About GMC Yukon XL


The 2020 GMC Yukon is a full-size SUV that is mechanically identical to the Chevy Tahoe, just as the Yukon XL is mechanically identical to the Chevy Suburban. Choosing between these corporate rivals may be based on design preferences or proximity to a dealership, but GMC variations tend to be a little more upmarket. This is mirrored in the pricing. Ascend to the Denali trim level, and the Yukon can compete with the true luxury Cadillac Escalade.

For the time being, the Yukon is a classic truck-based, body-on-frame SUV with great towing capability, some serious off-road moves, and the capacity to carry significant weight inside its cabin. The Yukon XL comfortably seats eight adults and their belongings.

The Manufacturer’s Suggested Retail Price (MSRP) for the 2-(rear)-wheel-drive 2020 GMC Yukon SLE is $49,600. Add the $1,295 destination fee for a total of $50,895 without options. Most buyers should budget several thousand dollars more.

Thee 2020 Yukon SLT, for example, starts at $56,095. Four-wheel drive costs an extra $3,000, while the XL model costs an extra $2,700. The price of a fully outfitted Yukon Denali XL with 4-wheel drive is $73,695. With a few possibilities, it’s possible to spend $80,000 or more. That’s approaching Cadillac Escalade territory.

The Yukon lineup is slightly more expensive than the Tahoe lineup. It is also more expensive than the Toyota Sequoia and Nissan Armada. Check out the Fair Purchase Price to see what other people in your region are paying for a new Yukon. The resale prices are predicted to be among the highest in their category.

Despite its traditional design, the 2020 Yukon’s riding quality is unmistakably modern. This is a large, robust SUV with good road manners but the feeling that it might pound a difficult road into submission. The optional adaptive suspension improves ride comfort by constantly monitoring and adapting to smooth out bumps.

The Yukon, on the other hand, can pull over 8,000 pounds and go off-road. Its basic 5.3-liter V8 engine is incredibly powerful. We’ve used it to tow trailers and RVs, climb hills, and swoop down highways. It’s mated to a perfectly acceptable 6-speed automatic transmission.

The considerably more powerful 6.2-liter V8 is standard in the Yukon Denali and can be purchased with the Graphite Performance Edition package in the SLT trim. This engine is linked to a 10-speed automatic transmission.

The optional 4-wheel-drive system is likewise reassuringly traditional, with a 2-speed transfer case providing adequate low-range gearing.
