It looks like the next big leap (maybe the last?) in internal combustion engines will be Homogeneous Charge Compression Ignition.. gasoline engine deliberately creating and using knock or pre-ignition to ignite a part of the fuel air charge in multi part injection process to better control and slow the main charge ingition, whether or not that is done by regular spark plug, which depends on rev range, driving conditions etc.. Formula one engines are just starting to use it the past two years.. fascinating stuff.

Utah has done this for years, emissions limits are much higher outside of the Wasatch front and Logan. The bigger impediment (and maybe this is what you meant) is that no manufacturers will bother making vehicles specifically for those smaller markets since it's not profitable.

This is who the EPA should be going after:

"It's not clear how many trucks are involved. One truck manufacturer called the group "a niche inside a niche." "
I think expecting the EPA to hand out tickets in yer home town is a stretchLee Lau - xxx-er is the laziest Asian canuck I know

On vehicles? That's the first I'd heard of such a thing. I suppose you could do it based on registration location, but it seems like a PITA to implement. In CA it wouldn't make a whole lot of sense because relatively few people live outside the LA-OC-SD area (where smog is bad), Inland Empire (likewise), Central Valley (even worse in many places), and Bay Area (mostly less bad than the others but still bad, and densely populated). Then, of course, we have prevailing winds off the ocean that concentrate particulates to the east of where they're actually emitted.
Fixed point sources of emissions are different and easier to deal with (e.g. local air quality management districts).
Your second point too though.

Colorado only requires vehicle emissions testing for the urban part of the state. Essentially Denver, Boulder, Fort Collins, Castle Rock. The rest of the state has no emissions requirements. It is based off the address where the vehicle is registered.

In England right now driving a fun, fuel efficient Seat Leon FR- just got back from italy where I was driving a comfortable, spacious efficient diesel Nissan Qashqai.
I used to wonder the same about euro vs us cars, looking at the same car, same drivetrain, and much better mileage on the UK version.
We can achieve the same MPG if we follow their lead:
1-Pollute more. plain and simple, our emissions regs are more stringent.
2-Use bigger gallons. A car that gets 40 mpg on a US gallone will get 48 mpg on a UK gallon. This is an environmentally friendly way to raise mpg.
There are car models here in the UK simply not available in the US, but a lot of that has more to do with our free market economy. americans don't like downshifting, and are not willing to drive a Yaris with 68 BHP. I think my last motorcycle was just over 100 bhp.

VW Cheater Diesels
I believe this is all about exceedances with the national ambient air quality emission standards, whether air basins are in "attainment" with those standards, plans at the state level to have those basins come into attainment, and plans at the local level to meet the state implementation plans. Each state (and some tribes) can have autonomy to get into attainment. Complicating things, Cali has its own standards that are generally more strict than the EPA. I am guessing that several other states do, too.
Why is nobody discussing biodiesel (b20) hybrid vehicles?

The trouble with bio, it clogs up the engines and you have higher Maintance cost.
We have a fleet and our own tanks. We buy the lowest (2%) allowed.

Biodiesel made from soybeans leads to even more soil erosion and fresh water use than corn ethanol. Gels in the winter.

You can run almost anything in an old tech engine like a 7.3 ford but bio or wvo don't work flawlessly in a modern TDi engine

Interesting. I believe San Francisco is bringing in a diesel hybrid bud fleet that will run b20, granted SF has a pretty good climate for it. I'm not sure about the source for the b20. Isn't mammoth using bio for their genies? I'm not sure about their source, either.

There is a statistic floating around at the moment
which really makes the point: if the levels of efficiency in F1 engines were applied to road cars across the board, the average fuel consumption on a road car would be 165 mpg.

For VW TDI owners, onslaught of letters from lawyers deepens the sense of betrayal

I guess I have owned 4 VW's being a westy, a karmann ghia & 2 TDi's
I don't really care about the betrayal, I would look at how this affects resale and the need to pass any emission testing in your jurisdiction, if you are going to drive this thing forever resale may not matter but if you can't license the car that is a huge probelmLee Lau - xxx-er is the laziest Asian canuck I know

Sure some.. Maybe not a large part though.
The current engine formula with limited total fuel, fuel flow rate, turbo, MGU-K, MGU-H and energy store is leading to huge improvements in efficiency... extracting every last joule of energy from each liter of gasoline is fundamentally beneficial for future series production cars...
On the newer diesel trucks, removal of all emissions equipment
It would be interesting to know what the Audi and Peugeot diesel endurance racers spat out in terms of emissions?

Ah, this is like Lance Armstrong scenario for cars. People are going to persecute solely VW but I'm sure everyone is doing the same darn thing...http://www.bloomberg.com/news/articl...-of-automakers
Also, if anyone thinks selling their VW TDI right now solely because their car is not as clean as they once thought/their individual impact on the environment. Don't worry, the other 20k diesel owners in Iowa blowing lines of black soot out of their straight piped 3/4ton trucks will make up for it.

Ford's New "Game Changing" EcoBlue 2.0 Diesel. I wonder if this will make it to this side of the pond?
