Continuous Speed on Level Hard Surface Design Criteria: 20MPH Design Criteria: 20MPH Critical Critical Function of horsepower and rolling resistance; (increased off-road traction will increase rolling resistance) Function of horsepower and rolling resistance; (increased off-road traction will increase rolling resistance)

Grade/Slope Climbing Design Criteria: 60% Design Criteria: 60% Very important Very important This may compromise payload capacity and ground clearance This may compromise payload capacity and ground clearance

Payload Fraction (%GVW) Design Criteria: 40% = 2000lbs. Design Criteria: 40% = 2000lbs. Critical Critical Will compromise speed, handling, acceleration, fuel capacity and range Will compromise speed, handling, acceleration, fuel capacity and range

Range on Cross Country 7.5MPH) Design criteria: 75miles Design criteria: 75miles Critical Critical Will depend on specific cross country terrain encountered Will depend on specific cross country terrain encountered Fuel used to meet this requirement will subtract from payload size and weight Fuel used to meet this requirement will subtract from payload size and weight

Side Step Clearance Height Design criteria: 24 inches Design criteria: 24 inches Somewhat important Somewhat important This implies substantial suspension travel/ground clearance/large tires or a combination thereof This implies substantial suspension travel/ground clearance/large tires or a combination thereof Increased side step clearance height will compromise grade/slope climbing and fuel consumption Increased side step clearance height will compromise grade/slope climbing and fuel consumption

Tractive Effort/GVW Design Criteria: 1.0 Design Criteria: 1.0 Desireable, though not very realistic. Desireable, though not very realistic. Only 0.5 required to meet 60% slope requirement Only 0.5 required to meet 60% slope requirement Very difficult to attain on dirt Very difficult to attain on dirt

Wearout Important Important Vehicle expected to operate in areas where maintenance would be difficult. Vehicle expected to operate in areas where maintenance would be difficult. Longer interval between service requires higher precision parts, costing more. It may be more cost effective to service the vehicle more often than to create an ultra low maintenance vehicle Longer interval between service requires higher precision parts, costing more.
