Redesigned for 2014, the 2014 GMC Sierra 1500 is fully competitive with its long-time and similarly capable rivals; this is especially true now that GMC offers a V6 engine that promises ample performance along with good fuel economy.
This Sierra features a 4.3-liter V6 with 285 hp and 305 lb-ft of torque and comes matched to a six-speed automatic transmission. GMC estimates fuel economy to be 20 mpg combined (18 mpg city/24 mpg highway).
The 2014 GMC Sierra 1500's new V6 provides ample thrust and is light-years ahead of the old V6, not only in terms of power and performance but also refinement. The six-speed automatic provides smooth and timely gear changes. The Sierra feels robust structurally, and yet compliant and comfortable over broken pavement. The 2014 Sierra is also very quiet, with road noise snuffed out and only a whisper of wind noise at freeway speeds. The GMC is also steady around turns, and its steering is well-weighted. Off road, the Sierra shudders less when bouncing around on rocky trails, exhibiting better composure than ever before.
With this redesign, all-new cab structures bring improved structural stiffness and crashworthiness to the 2014 model. GMC also improved the cabin quality, on which materials and build quality are noticeably better. Gone are the awkward reverse-opening rear doors of the previous extended cab, as the newly minted double cab has traditional forward-hinged doors that make it much easier to get in and out of the backseat. The new cabin also rides on improved body mounts for reduced noise and vibration, while clambering into the bed is made easier by clever steps and handholds built into each rear corner.
Standard safety features on the Sierra include antilock disc brakes, traction and stability control (with trailer sway control), front and rear seat side airbags and side curtain airbags. In government crash tests the 2014 GMC Sierra earned a five-star rating overall with five stars for frontal and side crash and four stars for rollover tests.
