The X-prize foundation plans to announced their newest competition next year a 100MPG car that will be production ready. Sounds like a greate idea but the fact is many cars already get close to 100mpg. In reality if the car manufacturers and oil companys wanted to build on it would allready be here. Henry Ford's model-t got 21mpg a hundred years ago on dirt roads. The average milage today is 25mpg. Weight is probably one of the biggest reasons for low mileage the American vehicles have been growing bigger since the oil embargo of the 70's. Aerodymamics todays vechicles are like blocks on wheels. Speed is another factor with the oil embargo highway speeds were reduced to 55mph and huge fuel savings now we all do 75mph. The Aptera Typ-1, a vehicle that can get 300 miles per gallon, will be available in early 2008 for less than $30,000 in both an electric plugin, and gas electric plugin hybrid version, the company announced Monday. In my opinion the oil companies want us to believe that they are out to provide us with high milage vechicles when in fact this won't happen until the oil and energy companies have a monopoly on alternitive energy.
