All-new 2014 GMC Sierra Denali made is debut today and showed its 6.2-liter V8 engine capable to pump out 420 hp and 450 pounds-feet of torque. This means a 20 hp increase comparing it with the outgoing model. For the first time on the Sierra Denali, the 6.2-liter V8 engine will be offered as an option, while a 5.3-liter V8 will come as standard.
The 5.3-liter V8 delivers 355 hp and 383 pounds-feet of torque. According to the official press release, the 5.3-liter EcoTec3 V8 engine promises an EPA-estimated fuel economy of 23 mg highway on 2WD models, better than any V8 turbocharged V6 pickup on the market. In terms of design, the 2014 Sierra Denali comes with the signature chrome grille, new 20-inch chrome wheels, unique decorative trim, polished stainless steel exhaust outlet and body-color front and rear bumpers.
Inside, the truck comes with an 8-inch Customizable Driver Display that can show relevant settings, audio and navigation information in the instrument panel. The 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 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.
2014 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.
With new aerodynamic features, the 2014 Sierra offers both fuel efficiency and reduced wind noise. The redesigned mirrors help reduce wind turbulence while its triple-sealed inlaid doors, roof and tailgate design features allow air to smoothly flow over the GMC Sierra. To lower drag, the 2014 Sierra comes with more sealing around its grille, headlights and the space in between the cab and box, as well as, new aerodynamic spats on the front of its rear wheels.
The 2014 Sierra also comes with an updated body and chassis to improve ride and handling, as well as, comfort and capability. It makes use of high-strength steel for the fully boxed frame and applies hydroforming technique to reinforce strength and rigidity while reducing weight. The A- and B-pillars, roof rails and rocker panels are made of high-strength steel while its rocker panels are made of ultra-high-strength steel segments which also provide protection during shallow offset crashes. Its hood is made of aluminum which further reduces the weight by 17 pounds compared to those with a steel hood. Out back, the roll-formed box is designed to be stronger, lighter and more durable as opposed to a traditional steel box.
Some suspension components use aluminum to increase rigidity while reducing weight. Furthermore, it comes with new lightweight wheels with low-rolling-resistance tires – the latter, along with new shear-style and redesigned hydraulic cab mounts, also helps with noise and vibration reduction inside the cabin.
