You will NOT see the Xl1 in America
Volkswagen?s New 300 MPG Car Not Allowed In America Because It Is Too Efficient | Spirit Science
The XL1 will not meet American emission standards NOT because it is not clean enough, it will not meet them simply because inefficient parts that are mandated by the EPA are not part of the XL1?s power train. We will never see truly clean running and efficient cars in America, because the FED has mandated that American cars be intentionally stifled by horribly fuel wasting parts that add to the cost of the vehicle and do absolutely NO GOOD, how much more efficient and clean can you get than 300 mpg? The exhaust from the Xl1 has to, by simple math and the laws of physics, run at the theoretical threshold of emissions perfection.
...
What does that kind of fuel economy really mean?
If the XL1 was equipped with an 18 gallon fuel tank, and you did all highwaydriving, you could fill it up with an oil change and when the next change was due you could change the oil and keep driving without filling up for and additional 2,400 miles. But it comes with a much smaller fuel tank, because if it could go that long on a single tank chances are the fuel would foul before it got used. The tank is only 2.6 gallons to prevent fuel age related problems from happening. So fill ups are cheap.

I had suspected that Suspect posted this nonsense.

Years ago I had calculated that it should be possible to get a small car to exceed 100 mpg by putting parallel direct to cylinder water injectors side by side with the fuel injectors, and using the exhaust manifold to preheat the water so it would enter the cylinders as dry steam, thus providing added expansion (which drives the engine) while allowing the combustion process to proceed without reducing it’s efficiency. But I was obviously wrong with my calculations, because they were in fact over 2x conservative.

It injects dry steam into the combustion chamber? I didn't know steam could be dry. Also, I didn't know it was efficient to create the steam first, and then force it into the combustion chamber.

Yea, that article is a load of BS.
What are these ineffective parts mandated by the EPA that the XL1 does use?

A few things:
1) The XL1 doesn't get 300mpg, and VW has never claimed this. The official rating is an American-equivalent 261mpg, and the number is only that high because it counts the use of electricity from the grid.
2) Fuel tank size: the Volt has a large tank, yet the cars are intended to run on grid electricity most of the time. The car simply runs the engine at a specified mileage interval from its last use. The Plug-in Prius does the same. It would have been quite easy for VW to do this with the XL1. It doesn't have a larger tank because of packaging and weight reasons.
3) This article has been linked here many times before. Many times before. It is still just as stupid and uninformed.
