GM Escalates Output

General Motors Co.’s second-half production schedule is showing an upward trendline with the addition of 60,000 vehicles to its third- and fourth-quarter forecasts.

Demand for fuel-efficient vehicles prompted the move, which affects some 1,350 hourly workers and boosts output of the Chevrolet Cobalt small car and Equinox midsize cross-utility vehicle and all-new GMC Terrain midsize CUV.
