People use pickup trucks as everyday vehicles, even heavy-duty models, so it’s not surprising to see automakers adding more luxury and capability to their most work-ready models. Rugged, off-road-read heavy-duty trucks are nothing new, but GMC’s taking it to the next level with the new Sierra HD AT4X and Extreme AEV Edition trucks. The pair comes with a slew of upgrades to improve their off-road capability while maintaining the workhorse attitude that people expect from heavy-duty trucks.

The 2024 GMC Sierra HD AT4X gets a 6.6-liter gas V8 as standard, but buyers can add the 6.6-liter Duramax diesel. A ten-speed automatic transmission and four-wheel drive are standard. The truck delivers 18,500 pounds of towing, a 1.5-inch lift kit, Multimatic DSSV dampers, an electronic locking rear differential, and 35-inch Goodyear tires. The HD also gets a new off-road driving mode, which recalibrates braking, steering, and other settings to improve traction and performance.

The Extreme AEV Edition brings touches from American Expedition Vehicles, including 18-inch wheels and underbody steel skid plates. It also offers steep bumpers with integrated recovery points and a winch mounting point.

Both trucks bring the luxury inside, where GMC equipped leather upholstery and massaging front seats. Ash wood trim and a Bose 12-speaker premium stereo come standard, along with a 13.4-inch touchscreen and 12.3-inch digital gauge cluster. GMC offers several driver aids, but most are withheld in added-cost options package. Available tech includes a transparent trailer-view camera system, blind spot monitoring with trailer coverage, and adaptive cruise control with trailering.

GMC hasn’t detailed pricing for the new trucks yet but said more information would become available closer to their on-sale date this fall.

Sad fact is thats all that truck can safely tow. You need to spring for a 2500 or 3500 to actually tow a large travel trailer.

SilverCoupe Tim, you don't always watch F1 as you don't want to lose sleep? But these races are great for putting one to sleep!I kid (sort of). I DVR them, I watch them, I fast forward a lot. It was great to see Lando win one, I've been a fan of McLaren since their heyday in CanAm in the late '60's.
Cprescott The problem with this fable by the FTC is:(1) shipping of all kinds was hindered at ports because of COVID related issues;(2) The President shafted the Saudis by insulting them with a fist bump that torqued them off to no end;(3) Saudis announced unilateral production cuts repeatedly during this President's tenure even as he begged to get them to produce more;(4) We were told that we had record domestic production so that would have lowered prices due to increased supply(5) The President emptied the strategic petroleum reserve to the lowest point since the 1980's due to number 3 and then sold much of that to China.We have repeatedly been told that documents and emails are Russian disinformation so why now are we to believe this?

Kjhkjlhkjhkljh kljhjkhjklhkjh Who cares. Price of gas is not the issue. spending an extra 100$ a month over 4 tanks of gas is not the issue.this a political scam to distract really dumb people from the real issue. if rent and house payments were not up by 50% to as high as 150% higher in a ton of locations, then paying an extra 100$ in gas would be annoying but not really an issue. But the real-estate market with hedge fund investors, power-relator groups bought a ton of houses and flipped them into rentals and jacked up the rates uplifting the costs on everything else. and ironically no-one seems to be in any hurry to build more houses to bring those costs down because supply and demand means keeping less houses available to charge as much as you want. It is also not the issue as a secondary issue is child care costs and medical... again 100$ extra per month in gas is *nothing* compared to 800$ a month in ''child care'' and 300$ per visit to the doctor office, 300$ for a procedure less dentist trip..
