The all-new 2021 GMC Yukon officially dropped cover in January during a special media event in Vail, Colorado. Among the long list of highlights was confirmation that the next-gen SUV would offer a new turbodiesel engine. However, as GM Authority exclusively reported back in May, diesel-powered 2021 GMC Yukon diesel models have late availability. Now, we’re here to report on another exclusive with news that the new Yukon diesel will be available to order in November.
For those who may be unaware, the 2021 GMC Yukon diesel is equipped with the 3.0L I6 LM2 turbodiesel Duramax. Output from the oil-burner is rated at 277 horsepower at 3,750 rpm, and 460 pound-feet of torque at 1,500 rpm. The engine features dual-overhead cams and direct injection.
As we’ve covered previously, the diesel engine option is not offered on the off-road-oriented 2021 GMC Yukon AT4, given the AT4’s unique front fascia obstructs the diesel’s intercooler and intercooler piping. The off-roader 2021 Chevrolet Tahoe Z71 also does not offer the diesel engine option for the same reason.
The new powerplant in the 2021 GMC Yukon diesel is the third engine option in the lineup, with the other two options including the naturally aspirated 5.3L V8 L84, which doles out 355 horsepower and 383 pound-feet of torque, and the naturally aspirated 6.2L V8 L87, which produces 420 horsepower and 460 pound-feet of torque.
All three engines utilize GM’s Hydra-Matic 10L80 10-speed automatic with regard to transmission duties.
The GMC Yukon nameplate was completely overhauled (redesigned and re-engineered) for the 2021 model year. That includes a new exterior and interior, plus the latest technology features. The 2021 GMC Yukon rides on the GM T1 platform, and now features a new multilink rear suspension.
The new Yukon also offers available four-corner Air Ride Adaptive Suspension with four inches of ride height adjustment and an automatic self-leveling feature. Inside the cabin space, passengers will enjoy an extra 10.1 inches of third-row legroom and an extra 28.2 cubic-feet of max cargo room for the standard Yukon model.
Production will take place at the GM Arlington plant in Arlington, Texas.

Why is it that I never get a reply ?
There is plenty of room under the hood for the 6.6 Duramax. In my opinion the baby Duramax doesn’t belong in a full size suv. People don’t by a full size suv for fuel economy. People that buy a full size suv often pull boats or campers. I will stick with my 7.3 liter Excursion with an F350 suspension. Maybe Duramax Specialties or Duraburb can help me out in the future.
Jonathan, As is many times the case, high in the GM glass tower, away from the man-on-the-street who buys the product, there are those who think they know better… timing is everything and GM has far too long put the 3.0 diesel on the back burner and it seems doesn’t give it the credit it deserves… Lutz/Clutz stated he thought sales would be 10% or so… if they’d get their heads out of the sand and listen to the people who buy the product, they’d have 15 to 20% of sales in the diesel segment… how ’bout putting a great diesel in the Acadia? Wow!
That’s how most glass towers rotate though isn’t it. Anyone remember the 4.5? They supposedly built a new plant and produced hundreds of engines which remain on the racks… good call glass tower. Kerby
Any News when we will be able to order the Yukon Diesel?
