; the Envoy XUV, featuring a retractable top over the cargo area; and the Buick Rainier five-seat SUV.
The two plants making the SUVS - in Moraine, Ohio, and Oklahoma City - can't keep up with demand. GM is running a "three on two" schedule in Moraine and two shifts in Oklahoma City.
In the three-on-two plan, a plant has three shifts working four 10-hour days per week, running the plant 20 hours a day.
"You can trust that we're doing ongoing studies on how to get more volume out of Moraine and Oklahoma City," Wallace says.
