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.View GMC Sierra 1500 Double Cab vehicles for sale near you.

"Now that i outright OWN the 2015 GMC Sierra 2500HD Crew Cab (6.0L V8 Vortec) SLT 4x4 (Z71 Off-Road Suspension Pkg) i can relay some of my initial driving experience w/it as an owner instead of just test-driver. It gets better gas mileage than my old Jeep Cherokee V-6 2WD (both city/hwy mileage), so i can't kick. To all y'all that want better MPG's: you might best stick w/the ½ ton GMC Sierras w/Eco-Tec or Duramax engines (or whichever mfgr. brand you favor). As far as the "on-the-column" gear shifter (automatic transmission) - I didn't find mine to be "jerky" at all. My old vehicle had the on-the-console automatic shifter, & 1 before that had gear shift on the steering column. Same function but shifting on-column is NOT something you ram or slam into gear, you "slow & easy" position the shifter into proper gear otherwise "you overshot the mark" & need to re-position to correct. I checked the on-the column automatic transmission gear shift a bunch before I full-on bought mine- on account i read a review posted here that made mention of "jerky" shifting probs. Mine works just fine & IF it DIDN'T, I WOULD'T buy it. If it came up faultering after I bought it, oh boy!..you can bet I'd have it looked at, right QUICK, while under warranty. Mine shifts proper & to my liking. The truck itself is a champ! On the subject of off-road, well, I'm NOT "ditch jumpin" w/it but the 4WD (hi & lo) is just plain fine, IMO, for general all-terrain purposes. Haven't hauled "heavy" with it yet. I'm real pleased i opted to have the 20" FORGED polished aluminum GMC wheels instead of 18" alum. clad wheels! The factory spray-on bedliner is better than I expected. The paint around the very bottom of the chassis could've been finished better (I found one tiny 1/4 globule that formed a stray droplet along the very edge near the underside of the wheelhouse - slight "orange peel" where GM applies a protective undercoat beneath exterior paint color alongside to the lower left of where the assist steps normally are situate . This undercoating near bottom edge of chassis is resident on most all 4x4 Sierras I inspected while shopping, and was/is limited to the area near the rear wheel housings, drips or were visible more in some than others (i found that dealers are commonly blaming that on automated mechanical paint application). More on this in immediate follow-up."

"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."

"Drives great, quiet interior, good gas milage, plenty of power. still getting use to the longer bed 6.5 vs my 2012 gmc's 5'8 bed. Truck pushes a little bit more than my previous truck in the corners. Overall great truck! I would bet the truck could be a little cheaper on the sticker price if GMC wouldn't have so many commercials on TV!"
