The automaker, which has made billions off its hefty trucks and SUVs over the years, said Tuesday that it's been over-promoting its largest vehicles and plans to change course.


Instead, GM will implement a "dramatic redesign" of its marketing strategy that places a much greater focus on its high-mileage cars, new hybrids and other fuel-efficient vehicles.

"We've been promoting our trucks more than we should have," Mike DiGiovanni, the company's top sales analyst, told a bankers' conference in Warren. "We're going to shift our marketing toward fuel economy and hybrids."
