Last week, we were the first to bring you news that the 2021 Chevrolet Tahoe diesel and 2021 Chevrolet Suburban diesel would see late availability. Now, GM Authority is bringing you yet another exclusive, this time with a report that the LM2 Duramax engine in the 2021 GMC Yukon diesel will also have late availability.
According to our sources, production of the 2021 GMC Yukon diesel will launch 12 weeks after the first examples of the next-generation Yukon roll off the line. This matches the late availability of the 2021 Chevrolet Tahoe diesel and 2021 Chevrolet Suburban diesel, as we reported last week.
Despite widespread disruptions caused by the COVID-19 pandemic, GM CEO Mary Barra recently stated that GM’s line of next-gen full-size SUVs were on track for first deliveries in June. Unfortunately for those buyers interested in acquiring a 2021 GMC Yukon diesel with the LM2 Duramax engine, it looks as though that particular configuration is still at least several months away.
As a reminder, the diesel engine in question is the 3.0L I6 LM2 Duramax, which joins the lineup for the 2021 model year. The diesel engine option is offered on every trim level except the new off-road oriented AT4. Output is rated at 277 horsepower and 460 pound-feet of torque. The 2021 GMC Yukon diesel equips the GM 10-speed automatic transmission for cog-swap duties.
In addition the LM2 Duramax engine, the next-gen Yukon is also offered with the naturally aspirated 5.3L V8 L84, which is offered as standard on all trims except for the range-topping Denali. Meanwhile, the 2021 GMC Yukon Denali gets the naturally aspirated 6.2L V8 L87 as standard. Both gas engines also connect to the new GM 10-speed automatic transmission.
