DALLAS – Designed to deliver class-leading capability with enhanced comfort and smarter technologies, the new 2015 GMC Sierra HD lineup advances a 111-year legacy of professional heavy-duty trucks.

The new Sierra HDs arrive in the first quarter of 2014, including 2500HD and 3500HD models, and the Sierra Denali HD, which matches do-it-all capability with an exclusive package of design and upscale interior amenities.

Segment-leading capabilities across the range include the highest payload – 7,374 pounds – and the highest conventional trailering rating – 19,600 pounds. The maximum fifth-wheel trailering rating is 23,200 pounds. Gas and Duramax diesel powertrains are offered, including a bi-fuel option that pairs the gas engine with a compressed natural gas system.

“Sierra HD trucks are engineered without compromise to deliver not only the capability today’s heavy-duty truck customers demand, but the quality and refinement that inspire confidence with every task,” said Tony DiSalle, vice president of GMC Marketing. “We’ve been doing this for more than a century, and nobody knows trucks like GMC.”

Bold styling and an all-new, more comfortable and technology-infused interior are carried forward from the 2014 Sierra 1500, including new double cab and revised crew cab body styles. Larger rear doors on each, along with new seat designs, enable easier entry and exit from the rear seat and two inches of additional legroom on crew cabs.

The new interior is also designed to help drivers and passengers whether they’re on the job or on a weekend getaway, with easier-to-reach, more intuitively located controls, more storage compartments, more plug-ins for electronic devices and the latest-generation GMC IntelliLink infotainment system – with an eight-inch-diagonal color touch screen.

“Forget the notion that heavy-duty trucks are basic tools with a trailer hitch,” said DiSalle. “The 2015 Sierra HD trucks can haul the heaviest load with unmatched comfort and technology that make the job easier.”

Additional new and enhanced features for the 2015 Sierra HD lineup:

• CornerStep rear bumper, EZ Lift and Lower tailgate, standard upper tie-downs and other features that make cargo handling easier

• Standard StabiliTrak with Trailer Sway Control on all models, including 3500HD dually

• Integrated cruise control, auto grade braking and diesel exhaust braking (diesel models), for greater driving control and reduced brake wear on grades

• Enhanced cooling airflow, which enables the Duramax turbo diesel and 6.0L gas engine to better maintain full power, even under heavy loads and high ambient temperatures

• Latest-generation IntelliLink infotainment system, which offers a variety of connectivity options for devices of all types and available navigation

Sierra Denali HD details

The distinctive Sierra Denali HD features a signature Denali chrome grille, unique interior decorative trim, a polished stainless steel exhaust outlet (gas models) and body-color front and rear bumpers. Complementing the soft-touch instrument panel trim and aluminum trim are Denali-specific interior details, including script on the bright door sills and embossed into the front seats.

Sierra Denali’s high-tech interior also features an exclusive eight-inch customizable driver display that can show relevant settings, audio and navigation information in the instrument panel. Sierra Denali’s standard eight-inch Color Touch navigation radio with Intellilink, located above the center console, serves as the main hub for Bluetooth-connected phones and portable devices connected through five standard USB ports.
