The 2015 GMC Sierra gains a new 8-speed automatic transmission on models equipped with the 6.2-liter V8. The Denali gains GM's Magnetic Ride Control suspension, while Siri Eyes-Free and OnStar 4G LTE with built-in Wi-Fi hot spot is made available. A spray-in bedliner is also available on all models.
Thanks to a complete overhaul last year, the GMC Sierra pickup line for 2015 arrives just in time to do battle with latest Ford F-150, Ram 1500, Toyota Tundra and Nissan Titan. Although it shares much of its chassis and mechanicals with the Chevrolet Silverado, GMC stamps its own upscale brand on the Sierra, giving it the feel of a work truck for the boss rather than the crew. It is true that the basic Sierra work truck isn't all that plush, but move up the line to the Denali model and you'll find more leather and chrome than in a Texas rodeo gift shop. A choice of V6 or V8 engines is offered, as is a new 8-speed automatic transmission.

"Truck is stylish. Very quiet. Very little road noise. Pleasure to drive during the day. Has lots of nice features. HOWEVER, the headlights are absolutely terrible. Far too dim. Extremely hard to see on back roads. Wish I would a known this prior to purchase. Previous models have great LIGHTS. No excuse for this other other than poor engineering."

"Very quiet ride. Nice looking. Steps in rear bumper great idea. Sharp looking interior. Great gas mileage. 19.6 mpg on 2800 mile trip carrying 900 lbs cargo. Engineers overlooked some small but important things. Projector headlights are terrible, no peripheral lighting on hi beams, interior dome lighting is bad, outside temp reading doesn't update frequently enough, speakers in front doors stick out too far and get kicked when exiting, piping on leather seats is very irritating when exiting or entering frequently, no provision to turn off auto door locks, infotainment screen is too bright for night driving and cannot be dimmed independently from the dash lighting, interior is super quiet but I still have to listen to the key fob rattle against the steering column on uneven roads, side mirrors are too small and can't see rear wheels with them, steering wheel mounted controls are no longer at your fingertips but are now smaller and mounted higher up and can't be felt with gloves on. Less vision out windshield compared to previous model. I use this truck for work and a lot of times at night with entry and exit at least 50 times a day. This truck is not as convenient or comfortable as the previous model."

"Traded in a flawless GMC Duramax for this Sierra SLT with the 6.2 liter engine. It has less low end torque than the D-Max and took a bit of getting used to. The interior finish is superb and the ride is unlike any truck I have driven. The power of the 420HP L-86 engine leaves every other truck in the dust. The styling, although sedate, is still attractive. The exterior finish is absent the lousy 'orange peel' look so prevalent on the older GM trucks. I gave an excellent rating for most categories, but slightly lower for reliability as this is a first year model, however I have no issues to report. I have read about concerns over the headlight illumination and vibration issues, but I have not experienced either. I travelled up through Massachusetts and into New Hampshire last evening......75 MPH, solid on the road and great to drive!"
