General Motors will reportedly delay the introduction of its new six-cylinder diesel engines for the new generation Silverado and Sierra. Anyone following the diesel vehicle trends in America should not be surprised. Volkswagen's cheating scandal changes things for automakers who want to use diesel engines globally, and in the U.S. in particular. Ram's diesel fiasco didn't make things any easier for automakers who want to use diesel engines in trucks. The upshot of the cheating and other "misunderstandings" is that diesel vehicles draw close scrutiny now. With billions in fines now paid and even some employees in prison, nobody at GM wants to launch a diesel vehicle without giving the EPA the opportunity to do any testing it wishes to do prior to launch. Most vehicles are self-certified by automakers, or are tested by third-parties. We suspect that zero diesel vehicles will be in the future. The EPA is all over these known polluters to ensure compliance.

 

Other manufacturers, notably Mazda and Hyundai had previously announced plans to introduce new diesel engines in America and then opted not to. We do not think GM will back out. GM has already staffed and prepped the Flint Engine Plant to build the new diesel engines. 

 

Motor1 reports GM spokesperson Monte Duran as saying, "Yes, we are shifting the 3.0L Diesel from a late 2019MY to a 2020MY as emissions testing is taking longer than expected. However, we did not attribute to a single entity, as the truth is this is a collaborative effort between GM and several government entities. We will make the 2020MY Duramax available for dealers orders soon, and expect to deliver the first trucks to customers soon after emissions testing is complete."

Wow! Delayed a whole Year?

I guess better late than wrong.

Maybe they are trying to figure out how to achieve running on pure Urea/DEF/Govt. Juice?

It's not delayed a whole year.  It's my understanding it was supposed to be available for the tail end of the 2019 model year (so you could get a 2019 built about now or soon with it.  Instead, GM is delaying it a couple of months, which means it will only be available in 2020 model year trucks.

This.

By September-October you will see them on the road. There is no reason to put the 3.0 in a 2019 since 2020 are gonna start getting built in probably less then 90days. The delay sucks but laws are strict. I had some stuff planned that I wanted the truck for this summer but getting it around my birthday is alright I guess haha

LOL....  I took MY as May and not "Model Year"

Last sentence in the first paragraph, we suspect zero new diesels in the future. Wow. 

[Stex]

From what I have read, the new diesels, with the complex emissions controls and additives, are problematic.  Especially in cold climes.  I was considering this one, but will be slow to go for it till proven. I have done way to much consumer field testing for GM.

 

Also the 6.2 is some what proven. DFM still not proven.

As someone who owns multiple DEF diesels, you couldn't pay me to take one if there was a gas option. 

[SierraHD17]

Yup....  useless where it's cold unless deleted. And if it's going to cost like 5K plus to delete like the L5P it's not worth it.  There is literally zero advantage to buying one.  They should have released a baby Duramax back in the GMT800 trucks... would have sold like mad.

It's saying that zero diesels will be self-certified or tested by third parties in the future.

No...will be Zero diesel vehicles for GM’s future after the Bosch CP4 fuel pump  Federal Class Actions...aint compatible with US Diesel.

 

Brings me back to the mid 90’s in Europe and all of the GM 6.2L diesels were dropping DEAD and needed cold water poured over the injection pump to start back up...European diesel was toooo dry for GM Diesels

 

I drove the first 6.5L turbo diesel to hit Europe on the Autobahn and blew every single gasket on that motor cruising at 110-120ish for a couple hours...she ate that dry Europe diesel up.

I had a neighbor who had a 2014 Grand Cherokee Ecodiesel.  Ordered it months in advance, delivery was delayed due to reprogramming transmission and non-stop issues once he owned it.  Several times he limped that bad boy right into the dealership on his way home from work.  He ended up lemon law-ing it back to the dealership. 

 

I try to avoid first year redesigns (own a 2014 so that personal rule didn't work well) but I would be very hesitant to own a MAJOR resign like this at least for the first 1-2 years until all the real word feedback helps iron out the kinks.

 

Imagine the premium you're going to pay for this too.  Probably $3.5k-$4k more?
