2020 Chevrolet Silverado 3.0L Duramax Fuel Economy Released

The Environmental Protection Agency has released fuel economy figures for the 2020 Chevrolet Silverado with the turbocharged 3.0-liter diesel Duramax LM2 inline-six engine.

According to EPA estimates, the two-wheel drive version of the truck will deliver 33 mpg highway and 23 mpg city, while the four-wheel drive version is rated at 29 mpg highway and 23 mpg city.

By comparison, the two-wheel drive 2019 Ford F-150 PowerStroke is rated at 22 mpg city and 30 mpg highway, while four-wheel drive trucks return 21 mpg city and 28 mpg highway.

The Chevrolet Silverado’s all-new 3.0L Duramax inline-six turbo-diesel engine offers segment-leading torque and horsepower, in addition to a focus on fuel economy and capability.

The EPA has yet to release fuel economy figures for the 2020 Ram 1500 EcoDiesel, although Fiat Chrysler said previously that it is expecting the truck to have class-leading fuel economy figures.

General Motors‘ press release made no claims that the Silverado‘s fuel economy figures were “class leading” and it didn’t reference the fierce segment competition, so it does seem as though FCA is destined to wear the mpg crown this time around.

“We set out to offer light duty truck customers the best of diesel – outstanding fuel economy, great horsepower and responsive torque – plus unexpected levels of refinement,” said GM’s diesel truck program director, Nicola Menarini. “We leveraged our global diesel expertise to make sure the all-new 3.0L Duramax turbo-diesel engine offers the impressive performance and durability our truck customers demand.”

The 2020 Chevrolet Silverado with the 3.0-liter Duramax engine is rated at 277 horsepower and 460 foot-pounds of torque, while the F-150 PowerStroke is rated at 250 horsepower and 440 foot-pounds. Ram’s EcoDiesel makes the second most amount of power at 260 horsepower and the most torque at 480 foot-pounds.

GM says the 2020 Chevrolet Silverado will tow 9,300 pounds and has a max payload of 1,870 pounds when equipped with the Duramax engine, which meets “the towing needs of about 90 percent of light-duty customers.”

When the truck goes on sale later this year, Chevy will charge owners the same for the diesel engine as it does for the 6.2-liter L87 V8 engine, which carries a $2,495 premium over the 5.3-liter V8.

  1. It will be interesting to see if Ford’s EPA scandal bleeds over to their diesel milage!

  4. Fingers crossed that the 2021 MY Chevrolet Suburban and Tahoe get this exciting new powertrain, as it’ll give them the perfect blend of capability and efficiency for true family duty.

    1. YES YES YES!!!!!

      I will be the first person to put a deposit down if so!

      Sadly, I have a feeling that GM will only offer the 2.7 as the “fuel efficient offering”.

      1. @Henry We’ll have to wait and see about that. Both the 3.0 liter diesel and 2.7 liter turbo 4 cylinder are likely to be added to the new Suburban and Tahoe’s engine lineup since both SUVs will share the new T1 architecture with the recently overhauled Silverado 1500.

  5. Hmmm… might have to test drive and see if I like it better than my 6.2. But only 4 comments in and I’m not sure if I’m allowed to be excited about this. Maybe I should check other sites?
    I don’t really see the point though. Once FCA releases 34 mpg(2 wheel drive) and 30mpg (4×4), I know you guys will tell me to be disappointed even though I’m already supposed to be disappointed in the rest of the truck. Still can’t wait for the next gen truck though. Then I’ll be allowed to like my truck!

  6. I think its good that they are trying but there best is just getting us to third place they need to rethink there strategy because where I live I have went from seeing chevy truck’s everywhere to now seeing rams everytime I look around

  8. Amazing numbers. Nice to see GM making others play catch-up once in a while. Looking forward to trading my Colorado diesel for one of these beauties

  9. This is good news for GM. If FCA beats this inwont be surprised if they are sneaking money over for bragging rights. Make an option with high gears and low roll resistance tires to accomadate the figures.I think the inline 6 is a better motor and GM could easily add more power without offsetting the fuel efficiency to match the Ram. But like I say it’s not always what the paper says, real world performance speaks volumes over paper. Some just want to brag “Best in Class” for advertising purposes but we will see how well they all are when they are out together in a show off.

  10. The 2020 Chevrolet Silverado equipped with turbocharged 3.0-liter diesel Duramax LM2 inline-six engine gets 33 miles per gallon on the freeway; this is more than enough range for the new Silverado Diesel to travel from San Francisco to Los Angeles and still have plenty in the tank.

  11. I criticize GM a lot, but the engineers of this engine deserve a huge applause.

  12. Now if the media just doesn’t become obsessed with interior we may have a shot. The powertrain should always be the focal point of any truck build. Saying your truck is better because it has a better so called interior is a joke!!!

    Trucks are supposed to be trucks!!!

  13. Well i owned a 2014 ram ecodiesel crew cab 4×4 and it was a good truck. I hated the $280 oil changes and $90 fuel filter every 8k miles. I averaged 24.5 mpg with a mix of driving and towing very little.
    Now I have a 2018 Chevy crew cab 4×4 with the 6.2 and i have 28k plus miles on it on the “TRIP 1” and I have towed with it alot more than i did with the ram. Trip 1 mpg is averaging 22.6 mpg. I recently went to Reno and back to Bend, Or and averaged 26.7 mpg at about 70 mph average. It is very responsive and fun to drive, passing is not an issue should you need to. Big plus is the oil change is only$49 about every 6,500 miles. I will stick with the 6.2 and not need to fuss with fuel jelling issues in the winter. Plus the dealer gave ne an unlimited power train warranty for as long as I own the truck good at any asme certified shop with only a $100 deductible..

  14. Why doesn’t GM come out with some kind of body that doesn’t rust!
    Why do they wait till someone else does it then they tweek it slitly so they get the one up.
    Where is the GM working truck?
    They don’t even offer a truck with a heavy duty tire or brake’s ( 19.5).
    It’s like looking for a 4 leaf clover to see a GM working truck with a heavy duty service body or crain on it, and you wonder why GM is 3 Rd in the truck world.
    The 6.7 PS is everywhere , they’re selling more PS than GM can sell 1500s.
    Ram truck is out pulling and out performing GM by huge margins.
    And you wonder

  16. It amazes me that we can have an announcement this significant and people act like its so insignificant. Read this real slowly…A heavy, large, refined, capable full size truck that is going to beat all others that are currently on the market by at least 3 mpg on the highway, and all gas variants by at least 7 will soon be for sale in America. Just one year ago the 2.7L Ecoboost was the gas powered champ of the segment at 22 combined (this one is 5 above that). The 2.7L fell to the reworked Ecodiesel by only one, and even compared to mid size trucks, only barely fell to the baby Duramax and tied the best gasser. No matter what Ram does tomorrow, we should all be in awe of a full size 33 mpg truck that has zero electrification. Am I the only one that appreciates the engineering it took to get this rating. I just traded a tiny Fiat 500 with a 6 speed that had an estimate of 33 highway. It was about half the mass and one- third the power and one- fourth the torque of this amazing truck.
