2024 GMC 3500HD AT4

This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued...

2024 GMC Sierra 3500 review: Our expert's take

By Aaron Bragman

Competes with: Chevrolet Silverado 2500/3500, Ford Super Duty, Ram 2500/3500

Looks like: A lightly restyled version of the outgoing Sierra 2500/3500

Drivetrains: 401-horsepower, 6.6-liter V-8 or optional 470-hp, turbo-diesel 6.6-liter V-8; standard 10-speed Allison transmission; optional four-wheel drive

Hits dealerships: Early 2023

It seems to be the season for updating the big heavy-duty pickup trucks because hot on the heels of a revamped 2023 Ford Super Duty and the debut of the 2023 Ram 2500 Heavy Duty Rebel, we now have news for the GMC Sierra 2500/3500 pickups. The brand has unveiled its refreshed 2024 models, which feature some mild styling updates, new interiors, upgraded engine power, a host of new trailering features and two new trims designed to boost the truck’s appeal (and sticker price): the Denali Ultimate and AT4X.

Big Truck Looks

Big truck owners like big truck looks, and the new Sierra HD won’t disappoint. Present for the new model year are revised front ends with new headlights, grilles, bumpers and trim, and trim levels are the Pro, SLE, SLT, AT4, AT4X, Denali and Denali Ultimate.

As is becoming a common feature on a lot of new GM vehicles, new lighting animation happens when approaching or starting the truck or using the turn signals. There are some new wheel designs for SLE, AT4, and Denali, plus larger 18-inch polished-aluminum wheels available on dual-rear-wheel 3500 models — and if you like, you can even specify new 22-inch accessory wheels for extra bling. The Sierra HD also has six new exterior color choices (for extra money, of course): Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic and Downpour Metallic. Finally, rear wheelhouse liners will be standard equipment on the Denali and Denali Ultimate dually models.
