Results

Base Case CartHydraulic Hybrid CartStop and Go Fuel Economy13.9 mpg21.1 mpg

52.4%

increase in average stop and go fuel economy

Improvements

Different pump or hydraulic motor

Variable displacement motor

Check valves with lower cracking pressure

Design to eliminate minor losses

Business Plan

Target MarketPackage delivery, garbage trucks, city busesIntroduction to the marketO.E.M.Retrofit is to expensivePotential SavingsHigher gas mileage, lower maintenance costs

Business Plan

FeasibilityHigh cost on prototypePay back period is 19 years at current gas prices ($4.20)Longer than the life of the vehicle

Component Failure

Conclusions

Met our goal!

Met efficiency expectations

Proved our system works

Very expensive system

Learned a lot

Had fun!
