Earlier this year, the 2021 GMC Yukon debuted with a refreshed exterior, revised engine options, and improved interior space. With customer deliveries set to begin this summer, the online configurator for GMC's premium full-size SUV is now live, allowing customers to build their perfect 2021 GMC Yukon.

Currently, only two trims are available on the 2021 GMC Yukon and the larger 2021 GMC Yukon XL's configurators: SLT and the luxurious Denali. The SLE trim and the new off-road-focused AT4 trim will be available at a later date. Like the new Chevrolet Suburban and Chevrolet Tahoe, available powertrains for the 2021 GMC Yukon include a 355-hp 5.3-liter V8, and a 420 horsepower 6.2-liter V8. A 3.0-liter inline-six turbo-diesel engine delivering 277 hp and 460 lb-ft of torque will also be available at a later date.

Pricing for the base SLT trim starts at $61,795 with 2WD and $64,795 with 4WD. Upgrading to the range-topping Denali trim increases the price to $69,695 for the 2WD version and $72,695 with 4WD. The 2WD XL SLT version, on the other hand, starts at $61,795, while the 4WD version starts at $64,795.

Topping the range, the 2WD and 4WD 2021 GMC Yukon XL Denali starts at $72,395 and $75,395 respectively. All prices exclude the destination charge. All 2021 GMC Yukons only have one available standard color: Summit White. For an extra cost, the full-size SUV can be finished in one of several available premium colors. Many are available for an extra $495, but the most expensive White Frost Tricoat adds an extra $1,095 to the cost.

Available packages for the 2021 GMC Yukon Denali include the Denali Premium Package, which adds a plethora of luxuries including power-retractable assist steps with illuminated perimeter lighting, a panoramic sunroof, rear camera mirror washer, rear camera mirror, and more. GMC is currently offering the Denali Premium Package for a discounted price of $6,500, reduced from $7,000.

By contrast, the most expensive package available for the SLT trim is the SLT Luxury Plus, which adds new luxuries including a panoramic power sunroof, a heated steering wheel, and second and third-row power-release 60/40 split-folding bench seats. As standard, the 2021 GMC Yukon rides on 20-inch wheels, but these can be upgraded to a set of 22-inch wheels available in different designs at an extra cost. Fully loaded, our 2021 GMC Yukon came to $85,360, while the fully-specced XL version will cost a whopping $88,110.

But if you want to build the most expensive 2021 Yukon, it's going to have to be in Denali XL guise. Check all the boxes, and you'll quickly find the sticker price to be over $90,000. GMC is certainly testing new waters with a price like that, but there's likely untapped potential in that Denali name still.
