2015 Chevy Silverado HD, GMC Sierra HD Star at State Fair of Texas
All-new Heavy-duty Pickups Set Segment Towing Mark
With ESPN analyst Mike Tirico making the call, GM recently introduced the stars of its new heavy-duty truck roster—the 2015 Chevy Silverado HD and GMC Sierra HD—at the State Fair of Texas.
“The new Silverado and Sierra light-duty trucks already are on the road, and now the folks at Chevrolet and GMC are unveiling these all-new heavy duty pickups that, like the record-setting athletes of today, raise the bar with their performance and capabilities,” said Tirico. “They are truly All-Pros.”
They’re also all-new, with each brand’s HD entries showing a heavy-duty evolution of the new design language from their light-duty counterparts. This includes sheet metal that’s been specifically massaged for improved airflow to ensure optimum power under heavy-duty loads.
“It is one thing to generate big power numbers in cool weather, and quite another to maintain power and torque when towing up a long grade on a blistering summer day,” said Jeff Luke, executive chief engineer with GM. “We think customers will appreciate all of the work that went into the cooling … when they get a chance to really put it to the test.”
Also likely to earn straight A’s will be the towing capability of the 2015 Chevy Silverado HD and GMC Sierra HD. Not only do they offer the segment’s highest conventional tow rating—of 19,600 lbs.—but they also boast features like Trailer Sway Control and Auto Grade Braking that work with the trucks’ cruise control for easy long-distance pulling (with diesel models getting an assist from Diesel Exhaust Brake technology).
“The customer sets the desired speed, and the truck will do the rest—increasing or decreasing power, downshifting to increase engine braking, and engaging the exhaust brake on the diesel engine,” explained Luke. “You feel much more confident and in control, because you aren’t constantly working to stay a step ahead of the truck and trailer.”
