Back in May, we broke the news that the all-new 2021 Chevy Tahoe diesel and equally all-new 2021 Chevy Suburban diesel would have late availability. Now, GM Authority has exclusively learned that both oil-burner next-gen SUVs will be available to order in November.
In both models, the engine in question is the 3.0L I6 LM2 turbodiesel Duramax, which features dual-overhead cams and direct injection. The LM2 diesel engine is offered as an available option for every trim level with the exception of the off-road Z71. When equipped in the 2021 Chevy Tahoe diesel and 2021 Chevy Suburban diesel, the LM2 engine produces 277 horsepower at 3,750 rpm, and 460 pound-feet of torque at 1,500 rpm.
The rest of the engine lineup includes the naturally aspirated 5.3L V8 L84, which produces 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 connect to the GM Hydra-Matic 10L80 10-speed automatic transmission.
The 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban debuted side-by-side late last year in a special event in downtown Detroit. The 2021 Chevy Tahoe diesel and 2021 Chevy Suburban diesel join the lineup for the first time with this next-gen overhaul, which also includes a new underlying architecture, namely GM’s T1 platform, as well as a new independent multilink rear suspension. Further updates include revised exterior and interior designs, and the latest technology features.
Both models are assembled by GM USA at the GM Arlington plant in Arlington, Texas. Production for the 2021 Chevrolet Tahoe kicked off June 26th, 2020, while production of the 2021 Chevrolet Suburban kicked off July 13th.

I think the public would love to know the performance comparison of all three engines, the mileage rating of the new diesel, and the towing capacity comparisons of all three engines. What reared axle ratios will be available. and now that someone has awakened at GM how about offering different axle ratios from 3.08 or 3.23 to 4.10 and/or 4.56 gear ratios for those of us that would like to be able to customize our vehicles to our needs. Make the 3.23 or whatever gear ratio GM thinks most folks will live with and not know the difference and attain the corporate mileage requirements the gov't mandates. Let the rest of the more knowledgeable car buyers select the gear ratio that fits their needs. Make that policy part of the truck selection process when buying a new truck.The competition certainly does. I am a loyal GM guy for 60 years having bought hundreds of GM vehicles for personnel use and business use, but am about to buy a Ford F350 Diesel Dually because I can pick reared axle ratio and I believe the Ford truck is a better all around truck. Someone from GM hasn't been listening to the knowledgeable buyers for the last twenty years regarding the Suburban and the pickup market. Ford should not be the dominate truck sold in America.
I thought I saw here on GM that the tow rating for the diesel was 8000 Lbs for the 4x4.
I was super excited until I found out that the diesel isn't offered in the Z71 package.....
This comment is right on. As a Chevrolet Suburban owner my experience with my 2003 2500 LT 6.0l shows it is all about towing capacity . Flexibility is the name of the game.
You're going the wrong way! You're going in the wrong direction!!!
GM always seems last to the party when bringing any sort of diesel to market.
I thought GM was wrong only offering one axle ratio geared so high, until I drove and towed up to a 19,000 lb 5th wheel trailer with the new 10 speed transmission. The 2020 Duramax with the 10 speed is very smooth and has more power to the wheels than my 2018 2500 and 3500 Dually that I drove. I couldn’t believe the performance difference when the engine is rated the same Yes I traded 2500 and 3500 on identical 2020 trucks and couldn’t be happier.
Any idea when the diesel EPA numbers will be released?
I just hope they don't do the same that they did with the chevy cruze diesel. I have one at the dealer for over 4 months waiting for the cylinder head that is in back order from Germany. They bring them for a couple of years and then dump them and leave the customer with out the support
I'm a diesel fan so I'll check them out!
I'm glad that you are starting to sell diesel here in the USA vs sending over seas like you've been doing. I'll be getting one of the suburban's. We have vw passat that's diesel. Because no one has any diesel. Oh I'll also be up the chevy equinox, I love that smaller suv. Keep making diesel.
The diesel half ton truck is getting around 30 mpg on the highway. If they can do that for the Tahoe will be great. I just bought a 2021 with the 5.3 and the only thing I am not crazy about is the mpg.
I just bought my third Tahoe in the past four years and it seems that every time I want some thing in a model that model doesn’t come with it and you only could pick from two other models I wish Chevy would listen to the people that when they want to buy something they can select from all different models
