General Motors has unveiled the 2015 Chevrolet Silverado HD and GMC Sierra 2500 and 3500 at the Texas State Fair as it makes a bid to catch up to Ford Motor Co. in the race for heavy-duty truck sales. GM's re-engineered heavy-duty trucks boast of a new exterior and cab design and now include features found on the redesigned light-duty Silverado and Sierra 1500.
According to executives at GM, the improvements can increase Chevrolet and GMC's combined heavy-duty market share – currently at 36 percent – and surpass Ford’s 38 percent share. The heavy-duty truck market amounted to 435,000 units in 2012. According to GM’s estimates, Chrysler’s Ram holds 26 percent of the heavy duty market.
John Schwegman, executive director for U.S. product and pricing on GM trucks, said that they expect to “change the rank order of those numbers by brand with [their] new truck.Improvements include a more aerodynamic front end as well as doors inlaid into the body recesses to cut wind noise. Likewise a torsion bar allows for a gently opening rear tailgate.
GM added that the cab will be the quietest on the market. GM’s trucks are still powered by a 6.0-liter V-8 and a 6.6-liter Duramax turbodiesel, but with improvements in performance. GM now claims segment leadership when it comes to payload at 7,374 pounds and with regards to its conventional towing power of 19,600 pounds.
