We ran an article on this last year. It shows how far you can push the envelope of MPG with great engineering and aerodynamics. The VW Though the XL1 can hit 300 mpg under ideal driving conditions, typically a little over 200 mpg.
Sadly, Volkswagen is only making 250 of these tiny diesel hybrid two-seaters, and they’re only going to sell them in Europe where they retail for about $150,000 in our currency. They will not be available in the USA . The XL1 is a mid-engine, two-seat, rear-wheel drive car with a an 800cc turbodiesel engine coupled to an electric motor that gets power from a 5-kWh lithium-ion battery pack. It only has 74 combined horsepower and weighs 1,700 pounds thanks to its plethora of carbon fiber, magnesium wheels and other measures. It also trades side mirrors for video cameras mounted in the doors.
The following is from an article published by tehe the The Mind Unleashed :http://themindunleashed.org/2014/04/volkswagens-new-300-mpg-car-allowed-america-efficient.html
(Editors note MD) I actually do not agree with all what is said, however one of our readers asked if I could cover this and it is raises some issues worth discussing. The information about production numbers and costs is also different from my other sources.
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 leisurly 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.
YOU WILL NOT SEE THE XL1 IN AMERICA
Even it’s far less efficient 85 mpg non hyrid full size station wagon counterpart – the Jetta TDI blue motion wagon (Pictured right, credit Carscoops.com), which is made in America is banned from American roads. And I would like to ask why? What excuse is there for banning highly efficient cars from American roads?
One excuse is that “they don’t meet American crash test standards”, but the real truth is that the Fed simply refused to ever crash test them because of what they are, in Europe even the XL1 is considered to be a very safe car in crashes, and the Jetta station wagon is obviously even safer and you CAN buy the non TDI versions of the exact same car in America. The only thing different is the engine, WHAT GIVES?
The answer is obvious. Simply for the sake of raking in huge profits from $4 a gallon gas, getting guzzled at 10X the rate it should be, the corporations have via campaign contributions and other types of pay outs succeeded in getting the FED to legislate the best cars off the road for irrelevant trumped up reasons. 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.
ALL IS NOT ROSY FOR EUROPE HOWEVER
The Xl1 is SO MUCH the car that the oil companies do not want that there will only be 2,000 made. And no production line was set up for them, they are all hand made. And irrelevant “lightweight” parts are added to the frame, consisting of carbon fiber and other exotic materials to add to the mystique.
But the materials and production limits are a load of BUNK, the car STILL weighs over 1,700 pounds, if it weighed just 100 pounds more everything exotic could be removed, because “exotic materials” are not doing much anyway, they are just marketing.
Cost is not the issue either Even after being hand made with “exotic” materials in an intentionally limited edition, the Xl1 still only costs $60,000. There is a lot more of a market for this car than 2,000 units at that price, have no doubt, this car is being held back on purpose.
If it can be hand made for that little, automated assembly lines could do it for half. And if a 1,700 plus pound Xl1 can get 300 mpg, a 3,400 pound Chevy Truck should be able to deliver at least 150 MPG, the Xl1 lays the mileage scam bare, with every hybrid that gets 40 mpg and every truck off the line that gets 20, Americans are getting the shaft and they do not even realize it.
I was first infatuated and impressed with the 85mpg Vokswagen TDI Blue Motion wagon and wished I could get one in America (when I was still there), and then the 300 mpg Xl1 came along, what a rude awakening and slap in the face for the American car buyer.
