After a full redesign last year, the GMC Sierra 1500 returns for 2020 with several notable updates. The Carbon fiber bed option is now available across more trim levels as is the 3.0L Duramax diesel engine. The biggest new feature for 2020 is the addition of a "transparent trailer" view which uses cameras to simulate the view to the rear as if the trailer were not there.

The 2019 GMC Sierra 1500 rests upon an entirely new platform this year. It's longer, has more interior space, and shows off a handsome exterior facelift that further differentiates itself in a meaningful way from its counter-part the Chevy Silverado. Exclusive features include adaptive dampeners, a split folding tailgate, a carbon fiber cargo box, and C-shaped lighting elements to name just a few. The Crew cabs longer wheelbase makes way for 3 more inches of leg room in the back seat. All trims are built on a lighter frame and suspension components with aluminum hood and door panels saves 360 pounds over its predecessor. Also new for 2019 is Dynamic Fuel Management, which is designed to fine-tune the balance between efficiency and power demand. It lets the engine operate anywhere between two and eight cylinders depending on load.

The GMC Sierra returns in 2018 without a lot of changes. The base model now gets a nicer radio with a 7-inch color touch screen and a rearview camera, while the tire pressure monitoring system has also been improved

For 2017, the GMC Sierra 1500 features several minor updates. Among them is a new capless fuel filler system, along with low-speed mitigation braking as part of the Enhanced Driver Alert Package.

The Sierra hasn't been completely redesigned for 2016, but it does get major upgrades for this year. Styling has been improved through a brand new grill and front fascia along with new taillights at the back. Beyond the exterior changes, the Sierra also gets a host of new electronic infotainment features including a brand new 7-inch touchscreen, increased connectivity and functionality for Apple devices and wireless phone charging. New options for 2016 include power articulating steps to help ingress and egress, a remote locking tailgate, a driver alert package and an 8-inch touchscreen.

Following its redesign last year, the 2015 GMC Sierra 1500 has a variety of updates. As in other GM models, the newest OnStar system debuts, complete with 4G LTE WiFi connectivity. A spray-on bed liner is now available, and HD radio has been removed from all Sierras. A new eight-speed transmission is now standard on trucks equipped with the 6.2L EcoTec3 V8.

The GMC Sierra 1500 has been completely redesigned for 2014. Like the Chevrolet Silverado 1500, with which it's very closely related, the Sierra gets new V6 and V8 engine options that are both stronger and more economical than before. A new design for the double cab allows for better rear-seat entry and exit. IntelliLink connectivity and infotainment systems have been upgraded and a new look inside and out, with much-improved interior appointments.

The GMC Sierra 1500 is unchanged for 2013 with the exception of a minor update to the transmission. The automatic gearbox will now use the engine to assist with braking on hill descents even in normal mode.

Subtle redesigned front bumper and grille show up for 2012 and The Denali models get standard heated and cooled seats and a heated steering wheel.

The GMC Sierra 1500 full-size pickup receives no notable changes for 2011.

The GMC Sierra 1500 was last redesigned in 2007, and there are few changes for the 2010 model year. Over 30 combinations of engines, beds and other items are available. Except for the V6 engines, all 2010 Sierra engines are now Flex-Fuel capable, meaning they can run on gasoline or E85 ethanol. A 6-speed automatic transmission is standard on all but the base trims. StabiliTrak is now standard on all trims, as is a USB media player port.

The GMC Sierra sees some important changes for 2009, including the availability of a new gas/electric hybrid model, as well as a new 6.2L Vortec V8 engine, which can run on E85 ethanol-blended fuel. Also new for that engine, is a 6-speed automatic transmission, XM satellite radio, Bluetooth hands-free connectivity and a rearview camera system. The 4-speed super-duty transmission has been deleted, as have the paint colors Dark Blue Metallic and Desert Brown Metallic. New standard features on SLT models include a rear locking differential, trailer package and remote start. StabiliTrak stability control is now only available on V8 model Sierras.

The GMC Sierra 1500, which was completely redesigned a year ago, sees little variation for the 2008 model year. The color palate has a few new choices, six-way power seat adjusters are available on SLE trim, and satellite radio is standard across the board. The uplevel LTZ trim no longer includes a universal home remote or rain-sensing windshield wipers.

The GMC Sierra 1500 has been completely redesigned for 2007, with more attention to interior appointments, luxury features, and driving refinement. Like its forbears, the new Sierra is available in a wide range of combinations, determined from three different cab styles, three cargo box lengths, three trim levels, five suspensions, and various V6 and V8 engines. The new Sierra is built on a new fully boxed frame and has a wider track than the previous model for improved stability. A new coil-over-shock front suspension and a new rack-and-pinion steering unit improve ride and handling. StabiliTrak is available on the Sierra for the first time. Warranty coverage is increased for 2007, with five years or 100,000 miles of powertrain coverage that's fully transferable and includes roadside assistance for the full period. The former Sierra is still being sold for 2007 as the Sierra Classic, so some dealerships are referring to the new models by their factory designation, GMT900, to avoid confusion.
