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. Sierra HD trucks have a new face that conveys GMC’s professional grade aesthetic with greater technical precision, including an all-new headlamp and grille design, power-dome hood - with specific badging on Duramax-equipped models - and a one-piece chrome bumper (body-color bumper on Denali). The 2015 Sierra HD lineup benefits from interior introduced on the 2014 Sierra 1500. Premium materials, greater attention to detail and purposeful technologies define the passenger space, with soft-touch materials and available aluminum trim providing premium accents to an interior designed to be a productive, easy-to-use environment.
