Part of what makes the GMC Sierra 1500 an all-timer of a pickup truck is its illustrious history. It is a legacy on par with the likes of the Ford F-150 and the Chevrolet Silverado; the latter being a model the Sierra 1500 is based on. Together with the Silverado, the GMC took the world by storm and forever changed the landscape of the pickup truck segment.

The Sierra was introduced by GMC in 1962, but it was not as the standalone pickup truck we know it as today. It was unveiled as model variants for the company's C and K series pickup trucks, with the latter being available as half, three-quarter, and one-ton trucks that could be had in Sierra, Sierra Grande, High Sierra, and Sierra Classic trims. They were produced in parallel with the Silverado, with General Motors introducing a brand-new body for the second generation in 1967 to evolve it from just being a hauler. Thanks to this upgrade, the C/K became one of the very first multipurpose pickup trucks in history.

The third generation of the iconic truck was introduced in 1973. This model marked a drastic change for the vehicle, with its makers increasing its size to make it more like their sedans and introducing a bunch of family-friendly features. GM went all in on the third generation, even putting the pickup truck through wind tunnel testing to improve fuel economy. The model soldiered on until 1991, where it was replaced by its successor and the vehicle we would come to know as the current GMC Sierra, with the Chevrolet variant officially getting the C/K name. From then on, it was only onwards and upwards for the vehicle, as it established itself as a household name, evolved further to do virtually anything, and carving out a special place in automotive folklore. These days, Ford has some stiff competition from GMC and its Sierras, and it is the kind of rivalry that is making them sweat.

Over the years, the GMC Sierra 1500 strived to remain the rugged and incredibly capable pickup truck it was at the start of its life. While that has remained constant for decades, what underwent changes over the years is its design. Indeed, like every great vehicle does, it kept up with the times and adapted its design language to remain relevant and modern.

The Sierra 1500 began life with a truck chassis, but it was clear from the start that General Motors wanted it to be a trendsetter for the future. As such, they tried their best to incorporate features from the other sedans in their lineup. Minor tweaks followed for the rest of the first generation's life, before a significant overhaul followed for the second generation model. This one came with the same frame, but its chassis was redesigned from scratch to make it less of a hauler and more of a well-rounded vehicle.

The third generation of the Sierra marked a transition into a new kind of vehicle. As the 1970s rolled up, practicality was the name of the game, thanks to a combination of changing demands and a fuel crisis. As such, General Motors responded by making it a much bigger vehicle than before, coupled with a more luxurious and premium interior that put it on par with family sedans. This allowed the Sierra to serve as an alternative for those who wanted a family car, but were also keen on a bigger ride.

General Motors used computers to design this version of the Sierra, which marked a first time for the segment. Thanks to this venture, the eventual design was also extremely aerodynamic compared to those before it. This allowed the truck to become way more fuel-efficient than its predecessors and lay the groundwork for the multifaceted fourth generation. Chevrolet and GM finally joined the Ford-Dodge party for extended cabs, bringing out one of their own for the newest model. This generation saw design tweaks for specialized models, including the work (W/T 1500), super performance (454SS), commercial (C3500HD chassis cab), and off-road (Z71) versions.

For a machine that looks as imposing as the GMC Sierra 1500, it would have been a shame for it to come packing minimal power. Thankfully, the good folks at GMC were only happy to give it the grunt it deserved. At the very beginning of its existence, it came with a 305 cubic-inch V6 that put out 150 horsepower. This was more powerful than the power unit the Chevrolet versions of the C/K came with, and both were less powerful than the Sierra's optional 283 cubic-inch V8 that delivered 10 extra horses. The second generation carried over the same power units, only discarding them for the Chevy ones towards the end of its life.

The third generation of the Sierra was the model with the biggest life span. As such, it came with all kinds of V6 and V8 engines throughout this time, even a humongous 7.4-liter V8 and the classic Oldsmobile 5.7-liter V8. This endeared the truck to fans even more and kept it fresh and relevant, with even the next generation using the same powertrains. The present-day Sierra 1500s are powered by a 2.7-liter turbocharged engine, a 3.0-liter Duramax diesel engine, or a 5.7-liter V8 that is the most powerful of the lot. Some models even come with a 6.2-liter V8.

The outgoing model of the Sierra 1500 is designed from the lessons taught by its ancestors. Thanks to the pickup truck segment focusing on aerodynamics, luxury, and practicality more than ever, GMC has duly adapted. That relentless pursuit of perfection has resulted in a truck that is simply one of the benchmarks of its class and a compelling alternative to the popular Ford F-150, a vehicle often considered the face of the segment. Some of the tech it comes with includes its Super Cruise hands-free driver assistance technology, multiple safety aids, towing-assistance technologies, a premium Bose sound system, a fantastic infotainment system that is compatible with Android Auto and Apple CarPlay, some lavish seat-massaging, and much more. Indeed, the very first Sierra would be proud of how far it has come.

While every GMC Sierra 1500 is a phenomenal investment, its special editions are worth every penny. There is the Sierra 1500 AEV Edition, which is an off-road and adventure specialist truck that is more capable than the standard models. And from a design perspective, trucks do not come cleaner than the Sierra 1500 Graphite Edition, which comes in a very aesthetic black-and-white color scheme.
