They could have saved us all some grief if they would have taken advantage of modern technology to control emissions. A Dutch firm called Amminex developed a cartridge based SCR system several years ago that is so effective it eliminates the user having to add DEF and it eliminates the need for cooled EGR setups on diesels. It never freezes up in cold weather like DEF can. And the cartridges are recyclable and can be sized to last for the OEM vehicle recommended oil change cycle. Pull one out, replace with a new cartridge, and go on your way. No mess. And by eliminating the need for EGR, the DPF regens are less frequent and the DPF systems last much longer with fewer issues. Unlike a normal DEF / SCR system that requires injector to dose DEF (33% urea and 66% water) into the catalyst, the Amminex system delivers 100% urea in a gaseous form to the SCR. No injector or DEF filter to go bad. No crystallization of DEF fluid that can choke DEF filters and injectors.

And this system has met EPA guidelines. The OEM's still have their head stuck where the sun doesn't shine. And they think they are high tech. Give me a break.

Yea this is exactly why we got one of these for my wife, she commutes 100 miles per day to and from a hospital that has a zero tolerance policy when it comes to calling out in foul weather. In the warmer months she averages 42ish, in the winter she averages 39 - 40 with the heavy AT's I put on, having such a highly efficient AWD vehicle has been very nice, she loves only having to fill up once a week. Also as far as fuel costs, regular around here last i looked is right around $2.99 a gallon, and diesel is about $3.19 so the extra cost of diesel is easily covered.

Sounds like you're a perfect fit for the AWD diesel.

Very odd pricing difference over time...when the price of regular was around $2.00 a few months back...diesel here was around $2.70 now that regular is near $3.00 the difference fluctuates between diesel and regular is 5c to 20c
and even reversed one week where diesel was cheaper by 5c...so the difference is not really due to taxes.


Sorry for diverting from the topic that chevy is killing AWD diesel, i find it weird as the 4WD or 2WD system has nothing to do with the engine ...they could have kept it for on order only. Its not like they are stopping 4WD transfer case production or some thing like that.


May be it is a sign they might drop this diesel engine totally in a year or two...remember that GM now buys this engine from opel who they sold to Peugeot...so no longer a GM operation.

I would agree with that statement as the take rate on the diesel isn't very strong, and I don't think GM ever met the sales goals they were seeking. Adding to this the Cruze is no longer in production, leaving just two vehicles in GM's lineup that make use of this engine.

I don't think it was GM not meeting their sales goals, rather it was 10 years late to the diesel party. Gas engines have really narrowed the gap in the fuel economy area to the point that it will take years and years to justify the difference in fuel price and cost of initial purchase. I will grant you that 40 plus mpg is fabulous and nothing to sniff at but unless the vehicle is leased and can be returned after 3 years the true cost of the diesel will be revealed after the warranty is over and the very high costs of even basic maintenance will blow the mpg out of the water. While service is gotten better its still a chore to find shops that will even work on them as Dodge, and Ford found out to their dismay as they had to send their customers to International dealerships and Dodge to Cummins Service Centers.

And it didn't help things when VW got into trouble with its diesel programming and got hit hard by the EPA.

GM had a major stake in VM (not VW) engines of Italy. They dumped their stake in VM when they had their financial woes and bail out stuff went down. VM makes some good diesel engines. I had one in my 2006 Jeep Liberty. GM did steal away the main engineer on the 2.8L VM diesel and rebranded the VM 2.8L as their Dmax that is now in the Colorado / Canyon pickups. That motor was developed when GM was still in VM, so they really didn't steal the design. Except for a couple of minor details, the engine is identical to the 2.8L VM diesel I had in my Jeep. At least they got that one right.

Folks in the U.S. are more comfortable with gasoline engines in their cars. Diesel has an uphill battle to gain market share in the U.S. Many folks just aren't perked up when the word diesel is mentioned. I only use diesel for my commercial stuff. If it was practical to walk away from diesel and never deal with it again, I wouldn't even let the screen door hit me on the way out. Retirement just can't get here quick enough!

Same here, but not quite so far of a commute. Plus we keep our cars until they die, so it will pay off in the long run. All three of our vehicles are diesel (Dodge Ram diesel and VW Passat TDI) so I only need to keep one fuel handy for emergencies.
