2024 GMC Yukon Buyer’s Handbook: Engines, Towing, and Tech
You’re staring at the window sticker on a 2024 Yukon Denali, and the numbers don’t line up. One website says 355 horsepower. Another says 420. Your buddy swears the diesel gets 27 MPG. The salesman keeps saying “Super Cruise” like it’s magic. You just want to know: which engine actually fits your life, how much you can tow without melting the transmission, and whether the $100,000 Denali Ultimate is worth it or just a very expensive way to tell your neighbors you’ve made it.
TL;DR:
The 2024 GMC Yukon is the last of a dying breed—a body-on-frame, V8-powered, three-ton American SUV that still believes gasoline is a personality trait. It offers three engines, two wheelbases, and five trims spanning from $60k workhorse to $100k luxury barge . The 5.3L V8 is the sensible choice, the 6.2L V8 is the emotional choice, and the 3.0L Duramax diesel is the secret weapon that out-torques both V8s and returns 27 MPG highway . But here’s the catch: the diesel isn’t available on the off-road AT4 trim, and the 6.2L requires premium fuel and returns 16 MPG combined if you’re lucky . Towing maxes at 8,400 pounds—competitive, but Ford and Jeep both tow more . Super Cruise is still locked behind the Denali Ultimate’s Advanced Technology Package, adaptive cruise control is strangely optional, and the 2024 model is basically a 2023 with new OnStar subscriptions . This handbook cuts through the brochure-speak and tells you exactly which engine doesn’t justify its thirst, which trim is the actual value play, and why the Yukon XL might be the only one that makes sense if you have more than two kids.
Key Takeaways:
- Three engines, three distinct personalities. The 5.3L V8 (355 hp, 383 lb-ft) is the reliable workhorse, regular fuel, 8,400 lbs towing. The 6.2L V8 (420 hp, 460 lb-ft) is the hot rod, premium fuel, 16 MPG. The 3.0L Duramax I6 (277 hp, 460 lb-ft) is the highway champion, 27 MPG, same torque as the big V8 .
- The diesel is not available on AT4. If you want the off-road package with the fuel-sipping Duramax, GMC says no. AT4 buyers get the 5.3L standard or optional 6.2L .
- Towing peaks at 8,400 pounds. That’s with the 5.3L V8 and RWD. The diesel and 6.2L are slightly lower. Ford Expedition (9,300), Toyota Sequoia (9,520), and Jeep Wagoneer (10,000) all out-pull the Yukon .
- The Yukon XL is the cargo king. Standard Yukon: 25.5 cu-ft behind third row, 122.9 max. XL: 41.5/144.7. That’s class-leading .
- Super Cruise exists, but you have to hunt for it. Available only on Denali Ultimate via the Advanced Technology Package. It’s not standard, and adaptive cruise control still costs extra on lower trims .
- The 2024 model is a carryover year. No meaningful changes. OnStar packages were reshuffled. That’s it. If you find a 2023, it’s the same truck for less money .
- Fair Purchase Price is thousands below MSRP. Don’t pay sticker. Current average discounts range from $2,107 to $5,804 depending on trim .
The Engine Room: Choosing Your Poison
Let’s start under the hood, because this is where the Yukon separates itself from every unibody crossover pretending to be an SUV.
5.3L EcoTec3 V8 – The Gray Man
- 355 horsepower @ 5,600 RPM
- 383 lb-ft torque @ 4,100 RPM
- Regular fuel
- 17 MPG combined (RWD/4WD)
- Max towing: 8,400 lbs
- Standard on SLE, SLT, AT4
This is the engine that will run forever, drink regular, and never complain. It’s not exciting. It doesn’t make you grin when you merge onto the interstate. But it also doesn’t require premium fuel or apologize for its 5,600-pound curb weight. This is the smart buy .
6.2L EcoTec3 V8 – The Wallet Opener
- 420 horsepower @ 5,600 RPM
- 460 lb-ft torque @ 4,100 RPM
- Premium fuel required
- 16 MPG combined (4WD only on Denali Ultimate)
- Max towing: ~8,300 lbs
- Standard on Denali, Denali Ultimate; optional on AT4
This engine is objectively unnecessary and subjectively glorious. It moves 5,800 pounds of SUV to 60 mph in the mid-6-second range, sounds authoritative doing it, and empties your wallet at the pump with enthusiasm. You buy this because you want a V8, not because you need one .
