4. Project Background What is Baja SAE?
Baja SAE is a design and engineering competition as much as it is a racing series
RIT Baja competes all across North America against 100+ other teams
RIT Baja designs and builds a custom off-road vehicle from the ground up

5. Project Background
Vehicles must be able to handle all variety of rough terrain while excelling on challenging courses.
Vehicle success centers around efficiency, acceleration, and maneuverability, and driver skill.

6. Problem Statement
The RIT Baja Team has expressed an interest in improving drivetrain efficiency and dynamic control. The drivetrain has not had a significant format change since the 90’s, using a single speed reduction box coupled with a CVT. While this has been and continues to be an effective means of transmitting power to the wheels, and is the preferred solution amongst the top performing teams, the team would like to explore other options; specifically a gas-electric design. The team would like to receive a working bench top prototype of the drive system for the purpose of testing the gas electric system to compare it to the existing system.

8. Possible Advantages of Electric Drivetrain
Increased efficiency
Improved acceleration
Independent engine and wheel speed
Excess power storage
Regenerative braking
Active torque biasing
