The GMC Sierra 1500 is a full-size pickup truck made by General Motors that is mechanically identical to the Chevrolet Silverado; and has remained the same throughout their shared history. It has had a base V6 engine or an optional V8 through the years, with new models offering a turbocharged four-cylinder engine.
1999-2006 (1st Generation)
The Sierra 1500 was considered as the light-duty version of the Sierra, and was built on the GM GMT800 platform. It was available in three different cab lengths, including the two-door regular cab, the four-door extended cab and the front-hinged four-door crew cab, with cargo beds ranging from 69.2-inch short box, the 78.7-inch standard box and the 97.6-inch-long box.
The first year of this generation, only the regular cab and extended cab were offered, and engine options were the Vortec 4.3-liter V6, the 4.8-liter V8 and the 5.3-liter V8; and it was available in RWD or 4WD. Seating is available from three to six passengers.
In 2004, Sierra offered three cab styles, with the crew cab becoming available. It featured half-ton, three-quarter-ton and one-tone capacities; as well as 2WD or 4WD. An optional Quadra steer four-wheel steering was available.
The 2006 GMC Sierra 1500 has a long list of configuration choices and comes with a manual or automatic transmission.
2007-2013 (2nd Generation)
In the generation, the Sierra 1500 was built on the GMT900 platform, and the exterior, interior, frame and suspension were all redesigned.

It featured new 18- and 20-inch wheel designs, and V8 models get six-speed automatic transmission.

Another refresh happened in 2012 and this included a redesign of the touch-screen navigation system.
2014-2018 (3rd Generation)
In this generation, Sierra used aluminum in its construction, including on the hood, the engine block and suspension control arms to reduce weight and use less fuel. Boasting best in class trailering, the Sierra has been significantly updated with three new engines, while still being a true workhorse.
For 2015, Magnetic Ride Control for Sierra Denali models is available and a new eight-speed automatic transmission is also available; as well as all-wheel-drive. OnStar with 4G LTE and Wi-Fi hotspot capability is available.