3.0L Duramax Turbodiesel I6 – The Secret Weapon
- 277 horsepower @ 3,750 RPM
- 460 lb-ft torque @ 1,500 RPM
- Diesel fuel
- 27 MPG highway (RWD), 22-23 combined
- Max towing: ~8,200 lbs
- Available on SLE, SLT, Denali, Denali Ultimate
- NOT available on AT4
Here’s the part that confuses everyone: the diesel makes the exact same torque as the 6.2L V8, but it arrives at 1,500 RPM instead of 4,100. You don’t wind it up; you just breathe on the throttle and it pulls. It’s also the only way to crack 20+ MPG in a Yukon, and it tows nearly as much as the gas engines.
Interesting fact: The 3.0L Duramax is the only diesel engine available in a full-size, body-on-frame American SUV in 2024. Ford doesn’t offer one. Jeep doesn’t anymore. Toyota never did. It is, for now, alone .
The catch: You cannot get it with the AT4’s off-road package. GMC decided diesel buyers don’t want red tow hooks and skid plates. Their loss, your compromise.

Towing: The Numbers Don’t Lie, But They Also Don’t Impress
Let’s be honest: the Yukon’s towing capacity is adequate, not class-leading.
2024 GMC Yukon Max Towing:
- 8,400 lbs – 5.3L V8, RWD, standard wheelbase
- 8,300 lbs – 6.2L V8
- 8,200 lbs – 3.0L Duramax
- 7,400–8,300 lbs – Yukon XL (slightly lower across the board)
The competition:
- Ford Expedition: 9,300 lbs
- Toyota Sequoia: 9,520 lbs
- Jeep Wagoneer: 10,000 lbs
What this means: You can tow a 25-foot travel trailer, a boat, or a car hauler. You cannot tow a 30-foot Airstream or a triple-axle toy hauler without exceeding the Yukon’s limits. If you need max capacity, buy the Expedition.
What saves the Yukon: The ProGrade Trailering System. Available on most trims, it bundles:
- Hitch Guidance with Hitch View (backup camera alignment lines)
- In-vehicle trailering app (pre-trip checklists, trailer mileage tracking)
- Trailer Side Blind Zone Alert (extends blind spot monitoring to include your trailer)
“This is a must if you’ll be towing regularly.” — Kelley Blue Book .
Safety reminder: Maximum towing capacity requires the optional trailering package and proper weight distribution hitch. Your Yukon’s specific equipment determines its actual limit. Do not exceed the Gross Combined Weight Rating on your door jamb sticker.
The Trim Ladder: Five Steps, Two Directions
The 2024 Yukon lineup is five trims, two philosophies. You’re either buying a luxury wagon (SLE → SLT → Denali → Denali Ultimate) or an off-road pretender (AT4). Know which camp you belong to before you start negotiating.
SLE ($60,195 MSRP, $58,088 Fair Purchase Price)
Best for: Fleets, large families on a budget, people who think nine seats is a flex.
The SLE is the only trim that offers a front bench seat and 9-passenger capacity. It’s also the only trim without leather, without a power liftgate, and without blind-spot monitoring (optional). The 5.3L V8 is standard, the 13.4-inch screen is present, and the seats are cloth.
The verdict: Skip it. The SLT costs about $6,000 more and adds $15,000 worth of features you’ll immediately miss .
SLT ($66,895 MSRP, $62,339 Fair Purchase Price)
The value king.
This is where the Yukon stops feeling like a rental. Standard equipment includes:
- Leather-appointed seats (heated/ventilated front, heated outboard second row)
- Hands-free power liftgate
- Bose 9-speaker audio
- Blind Spot Monitoring with Rear Cross Traffic Alert
- Power-folding third row (optional)
- 20-inch wheels
You can also option the 3.0L Duramax diesel here. This is the smart money play. You get 90% of the Denali’s comfort for $15,000 less and 27 MPG highway .
AT4 ($73,500 MSRP, $70,927 Fair Purchase Price)
Best for: Suburbanites who want to look like they off-road.
The AT4 adds:
- 2-inch factory lift (via air suspension? conflicting sources—some say standard lift, others say optional)
- All-terrain tires
- Skid plate
- Red recovery hooks
- Hill Descent Control
- Unique grille and trim
The engine situation: Standard is the 5.3L V8. Optional is the 6.2L V8. Diesel is not available. This is the only Yukon trim that excludes the Duramax.
The verdict: If you actually take your SUV on fire roads, this is the one. If you just like the look, the SLT with aftermarket wheels is cheaper and rides better .
Denali ($78,800 MSRP, $73,725 Fair Purchase Price)
The sweet spot.
The Denali standardizes the 6.2L V8 and adds:
- Magnetic Ride Control
- 22-inch wheels
- Power-retractable assist steps
- Open-pore wood trim
- Head-up display
- 14-speaker Bose audio
This is where the Yukon legitimately competes with Lincoln and Cadillac. The interior materials are a genuine step up from the SLT, and the Magnetic Ride Control transforms the highway ride from “truck” to “luxury sedan” .
