GMC released the Sierra AT4 in 2018 as a leading competitor for the reigning Ford F150, but not any 150; the Raptor version.
The half-ton pickup-trucks were often used for off-roading situations, and the carmakers made them more and more capable of getting in the middle of nowhere and back without too much fuss. But in the end, it all comes to the ground clearance, tires, power, and traction. When any of these is gone, the others can’t do anything. GMC tried to solve as many problems as possible, giving more power, more traction, and better ground clearance to the Sierra in the AT4 form.

The first noticeable difference between an AT4 and a regular Sierra was the height. With a 2” lift kit fitted as standard, the AT4 was taller and thus appeared more impressive on the road. At the front, the big headlights and the black grille dominated the roads ahead. Unlike its siblings, it featured two red tow-hooks at the front. On its sides, the plastic moldings inside the wheel-wells made the gap seems smaller, but it was tall enough to put a six-pack on the wheel without any trouble.

The interior was fit for an overnight stay if stranded in the woods. It was wide, spacious, and could fit up to five people, but only two could sleep well on the wide front seats, separated by a center console, wide enough to serve as a nightstand. GMC installed a color head-up display for the driver and a rear camera mirror.

GMC offered the Sierra AT4 with a standard 5.3-liter V8 engine, while a 6.2-liter V8 and a 3.0-liter turbo-diesel were offered as an option. For better traction, the carmaker installed a standard rear differential lock and a two-speed transfer case.

There was a time when pick-up trucks were just pick-up trucks, with no convenience features and a rudimentary interior design.
The GMC Sierra Denali is just an example of how things evolved along the time, being one of the most luxurious pick-up trucks on the market.

For 2019, the Denali featured lots of innovative features to provide maximum practicality and comfort.

The luxurious pick-up truck featured the most innovative tailgate in the automotive industry. The lower part of it came down and served as a step, the little step could also be used as a cargo stopped if folded up and the top half could be lowered and added to the step, turning into an increased cargo stopper. And this was no hard thing to do, the tailgate featuring 2 buttons for easy actioning.

At the front, the Denali was just massive, with a huge chrome grille and fog lights the size of a smaller car’s headlamp.

Inside, the Denali offered multiple storage spaces and even two separate gloveboxes. The interior mirror was highly functional, offering a much wider view of what was behind using the rear view camera instead the obstructed real image, and a car the size of a Denali was much easier to manoeuver.

All the controls were intuitively placed and easy to use, drivers could choose the preferred driving mode by switching between Tour, Sport, Off Road and Tow/Haul. Other features included heated seats, heated backrests, cooled seats, 2 USB ports and a regular household and even a huge head-up display. While in the off-road setting, the system displayed even the vehicle’s angle, offering a proper experience and enhanced safety.

Besides the usual information about the vehicle’s state, with the Denali, the drivers could also see the air filter life and the brake pads life in percentage.

The all-new 2014 GMC Sierra 1500 full-size pickup is the most powerful, most advanced and most refined truck in the brand’s 110-year history.
GMC Sierra’s bold new exterior houses one of three all-new EcoTec3 engines, a fully updated cabin with available next-generation IntelliLink connectivity and other features designed for the most discerning truck owners. Premium materials, attention to detail and purposeful technology define GMC Sierra’s all-new cabin. New soft-touch materials and available aluminum trim line an interior that’s focused on usable and productive space. For the first time on Extended Cab models, the 2014 Sierra has new front-hinged rear doors with outside pull handles at the rear, providing improved access in tight parking spaces. Unlike trucks with rear-hinged doors, Sierra’s layout allows rear passengers to enter and exit the vehicle with the front doors remaining closed. A suite of active safety features will be optional for the 2014 Sierra, including Forward Collision Alert, which uses a forward-facing camera to notify the driver of an imminent collision, and Lane Departure Warning, which uses the same camera to track the truck’s position in relation to a road’s lane markers.

The 2008 GMC Sierra came on the market during the world financial crisis’s harsh times in three body shapes, and the most convenient dual-use vehicle was the 1500 Crew Cab.
GMC was no rookie on the pickup game since it built vehicles for over a century and its specialty was on the utility-vehicles segment. The Sierra was already on its third generation, and thanks to its crew-cab version, it was a good choice for those who needed a truck for work and an outdoor vehicle for the weekend with their families. It was built on the T900 platform, which proved to be much better than the one it replaced it.

Like its predecessor, the Sierra was available in a few body versions, starting with a chassis-cab and going up to the big crew-cab version. Its raked windshield at 57 degrees decreased the wind noise and the aerodynamic resistance, increasing the fuel-efficiency. To add a more dynamic appearance, the Sierra featured flared wheel-arches. For the Crew Cab version, GMC offered the Sierra with a few bed length options, depending on the owner’s needs.

Inside, the Sierra offered room for up to five passengers. Thanks to the new platform, the carmaker was able to build a flatter floor in the rear. That led to an increase in legroom for those sitting on the bench. At the front, the driver and its passenger enjoyed a big dashboard with a flat front side and a center stack for the climate-control unit and the audio/infotainment system, depending on the options.

The manufacturer offered the Sierra with a choice of four engines paired as standard to a 4-speed automatic gearbox. It was available either as a 2WD or 4WD.

The third generation of the Sierra was introduced in 2006 as a 2007 model, and the light-duty trucks appeared on the market in 2006.
With over a century of experience on the market, GMC Trucks already knew what its customers want from their pickup-trucks. Even though it couldn’t beat the Ford in the sales figures, that didn’t mean that there was something wrong with the way the vehicle was built. It was more like the way the vehicle was priced. The T900 platform offered better solutions and more powerful engines than its predecessor, the T800.

Its raked windshield at 57 degrees decreased the wind noise and the aerodynamic resistance, increasing the fuel-efficiency. To add a more dynamic appearance, the Sierra featured flared wheel-arches. For the Extended Cab version, it featured a pair of doors at the front and sway doors in the back. The bed in the back was available in three sizes of 5.75’ (1752 mm), 6.5’ (1981 mm), and 8’ (2438 mm) on three different wheelbases.

Inside, the GMC Sierra offered up to five seating positions, with enough room for the front occupants and decent sized for the rear ones. Like most of the pickup-trucks on the market, it offered a big dashboard, with a steering-column mounted gear-selector for the automatic transmission.

GMC introduced the third generation of the Sierra in 2006 and, a year later, it introduced the regular-cab option, which was not aimed only for workers.
