The 300MPG car, too efficient for the US

Talk about crazy. This car gets 300 miles per gallon, yet it doesn't meet US "emissions standards". FFS, how much emissions are going to come from a car so incredibly efficient?

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. more
