Don't forget that this diesel in not from the USA it is made and designed in Italy.

My father had a 1986 ford Escort diesel that got  50 mpg rock solid.  once up to speed would cruze all day. It did not have a lot of power, as turbos were only on large over the road trucks then. 

When you consider there are gasoline cars that can get close to this MPG,  the difference in price buys a lot of fuel. 

I am surprised we are not seeing more MPG, especially when you consider the technology explosion in engine managment that has ocurred.

Thanks Iron, I nver knew that !!

Anyway, my main point was that I have personal exoerience between hybrid and diesel performance, which still makes the increased tax worthwhile.

To Charles point about Eupoean diesel engines, they certainly have taken a big jump in both performance and MPG in the last 5 years. My wife previously had a older technology Citroen diesel C4 and that gave no better performance than her current hybrid.

Good points, gbergman. In this case, the technology in Europe and the U.S. will be nearly identical, since this is a European-designed engine.

I agree for the most part with bob from maine.  Other threads blame GM etc for bad engines.   But the main reasons for the dislike of diesel are soot and smell.  Personally the Manufacturer that did the most to put a bad rap on diesel is Mercedes.  Their older cars with the soot pouring out at every acceleration were horrendous! The entire rear of the Mercedes would be black from soot.  They smelled horrible to even be around, etc.  For some reason there were quite a few on the road.  Poor man's Mercedes?  Now we have the Dodge Ram trucks that people are hopping up that pour the soot out.  I have not been in the emissions business in several years but I understand that at least here in California there are steps to regulate the amount of soot.  Finally!  IMO American manufactures should not be allowed to sell their version of diesel engine, I understand in Europe the technology is much better.

Be careful when comparing European MPG to US MPG.  In the UK, a gallon in 4.55 liters, but in the US a gallon is 3.8 liters.  That makes european MPG seem about 20% higher.

Misunderstanding of UK tax and mpg

Seeing the comments below, I just wanted to point out that the UK also taxes diesel more than regular, but the mpg more than makes up for it.

I drive a Peugeot turbo-disel and get 59mpg, whereas my wife has a Toyota Auris hybrid and only gets 42mpg. I also get much better highway performance due to the significantly higher torque, so my one surprise is that the GM US mpg is so low.

@Marvin McConoughey :

Yes, GM did have a lot of expertise with diesel engines:
  • Detroit Diesel made engines for use in GMC truck and busses, and for sale to other truck manufacturers. 
  • Electromotive Division made its own engines for its locomotives.
  • GMC Truck & Coach made its own engines for trucks, as well as for driving irrigation pumps. (I don't remember exactly when they stopped, but they built the GMC motor homes in the same building--Building 29--that they used to build engines in, and that started in 1973.)

Sometimes different GM divisions worked very well together. But I think that was more the exception than the rule. There were not well-established communication paths between the divisions, and sometimes there was a bit of not-invented-here syndrome, so it would not surprise me if the problem were that the people designing the Chevy diesel engine did not have access to all the design wisdom that existed in the other divisions.

I don't know any of the specifics of that particular engine, but this would make sense based on my experience working at GM for several years. (BTW, the problem isn't just GM. My experience is that in huge corporations, sharing of information is awful, because people don't know who has the information and how to get access to it.)

Ratsky, the point we were trying to make is that diesel fuel in Europe is taxed differently than gasoline in Europe. A representative from GM and another from the Center for Automotive Research used the term "diesel subsidy" -- meaning that diesel fuel isn't taxed quite as heavily over there as gasoline is. If there's information to refute that, I'm certainly open to hearing it.

I retired my '84 300D after 375K miles when the lift went through the rocker panels. Maine winters and road salt ate my car! The American market has not been receptive to diesel engines. The stigma of driving a smelly, sooty, slow accelerating, noisy vehicle which made your hands and clothes smell when you filled the tank was too much to overcome. Add to this the premium cost of initial purchase and inability to get anyone other than the dealer to service the engine and it becomes difficult to convince buyers. Volvo and Peugot in the 70's and 80's had a low compression (18:1) diesel which smelled terrible, accelerated poorly, and due to lack of sympathetic service mechanics usually were fairly unrelible. VW and Mercedes never gave-up but their sales were quite slow and diesels owners became almost a cult. Because of the legislation to limit soot, both companies had to come up with particulate filters which needed frequent changing, plus as the compression ratio was upped to increase fuel efficiency, temperature and thus NOx emissions went through the roof which required heroic efforts to meet emission laws. Today's best diesel engines meet (for now at least) the soot and NOx limits set by CA, but there is every indication that new laws will be enacted to further limit soot, odor and efficiency.
