AEV Edition Sierra HD

Trucks are the new muscle cars. In this era, it’s all about the biggest, baddest four-wheel-drive pickup that can do it all. Whether it’s towing, hauling, racing, off-roading, or camping, there’s a truck for it. 

GMC have just thrown its hat into a whole new ring with the Sierra HD AT4X and Extreme AEV Edition. The 2024 Sierra HD AT4X is a 2500 HD truck with large capabilities, and the Extreme AEV Edition adds even more off-road usability without sacrificing its on-road duties. 

Very Heavy Duty

Starting with the first-ever Sierra HD AT4X, you get 18,500 lbs of towing capacity, a 1.5-inch suspension lift from the factory, multimatic dampers, a rear e-locking differential, 35-inch Goodyear Territory tires, special front upper and lower control arms with specific steering knuckles, new, larger steel transfer case skid plate with front aluminum skid plate, one-off Obsidian Rush interior with massaging and full-leather seats. 

AEV Edition – Even Wilder

If you decide to take your HD AT4X Sierra off-roading, you’ll be able to use the new Off-Road Mode, which will change various things on the fly, such as throttle sensitivity, the shifts from the transmission, the ABS brakes, as well as the traction and stability control. All of these changes in vehicle calibration will assist in making the truck easier for the driver to handle and operate in various off-roading situations and conditions. 

Going with the new AEV Edition Sierra HD will add stamped steel bumpers with built-in recovery points and a front winch, plus more steel skid plates under the vehicle to ensure your undercarriage will be safer when going off-roading. The AEV Edition also gets specific 18-inch Salta wheels and special exterior badges along with unique interior designs. 

Diesel or Gas?

Whether you buy an AT4X or AEV Edition Sierra HD, you can choose from a 6.6-liter V8 gasoline engine that makes 401 horsepower and 464 lb-ft of torque, or the tried and true 6.6-liter Duramax diesel that has been upgraded for 2024 to put out a whopping 470 horsepower and 975 lb-ft of torque. Both engines are mated to an Allison 10-speed automatic transmission. 

Both Sierra AT4X models will receive a tablet-style 13.4-inch infotainment touchscreen display with a 12.3-inch digital instrument cluster, a 15-inch head-up display, and a 12-speaker Bose sound system. 

Both models will be available later this fall, and whether you would like to order or get more information about the Sierra HD AT4X, AEV Edition, or any other GMC, Ewing Buick GMC will help take care of you.
