A new standard has quietly been achieved

The redesigned cabin in the 2015 Sierra Denali combines triple door seals, inlaid doors and other refinements throughout the truck to create the quietest heavy duty GMC pickup ever. Add premium materials, supportive seats and generous storage and you've set the new standard in heavy-duty truck interiors. Denali also has heated and cooled Denali-embossed leather-trimmed front bucket seats, a heated leather-wrapped steering wheel, new soft-touch instrument panel with burnished aluminium trim and contrasting stitching.

Up close and personal

The 2015 Sierra Denali's all-new instrument panel puts controls where they're most visible - at your fingertips - and information at the sound of your voice thanks to a new available 20 cm diagonal colour touch radio with navigation system. Sierra Denali provides the latest technologies to help you work smarter and more efficiently. From available driver alert safety technologies to Denali's personalised driver display, you're surrounded by everything you need to perform your best.

Centre console storage

An available centre console storage compartment is designed to double as a filing cabinet, so you'll have a place to keep hanging files, a laptop and other mobile devices.

Signature lighting and engineered airflow

In a GMC pickup first, Sierra introduces new projected-beam headlamps fully integrated into the grille surround. The lamps are further enhanced by available LED signature lighting. In addition to triple door seals and thicker windscreen glass, Sierra's sculptured styling helps reduce wind noise to create a quieter cabin.
