2021 GMC Yukon XL Now In Production

General Motors’ full-size SUV lineup is filled end to end with next-gen models, including the re-engineered and redesigned 2021 GMC Yukon XL. Now, GM Authority has learned that production for the latest fifth-gen Yukon XL is underway at GM’s Arlington Plant in Arlington, Texas.

Production for the 2021 GMC Yukon XL officially kicked off on July 13th, which means the all-new standard-length Yukon and the all-new extended-length Yukon XL are both currently rolling off the line. The two Yukon models join the equally all-new 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban at the Arlington Texas facility.

Production for the new 2021 Tahoe and standard-length 2021 Yukon began June 26th, while production for the all-new Suburban started alongside the Yukon XL on July 13th.

As before, the 2021 GMC Yukon XL is offered as the extended-length body style of the flagship SUV nameplate, with the latest model year bringing a higher level of craftsmanship, premium accommodations, innovative features, and advanced technologies. The 2021 Yukon XL is 225.7 inches long, while the 2021 Yukon is 210.7 inches long.

The 2021 GMC Yukon rides atop the all-new T1 vehicle platform, which is designed specifically for pickup trucks and body-on-frame SUVs, and also underpins the 2019 Chevrolet Silverado and 2021 Cadillac Escalade.

The 2021 GMC Yukon XL will offer three engine options, including the naturally aspirated 5.3L V8 L84 with 355 horsepower and 383 pound-feet of torque, and the naturally aspirated 6.2L V8 L87 with 420 horsepower and 460 pound-feet of torque. The latest 2021 model year also includes the addition of the turbodiesel 3.0L I6 LM2 Duramax, which doles out 277 horsepower and 460 pound-feet of torque. The new diesel engine will see late availability.

The new 2021 GMC Yukon XL is equipped with an independent rear suspension, which departs from the previous generation’s solid rear axle and provides greater handling and ride benefits. Four-corner Air Ride Adaptive suspension with up to four inches of ride-height adjustments is offered.

The trim level lineup includes the base-model SLE, the midrange SLT, the off-roader AT4, and the range-topping Denali.

Stay tuned, as we’ll have more on the 2021 GMC Yukon XL posted soon. In the meantime, make sure to subscribe to GM Authority for more GMC Yukon news, GMC news, and around-the-clock GM news coverage.

  • It is great news to hear that production has finally begun on the 2021 GMC Yukon XL. However, I'd like to know when the "Phase 2" of production will begin.
    I ordered my Denali in late June. Unfortunately, the dealer was "not" able to place the order with GM, due to the "Premium Capability Package With Active Response 4WD (F47-Adaptive Air Ride Suspension & G96-Electronic Limited-Slip Differential)" was NOT available yet. I spoke to the dealer today, and GM will still not accept my order yet.
    Does anyone know when that phase of production will start?

    • Well, I just got the answer to my question.
      Orders with special features like “Premium Capability Package With Active Response 4WD” (F47 Adaptive Air Ride Suspension & G96 Electronic Limited-Slip Differential)” won’t be starting production, until the weeks of Sept 7th thru Oct 11th (Phase 2 of production). So it's looking more like a Christmas delivery...as of today's information.

  • Until GMC upgrades interior and has other choices besides wheat or black i will shop other brands. When your paying 70,000.00
    Plus you expect better options on interior colors on leather colors. WAKE UP GMC, GET COMPETIVE ON INTERIORS. Rest of Suv Yukon is acceptable.
    Look at Rams interior options on Ram 1500.
    Awesome.

  • Hope our vehicle is in production. Ordered it on May 18th 2020. It was GMCYukon Denial. Hope it get it soo. Always drove GMC Yukon Denial for a very long time.

  • On the Canada Build and Price site, the Premium Capability Package withActive Response 4WD now comes up. I would have presumed that since it shows up, one could order the Yukon Denali (not XL) for a fall delivery or at least get the order in the question for delivery. Seems to me strange that this would push delivery to Christmas with this optional Package.

    Any comment?

    • I was being guardedly optimistic saying Christmas. My dealer said "maybe" by late November. It all comes down to the plant being able to produce on schedule (Phase 2 is now Sept 7th thru Oct 11th for XL's with the package - it was previously July 21st). Unfortunately, I've been told they're only running at 25%, due to Covid-19. Therefore, any date given by the dealer is just a guesstimate based on today's information. He said things are changing by the hour.
      The Premium Capability Package with Active Response 4WD does come up as a choice to build, on gmc.com. However, the actual dealer order is still not able to be submitted with it to GM, for my SUV yet.

  • What I'm saying is for 70-80,000. I expect far better interiors in your Yukon/Serbia that you have been offering the last few years. Wheat &black leather interiors ain't getting it for the money. Check out Rams 1500 interiors outstanding. I've 6 Gmc since 2004 and all the same options on interior.
    I'll not buy another till you make changes.
    Chevy, Cadillac, Mercedes GLS Audi Q8 are my choices.
    There is nothing wrong with SUV/P/U TRKS. EXCLUDING INTERIORS.
    MAKE A CHANGE GMC IF YOU WANT MY BUSINESS. I CURRENTLY OWN 2015 SLT PREMIUM/2017 YUKON DENALI.
    Tired of wheat/black choices.
    Get in the game.

  • When could one reasonably expect delivery of a Denaili in Canada with he Premium Capability Package with Active Response 4WD, in Canada and any idea when the system would accept an order with it?

  • Does anyone have any insight as to when the AT4 Yukon and Yukon XL will be in production? Im so ready to try this out and place an order

  • If they did not fix their paint problems i would not buy another GMC
    i have a 2017 Yukon Xl Denali that i bought at the end of 2017and the paint failed early 2021 i am just outside the 36 month warranty so was going to cost me 3k to repaint the hood and roof where the clear failed and the dealer said GM would help and pay half so it still cost me over $1500
    this is happening mostly to the onyx black so if you buy a Denali you most likely will get it in Black and be repainting it in a few years
    not something you should have to do on a 3 year old vehicle that cost over 75k
