The Electrical Vehicle Team Needs an
Electric Powertrain for a vehicle
registered as a motorcycle to operate
at highway speeds and a long enough
range to compete in the Green Grand
Prix

Constraints:
Assume Rolling Chassis Ready by MSD I in FALL
includes: frame, wheels, steering,
seating, brakes, suspension.
Able to register as a motorcycle
Operates at highway speeds
Range Appropriate for GGP
Next Steps/Concerns
 Rolling
Chassis ready for powertrain
required by Start of Winter qtr. at latest,
(preferred by Fall qtr.)
 Funding for Vehicle, Budget Required
 Can’t achieve range w/ lead acid
batteries
 Approach Tesla for crash test car batteries
