Students from Brigham Young University created a carbon fiber vehicle for the Shell Eco-marathon that achieves 2,145 miles per gallon. The lightweight three-wheeler uses a tiny 30-milliliter ethanol tank to maximize efficiency through extreme weight reduction and aerodynamics. While the vehicle is limited to a 23 mph top speed and requires a driver under 120 pounds, it demonstrates the potential for extreme efficiency in internal combustion design. This project highlights how aerodynamics and material science can drastically reduce fuel consumption.