What you don’t get: Massaging seats, Super Cruise, or the etched wood trim. Those are Ultimate exclusives.
Denali Ultimate ($100,750 MSRP, $94,946 Fair Purchase Price)
The halo.
The Ultimate adds approximately $22,000 worth of exclusivity:
- Massaging front seats (16-way power)
- Full-grain leather with embossed topography map
- Paldao wood trim with laser-etched topographical map of Mount Denali
- Super Cruise with 3-year trial (Advanced Technology Package)
- Rear-seat entertainment system
- 22-inch wheels with laser-etched accents
- Unique Vader Chrome grille (not mentioned in 2024 KBB, but present in 2025; verify)
The question: Is it worth $100,000? Objectively, no. A Cadillac Escalade starts at $82,000 and has a nicer interior. But the Denali Ultimate is rarer, has a different grille, and tells a specific story about its owner. If you want to stand out in the country club parking lot, this is how you do it .

This visual shows the real cost of each trim beyond the window sticker. Notice the $30,000 gap between SLE and Denali Ultimate.

The Tech You Actually Get (And What’s Still Missing)
Standard across all trims:
- 10.2-inch touchscreen (not the 16.8-inch screen—that’s 2025+)
- Wireless Apple CarPlay and Android Auto
- 12.3-inch digital driver information center
- Google Built-In (Assistant, Maps, Play Store)
- OnStar Remote Access (3 years on SLE/SLT/AT4; OnStar Premium on Denali/Ultimate)
- Front Pedestrian Braking
- Lane Keep Assist with Lane Departure Warning
- IntelliBeam auto high beams
- Following Distance Indicator
Not standard (annoying):
- Adaptive cruise control — still optional on most trims, standard only on Denali Ultimate with Super Cruise package
- Surround Vision camera — optional on SLT/AT4, standard on Denali/Ultimate
- Super Cruise — locked to Denali Ultimate, requires Advanced Technology Package
Super Cruise, explained:
Super Cruise enables hands-free driving on over 200,000 miles of compatible highways in North America. It uses a driver-attention camera and LiDAR-mapped roads. It works incredibly well. It is not available on SLE, SLT, or AT4. It is optional on Denali Ultimate. It costs extra.
“This is the semi-autonomous driving system that actually works, but GMC keeps it firmly in the luxury zone.” — Kelley Blue Book .
Yukon vs. Yukon XL: The 15-Inch Decision
Standard Yukon:
- Length: 210 inches
- Wheelbase: 121 inches
- Cargo behind third row: 25.5 cu-ft
- Cargo behind first row: 122.9 cu-ft
- Third-row legroom: 34.9 inches
Yukon XL:
- Length: 225.2 inches
- Wheelbase: 134.1 inches
- Cargo behind third row: 41.5 cu-ft
- Cargo behind first row: 144.7 cu-ft
- Third-row legroom: 36.7 inches
The decision:
If you carry adults in the third row regularly, buy the XL. Those extra 1.8 inches of legroom are the difference between “I can survive” and “I’m never sitting back here again.”
If you need cargo space behind the third row, buy the XL. 41.5 cubic feet fits strollers, golf bags, and Costco runs without folding seats.
If you park in a garage or a city, buy the standard Yukon. 225 inches is Suburban territory. Measure your garage twice .
The 2024 Model Year “Update”: Read This Before You Overpay
Here’s the part the salesperson won’t tell you.
The 2024 GMC Yukon has no meaningful changes from the 2023 model.
The only difference:
- OnStar service packages were reshuffled. SLE/SLT/AT4 now get three years of Remote Access; Denali/Ultimate get three years of OnStar Premium.
- That’s it.
What you didn’t get in 2024:
- The 16.8-inch vertical screen (2025)
- Night Vision (2025)
- AT4 Ultimate trim (2025)
- Updated grilles and lighting (2025)
What this means for you:
If you find a 2023 Yukon with the same engine, trim, and options as a 2024, buy the 2023. It’s the exact same vehicle, and the depreciation has already hit the previous owner. The 2024 is a carryover year in the worst way—no improvements, same price, newer model badge.
“The GMC Yukon rolls into 2024 with few changes.” — That’s Kelley Blue Book’s official verdict. Read between the lines .

FAQ: 2024 GMC Yukon — What Buyers Actually Ask
What is the towing capacity of the 2024 GMC Yukon?
8,400 pounds maximum, achieved with the 5.3L V8 and rear-wheel drive. The 6.2L V8 tows approximately 8,300 pounds; the Duramax diesel tows approximately 8,200 pounds. Yukon XL figures are slightly lower (7,400–8,300) .
