Silverado diesel 33mpg,,,

This impressive new inline six diesel engine makes a good truck even better. But this is the last chapter in IC only engines for passenger cars and light trucks. Electrification is the future of the industry. As mentioned in another thread, GM, Ford, and Tesla are all designing BEV pickup trucks that will be more capable and more efficient than the best gasoline and diesel powered pickups.

Those are definitely some impressive numbers.  Autoblog brought up some interesting points - they optimized the diesel for fuel economy and not towing, where it's down significantly on both Ford and Ram.

It's also really interesting that the numbers are better than Colorado/Canyon with their diesel.

https://www.autoblog.com/2019/07/25/2020-chevy-silverado-diesel-fuel-economy/


Chevy told us on the truck’s first drive that it optimized the truck for superior fuel economy, not superior towing. That’s obvious, as the Silverado is down significantly on towing capacity versus both the Ford and Ram. The 2020 Silverado diesel can haul a maximum of 9,300 pounds, whereas the Ford tops out at a much higher 11,400 pounds. Both of those are still well under Ram’s new max capacity of 12,560 pounds. Strangely enough, the Silverado makes more horsepower than both the Ford and Ram at 277 horsepower. It ends up between the two in torque, rated at 460 pound-feet of twist.

Funnily enough, these ratings make the full-size Silverado more efficient than the smaller Colorado and GMC Canyon diesel offerings. The highest fuel economy achieved by those trucks is 20/30 mpg. The new diesel engine will also be available on the GMC Sierra, but GM hasn’t released figures specific to that truck yet. You’ll need to pony up $3,890 to option the diesel engine onto the LT or RST trims, or $2,495 if you’re looking at an LTZ or High Country. Chevy says that this engine officially completes the powertrain lineup for the new Silverado, so all your options are now laid out on the table. Choose wisely.

One advantage of diesel that is overlooked.  Many contractors, farmers, loggers, etc. use heavy equipment, all which run on diesel.  They usually have a fuel truck on the work site to supply diesel to this equipment.  More than once, I've seen a contractor fuel his vehicle by taking diesel fuel from the fuel truck.  Big advantage in having a truck run on the same fuel as heavy equipment.

And it's totally illegal because they don't pay taxes on that fuel.

Depends on where the fuel comes from. If the fuel truck bought it at a filling station then the tax was paid. Now if it's home heating fuel oil then yes no tax and illegal.

True but I'd be surprised if equipment owners were putting that expensive stuff in their off road vehicles.  Unless the cheaper stuff wasn't available for some reason.

Not so much home heating fuel, more of a chance of a non-highway use tank providing fuel for construction equipment.  Here is Illinois' take on it:  https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=2ahUKEwi9qMXZ1NDjAhVHQ80KHd4SB1wQFjAAegQIAxAC&url=http%3A%2F%2Fwww.revenue.state.il.us%2Fpublications%2FPIOs%2FPIO-71.pdf&usg=AOvVaw1KY71dvvN9Xq6AuFZf5sHd

Great effort by GM but I have to ask whether this is what GM truck buyers were  really wanting.
Will it be a novelty buy that remains less than 10% of GM's 1500 truck sales or will it encourage some
to switch away from gasoline  engines, will Colorado buyers step up to a more efficient larger  truck?

Lots of questions.

Good point jpd80 sir. Diesel engine take rate for LD full size pickup trucks is still pretty low. I think F-150 Power Stroke is only 5% of total F-150 sales for example.

Now with electrification of cars and light trucks in full swing, you have to wonder if GM's excellent new diesel engine is too late to make a signficant number of LD full size truck buyers switch to diesel power.

IMO, diesel is a lost cause for anything lower than Class 2b trucks in the U.S. market.

The other thing that concerns me is that GM was almost obsessed with knocking off the competition
with superior fuel economy that it cost them a bunch in towing - 9,300 lbs in the GM 3.0 Duramax 
as opposed to 11,400 lbs in F150 Powestroke and 12,560 lbs Ram Ecodiesel The difference GM truck
buyers will find is a distinct lack of payload but I'll let other discuss the ramifications of the package...

I think people really mis-understand the fundamental difference between mid-size and full-size truck buyers. Not everyone has the room to park a FS truck, driving in an urban area is more difficult, or the capability is just not needed. I don't see people jumping from a Canyon/Colorado/Ranger to a full-size just because of mpg.

Recently Colorado numbers have dropped significantly, last months sales were about 8,500 - a 40% drop compared to last year.

Agreed, but they were on quite a tear March-Sept 2018. Sure would be good to see Ranger get up to these numbers.

If anything the rise in Ranger sales has seen a direct pull down of Colorado sales......
and I hate those averaged numbers in that table...

Colorado Sales  '19 ('18)
April.....11,655 (12,345)
May..... 11,060 (13,908)
June... ..8,549 (14,763)

Canyon Sales  '19 ('18)
April.....2,240 (2,960)
May..... 4,412 (3,603)
June....3,964  (3,072) 

Ranger Sales '19 ('18)
April.....5,748  (0000)
May..... 7,748  (0000)
June... .7,384  (0000)

It comes from a wholesaler and its dyed red.

Can a diesel hybrid be a thing?

That would potentially get ridiculously good MPG no?

It's certainly possible probowler sir. As you mentioned, diesel hybrid configuration has the potential to get very high MPG.

Mahindra proposed a diesel hybrid LD pickup truck about 10 years ago. It never materialized. https://www.autoblog.com/2008/02/11/mahindra-appalachian-diesel-pickup-arrives-in-us-next-year-dies/

It looks the big players in the LD full size pickup segment are focusing on gasoline electric hybrid systems and full BEV. Maybe if the new diesel LD pickups sell a lot better, one or more of those automakers will announce a diesel hybrid option. Remains to be seen.

It can be, but the on/off cycle keeps a diesel from achieving its highest efficiency. A small diesel parallel where electric is used as a supplement or a small diesel series where the engine charges the pack would be the only real applications.

The issue is with stop start emissions but for something like an extended range EV with a tiny two cylinder diesel driving a gen set at constant rpm, I think it could work

where CAFE fails is in addressing city mileage targets and all the fuel wasted by vehicles sitting in traffic every morning and afternoon.

hybrids basically level out city and highway mileage test numbers which really doesn’t help people who do lots of flat highway miles where regen braking does not come into play. A diesel like the new Duramax is going to really shine in lightly loaded Silverados or even those that tow 5,000 to 7,000 lbs

wonder if GM is planning any new full size SUVs with 3.0 diesel. Could be a great export potential
