Inefficient fuel usage is unavoidable for many vehicles; especially vehicles that operate in frequent stop and go situations. With increasing fuel prices, there is a glaring need for a more efficient solution. The solution investigated by Team 4 was a series hydraulic hybrid system. One of the major benefits of a hydraulic hybrid over other hybrid types includes less energy conversions in the drive train. Some of the benefits of a hybrid compared to a normal gas-driven vehicle include regenerative braking, optimized operating speed of the gas engine, and the ability to completely shut the gas engine off when power is not required.
