2020 Silverado With Duramax 3.0-Liter Diesel MPG Revealed (Better than Colorado Duramax)

General Motors reported this morning that the all-new Silverado equipped with the 3.0-Liter Duramax diesel engine has earned an EPA-estimated 33 MPG Highway in 2WD configurations. Here is a quick look at the numbers we have so far:

2WD Silverado Duramax = 33 MPG Highway, 23 City

4X4 Silverado Duramax = 29 MPG Highway, 21 City

 

Here are a couple of quick comparisons:

2019 Ford F-150 2WD Diesel = 30 Highway, 22 City

2019 Ford F-150 4WD Diesel = 28 Highway, 22 City

2019 Ram 1500 2WD Diesel = 27 Highway, 20 City

2019 Ram 1500 4WD Diesel = 27 Highway, 19 City

**2020 Chevrolet Colorado 2WD DIesel = 30 Highway, 20 City

**2020 Chevrolet Colorado 4WD DIesel = 28 Highway, 19 City

“We designed the all-new Silverado and the all-new 3.0L Duramax turbo-diesel to deliver both performance and efficiency,” said Tim Herrick, Silverado executive chief engineer. “The engine utilizes state-of-the-art technologies to optimize every drop of fuel, and takes advantage of architectural changes to make Silverado larger, lighter and more aerodynamic than before. The resulting combination offers all of the performance, refinement and capability customers want in a full-size truck, with highway fuel efficiency you would expect from a family sedan.”

 

The trade-off for fuel economy alone will worth calculating. In addition to the higher fuel cost compared to gasoline, for the LTZ and High Country, the 3.0L Diesel is a $2,495 option (identical to that of the 6.2L V-8). For the LT and RST, it is a $3,890 increase over a 2.7L Turbo engine. For those looking for diesel towing capability, the choice will be an easy one. 

 

The EPA has not yet published full MPG and emissions information on the new Duramax at its site, www.fueleconomy.gov. Once data is posted we will do a more in-depth post on the comparison to some other Silverado models. First deliveries of the 2020 Silverado with the Duramax engine will be this coming fall.

The increase in MPG comes at the cost of towing capacity in comparison tho, but 9,000+ towing is plenty for a 1500.

Hottttt.

 

Kinda embarrassing to Colorado/Canyon, but owns the Ford 3.0 Powerstroke, especially in 4x4 configuration. 

 

I bet the Chevy real world #s will beat 29 highway.

Why is there a 4mpg difference between the 2wd and 4wd in the highway? The 4wd will have a little extra weight with a transfer case and front diff, but I can’t imagine that causing a big difference in fuel mileage.

4wd will be a little higher in height as well, that kills MPG.

Per the specs on the Sierra SLT the height of the 4wd is 75.40” and the 2wd is 75.35. The 4wd trucks are no longer taller than 2wd trucks like they were years ago. That’s why I and wondering what is causing the big difference between the mileage between the two.

The difference is the way the EPA test the 2 and 4 wheel drive trucks. The extra weight of the 4 wheel drive puts those trucks in a different class, so they are tested under higher loads than he 2 wheel drive models, per a TFL video.

God help you if that engine needs work 😳

Looks really complicated!

 

I wonder what towing mpg is?  Gotta be fairly decent.  If money wasnt an Issue id totally get it over the 6.2.  It is a really really attractive option.

 

The problem with these upgrades is you may as well just get the 2500HD 6.6 duramax for the real deal, and probably for less cost,  if the concern is wanting max towing power.

 

Reminds me of the 1500HD.  Just a strange segment that doesnt fill the gap well...but looking back with hindsight I totally.wish I bought the 1500HD with a 6.0!

From what I’ve read this is supposed to be the same cost as the 6.2 option. I was about to pull the trigger on a 6.2 but this new option really has me reconsidering now.

Now that makes sense to why there would be such a large gap.

143 HP less than the 6.2... that one hurts my pride a bit. Same torque numbers though. Basically, the MPG increase is the only attractive selling point for this motor.. I can't wait to drive one to see how it feels.. maybe my next truck.

      Hi everyone,
       
      So since my purchase of a 2016 Silverado 1500 in May the main problem I've had with the truck is its inconsistent ride quality. The truck is a WT with power windows and locks. Cloth seats. And vinyl floor.
       
      The truck only has 27000 miles, well kept and maintained. Used as a commuter truck to work, aswell as work on the side (Electrician). Truck was purchased with only 22000 miles on it. No issues other than leaking pinion seal which is in the process of being fixed. 
       
      At first I thought it was the tires so I had them balanced, rotated, and had an alignment done. While that helped it didnt fix the issue at hand which is how hard this truck drives
       
      It's a very uncomfortable ride at all speeds. Even on freshly paved highways and roads it still drives rough. What defines "rough" is the hitting of minor bumps. It can be just an ever so slight crack in the road to minor pits. I've done some testing and drove another vehicle (An f-150) down those same roads and had no where near as much of a impact and hit as my own truck. Now it's not a major impact like hitting something that you really shouldnt. But it's very unsettling and jarring at times as you would be driving the same roads you have been for years in different vehicles, and when you least expect it feel a nice jolt in your back when you usually wouldnt. 
       
      If you need more understanding, put a handful of change in the compartment under the AC controls and drive around.
       
      I was wondering if it has anything to do with the stock suspension that comes along with the truck. Should I try out new shocks? Is there anything else I should try? I have no clue what to do and where to start but driving 45 minutes to work with the truck makes my back hurt as much as after an 8 hour day of work. 
       
      Thanks

      GM recalls 160,000 pickup trucks in Canada for fire risks, nothing announced in US yet
      As of right now there is a recall for all GM 1500's years 2014-2018 that have both a rear window defogger and a power sliding rear window. 
      https://www.cnet.com/roadshow/news/gm-recall-pickup-trucks-canada-fire-risks/
       
       
      That recall has not been expanded to the US.
       
      I Just got off the phone with GM and filed a request to have the recall expanded to the US. I would encourage everyone who this applies to in this forum to do the same. It takes about 5-10 min but could save us all a lot of hassle later. 
       
      HAVE YOUR VIN READY
      Call GM @1 (866) 522-9559
      Reference this recall number:
      Manufacturer Recall Number
      N192220470
      (This is the recall number from GM in Canada)
      (reference: 
      https://wwwapps.tc.gc.ca/Saf-Sec-Sur/7/VRDB-BDRV/search-recherche/detail.aspx?lang=eng&mk=0&md=0&fy=0&ty=9999&ft=&ls=0&sy=0&rn=2019325&cf=SearchResult&pg=50)
       
       
      They will tell you that the recall only applies in Canada and not to your VIN. 
      Express to them that the recall needs to be expanded to the US since our vehicles are also affected. 
       
      Please post here if you have called GM (just so we can keep track) 
      Please also post if you have experienced this issue (smoke, glass breakage, etc) 

       
      Affected components: electrical – rear window defroster on trucks equipped with the power sliding rear window.
      Affected vehicles:
      2014-2018 Chevrolet Silverado 1500 2015-2019 Chevrolet Silverado HD 2014-2018 Chevrolet Silverado LD 2014-2018 GMC Sierra 1500 2015-2019 GMC Sierra HD 2014-2018 GMC Sierra LD  
       
      It may be a good idea to sticky this topic.
