You won’t find the 300 MPG Volkswagen XL1 in an American showroom, in fact it has even been denied a tour of America because it is too efficient for the American public to be made widely aware of, and oil profits are too high in America with the status quo in place. No tour has been allowed for this car because the myth that 50 mpg is virtually impossible to obtain from even a stripped down econobox is too profitable to let go of, and when it comes to corporate oil profits, ignorance is bliss.
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.
The 100 mpg carburetor was indeed a reality, and the Volkswagen XL1 proves it with only straightforward nothing special technology we have had since the 1970?s.Though the XL1 can be plugged in to deliver a 40 mile all electric drive, it does not need to be plugged in EVER to achieve 300 mpg. And it does not cheat in any way to achieve the rating, it weighs over 1,700 pounds, has normal tires, and delivers a very good driving experience with a governed top speed of 99 mph. The XL1 could reach a top speed in excess of 110 mph absent governor and turns in a 0-60 time of 11.5 seconds which is by no means leisurely for a car designed for efficiency. The XL1 in no way cheats on performance to hit it’s rating. It is simply the car we should have always had, and have had taken from us in the name of oil profits.
