Cruze Diesel is rated at 52 mpg highway in stick version, 37 mpg combined

2nd generation Cruze is louder on the inside. It's lighter and handles better, a consequence of the weight loss is less sound insulation.

Why is there such a large gap between city and highway ratings, or rather, why is the city FE so low? Obviously the Mk IV is a different car, but our highway is 48-52, and city is 42-45.

From 52 to 30, is what, a 40% loss?

I think I can answer from experience with the 1 Gen Cruze TD, and former 2012 Jetta TDI..

Its all emissions control. If the VW's were not cheating, I would bet they would see similar numbers. The compliant emissions demands higher EGTs to work, so in idle and city driving you burn fuel just to keep temperatures up, while on highway just the normal power level is sufficient to maintain temperatures.

I've seen higher highway MPG than the Jetta, pretty consistently, but lower city, and a slightly lower overall MPG as a result, now if the VW was made to comply, it would be interesting to see what those numbers would look like.

Some who have deleted have seen a 4-5 MPG gain on the Cruze TD, but it also makes the car run really cold, as the loss of EGR cooler flow, which helps warm up the engine, that could be a big issue in the colder parts of the country.

May be too optimistic, but I think VW would offer Diesels again in US. After all they're known for their TDI's cars and have been heavily invested in this technology. Plus they still sell TDI cars all over the world with great success,and will keep continue to develop/refine EA288 engine. Societies in general have short memory, and if VW could offer TDI's within next couple of years with the FE level that is similar to Cruze, I believe they would be able generate solid sales demands for their cars in USA

If, and only IF Trump guts the EPA, over the objections of his Al Gore loving daughter. The VW decision to stop all TDI's in North America after the cheat was to appease the Environmental activists/EPA and to minimize the massive fines that could have been imposed (they promised to put R&D $$$ in electric cars and hybrids).. I would like to see a competitive market where VW came back in, because competition makes all the options better!

Yes to competition diesel and electric. No to less EPA. Antarctica melting and sea rising much faster than predicted. I think that VW pulled out because they fell behind technologically since rather than doing research they were cheating. But yes I hope they catch up with clean diesel technolgy such as GM is leading now.

To me a Volkswagen w/o diesel is like peanut butter w no jelly!

I do like the Cruze, made close to me in nearby Lordstown, Ohio! I'll have to wait for a 10 year old one, haha!

If we found that temperatures were going down, would they want us to emit more CO2 to counter it? Global cooling would be more devastating than warming.. but that aside.. the emissions limits by the EPA are not CO2, per se (closest to that would be CAFE and MPG targets). The NOx emissions that VW cheated are not a factor in "man-made" global warming, they contribute to ground level smog, mostly in LA.. The DPF deals with particulate mass (PM), another non factor for "man-made" global warming, actually increased PM, while not good for breathing, would have a cooling effect, like when Mt. St. Helen's spewed ash in to the upper atmosphere and affected global climate, lower temperatures.. So in this case the requirements on diesel engines do NOTHING to help with the problem you believe exists, in fact they could make it worse, because that PM that normally would fall to the ground with rain, it is now burned in the DPF using ADDITIONAL fuel and making more CO2 and lowering MPG. It is important to understand the technology here, and what it does. Some who have deleted DPFs report minimal visible smoke without it, and MPG gains of 4-6, which means they are contributing LESS CO2, so if you believe that is causing man-made GW, then the EPA is not doing you any favors here on diesel emissions (I don't believe man's contribution is significant, because there is no verifiable proof, and all models that predicted temperature rise with CO2 have been proved incorrect).

Diesels emit 30% less CO2 than gassers. Therefore clean diesel (of NOX) is key to both climate change and smog since clean means driveable safely with the CO2 reduction. That is the most important climate related aspect of diesels, they are high mpg and low CO2 (and great cars). Anyway man-made CO2 is the major driver of climate change today, not PM or soot.

 

[turbobrick240]

Well, we have the head of the EPA denying CO2 plays a role in climate change. Science is for chumps! Pretty soon we'll be watering our crops with gatorade.

 

[rotarykid]

there is also a push to end all national tax based electric car subsidies which would in short order end the electric car offerings in our fleet outside of CARB areas like kalifornia.....

The politicians and the petro companies don't want us to get away from dino fuel!
