The big Yukon carries over unchanged for the 2020 model year. It continues to rely on strong 355- and 420-horsepower V8 engines with a towing capacity of up to 8,500 pounds. The interior offers comfortable seating for up to eight and remarkable levels of luxury in Denali trim. Since General Motors is completely redesigning all of its full-size SUVs for 2021, including the Yukon, customers wishing for the latest in styling and technology need to wait a bit longer.
