I read an amazing article in The Atlantic Magazine yesterday. Auto engineers have made quantum improvements in engines, transmission, electronics, etc. Gas mileage should easily be 60 mpg+. However engineers have not been able to make cars lighter and this has inhibited improvements in gas mileage. A group of engineers just built a car with a body made of carbon fiber. (This is the material used on the Boeing 787 Dreamliner body.They made the car 's frame out of chromaloy steel. This vehicle got an amazing 52 miles per gallon gas mileage, The engineers claim that the car is safe in a crash.
