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.
