2021 GMC Yukon Diesel Going On Sale In November: Report

In January of this year, the 2021 GMC Yukon debuted with three engine options. However, only gasoline factories were initially available. The all-new Duramax 3.0-liter inline-six turbodiesel was announced late.

For those waiting for an update on the diesel-powered Yukon and Yukon XL, GM Authority reports that it will be available for order in November. The oil burner will join other power plants in the list of options, expanding the options for buyers who want fuel efficiency in their SUVs.

The new 3.0-liter Duramax engine is the same as that of the Tahoe and Suburban, meaning it will produce 277 horsepower (207 kilowatts) and 460 pound-feet (624 Newton-meters) of torque. By comparison, the largest engine option of the group, the 6.2-liter V8, produces 420 hp (313 kW) and the same pulling power. All three engines are mated to the company’s Hydra-Matic 10-speed automatic transmission.

The downside, however, was the fuel consumption of the gasoline plants. In its version of the Chevrolet Tahoe and Suburban, the gasoline engines made it good fuel efficiency in the city but a little bad on the highway. These numbers reflect the Yukon and Yukon XL, but do not include the diesel-powered plant ratings.

With the 2021 GMC Yukon diesel on its way to order books, we’re expecting official MPG numbers sooner rather than later, and we expect better than what the gasoline variants have returned.

A little disappointing, however, the diesel engine option will not be available for the all-terrain Yukon AT4. Why? Well, AT4’s exclusive fascia gets in the way of the diesel engine intercooler and intercooler piping.
