2024 GMC Sierra HD AT4 Redesign and Specs. The upcoming 2024 GMC Sierra HD AT4 has actually been spied for the very first time. What’s intriguing about this batch of spy shots is that the AT4 treatment uses a luxury Denali package. This looks like a fatal mix, for a range of reasons.
The existing Sierra HD AT4 is still behind more popular rivals such as Ram HD Power Wagon or Ford Super Duty Tremor. For that reason, mixing off-road-oriented AT4 with a premium Denali trim level sounds like a sensible thing to do. Without additional ado, let’s see what this amazing model has to provide.
In terms of performance, the new 2024 GMC Sierra HD AT4 could acquire possible powertrain updates. Still, the existing engine lineup will stay. Everything starts with a 6.6-liter V8 gasoline engine. This unit offers 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 saying that the optional Duramax diesel motor will acquire more torque.
Presently, Sierra HD AT4 has an optimum towing capacity of 36,000 pounds. This score could be even greater in the future. The clients can select in between a 6-speed automatic and a 10-speed automatic transmission. Unlike other trim levels, the AT4 consists of a locking rear differential, two-speed transfer case, and GMC’s Traction Select system.

The new 2024 GMC Sierra HD AT4 will introduce a number of fascinating upgrades. Spy shots are currently here and the prototype design has been found wearing the luxury Denali bundle. Essentially, this treatment on the AT4 variation includes lots of chrome accents and improved styling. The front fascia comes with special grille inserts, horizontal slats, and an identifiable GMC badge.
The headlamps are more upright, and the AT4 model comes with red tow hooks. The side profile will consist of a brand-new wheel design. The spy shots are showing 18-inch wheels with Goodyear Wrangler tires. 20-inch rims will be offered as an option. The running boards are also wearing chrome products and Sierra HD AT4 will provide Rancho shocks, together with the improved off-road suspension.
The cabin of the new Sierra HD truck will consist of more upright products. The same is with the interior of the 2024 GMC Sierra HD AT4. Apparently, the upper trim levels will benefit the most. Sadly, the spy pictures are not showing interior information. However, this mix of the AT4 and Denali trim levels is more than appealing.

This could possibly imply that the AT4 version will be more superior than ever before. On the other hand, a more exceptional interior means a greater starting price. At this moment, all we can do is predict, so we’ll wait for the producer to reveal main interior upgrades.
