2024 GMC Yukon Configurations: Trims, Engines, and Options Explained

The 2024 GMC Yukon is a full-size SUV offered in multiple trim levels, each bundling different features, powertrains, and capability packages. Understanding how GMC structures these configurations helps you compare what you're actually getting — and where the meaningful differences lie.

How GMC Structures the 2024 Yukon Lineup

GMC offers the Yukon in two body styles: the standard-wheelbase Yukon and the Yukon XL, which adds about a foot of length for increased third-row and cargo space. Both body styles share the same trim ladder, so the configuration choices below apply to either version.

The 2024 Yukon trim levels, from base to top, are:

Each step up the ladder adds content — but also adds cost. The jump from SLE to SLT is meaningful; the jump from Denali to Denali Ultimate is about refinement and premium materials.

2024 Yukon Engine and Drivetrain Options

Three powertrains are available across the lineup, though not every engine is offered on every trim:

5.3L V8 (EcoTec3) The standard engine on most trims. It produces around 355 horsepower and 383 lb-ft of torque. It uses cylinder deactivation to improve fuel economy at highway speeds, though real-world MPG varies depending on load, driving style, and drivetrain choice.

6.2L V8 (EcoTec3) Available on higher trims, this engine produces approximately 420 horsepower and 460 lb-ft of torque. It's paired with a 10-speed automatic transmission and is the choice for buyers who want more towing capability or performance.

3.0L Duramax Inline-6 Diesel Available on select trims, this diesel engine trades outright power for efficiency and low-end torque. It's tuned for highway fuel economy and long-distance towing over extended mileage. Buyers in states with stricter diesel emissions regulations should verify availability and compliance.

Drivetrain choices include rear-wheel drive (RWD) and four-wheel drive (4WD). The AT4 comes standard with 4WD. The 4WD system on most Yukon trims uses an automatic transfer case, meaning the truck manages power distribution without requiring manual input.

Trim-by-Trim Breakdown

SLE

The entry point. Expect standard safety tech, a touchscreen infotainment system, and basic comfort features. It's functional, but more spartan than mid-range trims. Most buyers stepping up from a mid-size SUV or older Yukon will notice what's missing rather than what's present.

SLT

Adds leather seating, additional driver assistance features, a power liftgate, and more audio/connectivity upgrades. This is often where the value-per-dollar argument is strongest — the gap between SLE and SLT is significant in everyday usability.

AT4 🛞

GMC's off-road-focused trim. It adds a 2-inch factory lift, skid plates, MultiPro tailgate compatibility on applicable configurations, and an off-road suspension tune. It uses a 6.2L V8 by default on some configurations. Buyers who primarily drive on pavement get the rugged aesthetic but may find ride characteristics slightly firmer.

Denali

The luxury-oriented trim. Features include the 6.2L V8 as standard, a 10.2-inch infotainment display, a premium Bose audio system, magnetic ride control suspension, and more premium interior materials. The Denali badge carries significant resale recognition in the used market.

Denali Ultimate

The top configuration. It layers in additional interior materials (massaging seats, open-pore wood trim, exclusive color options), enhanced camera systems, and the Super Cruise hands-free highway driving assist feature — a system that uses a combination of lidar map data, cameras, and driver attention monitoring.

Key Option Packages to Know

Within each trim, GMC offers standalone packages that can blur the lines between levels:

• Luxury Package (on SLT): Adds features that approach Denali territory in interior comfort
• Max Trailering Package: Increases tow rating by upgrading the hitch, adding a transmission cooler, and recalibrating the system — not all configurations include this by default
• 3-Zone Climate Control: Available across several trims, controls temperature independently by row
• Panoramic Sunroof: Optional on multiple trims

What Shapes the Right Configuration Choice

Several factors determine which configuration actually makes sense for a given buyer:

• Towing needs: The 6.2L V8 with the Max Trailering Package reaches the Yukon's highest-rated tow capacity (around 8,400 lbs depending on configuration); the base 5.3L and diesel have lower ratings
• Fuel type access: The diesel option may not be available in all markets
• Seating vs. cargo trade-off: The XL body adds meaningful third-row legroom and cargo capacity, but also adds length that affects parking in urban environments
• Budget for options vs. trim level: Sometimes a lower trim with added packages costs more than the next trim up — or less, depending on what you actually need

The Piece That's Always Missing

The 2024 Yukon lineup is well-documented, but which configuration makes sense depends entirely on how you'll use the vehicle — towing frequency, passenger load, terrain, fuel costs in your area, and what you're willing to spend over the ownership period. Those variables sit with you, not with the spec sheet. 🔍