Is the 2024 Yukon reliable?
The 2024 model is too new for long-term data, but the powertrains are carryover. The 5.3L and 6.2L V8s have decades of collective history; the 3.0L Duramax has a strong reputation since its 2020 introduction. The 10-speed automatic has had mixed reviews; 2024 calibration is mature .
Does the 2024 Yukon have Apple CarPlay?
Yes, wireless. Standard on all trims. Google Built-In is also standard. GM has not removed CarPlay from the Yukon .
What is the fuel economy of the 2024 Yukon?
- 5.3L V8: 15/20/17 MPG (city/hwy/combined)
- 6.2L V8: 14/18/16 MPG (premium fuel)
- 3.0L Duramax: 23/27/23 MPG (RWD); 21/26/22 MPG (4WD)
Can I get the Duramax diesel in the AT4?
No. The diesel is not available on the AT4 trim. AT4 buyers get the 5.3L V8 standard or optional 6.2L V8 .
What is Super Cruise, and how do I get it?
Super Cruise is a hands-free highway driving system. It is only available on the Denali Ultimate trim with the optional Advanced Technology Package. It is not available on SLE, SLT, AT4, or standard Denali .
Is the Yukon XL worth the extra length?
Yes, if you need third-row cargo space or adult-friendly third-row legroom. The XL adds 1.8 inches of third-row legroom and 16 cubic feet of cargo space behind the third row. It also adds 15 inches of length, which may not fit in standard garages .
What’s the difference between the 2024 and 2025 Yukon?
Significant. The 2025 model (announced late 2024) features a redesigned interior with a 16.8-inch vertical screen, Night Vision, AT4 Ultimate trim, and updated exterior styling. The 2024 is a carryover year with minimal changes. If you want the latest tech, wait for 2025 .
How much should I pay for a 2024 Yukon?
Kelley Blue Book Fair Purchase Price averages:
- SLE: $58,088
- SLT: $62,339
- AT4: $70,927
- Denali: $73,725
- Denali Ultimate: $94,946
These are national averages; your local market may vary .
Is the Yukon better than the Chevrolet Tahoe?
Mechanically, they’re identical. The Yukon has slightly different styling, a more premium interior on Denali trims, and a higher price tag. The Tahoe is the value pick; the Yukon is the premium pick .
The Bottom Line: Who Should Buy a 2024 Yukon?
You are the target buyer if:
- You need three-row seating with actual space and prefer body-on-frame durability.
- You want a V8 because you believe gasoline engines should make noise.
- You drive enough highway miles to justify the Duramax diesel’s 27 MPG.
- You value resale value—the Yukon leads its segment .
- You find a lightly used 2023 and save $10,000 over a 2024 that’s identical.
You should look elsewhere if:
- You need maximum towing capacity. Ford and Jeep both out-pull the Yukon by 1,000+ pounds.
- You want the latest interior technology. The 2025 Yukon’s 16.8-inch screen and Night Vision are significant upgrades.
- You’re on a strict budget. The Chevrolet Tahoe is the same truck with a Chevy badge and a lower price.
- You want a diesel AT4. GMC refuses to build it.
The Honest Truth
The 2024 GMC Yukon is a transitional vehicle. It’s the last year of the pre-refresh interior, the final chance to buy a Yukon without the massive vertical screen, and the only model year that will quietly exist between two distinct generations.
Is it a good SUV? Yes.
The 5.3L V8 is bulletproof. The Duramax diesel is a unicorn. The Denali interior legitimately rivals Cadillac. The XL’s cargo space is class-leading. The resale value is excellent.
Is it the right time to buy? Not unless you’re getting a deal.
The 2025 model brings Night Vision, a 16.8-inch screen, the AT4 Ultimate trim, and Vader Chrome. That’s not a refresh; that’s a genuine generational leap. If you buy a 2024 in 2026, you’re buying a truck that was already two years old when it rolled off the line.
But here’s the counterargument: the 2024 Yukon is the last of its kind. It has analog gauges surrounding a digital cluster. It has a 10.2-inch screen that’s big enough without dominating the dashboard. It has column shifters and physical buttons and a vibe that says “I’m modern enough, but I don’t need a tablet glued to my dash.”
Some buyers want the future. Some buyers want the present, refined.
The 2024 Yukon is for the latter.
If you find one at the right price—$5,000+ below MSRP, or a clean used 2023—you’re buying a proven, comfortable, capable SUV that will haul your family, tow your boat, and never ask you to download an over-the-air update to turn on the heated seats.
That’s not nothing.
That might be everything.
