Following last month’s unveiling of the new Chevrolet Tahoe and Suburban, GMC has just taken the wraps off their compliments, the 2021 Yukon and Yukon XL. The standard length Yukon adds five inches of wheelbase and six inches of overall length. The Yukon XL grows four inches in wheelbase but less than one inch overall. Both are completely redesigned full-size body-on-frame SUVs. The new generation Yukons are loaded with added space, capabilities, and technology. New as well for the Yukon will be a more rugged AT4 trim. Highlights of the Yukon include a first-in-class available four-corner air suspension, a nine camera view monitor, rear camera mirror, and GMC’s ProGrade trailering system. The Yukon also features the most powerful engine in its class, an all-new 6.2-liter V8 rated at 420-horsepower with a standard 10-speed transmission. The also new Active Response 4WD system includes an electronic limited slip rear differential to improve both traction and overall handling control. The 2021 GMC Yukon will go on sale this summer.
