A rumor from August suggests that the 2021 Yukon with the diesel engine goes on sale in November. At least for this model year, the powerplant is not available on the off-road-oriented AT4 model because the front fascia interferes with the turbo's intercooler and its piping.
For comparison, the 6.2-liter V8 offers 420 hp (313 kW) and 460 lb-ft (623 Nm). It gets 15 miles per gallon city, 20 mpg highway, and 17 mpg combined for the rear-drive layout. With four-wheel drive, the fuel economy is 14 mpg city, 19 mpg highway, and 16 mpg combined.
The 2021 Denali has a slightly different cabin than other versions of the Yukon. It features high-end touches like a power-sliding center console, 15-inch head-up display, and nine available camera modes, including a 360-degree perspective. The interior also has luxurious things like hand-finished real wood trim and hand-sewn stitching.
To take the Denali further upmarket, there are Deluxe, Premium, and Ultimate packages. They bundle together various options and amenities at a discount in comparison to ordering the luxuries separately.
