2025 GMC Sierra HD AT4 Spied Release Date & Price. The upcoming 2024 GMC Sierra HD AT4 has actually been spied for the first time. What’s fascinating about this batch of spy shots is that the AT4 treatment uses a luxury Denali package. This looks like a fatal combination, for a range of factors.
The current Sierra HD AT4 is still behind more popular competitors such as Ram HD Power Wagon or Ford Super Duty Tremor. For that reason, blending off-road-oriented AT4 with a premium Denali trim level sounds like an affordable thing to do. Without further ado, let’s see what this exciting model has to provide.
GMC Sierra HD AT4 Spy Shots
The new 2024 GMC Sierra HD AT4 will present a couple of intriguing upgrades. Spy shots are currently here and the prototype model has actually been identified wearing the high-end Denali plan. Generally, this treatment on the AT4 variant consists of lots of chrome accents and enhanced styling. The front fascia features distinct grille inserts, horizontal slats, and a recognizable GMC badge.
The headlamps are more upright, and the AT4 model comes with red tow hooks. The side profile will consist of a new wheel design. The spy shots are revealing 18-inch wheels with Goodyear Wrangler tires. 20-inch rims will be available as a choice. The running boards are likewise using chrome materials and Sierra HD AT4 will provide Rancho shocks, together with the improved off-road suspension.
Two Powertrain Options
In terms of performance, the new 2024 GMC Sierra HD AT4 might acquire possible powertrain updates. Still, the current engine lineup will stay. Everything begins with a 6.6-liter V8 gas engine. This system supplies 401 hp and 464 lb-ft of torque. A 6.6-liter turbodiesel V8 engine is optional and it develops 445 horsepower and a torque of 910 lb-ft of torque. Rumored engine updates are stating that the optional Duramax diesel motor will gain more torque.
Currently, Sierra HD AT4 has an optimum towing capability of 36,000 pounds. This rating could be even higher in the future. The customers can select in between a 6-speed automatic and a 10-speed automatic transmission. Unlike other trim levels, the AT4 includes a locking rear differential, two-speed transfer case, and GMC’s Traction Select system.
Interior Changes
The cabin of the new Sierra HD truck will include more upright materials. The very same is with the interior of the 2024 GMC Sierra HD AT4. Reportedly, the upper trim levels will benefit the most. Unfortunately, the spy photos are not showing interior information. Nevertheless, this mix of the AT4 and Denali trim levels is more than appealing.
This could potentially suggest that the AT4 variation will be more superior than ever before. On the other hand, a more premium interior indicates a greater starting price. At this moment, all we can do is anticipate, so we’ll wait on the manufacturer to reveal official interior upgrades.
