Class-leading interior; vastly improved steering and handling; technology tops rival pickups
Styling is a little too similar to last year's truck
Despite a full redesign last year, the 2015 Sierra offers a few new updates, including a new OnStar system with a 4G LTE Wi-Fi hotspot and GM's impressive Magnetic Ride Control system for the upscale Sierra Denali.
Assuming that you pick the model that works for your lifestyle, you can't go wrong with any 2015 Sierra. With that said, we don't suggest the base-level Sierra if you're the kind of driver who enjoys gadgets, and we don't suggest the Denali if you're going to visit dirty job sites or rutted country roads. Our dream Sierra is probably a Sierra SLT or a well-equipped Sierra SLE -- though we certainly wouldn't turn down the Sierra Denali if we had the cash. Find a GMC Sierra for sale
Like all full-size pickups (and its Silverado sibling), the Sierra comes with a wide array of choices that include bed size and cab preference, drivetrain, engine, and trim level. We've simplified things and organized the truck's features by trim level, but choosing the right Sierra for you will likely involve more than simply picking a trim.
If you go with a base-level Sierra ($27,500), you'll be stuck, as you might expect, with the basics. That means power locks, cruise control, air conditioning and an AM/FM stereo -- but no simple conveniences such as keyless entry or power windows. With that said, base-level Sierra models do include a USB port and an auxiliary jack.
Next up is the SLE ($33,900), which adds all the base model's missing luxuries (keyless entry, power windows, SiriusXM satellite radio, a CD player) and a few more goodies. Such items include GMC's IntelliLink infotainment system, a backup camera, LED lighting in the bed, and a few miscellaneous appearance items.
Next up is the Sierra SLT ($41,200), which is offered only as a double cab or crew cab pickup. The SLT offers a long list of standard features, including leather upholstery, dual power front seats, heated mirrors and a locking rear differential. SLT models also come standard with the Sierra's 5.3-liter V8, while base and SLE models offer it as an option.
Topping the Sierra lineup is the Denali ($50,700), which only comes in crew cab form and includes the pickup's 6.2-liter V8 engine as standard equipment. Denali models include a long list of standard features, from chrome accents and leather seats to a heated steering wheel and an upscale Bose surround sound system.
As for options, the Sierra has several. Extras include a power sunroof, a navigation system, cooled seats, power adjustable pedals, and 4-wheel drive. Additionally, drivers can add safety features such as forward-collision alert and a lane-departure warning system.

Ford F-150 -- The all-new Ford F-150 is close competition for the Sierra and Silverado, boasting excellent fuel economy, high-strength towing and payload capacities, and a heavily modernized interior.
RAM 1500 -- Formerly the Dodge RAM, the RAM 1500 offers available air suspension and famous HEMI V8 power. There's still no other light-duty pickup with an available diesel engine.
Toyota Tundra -- The Tundra is refined and muscular, offering a strong rival to the Sierra, but the Tundra still can't trump the Sierra's wide range of bed, cab, and engine configurations.
