OREANDA-NEWS.  An all-new 2014 Sierra 1500 Denali full-size pickup arrives this fall with an available 6.2L EcoTec3 V-8 that will produce an estimated 420 horsepower and 450 lb-ft of torque, the most power and torque of any light duty truck engine.

Final SAE-rated power and torque numbers will be available later this year. Now entering its third generation, the Sierra Denali is the most luxurious and technologically advanced GMC half-ton pickup.

Sierra’s 6.2L V-8 will also be available for Sierra SLT models this fall. With this engine, the Sierra is expected to have a class-leading maximum trailering capacity of 12,000 pounds. Like every 2014 Sierra, it offers more power and higher expected efficiency than its predecessor thanks to a trio of technologies including direct injection, active fuel management and variable valve timing.

Design cues for the 2014 Sierra Denali follow the formula that attracted two-in-10 GMC buyers to Denali vehicles last year. 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.

“The 2014 Sierra Denali has a combination of performance, capability and luxury that no other pickup can match,” said Tony DiSalle, vice president of GMC Marketing. “It leaves no boxes unchecked for those owners looking for the ultimate expression of ‘Professional Grade.’”

A 5.3L EcoTec3 V-8 is standard for the 2014 Sierra Denali. It produces 355 horsepower and offers better EPA-estimated fuel economy (23 mpg highway on 2WD models) than any V-8 or turbocharged V-6 pickup on the market.

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.
