In front, between the projector beam headlights, there is an incredibly striking and enormous chrome grille. While driving, it takes in a large portion of the air for cooling the engine, and lets the remainder glide across the truck. It is complimented by a bumper made of sculpted steel, a strong angled hood, and bulging fender flares. The changes made to the truck body, and the resulting improvements in air flow, add up to a quieter cabin for you and your passengers. Plus, its new hydraulic body mounts help mitigate vibrations to give you a smoother and more comfortable ride. The seats utilize a new design for lasting comfort, and reduced fatigue. On select models, the instrument panel incorporates a high-end soft feel, combined with trim made of aluminum for an overall look that is very stylish. The instrument panel has been laid out in such a way that your controls are now easier to get to and see, with larger buttons and knobs, which are more convenient to grab. Spoil yourself with the available 8-inch IntelliLink touch-screen system that you can opt for on SLE and SLT trims. It lets you control your radio and make calls hands-free, wirelessly stream music from your phone, use the rear view camera, and operate the navigation system. Sierra 1500 comes with a choice of 3 powerful engines, a 4.3L V6 EcoTech3 Engine with 285hp, a 5.3L V8 with 355hp, and a 6.2L V8 with 420hp.
