GMC debuted the 2014-MY Sierra 1500 Denali full-size pickup with 6.2L EcoTec3 V-8 on September 12, 2013, giving select automotive journalists in Los Angeles the opportunity to be the first to drive the new, optional engine.

Sierra’s 6.2L V-8 will also be available for Sierra SLT models this fall. With this engine, which produces an estimated 420 hp and 450 lb.-ft. of torque, the Sierra is expected to have a class-leading maximum trailering capacity of 12,000 pounds, according to the automaker.

On the exterior, the truck has a signature Denali chrome grille, unique 20-inch chrome wheels, unique interior decorative trim, a polished stainless steel exhaust outlet and body-color front and rear bumpers. Denali-specific interior details include script on the bright door sills and embossed into the front seats and real aluminum trim.

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.

Other features standard on Sierra Denali include projector-style headlamps with LED signature daytime running lights, a Bose audio system, heated and cooled leather front bucket seats, a heated steering wheel, front and rear park assist and a power sliding rear window with defogger.

A 5.3L EcoTec3 V-8 is standard for the 2014 Sierra Denali. It produces 355 hp and 23 mpg highway on 2WD models.

Sierra Denali will be available with two option packages, including a Z71 Off-Road Package (4WD only) with monotube Rancho shocks, Hill Descent Control and transfer case shield, and a Driver Alert Package that includes Lane Departure Warning, Forward Collision Alert and patented Safety Alert Seat Technology.

Standalone options include the 6.2L EcoTec3 V-8, a sunroof and Rear Seat Entertainment.
