99 Teams Attended

Suspension & Chassis Team• All new suspension geometry & components• New optimized chassis tailored to the suspension points

Drive-train Team• New dual reduction gearbox with Forward-Neutral-Reverse & inboard brakes• Custom CVT system-Senior Design Project• New drive shafts

Composites Team• Continued development of composite manufacturing techniques• Front & rear upper suspension links• Steering post holder• Front lower suspension arms

Flotation & Propulsion• Flotation for the 2009-10 vehicle• New adjustable fender

Data Acquisition System• Stand alone data acquisition unit• Strain gauges, accelerometers, temperature sensors, etc.

Dry weight < 375 lbs◦ 15% reduction from 2009◦ Smaller and more robust chassis◦ Improve FEA to optimize components

Acceleration Time < 4.8 seconds◦ Reduce vehicle weight & reduce rotational mass◦ New gearbox: improve efficiency◦ New CVT: improve efficiency and greater shift range

Develop Data Acquisition System◦ Record “road load” data◦ Benchmark vehicle design and compare simulations◦ Use data to create accurate simulations in the future
