General Motors Co (GM.N) is boosting production of its highly profitable large SUVs and trucks to a pace that could result in 48,000 to 60,000 additional vehicles for the 2016 model year, in a bid to capitalize on rising demand, sources told Reuters. GM’s Arlington, Texas, plant that makes full-sized sport utility vehicles including the Cadillac Escalade and Chevrolet Suburban added Saturday overtime shifts beginning on Aug. 1, a GM spokesman confirmed on Thursday.
